Aiming at the shortage of wood resources and the demand for comprehensive resource utilization in China, this project developed a novel structural wood-plastic composite material after 8 consecutive years of industry-university-research collaborative research, supported by the National Natural Science Foundation of China and the "948" Program of the former State Forestry Administration (now National Forestry and Grassland Administration). The project has established 3 core technologies, secured 3 national invention patents and 6 utility model patents. Over 50 novel eco-friendly products under 10 categories have been developed for two major application scenarios: outdoor structural materials and architectural decoration materials.

This material is a recyclable, multi-purpose novel eco-friendly material prepared by treating wood flour via special processes, blending it with a certain proportion of plastics, and then performing extrusion molding, based on polymer interfacial chemistry theory and plastic filling modification technology. One of the core technologies of this project is establishing a compatibility system between wood and plastic interfaces, forming an interfacial layer with excellent composite performance between wood and plastics. Another core technology is the invention of extrusion molding technology for polypropylene (PP)-based wood-plastic composites with wood flour content exceeding 60%, as well as the manufacturing technology of wood-plastic materials reinforced by organic fiber prestressing. Polymer fusion technology and fiber toughening technology are adopted to improve the impact resistance of wood-plastic composites, and multiple functional serial products have been developed.

This technology was awarded the achievement certification of key scientific and technological projects by the National Forestry and Grassland Administration in 2006 (Document No. Linkeyanzi (2006) No. 40). The project *Development and Research of Wood-Plastic Composite External Wall Insulation Panels* carried out on the technical platform of this project obtained scientific and technological achievement certification from Qingdao Science and Technology Bureau (Jianzi (2007) No. 053), and was simultaneously recognized as a high-tech product by Qingdao Science and Technology Bureau (Qingkegaozi (2007) No. 10).

The technology of this project has been successfully industrialized, with a scaled production capacity of 7000 tons per year and an output value of 100 to 120 million yuan realized at Qingdao Huasheng High-tech Development Co., Ltd. The products have been applied to key projects including Beijing Olympic venues, Shanghai World Expo, and the construction of affordable housing demonstration communities in Qingdao under the Ministry of Housing and Urban-Rural Development, and exported to Japan, Australia and other countries, with favorable market feedback. This technology features raw material recycling, environmentally friendly application, cost-effectiveness and recyclability, which fully embodies a series of advanced concepts such as resource utilization, health and environmental protection, conservation and substitution, and circular economy. Adopting an enterprise-led, market-oriented, industry-university-research combined model for promotion and demonstration, this project aims to guide China's wood processing industry towards high-tech, high-value-added novel materials and products, enhance the productivity of the wood industry, and achieve the goals of resource conservation and ecological environment improvement.
