Abstract
The invention relates to a high-temperature-resistant wood-plastic composite material used for outdoors. The high-temperature-resistant wood-plastic composite material used for outdoors mainly comprises the following components in parts by weight: 40-50 parts of chlorinated polyethylene, 80-90 parts of plant fibers, 3-4 parts of an anti-ultraviolet absorber, 5-6 parts of maleic anhydride grafted polyethylene, 6-8 parts of rare earth chloride, 12-15 parts of a rare-earth stabilizer, 3-5 parts of linoleic acid, 7-8 parts of oxidized polyethlene wax, 6-9 parts of a modifying agent, 10-15 parts of an inorganic filler and 1-2 parts of an antioxidant. A preparation method for the high-temperature-resistant wood-plastic composite material used for outdoors comprises the following steps of: modifying chlorinated polyethylene with rare earth chloride to obtain rare-earth modified polyethylene; pre-treating the plant fibers with the modifying agent; adding all materials into a high-speed mixer to mix, and feeding the mixed materials into a double-screw extruder to extrude and pelletize; and finally, carrying out hot-pressing forming. The high-temperature-resistant wood-plastic composite material effectively improves mechanical strength and high temperature resistance of the wood-plastic composite material, further has ultraviolet resistance, effectively solves the problems that current wood-plastic material is liable to easy and liable to age at a high temperature, is short in service life and the like, and is suitable for outdoor use. The high-temperature-resistant wood-plastic composite material used for outdoors is further beneficial for saving energy sources and increasing a utilization rate of waste plant fibers, is economical and environmentally-friendly.
Description
technical field [0001] The invention relates to the field of chemical materials, in particular to a high-temperature-resistant wood-plastic composite material for outdoor use and its preparation. Background technique [0002] Wood-plastic composite material is a kind of composite material obtained by blending and extruding plant fibers and plastics. Wood-plastic composite material can not only take advantage of the advantages of each component in the material, but overcome the low strength of wood, large variability and the elasticity of organic materials. Due to the limitations of use caused by low modulus, it can make full use of waste wood and plastics, solve the problem of environmental pollution caused by waste plastics that cannot be recycled, and make full use of fiber waste resources. Wood-plastic composite materials have the advantages of high density ratio and low price. And increasing the added value of materials has attracted more and more attention from people,...
