Abstract:
The present invention relates to a polypropylene resin composition for automobile interior covering methods capable of calender molding and high frequency welding. More particularly, the present invention relates to the polypropylene resin composition capable of calender molding and high frequency welding, which the same comprises a reactor-type polypropylene resin with excellent melt tension, an ethylene-vinyl acetate copolymer having polarity, an ethylene-glycidyl methacrylate-methyl acrylate terpolymer and a phthalate and thus useful for the automobile interior covering materials.
Abstract:
PURPOSE: A thermoplastic resin composition for a plastic sheet, its preparation method and a plastic sheet prepared by using the composition are provided, to improve the working range in rolling and the vacuum molding. CONSTITUTION: The composition comprises 15-80 wt% of a highly crosslinked polypropylene-based resin; 3-30 wt% of a partially crosslinked polypropylene-based resin; 3-30 wt% of a reactive polypropylene resin; 1-20 wt% of a highly crosslinked thermoplastic olefin resin; 1-30 wt% of a polypropylene homopolymer resin; 1-30 wt% of a branched polypropylene resin; and 3-50 wt% of a linear low density polyethylene resin. Preferably the partially crosslinked polypropylene-based resin is a copolymer of ethylene and propylene and has a melting index of 0.1-2 g/10 min (230 deg.C, 2,160 g); the branched polypropylene resin is a high melt strength polypropylene resin and has a melting index of 1 g/10 min (230 deg.C, 2,160 g); and the linear low density polyethylene is a copolymer or ethylene and a co-monomer and has a melting index of 1 g/10 min (230 deg.C, 2,160 g).
Abstract:
