Abstract

The intention discloses a mildew-proof wood plastic material which contains 50-60 parts of recycled high-density polyethylene (HDPE) plastics, 130-140 parts of wood powder, 20-30 parts of light calcium carbonate, 6-8 parts of coupling reagents, 1-3 parts of zinc stearate, 1-3 parts of ethylene bis stearamide (EBS), 1-3 parts of paraffins, 0.4-0.6 part of ultraviolet (UV) absorber UV-531, 0.4-0.6 part of antioxidant 1010, 3-4 parts of iron oxide red 110B, 0.7-0.9 part of iron oxide brown 66 and 0.6-0.8 part of carbon black 3113 according to weight. Moisture content of the wood powder is no more than 3%, and fineness of the wood powder is 60-80 meshes. A production method of the mildew-proof wood plastic material includes the following steps: (1) premix preparing; (2) semi-finished product pelleting material preparing and (3) extrusion molding. According to the mildew-proof wood plastic material and the production method thereof, the obtained mildew-proof wood plastic material cannot mildew when meeting water or being used in severe environments such as the humid environment for a long time.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a mildew-resistant plastic-wood material and a preparation method thereof. Background technique [0002] WPC, as the name suggests, is a combination of solid wood and plastic. It not only maintains the affinity of solid wood, but also has good moisture-proof, water-resistant, acid and alkali resistance, anti-fungal, anti-static, anti-moth and other properties. A series of wood-plastic composite materials produced from waste such as sawdust, straw, and waste plastics are gradually entering the fields of decoration and construction. At present, the main product is PVC wood-plastic material obtained by combining wood chips and PVC. However, due to the poor compatibility of the system after being mixed with wood powder, the wood-plastic material will suffer from long-term use under harsh environmental conditions such as water and humid environments. get mouldy.
