    The present invention relates to a composite floor and its method of manufacture. The composite floor comprises a compression molded coextrusion layer (1) using a coextrusion process. The coextrusion layer (1) comprises, from top to bottom, a first stone-plastic layer (11), a main stone-plastic foamed layer (12), which reduces the overall weight of the floor, and a second layer of stone-plastic (13). The performance of the composite floor is more stable since the first and second stone-plastic layers (11, 13) are disposed on both sides of the expanded stone-plastic layer (12). The coextrusion process makes it possible to avoid the use of an adhesive, to make the various layers more compact and to minimize delamination and warping. In addition, the composite floor has a low expansion ratio, a low shrinkage rate, excellent performance and a long service life.

    COMPOSITE FLOOR AND MANUFACTURING METHOD THEREOF
    The present invention relates to the field of floor technologies and, more particularly, a composite floor and its manufacturing process.
    A polyvinyl chloride (PVC) floor is a floor made using polyvinyl chloride as the main raw material and adding auxiliary materials, such as fillers, plasticizers, stabilizers, dyes and more. An ordinary PVC floor has a multilayer structure, generally comprising a wear-resistant layer, a layer of printing film, an intermediate layer of material, a layer of base material, etc. Depending on the materials of the main layers, PVC floors are divided into wood-plastic floors and stone-plastic floors. The middle layer of material and the base material layer of the stone-plastic floor often contain stone powder and PVC as the main materials, the density of which is relatively high, therefore the floor is relatively heavy, which does not facilitate the use of the floor. The middle layer of wood-plastic floor material generally contains wood flour and PVC as the main materials. Therefore, the overall weight of the wood-plastic floor is relatively low. In addition, the base material generally contains wood flour as the main material, which provides a noise reduction effect. The layers of current wood-plastic floors are generally bonded with an adhesive, which is liable to give an unstable bonding and which requires a complex manufacturing process and a higher labor cost. During the process of use, affected by the temperature and humidity of the environment, the adhesive between each layer is likely to lose its effectiveness and to come off. In addition, the wood-plastic floor is not resistant to high temperatures, and it begins to deform when the temperature is above 50 ° C. A warping 2 mm permanently makes the floor unusable and leads to a short service life.
