Problems solved by technology

[0004] However, due to the poor compressive strength and wear resistance of the wood-plastic floor during use, it will lead to a decrease in the mechanical properties of the wood-plastic floor surface and shorten the life. Therefore, it is imminent to improve the compressive strength and wear resistance of the wood-plastic composite floor.

Abstract

The invention discloses a method for preparing a mixed plastic-wood flooring material, and the method comprises the following steps: sending polyethylene particles, a lubricant, an antioxidant, an anti UV absorber, a light stabilizer, a heat stabilizer and a preservative into a mixer for stirring to obtain an A material; adding expanded graphite into sodium chloride, adjusting temperature, grinding, adding water, heating, stirring, filtering, washing, drying, adding concentrated sulfuric acid, stirring at room temperature, heating, stirring, alkalifying, adding amino-terminated branched polyethylene glycol, ultrasonically dispersing, filtering, drying, adding the A material, phenolic epoxy resin, glass fiber, silicon carbide fiber and nano silica for evenly mixing to obtain a B material; and adding wood flour and diaminodiphenylmethane for evenly mixing, sending into a granulator for granulation, drying, sending to an extruder for extrusion molding, cooling under vacuum and sanding to obtain the mixed plastic-wood flooring material.

Description

technical field [0001] The invention relates to the technical field of plastic-wood flooring, in particular to a preparation method of a mixed plastic-wood flooring material. 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 wood-plastic flooring. [0004] However, due to the poor compressive strength and wear resistance of wood...
