In order to solve the problems of the technologies described above, a kind of wood-plastic composite floor of the utility model comprises sandwich layer, and wherein, described sandwich layer upper surface is fixed with a wooden cortex, and soffit is fixed with an end cortex.

Above-mentioned a kind of wood-plastic composite floor, wherein, described wooden cortex upper surface is provided with a ultraviolet processing layer.

Above-mentioned a kind of wood-plastic composite floor wherein, is provided with a wearing layer between described wooden cortex and the described ultraviolet processing layer.

Above-mentioned a kind of wood-plastic composite floor, wherein, cortex soffit of the described end is provided with a waterproofing course.

Above-mentioned a kind of wood-plastic composite floor, wherein, described sandwich layer is formed by wood powder and polyvinyl chloride compacting.

Above-mentioned a kind of wood-plastic composite floor, wherein, described wooden skin thickness is 1.5mm, the thickness of cortex of the described end is 1.5mm.

Adopt the novel wood-plastic composite floor board of said structure, because the sandwich layer on floor is formed by the composite material compacting of wood powder and polyvinyl chloride, water resistance is extremely excellent, expansion rate of water absorption is basically below 3%, wooden cortex and end cortex because the sandwich layer upper and lower surface is set up defences respectively, the original texture that has represented timber, outward appearance is beautiful, because the thickness of wooden cortex and end cortex is 1.5mm, water sucting thickness expands less, guaranteed that this floor has than the water resistance of pure wood floors excellence, good dimensional stability, therefore, can not be out of shape; Because wooden cortex upper surface is provided with a ultraviolet processing layer, not only make flooring look more beautiful, and floor surface serious defective can not occur, make the floor more durable, and better with people's tactility; In addition,, can make the water resistance on floor that further raising is arranged like this, can satisfy the requirement of high water proofing property, make the floor can be used for places such as bathroom and kitchen because cortex soffit of the described end is provided with a waterproofing course.
