Abstract
A sizing composition for insulating products based on mineral wool, in particular on glass or on rock, includes at least one monosaccharide and/or at lest one polysaccharide, and at least one organic polycarboxylic acid having a molar mass of less than or equal to 1000. Another subject-matter of the present invention is the insulating products based on mineral fibres thus obtained and the process for the manufacture thereof.
Claims42
A sizing composition for insulating products based on mineral wool, the composition comprising:
- at least one monosaccharide and/or at least one polysaccharide having a weight-average molar mass of less than 10000, and
- at least one non-polymeric organic polycarboxylic acid having a molar mass of less than 1000, wherein the at least one non-polymeric organic polycarboxylic acid represents at least 10% of a weight of the mixture composed of the at least one monosaccharide and/or the at least one polysaccharide and the at least one non-polymeric organic polycarboxylic acid.
A sizing composition for insulating products based on mineral wool, the composition comprising:
- a molasses, and
- at least one non-polymeric organic polycarboxylic acid having a molar mass of less than 1000,
- wherein the molasses comprises from 40 to 60% by weight of glucides, and wherein the at least one non-polymeric organic polycarboxylic acid represents at least 10% of a weight of the mixture composed of the molasses and the at least one non-polymeric organic polycarboxylic acid.
A sizing composition for insulating products based on mineral wool, the composition comprising:
- at least one monosaccharide and/or at least one polysaccharide having a weight-average molar mass of less than 10000, and
- at least one non-polymeric organic polycarboxylic acid having a molar mass of less than or equal to 750,
- wherein the at least one non-polymeric organic polycarboxylic acid represents at least 10% of a weight of the mixture composed of the at least one monosaccharide and/or the at least one polysaccharide and the at least one non-polymeric organic polycarboxylic acid.
