COMPOSITE FLOOR AND PREPARATION METHOD THEREFOR
The present invention provides a composite floor and a manufacturing method thereof. The composite floor comprises a coextrusion layer compression moulded by using a coextrusion process. The coextrusion layer comprises a first stone-plastic layer, a stone-plastic foaming layer, and a second stone-plastic layer sequentially arranged from top to bottom. In the composite floor of the present invention, the stone-plastic foaming layer is used as the main material layer, which reduces a whole weight of the floor; and the first stone-plastic layer and the second stone-plastic layer are arranged at two sides of the stone-plastic foaming layer, respectively, so that the composite floor is more stable in performance. It is more friendly to environment and simple in manufacturing procedure to use the coextrusion process for compression moulding because of avoiding bonding using glue. Use of the coextrusion process makes various layers bond more compact, and little delamination and warpage due to effect of environmental changes may occur. Furthermore, the composite floor of the present invention is low in expansion rate, low in shrinkage rate, excellent in performance and long in service life.
