Abstract

The present invention is wear-resistant wood-plastic floor board and its production process, and belongs to the field of decoration material technology. Polyvinyl chloride resin or plastic material is added with waste wood powder or fiber material powder, active calcium carbonate, assistant, stuffer, etc, and the mixture is pelletized, and further treated through extruding, molding, vacuum cooling, settling, drawing and cutting to form the basic wood-plastic board. The basic wood-plastic board is polished, groove milled and covered with surface decoration layer to form the wear resistant wood-plastic floor board product. The wear resistant wood-plastic floor board is beautiful, wear resistant, fireproof, waterproof, non-skid, anticorrosive and environment friendly and has high strength, heat insulation, electrical insulation and other advantages.

Description

technical field [0001] The invention relates to a wear-resistant wood-plastic floor and its production process, specifically for decoration of homes and offices, and belongs to the technical field of decoration materials. Background technique [0002] The floor that is used for family, office room decoration usually adopts solid wood floor or compound floor on the market at present. Solid wood flooring consumes a lot of wood and is expensive. Although it has the advantages of wear resistance, it has poor water resistance after laying and use, and is easy to crack and warp. Composite flooring is made by mixing and extruding wood chips and adhesives. Although it has the advantages of lightness and cheap price, it has poor water resistance and wear resistance, low mechanical properties, instability, and it will also warp after being soaked in water. The decorative effect is poor and the service life is short, so it is not easy to be accepted by people. Contents of the invent...
