Abstract
The present invention relates to an aqueous sizing composition for insulating products based on mineral wool, comprising (a) at least one carbohydrate chosen from reducing sugars, hydrogenated sugars and a mixture thereof, (b) at least one polycarboxylic acid or a salt or anhydride of such an acid, (c) from 1% to 25% by weight, relative to the sum of components (a) and (b), of at least one aliphatic, cycloaliphatic or aromatic monoalcohol free of acid or base functions and having an octanol/water partition coefficient (Log Kow) of between 1 and 3.
Claims21
An aqueous sizing composition for mineral wool-based insulating products, the composition comprising:
- (a) at least one carbohydrate selected from the group consisting of hydrogenated sugars, reducing sugars, non-reducing sugars and mixtures thereof;
- (b) at least one polycarboxylic acid or a salt or anhydride thereon;
- and
- (c) from 1% to 25% by weight, relative to the sum of the components (a) and (b), of at least one aliphatic, cycloaliphatic or aromatic monoalcohol free of acid or base functions and having an octanol/water partition coefficient Lop Kow of between 1 and 3,
- wherein the aliphatic monoalcohol is at least one selected from the group consisting of 1-pentanol, 3-methyl-1-butanol 2,2-dimethyl-1-propanol, 2-pentanol, 3-pentanol, 3-methyl-2-butanol, 2-methyl-2-butanol, 2-ethyl-2-propanol, 1-hexanol, 2-hexanol, 3-hexanol, 3,3-dimethyl-2-butanol, 1-heptanol, 2-heptanol, 3-heptanol, 4-heptanol, 1-octanol, 2-octanol, and 4-octanol.
An aqueous sizing composition for mineral wool-based insulating products, the composition comprising:
- (a) at least one carbohydrate selected from the group consisting of hydrogenated sugars, reducing sugars, non-reducing sugars and mixtures thereof;
- (b) at least one polycarboxylic acid or a salt or anhydride thereof;
- and
- (c) from 1% to 25% by weight, relative to the sum of the components (a) and (b), of at least one aliphatic, cycloaliphatic or aromatic monoalcohol free of acid or base functions and having an octanol/water partition coefficient Log Kow of between 1.05 and 2.0.
