Problems solved by technology

However, since the alcohol-based substance can promote the S-crosslinked rubber molecules at a lower temperature to cause scorching, the safety and stability of the rubber material is poor, and it also seriously affects the production organization.
[0004] The structure of the rubber shoes vulcanization steam tank in the industry adopts a one-way air supply flow design, and the heat circulation air supply adopts a low-speed fan, which leads to low heat supply efficiency inside the steam tank, uneven internal temperature of the vulcanization tank, and large temperature differences at various points, with a range of 15. ℃ above
As the rubber shoes used in the general wearing environment, the rubber vulcanization accelerator is mainly used in the M / DM / D combination system, but the production efficiency is not high because the relationship between the vulcanization speed and the scorch safety performance cannot be coordinated.

Abstract

The invention discloses a vulcanized rubber for shoes capable of realizing high effective and fast vulcanization and a preparation method and a vulcanization process thereof. The vulcanized rubber isprepared from natural rubber, styrene-butadiene rubber, butadiene rubber, accelerator B, accelerator BM, accelerator DS, nanometer zinc oxide, rubber softening oil, sulphur, stearic acid, aging resister CD, carbon black N330, pine tar oil, solid coumarone, reclaimed rubber and pot clay. Compared with the prior art, the vulcanized rubber of the invention has suitable starting time of vulcanization,faster velocity of vulcanization and higher thermal oxidative aging property, the vulcanization efficiency is increased, and the heat-conducting property, processing safety and storage property of the rubber are increased in the vulcanization process; the provided vulcanization process can effectively shorten the vulcanization time, improve the vulcanization quality and increase the vulcanizationefficiency to 2-3 times of the original one.

Description

technical field [0001] The invention relates to the technical field of vulcanized rubber, in particular to a vulcanized rubber for shoes that can be vulcanized efficiently and quickly, a preparation method and a vulcanization process thereof. Background technique [0002] The steam tank is the equipment that must be used in the production of rubber shoes with thermal vulcanization method. In the vulcanization process of rubber shoes with thermal vulcanization method, hot air is used as the vulcanization medium at first. The hot air can oxidize the surface of rubber products, causing the rubber to age and degrade. Stickiness, reducing the performance of the rubber compound, and due to the low thermal efficiency of the air, the vulcanization time of the product is longer. If thiuram accelerators such as accelerator TT are used in combination with thiazole accelerators in the rubber formula to form an AA type accelerator combination system, although the vulcanization time will ...
