POLYPROPYLENE RESIN COMPOSITE WITH IMPROVED MECHANICAL AND FIRE RETARDANT PROPERTIES AND THE CABLE USING THEREOF

摘要

The present invention is 50 parts by weight to 98 parts by weight of a base resin consisting of a polypropylene resin and a polyethylene resin; 2 to 50 parts by weight of maleic anhydride graft polypropylene resin; 1 to 25 parts by weight of organic clay; And 50 parts by weight to 200 parts by weight of the metal hydroxide flame retardant. The present invention is to disperse organic clay nanoscaled on a resin mixed with at least one polyethylene-based resin in a polypropylene resin on a nano-scale, adding a metal hydroxide has excellent mechanical properties, in particular excellent elongation, and at the same time the flame retardancy is remarkable The present invention provides an improved polypropylene resin composition and an electric wire made using the same. The present invention provides the effect of reducing the amount of conventional inorganic flame retardant to provide excellent mechanical properties of the final product, and also has the effect of the invention to enable the production of environmentally friendly products that do not use a halogen-based flame retardant.;Polypropylene, Nanocomposite Resin, Metal Hydroxide, Flame Retardant, Maleic Anhydride, Graft, Organic Clay, Silicate, Alkyl Ammonium, Intercalation, Delamination, Nanocomposite
