With the gradual decrease of forest resources and the sharp rise of the demand of boards, in order to meet the market demand, vinyl board is beginning to appear on the market, and in order to make the surface of the vinyl board have good aesthetic property, a layer of surface bonding material is generally adhered on the surface of the vinyl board, so that consumers can conveniently choose to purchase the vinyl board. The surface bonding material has three bonding modes of PVC color film, wear-resistant wood sheet and melamine impregnated paper at present. The wood sheet has strong texture and good visual aesthetic degree, but has poor wear resistance, and if the wear resistance is required to be improved, various paint processes are required, so that the process is complex, and the flame retardant property and the waterproof property are extremely poor. The melamine impregnated paper can achieve very strong wear resistance after being cured and molded, but the texture and the visual attractiveness are poor, and because the surfaces of base plates such as polyester plywood, vinyl material plates and the like are smooth, the traditional melamine impregnated paper cannot be directly molded with the vinyl material in a direct pressing and pasting mode, multiple processes are needed for secondary molding, and the production continuity and the mass production capacity are poor; in order to obtain a surface bonding material with strong texture, good visual aesthetics, good wear resistance, water resistance and flame resistance, researchers began to research to combine melamine glue and veneer together to obtain melamine glue impregnated veneer. However, the existing melamine impregnation process mainly aims at paper materials, and when the melamine impregnation process is used for impregnating wood veneers, on one hand, the wood veneers are independent and cannot be continuously impregnated, so that the production efficiency is extremely low; on the other hand, the quality of the finally obtained finished product of the melamine impregnated veneer is poor, and the wear resistance, the waterproof and flame retardant properties of the finished product cannot meet the use requirements; and when the melamine impregnated wood veneer is bonded with the vinyl material, the wood veneer needs to be pressed for many times, and cannot be formed at one time, so that the pressing process is troublesome. Therefore, the prior art has the problems of low production efficiency, poor product quality and more complex subsequent pressing and pasting process.
