Abstract

The invention discloses a plastic-wooden composite tray which is prepared from the raw materials in parts by weight: 50-60 parts of high density polyethylene, 20-30 parts of copolymerization polypropylene, 30-40 parts of modified wood meal, 40-50 parts of plastic renewable material, 20-30 parts of active calcium, 1-2 parts of zinc stearate, 1-2 parts of calcium stearate, 2-3 parts of n-butyl methacrylate, 0.3-0.5 part of polyethylene wax, 0.4-0.6 part of triethoxyvinylsilane, 0.3-0.4 part of antioxidant 1010, 0.4-0.6 part of anti-aging agent MB, 8-10 parts of foaming modifier, 4-8 parts of ACM, 4-8 parts of MBS, 25-30 parts of oxidized polyethlene wax, 0.2-0.3 part of foaming agent, 4-8 parts of TPE (Thermoplastic Polyurethane Elastomer), 8-12 parts of chlorinated polyvinyl chloride, 5-8 parts of glass fiber and 3-4 parts of semi-reinforced carbon black. The plastic-wooden composite tray produced by using the preparation method has the advantages of excellent mechanical property, capability of being sawed, planed and nailed, good durability, high repeated usage rate, capability of being recycled, resistance to insect biting, acid and alkaline resistance, aging resistance, and low water absorption and low deformation rate.

Description

technical field [0001] The invention relates to a wood-plastic composite tray and a preparation method thereof, belonging to the technical field of plastic product production. Background technique [0002] At present, the pallets on the market are mainly wooden pallets and plastic pallets. Wooden pallets have a large demand for wood, which is not conducive to the protection of forest resources. In addition, fumigation or high-temperature disinfection treatment is required; and the common problem of plastic pallets is the quality of pallets. The rigidity is not enough, and it is prone to creep phenomenon when it is applied to shelf storage. Wood-plastic pallets are made of wood powder or plant fibers filled with high-value thermoplastic resin or thermoplastic plastic recycled materials, adding some related modifiers, and then extruded and injection-molded. These products can replace the corresponding wooden pallets and plastic pallets , which can save a lot of forest resourc...
