Description

Method for manufacturing plastic floor tile

Technical Field

The invention relates to the technical field related to plastic floor tile production, in particular to a manufacturing method of plastic floor tiles.

The manufacturing method comprises respectively taking three raw materials of a base layer 92, a printing layer 94 and a fabric layer 96 which are rolled into a bundle shape, laminating the three raw materials into bodies through a rolling laminating method, laminating the three raw materials with the base layer 92 by a printing layer back glue 942 arranged on the laminating surface of the printing layer 94, and laminating the three raw materials with the printing layer 94 by a surface layer back glue 962 arranged on the laminating surface of the fabric layer 96.

In order to overcome the problem of , manufacturers often use a corona process to solve the problem by continuously applying a high voltage electric shock to the surface of the transparent sheet 964 to be coated to oxidize and polarize molecules on the surface of the transparent sheet 964, and eroding the surface of the transparent sheet 964 by an ion electric shock to increase the adhesion capability of the surface of the transparent sheet 964.

Although the goal of increasing the adhesion of the transparent sheet 964 can be achieved through the corona process; however, the "corona" process is costly and complex and is often a problem in the industry.

In comparison with the plastic floor tile manufacturing process, the selection of the fabric layer 96 has problems of waiting time for the manufacturing process and storage pressure, so how to integrate the generation of the fabric layer 96 (the generation of the transparent sheet 964 and the bonding of the surface layer back glue 962) into the plastic floor tile manufacturing process without expensive and time-consuming corona process, thereby reducing the material cost and the storage pressure, which is a bottleneck to be overcome in the industry.
