Abstract

The invention discloses a polypropylene whitening resistant auxiliary agent and application thereof. The polypropylene whitening resistant auxiliary agent is prepared from hyperbranched dispersing agents, hyperoxide and talcum powder. Through being metered by mass, the recipe ratio of the hyperbranched dispersing agents to the hyperoxide to the talcum powder is (5 to 8) to (50 to 60) to 100; the particle diameter of the talcum powder is 4000 to 10000 meshes; the effect of reducing the polypropylene whitening is achieved.

Description

technical field [0001] The invention relates to an anti-whitening auxiliary agent for polypropylene and its application. Background technique [0002] Polypropylene (PP for short) is a semi-crystalline thermoplastic with high impact resistance and is widely used in industry. In the actual use process, it is found that there is whitening of polypropylene, which needs to be solved urgently. SUMMARY OF THE INVENTION [0003] The first object of the present invention is to provide an anti-whitening auxiliary agent for polypropylene, which has the effect of reducing the whitening of polypropylene. [0004] The above-mentioned technical purpose of the present invention is achieved through the following technical solutions: [0005] An anti-polypropylene whitening auxiliary agent, comprising a hyperbranched dispersant, peroxide and talc; in terms of mass, the formula ratio of the hyperbranched dispersant, peroxide and talc is 5-8:50~ 60:100; the particle size of the talc powde...
