Preparation method of hot curing emulsion slurry for integration of rubber shoe upper and sole

Abstract

The invention discloses a preparation method of hot curing emulsion slurry for the integration of a rubber shoe upper and a sole, which comprises the steps that: KOH solution, nekal BX solution, penetrant JFC solution and the mixture of stabilizer H and polyacrylamide are prepared and are uniformly mixed with natural rubber latex to prepare the hot curing emulsion slurry for the integration of the rubber shoe upper and the sole. Compared with traditional latex, the preparation method greatly improves the stability and improves the working efficiency and reduces the consumption of an emulsion slurry brush, so that the emulsion slurry brushing performance is improved, the slurry which is brushed on the upper is increased, the emulsion slurry is easier to dip by the emulsion slurry brush and the emulsion slurry cannot easily fall off, and the brushing heights are easier to maintain consistent, the applied slurry is increased and the attraction is improved; and the adhesion of the upper and the sole is significantly improved, so that the quality defect of the product that the glue of an enclosing strip is cracked when the product is in use is reduced.

Description

technical field [0001] The invention relates to a preparation method of glue for bonding rubber shoes, in particular to a preparation method of vulcanized latex paste for bonding uppers and soles of rubber shoes. Background technique [0002] In the preparation process of rubber shoes, the combination of the cloth upper of the rubber shoes and the rubber sole is usually connected by using a rubber skirt as the middle link, and the bonding between the upper, the skirt and the outsole was used before the 1980s. A natural rubber made of gasoline mortar, but after the 1980s, it was replaced by a low-toxicity, low-cost natural latex. Concentrated natural latex, rubber accelerator, latex stabilizer, latex thickener, latex penetrant, inorganic filler, colorant and other components are commonly used at home and abroad; in terms of processing technology, ball mills or rubber mills are generally used. The sand mill grinds and emulsifies water-insoluble accelerators, colorants, reinfo...

AI Technical Summary

Problems solved by technology

Some disadvantages of this kind of latex formula are: under normal circumstances, the amount of glue on the upper is small, which is not as beautiful as gasoline glue, and after some consumers use the rubber shoes made of gasoline glue for a long time, the amount of glue sizing tends to decrease. The more the bottom is bonded, the better the product will be glued. Therefore, based on the above considerations, rubber formulation designers often reduce penetrants, increase the amount of sodium carboxymethyl cellulose or inorganic fillers in latex formulations to increase sizing As a result, not only the thickening and sizing effect is difficult to achieve, but also the stability of the latex is often greatly affected, the operation difficulty of the glue brushing workers increases, and the bonding strength of the bottom will also decrease or Tends to an unstable situation
