The invention provides a high-heat-preservation high-breathability environment-friendly odorless wood plywood and a preparation method thereof. The wood plywood is formed by stacking multiple layers of veneers and multiple layers of bonding films in a crossed mode, the multiple layers of veneers are prepared from a transparent wood-plastic composite material, the multiple layers of bonding films are prepared from high-density polyethylene films, and the transparent wood-plastic composite material comprises a delignified recyclable wood fiber filler, polymethyl methacrylate, polyol or ether glycol, 2,2'-azobis(2-methyl propionitrile), tetraethyl orthosilicate, cyclohexane, n-amyl alcohol, hexadecyl trimethyl ammonium bromide and urea. The wood-plastic composite material used in the invention is subjected to a lignin removal process, and then a phase-change heat storage material grafted polymethyl methacrylate copolymer of the radial mesoporous silica loaded polyethylene glycol permeates into a pore space to reduce light scattering, so that the absorption efficiency of heat energy brought by light energy is further enhanced, more heat energy can be released when the environment temperature is reduced, and a good heat preservation effect is achieved.
本发明提供一种高保温高透气环保无味木胶板及其制备方法，木胶板包括多层单板与多层粘合薄膜交叉叠放组成，多层单板由透明木塑复合材料制备而成，多层粘合薄膜由高密度聚乙烯薄膜制备而成，透明木塑复合材料，包括脱木质素可回收木质纤维填料、聚甲基丙烯酸甲酯、多元醇或醚‑二醇、2,2'偶氮二(2‑甲基丙腈)、正硅酸四乙酯、环己烷、正戊醇、十六烷基三甲基溴化铵、尿素。本发明所使用的木塑复合材料通过脱木质素过程，然后通过用径向介孔二氧化硅负载聚乙二醇的相变蓄热材料接枝聚甲基丙烯酸甲酯共聚物渗透孔隙空间来减少光散射，进一步加强了对光能所带来的热能的吸收效率，能够在环境温度下降时释放更多的热能，起到了良好的保温效果。
