In today's society, the design and construction of outdoor space are increasingly valued, among which the choice of materials is particularly critical. With its unique advantages, plastic wood materials have gradually become the best choice of many outdoor projects. This paper will explore all aspects of plastic wood materials from many angles, including its basic concepts, production process, main characteristics, application field and future development trend, aiming to provide readers with a comprehensive and practical knowledge science. Plastic wood material, called Wood-Plastic Composites (WPC), is an innovative building material made by mixing natural wood fibers with a plastic polymer. This combination not only retains the natural appearance and feel of the wood, but also gives the durability and low maintenance characteristics of the product plastic. Specifically, WPC is a new type of green and environmental protection material made of about 50% wood powder, rice husk, straw and 50% thermoplastic such as PE and PP after special process. In terms of production process, the production process of plastic wood materials usually includes raw material preparation, mixing, granulation, extrusion molding and post-processing steps. First, the natural wood fibers are dried and crushed, and the plastic particles are mixed in specific proportions and heated, melted, extruded, and finally cooled and cut through the double screw extruder. In this process, different additives can be added to improve the performance of the material. When it comes to the main characteristics of plastic wood materials, we have to mention its excellent environmental performance. As a renewable resource utilization product, plastic wood materials reduce the dependence on the original forest, and will not produce harmful substances in the process of use, helping to protect the environment. In addition, it also has good water resistance, corrosion resistance, moth prevention and other characteristics, making its excellent performance in the outdoor environment. It is worth mentioning that high-quality plastic wood materials, such as those provided by Oakio brand, have a 20-year warranty commitment, which undoubtedly provides users with long-term quality assurance. What scenarios are plastic wood materials suitable for? In fact, due to its excellent physical properties and aesthetics, plastic wood materials are widely used in urban parks, resorts, golf grounds, school playgrounds and other occasions. For example, in the Shanghai Yanan Golf Club, Oakio fully demonstrated the potential of the material in high-end leisure places; and in the Dali Group Shawan Resort, the old plastic wood platform was renovated to prove the reuse value of plastic wood materials. Whether in new construction or renovation projects, plastic wood materials can provide satisfactory solutions. With the progress of science and technology and the development of society, people's demand for green building materials is increasing day by day. Therefore, the market prospect of plastic wood material is very broad. It is expected that in the next few years, with the reduction of production costs and the further improvement of technology, plastic wood materials will be applied in more fields. At the same time, government support for sustainable development will also promote the development of the industry. In the long run, plastic wood materials are expected to build an eco-friendly society
