Abstract

The invention relates to a metallocene polyolefin tenacity-increased profax resin composition comprising raw materials of the following constituents (by weight proportion): polypropylene 60-85%, metallocene polyolefine 5-30%, compatibilzer 5-10%, anti-oxidant 0.1-1% and lubricating agent 0.1-0.5%.

Description

technical field [0001] The invention relates to a metallocene polyolefin toughened polypropylene resin composition, which can be used to manufacture auto parts and electrical and electronic components, and belongs to the technical field of polypropylene modification. Background technique [0002] Polypropylene (PP) is cheap, light, corrosion-resistant, has good processability, good mechanical balance, wide application range, and has the best heat resistance among general-purpose resins. Polypropylene is widely used in the automotive industry, and its engineering tendency is very obvious. However, the toughness of polypropylene, especially the low-temperature impact toughness, is very poor, which limits its use. [0003] There are many ways to improve the toughness of polypropylene. The most researched is ethylene-propylene rubber toughened polypropylene, and HDPE and ethylene-propylene rubber synergistically toughened polypropylene. The dynamic vulcanization technology devel...
