What is the purpose of using anti-coke agent for silicone rubber products?

2024-09-30

In the rubber industry, with the development of production and the improvement of the performance of rubber products, the problem of increasing heat generation in the process of rubber processing has appeared. Therefore, how to ensure the safety in the process of processing has become an important topic. Now the main method is to add a small amount of anti-coke agent in the process to improve the safety of the processing process, increase the storage life of the rubber or glue, when adjusting the vulcanization system is difficult to achieve the required operation safety, adding anti-coke agent can often easily meet the requirements of the scorch performance of the rubber. In the process of storage and processing, due to the effect of heat, early vulcanization (cross-linking) will occur and lose the fluidity and reprocessing ability, which is the scorch phenomenon. The burning of rubber is one of the common problems in the process of rubber processing. The burning problem is more likely to occur in the modern characteristics of high temperature, fast and efficient processing technology and the mixing agent that is easy to cause burning (such as reinforcing resin, intermethyl white system adhesive, fine particle carbon black, etc.). Coke burning can be solved by adjusting the vulcanization system, but be careful to change the properties of the compound; The storage or processing conditions of the adhesive can be improved by cooling, but complex equipment is needed, and the use of anti-coke agent is a simple and easy way to prevent scorch. Therefore, the anti-coke agent has become an important operating assistant for the safety of rubber processing.
