Problems solved by technology

The packaging box of electronic components is also a large number of application fields of polyethylene. Due to the high insulation of polyethylene material itself, if it is used as the packaging field of electronic components, there will be electrostatic adsorption on the surface, which will easily cause dangers such as electric shock and fire.
Some polyethylene packaging boxes in the transportation industry can also cause fires due to static electricity on the surface, causing unnecessary losses and dangers

Abstract

The invention relates to the field of preparation of high polymer materials and in particular to a polyethylene composite material jointly modified by graphene, carbon nano tubes and fullerene. The material is prepared from the following components: 50 to 100 parts of polyethylene, 0.1 to 1 part of the graphene, 0.1 to 1 part of the carbon nano tubes, 0.1 to 1 part of the fullerene, 2 to 10 parts of maleic anhydride grafted polyethylene, 1 to 3 parts of antioxidant, 1 to 3 parts of plasticizer and 1 to 2 parts of coupling agent. According to the polyethylene composite material disclosed by the invention, two-dimension graphene, one-dimensional carbon nano tubes and zero-dimensional fullerene are mixed to set up a three-dimensional carbon material antistatic network; a carbon material with smaller proportion is used in a polyethylene matrix to construct a conductive network. The composite material has the advantages that a processing technology is simple, and batch production can be realized; products obtained by one-time injection molding can be applied to the field of antistatic electricity.

Description

technical field [0001] The invention relates to the field of polymer material preparation, in particular to a polyethylene composite material jointly modified by graphene, carbon nanotubes and fullerene and a preparation method thereof. Background technique [0002] The zero-dimensional fullerene discovered in 1989, the one-dimensional carbon nanotube discovered in 1991, and the two-dimensional graphene discovered in 2004 are all popular materials in the carbon material family. "darling". These materials all have good electrical conductivity. As a representative of new materials in the 21st century, graphene has attracted much attention for its excellent electrical and thermal conductivity and mechanical strength. [0003] Polyethylene, which is widely used in industry, is polymerized from ethylene monomer and is divided into high-density polyethylene and low-density polyethylene. It can be used to prepare films, hollow products, pipes, fibers and containers, sealed box m...
