Abstract

The invention discloses a novel water-based adhesive for polyester filament canvas shoes and a preparation method thereof. A combined body of natural latex and an environment-friendly adhesive is usedas a main body material, and molecules of the latex are basically kept in the original shape, so that the higher initial adhesion capacity of the novel water-based adhesive for the polyester filamentcanvas shoes is ensured; asthe rubber polymer does not change, the vulcanized and cross-linked adhesive and an adhered adhesive part form a high-strength unified body and have relatively high final adhesion strength, so that the requirement on the surface viscosity of the adhered adhesive part is not high, the requirement on the temperature of the adhered adhesive part is low, and the requirementof an adhered adhesive material on the thermal insulation property is reduced. Due to the fact that the initial bonding force and affinity with the adhered adhesive part are improved, plastic flowingof molecules on the bonding surface of the adhesive part in the initial stage of high-temperature vulcanization is prevented, the adhesive part and the upper are firmly bonded together through the adhesive, and therefore the three quality problems of lace delaminating, base cloth disengaging and outsole elastic edges of the rubber shoes are effectively solved.

Description

technical field [0001] The invention relates to the technical field of rubber processing, in particular to a novel water-based adhesive for polyester filament canvas shoes and a preparation method thereof. Background technique [0002] The main indicators for judging the performance of the adhesive used in rubber shoes are the bonding strength between the rubber shoe skirt glue and the shoe upper and the peeling damage state during the measurement of the glue strength. The adhesive performance of rubber shoes is good or bad, and the peeling damage state is used to assist in judging the quality of the adhesive. [0003] Usually, the adhesive mortar of rubber shoes is a solvent-based mortar that uses rubber compound rubber as the solute and organic matter as the solvent. The solvent-based mortar usually uses 120# gasoline as the solvent, and the main raw material of the glue is natural rubber. Rubber mixing and related compounding agents. Solvent-based glue has the disadvant...
