The invention discloses a novel antifungal wood-plastic cupboard sheet. The novel antifungal wood-plastic cupboard sheet is prepared from the ingredients in parts by weight: 70-90 parts of plastic matrix, 0.7-9 parts of composite antifungal agent, 20-30 parts of wood fiber powder, 28-35 parts of calcareous bulking agent, 6-10 parts of plasticizing regulator, 3-6 parts of environment-friendly stabilizer, 0.5-2 parts of lubricant, 5-7 parts of ACR processing aid, 1-2 parts of foamer and 0.1-0.5 part of tungsten carbide powder. The novel antifungal wood-plastic cupboard sheet disclosed by the invention has the following advantages that the wood-plastic cupboard sheet has antifungal property and can excellently resist fungi and prevent mildewing; an antifungal layer of an inner layer is relatively low in porosity and has relatively good waterproofing performance; the source of raw materials is wide, and the cost is low, so that the wood-plastic cupboard sheet is energy-saving and environmentally friendly and is an ideal bathroom decorative sheet for replacing ordinary density sheets and multi-layered sheets.
Description
technical field [0001] The invention relates to a wood-plastic board, more precisely, a novel antibacterial wood-plastic cabinet board and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a material made of wood powder, wood fiber or plant fiber filled thermoplastic polymer through high temperature and high pressure treatment. It has the advantages of both wood and plastic. Its main raw material is agricultural and forestry waste (such as waste wood, crops, rice straw, etc.) and thermoplastics. Since the wood fiber in the wood-plastic material cannot be completely covered by the plastic, and there is still a certain porosity in the material, in a humid environment, moisture can easily enter the wood fiber along the gap, causing the wood fiber to swell and become moldy, causing Wood-plastic materials are mildewed and corrupted, faded and discolored. Studies have found that the molds that cause mold mainly include Aspergillus nige...
