With the advancement of technology and the development of the chemical industry, the application of standard adhesive in the field of chemical raw materials is becoming increasingly widespread. Standard adhesive has excellent performance and a wide range of applications, so its manufacturing method has attracted much attention. This article will provide a detailed introduction to the manufacturing methods of standard adhesives, including steps such as raw material preparation, mixing, plasticization, and molding, in order to provide useful references for chemical production

2、 Raw material preparation 

1 Natural rubber: Choose high-quality natural rubber as the main raw material, requiring high rubber content, low impurities, and uniform color

2. Synthetic rubber: According to the performance requirements of the product, suitable synthetic rubber can be selected as auxiliary raw materials, such as styrene butadiene rubber, butadiene rubber, etc

3. Fillers: Commonly used fillers include calcium carbonate, clay, carbon black, etc., used to improve the strength and hardness of rubber materials

4. Additives: such as vulcanizing agents, accelerators, anti-aging agents, plasticizers, etc., used to improve the processing and usage performance of rubber materials

3、 Mixing 

Put the prepared raw materials into the mixer in a certain proportion for mixing. During the mixing process, it is necessary to control the temperature and time to ensure that the raw materials are fully and uniformly mixed. After mixing, take out the rubber material for testing and adjustment to meet the production process requirements

4、 Plasticization refers to the process of plasticizing a mixed rubber material through an extruder or open mill to give it a certain degree of plasticity and fluidity. During the plasticization process, it is necessary to control parameters such as temperature, pressure, and speed to ensure the quality of the rubber material

5、 Forming is the process of processing plasticized rubber into the desired shape and size of a product. The commonly used molding methods include rolling, injection, extrusion, etc. During the molding process, it is necessary to control parameters such as temperature, pressure, and time to ensure the dimensional accuracy and surface quality of the product

6、 Vulcanization refers to the crosslinking reaction of formed rubber materials through vulcanization equipment, which gives them certain properties such as strength, hardness, and wear resistance. During the vulcanization process, it is necessary to control parameters such as temperature, time, and pressure to ensure the degree of vulcanization and product quality

7、 After the vulcanization is completed, a comprehensive quality inspection of the product is required, including inspection of appearance, size, performance, and other aspects. After passing the inspection, packaging is carried out to ensure the quality of the product during transportation and use

8、 Notes 

1 Throughout the manufacturing process, it is necessary to strictly control the temperature, time, pressure and other parameters of each process to ensure product quality

2. The selection and treatment of raw materials should comply with environmental requirements to avoid pollution to the environment

During the production process, regular equipment maintenance and upkeep should be carried out to ensure the normal operation of the equipment and improve production efficiency

9、 Conclusion: The manufacturing method of standard adhesive includes steps such as raw material preparation, mixing, plasticization, molding, vulcanization, quality inspection, and packaging. Throughout the manufacturing process, it is necessary to strictly control the parameters of each process to ensure product quality. At the same time, attention should be paid to environmental protection and equipment maintenance requirements to improve production efficiency and enterprise efficiency.
