One-component adhesives for adhesive bonds having increased high-temperature strengths contain

Adhesives for adhesive bonds having increased high-temperature strength

Light-weight building boards which are based on mineral fibers and thermoplastic binders, may furthermore contain fillers, fireproofing agents and water repellents, contain, as the binder, from 4 to 20%, based on the weight of the mineral fibers, of polymers having a glass transition temperature of from 60.degree. to 110.degree. C., and consisting of not less than 60% by weight, based on the copolymer, of (meth)acrylates of alcohols of 1 to 4 carbon atoms and not more than 40% by weight of (meth)acrylonitrile and/or styrene, and additionally contain salts of polyvalent metals with carboxylic acids of 12 to 36 carbon atoms are distinguished by low water absorption and excellent sound-insulating characteristics, are flame-retardant and exhibit dimensional stability even in the tropics.

Layers of adhesives which are applied onto polyolefin surfaces from aqueous dispersion exhibit improved adhesion if a dicarboxylic acid dihydrazide of 2 to 10 carbon atoms and an aqueous dispersion of an adhesive polymer are applied, preferably as a mixture, onto the polyolefin surfaces which have been pretreated by corona discharge.

Sound-insulating boards which are based on mineral fibers and thermoplastic binders and may or may not additionally contain fillers, flameproofing agents and water repellants contain, as the binder, from 4 to 20%, based on the weight of the mineral fibers, of polymers having a glass transition temperature of from 30.degree. to 80.degree. C. and consisting of not less than 60% by weight, based on the copolymer, of (meth)acrylates of 1 to 4 carbon atoms and as much as 40% by weight of acrylonitrile and/or styrene.
