Introduction

Silicone oil is a kind of polyorganosiloxane with different degree of polymerization chain structure. It is obtained by hydrolyzing dimethyldichlorosilane with water to obtain an initial polycondensation ring body. The ring body is cracked and rectified to obtain a low Chemicalbook ring body, and then the ring body, capping agent and catalyst are put together. Silicone oil can be obtained from mixtures of various degrees of polymerization and distillation under reduced pressure to remove low boilers.

Chemical properties

Milky white viscous liquid, non-volatile and odorless. Relative density O.98～1.02. It is miscible with chlorinated hydrocarbons such as benzene, gasoline, aliphatic hydrocarbons and aromatic hydrocarbon solvents, insoluble in methanol Chemicalbook, ethanol and water, but can be dispersed in water. Not easy to burn, non-corrosive, chemically stable. ADI0 ~ 1.5mg / from (FAO/WHO, 1994).

Use

●  As an emulsifier, my country stipulates that it can be used in the fermentation process, and the maximum use amount is 0.2g/kg.

●  Used as advanced lubricating oil, anti-vibration oil, insulating oil, defoaming agent, release agent, polishing agent and vacuum diffusion pump oil, etc.

●  It can be used as moisture-proof and anti-rust coating on metal surface, and can also be used as waterproof coating on building surface.

●  Used as a rigid polyurethane foaming aid

Production method

The polymethylsiloxane and fumed silica are mixed with rollers to form silicone grease, and then polyoxyethylene alcohol, Tween 80 and deionized water are added to emulsify.
