Abstract
The invention discloses a wear-resistant shock-absorbing wood-plastic sheet material comprising outer sheet materials and a core material. The outer sheet materials are arranged on the two sides of the core material. Connection parts are arranged on the two ends of the outer sheet materials. Buffering shock-absorbing layers are arranged between the outer sheet materials and the core material. A plurality of through holes extending along the length direction of the core material are provided in the buffering shock-absorbing layers. The outer sheet materials are formed by compactly arranging a plurality of trapezoids along a horizontal direction. Grooves extending along the length direction of the through holes are formed among the trapezoids. The main material for the buffering shock-absorbing layers is foamed modified starch. According to the invention, the wear-resistant shock-absorbing wood-plastic sheet material is a composition of 3 layers of materials with different properties. The sheet material has high wear resistance and good buffering and shock-absorbing performances. With the sheet material, crack propagation can be effectively prevented. The sheet material has high compactness, good water resistance, high flame retarding performance, good wood texture, no toxicity, and no harm. The material is environment-friendly and energy-saving.
