背景技术Background technique
木塑地板是用木粉、竹粉、秸秆等天然植物纤维与聚乙烯、聚氯乙烯等热塑性树脂和加工助剂按照一定的比例混合后通过挤出成型、注射成型等加工方式制成的板材，其中热塑性树脂可以使用废旧回收塑料，植物纤维可以使用生物质废弃物。该材料兼有塑料和木质材料两种材料的性能特点，在一定程度上能够替代塑料和木质材料，具有防水、防潮、防虫、加工性好、安装简单、尺寸稳定性好等优点。但木塑/地板纹理效果差、耐磨性差和减震性差等缺点也比较明显，可以通过与其他材料复合进行改性，且目前木塑地板使用的塑料是石油基塑料，为不可再生资源，且降解性差，对环境不友好。Wood-plastic flooring is made of wood flour, bamboo flour, straw and other natural plant fibers, polyethylene, polyvinyl chloride and other thermoplastic resins and processing aids in a certain proportion, and then processed by extrusion molding, injection molding and other processing methods. Among them, thermoplastic resin can use waste recycled plastics, and plant fiber can use biomass waste. The material has the performance characteristics of both plastic and wood materials, and can replace plastic and wood materials to a certain extent. It has the advantages of waterproof, moisture-proof, insect-proof, good processability, simple installation, and good dimensional stability. However, the disadvantages such as poor texture effect, poor wear resistance and poor shock absorption of wood plastic/floor are also obvious. It can be modified by compounding with other materials. At present, the plastic used in wood plastic flooring is petroleum-based plastic, which is a non-renewable resource. Moreover, it has poor degradability and is not friendly to the environment.
专利号CN201720477960.6公开了一种生物可降解木塑复合地板，该实用新型专利针对木塑地板的技术现状，虽然可以进行部分生物降解，但是地板的耐磨抗刮性能，耐用性能大大削弱，同时无法解决细菌腐蚀地板的问题。Patent number CN201720477960.6 discloses a biodegradable wood-plastic composite floor.
