Polypropylene modified plastic

Abstract

The invention discloses a polypropylene modified plastic which comprises polypropylene and an additive, wherein the additive comprises a weather-proof agent, a filling agent, a flexibilizer and an antioxidant; the weather-proof agent is dilauryl thiodipropionate or zinc oxide; the filling agent is glass fiber, talcum powder or asbestos; the flexibilizer is ethylene propylene diene monomer, SBS or POE (polyolefin elastomer); and the antioxidant is an antioxidant 1010, antioxidant 1076 or phosphite ester antioxidant. By proportionally mixing the materials, the anti-bending fatigue of the polypropylene modified plastic disclosed by the invention is enhanced, and the mechanical performance is remarkably improved; the polypropylene modified plastic has higher impact strength at a low temperature of -40 DEG C, is not easily aged and cracked at a high temperature of 150 DEG C, and is corrosion-resistant and suitable for the automobile industry and other related industries; and moreover, with light weight and strong impact resistance, the polypropylene modified plastic is an ideal steel substitute.

Description

technical field [0001] The invention relates to a plastic formulation, in particular to a polypropylene modified plastic. Background technique [0002] Polypropylene is a thermoplastic with high impact resistance, strong mechanical properties, resistance to various organic solvents and acid and alkali corrosion, the most prominent performance is bending fatigue resistance, and it is widely used in the industry. One of the common polymer materials, such as microwave oven fresh-keeping boxes, in fact, polypropylene has strong competitiveness in the automotive industry, but because of its relatively low heat resistance, easy aging, poor impact strength at low temperatures, low Embrittlement will occur at -35°C, so it cannot be directly used as spare parts for automobiles. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a polypropylene modified plastic, which can have high impact strength at low temperature and is ...
