Abstract

1369285 Laminates AMERICAN CYANAMID CO 10 March 1972 11417/72 Heading B5N A laminate having sound and vibration damping properties comprises a perforated polymeric layer having an open area of 5-95% having bonded to at least one surface thereof a metal layer by means of an elastomeric adhesive having embedded therein a woven stressraising member, the perforations in the polymeric layer being devoid of adhesives or containing only minor amounts of adhesive. The woven stess-raising member which may be made from polyvinylidene chloride, polyacrylonitrile, poly-(methyl methacrylate), paper, neoprenecoated paper, asbestos, glass or polymer-coated fibreglass may be a fabric or network of cords, ribbons or wires that cross at regular intervals and may or may not be secured at the crossings and may be in the form of a braid, reticulation, mesh, net, sieve or screen interlaced, intertwined, tangled or otherwise intertwisted. The metal layer may be of steel, zinc, gold, aluminium, copper, magnesium, brass, titanium, lead, nickel or silver. The perforations in the polymer layer which may be circular, oval, rectangular, diamond or random shaped may be produced by percussion, punching, moulding, drilling or casting. The adhesive is preferably a polyurethane which may also contain a diamine curing agent, a glycidyl ether or ester, an aminosilane, an epoxy silane and a polyethylenically unsaturated compound.
