Abstract

The invention discloses a graphene microchip-nano silver cable material and a preparation method and application thereof. The graphene microchip-nano silver cable material is prepared from, by mass, 65-80 parts of LLDPE resin, 15-30 parts of EVA resin, 0.5-1 part of an antioxidant, 1-4 parts of polyethylene wax, 0.2-0.5 part of zinc stearate, 0.5-1 part of an external fluoride lubricant and 3-6 parts of a graphene microchip-nano silver composite material. The graphene microchip-nano silver cable material has high thermal conductivity and an excellent antistatic effect and can be applied to cable sheaths with antistatic performance and high thermal conductivity, the use effect is better, the quality of cable products is guaranteed, and raw material components are simple, easy to obtain andlow in cost. The preparation method has the advantages that the procedures are simple, the operation is easy, and the controllability is high.

Description

technical field [0001] The invention relates to a graphene microchip-nanometer silver wire cable material, a preparation method and application thereof, belonging to the field of cable materials. Background technique [0002] The wire and cable industry has always been the second largest production industry after the automobile industry in China.
