NOVELTY - Preparing environmentally-friendly wear-resistant materials from waste polyethylene material comprises e.g. (i) crushing the polyethylene waste using a crusher, screening and collecting by a sorter; (ii) pouring 80-100 pts. wt. polyethylene waste powder, 10-16 pts. wt. chlorinated polyether resin, 10-15 pts. wt. polyethylene terephthalate, 12-21 pts. wt. chlorinated polyethylene, 3-6 pts. wt. alkyl betaine, 1-2 pts. wt. dicumyl peroxide, 2-6 pts. wt. plasticizer glycerol and 1-2 pts. wt. toluene diisocyanate into the mixer and mixing thoroughly to obtain the premix; (iii) adding the premix into the granulator, extruding into molten block materials, cooling by wind, and crushing into soft and dry pellets by crusher; and (iv) adding pellets, wood flour, epoxy resin, fully vulcanized powder acrylic rubber, graphene oxide, potassium dicyclopentadiene dicarboxylate, magnesium hydroxide, alumina powder, coal tar, acicular wollastonite, reinforcing fiber into the mixer and mixing. USE - The method is useful for preparing environmentally-friendly wear-resistant materials from waste polyethylene material. ADVANTAGE - The method: is economical and more environmentally-friendly; produces wear-resistant materials resistant to ozone, oxygen, light and weathering and has high insulation performance and good chemical and water resistance. DETAILED DESCRIPTION - Preparing environmentally-friendly wear-resistant materials from waste polyethylene material comprises (i) crushing the polyethylene waste using a crusher, screening and collecting by a sorter; (ii) pouring 80-100 pts. wt. polyethylene waste powder, 10-16 pts. wt. chlorinated polyether resin, 10-15 pts. wt. polyethylene terephthalate, 12-21 pts. wt. chlorinated polyethylene, 3-6 pts. wt. alkyl betaine, 1-2 pts. wt. dicumyl peroxide, 2-6 pts. wt. plasticizer glycerol and 1-2 pts. wt. toluene diisocyanate into the mixer and mixing thoroughly to obtain the premix; (iii) adding the premix into the granulator, extruding into molten block materials, cooling by wind, and crushing into soft and dry pellets by crusher; and (iv) adding 200-300 pts. wt. pellets, 60-80 pts. wt. wood flour, 20-25 pts. wt. epoxy resin, 20-22 pts. wt. fully vulcanized powder acrylic rubber, 10-18 pts. wt. graphene oxide, 4-8 pts. wt. potassium dicyclopentadiene dicarboxylate, 2-3 pts. wt. magnesium hydroxide, 4-8 pts. wt. alumina powder, 5-9 pts. wt. coal tar, 1-10 pts. wt. acicular wollastonite, 10-20 pts. wt. reinforcing fiber, 1-2 pts. wt. rosin pentaerythritol ester, 4-7 pts. wt. trimethylolpropane triacrylate, 5-8 pts. wt. dibutyltin dilaurate acetyl citrate, 10-16 pts. wt. epoxy soybean oil and 3-6 pts. wt. plasticizer into the mixer, mixing well, adding into the pelletizer to extrude and pelletize to obtain the plastic-wood pellets, adding the plastic-wood pellets into the twin-screw extruder, extruding through a die, cooling the extruded profile in a cooling chamber, and cutting according to the required size.
