The manufacturing method of fluororubber 

1. Introduction 

Fluororubber is a special rubber with excellent oil resistance, high temperature resistance, chemical corrosion resistance and other characteristics, widely used in aviation, aerospace, automotive, petrochemical and other fields. This article will provide a detailed introduction to the manufacturing method of fluororubber, including process steps such as raw material preparation, mixing, and vulcanization

2、 Raw material preparation 

1 Fluorine rubber raw rubber: Choose fluorine rubber raw rubber with high fluorine content to ensure the performance of fluorine rubber

2. Sulfurizing agents: Commonly used vulcanizing agents include bisphenol AF, bisphenol S, etc

3. Promoter: A substance that promotes vulcanization reactions, such as dimethylaniline

4. Filler: Improve the physical properties of fluororubber, such as carbon black, white carbon black, etc

5. Antioxidants: Improve the heat and oxygen aging properties of fluororubber, such as phenylbenzimidazole

3、 Mixing process 

1 Add raw materials such as fluororubber rubber, vulcanizing agent, accelerator, filler, anti-aging agent, etc. to the mixer in a certain proportion

2. Mix at a certain temperature to ensure that the raw materials are thoroughly and evenly mixed

During the mixing process, attention should be paid to controlling temperature and time to avoid overheating or over mixing of the rubber material

4. After the mixing is completed, place the rubber material on an open rubber mixing machine for thinning and further homogenizing the rubber material

4、 Sulfurization process 

1 Cut the mixed fluororubber material into a certain shape and size of film

2. Put the film into the mold and vulcanize it at a certain temperature and pressure

During the vulcanization process, attention should be paid to controlling temperature, pressure, and time to ensure the degree of vulcanization and physical properties of fluororubber

4. After vulcanization, take out the vulcanized fluororubber product and perform post-treatment, such as removing burrs, cleaning, etc

5、 Notes 

1 In the manufacturing process, it is necessary to ensure the control accuracy of temperature, time, pressure and other parameters in each process step to ensure the stable quality of fluororubber

2. During the manufacturing process, attention should be paid to safety to avoid safety accidents caused by improper operation

When using raw materials, it is necessary to ensure the quality of the materials and avoid affecting the performance of fluororubber due to raw material issues

6、 Summary: The manufacturing method of fluororubber includes steps such as raw material preparation, mixing process, and vulcanization process. The control of temperature, time, pressure and other parameters in each process step is crucial to ensure the stable quality of fluororubber. At the same time, attention should be paid to safety and environmental protection during the manufacturing process, to avoid safety accidents and environmental pollution caused by improper operation. By using the manufacturing method introduced in this article, fluorine rubber with excellent performance can be prepared, providing important material support for the raw material field of chemical production.
