Fluorosilicone oil has trifluoropropyl groups introduced into the silicon atoms. In addition to the basic characteristics of methyl silicone oil, it also has excellent oil resistance, solvent resistance, and chemical stability. It has good lubricity under extreme pressure conditions and can be used as a lubrication agent. Agents, defoaming agents, surface treatment agents, release agents and additives are widely used in cosmetics, petroleum, leather, paper and pharmaceutical fields. In open systems, it can be used in the temperature range of -40-240℃.
Application in lubricants
Fluorosilicone oil can form a molecular assembly film with an outer chemical composition of -CF3 and high hydrophobic and oleophobic properties through chemical adsorption on the surface of the substrate, which can greatly reduce the friction coefficient of the substrate and make it have good wear resistance under low load. sex.
When trifluoropropyl silicone oil is used as a grease base oil, it can significantly improve the lubricity between steel and steel boundaries; for the watch industry and micromachining industry, since the surface energy of such compounds can be as low as 20mN/m, it can Reduces the surface friction coefficient and can also be used as an advanced lubricant. Lubricants formulated from fluorosilicone oil, perfluoropolyether, polyphenylene ether, etc. are used for the lubrication of record drives, laser printers and other electronic machinery. They can continuously withstand high temperatures above 121°C and operate at high rotational speeds of 1.4 million per minute. Does not decompose and ensures reliable performance of lubricated objects. Typical applications: 1. Vacuum pump lubricant used to handle chemical reaction gases; 2. Can be used for lubrication of bearings in extremely low and high temperature environments; 3. Chemically inert to fuels and other chemicals, used in steam power cycle systems ; 4. Base oil for thickening grease; 5. Grease base oil for watch industry and micro-machinery industry.
Application in surface treatment agents
Fluorosilicone oil is often used for waterproofing and anti-fouling finishing of fabrics, leather, etc. and is oil-repellent and solvent-repellent. Generally speaking, an alkyl chain containing 8-10 perfluorocarbon atoms can achieve the greatest waterproof and oil-repellent effect. For fluorosilicone polymers with the same number of carbon atoms, the water and oil repellency of linear chains is more effective than that of branched chains.
Fluorosilicone oil is obtained by polymerizing macromolecular hydrogen-containing silicone oil and fluorine-containing olefins under a catalyst. The fluorine content in the polymer can be controlled. It can be widely used for waterproof and oil-proof treatment on the surfaces of textiles, paper, metal, glass, ceramics, etc., as well as for plastics, Rubber release agent and drag reducing agent for water and oil pipelines;
Glass wool impregnated with fluorosilicone oil has excellent waterproof, oil-proof and corrosion resistance properties. It is used in chlor-alkali industrial demisters. It has significant dehydration efficiency, reduces equipment corrosion, and significantly extends the service life of the demister. Improved the quality of liquid chlorine and hydrogen chloride;
A solvent-based product formulated with alkenyl-containing fluorosilicone oil as the base polymer, it can be used as a release agent and has good adhesion to various substrates (paper, plastic films);
Mix fluorosilicone oil, amino silicone oil, epoxy silicone oil, polyether silicone oil, cationic/nonionic mixed surfactant and deionized water at 56℃-60℃ for 3h-5h to make an oil agent, which is used in the carbon fiber drawing production process. , the oil evenly forms a film on the surface of the monofilament, which can not only prevent the adhesion and doubling of the monofilaments, but also prevent the friction and wear between the fiber surface and the roller during the production process, and has excellent smoothness, antistatic properties, and bundling properties and self-emulsifying properties.
Application in defoaming agents
Since the surface tension of fluorocarbon-based silicone oil, especially long-chain perfluoroalkyl silicone oil, is lower than that of other silicone oils, the defoaming agent formulated with it is more effective in reducing the surface tension of various foaming systems and is better than other silicone oil defoaming agents. Foaming agent. Both homopolymer and copolymer fluorocarbon-based silicone oils can be used as defoaming agents. Fluorosilicone oil defoaming agents can be used in petroleum, textile, synthetic rubber and resin industries, coating and ink industries, food processing and fermentation industries, and medical applications.
Application in release agents
Fluorosilicone oil can also be used to prepare release agents. It has good anti-stickiness and lubricity, does not corrode molds, is non-toxic and safe, and can be used in processes such as molding, pouring, packaging and coating. Emulsion or solvent-free products formulated with fluorosilicone oil as the base polymer can be used as paper release agents and have very unique properties.
