Silicone emulsion (silicon emulsion for short) is an oil-in-water emulsion composed of silicone oil, water and surfactants.

Silicone emulsion is mainly used as a silicone fabric softening agent. The first generation of silicone fabric finishes were mechanical mixtures of dimethicone and hydrosilicone (and their derivatives). The second generation of silicone fabric finishing agent is hydroxyl-terminated polydimethylsiloxane emulsion, which is emulsified from octamethylcyclotetrasiloxane monomer, water, emulsifier, catalyst and other raw materials under certain conditions. aggregated. Since polymerization and emulsification are completed in one step, it has the advantages of short working hours, high work efficiency, simple equipment, and easy operation. The obtained emulsion is very stable, the particles are very uniform, and the obtained polymer has active groups (hydroxyl groups) at both ends. ) can further react to form a film, which is beneficial to improving the application effect of the emulsion, which is beyond the reach of mechanical emulsified silicone oil.

The role of silicone oil emulsion
Silicone oil emulsion is a commonly used chemical product with a variety of functions and applications. The following are the main functions of silicone oil emulsion:
1. Lubricant: Silicone oil emulsion can form a lubricating film on the friction surface, reducing friction and wear, and improving the working efficiency and life of mechanical equipment.
2. Anti-adhesion agent: Silicone oil emulsion can reduce the adhesion of the material surface, prevent materials, particles or adhesives from adhering to equipment or tools, and facilitate subsequent processing.
3. Preservative: Silicone oil emulsion can form a protective film to prevent oxidation and corrosion of metal surfaces, extending the service life of equipment and parts.
4. Insulating agent: Silicone oil emulsion has good insulating properties and can be used in electronic equipment, wires and cables, and insulating materials to prevent current leakage and failure.
5. Skin care products: Silicone oil emulsion is widely used in skin care products. It can form a protective film to keep the skin moist and smooth, and prevent water evaporation and external stimulation.
6. Surface treatment agent: Silicone oil emulsion can be used for surface treatment to provide a smooth and bright appearance and increase the gloss and visual effect of the material.
