Abstract
The invention relates to a high-wear-resistance wood-plastic floor board and a preparation method thereof. The preparation method comprises the following steps: adding a polyurethane elastomer and a compatilizer into a high-speed mixer, and carrying out melt blending at the high temperature of 130-150 DEG C for 20-30 minutes to obtain modified polyurethane; adding recycled plastic, plant fiber and the modified polyurethane into the high-speed mixer, and mixing and stirring at 100-130 DEG C for 20-30 minutes to obtain a blend compound I; and mechanically mixing the blend compound I with a lubricant and plastic processing assistants for 15 minutes, melting at high temperature, plastifying and granulating; and melting the granules with a special wood-plastic extruder, setting, cooling, cutting, and carrying out after-treatment according to the demands of customers to obtain the high-wear-resistance wood-plastic floor board. The preparation method has the advantages of simple production technique, low cost, no need of after-treatment, no use of any organic solvent, and no emission of toxic or harmful gas. On the premise of enhancing the wear resistance, the method does not lower the strength of the material, obviously enhances the wear resistance of the material, greatly lowers the water absorptivity, prolongs the service life and widens the application range.
Description
technical field [0001] The invention belongs to the technical field of wood-plastic composite materials, and in particular relates to a high wear-resistant wood-plastic floor and a preparation method thereof. Background technique [0002] Wood-plastic composites are made from agricultural and forestry waste and waste plastics through the principle of polymer interface compatibility, and are a new type of wood-replacing product. This product is of great significance for the comprehensive utilization of resources, environmental protection, and conservation of forest resources. [0003] Wood-plastic composites have the dual characteristics of wood and resin, with excellent mechanical properties, high strength, good dimensional stability, and excellent processability, which can be nailed, planed, and sawed. The material can also be recycled repeatedly, and it is a real "green" new material. Widely used in garden landscape construction, industrial and civil construction, decora...
