Fluorine rubber, as a kind of special synthetic rubber with high performance, is widely used in many fields because of its excellent high temperature resistance, corrosion resistance and oil resistance. In order to better understand and utilize the properties of fluorine rubber, it is essential to conduct in-depth analysis of its composition. In this paper, the composition of fluorine rubber will be analyzed in detail.
First, the main ingredients
1. The main structure of fluorine rubber is composed of carbon atoms and fluorine atoms alternating arrangement, this special structure makes it have excellent chemical corrosion resistance.
2. Fluorine rubber also contains a small amount of other elements, such as hydrogen, oxygen, sulfur, etc., the addition of these elements helps to improve the processing properties and mechanical properties of rubber.
Second, vulcanization system
1. The vulcanization process of fluorine rubber is achieved by the action of vulcanizing agents, and commonly used vulcanizing agents include sulfur-containing compounds and peroxide.
2. In order to improve the high temperature resistance of fluorine rubber, sulfur-free vulcanizing agents, such as amines and metal oxides, are usually used.
Third, filling system
1. In order to improve the mechanical properties and processing properties of fluorine rubber, fillers are often added, such as carbon black and white carbon black.
2. White carbon black has a porous structure, which can improve the oil resistance and chemical corrosion resistance of fluorine rubber.
Fourth, plasticizer and softener
1. Plasticizers can reduce the viscosity of fluorine rubber and improve its processing performance. Commonly used plasticizers include petroleum plasticizers and ester plasticizers.
2. Softeners can improve the flexibility and cold resistance of fluorine rubber. Commonly used softeners include petroleum softeners and fat oil softeners.
Fifth. Summary
Through the analysis of the composition of fluorine rubber, we can better understand the relationship between its chemical structure and physical properties. In practical applications, according to different use environment and performance requirements, the selection of the appropriate formula and processing technology can give full play to the advantages of fluoroprene rubber and provide strong support for the sustainable development of various industries. At the same time, with the continuous emergence of new fluororubber materials, our understanding of its composition and properties will continue to deepen, providing more possibilities for future research and application.
