Abstract

The invention discloses a high-strength corrosion-resistant wood-plastic composite material for plates and a preparation method thereof. The high-strength corrosion-resistant wood-plastic composite material for plates is prepared from the following raw materials in parts by weight: 100-120 parts of wood meal, 20-30 parts of chlorinated polyethylene, 8-10 parts of polybutadiene rubber, 2-4 parts of bis(2-(2-butoxyethoxy)ethyl)adipate, 3-5 parts of magnesium powder, 5-10 parts of antimony trisulfide, 10-15 parts of nano boehmite, 3-5 parts of bis(P,P-bis-ethylhexyl diphosphato)ethanediolato titanate, 5-8 parts of methylacryloyloxy silane, 14-18 parts of hollow microbead, 6-7 parts of high-boron calcium borate, 3-4 parts of 4-hydroxymethyl-2,6-di-tert-butyl phenol, 8-10 parts of calcium laurate, 10-12 parts of dimethyl terephthalate, 5-7 parts of ethylene-octylene copolymer, 6-8 parts of triphenyl phosphite, 40-50 parts of activated calcium carbonate, 4-6 parts of gypsum whisker, 12-14 parts of ammonium polyphosphate, 5-9 parts of sugarcane wax and 7-8 parts of dimethyl silicone oil. The wood-plastic composite material has the advantages of excellent flame retardancy, excellent mechanical properties, excellent corrosion resistance, excellent aging resistance and longer service life.

Description

technical field [0001] The invention relates to a composite material, in particular to a high-strength corrosion-resistant wood-plastic composite material for plates and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride instead of the usual resin adhesive, and more than 50% of wood powder, rice husk, straw, etc. Waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce panels or profiles. At present, anti-corrosion wood, solid wood floor or composite floor is usually used in the market for municipal, garden, villa outdoor floors, guardrails, fences, pavilions, etc. Preservative wood and solid wood floors consume a lot of wood and are expensive. Although wood-pl...
