Masterbatch composition for injection molded polyolefin resin showing natural stone pattern and method for manufacturing polyolefin resin molded article using the masterbatch composition

摘要

The present invention relates to a master batch composition which can be applied to the production of a molded polyolefin resin which causes a natural stone patterned outer plate such as marble, granite and the like, and a process for producing a polyolefin resin molded article using the master batch composition. It is difficult to apply the present invention to a molded product having complicated shapes because the pattern is formed after the injection molding. Therefore, the present invention provides a polyolefin resin composition comprising 30 to 50 parts by weight of a polyolefin resin, 45 parts by weight of a modified polypropylene resin binder, about 10 parts by weight of a modified polypropylene resin binder and an appropriate amount of a pigment, a dispersant, and an auxiliary agent, and about 2 to 3 parts by weight of the masterbatch composition for injection-Manufacture of polyolefin resin molded article by injection molding at 220C Act as a molded exterior to allow a natural stone pattern may direct.
