BINDER FOR MINERAL FIBERS

摘要

An aqueous binder composition for mineral fiberss comprises a water-soluble binder component obtainable by reacting glycerol and at least one alkanolamine with at least one carboxylic anhydride in proportions such that the ratio of equivalents of amine groups plus hydroxy groups (NH+OH) to equivalents of carboxy groups (COOH) in the binder component is within the range of about 0.4 to 2.0, glycerol being used in an amount such that the equivalent ratio of glycerol OH groups to total equivalents of amine groups plus hydroxy groups (NH+OH) is 0.1 to 0.9, and, optionally, treating the reaction product with a base.
