Abstract

The invention discloses a wood-plastic composite floor board and a preparation method thereof, which belongs to the field of construction materials. The preparation method comprises the following steps: mixing diatomite and a coupling agent, ball milling to obtain ball abrasive, open mixing the ball abrasive, blended rubber, polyurethane resin, ethylene vinyl acetate, polymethyl methacrylate, sulfur, accelerant, an antiaging agent and plasticizer, standing, parking, obtaining an intermediate layer, uniformly mixing PVC resin, modified polypropylene, modified carbonized rice hulls, zinc stearate, antioxidant, silane coupling agent KH-560 and plasticizer, calendaring into sheets, obtaining a matrix layer, finally adopting the matrix layer as a bottom layer, laying an intermediate layer on the matrix layer, laying a surface layer on the intermediate layer, molding by hot pressing, and cutting, thus obtaining the wood-plastic composite floor board. The wood-plastic composite floor board has the beneficial effects: the wood-plastic composite floor board has relatively high bending strength and elastic modulus, relatively good bending performance and is uneasy to have cracks in the application process.

Description

technical field [0001] The invention relates to a wood-plastic composite floor and a preparation method thereof, belonging to the field of building materials. Background technique [0002] Wood-plastic flooring is a new type of environmentally friendly wood-plastic composite material product. The main materials are polyethylene and wood powder or bamboo powder. After adding additives and mixing at high speed, it is pelletized, and then the pellets are extruded by an extruder. Formed wood, that is, wood-plastic flooring. It can overcome the problems that the wooden floor is easy to absorb water and swell, crack and deform, and the composite wood floor contains formaldehyde to pollute the environment. However, the wood-plastic floor made by extrusion molding is hard to control the distribution and size of the cells, which leads to shrinkage and warping of the wood-plastic floor at high temperature. In addition, the thermal bonding effect of the hard base layer is poor. There...
