Abstract

The invention discloses an easily processed efficient antistatic polypropylene composite material and a preparation method thereof. The polypropylene composite material is prepared from, in weigh percentage, 58-93% of polypropylene, 0-20% of inorganic fillers, 0-10% of toughening agents, 5-10% of antistatic master batches, 0.1-1% of antioxidants and 0.1-2% of other additives. The antistatic master batches comprise, in weigh percentage, 77-89% of carrier resin, 10-20% of antistatic agents and 1-3% of lubricants. The prepared polypropylene composite material has an efficient antistatic performance, surface resistivity can reach 10<9> ohms, original mechanical properties of the material can be kept, and the preparation method is simple, practical and easy in production and avoids the problems of screw slip, smoking and the like.

Description

technical field [0001] The invention relates to an easy-to-process high-efficiency antistatic polypropylene composite material and a preparation method thereof. More specifically, the antistatic performance of the polypropylene material is improved by adding an antistatic masterbatch, which belongs to the technical field of polymer material modification and processing. Background technique [0002] Polypropylene is one of the five general-purpose plastics. Because of its light weight and low price, good physical and chemical properties and processing properties, polypropylene has become the fastest-growing variety of general-purpose resins and is widely used in automotive interior and exterior trims, electronic appliances and other In daily necessities. However, polypropylene material is an electrical insulating material, and the surface resistivity of the material is 10 15 ~10 18 Between Ω, in industrial production and product applications, friction, peeling or induction ...
