The difference between methyl silicone oil and amino silicone oil?
Methyl silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertness and small surface tension. It also has a low viscosity-temperature coefficient and high compression resistance. Generally used as a lubricant, the heat transfer medium amino silicone oil is the basic ingredient specially used for textile softening and finishing agents. It has the best adsorption, compatibility and easy emulsification. Using a mixer or homogenizer, aminosilicone oils are easily emulsified with appropriate surfactants into stable, transparent microemulsions. It can be used alone or combined with other silicone or organic softeners to form a special softening finishing agent, which is suitable for softening finishing of various textiles. It can be used as a structural control agent for silicone rubber and a finishing agent for fabrics, which can significantly improve the smoothness and seam performance of polyester threads, high temperature resistance, and antistatic performance. It has good elasticity, is flat and plump, and can endow the fabric with waterproof and water-repellent properties. The difference in the substituents leads to the difference in their properties.

Block copolymer silicone oil refers to polyether silicone oil, and the silicone oil with polyoxyethylene or polyoxypropylene group, fatty alcohol polyoxyethylene polyoxypropylene ether group connected to the carbon atom of the side chain is polyether silicone oil, which is to improve the first. , The second-generation silicone softener is a product developed by the unsatisfactory shear resistance of silicone emulsion and the poor hygroscopicity of the finished fabric during the use of the second-generation silicone softener.


It can be prepared by addition reaction of hydrogen-containing silicone oil and unsaturated polyether under the catalysis of platinum catalyst, or by the ring-opening reaction of epoxy silicone oil and polyether, or the reaction between alcoholic hydroxyl modified silicone oil and bifunctional carboxylic acid and polyether. prepared by esterification.

After the hydrophilic polyether group is introduced into the side chain, the hydrophilicity of the silicone oil increases, and even completely converts from hydrophobicity to water-solubility. Therefore, the problem of demulsification and oil floating will not occur during the use of polyether modified silicone oil. Secondly, the introduction of polyether group also increases the hygroscopicity, antistatic property and easy decontamination of the finished fiber or fabric, so polyether silicone oil is used more in cosmetics and shampoo products. However, the self-crosslinking film-forming ability of polyether silicone oil and the binding ability with fibers are weak. This problem can be solved if some epoxy groups are introduced or retained on the main chain of the silicone oil during the preparation process. Therefore, in terms of performance, it not only has all the advantages of polyether silicone oil, but also the finished fabric is softer, wrinkle-resistant, washable, and has a strong wool feel.
