Polymer-based wood plastic composites (WPC) refers to the pretreatment of plant fiber or powder (such as wood, bamboo, peanut shells, coconut shells, flax, straw, etc.) as the main component Reached more than 60%),green wood plastic material and the polymer resin matrix compound made of a new material. The material has many advantages of both plant fiber and polymer material, can replace wood,WPC flooring can effectively alleviate the shortage of forest resources in China, timber supply shortage of contradictions.

Its application is very broad, mainly used in building materials, automobile industry, the packaging of goods transport, warehousing, decorative materials and daily appliances and so on. As the renewable nature of plant fibers, can be environmental digestion,WPC outdoor wall panels so WPC is a very promising green materials, its production technology is also considered to be a viable and innovative technology. WPC wide range of uses, cheap, but to produce excellent performance in all aspects of the product is not easy.

The main reasons are: (1) because of containing a large number of hydrophilic groups - hydroxy, plant fiber has a strong polarity, and the common resin matrix is ??usually non-polar, non-hydrophilic, so the plant fiber and resin matrix The interfacial bonding strength is low,Composite Wood Outdoor Patio Flooring which affects the mechanical properties of WPC; (2) because of the hydrogen bond between the hydroxyl can form a strong interaction between plant fibers, making it in the resin matrix (3) The biodegradable color of the plant filler during the molding process, and the thermal degradation of the polymer material, the unsuitable compounding and the processing technology will lead to the degradation of the WPC performance.
