Nano modified wood-plastic composite plate and preparation method thereof

Abstract

The invention relates to wood-plastic composite materials, in particular to a nano modified wood-plastic composite plate and a preparation method thereof. The preparation method includes stirring polyvinyl chloride plastic particles, tribasic lead sulfate, nano kaolin, talcum powder, terpene resin, polyolefin elastomer, butyl stearate and oxidic polyethylene, then extruding and pelleting to obtain modified plastic particles; mechanically stirring and mixing the modified plastic particles, azodicarbonamide and wood powder again, and then melting, mixing, extruding and foaming by an extruder to obtain the nano modified wood-plastic composite plate. The nano modified wood-plastic composite plate is convenient to produce and manufacture, is high in mechanization degree and low in required labor during production and low in production cost, and further, is low in plastic usage, environment-friendly, low in density, excellent in impact resistance, long in service life and convenient to mount and maintain, has a certain function of air purifying, and can be widely applied to places such as high-end buildings, homes and offices.

Description

technical field [0001] The invention relates to a wood-plastic composite board, in particular to a nano-modified wood-plastic composite board 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 uses plastic, wood powder, etc. as the main raw materials, supplemented by other additives, and is a green and environmentally friendly material that is extruded, molded or injected. Compared with pure wood, it does not require anti-corrosion treatment during use, is environmentally friendly, does not require daily maintenance, has a longer service life than wood, does not absorb moisture, does not rot, is insect-proof, and is not sensitive to cold and hot environments. It has good strength performance, excellent adjustable performance, UV light stability, good colorability, wide source of raw materials, can be made into any shape and size acco...

Problems solved by technology

But there are also some obvious deficiencies, such as high density, poor impact resistance, inability to absorb toxic and harmful gases, etc., so its scope of use is mostly limited to outdoor use, but it has not been fully applied in interior decoration.
