Silicone rubber, a vital high-polymer material, requires intricate and precise preparation techniques involving various chemical reactions and process controls. Common methods include thermal vulcanization, cold vulcanization, and liquid silicone rubber processing.

Preparation Techniques:

Thermal Vulcanization: Crosslinking linear polyorganosiloxanes into three-dimensional networks through high-temperature vulcanization, yielding silicone rubber with exceptional heat resistance and mechanical strength.
Cold Vulcanization: Vulcanization at lower temperatures suitable for temperature-sensitive applications. While simplifying the process, it may slightly compromise certain properties.
Liquid Silicone Rubber: Injection molding and other techniques utilize liquid silicone rubber raw materials to produce complex shapes with high production efficiency and flexibility.
Future Prospects:

High-Performance: Introducing novel fillers and modifiers to enhance heat resistance, aging resistance, and mechanical properties.
Environmental Friendliness: Developing low-VOC emission processes to minimize environmental impact.
Multifunctionality: Integrating conductive, thermal, and electromagnetic shielding functionalities to create multifunctional silicone rubber composites.
With advancements in materials science, silicone rubber preparation techniques will mature and expand its application domains, further benefiting human life and industrial development.
