PURPOSE:To obtain a surface skin material having flame-retardancy and odor- absorbing property and suitable as an inner trim for vehicle, etc., by dispersing a synthetic resin latex, active carbon, a clay mineral and a flame-retardant in an aqueous medium in the presence of a surfactant, foaming the obtained composition and applying the foamed composition to a substrate. CONSTITUTION:A synthetic resin composition is produced by dispersing (A) a polyurethane-based synthetic resin latex (containing 100 pts. wt. of solid component), (B) 50-200 pts. wt. (in terms of total solid content) of an actin carbon and a hydrated magnesium silicate clay mineral and (C) 100-200 pts.wt. (in terms of total solid content) of a flame-retardant composed of a brominated diaryl oxide and/or a brominated arene and antimony oxide in an aqueous medium in the presence of (D) a surfactant having a weight-average molecular weight of >=150 and <10,000 and a surfactant having a weight-average molecular weight of >=10,000. The obtained dispersion is mechanically foamed by introducing air into the composition with an oaks mixer, etc., applied to the surface of a substrate at a rate of 30-200g/m<2> in terms of solid content and dried to form the objective surface skin material. |
