The manufacturing method
of cis-polybutadiene rubber
1. Introduction

cis-polybutadiene rubber is an important chemical production raw material, widely used in tires, tape, hose and other rubber products. Its molecular structure is mainly composed of cis -1,4-polybutadiene, which gives excellent elasticity, wear resistance, crack resistance and other properties of cis-polybutadiene rubber. This article will introduce the manufacturing method of butadiene rubber in detail.

2. Raw Materials and Formulations
The manufacture of
butadiene rubber mainly requires the following raw materials: butadiene. In addition, in order to adjust the polymerization reaction, it is necessary to add an auxiliary agent such as a catalyst and a terminator. The specific formula ratio can be adjusted according to the production equipment and process.

3. Manufacturing Process
The manufacturing process of
butadiene rubber mainly includes the following steps:

1. Preparation of catalyst: The catalyst is added to the solvent in a certain proportion and stirred evenly to obtain the catalyst solution.
2. Butadiene polymerization: In the polymerization kettle, the butadiene monomer and the catalyst solution are mixed, and the polymerization reaction is carried out at a certain temperature and pressure to generate cis-1, 4-polybutadiene.
3. Termination of the reaction: When the polymerization reaction reaches a predetermined conversion rate, a terminator is added to stop the polymerization reaction.
4. glue treatment: after the termination of the glue degassing, dehydration treatment, and then sent to the post-treatment process.
5. Post-treatment: After coagulation, drying, briquetting and other processes, the finished cis-polybutadiene rubber is obtained.
Precautions for
4.

1. The choice of catalyst has an important influence on the performance of cis-polybutadiene 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 output of the product.
3. During the production process, the equipment needs to be inspected and maintained regularly to ensure the normal operation of the equipment.

5. conclusion The manufacturing method of

cis-polybutadiene rubber involves the control of many links and process parameters. Only by mastering these key technologies can high-quality cis-polybutadiene rubber be produced. Through the introduction of this article, I hope to help readers in the manufacturing process of butadiene rubber.
