Fluorosilicone oil used as a treatment agent

Fluorosilicone oil is often used in waterproof and antifouling finishing of fabrics and leather, and has oil and solvent repellency. Generally speaking, the alkyl chain containing 8-10 perfluorocarbon atoms can achieve the greatest waterproof and oil repellent effect. For fluorine-containing silicone polymers with the same number of carbon atoms, the water and oil repellency of linear chains is more effective than that of branched chains.

1. Fluorosilicone oil containing heptafluoroisopropoxypropyl (or ethyl) side chain, its unique T-shaped fluorine-containing structure endows the product with a good fluorine shielding effect, which can greatly improve the water and oil repellency of the fabric when used in fabric finishing , antifouling performance;

2. Fluorosilicone oil prepared from mercapto silicone oil and fluorine-containing monomers (such as fluoroacrylates) can improve its oil-proof performance after being used in textiles, especially fiber products;

3. The fluorosilicone oil obtained by reacting allyl siloxane and fluorine-containing mercaptan in the presence of AIBN at 100°C-105°C is used for cotton fabric finishing, and the finished fabric still has good dry cleaning and wet cleaning. Waterproof and oil repellent effect;

4. Synthesize fluorosilicon-modified polyurethane waterproof and oil-repellent finishing agent with perfluoroolefin, hydroxy silicone oil, ethylene oxide and diisocyanate as raw materials. It is used for waterproof and oil-proof finishing of fabrics, leather and other fiber fabrics, so that it has excellent Waterproof, oil-proof, and increase softness, smoothness and elasticity;

5. Fluorosilicone oil is obtained by polymerizing macromolecular hydrogen-containing silicone oil and fluorine-containing olefin under the catalyst. The fluorine content in the polymer is controllable, and can be widely used for waterproof and oil-proof treatment of textiles, paper, metal, glass, ceramics and other surfaces. Release agent for plastic and rubber, and drag-reducing treatment agent for water and oil pipelines;

6. Glass wool impregnated with fluorosilicone oil has good waterproof, oil-proof and corrosion-resistant properties. It is used in chlor-alkali industrial mist eliminators. Improve the quality of liquid chlorine and hydrogen chloride;

7. A solvent-based product based on alkenyl-containing fluorosilicone oil, which can be used as a release agent and has good adhesion to various substrates (paper, plastic film);

8. Mix fluorosilicone oil, amino silicone oil, epoxy silicone oil, polyether silicone oil, cationic/nonionic mixed surfactant and deionized water at 56°C-60°C for 3h-5h to make an oil agent for carbon fiber drawing production During the process, the oil agent evenly forms a film on the surface of the monofilament, which can prevent the adhesion and doubling of the monofilaments, and also prevent the friction and wear between the fiber surface and the roller during the production process, with excellent smoothness and antistatic properties , clustering and self-emulsifying properties.
