Toughened plastic tray and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention relates to a toughened plastic 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; while wooden pallets are subject to various restrictions, Some non-wood material pallets came into being. These non-wooden pallets, such as plywood pallets, paper pallets, plastic pallets and other new material pallets, do not need to be sterilized, but they are not perfect. Inherent material defects or high manufacturing costs make these pallets unable to fully replace wooden pallets . There have been plastic wood materials for this reason. Wood-plastic materials can produce many products, one of which is c...
