Abstract

PURPOSE:To achieve prevention of a pad from being thermally deformed and improvement or the like of adhesion and sound insulation by a method wherein a thermoplastic resin sheet, a polymerized thermo-setting resin-impregnated antifreezing solution on its one side or both sides, and a polymerized insulation sheet on the one side in the same way are formed in a specific form. CONSTITUTION:A dash-panel pad 1 is composed of a thermoplastic resin sheet, for example, polyvinyl chloride sheet 2 (4.5kg/m<2>) in which barium sulfide and carbon black are mixed, a nonwoven fabric 2A fusion welded onto, for example, its rear face, and a poly-merized felt (an insulation sheet) 3 thereon. Further, the non-woven fabric 2A is impregnated with, for example, water-soluble melamine resin as a resin content at a tate of 40g/m<2>. Furthermore, respective through holes 1B-1D for a steering column, a brake pedal, an accelerator pedal, etc., are bored on the dash-panel pad 1. Then, the dash panel pad 1 is softened by heating, bent, and a dash panel of an automobile is coated therewith.
