Description

Technical Field

[0001] This utility model relates to a type of wood-plastic composite profile resistant to seawater corrosion, belonging to the field of composite materials and new materials technology. Background Technology

[0002] Profiles are objects with a certain geometric shape made of iron, steel, plastic, or other materials with a certain strength and toughness through processes such as rolling, extrusion, and casting. They can be used alone or further processed into other manufactured products and have been widely used in building structures, manufacturing and installation.

[0003] Wood-plastic composites, made primarily from low-value biomass fibers such as wood flour, crop straw powder, and rice bran powder, are mixed with plastics and processed through extrusion and molding. They offer numerous advantages, including resource utilization of raw materials, product plasticity, environmental friendliness, cost-effectiveness, and recyclability. Using wood-plastic composites to manufacture profiles not only meets the need for multi-functional profiles but also fully leverages the advantages of wood-plastic composites, making it a significant choice.

[0004] Currently, wood-plastic composite (WPC) products are widely used in construction and decoration, municipal engineering, packaging and transportation, and other fields. Product types include wall panels, skirting boards, flooring, pergolas, wall panels, handrails, guardrails, racks, and shelves. Many products can be made from WPC profiles, but when these products are used in special environments, such as seaside boardwalks and docks, the corrosive effects of seawater or the seaside air cannot be ignored. Conventional WPC products have a high plant fiber content, making them susceptible to corrosion at sea, resulting in a shorter lifespan and requiring frequent maintenance or even replacement. To overcome this deficiency, it is essential to invent a seawater-resistant WPC profile that fully utilizes the advantages of WPC materials, such as waterproofing, aging resistance, low cost, high strength, and light weight, to extend the lifespan of products made from it, such as WPC flooring, WPC edge banding, WPC connectors, and WPC guardrails.
