专利说明:

[0001] The invention relates to a polyester resin of linear or branched structure and free of unsaturated fatty acids, which is hydroxylated or carboxylated based on renewable raw materials, in particular at least based on specific biosourced polyol, a coating composition. comprising said resin and its use in coatings having high durability and based on renewable raw materials, in particular for coatings of metal foils. Oil-free functionalized polyester resins are well known for coils applications known as coils.
[0002] Polyester resins polyols based on renewable origin components also known as "biobased" for application in metal foil coatings are already described in WO 2012/042153 and in particular resins without oil. These polyester resins are based on rosin. However, as such, they need improvement in terms of durability and resistance to yellowing.
[0003] BA Noordover et al describes in J. Biomacromolecules, 2006, 7, 3406-3416 co- and terpolyesters based on isosorbide and succinic acid and other monomers of renewable origin such as 2,3 butanediol or 1, 3 propanediol or citric acid. No presence of polyacids longer chain in at least Cg is mentioned or suggested.
[0004] The present invention seeks to develop new hydroxylated or carboxylated polyester resins, without oil and free of any unsaturated fatty acid residue having improved durability and yellowing resistance and compromise toughness / flexibility while having a good chemical resistance, in particular to organic solvents and water, concerning the coating obtained, in particular for application on metal sheets. The first object of the present invention relates to said linear or branched polyester resin which is hydroxyl and / or carboxyl based on a specific composition with renewable raw materials and in particular based on a specific biosourced polyol.
[0005] Also covered is the solution of said resin in an organic solvent. Another object of the invention relates to a coating composition comprising said resin and in particular a crosslinkable coating composition. Also part of the invention is the use of said resin in said coating compositions and finally the resulting coating. Therefore, the first subject of the invention relates to a polyester resin of linear or branched structure and free of unsaturated fatty acids, which is hydroxylated or carboxylated, optionally hydroxylated and carboxylated, which resin is based on: a component acid comprising: al) at least one C4 to C6 polycarboxylic acid or carboxylic anhydride, preferably having a functionality ranging from 2 to 4, more preferably equal to 2 to 2), at least one C 8 to C 64 carboxylic polyacid or anhydride, preferably of fat functionality ranging from 2 to 4, more preferably equal to 2 to 3) optionally at least one monoacid saturated with 02 to 022, optionally capable of carrying a hydroxyl group an alcohol component comprising: 131) at least one biosourced polyol of functional fbl at least 2, preferably 2, carrying a 1,4: 3,6 dianhydrohexitol unit and at least one of the following two polyols b2) or b3): b2) at least one different polyol 131) and of functionality fb2 of at least 2, preferably 2, more particularly a C3 to 036 b3 polyol) at least one polyol other than 131) and b2) of functionality fb3 of at least 3, preferably 3. According to one particular option, the two polyols b2) and b3) may be present.
[0006] The term "unsaturated fatty acid-free resin" means, in accordance with the present invention, the absence of any unsaturated fatty acid or unsaturated fatty acid oil in chemically incorporated form in the structure of said resin or in free form. (not chemically incorporated). Said polyacid al) includes in its cover acids such as aconitic acid derived from sugarcane, C6 and functional fai = 3. The polyacid al) may also carry a hydroxyl group such as citric acid with = 3 and carrier in addition to a hydroxyl or malic function with fai = 2 and carrying a hydroxyl or glutamic acid with fai = 2 and carrying an amine group. More particularly, said unit carried by said polyol 131) is isosorbide (1,4: 3,6 dianhydro-D-sorbitol), isomannide (1,4: 3,6 dianhydro-D-mannitol) or isoidide (1,4: 3,6 dianhydro-L-iditol). According to a particular preference, a fraction of at least 50%, preferably at least 75% by weight of said resin is biosourced. A resin or biobased product means that it comprises a raw material of non-fossil origin that is renewable and of vegetable or animal origin. The "biobased" characteristic of a product or resin or raw material used as a component of said product, such as a polyacid, a polyol or a fatty acid can be determined by determining the carbon content of the product. which attests the renewable origin of the carbon of said component as such or incorporated into a final product after reaction (which in no way modifies this rate). Indeed, a biobased component is a component in which the carbon comes from carbon dioxide (002) fixed by photosynthesis from the Earth's atmosphere. The specific fixed content of carbon 14C is the signature of a biobased component which is different from that corresponding to a component of fossil origin. This content can be determined according to ASTM D 6866 (ASTM D 6866-06) or ASTM D 7026 (ASTM D 7026-04), in particular by mass spectrometry according to ASTM D6866-06. In a particular case, said component b) comprises b2) and b3) and at least 50% by weight, preferably at least 75% by weight of said component b) is bio-sourced. More particularly, components a) and b) can be 100% biobased.
[0007] According to another particular option, said polyol b2) is bio-sourced and chosen from 1,3 propylene diol or 1,2 propylene diol, 1,4 butanediol or diols based (meaning derived) from saturated fatty acids. . Such diols may have a chain at 0-12 to 036. Still more particularly, said polyol b3) may be bio-sourced and selected from glycerol and its ether-polyol derivatives, such as polyglycerols (oligomeric derivatives of glycerol). In the case where the functionality of one of the components mentioned is greater than 2, preferably the number-average functionality of the mixture of components a) + b) does not exceed 2. Said polyester is therefore of linear or branched structure and by definition it can not include a crosslinked structure, which is thus excluded by definition. Those skilled in the art know in particular to choose the proportions and the functionalities of reactive components as well as the conversion rate of the reactive functions, in order to avoid any crosslinking or chemical gelling of the reactive system. This question can only arise when one of the reactive components (a) and (b) has an average functionality greater than 2 to obtain a branched structure. It is possible to control the structure without any possible crosslinking, by adjusting the proportions of the components a) and b) so that the number average functionality (per mole of reactant component) over all the reactive components (a + b ) does not exceed 2 or if it exceeds 2 to limit the conversion rate well before the gel point (gelling) predictable either by experimentation or by calculation according to the Macosko-Miller relationship and / or by progressive addition of component the least functionalized on the most functionalized component with efficient stirring (maintained in excess of reactive functions by the progressive addition of the second reactive component). The Macosko-Miller relationship cited above is as defined by Macromolecules, vol. 9, pp. 199-211 (1976) and is considered well known to those skilled in the art. For clarity, we recall below this relation which links the critical ratio I-, reactive functions for two reactive components A and B at the gel point, I-, = functions of A / functions B, with the functionality average of A which is fA, and that of B which is fB with the critical conversion rate at the following gelling point xg: rc * x92 = 1 / [(fB -1) * (fA-1) 1 Said polyacid al) may be in particular a biosourced aliphatic diacid selected from: succinic acid, tartaric acid, citric acid, malic acid or itaconic acid, glutaric acid, glutamic acid, fumaric acid, furan dicarboxylic acid, tetrahydrofuran 2,5 dicarboxylic acid and tetrahydrofuran acid 3 Dicarboxylic acid and preferably: succinic acid, itaconic acid, glutamic acid, fumaric acid, furan dicarboxylic acid, tetrahydrofuran 2,5 dicarboxylic acid and tetrahydrofuran 3,5 dicarboxylic acid. Said polyacid a2) may also be bio-sourced and chosen from: azelaic acid (Ce), sebacic acid (Cie), undecanedioic acid, dodecane dioic acid or dimers and trimers of fatty acids respectively in 036 and 054. The presence of this diacid a2) and its proportion with respect to al) are important factors for playing on the hardness / flexibility compromise of the final coating and adjusting the hardness / flexibility ratio, increasing the a2) ratio improves the flexibility. Conversely, the hardness of the coating increases with the rate of al). Preferably, the molar ratio a1) / a2) varies from 2 to 8 and more preferably from 3 to 7.
[0008] According to a particular embodiment, said monoacid a3) is present in the composition of said resin and selected from: acetic acid, pyruvic acid, lactic acid or rosin (abietic acid and C20 isomers) or an acid saturated fat in 012 to 022. According to a particular and preferred embodiment of said resin, said polyol 131) represents at least 30% by weight of said resin, this weight of "said resin" meaning here "with respect to the total weight of the components a) + b) used for said resin ". More particularly, the level of polyol 131) in% mol / mol over the entire alcohol component b) ranges from 40 to 80 and preferably from 55 to 65. The level corresponding to polyol b2) can vary from 0 to 50 and preferably from 25 to 35.
[0009] The molar ratio of the polyol b3) can vary from 0 to 20 and preferably from 5 to 15. With regard to the OH or carboxy, optionally OH and carboxy functionality of said resin, it can correspond to an OH number and / or acid ranging from 10 to 200 mg KOH / g. More particularly, said resin may have a carboxy functionality corresponding to an acid number of less than 20, preferably less than 10 and more preferably less than 5 and in particular 0 mg KOH / g and an OH functionality corresponding to an index. OH ranging from 10 to 200, preferably from 10 to 150 mg, more preferably from 10 to 100 KOH / g. The OH number is determined according to ISO 2554. The acid number is determined according to ISO 2114.
[0010] The resin according to the invention can therefore be functionalized OH or carboxy or OH and carboxy, preferably in the latter case with a predominant OH functionality, that is to say more than 90% of functional groups being OH. As regards the number-average molecular mass Mn of said resin, it may vary from 500 to 20000 and preferably from 750 to 10000. This molecular weight Mn 15 is determined by calculation from the functional index (in mg KOH / g ) and the average functionality fr of said resin which represents the average number of OH and / or carboxylic acid functions, calculated from the material balance (molar proportions) and the known functionality of components a) and b) used. The Tg of said resin may vary from -10 ° C to 100 ° C and preferably from 10 to 50 ° C.
[0011] Said Tg is determined by DSC measurement with 2 passes at 10 ° C / min. The second subject of the invention relates to a solution of resin in an organic solvent, which solution comprises at least one resin as defined above according to the invention. More particularly, said solvent may be selected from methyl esters or ethyl esters of C2-C4 monocarboxylic acids or esters of said monocarboxylic acids with methoxy or ethoxy monoethers of C2-C4 diols, in particular propyl methoxy acetate. or from methyl or ethyl diesters of C4 to C6 dicarboxylic diacids, terpenes, polyhydroxyalkanoates, methyl or ethyl esters of fatty acid oils or lactic acid esters with C1 to Cs alcohols.
[0012] The resin of the invention may be prepared by reaction between the acid components a) and alcohol b) as defined above and in the following successive steps: i) reaction of the whole acid component a) with said component b1 ) of said alcohol component b) up to a conversion of at least 85%, preferably 100% of said component b1), followed by ii) reaction of the product from step i) with the remainder of said alcohol component b) , comprising at least one of polyols b2) or b3) as defined above, the reactions of said steps i) and ii) taking place in solution in at least one organic solvent which can form an azeotrope with water. The carboxy / OH ratio in the first step i) can vary from 1.1 to 2.1, preferably from 1.2 to 2.
[0013] The functionality of said resin is regulated by the nature of component a) or b) being in stoichiometric overall excess. A third object of the invention relates to a coating composition, preferably a coating composition in organic solvent medium, which composition comprises at least one resin as defined above according to the invention or (comprises) a resin solution as defined above. Preferably, said composition is a crosslinkable composition comprising in addition to said resin at least one crosslinking agent bearing reactive groups with the hydroxyl groups and / or carboxyls carried by said resin. When said resin is hydroxylated, said crosslinking agent may be selected from: melamine or polyisocyanate, in particular blocked polyisocyanate or polyanhydride or polysilane, in particular alkoxy-blocked polysilane and when said resin is carboxylated, said crosslinking agent may be selected from polyepoxides or polyols. Suitable crosslinking polyols when said resin is carboxylated include all monomeric or oligomeric polyols of aliphatic or cycloaliphatic structure. Examples of aliphatic monomeric polyols that may be mentioned include trimethylol propane or glycerol or pentaerythritol or ditrimethylolpropane or dipentaerythritol, these polyols possibly being alkoxylated. Other suitable polyols are acrylic polyol oligomers, polyether polyols or polyester polyols. Polyester polyester oligomers which are suitable as crosslinking agents when said resin is carboxylated are also hydroxylated polyester resins as defined according to the present invention. More particularly, said coating composition is fully biosourced with said resin and said crosslinking agent being both biosourced, preferably 100% biobased. In the possible case where the resin carries both hydroxyl and carboxy functions, a mixture of crosslinking agents corresponding respectively to each functionality of said resin can be used and optionally with two addition steps to avoid possible coreaction between the two. crosslinking agents. Preferably, the OH or carboxy functionality is predominant or unique and said crosslinking agent is specific for OH functionality only or specific for carboxy functionality only. According to a particularly preferred option, said composition is a coating composition in an organic solvent medium and in particular a paint or varnish composition, more particularly for metal surfaces. More preferably, said metal surfaces are in the form of metal sheets (in English "coils"). Another subject of the invention relates to the use of a resin as defined above or the use of a solution of such a resin in coating compositions, in particular in coating compositions. crosslinkable. Such a use relates in particular to "one-component" behavior of coating compositions for metal and in particular for metal foil coating. A composition with a "one-component" behavior is characterized by the fact that it is stable in storage and can only be crosslinked by thermal activation, a characteristic which is indispensable for this purpose. According to one particular option, said use relates to a primary coating, a finish, a tape backing or a monolayer coating. The term "tape backing" here means a coating applied to the "back" or "hidden" side of the metal foil (tape).
[0014] Another potential use of said resin is for powder coatings, in particular crosslinkable coatings. Said resin may be carboxylated and the crosslinking agent may be a polyepoxide or a polyol based on cyanurate, in particular trihydroxyethyl cyanurate. According to another option, said use relates to "two-component" coatings. The two-component coating compositions are crosslinkable at low temperature and without the need for thermal activation. In fact, in this case, said resin in the presence of said crosslinking agent reacts immediately mixed with said agent. Therefore, such a composition is prepared just prior to use and is therefore not storage stable, resulting after mixing and reaction of said resin with said crosslinking agent, with an irreversibly crosslinked structure. Finally, the invention relates to a finished product, in particular a coating, which results from the use of at least one resin as defined above or from a solution of such resin or a coating composition such as defined above according to the present invention.
