Problems solved by technology

The above three methods all have the advantages of convenient processing and no need to make major changes to the process formula, but there are also inherent disadvantages
[0005] 1. Add antistatic agent: antistatic agent is composed of some low-molecular organic compounds. After being added to polyethylene molding, it will precipitate on the surface of the product to form antistatic polyethylene to achieve antistatic effect. Therefore, the antistatic effect on the surface and inside of the product The electrostatic effect is not the same. Secondly, the antistatic agent is volatile, which affects the service life of the product. Since the antistatic agent is a small molecular organic compound, adding too much will cause "blooming" phenomenon and affect the use
[0006] 2. Add conductive carbon black: Conductive carbon black is a kind of carbon black with ext

Abstract

The invention discloses a regenerated polyethylene-graphene composite conducting material and a preparation method thereof. The conducting material comprises the following components in parts by weight: 100 parts of regenerated polyethylene, 3-10 parts of a flexibilizer, 0.1-10 parts of graphene microchips, 2-15 parts of a dispersing agent, 1-10 parts of a compatilizer, 0.3-1 part of an antioxidant and 0.1-25 parts of a filling agent. The preparation method comprises the steps of firstly preparing master batches from regenerated polyethylene and the graphene microchips, uniformly mixing the master batches with polyethylene and residual aids, feeding the mixture into a double-screw extruder, and carrying out extruding granulation. The surface resistivity of the conducting material can be decreased to 10<4> or less, and meanwhile, the conducting material preserves good physical and mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a composite conductive material of recycled polyethylene and graphene and a preparation method thereof. Background technique [0002] Polyethylene has good physical and mechanical properties, electrical properties and chemical stability, and good processing performance. It can be used for a long time at 80-110 ° C. It can be made into plates, pipes, films, fibers and containers of different sizes. It is widely used in Industry, agriculture, medicine and health and daily necessities industry. [0003] Due to the excellent electrical insulation properties of polyethylene, the plates, equipment, and films produced with polyethylene have static electricity, which greatly affects the application of polyethylene in the electronics industry. Therefore, people have introduced antistatic polyethylene materials. [0004] The antistatic polyethylene materials in the p...
