Introduction to the application scope of amino silicone oil

The amino group in the amino silicone oil molecule has strong polarity, high reactivity, adsorption, compatibility and easy emulsification. It is widely used in fiber finishing agents, resin modifiers, coating additives, brighteners and cosmetic additives.

1. Amino silicone oil is used as a textile fiber finishing agent

The amino group in the amino silicone oil molecule can interact with the hydroxyl group, carboxyl group, etc. on the fiber surface, and form a very strong orientation and adsorption with the fiber, so that the friction coefficient between the fibers decreases and the fiber products are comfortable to wear. Amino silicone oil is the most important softener for natural fibers such as cotton, linen, silk, and wool textiles, and synthetic fibers such as polyester, nylon, and polyacrylonitrile. It is an indispensable raw material for high value-added and high functionality of fiber products.

2. Amino silicone oil can be used as a polymer modifier

Amino silicone oil reacts with the functional groups of organic polymers to introduce siloxane into organic polymers, thereby giving the polymers new properties. For example, amino silicone oil can be used as a monomer for the synthesis of organic polymers or melt-mixed with polymers to modify the resin. There are thermoplastic resins such as polyamide, polyimide, polyurethane, polyester, and thermosetting resins such as epoxy and phenolic. For example, when aromatic tetracarboxylic acid, anhydride, and amino compounds are condensed, modified silicone oil with aminopropyl groups at both ends is added to obtain silicone-modified polyimide. Due to the introduction of siloxane links in its molecules, it has very good adhesion to semiconductor contacts, glass and other substrates, and is widely used as a protective film for semiconductors. Oxycyclic resin plastic encapsulation materials used in integrated circuits often cause cracking of the encapsulation resin, passivation of the silicon wafer surface, cracking of the film, and broken interface due to their internal stress. If silicone oil modified with aminopropyl groups at both ends is added to epoxy resin for comprehensive modification, the softness, toughness and yield rate of the plastic encapsulation material can be improved, and its internal stress can be reduced. When synthesizing polyamide, modified silicone oil with terminal amino groups is added to caprolactam and co-condensed with equal molecular weight adipic acid. The silicone-modified polyamide obtained can significantly improve the low-temperature impact strength without affecting the coating properties of the product.

3. Amino silicone oil as a paint additive

Amino silicone oil as a paint additive can effectively prevent uneven color and wrinkles and increase brightness. The polyurethane coating used for decorative panels has a low coating hardness, is easy to stick to each other when piled together, and is easily damaged when pulled apart. Adding amino silicone oil can make the coating have very good anti-corrosion performance.

4. Amino silicone oil is used as a release agent, cosmetic additive, softener and brightener
