Abstract:
1. A vehicle interior material comprising a substrate of the vehicle interior material and a coating composition coated thereon comprising a synthetic resin emulsion and at least one non-halogen flame retardant in which phosphorus and nitrogen-containing non-halogen flame retardant particles are surface coated with a functional group-containing organosilicon resin, said synthetic resin emulsion being selected from the group consisting of (meth)acrylate resin base emulsions, styrene/acrylate copolymer base emulsions, ethylene/vinyl acetate copolymer base emulsions and mixtures thereof, said phosphorus and nitrogen-containing non-halogen flame retardant particle being at least one selected from the group consisting of guanidine phosphates, ammonium phosphates, and ammonium polyphosphates, said functional group-containing organosilicon resin being the reaction product of a siloxane oligomer which is a partial hydrolytic condensate of at least one alkoxysilane having the formula: wherein R is a monovalent hydrocarbon group, R′ is C 1 -C 4 alkyl, and n is an integer of 0 to 3, the condensate containing at least one alkoxy group and having 2 to 10 silicon atoms on the average, with a functional group-containing organosilicon compound which is a functional group-containing alkoxysilane having the formula: wherein X is an alkyl group having a functional group selected from the group consisting of epoxy, vinyl, mercapto, carboxyl, and amino, R is a monovalent hydrocarbon group, R′ is C 1 -C 4 alkyl, m is 1, 2, or 3, k is 0, 1, or 2, and m+k is 1, 2, or 3, or a partial hydrolyzate thereof, wherein 0.1 to 20 parts by weight of a bis(alkoxysilyl) group-containing compound or partial hydrolyzate thereof is added per 100 parts by weight of the siloxane oligomer, and said at least one non-halogen flame retardant being added in an amount of 1 to 300 parts by weight per 100 parts by weight of solids of the synthetic resin emulsion.
