Block amino silicone oil, as a high-performance organic silicon material, has a wide range of applications in various fields such as textiles, leather, coatings, and rubber. With the continuous development of the global economy and the increasing demand for high-performance materials in various industries, the market prospects for block amino silicone oil are broad.


Block amino silicone oil is a special type of organic silicon polymer composed of alternating hydrophobic and hydrophilic amino silicone segments. It has the following characteristics and advantages:
Structural characteristics
In the molecular structure of block amino silicone oil, amino functional groups are distributed in the block structure, forming alternating hydrophobic and hydrophilic segments. This structure achieves a balance between hydrophilicity and hydrophobicity.

Performance advantages
Hydrophilicity and Softness: It has instant hydrophilicity, can quickly interact with water, enhance the hydrophilicity of the fabric, and give the fabric a soft and smooth feel.
Washability and stability: During the high-temperature baking process, the amino groups of block amino silicone oil can crosslink with other substances, forming a stable network structure and enhancing its adhesion to fibers, thereby improving washability.
Environmental friendliness: It does not contain irritating volatile solvents and is environmentally friendly.
Color fastness: Will not cause yellowing of the fabric after use, maintaining the original color of the fabric.
Defect free appearance: No oil stains or silicon dots, no sticking to rollers, ensuring a clean and flawless fabric surface.
Chemical and temperature resistance: It has good acid and alkali resistance and high temperature resistance.
High shear resistance: maintains stability during mechanical processing and is not easily damaged by shear.

application area 
Block amino silicone oil is widely used in the textile industry to treat fabric fibers such as cotton, wool, linen, and silk, making the fabric feel soft, smooth, and elastic. In addition, it is also suitable for multiple industrial fields such as cosmetics, pharmaceuticals, lubricants, coatings, etc.

Preparation Method
The preparation method of block amino silicone oil mainly includes:
Silicon hydrogenation and amination reaction method: The method involves the silicon hydrogenation reaction between hydrogen containing silicone oil and terminal vinyl compounds, followed by amination reaction.
Lotion polymerization: octamethylcyclotetrasiloxane (D4), polyether silane and amino silane monomer are used for lotion polymerization in aqueous solution containing emulsifier and catalyst.
Condensation reaction or addition reaction method: such as nucleophilic addition and hydrogen reduction reaction of polyether silicone oil and acrylonitrile.

Difference from ordinary amino silicone oil
Structural difference: The amino functional group of ordinary amino silicone oil is located on the side chain of the polymer, while the amino group of block amino silicone oil is distributed in the block structure.
Performance difference: Block amino silicone oil provides a balance between hydrophilicity and hydrophobicity, while ordinary amino silicone oil has higher hydrophilicity.
Application differences: Block amino silicone oil has a wide range of applications in emulsifiers, defoamers, and stabilizers due to its amphiphilic properties.

In summary, block amino silicone oil has gradually become an important product in the field of organic silicon materials due to its excellent performance and wide application prospects
