PVC co-extrusion foaming floor and preparation method thereof
The invention relates to a PVC co-extrusion foaming floor and a preparation method thereof, and belongs to the technical field of PVC foaming floors. The PVC co-extrusion foaming floor comprises a PVCfoaming core and a plastic surface layer, wherein the PVC foaming core comprises a first foaming layer, a second foaming layer and a skinning layer, the second foaming layer wraps the first foaming layer, the skinning layer wraps the second foaming layer, and all the layers of the PVC foaming core are integrally connected; the plastic surface layer wraps at least the upper surface of the skinninglayer; the first foaming layer is a low-density foaming layer, and the second foaming layer is a high-density foaming layer; and wood textures are formed in the plastic surface layer. According to the PVC co-extrusion foaming floor and the preparation method thereof, one-time forming is achieved through an improved foaming process, so that compared with a PVC foaming core in the prior art that the first foaming layer and the second foaming layer are not obviously distinguished and the skinning layer is thin, the PVC foaming core has the advantages of being clearer in structural hierarchy andhigher in overall strength; and the PVC foaming core is more suitable for wrapping the plastic surface layer.
本发明涉及一种PVC共挤发泡地板及其制备方法，属于PVC发泡地板技术领域。PVC共挤发泡地板，包括PVC发泡芯和塑料表层，PVC发泡芯包括第一发泡层、第二发泡层和结皮层，第二发泡层包覆第一发泡层，结皮层包覆第二发泡层，并且PVC发泡芯的各层一体连接；塑料表层至少包覆在结皮层的上表面；第一发泡层为低密度发泡层，第二发泡层为高密度发泡层；塑料表层上具有木材纹理。本发明通过改进的发泡工艺一次成型；使得本发明的PVC发泡芯相对于现有技术中第一发泡层和第二发泡层区分不明显，结皮层厚度薄的PVC发泡芯，具有结构层次更加分明、整体强度更高的优点；并且更加适宜塑料表层的包覆。
