Manufacturing method of plastic floor tile

Abstract

The invention provides a manufacturing method of a plastic floor tile. The manufacturing method comprises the following steps: mixing raw materials; plasticizing; extruding; extruding through using a T-shaped mold; rolling to form sheets; performing preheating two times; rolling and attaching; performing cooling two times; trimming; tempering; die-cutting, wherein a bottom surface layer and a substrate raw material are extruded and adhered in coordination with the T-shaped mold after being subjected to raw material mixing, plasticization and extrusion respectively and then rolled to produce sheets so as to obtain a composite bottom surface layer having the thickness same with that of a product; in addition, after a surface layer is preheated for two times, combining a printing layer and the composite bottom surface layer in sequence, so that the three layers are attached through rolling; preheating the surface layer and the composite bottom surface layer to adhesion temperature by using the rolling wheel with a heat source; attaching the surface layer, the printing layer and the composite bottom surface layer closely through the rolling wheel to form a semi-finished plastic floor tile product; finally performing two-time cooling, trimming, tempering and die-cutting on the plastic floor tile semi-finished product, shaping the semi-finished plastic floor tile product and cutting the semi-finished plastic floor tile product into ones of a finished product with required size specification.

Description

technical field [0001] The invention relates to a manufacturing technology of plastic floor tiles, in particular to a manufacturing method of plastic floor tiles which can increase the thickness of the fabric layer and increase the benefits of product pressure resistance and wear resistance. Background technique [0002] At present, plastic floor tiles are mainly made of plastic materials, and different decorative patterns can be provided according to market demand, and plastic floor tiles have better insulation effect due to their material characteristics, and plastic floor tiles have the advantages of low cost and DIY application, plus It has the advantages of being waterproof and does not require special maintenance, so it is widely used as a floor in various occasions. [0003] The structure of conventional plastic floor tiles, please refer to figure 1 As shown, it is a schematic cross-sectional view of a known plastic floor tile. In the figure, a conventional plastic ...

Problems solved by technology

However, the market demand and requirements continue to improve, and the thickness of the surface adhesive layer of the previous patent obviously cannot satisfy high-end consumers. In order to make the surface adhesive layer thickness of plastic floor tiles more perfect, an innovative manufacturing method is proposed again.
