Abstract

The invention provides a high wear-resistant wood-plastic composite and a preparation method thereof, and relates to a composite obtained by mixing modified plant fiber powder, modified nano ceramics particles and plastic powder. The high wear-resistant wood-plastic composite comprises the modified plant fiber powder, the modified nano ceramics particles, the recycled plastic powder and the like, wherein the modified nano ceramics particles comprises modified nano Al2O3, modified nano Si3N4, modified nano SiC or the mixture thereof, which can obviously improve the microhardness of the wood-plastic composite, reduce the wear rate and improve the mechanical property. The high wear-resistant wood-plastic composite is prepared from the components by the common melt-mixing method in the plastic processing. The surface hardness and the wearability of the wood-plastic composite are greatly increased, and the strength and the toughness are also greatly improved, so that the overall performance of the wood-plastic composite is greatly enhanced. The wood-plastic composite can be used in the fields of construction material, furniture, package and the like.

Description

technical field [0001] The invention relates to a wood-plastic composite material, in particular to a high wear-resistant wood-plastic composite material prepared by using waste plastic powder, modified plant fiber powder and modified nano-ceramic particles and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a new type of environmentally friendly material produced by blending natural fiber powder with a certain length-to-diameter ratio such as wood, straw, and rice bran with thermoplastics, and producing it by hot pressing, extrusion or injection molding. Because wood-plastic composite materials combine the dual advantages of wood fiber materials and polymer materials, wood-plastic composite materials have excellent comprehensive properties. It has good mechanical strength, high impact resistance, lower heat shrinkage than plastics, better water and moisture resistance than wood, stable size, chemical corrosion resistance, insec...
