Abstract

The invention relates to the technical field of high polymer materials, and particularly provides a flame-retardant antistatic polyethylene composite material as well as a preparation method and application thereof. The material comprises the following components in parts by mass: 20-60 parts of polyethylene resin, 5-30 parts of glass fiber, 0.5-3 part of a lubricant, 1-10 parts of a compatilizer,0-5 parts of a flexibilizer, 0.2-0.5 part of an antioxidant, 15-40 parts of antistatic master batch and 5-10 parts of flame-retardant master batch, wherein the glass fibers are alkali-free glass fiber twistless rough yarns, and the fiber diameter is 8-15 microns. The problems in the prior art that an antistatic polyethylene material is short in service life and low in safety coefficient, the flame-retardant performance is affected after the flame-retardant polyethylene material is doped with glass fibers for reinforcement, and the reinforcement effect is poor are solved.

Description

technical field [0001] The disclosure relates to the technical field of polymer materials, and specifically provides a flame-retardant and antistatic polyethylene composite material as well as a preparation method and application thereof. Background technique [0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Polyethylene (PE for short) has excellent low temperature resistance (the lowest operating temperature can reach -100 ~ -70 ° C), good chemical stability, and can withstand most acid and alkali erosion. Now polyethylene is widely used in film products, tube sheets, hollow products, injection molding products and other fields. However, due to the limited strength of polyethylene itself, high-density polyethylene with a higher yield strength can only reach 23MPa, even as an engineering plastic. The strength of processed ultra-high molecular weight polyethylene is on...
