Abstract
The present invention provides a composite floor and a manufacturing method thereof. The composite floor comprises a coextrusion layer compression moulded by a coextrusion process. The coextrusion layer comprises a first PVC (polyvinyl chloride) equilibrium layer, a WPC (Wood/Plastic Composite) foaming layer, and a second PVC equilibrium layer sequentially arranged from top to bottom. In the composite floor of this invention, the WPC foaming layer is the main material layer, and thus the whole weight of the floor is reduced. The first PVC equilibrium layer and the second PVC equilibrium layer are arranged respectively at two sides of the WPC foaming layer so that the composite floor is more stable in performance. It is more friendly to environment and simple in manufacturing procedure to adopt the coextrusion process for compression moulding because of avoiding bonding using glue.
