The invention discloses a toughened plastic tray prepared from the following raw materials in parts by weight: 50-60 parts of high density polyethylene, 20-30 parts of polyvinyl chloride, 20-30 parts of wood flour, 10-15 parts of silicon carbide, 10-20 parts of modified kaolin, 40-50 parts of recycled plastic polymer, 20-30 parts of active calcium, 1-2 parts of zinc stearate, 1-2 parts of calcium stearate, 2-3 parts of glycerol triglyceride, 0.3-0.5 part of polyethylene wax, 0.4-0.6 part of anilmomethyl triethoxy silane, 0.3-0.4 part of antioxidant 1680, 0.4-0.6 part of anti-aging agent ODA, 8-10 parts of foaming regulator, 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 ACR, 8-12 parts of chlorinated polyvinyl chloride, 5-8 parts of high silica glass fiber, 4-6 parts of mineral fiber and 3-4 parts of semi-reinforced carbon black. The toughened plastic tray produced by the invention has good mechanical properties, good durability, high repeated utilization rate, ageing resistance and corrosion resistance, the tray can be sawed, planed and nailed while needing no steaming or high temperature sterilization treatment, the tray can be flushed and has less possibility of absorbing water and deforming, and no mildew is generated, so that the toughened plastic tray is especially suitable for application at plum rain seasons in the south of the lower reaches of the Yangtze river.
