Abstract

The invention discloses a fiber reinforced high-density polyethylene / graphite / graphene composite material and a preparation method thereof. The composite material is prepared from the following components in parts by weight: 30-50 parts of natural plant fibers, 10-20 parts of graphite powder, 0.5-2 parts of graphene, 40-60 parts of polyolefin, 6-10 parts of a foaming agent, 0.5-1 part of a crosslinking agent, 5-8 parts of a plasticizer, 1-10 parts of a lubricant and 7-10 parts of an activating agent. The fiber reinforced high-density polyethylene / graphite / graphene material prepared by treatingthe natural plant fibers with the aid of other processing aids has excellent processing performance and physical mechanical properties. The problem of compatibility of natural plants with polyolefinis solved, so that the composite material with high strength and good toughness is obtained; and with the addition of the graphene, the heat-conducting performance of the composite material provided by the invention can be effectively increased, so that the fiber reinforced high-density polyethylene / graphite / graphene composite material has a wide application prospect.

Description

technical field [0001] The present invention relates to a polyethylene material, more specifically, to a fiber-reinforced high-density polyethylene / graphite / graphene composite material and a preparation method thereof. Background technique [0002] High-density polyethylene (HDPE) is a white powder or granular product. It is non-toxic, tasteless, with a crystallinity of 80% to 90%, a softening point of 125 to 135°C, and a service temperature of up to 100°C; hardness, tensile strength and Creep property is better than that of low-density polyethylene; wear resistance, electrical insulation, toughness and cold resistance are better; chemical stability is good, and it is insoluble in any organic solvent at room temperature, and it is resistant to acids, alkalis and various salts. Corrosion; the film has low permeability to water vapor and air, and low water absorption; poor aging resistance, environmental stress cracking resistance is not as good as low-density polyethylene, an...
