本发明较优公开例中，所述表面装饰层附着在木质基材层的表面之上，厚度为0.1～5mm。所述表层装饰层为UV树脂层、PP装饰膜或浸渍耐磨装饰纸中的一种或任意二种，其中，UV树脂层为高耐磨UV树脂涂布而成；所述浸渍耐磨装饰纸为将装饰纸浸渍于混有耐磨料的三聚氰胺树脂或改性三聚氰胺树脂中，取出后干燥而成，所述耐磨料为180～240目的Al2O3粒子。
本发明较优公开例中，所述木质基材层的厚度为0.1～5mm，为多层胶合板或中高密度板。表面装饰层通过直接辊涂PUR胶粘或热压附着在木质基材层表面。
本发明较优公开例中，所述木质基材层的下表面通过冷贴环保耐水胶与木塑发泡层上表面粘合在一起。
本发明较优公开例中，所述防潮平衡层的厚度为0.1～5mm，为UV树脂层或浸渍胶膜纸。所述UV树脂层是将UV树脂通过辊涂并经紫外光固化在底部的木质基材层下表面，所述浸渍胶膜纸通过热压粘贴在底部的木质基材层的下表面。
本发明较优公开例中，所述底部的木质基材层上表面通过环保耐水冷贴胶冷压粘合在木塑发泡层的下表面。
有益效果
本发明所公开的木塑发泡层复合地板，表面装饰层具有高耐磨的特性，木塑发泡层有较好的保温性能，防潮平衡层具有优良的耐水、耐候性能，木质基材层为环保等级高的木质材料，环保耐水冷贴胶水为水性聚氨酯胶水。所公开的复合地板结构设计合理，具有低甲醛释放、耐用及保温性能优良的特性，是绿色节能环保的新型建筑装饰材料。有别于现有技术，本发明采用环保木质基材、木塑发泡材料、高耐磨装饰材料、环保胶黏剂、环保防潮平衡、UV树脂等制成，具有高耐磨、保温、环保防潮的优点。其生产工艺简单，适合工业化生产。
