Embodiment 1

[0024]

[0025] Take 30g of ternary block copolymerized silicone oil with a molecular weight of about 11000 and 0.3g of epichlorohydrin into a 100mL three-necked flask, stir and heat up to 105°C, after 1.0h of reaction, add 0.45g of triethanolamine into the bottle, and continue to Stir and react at 110°C for 2 hours. After the reaction is completed, the product organosilicon quaternary ammonium salt fabric finishing agent I is obtained.

[0026] Emulsification process: Take 30g of the product, pour it into a 250mL beaker, add 10 drops of acetic acid first, then slowly add 70g of 0.1% acetic acid solution dropwise, stir quickly until clear, and obtain a silicone quaternary ammonium salt fabric finishing agent I emulsion with a content of 30% .

Embodiment 2

[0028]

[0029] Take 30g of ternary block copolymerized silicone oil with a molecular weight of about 11000 and 0.3g of epichlorohydrin into a 100mL three-necked flask, stir and raise the temperature to about 95°C for 2.5h. After the reaction is completed, the ring-opening addition reaction product is obtained. Continue to add 0.25g of triethylamine into the bottle, and continue to stir and react at 120°C for 1.5h. After the reaction is completed, the product organosilicon quaternary ammonium salt finishing agent II is obtained.

[0030] Emulsification process: Take 30g of the product, pour it into a 250mL beaker, first add 10 drops of acetic acid, then slowly add 70g of 0.1% acetic acid solution dropwise, stir quickly until clear, and obtain a silicone quaternary ammonium salt fabric finishing agent II emulsion with a content of 30% .

Embodiment 3

[0032]

[0033] Take 30g of ternary block copolymerized silicone oil with a molecular weight of about 6000 and 0.5g of epichlorohydrin into a 100mL three-necked flask, stir and heat up to about 100°C for 2.0h, then add 0.7g of triethanolamine into the bottle, and continue to Stir and react at 90°C for 4 hours. After the reaction is completed, the product organosilicon quaternary ammonium salt fabric finishing agent III is obtained.

[0034] Emulsification process: Take 30g of the product, pour it into a 250mL beaker, add 10 drops of acetic acid first, then slowly add 70g of 0.1% acetic acid solution dropwise, stir quickly until clear, and obtain a silicone quaternary ammonium salt fabric finishing agent III emulsion with a content of 30% .

Abstract

The invention belongs to the technical field of fine chemical engineering, and particularly relates to an organosilicon quaternary ammonium salt fabric finishing agent based on block silicone oil anda preparation method thereof. The preparation method comprises the following specific steps: adding epoxy chloropropane into ternary block copolymerized silicone oil, and performing heating reaction to obtain a block silicone oil intermediate containing chlorinated hydrocarbon branched chains; and adding triethylamine or triethanolamine, and continuously performing heating reaction for a period oftime to obtain the organosilicon quaternary ammonium salt fabric finishing agent based on block silicone oil. The finishing agent is high in softness and stability and has small influence on whiteness and hydrophilicity and a quaternary ammonium salt structure, and the quaternary ammonium salt structure is high in antibacterial capability; moreover, fabric is endowed with excellent antibacterialperformance, and the fabric can be endowed with other good effects such as softness, smoothness and elasticity; and the organosilicon quaternary ammonium salt fabric finishing agent has high practicalvalue and a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a class of organosilicon quaternary ammonium salt fabric finishing agents based on block silicone oil and a preparation method thereof. Background technique [0002] With the improvement of living standards, people's requirements for environmental sanitation are getting higher and higher, their self-protection awareness is increasing, and they pay more and more attention to the comfort and health care functions of clothing. There are a large number of various microorganisms on clothing and fabrics. Although most of these microorganisms are non-pathogenic, their reproduction can cause abnormal irritation to human skin. Human skin sweat, sebum and epidermis provide suitable conditions for bacteria to multiply; under the action of bacteria, it is easy to decompose to produce odor, form mold, and induce skin diseases and infectious diseases. Therefore, the antiba...
