Manufacturing method of PVC floor tile, PVC floor tile and manufacturing equipment

Abstract

The invention discloses a manufacturing method of a PVC floor tile, the PVC floor tile and manufacturing equipment. The method comprises the steps that a first glass fiber layer and a second PVC layerare provided, the first glass fiber layer is embedded into the second PVC layer and partially exposed out of the second PVC layer, and a composite layer of the first glass fiber layer and the secondPVC layer is formed; a wear-resistant layer, a printing layer and a first PVC layer are provided, the wear-resistant layer, the printing layer, the first PVC layer and the composite layer of the firstglass fiber layer and the second PVC layer are stacked together from top to bottom to enable the first glass fiber layer to be located on the side, facing the first PVC layer, of the second PVC layer; and the wear-resistant layer, the printing layer, the first PVC layer and the composite layer of the first glass fiber layer and the second PVC layer are bonded into a whole through a hot-pressing bonding process, so that the wear-resistant layer. According to the manufacturing method of the PVC floor tile, when the PVC floor tile is pressed, the influence of the glass fiber layer on the printing layer can be reduced, and glass fiber grid marks are prevented from appearing on the printing layer.

Description

technical field [0001] The invention relates to the field of floors, in particular to a method for manufacturing PVC floor tiles, PVC floor tiles and manufacturing equipment for manufacturing the PVC floor tiles. Background technique [0002] With the improvement of living standards, people are increasingly using floor tiles to enhance the aesthetics and practical performance of buildings. Among floor tiles, PVC (Polyvinyl chloride; polyvinyl chloride) floor tiles are used as a new light-weight floor decoration material. become more and more popular. In order to enhance the dimensional stability and thermal expansion performance of PVC floor tiles, glass fiber mesh cloth is often added to PVC floor tiles. figure 1 Shown is a schematic cross-sectional structure diagram of PVC floor tiles in the prior art. like figure 1 As shown, PVC floor tiles generally include wear-resistant layer 91, printing layer 92, first PVC layer 93, glass fiber layer 94 and second PVC layer 95, we...

AI Technical Summary

Problems solved by technology

[0004] Yet in this manufacturing method, because the property of glass fiber is comparatively stable, is a kind of infusible and insoluble substance, when glass fiber is put between the first PVC layer 93 and the second PVC layer 95, glass fiber will hinder the first PVC layer 93 and the second PVC layer 95. The fusing between a PVC layer 93 and the second PVC layer 95 then causes the process of the printing layer 92 to move downwards to be hindered, and uneven fiberglass grid printing (see figure 1 The convex and concave parts on the surface of the middle printing layer 92), affect the pattern on the printing layer 92, and affect the appearance and performance of PVC floor tiles
