Description

Technical Field

[0001] The utility model discloses a co-extruded hollow plastic wood fence board, which relates to a board and belongs to the technical field of composite materials and new materials. Background Art

[0002] Wood-plastic composite materials are made of low-value biomass fibers such as wood powder, crop straw powder, and rice bran powder as the main raw materials, mixed with plastics, and made through processes such as extrusion and molding. They have many advantages such as raw material resource utilization, product plasticization, environmental protection, cost economy, and recycling. As the advantages of wood-plastic products are increasingly recognized by people, their application scope is rapidly expanding. Their application fields involve many aspects such as municipal administration, gardening, transportation, packaging, entertainment, sports, and decoration. The product types are also becoming more and more abundant. One of the most widely used and widely used products is wood-plastic fence panels. Most traditional fence panels are wooden fence panels or metal fence panels. However, whether it is wooden fence panels or metal fence panels, there are certain shortcomings in the production or use process. For example, most wooden fence panels are solid panels, which are heavy, costly, and have complex processing processes. They are easy to age and crack, easy to change color, easy to be eaten by insects, and waste wood resources during production. Metal fence panels have relatively simple appearance and color, poor designability, high cost, bulky, inconvenient installation, and need to be treated with anti-corrosion and anti-rust. Plastic wood fence panels can overcome the shortcomings of traditional fence panels and are therefore popular in the market. However, the common plastic wood fence panels on the market have poor anti-aging effects, are heavy, and have high costs. Therefore, it is necessary to invent a new type of plastic wood fence panel to overcome the above shortcomings.

[0003] Co-extruded hollow plastic wood fence panels use two extrusion equipment to extrude raw materials of different formulas through different extruder heads, and then merge and extrude them together in a mold. The plastic wood fence panels obtained in this way have an internal and external layered structure, with a hollow plastic wood structure layer in the middle and an anti-aging layer on the outside. The co-extruded plastic wood fence panels obtained in this way not only maintain the characteristics of plastic wood materials such as high strength, corrosion resistance, good waterproof performance, and insect resistance, but also have good anti-aging performance on the surface layer, making them safer when used in open air environments and having a longer service life.
