Problems solved by technology

The waste plastics recycled in my country are mainly a mixture of polyethylene, polypropylene and polystyrene. Due to the poor compatibility between various plastic components and the low polarity of the blend, the interface compatibility with wood fiber materials is poor. , the mechanical properties of the prepared wood-plastic composites are poor, especially the low impact resistance, which is not suitable for the production of wood-plastic composite products with high performance requirements

Abstract

The invention discloses a processing method of a high-strength impact resistance type wood-plastic composite plate and relates to the technical field of wood-plastic composite plates. The processing method comprises the following steps of (1) mixture processing; (2) wood-plastic composite plate pellet processing; and (3) wood-plastic composite plate processing. According to the processing method provided by the invention, by taking ABS (acrylonitrile-butadiene-styrene copolymer) as a main material, coconut coir as a cellulose auxiliary material and light calcium carbonate as a filler and by adding functional additives (a flame retardant, an antioxidant and an ultraviolet light absorber), the wood-plastic composite plate is prepared; the prepared wood-plastic composite plate has excellent mechanical performance, flame retardancy and weathering resistance, and the service life of a wood-plastic floor is remarkably prolonged; and meanwhile, recycle of the coconut coir is realized, and theproblem of limited resources by taking wood flour as the cellulose auxiliary material is solved.

Description

Technical field: [0001] The invention relates to the technical field of wood-plastic composite boards, in particular to a processing method for high-strength impact-resistant wood-plastic composite boards. Background technique: [0002] Wood-plastic composite board is a kind of wood (wood cellulose, plant cellulose) as the basic material, thermoplastic polymer material (plastic) and processing aids, etc., which are mixed evenly and then heated and extruded by mold equipment. It is a high-tech green and environmentally friendly new decorative material, which has the properties and characteristics of wood and plastic, and is a new composite material that can replace wood and plastic. Wood-plastic composite panels not only have the characteristics of waterproof, moisture-proof, insect-proof, termite-proof, high fire resistance, no cracking, no expansion, no deformation, good sound-absorbing effect, strong plasticity, and are environmentally friendly, which greatly saves the use...
