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. Quality problems such as rubber, rubber sole cloth delamination, rubber shoe skirt delamination, etc., resulting in low product qualification rate

Abstract

The invention provides a water-soluble adhesive and a preparation method thereof. The water-soluble adhesive is prepared mainly by natural latex, soft water, a vulcanizing agent, a vulcanization accelerator, a vulcanizing activator, a dispersant, anhydride casein, borax, a stabilizer, a wetting agent, ammonia and potassium hydroxide. In order to improve the performance of the water-soluble adhesive, carboxymethyl cellulose sodium, the wetting agent, an age inhibitor, an antifoaming agent and a mildew inhibitor also can be added; the obtained water-soluble adhesive is an environment-friendly material which is used for shoes, has the processing advantages of low energy consumption, non-toxicity, good processing property, simple operation and the like in the preparation process, strengthens self deterioration resistance, greatly prolongs the storage stabilization period of slurry, improves the intrinsic performance of the adhesive, and fundamentally realizes the demand of high adhesive strength on rubber shoes.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a water-soluble adhesive and a preparation method thereof. Background technique [0002] Adhesive glue for rubber shoes, also known as adhesive, commonly known as glue, its purpose is to bond the rubber shoes skirt and shoe upper, so that the rubber shoes skirt film and the shoe upper form a firm whole. The main indicator for judging the performance of the adhesive is the bonding strength between the rubber shoe skirt film and the shoe upper. The measured value of the bond strength between the rubber shoe skirt film and the shoe upper is often used to indicate the adhesive performance of the adhesive on the rubber shoes. [0003] Under normal circumstances, the adhesive mortar of rubber shoes is a solvent-based mortar that uses rubber compound rubber as the solute and an organic solvent as the solvent. The solvent-based mortar usually uses 120# gasoline or toluene as the solven...
