Abstract

The invention discloses an anticorrosive wood-plastic composite material and a production process thereof, and belongs to the technical field of wood-plastic composite materials. The anticorrosive wood-plastic composite material comprises the following components: 30-45 parts of wood powder, 20-35 parts of wheat straw powder, 15-25 parts of epoxy resin, 5-15 parts of cashew nut shell oil modifiedphenolic amine resin, 5-10 parts of graphite, 10-20 parts of shell powder, 5-10 parts of quartz micro powder, 10-15 parts of sanding powder, 2-8 parts of an epoxy reactive diluent, 6-12 parts of an auxiliary agent, 3-9 parts of a coupling agent, 4-8 parts of a stabilizer, 6-10 parts of a plasticizer and 8-15 parts of a filler, wherein the epoxy resin is organic silicon modified epoxy resin, the graphite is expandable graphite, and the stablizer is composite rare earth. According to the invention, through use of epoxy resin, expandable graphite, quartz micro powder and shell powder, corrosion resistance of the material is improved; and meanwhile, through use of composite rare earth and nano glass fibers, fireproof flame-retardant performance and mechanical strength performance of the wood-plastic composite material are further improved.

Description

technical field [0001] The invention relates to a wood-plastic composite material and a production process thereof, in particular to an antiseptic wood-plastic composite material and a production process thereof, belonging to the technical field of wood-plastic composite materials. 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. Mainly used in building materials, furniture, logistics packaging and other industries. The board formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called ex...
