Wuhan develops environmentally friendly wood-plastic composite materials

A few days ago, a kind of “eat” used plastics, treated “white pollution”, and used special wood fiber (such as sawdust, wood twigs) and plant fibers (such as clams, rice hulls, peanut husks, and plant stalks) Wood-plastic composite materials made of additives have been successfully developed by researchers of the Wuhan Institute of Modern Industrial Technology and become a new type of material that is made of plastic and wood.
The product is filled with thermoplastic resin in wood fiber and plant fiber, and at the same time, some related viscosity-enhancing and blending modifiers are added, and the plate, profile and pipe are made by extrusion to replace the corresponding wood products. In addition to the advantages of easy processing and molding of wood, the material also has the characteristics of high strength, corrosion resistance, insect resistance, moisture resistance, long service life, and reusability. The hardness of the material is 3 to 7 times higher than untreated wood, and the wear resistance is high. 4 to 5 times, the compressive strength of the grain is 2 times higher, and the compressive strength of the grain is 4 times higher. Due to its low water absorption, low hygroscopic expansivity, high thermal conductivity and thermal stability, and low thermal diffusivity, the product can be antistatic and flame retardant, and its cost is 40% to 60% lower than that of pure wood or plastic, which is a value-added use of wood. Expanded new ways.
