Abstract

The invention relates to a wood plastic wallboard which is characterized by comprising the following components in parts by weight: 100-110 parts of resin, 110-120 parts of wood dust, 1.5-2 parts of an anti-aging agent, 4-8 parts of a compatilizer, 8-11 parts of a coupling agent, 10-15 parts of CaCO3, 8-12 parts of a lubricating agent, 3-5 parts of a plasticizer and 6 parts of a toughening agent. A preparation method comprises the following steps: 1) adding the resin, the wood dust, CaCO3, the coupling agent, the compatilizer, the plasticizer, the anti-aging agent, the toughening agent and the lubricating agent into a stirrer in sequence to stir, adding one component every 3 minutes, continuously stirring with the stirrer in the whole process and continuously stirring for 10-15 minutes after all the components are added, wherein the mixing temperature is 120 DEG C, and the stirring speed is 750 revolutions / minute; 2) placing a stirred material for 6-8 hours under the airtight condition, wherein the placing temperature is 8-10 DEG C; 3) taking out and putting the material in the step 2) into shaping equipment for extrusion and forming to obtain the wood plastic wallboard. The composite material prepared by the preparation method is low in water absorption rate and excellent in mechanical property and can be widely applied to wallboards, floors and other construction materials.

Description

technical field [0001] The invention relates to the technical field of wood-plastic wallboard processing and production, and to the field of wood product production technology, in particular to a wood-plastic composite wallboard and a different method thereof. Background technique [0002] Wood plastic composite (wood plastic composite, referred to as "WPC") is a new type of composite material that has been booming at home and abroad in recent years. The composite material uses polymer materials such as polyethylene, polypropylene and polyvinyl chloride instead of the usual resin. Adhesives are mixed with more than 35%-70% of wood flour, rice husk, straw and other waste plant fibers to form new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce plates or profiles. Wood-plastic composite materials have many excellent properties, and they are mainly used in building materials, furniture, decoration and...
