Double-veneer oriented strand board and preparation method thereof

The invention discloses a double-veneer oriented strand board and a preparation method thereof. The double-veneer oriented strand board comprises a first layer, a base board layer and a second layer from top to bottom, wherein the first layer and the second layer are both made of melamine continuous laminated paper. The melamine continuous laminated paper is pressed and attached to the surface of a base plate, the surface of the prepared double-veneer oriented strand board is smoother and more attractive, the prepared double-veneer oriented strand board has very high physical and mechanical properties, meanwhile, the double-veneer oriented strand board is capable of effectively isolating strong permeation of water vapor, avoiding or reducing the release of formaldehyde of the board, and improving the household air quality, and is suitable for popularization and use. 本发明公开了一种双饰面定向结构刨花板及其制备方法，该所述双饰面定向结构刨花板由上至下包括第一层、基板层以及第二层；所述第一层和第二层的材料均为三聚氰胺连续层压纸。本发明将三聚氰胺连续层压纸压贴于基板的表面，制备得到的双饰面定向结构刨花板表面更为平整和美观，且具有很高的物理力学性能，同时，该
