Flame-retardant wood-plastic compound material tray

Abstract

The invention relates to the technical field of plastic product production, and particularly discloses a flame-retardant wood-plastic compound material tray. The tray is prepared from the following raw materials in parts by weight: 50-70 parts of bamboo powder, 45-60 parts of high-density polyethylene, 1-4 parts of silane coupler KH550, 0.3-2 parts of maleic anhydride grafted polyethylene, 0.5-2 parts of sodium stearate, 1-2 parts of polyethylene wax, 0.5-1 part of azodiisobutyronitrile, 3-7 parts of muscovite, 0.2-1 part of p-phenylenediamine, 0.2-1 part of antioxidant 1076, 1-2 parts of black masterbatch, 9-13 parts of compound flame retardant and 6-10 parts of modified carbon black. The flame-retardant wood-plastic compound material tray has excellent electrostatic resistance and flameretardance.

Description

technical field [0001] The invention relates to the technical field of plastic product processing, in particular to a flame-retardant wood-plastic composite tray. 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 composite pallets are made of wood powder or plant fibers filled with high-value thermoplastic resin or thermoplastic plastic recycled materials, and some related modifiers are added, and then extruded and injection-molded. These products can replace the corresponding wooden pallets and Plastic pallets can save a lot of forest resources, ...

Problems solved by technology

However, because thermoplastics, one of the main raw materials of wood-plastic composite materials used in wood-plastic composite pallets, are good electrical insulators, they are still poor conductors of electricity after being combined with wood fiber materials, and they tend to accumulate a large amount of electricity during use. Electrostatic charge, causing dust suction, discharge, breakdown and other dangers, and even burning or explosion, there is a huge potential safety hazard

In addition, wood-plastic composite materials are flammable materials, which largely limits the application of wood-plastic composite pallets
