1. A sizing composition for insulating products based on mineral wool, the sizing composition consisting of:
at least one saccharide, at least one organic polycarboxylic acid having a molar mass of less than or equal to 1000,
wherein the polycarboxylic acid is a non-polymeric polycarboxylic acid selected from: (1) a dicarboxylic acid selected from the group consisting of oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, malic acid, tartaric acid, tartronic acid, aspartic acid, glutamic acid, fumaric acid, itaconic acid, maleic acid, traumatic acid, camphoric acid, optionally substituted phthalic acid, optionally substituted tetrahydrophthalic acid, isophthalic acid, terephthalic acid, mesaconic acid and citraconic acid;
wherein optionally substituted phthalic acid comprises at least one boron or chlorine atom and optionally substituted tetrahydrophthalic acid comprises at least one chlorine atom; (2) a dicarboxylic acid precursor selected from the group consisting of maleic anhydride, succinic anhydride and phthalic anhydride; (3) a tricarboxylic acid selected from the group consisting of citric acid, tricarballylic acid, 1,2,4-butanetricarboxylic acid, aconitic acid, hemimellitic acid, trimellitic acid and trimesic acid; or (4) a tetracarboxylic acid selected from the group consisting of 1,2,3,4-butanetetracarboxylic acid and pyromellitic acid;
wherein the non-polymeric polycarboxylic acid is present in an amount of at least 10% of the weight of the mixture of the saccharide plus the at least one polycarboxylic acid at least one reactive silicone; a catalyst chosen from Lewis acids and bases, phosphorus-containing compounds and compounds comprising fluorine and boron; wherein the catalyst is present up to 20% of the weight of the saccharide and organic polycarboxylic acid; additives, calculated on the basis of 100 parts by weight of saccharide and organic polycarboxylic acid: from 0 to 2 parts of silane, from 0 to 20 parts of oil, from 0 to 30 parts of urea and/or of glycerol, from 0 to 30 parts of an extender chosen from lignin derivatives, and animal or plant proteins; and water. |
