Abstract

The invention discloses a method for improving the adhesion performance of a rolling type black rubber foxing glue piece for rubber shoes. Foxing main glue has sufficient hardness, shrinkage prevention performance and compatibility with adhesion glue by controlling the plastication degree of the main glue and the adhesion glue during the production process, so that the ducility, adhesion and durability of the adhesion glue are guaranteed, and the consistency of the vulcanization performance of the adhesion glue and the boxing glue is guaranteed through the control for vulcanization beginning point indexes of the adhesion glue and the boxing glue. The adhesion performance is greatly improved by controlling the using amount of composite resign for the formula of black adhesion glue. The method is simple and practicable, and low in cost and the using effect is good.

Description

technical field [0001] The invention relates to the field of rubber material preparation, in particular to a method for improving the bonding performance of calendered black rubber strips for rubber shoes. Background technique [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 performance of the enclosure glue, the bonding effect will be poor, the bonding strength will be insufficient, the flex resistance will be low, and quality problems such as the enclosure glue opening will occur, which will shorten the service life of the product. 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, mismatche...
