Problems solved by technology

To achieve such a goal, the water-based adhesive can really be used to replace the solvent-based glue that uses rubber compound as the solute and organic matter as the solvent (such as 120# gasoline or toluene, etc.), to overcome the processing problems of the solvent-based glue. It has the disadvantages of high difficulty, high energy consumption, high cost, long processing cycle, and high toxicity, and overcomes the process defects of solvent-based mortar such as low initial adhesive strength and low final adhesive strength.

Abstract

The invention discloses a water-borne rubber cement for cotton canvas rubber shoe foxing bonding and a preparation method thereof. A combination of natural latex and pyridine-styrene-butadiene rubberlatex is adopted as the host material, a vulcanized and cross-linked adhesive, a bonded part and cotton canvas fiber form a high strength and uniform adherend, and the final bonding strength is high.The rubber cement has long-lasting surface stickiness, has low temperature requirement for the bonded part, and lowers the requirement of the bonded rubber material for thermal insulation performance.The three major quality problems of cotton canvas rubber shoes, i.e. lace delamination, base fabric disengaging and undersole delamination are effectively solved, and the quality defect of glue failure during use of cotton canvas rubber shoes can be thoroughly eliminated.

Description

technical field [0001] The invention relates to the technical field of rubber processing, in particular to a water-based glue for bonding cotton canvas rubber shoe skirts and a preparation method thereof. Background technique [0002] Adhesives are used to connect the rubber parts used in rubber shoes to the textile materials. The quality of the adhesives is directly reflected in whether the strips are glued during use. In terms of technical indicators, the bonding strength of the upper and the apron glue is usually used to indicate the bonding strength of the rubber shoes. However, in actual use, the ability of shoes with high adhesive strength to resist ungluing is not as good as people imagined. However, some rubber shoes with relatively low adhesive strength values ​​often do not produce glue opening. [0003] In the shoemaking process, cotton canvas has become one of the main materials for shoe uppers because of its easy availability. Generally, the adhesive of cotto...
