Eco-wood composites, referred to as wood-plastic composites (WPC), are composites made primarily of wood or cellulose-based materials and plastics. The fiber part was originally made of wood flour as the main raw material. In recent years, it has gradually expanded to other plant fiber materials, such as bamboo powder, rice husk, wheat straw and cotton stalk, which are rich in natural plant fiber materials. The plastic part is made of thermoplastics, mainly polyethylene (PE), polypropylene (PP) and other polyolefins and polystyrene (PS), polyvinyl chloride (PVC) including new materials, recycled materials and a mixture of the two. material. A reversible recycling multi-purpose green environment-friendly material made of various plant fibers and various plastics as main raw materials through a certain process. In practical applications, eco-wood composites can produce products with different properties and shapes according to user and market demand. Since the 1990s, eco-wood composites have been used in various fields as alternative solid wood materials.
Because the ecological wood composite material has good weather resistance and strong aging resistance, the ecological wood furniture has a long service life in the outdoor. From the economic point of view, eco-wood composites have low loss, paint-free and maintenance-free. Therefore, eco-wood outdoor furniture has been recognized by many countries and is gradually replacing the use of wood in outdoor furniture.
