    [0001] The present invention relates to a dry or paste mortar composition for an interior coating or coating having ambient air purifying properties. BACKGROUND OF THE INVENTION Indoor air is a mixture of physical, chemical and / or biological pollutants that may have different origins. The building materials, finishes used and the furniture are in particular the origin of the emissions of volatile organic compounds (VOC) such as for example the optionally halogenated hydrocarbons, the alcohols, the organic acids, the esters or the aldehydes, as formaldehyde, acetaldehyde, hexanal ... VOCs have a sufficiently high vapor pressure at room temperature and so they can be almost completely in the vapor state in the ambient air. They can be emitted from these materials or products for longer or shorter periods, which range from several days to several years depending on the nature and type of material or product from which they come. Particleboard, agglomerated or plywood, textiles used for furniture or decoration, wall or synthetic floor or prefabricated flooring, varnishes, adhesives ... are known to emit formaldehyde. It is recommended, for example, to ventilate parts significantly during or after the use of these products. The regulation of the protection against undesirable emissions of products that may pose health risks is becoming stricter and requires the reduction of pollutant emissions as much as possible. For this purpose, it is sometimes possible to act at the source by avoiding their production. In some cases, this is not possible and it is then necessary to act after the formation of the pollutants, either by destructive techniques such as oxidation processes, irradiation or biological processes or by recuperative techniques such as adsorption, condensation, membrane processes or absorption. The building materials having air purifier functions used so far mainly use these two types of technologies: for example, photocatalytic oxidation with titanium oxide particles which can be incorporated into compositions. mortars, or the use of adsorbents or chemisorbents, capable of trapping VOCs and especially aldehydes. The disadvantage of the processes involving catalytic oxidation is primarily the need to have an adequate light source in the room for the process to be efficient. As regards the processes using adsorbents, it is in particular known to deposit on the support a composition which forms a film which contains an agent capable of reacting with formaldehyde and consequently of trapping it. Among these compounds capable of trapping aldehydes are active methylene compounds, tannins, amides, hydrazides. However, it is essential when these compounds are used on decorative coatings that they have no negative impact on the aesthetic appearance of the coating. The agent capable of trapping the aldehydes must not leave traces or cause discoloration of the surface on which it is placed. On the other hand, this agent must not emit foul odors or cause emissions that would be opposed to the desired effect. It must therefore remain stable under the conditions of use of the material in which it is incorporated or on which it is deposited.
    [0002] Commonly used formaldehyde scavengers belong to the family of acetoacetamides. When such compounds are introduced into cementitious matrices for finishing coatings, a strong ammonia odor due to the hydrolysis of the amide under alkaline conditions is detected after a few days in the room. This type of compounds can not therefore be used for the desired application. This odor disappears if the acetic acid-based scavenger is used under conditions of neutral pH, for example in a plaster-based coating. On the other hand, even under these conditions, after a few days, a yellow-brown discoloration is noted on the surface of the coating, which is not acceptable at the level of the aesthetic appearance. It is therefore necessary to use other types of agents capable of trapping aldehydes that do not have the aforementioned drawbacks for uses in alkaline and / or decorative mortars. This is the context of the present invention.
    [0003] The present invention relates to a composition of dry mortar or paste for coating or interior coating comprising at least one binder, at least aggregates, aggregates, sands and / or fillers and at least one additive, one of said additives being an agent in the form of a powder, capable of trapping aldehydes, and chosen from aminoalcohols. This additive is also called depolluting agent. It is directly incorporated in the mortar composition, without modifying the physical and mechanical properties such as the setting time or the mechanical strength of the mortar. The mortar composition according to the present invention can be in powder form and is then referred to as a dry composition. Ale can also be in the form of a dispersion and will then speak of a paste mortar composition. The depolluting agent is preferably a primary aminoalcohol of formula RIR21 = 3-C-NH2, in which R1, R2 and FF are alkyl groups comprising from 1 to 6 carbon atoms (C1-C6), hydrogen atoms or hydroxyl groups -OH, at least one of the groups R1, R2 or R3 comprising a hydroxyl group. In a preferred manner, the depolluting agent is chosen from 2-amino-2-methyl-1-propanol, 2-amino-2-methyl-1,3-propanediol and (hydroxymethyl) aminomethane. hane, 2-no. 2-ethyl-1,3-propanediol. The depolluting agent has an absorption capacity such that it absorbs the aldehydes present in a room and therefore purify the indoor air. The aldehydes that are absorbed by the depolluting agent are formaldehyde, acetaldehyde, propionaldehyde, cronotaldehyde, butyraldehyde, benzaldehyde, valeraldehyde or hexaldehyde. The mortar composition comprises at least one inorganic or organic binder, which may be a hydraulic binder, a source of calcium sulfate, a phosphomagnesium binder, lime and / or polymer dispersions or redispersible powders.
    [0004] The inorganic binder is selected from hydraulic binders, calcium sulphate sources, lime and / or phosphomagnesium binders. Among the hydraulic binders, mention may be made of Portland cements, aluminous cements, sulphoaluminous cements, belitic cements, blast furnace slags, pozzolanic mixture cements possibly including fly ash, silica fumes, limestone. , calcined shale and / or natural or calcinated pozzolans. It is possible to use in the mortar composition according to the present invention this type of binder, alone or in mixture. Sources of calcium sulphate include plaster or hemihydrate, gypsum and / or anhydrite. When the binder is organic, it is chosen from polymer dispersions or redispersible powders. There may be mentioned acrylic and / or vinyl polymers or co-polymers, styrene and butadiene copolymers, copolymers of styrene and acrylic acid, copolymers of vinyl acetate and ethylene, copolymers of vinyl acetate and vinyl versatate, and their derivatives. The amount of binder, mineral or organic, represents between 1 and 95% by weight of the total amount of the various constituents of the dry or paste mortar composition.
    [0005] The dry or paste mortar composition contains aggregates, aggregates, sands, and / or calcareous and / or siliceous fillers. These compounds play in particular on the rheology, the hardness or the final appearance of the product. Their content is generally between 1 and 95% by weight relative to the total weight of the composition.
    [0006] The dry or paste mortar composition according to the present invention advantageously comprises, in addition to the depolluting agent, additives which are rheological agents such as plasticizers or superplasticizers, water-retaining agents, thickeners, biocidal agents, dispersants, water-repellent agents, pigments, accelerators and / or retarders, and other agents for improving setting, hardening and / or stability of the mortar or concrete after application, to adjust the color, the handling, the implementation or the impermeability. The total content of additives ranges from 0.001% to 5% by weight based on the total mixture of the constituents of the mortar composition. The present invention also relates to a process for preparing the dry or paste mortar composition described above. According to one embodiment, the depolluting agent capable of trapping the aldehydes 3024138 5 is directly mixed with the binder, aggregates, aggregates, sands and / or fillers and any other additives during the preparation of the mortar composition. It is also possible to add the depolluting agent directly into an already prepared mortar composition comprising at least one binder, at least aggregates, aggregates, sands and / or fillers and any additives. This addition can be made before or at the time of mixing the mortar composition with water in the case of a dry composition. One of the advantages of the depolluting agent used in the mortar compositions according to the invention is in particular that it is in powder form, which allows it to be incorporated in the same way as other constituents of the composition. of mortar. The present invention also relates to an indoor floor, wall and / or ceiling coating obtained from a dry mortar composition tempered with water or a paste mortar composition and then cured. Such a coating contains between 5 and 50 g / m 2 of depolluting agent in the form of a powder capable of trapping the aldehydes and chosen from the amalgamated friends as described above. The coating according to the present invention makes it possible to absorb and consequently to depollute for several years a part in which it is deposited. Its operating time is therefore fully compatible with a usual use of an interior coating, since it is several years. The invention also relates to the use of such a coating to reduce the amount of aldehydes in the indoor air of a building. Very advantageously, the products obtained from the dry or paste mortar composition according to the present invention have no ammonia odor.
    [0007] The following examples illustrate the invention without limiting its scope. Example 1: Cement-based inner coating comprising tris (hydroxymethyl) -aminomethane trapping formaldehyde.
    [0008] 1% by weight of tris (hydroxymethyl) aminomethane is added to a commercially available cement-based interior under the name Weber.star. 220. The elimination performance of formaldehyde-type pollutants contained in a gaseous phase with this composition according to the invention are measured and are compared with an internal coating composition of the same type (Weber.Star 220) without any additive capable of trap formaldehyde. An empty test chamber without a coating sample was also tested as a calibration.
    [0009] The different samples are tested according to the method described in the ISD 16000-23 standard, with the following conditions and in three parallel test chambers: the pollutant is injected at the inlet of each of the chambers comprising each sample, a concentration of about 90 ppbv (parts per billion, by volume) -the relative humidity of the test chamber is 49% -the temperature of the test chamber is 23 ° C, -the air flow rate including the pollutant is 1.6 l / min, -the area of each sample is 0.2 m2 (each chamber comprises two pieces of 380 mm * 270 mm each) -the volume of the chamber is 28.2 I. Each test consists of placing each of the plaster samples in a chamber, to continuously send a stream of air polluted with formaldehyde through the chamber, so that the surface of the sample is swept away. continuous by a flow of polluted air and to measure at the exit of the chamber the Oncentration formaldehyde present in the air outgoing. The circulation of polluted air through the chamber is maintained for 320 hours. Figure 1 shows the evolution of the formaldehyde concentration in the air leaving the chamber as a function of time for the different samples tested. As expected, the air leaving the chamber without a coating sample (curve represented by triangular symbols) does not evolve over time: the formaldehyde concentration remains stable (about 90 ppbv).
    [0010] In the chamber comprising the Weber.star 220 interior coating, without any additive capable of trapping the pollutants (curve represented by the symbols in the form of squares), the concentration of formaldehyde increases regularly to reach the level of pollutant included in the air. entering after about 180 minutes. At the start of the test, the concentration of formaldehyde is relatively low (less than 20 ppbv) which can be explained by a physical absorption of the pollutant in the pores of the plaster matrix. On the other hand, it is noted that the concentration of formaldehyde remains stable and less than 5 ppbv throughout the test in the chamber which comprises the sample according to the present invention, that is to say the Weber.star 20 sample. 220 comprising 1% by weight of tris (hydroxymethyl) aminomethane (curve represented by the diamond-shaped symbols). The coating obtained from the mortar composition comprising the formaldehyde scavenger is therefore sufficiently reactive to remove all of the pollutant introduced throughout the test.
    [0011] EXAMPLE 2 Determination of the Formaldehyde Sorption Capacity of a Cement-Based Interior Coating Comprising 1% Formaldehyde Trapping Agent
    [0012] Tests have been carried out to determine the sorption capacity of an interior coating marketed under the name Weber. star 220, to which 1% by weight of tris (hydroxymethyl) aminomethane was added as described in ISD 16000-23.
    [0013] The cured coating was manually ground in a mortar and sieved. Fractions of 1 to 4 mm in size were placed in a glass tube with an inside diameter of 20 mm to fill 123 mm in the tube. The amount of material ground in the glass tube is 34.99 g. A stream of air polluted with formaldehyde is sent to the tube comprising the sample and in parallel in a control tube without sample, with a flow rate of 1.6 l / min. The concentration of formaldehyde in the air entering the tubes is about 2000 ppbv. The tests are carried out at a temperature of 23 ° C. The formaldehyde concentrations are measured in the flow of air exiting each of these tubes, continuously. Figure 2 shows the amount of formaldehyde absorbed as a function of time. The test was stopped after 240 hours (ie 10 days), while the maximum sorption capacity of the tested coating sample was still not reached. At the time of shutdown, the amount of coating introduced (34.99 g) had trapped 28.6 mg of formaldehyde. Therefore, 1 g of the coating according to the present invention, ie comprising 1% by weight of tris (hydroxymethyl) aminomethane can entrap at least 8.82 mg of formaldehyde. Example 3: Estimation of the long-term performance of a coating comprising 1% by weight of tris (hydroxymethyl) aminomethane From the tests carried out in Example 2 which make it possible to deduce that the sorption capacity is from less than 0.82 mg of formaldehyde per gram of coating, because 3 kg of plaster per m2 are used, parameters used in the AgBB control model (the abbreviation AgBB corresponding to "Ausschuss zur gesundheitlichen Bewertung von Bauprodukten "which is a German committee representing the German public health authorities in charge of vOC emissions in building materials), and considering a formaldehyde concentration at steady state of 50 pg / m3 (which means that there is permanently 1.5 mg of formaldehyde in the room), it can be determined that the coating in this room can trap the total amount of formaldehyde emitted for a period of at least 16 years. To carry out this calculation, the following data were used: formaldehyde sorption capacity of the coating: at least 0.82 mg per gram of plaster-coated surface: 43.4 m2 -consumption of coating: 3 kg / m2 - amount of coating in the room: 130.2 kg 10 - volume of the room: 30 m3 - air exchange rate exchanged in the room: 0.5 l / h 15 Example 4: Evaluation A plaster based interior coating comprising 30% by weight of Ca9D4 hemihydrate, 69% by weight of calcareous sand and 1% by weight of tris (hydroxymethyl) aminomethane or 1% by weight of acetoacetamide is used. Mixed with 25% by weight of water and applied to a thickness of 2 mm on a fiber cement sheet. A control sample without any scavenger and with the same plaster-based interior plaster is also prepared in the same way. The degree of discoloration (yellowness) is evaluated by measuring the L *, a *, b * colorimetric parameters with a Konica Minolta CM-3610d spectrophotometer (Illuminant D65 in the CIE Lab 1976 system) after storage indoors in ambient conditions for 1 day, 20 days and 40 days. As can be seen from Table 1 and Figure 3 which represents the evolution of the parameter b * as a function of time for the different samples tested, the color remains stable for the control sample which does not contain any agent. scavenger and for the sample that contains tris (hydroxymethyl) aminomethane. On the other hand, the sample which comprises 1% by weight of acetoacetamide as scavenger tends to yellow with time.

After 24 hours, the ammonia concentration in the air inside the desiccator is measured with Draeger 5 / a ammonia tubes, and with a Draeger Accuro pump. The measurements carried out showed that the desiccant air in which the sample comprising acetoacetamide as scavenger contained 40 ppm of ammonia. No trace of ammonia was detected in the air of the desiccator which contained the coating sample with the (hydroxymethyl) aminomethane hane. 20
