Water-based adhesive for toe caps and preparing method thereof

Abstract

The invention discloses a water-based adhesive for toe caps and a preparing method of it. The invention uses water as the dispersing medium to glue the toe caps and shoe sides with the adhesive, and the inventor reduces the amount of macromolecule materials in the adhesive and increases the amount of surfactant JDC, which improves the soakage of the adhesive to the cloth with a relatively compact surface. Allowing the adhesive to penetrate into the fabric, forming a layer of adhesive slurry, which unifies with the main adhesive on the surface, and then binding the fabric of the shoe sides to the slurry to make the slurry firmly adhere to the fabric. As for cloths that are of small knitting tightness and is thus rough and loose, the macromolecules formed after the carboxymethyl cellulose sodium swelling in water can prevent the adhesive from penetrating into the gaps between the loose cloth layers and increase the piling of adhesive on the cloth, and thus improves the bonding effect between the adhesive and the shoe rubber strips.

Description

technical field [0001] The invention relates to the field of adhesive material preparation, in particular to a water-based natural-color headband adhesive for shoes and a preparation method thereof. Background technique [0002] The upper toe cloth adhesive of rubber shoes is used to bond the upper surface of rubber shoes and the inner lining cloth of the toe cap, so that the inner lining cloth of rubber shoes and the upper form a firm whole. The main index for judging the performance of the upper toe cloth adhesive is that after the upper cloth of the shoe upper and the inner lining cloth of the toe cap are bonded, there will be no degumming at the bonding part of the two, and there will be no separation between the two during the sewing process of the upper. Snap the two together with your fingers. [0003] Under normal circumstances, the adhesive glue for the toe cloth of rubber shoes is a solvent-based glue with rubber compound glue as the solute and organic solvent as ...

AI Technical Summary

Problems solved by technology

Solvent-based glue has the disadvantages of difficult processing, high energy consumption, high cost, long processing cycle, and high toxicity. At the same time, it also has quality defects such as low initial adhesive strength and low final adhesive strength, which may easily lead to rubber shoe penetration during the production process. Glue and other quality problems, resulting in low product qualification rate

At the same time, it is flammable and has potential safety hazards
