[0002] Wood-plastic board (WPC) is a high-tech, green and environmentally friendly new decorative material made by mixing wood (cellulose, plant cellulose) as a base material with thermoplastic polymer materials (plastics) and processing aids, and then heating and extruding it into a mold. It combines the performance and characteristics of wood and plastic, and is a new composite material that can replace wood and plastic. When preparing WPC, since it is generally necessary to pre-set corresponding guide rails on the ground for installation, and then assemble the WPC panels onto the guide rails for assembly, but since WPC panels are mostly assembled by bolts or clamps during assembly, if a single WPC panel is damaged, it is not convenient to quickly disassemble and assemble the WPC panel and the guide rails for replacement.
