110 Manufacturing method
of silicone rubber
1. Introduction

With the continuous development of science and technology, silicone rubber has been widely used in many fields, especially in the field of chemical production raw materials. As a common type of silicone rubber, 110 silicone rubber has high heat resistance, cold resistance, oxidation resistance, corrosion resistance and electrical insulation, so it is widely used in electronics, electrical appliances, automobiles, aviation, aerospace and other fields. This article will introduce the manufacturing method of 110 silicone rubber in detail.

2. materials and equipment

1. materials: methyl vinyl silicone rubber rubber, white carbon black, silicone oil, catalyst (platinum complex), inhibitor.
2. Equipment: internal mixer, open mill, extruder, vulcanizing tank, electronic balance, thermometer, pressure gauge.

3. manufacturing steps

1. ingredients: according to a certain proportion of methyl vinyl silicone rubber raw rubber, white carbon black, silicone oil into the mixer, mixing. In the mixing process, the temperature and time should be controlled to ensure the uniform mixing of the rubber material.
2. Parking: The mixed compound is parked at room temperature for a certain period of time to make the compound fully mature.
3. Add catalyst and inhibitor: add the catalyst and inhibitor to the compound according to a certain proportion, and then put it into the internal mixer for mixing to ensure that the additive is evenly dispersed in the compound.
4. Slice: Place the mixed compound on the mill, adjust the temperature and time, so that the compound is smooth and free of bubbles.
5. Vulcanization: The rubber material after the film is put into a vulcanization tank and vulcanized at a certain temperature and pressure. During the vulcanization process, it is necessary to pay close attention to the changes of temperature and pressure to ensure the vulcanization effect.
6. post-treatment: after the completion of vulcanization, take out the silicone rubber products, cleaning, drying and other post-treatment process.

4. Precautions

1. In the manufacturing process, it is necessary to strictly control the temperature, time, pressure and other parameters of each process to ensure the quality of silicone rubber products.
2. to prevent the mixing of impurities, so as not to affect the performance of silicone rubber.
3. The amount of catalyst and inhibitor should be adjusted according to the actual situation to ensure the vulcanization speed and performance of silicone rubber.

5. quality inspection
After the
is manufactured, the quality inspection of silicone rubber products is required, including appearance, hardness, tensile strength, tear strength, elongation, heat resistance, cold resistance, oxidation resistance, corrosion resistance and other performance indicators. Ensure product quality meets relevant standards and customer requirements.

6. environmental protection and safety

in the manufacturing process, need to pay attention to environmental protection and safety issues. Try to choose environmentally friendly raw materials and additives to reduce the emission of waste gas, waste water, waste residue and other pollutants in the production process. At the same time, strengthen the safety management of the production site to prevent accidents.

7. Conclusion

Through the above steps, we can successfully manufacture 110 silicone rubber. In the manufacturing process, it is necessary to strictly control the process parameters to ensure product quality. At the same time, pay attention to environmental protection and safety issues, and promote green and safe production.
