Substrate material of plasticized fibrous laminated board

The utility model relates to a substrate material of a plasticized fibrous laminated board. The existing composite wood floor is easy to bend, twist, camber and deform, has poor flame resistant properties, and is not favorable for environment protection and the ecological balance. Therefore, the substrate material of a plasticized fibrous laminated board comprises substrate plates, and is characterized in that at least one layer of substrate plate is laminated and solidified via the immersion in the resin. The substrate plate can be a paper plate, and can be non-woven or fibrous cloth. The substrate material of a plasticized fibrous laminated board has fireproof performance, and reduces the required quantity of lumber; after the surface is stuck with a lumber thin sheet, the surface has no swelling-shrinkage change after the change of the temperature and the moisture. The utility model is widely suitable for the manufacturing process of various composite wood floors.
