New technology of wood plastic material products

Wood plastic composite material is plastic raw materials and plant fiber mixed with a certain proportion, forming a material, has the advantages of wood and plastics, similar to the appearance of the wood and two processing capacity, low hygroscopicity, corrosion resistance and insect resistance, less maintenance, is a good substitute for outdoor application of wood plastic or metal materials.

Forming method of wood plastic composite materials are mainly extrusion molding, injection molding and hot pressing extrusion. Due to short processing cycle, high efficiency, wide application. The wood flour mixing structure is processed into profile extrusion industry active research topic. The extrusion molding process one step extrusion molding method and multi-step extrusion method of forming. In actual production, if wood materials or products with high water content and complex structure, the commonly used multi step extrusion molding, but because of the process, the production cost is high.

In recent years, progress has been made in wood plastic composite materials and processing technology, include the interface of wood plastic composite bonding and improve uniformity; more beautiful wood texture appearance; "more is not easy to fade in color; in order to improve the rigidity and durability of the coextrusion coating technology; in order to reduce the weight and cost to improve the foam products the development of the final performance.
