Abstract

The invention relates to the technical field of chemical production and in particular relates to a wood-plastic coextruded fabric. The wood-plastic coextruded fabric is prepared from the following raw materials in parts by weight: 30 percent to 60 percent of polyolefin resin, 5 percent to 20 percent of a polypropylene grafting material, 10 percent to 40 percent of reinforced resin and 1 percent to 10 percent of a functional auxiliary agent. According to the wood-plastic coextruded fabric, all components are organically compounded and a binding force between the prepared coextruded fabric and a wood-plastic core layer is great; the wood-plastic coextruded fabric has ultrahigh bonding strength; the covered wood-plastic core layer can be toughened; the wood-plastic weather resistance, corrosion resistance, high-temperature resistance, toughness and mechanical strength are improved.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a wood-plastic co-extruded fabric. Background technique [0002] Wood-plastic co-extruded fabric is a protective material that is coated on the surface of wood-plastic by co-extrusion process. Since wood-plastic products are exposed to outdoors for a long time, they are constantly eroded by rain, sun aging, and trampled by pedestrians, resulting in problems such as mildew, warping, cracking, pulverization, and wear. Layered fabrics help to improve the above problems and increase the service life of wood-plastic products. However, the coating materials currently on the market have low hardness and low bonding force with the wood-plastic core layer, and the coating material is easily detached from the wood-plastic core layer, which greatly limits the application of coating materials in wood-plastic products. . Contents of the invention [0003] The purpose of the p...
