Most of the reinforcing agents are used to improve or meet the performance requirements, such as carbon black and white carbon black; while the fillers are mainly to reduce the cost of rubber materials; It is obtained through fine craftsmanship, while the filler is directly obtained from natural minerals, which are generally obtained through relatively simple and rough mechanical processing (mainly crushing and mechanical grinding). Due to the different use effects of the two types of materials, the costs and costs paid are also very different. However, there are similarities between the two types. Therefore, for a long time, people have sought to take both mechanical processing and chemical modification into consideration, that is, using fillers as raw materials, performing fine mechanical processing and surface chemical treatment, to obtain performance and use. Materials whose effects are close to those of reinforcing agents, but whose cost is between the two, are customarily referred to as "reinforcing fillers". In recent years, with the development of various rubber products, the varieties and dosages of modified and improved reinforcing fillers are increasing day by day, becoming a new category in rubber compounding agents.

Therefore, the promotion and application of reinforcing fillers is of great significance, which can be briefly summarized as follows:

1. It helps to reduce the consumption of petroleum energy. The most widely used reinforcing material in rubber is carbon black, and the manufacture of carbon black is inseparable from the supply of petroleum cracking oil, natural gas and other energy sources. Partial replacement of carbon black by strong fillers is equivalent to saving a considerable amount of non-renewable petroleum resources.

2. After the reinforcing filler is used in low-grade products, some key properties are improved and improved, which can play the role of "product upgrade and make the best use of everything."

3. Compared with the production of carbon black, white carbon black and other traditional reinforcing agents, the energy consumption can be greatly reduced.

4. In line with the general development direction of social production such as "protecting the ecological economy", and contributing to the realization of the low carbonization of the rubber industry.
