AN AUTOMOBILE INTERIOR HEADLINER MOLDING OR FORMING MEMBER AND AN AUTOMOBILE INTERIOR HEADLINER MEMBER USING THE SAME

摘要

The problem to be solved is to provide an automobile interior headliner member which is improved in the film forming property of a complex plastic material used as a base material of the automobile interior headliner member, and has high rigidity and excellent heat resistance, size stability and working efficiency upon attachment; and the base material. An automobile interior headliner molding or forming member which is obtained by kneading mica having a particle size of 10 to 100 mu m with a polypropylene resin having a melt flow rate at 230 DEG C of 3 to 40 g/10 min to obtain the corresponding resin having a mica content of 15 to 40 wt.%, molding or forming the resin into a mica-containing polypropylene sheet of 100 to 300 mu m thick and then stacking this sheet over each of both sides of an expanded polypropylene sheet of 2 to 6 mm thick obtained at an expansion ratio of 5 to 50 times; and an automobile interior headliner member molded or formed from the molding or forming member.
