Abstract

The invention relates to a wood-plastic material and a production method thereof. The wood-plastic material comprises the following components in parts by weight: 28-32 parts of thermoplastic, 33-37 parts of wood meal, 33-37 parts of bran powder, 0.2-0.4 part of antioxidant, 0.1-0.2 part of anti-ultraviolet agent, 0.5-1.5 parts of polyethylene wax, 0.25-0.75 part of coupling agent and 1.5-3.5 parts of stearic acid. The thermoplastic powder is mixed with the wood meal and bran powder, and the formula and processing technique are adjusted, thereby preparing the wood-plastic material with stable quality and beautiful appearance; the plastic powder, wood meal and bran powder can adopt tailings or waste, thereby saving the energy and reducing the environmental pollution; and the wood-plastic material has the advantages of favorable dimensional stability and high aging resistance, and can resist the high temperature of 200 DEG C, and the shock strength is 80 kJ / m<2>.

Description

technical field [0001] The invention relates to a novel material, in particular to a wood-plastic material compounded with wood powder and thermoplastic powder and a production method thereof. Background technique [0002] Cement products are often used as building materials for outdoor use. This material is heavy and needs to be constructed in situ. It requires high proficiency of the construction personnel. If the processing is not good, it will be difficult to repair later, and for some high-end products such as tourist attractions. The use of cement materials for gazebos or plank roads is very unsightly. [0003] Wooden materials are very beautiful due to the natural growth of wood grain, but when used outdoors, because the wood has a loose internal structure, it will absorb water and moisture. If it is in a humid environment for a long time, it will rot and require frequent maintenance. . Contents of the invention [0004] In order to solve the problem that cement m...
