At present, the existing plastic-wood composite material preparation technology mainly has the following problems: (1) The melt extrusion system has large viscosity, poor process, high energy consumption, and it is difficult to form a smooth surface; (2) Mechanics of existing plastic-wood composite materials Performance, heat resistance, weather resistance, etc. need to be improved; (3) common plastic blending equipment is difficult to meet the requirements of high quality plastic wood products.
In response to these problems, Tsinghua University and the company formed a joint research team, conducted in-depth and systematic research, and developed a series of plastic-wood composite material production equipment and wood powder coating and extrusion technology.
The main feature of the technology is that the wood powder is coated with talc powder, and then processed into a plastic-wood composite material together with the waste plastic through a special plastic wood processing equipment. (1) Coating the surface of the fiber with ultrafine talc can reduce the internal resistance of the composite extrusion process, and improve the processing technology and improve the material performance. (2) Due to the addition of talc, the viscosity and energy consumption are reduced, and the mechanical and weather resistance and heat resistance of the material are improved. (3) The special profile extrusion die designed by computer-aided plastic mold analysis software can effectively improve the mechanical properties, dimensional accuracy and production efficiency of the product during the molding process. (4) The series of equipments are reasonable in design, compact in structure and simple in operation. The production process is controlled by computer. The degree of automation is high, pollution-free, low noise, high output per unit, and the extrusion speed reaches the international advanced level of similar products. The talc coated wood powder technology belongs to the original invention, and the processing system is at an advanced level in the same technology at home and abroad.
At present, 4 companies have adopted this technology. Through continuous improvement of technology, it will have a wide range of application targets and broad market prospects.
