Abstract

The invention specifically discloses an outdoor wood-plastic co-extruded fabric, belonging to the technical field of materials. The outdoor wood-plastic co-extruded fabric comprises the following rawmaterials by weight: 60-70 parts of straw, 40-50 parts of pine powder, 40-60 parts of polyethylene, 10-20 parts of polyvinyl chloride, 30-50 parts of modified starch, 1-3 parts of maleic anhydride grafted polyethylene, 1-3 parts of a lubricant and 0.1-1 part of an antioxidant. The outdoor wood-plastic co-extruded fabric has good water resistance. Experiments in embodiments of the invention prove that the outdoor wood-plastic co-extruded fabric has low water absorption rate, so reduction in service life caused by water absorption of the outdoor wood-plastic co-extruded fabric can be effectivelyprevented.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to an outdoor wood-plastic co-extrusion fabric. Background technique [0002] Wood-plastic composite (WPC) is a new type of composite material that has emerged in recent years. At present, the common wood-plastic composite materials are polyethylene, polypropylene and / or polyvinyl chloride and wood powder, rice husk, straw and other waste materials. Plant fibers are used as raw materials, and composite materials are made by different processing methods such as hot pressing compounding and melt extrusion. Mainly used in building materials, furniture, logistics packaging and other industries. The board formed by hot extrusion of wood-plastic composite material is called extruded wood-plastic composite board. [0003] With the wide application of wood-plastic composite materials, more and more wood-plastic composite materials are used in outdoor building materials, but one of the p...
