Step six: gluing the base material board, pasting the decorative board on the base material board, performing pressing treatment, and pressing by using a hot press, wherein the pressure is 25Kg/cm2, the pressing temperature is 120 ℃, and the pressing time is 60s, so as to obtain the crude product of the composite solid wood floor.
Step seven: and (3) processing and molding the coarse product of the composite solid wood floor by adopting a woodworking four-side planer and a double-end machine, and then performing UV paint roller coating and UV secondary irradiation to prepare the stone-plastic solid wood composite floor.
According to the invention, the surface of the wood-skin floor is good in wear resistance, stain resistance and scratch resistance, meanwhile, the attractiveness of the floor is improved, the defects of poor scratch resistance, poor wear resistance, poor stain resistance and poor moisture resistance of the surface of the existing composite floor are effectively overcome, meanwhile, the attractiveness of the floor is improved, and the appearance of the bottom plate is higher. And the base material is made of calcium magnesium powder and PVC powder, does not contain harmful substances such as heavy metal, formaldehyde and the like, is a 100% green environment-friendly floor, and is deeply popular with the majority of users.
