Purpose of using anti-scorching agents

In the rubber industry, with the development of production and the improvement of the performance of rubber products, the problem of increasing heat generation during the processing of rubber has arisen one after another. Therefore, how to ensure the safety of processing has become an important issue. The main method used now is to add a small amount of anti-scorching agent in the process, to improve the safety of the process, increase the storage life of the rubber or rubber paste, when adjusting the vulcanization system is difficult to achieve the required operational safety, adding anti-scorching agent can often be very simple to meet the requirements of the rubber scorching performance. Rubber in the storage and processing due to the role of heat will occur early vulcanization (crosslinking) and the loss of mobility and reprocessing capacity, which is the phenomenon of scorching. Scorching of rubber is one of the common problems in rubber processing, in the modern characteristics of high temperature, fast, efficient processing and the use of easy to cause scorching agents (such as reinforcing resins, meso-alpha-white system of adhesives, fine particles of carbon black and so on), scorching problems are more likely to occur. Scorch can be solved by adjusting the vulcanization system, but be careful to cause changes in the properties of the rubber; can be cooled to improve the rubber storage or processing conditions, but requires complex equipment, with anti-scorch agent
Is a simple and easy way to prevent scorching. Therefore, the anti-scorching agent has become an important operation auxiliary for the safety of rubber processing.
