Abstract

The invention relates to graphene antistatic plastic, which comprises the following components in percentage by mass: 60-90% of resin, 1-20% of graphene, 5-20% of fire retardant, 1-10% of a dispersing agent, 0.5-5% of an antioxidant, 0.1-5% of a coupling agent and 1-10% of an assistant, wherein the graphene is evenly dispersed into the graphene antistatic plastic; and the assistant is a mixture prepared from magnesium oxide, aluminum oxide and silicon carbide. The invention further provides a preparation method of the graphene antistatic plastic. Through addition of magnesium oxide, aluminum oxide and silicon carbide, the graphene can be evenly distributed, so that the conductivity of the graphene antistatic plastic is improved.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to a graphene antistatic plastic and a preparation method thereof. Background technique [0002] As an important polymer compound material, plastic has a wide range of applications. Unlike metal materials, which are difficult to process, high cost, and low production efficiency, plastics have the advantages of high design freedom, easy processing, and low cost. Therefore, the application of plastics instead of metals continues to expand internationally. However, plastics also have shortcomings. Compared with the high antistatic properties of metals, their antistatic properties are generally poor, which limits the application of plastics in the field of antistatic heat dissipation. [0003] For example, the Chinese patent publication number is CN104292826A, the date of publication is January 21, 2015, and the name is an antistatic plastic and its preparation method. The pa...
