EMULSION COMPOSITION FOR ADHESION AND METHOD FOR BONDING FIBER SUBSTRATE TO SILICONE RUBBER SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide an emulsion composition for adhesion which is used for bonding a fabric substrate to a silicone rubber substrate, can be well applied to a fabric substrate, and is excellent in adhesive properties. SOLUTION: The first emulsion composition for adhesion contains (A1) 100 pts.wt. silane having at least one epoxy group at the molecular chain end and/or its partial hydrolyzate, (B) 20-500 pts.wt. water-dispersible silica, (C) 20-1,500 pts.wt. emulsion or water dispersion of a urethane resin, and (D) water. The second emulsion composition contains (A2) 100 pts.wt. silane having at least one methacryloxypropyl group at the molecular chain end and/or its partial hydrolyzate, (B) 20-500 pts.wt. water-dispersible silica, (C) 20-1,500 pts.wt. emulsion or water dispersion of a urethane resin, and (D) water.
