<p>PURPOSE: Provided is a polypropylene resin composition for interior surface material of automobile, which can be subjected to calender processing and high frequency welding. CONSTITUTION: The polypropylene resin composition comprises (A) 45-55 wt% of reactor type polypropylene resin which is a copolymer of propylene and C2 monomer or C4-C10 monomer; (B) 20-30 wt% of ethylene-glycidyl methacrylate-methylacrylate trimer; (C) 20-30 wt% of ethylene-vinyl acetate copolymer; and (D) 4-6 wt% of phthalate compound. The reactor type polypropylene resin(A) comprises 18-30 wt% of C2 monomer or C4-C10 monomer, and has melt index of 1 g/10 minutes(230 deg.C) or less. The ethylene-vinyl acetate copolymer comprises 20-30 wt% of vinyl acetate, and has melt index of 2-4 g/10 minutes(190 deg.C).</p> |
