Abstract

The invention discloses an environment-friendly plastic-wood composite tray and a preparation method thereof and belongs to the field of plastic-wood composites. The tray is prepared from raw materials in parts by weight as follows: 15-35 parts of modified bamboo sawdust, 5-8 parts of carbon fibers, 85-95 parts of waste polyethylene particles, 0.6-1 part of benzoin butyl ether, 3-4 parts of N,N-methylene bisacrylamide, 2-5 parts of silicone oil, 0.5-2 parts of polyethylene wax, 0.5-1.5 parts of calcium stearate, 4-6 parts of nano diatomaceous earth, 1-2 parts of zinc oxide, 1-2 parts of epoxidized soybean oil, 1-2 parts of color masterbatch and 0.2-0.8 parts of glycerin. The bamboo sawdust and the waste polyethylene particles are modified in sequence, other aids are added, and the plastic-wood composite tray which is low in cost, light in mass, smooth and bright in surface and colorful is prepared rapidly; the energy-saving and environment-friendly effects are realized while resources are saved.

Description

technical field [0001] The invention belongs to the field of plastic-wood composite materials, in particular to an environment-friendly plastic-wood composite tray and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a new composite material with high performance and high added value, which is made of wood fiber as raw material and plastic through compatibilization and blending process. At present, the plastic matrix in the wood-plastic processing industry generally uses high-density polyethylene, polypropylene, polystyrene, polyvinyl chloride, etc. with relatively low melting points. Natural plant fibers with high aspect ratio, such as wood flour, bagasse, rice husk powder, cotton straw, flax. [0003] The promotion and application of wood-plastic composite materials can also solve the problem of environmental pollution caused by waste plastics that cannot be recycled, and make full use of fiber waste resources, which has certa...
