Embodiment Construction

[0019] The gist of the present invention is to prepare the fluorosilicone oil of the present invention, which has an oxygen ether and a silicon bond, its fluorocarbon chain is a branched 9 carbons, and its silicon part is a hydroxyl-containing organosilicon oligomer. The fluorosilicone oil prepared by introducing long-chain fluorocarbon group polysiloxane molecular structure combines the dual properties of organic silicon and fluorocarbons, which not only maintains the inherent excellent high and low temperature resistance, viscosity and temperature properties of silicone oil, but also It can make fluorosilicone oil have three-proof properties. The present invention will be further described below in conjunction with specific embodiment, but specific embodiment does not limit the present invention in any way

[0020] Put 80 kg of organosilicon hydroxy silicone oil, 15 kg of solvent, 20 kg of fluorine monomer, and 1 kg of catalyst into the reaction kettle, and react with alkali...

Abstract

The invention discloses fluorosilicone oil and preparation method of the fluorosilicone oil. The fluorosilicone oil has ether and silicon bonds, its fluorocarbon chain is C9 branched chain or C6 straight chain, and the silicone part is hydroxy-containing organic silicon oligomer. The method is simple, environmentally friendly, and easy to realize. The fluorosilicone oil prepared by introducing long-chain fluorohydroxy to silicone molecular structure combines the properties of silicone and fluorocarbon, not only maintains the inherent excellent high and low temperature resistance and viscosity-temperature property of silicone oil, but also improves waterproof performance, oil resistance and solvent resistance, and is endowed with special properties.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a fluorosilicone oil and a preparation method thereof. Background technique [0002] Among synthetic lubricating oils, methyl silicone oil has excellent high and low temperature performance, but its poor lubricity affects its application. By introducing fluorine elements, its lubricity, low surface energy, excellent solvent resistance, thermal stability, weather resistance and wear resistance can be improved. It has a wide range of applications in the fields of textiles, leather finishing, floor sanding, coatings and coating additives, defoamers, aviation hydraulic fluids, etc. At present, there are many kinds of fluorosilicone oil, and there are several kinds of fluorosilicone oil products of different brands at home and abroad. Their composition is nothing more than the hydrolysis and condensation reaction of trifluoropropyl dichlorosilane. The method is to crack D3F and hyd...
