Durable composite material tray and production method thereof

Abstract

The invention discloses a durable composite material tray. The material is prepared from the following raw materials in parts by weight: 50-60 parts of high-density polyethylene, 40-50 parts of co-polymerized polypropylene, 30-40 parts of mixed fiber, 20-30 parts of plastic reclaimed material, 5-9 parts of artificial zeolite, 1-2 parts of zinc stearate, 1-2 parts of calcium stearate, 6-13 parts ofpolyethylene glycol distearate, 12-15 parts of unsaturated polyester resin, 0.4-0.6 part of vinyltriethoxysilane, 0.3-0.4 part of antioxidant, 0.4-0.6 part of an anti-aging agent, 8-10 parts of a foaming regulator, 4-8 parts of a coupling agent, 25-30 parts of oxidized polyethylene wax, 0.2-0.3 part of a lubricant, 8-12 parts of chlorinated polyvinyl chloride and 3-4 parts of semi-reinforced carbon black. By adding the raw materials such as the high-density polyethylene, the co-polymerized polypropylene, the mixed fibers and the plastic reclaimed material, fusion is more sufficient, the mechanical property is excellent, meanwhile, the plant straw is recycled, resources are saved, and the building construction cost can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic pallets, and more specifically relates to a durable composite material pallet and a production method thereof. Background technique [0002] Wood-plastic, that is, wood-plastic composite material, refers to the use of polyethylene, polypropylene and polyvinyl chloride, etc., instead of the usual resin adhesive, mixed with more than 35%-70% of waste plant fibers such as wood powder, rice husk, straw, etc. It is made of new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce excellent profiles. Due to the unreasonable setting of the raw materials of the existing wood-plastic pallets, the physical and chemical properties of the joints between the raw materials are poor, and the mechanical properties such as structural strength and toughness after molding are not good, and they are not durable. Therefore, we propose a dura...
