The manufacturing method of butadiene rubber 

1. Introduction 

1. butadiene rubber is an important raw material for chemical production, widely used in rubber products such as tires, tape, and hoses. Its molecular structure is mainly composed of cis-1,4-polybutadiene, which endows cis-1,4-polybutadiene rubber with excellent properties such as elasticity, wear resistance, and crack resistance. This article will provide a detailed introduction to the manufacturing method of butadiene rubber

2、 The manufacturing of butadiene rubber mainly requires the following raw materials: butadiene. In addition, in order to regulate the polymerization reaction, additives such as catalysts and terminators need to be added. The specific formula ratio can be adjusted according to production equipment and process

3、 The manufacturing process of butadiene rubber mainly includes the following steps: Catalyst preparation: Add the catalyst to the solvent in a certain proportion, stir evenly, and prepare a catalyst solution

2. Butadiene polymerization: In a polymerization reactor, butadiene monomers are mixed with a catalyst solution and undergo polymerization reaction at a certain temperature and pressure to generate cis-1,4-polybutadiene

3. Termination reaction: When the polymerization reaction reaches the predetermined conversion rate, a termination agent is added to stop the polymerization reaction

4. Glue treatment: The terminated glue is degassed and dehydrated, and then sent to the post-treatment process

5. Post treatment: After coagulation, drying, pressing and other processes, the finished product of butadiene rubber is obtained

4、 Notes 

1 The selection of catalysts has a significant impact on the performance of butadiene rubber, so it is necessary to choose the appropriate catalyst according to product requirements

2. The temperature, pressure and other parameters of the polymerization reaction need to be strictly controlled to ensure the quality and yield of the product

During the production process, it is necessary to regularly inspect and maintain the equipment to ensure its normal operation

5、 Conclusion: The manufacturing method of polybutadiene rubber involves multiple processes and control of process parameters. Only by mastering these key technologies can high-quality polybutadiene rubber be produced. Through the introduction in this article, we hope to be helpful to readers in the manufacturing process of butadiene rubber.
