In actual production, it has been proven that the increase in the usage of many alkaline fillers and additives, such as diethylene glycol and carbon black, will also reduce the critical activation temperature of the accelerator and reduce the scorch resistance of the rubber compound.
Adding thiazole and hypoxanthamide accelerators to the formula has excellent scorch resistance. The advantage is that it does not affect the structure and performance of the vulcanized rubber and does not affect the vulcanization speed and induction period. The amount can be adjusted. The anti-scorch effect is an elimination reaction, which increases or prolongs the existence time of the accelerator and reduces the number of complexes formed, which prolongs the induction period. It is currently the best anti-scorch agent. In the formula containing thiazole and hypoxanthamide accelerators, adding a small amount of anti-scorch agent will have great effect on the anti-scorch performance of vulcanized rubber. However, if accelerators such as thiurams and dithiocarbamates are used together in the formula, complexes can still be formed at higher mixing temperatures, and the impact on the anti-scorch performance of the rubber will not be too great. So superior.
Judging from the above numerous tests and practical production situations, the anti-burning ability of the rubber material is mainly determined by the amount of strong active agent complexes generated during the operation of the rubber material. The smaller the amount, the smaller the amount. The lower the activation energy at normal temperature, the longer the consumption time of the scorched part, and vice versa.
Secondly, it depends on the scorch induction period of the accelerator and the formula. The longer the induction period, the better the anti-scorch performance. However, if the operating temperature is too high (such as the internal mixing temperature is too high), more will be generated during the production operation. If the strong active agent complex is used, even if the scorch is very long, it will be exhausted quickly, and the anti-scorch performance of the rubber will be seriously reduced. Generally speaking, the longer the induction period of an accelerator, its critical The higher the activation temperature.
rSilicone adhesive sharing: Lowering the tableting temperature, using pre-dispersed masterbatch, shortening the tableting time, and using insoluble sulfur are the most effective methods. In the tire industry, in order to prevent scorch, insoluble sulfur and Anti-scorch agent has been widely used.
Slowing down the vulcanization speed is also a commonly used method. Although it can solve the problem, the stability of the rubber compound is far less than that of controlling the activation energy of the accelerator.
When the equipment and process cannot be changed, the most effective method is to use insoluble sulfur or use insoluble sulfur in combination. It can effectively solve the problem of early vulcanization of rubber materials, which will be of great significance to the stability of the production process and the assurance of product quality. It has been proven effective through large-scale production promotion.
