Problems solved by technology

[0003] Amino silicone oil is mostly used in the state of emulsion. The high viscosity and low surface tension of amino silicone oil determine that it is difficult to emulsify. The particle size and distribution of the emulsion have a great influence on the use effect of amino silicone oil emulsion. When used in the same state, the moldability, film density, softness and other properties of the fiber are greatly improved, so the microemulsion can effectively improve the performance of amino silicone oil, and the amino silicone oil microemulsion prepared by itself in the Chinese market is more solid The content is low, which brings a lot of inconvenience to storage and transportation. There are already high-solid-content and stable amino silicone oil microemulsions abroad, but imported amino silicone oil microemulsions are often mixed with emulsifiers and other additives, making the cost higher. inconvenient

Embodiment 1

[0025] Add 140g of amino silicone oil with a viscosity of 850mPa·s and an ammonia value of 0.38 into a 250ml beaker, and add an emulsifier compounded with 2-octylphenol polyoxyethylene ether (TX-7 and TX-10). The HLB value of the product is 13.0, and the amount of emulsifier is 29% of the amino silicone oil quality. Stir for 40min with a strong shearing paddle at 400r / min, add a co-emulsifier, and the co-emulsifier includes 10% n-butanol, 1.15% Acetic acid, 15g of water, continue to stir for 40min, add 0.1% KCl (dissolved in 8g of water in advance), add about 10g of water, continue to stir for 40min, a viscous emulsion containing more white bubbles can be obtained, and the bubbles disappear after standing for a period of time. It is transparent. Namely the amino silicone oil microemulsion of the present invention.

[0026] The gravimetric method has a solid content of about 78%, and when diluted with water to a solid content of 10%, a blue-light transparent microemulsion is o...

Embodiment 2

[0029] According to the operation of Example 1, the amino silicone oil was changed to a viscosity of 1000 mPa·s, the compound emulsifier was changed to an HLB value of 12.8, and other conditions were unchanged to prepare an amino silicone oil microemulsion. The solid content is 72±2%, and the particle diameter of the microemulsion measured by a laser particle size analyzer is 64.6nm.

Embodiment 3

[0031] According to the operation of Example 1, the amino silicone oil was changed to a viscosity of 500 mPa·s, the compound emulsifier was changed to an HLB value of 13.1, and other conditions were unchanged to prepare an amino silicone oil microemulsion. The solid content is 76±2%. The particle size of the microemulsion measured by the laser particle size analyzer is 24.6nm

Abstract

The invention discloses a high solid content amido silicon oil microemulsion, which is characterized by the following: allocating with mass percent as 1%-60% amido silicon oil, 5%-19% emulsifying agent, 2. 5%-10% coemulsifier, 0. 01%-0. 1% ionogen and 15%-90% water; adopting antiphase (anti-phase) emulsifying method; mixing the emulsifier and the silicon oil; adding into coemulsifier, water and ionogen; producing bi-continuous phase structural emulsion between O / W and W / O; diluting; changing to amido silicon oil microemulsion of the O / W. This amido silicon oil microemulsion is bi-continuous type structure, which possesses simple course and easy control.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a high-solid-content amino silicone oil microemulsion and a preparation method thereof. Background technique [0002] Amino silicone oil has the characteristics of good adsorption, good molding and orientation, can give fabrics a soft and smooth feel, and greatly improve the softness and smoothness of fabrics. It is the most popular softening agent in the field of textile auxiliaries in recent years. The main chain structure of amino silicone oil is similar to that of methyl silicone oil. The main chain of the molecule is very flexible. It is almost zero, very free, and can rotate 360°. This feature makes silicone oil the best fabric softening agent, and the amino group can interact with the hydroxyl groups and shuttle groups on the fiber surface, and it is very firmly oriented and adsorbed on the fiber. , forming a very firm film on the surface of the fiber, reducing the stat...
