    [0001] The present invention relates to a plant-based binder based on modified pitch of tall oil (tall oil), modified plant resin and, if appropriate, a plant-based binder. oil. The invention also relates to waterproofing membrane, sound-absorbing membrane, liquid sealing system, bituminous coating, asphalt coating, primer, varnish, putty, glue or coating compositions. binder emulsion which comprises said binder and a method for decreasing the amount of petroleum bitumen in said compositions. Bitumen of petroleum origin is frequently used to make waterproofing membranes, especially for sealing roofs, or road surfaces. It has in fact viscoelastic properties and waterproofing interesting while having a low cost and good stability over time. A conventional bituminous composition for producing a waterproofing membrane comprises in particular: 35 to 87% of bitumen; - 3 to 15% of polymer; - 10 to 50% charge; - 0.1 to 5% of additives; Said composition being coated on a fibrous support, for example by coating and calendering, to produce a prefabricated waterproofing membrane which can be used in particular to seal the roofs. A conventional composition for producing a road surface comprises in particular: 1 to 10% of bitumen; 30 - 80 to 98% of charges; said bitumen may be a modified bitumen, that is to say a bitumen comprising at least one polymer. The polymer content in the modified bitumen is conventionally from 0.5 to 6% by weight of polymer relative to the total weight of the bitumen and the polymer. Bitumen of petroleum origin is a mixture of hydrocarbons obtained after distillation of the oil. This bitumen, in a pasty or solid form, is hot liquefiable and strongly adheres to the substrates to which it is applied. Since oil is a non-renewable fossil resource, it would be desirable, from a sustainable development standpoint, to replace oil-based bitumen with a plant-based binder, especially as the growing global demand for gasoline Petroleum products have reduced the quality and availability of oil-based bitumen. US Patent Application 2012/0041117 of S.A. Imperbel N.V. describes a binder of natural origin comprising: - 14 to 19% by weight of natural oil; - 4 to 17% by weight of polymer; - 32 to 40% of resin. US patent application 2012/0071597 to S.A. Imperbel N.V. describes a binder of natural origin comprising: - 1 to 65% by weight of a pitch of crude tall oil; - 7 to 40% by weight of polymer; - a charge. The binders of these two patent applications can in particular be used to make waterproofing membranes for roofs. However, the membranes obtained with said binders are unsatisfactory because they exhibit very significant degradation of thermomechanical properties after aging. These mixtures also have an exaggerated water intake. Patent application EP 04300190.8 of Colas SA also discloses a plant-based binder for the production of materials for buildings and / or public works which comprises, relative to the total weight of the binder: (a) 2 at 98% by weight of at least one natural or modified natural resin of plant origin having a softening temperature of 30 to 200 ° C; (b) 98 to 2% by weight of at least one vegetable oil having a viscosity at 25 ° C of from 50 mPa.s to 1000 Pa.s; (c) said binder having: (c) a penetration at 25 ° C of 20 to 300 1 / 10mm and a softening temperature of 30 to 75 ° C; (c2) a penetrability at 15 ° C of 300 to 900 1/10 mm and a viscosity at 60 ° C of 2 to 20 Pa; and (d) said binder being free of any natural or synthetic elastomer and any thermoplastic polymer. However, the binder of this application is not suitable for modification by polymers. After much research, the Applicants have developed a binder of plant origin that can be used as a replacement for part or all of the bitumen of petroleum origin in a composition for making membranes or coatings such as in particular a waterproofing membrane, a sound-absorbing membrane, a liquid sealing system, a bituminous asphalt coating, an asphalt coating, a primer, a varnish, a putty, an adhesive or a binder emulsion.

Plasticizing Fraction The plasticizing fraction of the binder of the present invention comprises a modified tall oil pitch.
    [0003] Tall oil pitch is a by-product of Kraft pulp manufacturing. Thus, when coniferous wood chips are treated with a mixture of sodium hydroxide and hot sodium sulphide, the lignin and hemicellulose degrade and dissolve in the liquor while the cellulose can be recovered in form. of pulp and then washed. The liquor, which also contains acids in the form of sodium carboxylates, is recovered and concentrated. The foam that forms on the surface of the concentrated liquor is recovered and then acidified hot with sulfuric acid to yield tall oil crude. The tall oil crude is then distilled at reduced pressure and the residual non-volatile fraction is the pitch of tall oil. The pitch of tall oil, referenced under CAS No. [8016-81-7], mainly comprises fatty acids such as palmitic acid, linoleic acid and oleic acid; fatty acid esters; resin acids such as abietic acid and its isomers, pimaric acid, isopimaric acid and sandaracopimaric acid; rosin acid esters; diterpenic alcohols; fatty alcohols and sterols.

In a preferred embodiment, it eliminates all bitumen of petroleum origin. The invention will be described in more detail with the aid of the following examples which are given purely by way of illustration. EXAMPLES In the description and examples below, the following methods were used. Ring Ball Temperature (TBA) or softening temperature The TBA (or softening temperature) is measured according to standard NF EN 1427, June 2007. The material to be tested is placed in copper rings. The rings are placed in a TBAmeter. A metal ball is placed on the surface of the rings which are heated until the ball passes through the ring. The temperature at which the ball passes through is the TBA. Penetration at 25 ° C (penetrability) Penetration is measured according to standard NF EN 1426, December 20, 1999. The material to be tested is stored at 25 ° C. and penetration into the needle penetrometer is measured with a penetrometer. sample, after a period of 5 seconds, a needle diameter at the tip of 0.14 to 0.16 mm whose weight with its support is 100 g. The penetrability is expressed in tenths of a millimeter. Foldability or cold flexibility The pliability is measured according to standard NF EN 1109, 1999. A specimen having a thickness of 2 mm is formed with a film puller. The susceptibility to cracking of the specimen is determined by folding at low temperatures. The lower temperature at which the test specimen can be folded around a 30 mm diameter mandrel is thus sought. Elastic stretching or remanence This is the ability of a mixture to regain its original size after undergoing elongation followed by relaxation. Remanence is the residual deformation after relaxation. A specimen having a thickness of 2 mm is formed with a film puller. Said specimen is subjected to a given elongation for 24 hours.
    [0037] The test piece is then placed on an anti-adherent support for 24 hours. For a mixture that has not undergone any aging step, the elongation is set at 200% for 24 hours. For an accelerated aging mixture for 6 months at 70 ° C elongation is set at 25% for 24 hours. Water intake The water intake is measured as follows. A specimen having a thickness of 2 mm is formed with a film puller. Said test piece is immersed in water.
    [0038] Regularly, for example every 2 weeks, the test tube is removed from the water, dried and weighed. The initial weight is compared before immersion and after immersion. The mass difference is attributed to a water uptake of the specimen. The test piece is returned to water and this test is repeated until the mass of the immersed test piece is stabilized. This test is performed at room temperature. In the examples below, the following commercial products and acronyms were used: Resinoline DP1202: tall oil pitch triethylene glycol ester having a residual acidity corresponding to an acid value of 10 mg KOH per unit product and available from DRT. Dertophene DP1104: modified phenolic terpene-type plant resin, said resin having a softening temperature of 140 ° C, residual acidity corresponding to an acid number of less than 1 mg KOH per gram of product and available from the company DRT. Granolite DP 1105: fortified rosin-ester modified plant resin comprising fortified rosin modified by esterification reaction with pentaerythritol, said resin having a softening temperature of 140 ° C., a residual acidity corresponding to an index of acid of 45 mg of KOH per 15 grams of product and available from the company DRT. RADIA 7396: saturated polyester oil marketed by OLEON. RADIA 7380: saturated polyester oil based on trimethylolpropane triisostearate marketed by OLEON. Kraton® 1186: styrene-butadiene-styrene block copolymer sold by Kraton. BL200: calcium carbonate having a particle size of between 8 and 200 micrometers.
