Abstract

The invention discloses a wood-plastic composite. The wood-plastic composite comprises the following components in parts by weight: 30-70 parts of wood meal, 30-100 parts of quaternary recycling plastic, 2-10 parts of a compatilizer, 1-5 parts of a coupling agent, 1-5 parts of an inorganic filler, 1-5 parts of a lubricant, 0.1-2 parts of an anti-oxidant, 0-8 parts of an impact modifier, 0-5 parts of a coloring agent, 0-2 parts of an ultraviolet light absorber and 0-20 parts of a flame retardant. The invention further discloses a preparation method for the wood-plastic composite. According to the wood-plastic composite and the preparation method thereof, the cyclic utilization of the quaternary recycling plastic is realized, the cost of a wood-plastic product is reduced, the quaternary recycling plastic is fully utilized, the application range of a plastic base of the wood-plastic composite is expanded, a new profit growth point is provided for a mechanized garbage sorting treatment process, the present situation that the garbage sorting is non-profit is changed, the development of the mechanized garbage sorting technology is promoted, the sustainable-development technical support is provided for the realization of the city waste reduction, harmlessness and recycling, and the difficult problems in eliminating white pollution are solved.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic materials, and in particular relates to a wood-plastic composite material and a preparation method thereof. Background technique [0002] Wood-plastic, Wood-Plastic Composites (WPC), is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of thermoplastic general-purpose plastics such as polyethylene, polypropylene and polyvinyl chloride, and more than 35% -More than 70% of wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce plates or profiles. Mainly used in building materials, furniture, landscaping, logistics packaging and other industries. [0003] The main WPC varieties are PVC foam WPC, PP WPC, PE WPC and so on. The particle size of the wood powder used can be divided into 40-6...
