Abstract

The invention provides a permanent antistatic micro-foaming polypropylene composite material and a preparation method thereof, and relates to the technical field of polymer materials. The composite material is prepared from polypropylene resin, a flexibilizer, filler, antistatic master-batches, a foaming agent, an antioxidant, an optical stabilizing agent and a lubricating agent. The polymer permanent antistatic agent can form a polymer network structure in the polymer, is permanently antistatic, still has an antistatic effect in an extremely low humidity environment, and has the advantages of good thermal stability and good chemical resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a permanent antistatic micro-foamed polypropylene composite material and a preparation method thereof. Background technique [0002] Experimental studies have shown that for every 10% reduction in vehicle quality, fuel consumption decreases by 8%, and emissions decrease by 4%. Vehicle lightweight can take into account the dual goals of improving fuel economy and environmental protection. Lightweight is an inevitable trend in the development of the automobile industry, mainly due to the promotion of the current global trend of energy conservation and emission reduction. Automobile lightweight technology can help automobiles reduce weight and reduce fuel consumption, which is one of the most important measures to achieve energy conservation and environmental protection. Large-scale application of composite materials to achieve weight reduction is the main development stra...
