Description

Technical Field

[0001] This utility model relates to a type of board material that is resistant to seawater corrosion and belongs to the field of composite materials and new materials technology. Background Technology

[0002] Wood-plastic composites, made primarily from low-value biomass fibers such as wood flour, crop straw powder, and rice husk powder, are mixed with plastics and manufactured through extrusion, molding, and other processes. They offer numerous advantages, including resource utilization of raw materials, product plasticity, environmental friendliness, cost-effectiveness, and recyclability. As the advantages of wood-plastic products become increasingly recognized, their applications are rapidly expanding, encompassing municipal engineering, landscaping, transportation, packaging, entertainment, sports, and decoration, among others. Product types are also becoming increasingly diverse, including flooring, wall panels, skirting boards, hanging boards, pergolas, grape trellises, Great Wall boards, fence boards, handrails, railings, racks, shelves, pallets, tables and chairs, basketball backboards, and housing. Wood-plastic flooring has the largest application volume and widest usage, particularly for outdoor applications. Outdoor applications for wood-plastic flooring are numerous, with seaside boardwalks and docks being potential important locations. However, the potential corrosive effects of seawater or the air environment near the sea on wood-plastic flooring in these locations cannot be ignored. Conventional wood-plastic composite (WPC) flooring has a high plant fiber content, making it susceptible to corrosion when used near the sea, resulting in a short lifespan and requiring frequent maintenance or even replacement. To overcome this shortcoming, it is essential to invent a seawater-resistant WPC flooring that fully utilizes the advantages of WPC materials, such as water resistance, aging resistance, low cost, high strength, and light weight, thereby extending the lifespan of WPC flooring.
