Problems solved by technology

[0002] In the process of rubber shoes production, the method of pasting the strip and the upper is generally to bond the strip film directly with the adhesive. In order to achieve a good bonding effect, the strip rubber must have a high enough glue content. Otherwise, due to insufficient surface viscous properties of the enclosing strips, the bonding effect will be poor, the bonding strength will be insufficient, the flex resistance will be low, quality problems such as enclosing strips will be opened, and the service life of the product will be shortened.
However, the improvement of the glue content, although a good bonding effect is obtained, will greatly increase the cost of the glue material, resulting in excess functions of the enclosure, mismatched product performance, and unsatisfactory economic performance.

Abstract

The invention discloses a method for improving the fit performance of a calendering type rubber edge strip adhesive sheet for rubber shoes. According to the invention, by controlling the plastication degree of main rubber and fit rubber in the production process, the edge strip main rubber has sufficient hardness and contraction prevention performance as well as the compatibility with the fit rubber, the malleability, viscosity and durability of the fit rubber are ensured; by controlling indexes of vulcanization starting point of the edge strip main rubber and the fit rubber, the consistent vulcanization performance of the fit rubber and the edge strip main rubber is ensured. The method for improving the fit performance of the calendering type rubber edge strip adhesive sheet for rubber shoes is simple and feasible, is low in cost, and has a good using effect.
