[0002] Flame retardant and fireproof flooring is generally made of materials with flame retardant properties, with fiberboard, particleboard, plywood, etc. as the base material, and paint or impregnated paper as the finishing material. Through flame retardant treatment, a wood composite floor with a certain flame retardant grade and fireproof function is obtained to improve the fire safety of the floor.

[0003] However, although the current flame retardant and fireproof flooring has a certain fireproof effect, it is not perfect in waterproofing treatment, and the waterproof effect is average, and it cannot effectively and comprehensively isolate the water vapor from the ground and the air. In daily life, water vapor will not only return from the wet ground to the floor, corroding the floor, but also corrode the floor through the joints between adjacent floors; especially when mopping the floor, the water on the mop will flow down along the joints of the floor and penetrate into the floor, making the inside of the wood board damp, which is easy to breed bacteria and cause mildew to damage the board, affecting its flame retardant and fireproof effect and normal use.

[0011] Compared with the prior art, the beneficial effects of the utility model are:
