Abstract

The invention discloses a method for preparing a lipid-plastic composite material by adopting surface-activated epoxy resin powder. The lipid-plastic composite material comprises the following components in parts by weight: 23-25 parts of wood flour, 19-23 parts of PE (polyethylene) particles, 24-26 parts of epoxy resin powder, 20-25 parts of a polymethacrylate reclaimed material, 5-6 parts of a polystyrene-butadiene copolymer reclaimed material, 1-2 parts of a lubricant, 0.2-0.5 part of an antioxidant, 1-2 parts of maleic anhydride grafted polyethylene, 0.5-1 part of a silane coupling agent,0.5-1 part of a stabilizer, 0.3-0.5 part of a modifier and 1-2 parts of a dye. According to the invention, the mechanical strength and the service life of the lipid-plastic composite material are greatly improved; meanwhile, the polymethacrylate reclaimed material and the polystyrene-butadiene copolymer are used as a modified material, the toughness of the lipid-plastic composite material is improved, and the bending damage load and the ball falling impact strength of the material are improved. The lipid-plastic composite material can be applied to outdoor product markets such as landscape landscapes, building exterior wall decoration and the like.

Description

technical field [0001] The invention relates to a preparation method of a fat-plastic composite material, in particular to a method for preparing a PE fat-plastic composite material by adopting surface chemically activated epoxy resin powder. Background technique [0002] With the rapid economic and social development in recent years, bulk electrical and electronic products represented by TVs, refrigerators, washing machines, air conditioners, computers, mobile phones, etc. have entered a new era of "mass production, mass consumption, and mass waste", resulting in A lot of electrical and electronic waste.
