Hydrogenated sugar-based sizing composition for bonding mineral or natural organic fibers

Abstract

The present invention relates to a sizing composition for bonding mineral fibers or natural organic fibers, characterized in that it comprises: - at least one hydrogenated sugar, - at least one polycarboxylic organic acid, - at least one salt of a hydroxylated carboxylic acid: of general formula (I): HO−(C)R1R2−(CH2)n−COOX, or of general formula (II): (HO−(C)R1R2−(CH2)n−COO)2Y, in which R1 is a hydrogen atom, or a methyl group CH3, or an alkyl group of formula (A): –(CH2)p−CH3, where p is an integer between 0 and 6, and R2 is a hydrogen atom, or a methyl group CH3, or an alkyl group of formula (A): –(CH2)p−CH3, where p is an integer between 0 and 6. and 6, and n is an integer between 0 and 2, and X is an element chosen from sodium, potassium and lithium, and Y is an element chosen from calcium, magnesium, beryllium and zinc.The present invention also relates to the method of manufacturing an insulation product comprising mineral fibers or natural organic fibers which uses the aforementioned gluing composition, as well as an insulation product that can be obtained by such a method.
