The preparation process of silicone rubber usually includes steps such as selecting raw materials, adding additives, mixing, molding, and vulcanization. The selection of raw materials and the addition of additives have a crucial impact on the performance of silicone rubber.

In terms of raw material selection, high-purity siloxane is usually selected as the basic raw material to ensure the purity and stability of silicone rubber. The addition of additives is selected based on the required properties of silicone rubber. For example, adding fillers can improve the mechanical properties and wear resistance of silicone rubber, while adding vulcanizing agents can promote the vulcanization reaction of silicone rubber.

During the preparation process, mixing is a crucial step that determines the uniformity and quality of silicone rubber. According to specific requirements, different molding methods can be selected for molding, such as rolling molding, extrusion molding, and injection molding. Finally, through the vulcanization process, the silicone rubber obtains the required cross-linking structure and properties.

With the continuous progress of technology, the preparation process of silicone rubber is also constantly developing. The emergence of new catalysts and additives has further improved the performance of silicone rubber. At the same time, the requirements for environmental protection and sustainability are also driving the green development of silicone rubber preparation processes.

In the future, the preparation process of silicone rubber will be more efficient, environmentally friendly, and intelligent. With the continuous emergence of new materials, the performance and application fields of silicone rubber will also be further expanded.
