White adhesive for shoe upper coating sponge and preparation method thereof

Abstract

The invention discloses a white adhesive for shoe upper coating sponge. Water is used as a disperse medium. The adhesive is mainly used for gluing rubber footwear mouth coating sponge and shoe uppers. By the use of the adhesive, osmosis prevention performance of shoe uppers and mouth sponge can be raised. As use amount of macromolecular materials in the adhesive is reduced and use amount of a surfactant is increased, cloth cover soakage of the adhesive is enhanced. The surfactant material eliminates surface tension of the white adhesive for shoe upper coating sponge to compact cloth cover and makes the adhesive easily permeate into grain lien from the cloth cover to form a layer of adhesive slurry. Then, cloth fiber of shoe uppers is bound in the adhesive slurry, and the adhesive slurry firmly adheres to the shoe upper fabric. Macromolecules formed after water swelling of sodium carboxymethylcellulose has a bridging effect on loose fabric, the adhesive is prevented from permeating into gaps of loose cloth layers, and the adhesive is stacked on the cloth cover. Thus, the adhesive effect of the adhesive and foxing film is enhanced.

Description

technical field [0001] The invention relates to the field of rubber material preparation, in particular to a white adhesive for shoe upper wrapping sponge and a preparation method thereof. Background technique [0002] The upper of the rubber shoes is wrapped with a sponge adhesive, which is used to bond the upper surface of the rubber shoe and the sponge of the shoe upper, so that the sponge of the rubber shoe and the upper of the shoe form a firm whole. The main index for judging the performance of the shoe upper sponge adhesive is that after the rubber shoe upper surface cloth and the shoe upper opening sponge are bonded, there will be no debonding at the bonded part of the two, and there will be no separation between the two during the sewing process of the shoe upper. [0003] Under normal circumstances, the sponge adhesive glue of white shoes and rubber shoes is a solvent-based glue made of rubber compound rubber as the solute and an organic solvent as the solvent. The...
