Problems solved by technology

[0004] However, when applying adhesive at the joint of the upper and bottom of rubber shoes, no matter whether it is manual work or automatic application, the adhesive will inevitably leak out after application, and flow to the sole or overflow to the upper. After wrapping the side glue and vulcanizing , nor can it be completely wrapped, the adhesive on the sole and the upper is very sticky after vulcanization, causing the finished shoes to be easily stained with dust and impurities, which affects the service life and appearance, and is not conducive to sales

Abstract

The invention discloses a double-vulcanized outsole side wall adhesive for cloth rubber shoes and an application thereof. The adhesive contains standard glue, soaked glue, sulfur, an accelerant, activated zinc oxide, xylene resin, stearic acid, an anti-aging agent, rosin, calcium carbonate and lithopone. The invention aims to provide the double-vulcanized outsole side wall adhesive for cloth rubber shoes. By optimizing and adjusting the formula, high adhesion strength before secondary vulcanization can be ensured, and surface tackiness after vulcanization can be avoided, and the adhesive is stable in performance. According to rubber overshoes made by taking the formula as the adhesive, the adhesive overflowing residual shoe soles or uppers after vulcanization is not stringy.

Description

technical field [0001] The invention relates to an adhesive, in particular to a twice-vulcanized outsole side wall adhesive for cloth-covered rubber shoes and an application thereof. Background technique [0002] Rubber shoes are composed of two major parts, the upper and the sole, as well as auxiliary parts such as protection, reinforcement, and decoration. Depending on the variety, the material and shape are different, and its characteristics are cheap, easy to make, comfortable to wear and durable, and it is actually a good product among shoes. [0003] The production process of rubber shoes generally includes upper sewing, rubber and semi-finished product preparation, molding, vulcanization, etc. Its molding methods include lamination (ie lamination), molding, injection and cold bonding. Lamination and molding are generally done by laminating the various parts of the rubber shoes on the shoe tree according to certain requirements, and then using a vulcanization tank fo...
