The manufacturing method of chloroprene rubber is a high-performance synthetic rubber with excellent properties such as oil resistance, ozone resistance, chemical corrosion resistance, and heat resistance. Therefore, it is widely used in fields such as chemical industry, automotive, aerospace, and construction. This article will provide a detailed introduction to the manufacturing method of chloroprene rubber

1、 The manufacturing of chloroprene rubber requires the following raw materials: monomers such as chloroprene, styrene, acrylonitrile, as well as initiators, emulsifiers, and other additives. Among them, chloroprene is the main monomer, and the role of styrene and acrylonitrile is to regulate the properties of rubber

2、 Lotion polymerization 

Add the above raw materials into lotion in a certain proportion to carry out lotion polymerization. The specific operation steps include: adding monomer and auxiliary agent into the emulsifier to form a stable lotion system; Then add an initiator to initiate monomer polymerization reaction, generating chloroprene rubber particles

3、 Coagulation and drying 

After the completion of lotion polymerization, coagulation and drying are required to obtain finished neoprene. The specific operation steps include: adding coagulant into the lotion to agglomerate the neoprene particles into blocks; Then dry the block material to obtain the finished chloroprene rubber product

4、 In order to further improve the performance of chloroprene rubber, some post-treatment operations are required. For example, some additives such as anti-aging agents and antioxidants can be added to improve the heat resistance and aging resistance of chloroprene rubber; Sulfurization treatment can also be carried out to improve the mechanical properties and chemical corrosion resistance of chloroprene rubber

In a word, the manufacturing of neoprene requires several steps, including raw material preparation, lotion polymerization, coagulation drying and post-treatment. Each step requires strict control of process parameters and operating conditions to ensure the quality and performance of the final product

In the manufacturing process of chloroprene rubber, the following points need to be noted: first, the quality and proportion of monomers must be strictly controlled to ensure the performance and quality of the final product; Secondly, it is necessary to control the temperature and time of the polymerization reaction to avoid side reactions and affect product quality; Finally, attention should be paid to the storage and transportation conditions of the product to avoid being affected by factors such as moisture, heat, and light

In addition to the precautions mentioned above, the manufacturing of chloroprene rubber also needs to consider environmental protection and sustainable development issues. In the production process, it is necessary to minimize the discharge of wastewater and exhaust gas as much as possible, improve resource utilization and production efficiency. At the same time, it is necessary to actively develop new technologies and processes to further improve the performance and quality of chloroprene rubber and meet the constantly changing market demands

In short, the manufacturing of chloroprene rubber is a complex and meticulous task that requires support from various technologies and knowledge. Only by mastering the correct manufacturing methods and precautions can high-quality and high-performance chloroprene rubber products be produced, making contributions to the development of chemical, automotive, aerospace and other fields.
