Silicone oil is generally colorless (or light yellow), odorless, non-toxic, and non-volatile liquid. Silicone oil is insoluble in water, methanol, glycol and -ethoxyethanol. It is miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene. It is slightly soluble in acetone, dioxane, ethanol and butanol . It has a small vapor pressure, a higher flash point and ignition point, and a lower freezing point. As the number of segments n is different, the molecular weight increases and the viscosity also increases. The solid silicone oil can have a variety of different viscosities, from 0.65 centistokes to millions of centistokes. If you want to make low-viscosity silicone oil, you can use acid clay as a catalyst and telomerize at a temperature of 180°C, or use sulfuric acid as a catalyst to telomerize at a low temperature to produce high-viscosity silicone oil or viscous. Alkaline catalyst.
Silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertia and small surface tension. In addition, it also has a low viscosity-temperature coefficient, high compression resistance, and some varieties also have radiation resistance. Performance.It is often not used alone, but is made through a special formula, and is often used as an auxiliary material to produce a certain effect. Generally speaking, there are three basic forms of silicone oil on the market: pure silicone oil, solution, and emulsion.
Silicon Oil can be divided into primary commodities and secondary commodities according to its processing conditions. The former refers to silicone oil products before processing, including 4 categories of hydroxy silicone oil, silicone functional silicone oil, carbon functional silicone oil and non-reactive modified silicone oil. Among these 4 categories, it is customarily called
The first two types are linear silicone oils, and the latter two are called modified silicone oils. Secondary silicone oil products refer to greases, emulsions, and creams that are made of silicone oil as a raw material, mixed with thickeners, surfactants, solvents, and additives, and processed by specific technologies.
Products such as solution, such as silicone grease, silicone paste, defoamer, release agent and barrier agent, etc.
Silicone oil has many special properties, such as low temperature viscosity coefficient, high and low temperature resistance, oxidation resistance, high flash point, low volatility, good insulation, low surface tension, non-corrosion to metals, non-toxic, etc. Because of these characteristics, silicone oil has excellent effects in many applications. Among various silicone oils, methyl silicone oil is the most widely used and is the most important variety in silicone oil, followed by methyl phenyl silicone oil. Various functional silicone oils and modified silicone oils are mainly used for special purposes.
Properties: colorless, odorless, non-toxic, non-volatile liquid.
Uses: There are a variety of different viscosities. It has higher heat resistance, water resistance, electrical insulation and lower surface tension. Commonly used as high-grade lubricating oil, anti-vibration oil, insulating oil, defoamer, release agent, polishing agent, release agent and vacuum diffusion pump oil, etc.; emulsion can be used for car tire polishing, dashboard polishing, etc. Methyl silicone oil is the most commonly used. After emulsification or modification, it is used in textile finishing for smooth and soft hand feeling finishing. Emulsified silicone oil is also added to the shampoo of daily care products to improve the lubricity of the hair. In addition, there are ethyl silicone oil, methyl phenyl silicone oil, nitrile silicone oil, polyether modified silicone oil (water-soluble silicone oil) and so on.
Preparation or source: oily substance obtained by hydrolysis and polycondensation of difunctional and monofunctional organosilicon monomers.
Silicone oil has a very wide range of applications. It is not only used as a special material for aviation, cutting-edge technology, and military technology, but also used in various sectors of the national economy. Its application range has been expanded to: construction, electronics, textiles, automobiles, machinery, Leather and papermaking, chemical and light industry, metal and paint, medicine and medical treatment, etc.
The main applications of silicone oil and its derivatives are release agents, shock absorption oils, dielectric oils, hydraulic oils, heat transfer oils, diffusion pump oils, defoamers, lubricants, hydrophobic agents, paint additives, polishing agents, cosmetics and Daily necessities additives, surfactants, particle and fiber treatment agents, silicone grease, flocculants.
Silicone rubber is divided into room temperature vulcanized silicone rubber and high temperature vulcanized silicone rubber. The former is mainly used in sealants, adhesives, conformal coatings, gaskets, foam rubber, molded parts, packaging materials, electrical insulation, glass assembly, medical implants, surgical auxiliary materials, and molding materials; the latter mainly Used in pipes and hoses, strips, wire and cable insulation materials, surgical auxiliary materials, flame-retardant rubber parts, penetrating sealing materials, molded parts, embossing rollers, automotive ignition cables and spark plug covers, extrusion parts, medical Implants, laminates, conductive rubber, fiber coatings, foam rubber.
