Wood plastic composite

Wood plastic composite

With the strengthening of people’s awareness of environmental protection, calls for protecting forest resources and reducing the use of new wood are increasing. Recycling low-cost waste wood and plastics has become a common concern in industry and science, which has promoted and promoted wood plastic composites. Substantial progress has been made in the research and development of WPC (Wood Plastic Composite) material, and its application is also showing an accelerated development trend.

In recent years, with the depletion of global resources, the awareness of social environmental protection has increased, and higher requirements have been placed on the application of wood and petrochemical products. In this context, wood plastic composite materials can not only take advantage of the advantages of each component in the material, overcome the limitations of use caused by low wood strength, large variability and low elastic modulus of organic materials, but also make full use of Waste wood and plastic reduce environmental pollution.

As we all know, waste wood and agricultural fiber can only be burned in the past, and the carbon dioxide produced has a greenhouse effect on the earth. Therefore, wood processing plants are trying to find ways to convert them into new products with high added value. At the same time, plastic recycling is also the key development direction of plastics industry technology. Whether plastics can be recycled and reused has become one of the important basis for many plastic processing industries to select materials. In this case, wood plastic composite materials came into being. Governments and relevant departments of various countries have attached great importance to the development and application research of this environmentally friendly new material.

Thermoplastic wood plastic composite material is a modified thermoplastic material that is filled and reinforced with wood fiber or plant fiber, and is made by different processing methods such as hot-pressing compounding and melt extrusion. In the field of wood plastic composite materials, the current research hotspots are mainly focused on thermoplastics such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), wood powder, and plant straw powder. Plant seed shells and other wood powder as materials, composite materials made by extrusion, injection molding, and compression molding. From the perspective of production materials, the materials of wood plastic composite materials can be used various waste plastics, waste wood and crop residues.

Therefore, the development and wide application of wood plastic composite materials help to reduce the pollution of plastic waste, and also help reduce the environmental pollution caused by the incineration of agricultural waste. The production and use of wood plastic composite materials will not emit volatiles harmful to human health to the surrounding environment. The material itself can be recycled. It is a brand-new green environmental protection product and an ecologically clean composite material.
