Abstract

The invention discloses an environment-friendly type high-bonding heat-vulcanization rubber overshoes water-emulsion adhesive and a preparation method thereof. According to the invention, natural latex and styrene-butadiene latex are used as main materials, the latex molecules basically keep an original state, high initial bonding capability of an environment-friendly type high-bonding heat-vulcanization rubber overshoes water-emulsion bonding system can be ensured, rubber polymer is not changed, the vulcanized crosslinked adhesive and a to-be-bound part form a high-tenacity unity, the unity has high final-bonding intensity, the surface viscosity requirement of the to-be-bound part is not high, the temperature requirement of the to-be-bound part is low, and the thermal-insulation performance requirement of the to-be-bound part is reduced. The initial bonding force of the adhesive and the to-be-bound part as well as affinity are increased, plastic flowing of the molecules on a bonding surface of high temperature vulcanized initial rubber part is prevented, and the rubber part and a shoe upper part are firmly bound, so that three quality problems of lace delamination, base fabric disengaging, and large base elastic edge of the rubber overshoes can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of rubber processing, in particular to an environment-friendly heat-vulcanized water-emulsion adhesive for rubber shoes with high adhesive effect and a preparation method thereof. Background technique [0002] The adhesive used in rubber shoes, commonly known as glue, is used to bond the rubber sheet of the rubber shoe skirt and the upper, so that the rubber shoe skirt film and the upper form a firm whole. The main indicators for judging the performance of the adhesive are the bonding strength between the rubber shoe skirt glue and the shoe upper and the peeling failure state during the measurement of the glue strength. Adhesive performance 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 with rubber compound rubber as the solute and organic matter as the solvent. The solvent...
