Abstract

The invention discloses an environment-friendly type wood and plastic composite material, and relates to the technical field of novel materials. The environment-friendly type wood and plastic composite material is prepared from the following components of modified wood powder, polyethylene resin, polyvinyl alcohol, calcium carbonate, mulberry leaf powder, a lubricant, epoxy soybean oil, and an organosilane coupling agent. The environment-friendly type wood and plastic composite material is obtained after multiple times of design of raw materials and components and massive experiment data, andhas the advantage that the modified wood powder can be bound with polyethylene plastic, so that the strength of wood and plastic material is obviously enhanced.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to an environment-friendly wood-plastic composite material. Background technique [0002] Wood-plastic composite (WPC) is prepared by compounding thermoplastics and wood fibers or plant fibers. This material has the dual characteristics of wood and plastics. High abrasiveness and impact resistance, the product can be recycled. However, due to the different surface properties of the plant fiber and the resin matrix, the interface bonding effect is poor when the two are combined, which leads to the reduction of various properties of the composite material and affects the popularization and application of the composite material. The existing non-polar or low-polar thermoplastic materials are composited with wood raw materials. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly wood-plastic composite materia...
