Manufacturing method
of silicone rubber compound
1. Introduction

silicone rubber compound is an important raw material widely used in the field of chemical production, with excellent high temperature resistance, oxidation resistance, corrosion resistance, electrical insulation and other properties. In order to meet the needs of different application scenarios, it is very important to improve the performance and quality stability of silicone rubber compounds. The purpose of this paper is to explore the manufacturing method of silicone rubber compound, and to provide reference for improving product quality and production efficiency.

2. materials and equipment

1. Materials: silicone rubber raw rubber, filler, vulcanizing agent, catalyst, etc.
2. Equipment: internal mixer, open mill, mixer, extruder, etc.

3. manufacturing methods

1. ingredients: according to product requirements, raw rubber, filler, vulcanizing agent, catalyst, etc. according to a certain proportion of ingredients.
2. Mixing: Put the ingredients into the mixer, and carry out the mixing operation of high temperature, high pressure and high shear force, so that the components are fully mixed and evenly, and the plasticity of the rubber material is improved.
3. Opening: Put the mixed rubber into the opening mill for low temperature and low pressure opening operation to further adjust the plasticity and uniformity of the rubber, and add necessary additives, such as antioxidants, flame retardants, etc.
4. parking: park the rubber material after opening for a certain period of time to make all kinds of additives fully diffuse and improve the stability of the rubber material.
5. Refining: Refining the parked rubber material to improve the uniformity and consistency of the rubber material and prepare for subsequent molding processing.
Precautions for
4.

1. Strictly control the proportion and addition sequence of each component to ensure the stability of the rubber compound performance.
2. In the process of mixing and opening, the process parameters should be adjusted according to the equipment performance and rubber material characteristics to avoid over-refining and under-refining.
3. In the process of parking and remelting, it is necessary to ensure that the ambient temperature, humidity and other conditions are suitable to prevent the rubber from producing early vulcanization or aging.

5. quality inspection and control

1. Real-time monitoring and recording of key parameters in the manufacturing process, such as temperature, pressure, shear force, etc.
2. Quality inspection of the silicone rubber mixture, including physical properties, chemical properties, electrical properties and other aspects of the test to ensure that the product meets the relevant standards and customer requirements.
3. Trace and analyze the unqualified products, find out the cause of the problem and take corresponding measures to improve the product quality and production efficiency.

6. environmental protection and safety requirements

1. In the manufacturing process, environmental protection laws and regulations should be followed to reduce the discharge of waste gas, waste water, waste residue and other pollutants.
2. Regular maintenance and maintenance of production equipment to ensure normal operation of equipment and reduce failure rate and maintenance costs.
3. Strengthen the safety awareness and operation skills training of employees to improve their safety awareness and ability to respond to emergencies.

7. conclusion The manufacturing method of

silicone rubber compound involves multiple links and process parameters, and it is necessary to strictly control the operation and quality inspection of each link to ensure the stability of product performance and quality. At the same time, strengthen environmental protection and safety management, reduce production costs, and improve the competitiveness and sustainable development of enterprises.
