[0002] At present, decorative panels (especially floors) are made of composite wood boards or solid wood boards. Whether it is a composite wood board or a solid wood board, it is easy for the board to be scratched during use, and when soaked in water stains, the board is prone to peeling and warping. Since the board is made of composite wood boards and solid wood boards, its own fire resistance is poor.

[0003] In recent years, with the development of science and technology, composite materials composed of fiber and resin have been widely used. The production principle is to soak the fiber-reinforced material in the resin and then process it into shape through high temperature. Fiber-reinforced materials generally use glass fiber, carbon fiber, aramid fiber and other materials, while resins use epoxy resin, phenolic resin, polyester resin and other materials. The prepared boards have the characteristics of light weight, high strength, corrosion resistance, waterproof and fireproof. Therefore, it is possible to consider using fiber-reinforced resin boards to replace transmission decorative boards. However, there is currently no production equipment on the market that can produce fiber-reinforced resin decorative boards. Summary of the invention
