USE OF GLYCEROL AS AN ADDITIVE FOR AQUEOUS GLUES DEVOID OF FORMALDEHYDE

摘要

The invention relates to the use of glycerol as an additive for aqueous glues which are devoid of formaldehyde and based on acrylic polymer or acrylate, used for the production of mineral-wool based products, in order to improve the resistance to ageing of said mineral-wool based products obtained after the cross-linking of said glue. The products which are based on mineral-wool which is bound with said environmentally friendly glue have the same quality as products which are bound in a conventional manner with phenolic resin. Modifications in the thickness and the flexibility of the products obtained are improved. .
