Problems solved by technology

[0005] The technical problem to be solved by the present invention is to solve the problem of delamination of the rubber shoe skirt by adjusting the formula of the reinforcing rubber compound, and provide a kind of ultra-low temperature rapid vulcanization reinforcing rubber for rubber shoes and its preparation method. The cross-linking stress increases the speed of cross-linking and setting, ensuring that the cross-linking stress is greater than the sum of "outsole rebound force + expansion force generated by sponge foaming", and makes the reinforcement strips and the outsole straight mouth, surrounding strips, and uppers The glue is cross-linked and shaped before the plastic flow period of the glue, which fundamentally avoids the problem of delamination of the rubber shoe skirt

Abstract

The invention discloses an ultra low temperature fast vulcanization strengthening adhesive used by rubber shoes and a preparation method of the strengthening adhesive, which is characterized in that:firstly, natural rubber is masticated to form masticated rubber, product A is obtained by mixing the masticated rubber and the synthetic rubber, the product B is obtained by mixing the polyethylene glycol and the silica, the product C is obtained by mixing the vulcanizing agent, the vulcanization accelerator and the vulcanization active agent; the product A is put into the rubber refiner to be refined for 0.5 to 1 minute, the product C is added into the rubber refined and keep on refining for 2 to 5 minutes, and then softener is added into the refiner to be refined homogenously, when the discharged material reaches the flattening machine, the supplementary re-processing is carried out to obtain the rubber compound, at last sulfur is added into the rubber compound to obtain the ultra low temperature fast vulcanization strengthening adhesive. The preparation method of the strengthening adhesive has the advantages that: the prescription of the strengthening adhesive materials are improved, the crosslinking stress of the strengthening adhesive is enhanced, thus, the crosslinking stress is ensured to be larger than the rebound force of the outsole plus the expansive force produced by the foaming sponge, and the crosslinking calibration speed is increased; meanwhile, the rubber foxing delamination problem is totally avoided.

Description

Technical field [0001] The invention relates to a reinforcing glue and a preparation method thereof, in particular to an ultra-low temperature fast vulcanizing reinforcing glue which solves the delamination of rubber shoe strips and a preparation method thereof. Background technique [0002] Under normal circumstances, the girdle strip (also known as lace) of rubber shoes is tightly adhered to the upper, that is, the girdle strip and the reinforcing strip, the straight mouth of the outsole and the glue are glued together, and the strip remains the original piece. The thickness is unchanged. However, in the production process of rubber shoes, due to various conditions, it is easy to cause the problem of delamination of the band, that is, the straight opening of the outsole is separated from the reinforcing rubber strip and the glue to form a cavity and the straight opening of the band Thinning and degeneration affects the performance of rubber shoes. [0003] The reason for the de...
