Amino silicone oil has a wide range of applications in the fields of fiber finishing, resin modification, cosmetics and coatings. The amino group in amino silicone oil has strong polarity, high reactivity, adsorption, compatibility, and easy emulsification. Fiber finishing agent for textile industry. In addition, it can also be used as paint additives and cosmetic additives.
Amino silicone oil has four important parameters: ammonia value, viscosity, reactivity and particle size. These four parameters basically reflect the quality of amino silicone oil, and will greatly affect the style of the treated fabric. Such as hand feel, whiteness, shade and ease of silicone oil emulsification.
The general application field of amino silicone oil lies in the following points:
Amino silicone oil, as an additive for coatings, can effectively prevent uneven color and wrinkling, and increase the brightness. Polyurethane coatings for decorative panels have low film hardness and are easy to stick to each other when they are piled up. When they are pulled apart, they are easily damaged by wax coating. Adding amino silicone oil can make the coating film have very good anti-adhesion.
2. Brightener
Amino silicone oil is added to polishes for automotive wax, synthetic wood, furniture, leather, etc. to improve durability.
3. Cosmetic additives
Amino silicone oil is an important additive in cosmetics and is mainly used in hair cosmetics such as shampoo, perm, hair repair agent, and hair fixer. The addition of amino silicone oil to the shampoo can make the ingredients such as water and surfactants easier to disperse, and can give the hair soft touch, easy combing and luster.
4. Release agent
The salt composed of amino silicone oil and higher fatty acid is used as an internal mold release agent for plastics and can be used for reaction injection molding of rigid polyurethane foam products with skin layers.
5. Textile softener
At present, amino silicone oil is mainly used in textile softening and finishing agents. In general, according to conventional requirements, the selection of amino silicone oil for different fabrics is:
① Pure cotton and blended knitted fabrics and woven fabrics are mainly soft to the touch, and amino silicone oil with an ammonia value of 0.6 can be selected;
②Pure polyester fabrics are mainly made of smooth hand feel, and amino silicone oil with an ammonia value of 0.3 can be selected;
③Silk knitted fabrics and woven fabrics are mainly made of smooth hand and have high requirements for gloss. The amino silicone oil with ammonia value of 0.3 is mainly selected, and the smoothing agent is compounded to increase the gloss;
④Wool and its blended fabrics are required to be soft, smooth and elastic with a comprehensive hand feel and small changes in color and light. Amino silicone oil compound products with 0.6 ammonia value and 0.3 ammonia value can be selected, and some varieties can be compounded with a smoothing agent to increase elasticity and gloss;
⑤ Cashmere sweaters and cashmere fabrics have a higher overall feel than wool fabrics, and high-concentration compound products can be selected;
⑥ Nylon socks, mainly for smooth hand feel, choose high elastic amino silicone oil;
⑦Acrylic Raschel blankets, acrylic and blended wool are mainly soft and have high requirements for elasticity. Amino silicone oil with an ammonia value of 0.6 can be selected, taking into account the elasticity requirements;
⑧ Hemp fabrics (linen, ramie) are mainly smooth, and amino silicone oil with an ammonia value of 0.3 is mainly selected;
⑨ Rayon and rayon are mainly soft to the touch, and amino silicone oil with an ammonia value of 0.6 can be selected;
⑩Polyester alkali-reducing fabric, mainly to improve the hydrophilicity of the fabric, polyether-modified silicone oil (CGF) can be selected, which is composed of methyl hydrogen-containing silicone oil and polyethylene glycol, polypropylene glycol and other polymers with unsaturated bonds at the end. Ether is made by hydrosilylation reaction. However, the softness is poor. The new polyether modified silicone oil introduces reactive epoxy groups on the silicone chain, which improves the hand feel and durability of the fabric.
