Problems solved by technology

However, because amino silicone oil has amino groups on the side chain and contains active hydrogen atoms, it is easy to be oxidized and turn yellow. In addition, it is necessary to add an emulsifier to increase the hydrophilicity.

Embodiment 1

[0016] Embodiment 1: In this embodiment, the steps of the synthesis method of epoxy quaternized modified amino silicone oil are as follows:

[0017] (1) Synthesis of amino silicone oil: Add stoichiometric N-β-aminoethyl γ-aminopropylmethyldimethoxysilane (KH- 602), octamethylcyclotetrasiloxane linear body (D4 linear body), end-capping agent hexamethyldisiloxane (MM), catalyst potassium hydroxide and deionized water; the above four main substances participating in the reaction The combined dosage is calculated in molar mass percentage as:

[0018] Octamethylcyclotetrasiloxane linear body (D4 linear body) 87%

[0019] N-β-aminoethylγ-aminopropylmethyldimethoxysilane (KH-602) 12%

[0020] Capping agent hexamethyldisiloxane (MM) 0.5%

[0021] Catalyst potassium hydroxide 0.5%

[0022] The add-on of deionized water, its molar mass number is suitable with the molar mass that octamethylcyclotetrasiloxane linear body (D4 linear body) adds;

[0023] Heat the above compounded mixtu...

Abstract

The invention relates to a method for synthesizing epoxy quaternization modified amino-silicone oil, pertaining to the technical field organic silicide amino-silicone oil preparation. The method includes the following main procedures: (1) synthesis of amino-silicone oil: the raw material of octamethylcy-clotetrasiloxane (D4 linear body), N-Beta-aminoethylGemma- aminopropylmethyldimethyoxysilane (KH-602), hexamethyl dimethyl siloxane (MM), catalyst potassium hydroxide and deionized water are placed in a reactor for reaction for 5-6 hours under 100-110 DEG C, and the desired amino-silicone oil is achieved after being cooled; (2) proper amount of epichlorohydrin is added for reaction under 80 DEG C, the amino-silicone oil is processed by epoxy quaternization to achieve epoxy quaternary ammonium salt amino-silicone oil; (3) the quaternary ammonium salt amino-silicone oil is emulsified by deionized water, water is slowly added under 85 DEG C and stirred, and the water miscible liquid of epoxy quaternization modified amino-silicone oil is finally achieved. The product achieved by the method is applicable to textile fabric neatening and has pilling resistant and fluffing resistant properties.

Description

technical field [0001] The invention relates to a method for forming epoxy quaternized modified amino silicone oil, which belongs to the technical field of preparation technology of organosilicon compound amino silicone oil. Background technique [0002] Amino silicone oil is a kind of cationic silicone oil, which is combined with fibers. It is an important finishing aid for fibers (such as fabrics, paper, leather, etc.), which can improve the feel of fiber products and make them soft, smooth and elastic. , anti-wrinkle, antistatic properties, etc., and non-toxic. In addition, amino silicone oil is also widely used in the fields of resin modification, cosmetics and coatings. In addition, high-viscosity amino silicone oil can also give polyester / cotton blended fabrics a plump, cotton-like feel; while lower-viscosity amino silicone oil can give the fabric a smooth silky feel. This is because the amino functional group has a strong polarity and interacts with the hydroxyl grou...
