FOAMING URETHANE COMPOSITE

摘要

FOAMING URETHANE COMPOSITION The invention relates to a foamed urethane composite comprising foamed urethane and a covering material which has good thermal aging-resistance. The composite is obtained by applying to the covering material surface to be contacted with the foaming urethane (A) an organic solvent solution or aqueous emulsion comprising (A-1) at least one of the following flexible urethane resins, starting materials for the preparation of flexible urethane resins and vinyl chloride resins; further applying thereto (B) an organic solvent solution comprising (B-1) a copolymer of a carboxyl group-containing ethylenically unsaturated monomer(s) with an acrylic and/or methacrylic acid ester(s) and (B-2) at least one of the following: blocked isocyanate compounds, poly-N-alkoxymethylmelamine compounds, polyepoxy compounds, polyoxazoline compounds, polydihydrooxazine compounds and reaetive polyamide compounds; and then subjecting the coated product to crosslinking under heating. The composite can be used advantageously for crash pads, armrests and the like in motorcars and airplanes and the like.
