When designing an effective and semi-effective vulcanization system, use a sufficient amount of fatty acids (lauric acid is better than stearic acid) to

Increasing the dissolving ability of zinc oxide in the rubber compound, thereby ensuring that the accelerator fully exerts its active action. In addition, the accelerator should be exhausted

It is possible to use a combination method to increase the vulcanization activity and reduce the total amount of the accelerator. And in the selection of accelerator varieties

It is better to form the AA type and the NA type and use the system to obtain better scorch resistance and vulcanization flatness. Adapt to

The need for a high temperature rapid vulcanization process. In order to ensure the safety of the operation, a scorch retarder should be used if necessary.

Due to certain accelerators such as CZ, TMTD, TETD, etc., the solubility in rubber is not ideal, stearic acid and oxidation

The solubility of zinc stearate formed by zinc reaction in rubber is also low, so in recent years, when diene rubber is vulcanized, it is adopted.

The so-called soluble effective vulcanization system. The sulfur content of the soluble vulcanization system generally does not exceed its solubility in the rubber compound. The accelerator uses TBTD and NOBS, and zinc soap (such as zinc 2-ethylhexanoate) is used instead of zinc oxide and stearic acid. Agent. The advantage of the soluble effective vulcanization system is that the vulcanization degree of the product is uniform, the hardness of the vulcanized rubber is uniform, the stress relaxation and the creep speed are slow, thereby improving the dynamic performance and obtaining high production efficiency.
