Abstract
A sizing composition for insulating products based on mineral wool, in particular on glass or on rock, includes: at least one saccharide, at least one organic polycarboxylic acid having a molar mass of less than or equal to 1000, and at least one reactive silicone. Furthermore, insulating products based on mineral fibres thus obtained and the process for the manufacture thereof are presented.
Claims25
A sizing composition for insulating products based on mineral wool, in particular on rock or glass, the sizing composition comprising:
- at least one saccharide,
- at least one organic polycarboxylic acid having a molar mass of less than or equal to 1000, and
- at least one reactive silicone.
A process for the manufacture of an acoustic and/or thermal insulating product based on mineral wool or of a veil of mineral fibers, the process comprising:
- projecting a sizing composition onto said wool or said fibres, and treating said wool or said fibres at a temperature permitting the crosslinking of the size and the formation of an infusible binder, wherein the sizing composition comprises:
- at least one saccharide,
- at least one organic polycarboxylic acid having a molar mass of less than 1000, and
- at least one reactive silicone.
