Problems solved by technology

[0002] Wood-plastic composite materials are prepared by mixing plastic and wood powder and other fibers, and have the characteristics of plastic and wood fibers at the same time, which not only improves the mechanical properties and processing properties of the material, reduces costs, expands the application range, but also improves the recycling of materials. At the same time, compared with pure plastic materials, wood-plastic composite materials contain lignocellulose. In the case of relatively humid environment, the composite materials are easy to mildew and breed bacteria. The existing wood-plastic materials have relatively hard surface texture and low friction. Smaller and prone to slipping in the presence of water

Abstract

The invention discloses a skin-friendly wood-plastic composite board comprising the following components by mass: 35-50% of wood powder, 25-35% of high density polyethylene, 15-20% of talcum powder, 2-3% of a graft compatibilizer, 1-2% of a composite lubricant, 0.2-0.5% of an antioxidant, and 5-8% of an elastomer material. The end face of the composite board is divided into two layers, a surface layer is an elastomer material, the inner layer is a wood plastic material, and the two layers are firmly fused together. The surface layer has the characteristics of softness, high frictional force and good skin friendliness, people are not easy to slip when walking on the board, and the safety is high; the inner layer provides enough mechanical strength support to ensure long-term stable use of the product.
