Electromagnetic shielding polyethylene material and preparation process thereof

Abstract

The invention relates to an organic polymer composite material, in particular to a polyethylene material capable of electromagnetic shielding and a preparation method thereof. The polyethylene material comprises the following components in percentage by weight: 49.5-90 percent of polyethylene, 5-35 percent of carbon fiber, 2-30 percent of conductive graphite, 0.2-1.0 percent of antioxidant, 0.2-2.0 percent of coupling agent and 0.3-5.5 percent of other auxiliary agent. The electromagnetic shielding polyethylene material can replace metal raw materials to produce spare and accessory parts or casings, and combines the favorable performance of thermoplastic plastics which can be processed easily and the electromagnetic shielding function of metal materials, therefore, the production purchasing of the electromagnetic shielding polyethylene material can be realized conveniently, and the relevant cost can be greatly reduced. The electromagnetic shielding polyethylene material also has the advantages of acid-resistant and alkali-resistant corrosion, certain mechanical strength and temperature toleration, thereby comprehensively improving the competitiveness.

Description

technical field [0001] The invention relates to an organic polymer composite material, in particular to an electromagnetic shielding polyethylene material and a preparation method thereof. Background technique [0002] At present, the use of plastics to replace metals continues to expand internationally. Scientists from all over the world are actively looking for new functional thermoplastics through various experiments, which has become an important part of companies' efforts to win more customers and expand market share. [0003] However, the conductivity and electromagnetic shielding properties of metals are not available in ordinary plastics. At present, in many fields such as civil electronic appliances / toys / communications / cables / military industry, parts that need electromagnetic shielding functions are involved. At present, the market of this series of products basically has to use metal raw materials for production, and suffers from a series of shortcomings such as d...
