Problems solved by technology

Finishing white or light-colored fabrics tends to turn yellow
The fabric finished with amino silicone oil is not hydrophilic enough, and its hygroscopicity is not strong. It is easy to form oil spots and static electricity when used in chemical fiber fabrics or cotton and chemical fiber blended fabrics. When finishing fabrics with general epoxy modified silicone oil, although there are Very good hydrophilicity, but its softness and smoothness are not enough, and it is astringent; the stability of the prepared emulsion is poor, the moisture absorption rate is not high, and the waste is large; the silicone oil modified with polyether, because it is only a simple hydrogen bond, Relatively poor fastness and softness
Therefore, the existing technology needs to be updated and improved

Embodiment 1

[0034] A. In the reactor equipped with stirring, start stirring, and then add 92 parts of octamethylcyclotetrasiloxane, 3 parts of high hydrogen-containing silicone oil (brand XFC202), 2 parts of end-capping agent (hexamethyldisiloxane Oxygen, grade HX-18), 3 parts of hydrochloric acid, mix evenly, react at 60°C for 11 hours, the material in the reactor turns from muddy to transparent, after the reaction, cool down to 25°C with jacketed cooling water, Adjust the pH to 6 under these conditions, and then take a sample to detect that the hydrogen content is 0.05%, and the viscosity measured by a rotational viscometer is 500mPa.s, and a colorless and transparent low-hydrogen silicone oil is prepared for use in the next step.

[0035] B. Transfer 89.9 parts of low hydrogen-containing silicone oil, 0.1 part of catalyst (chloroplatinic acid, brand NMC2505), and 10 parts of glycidyl ether (alkenyl epoxy compound) into a reactor equipped with a stirrer and connected with a supporting co...

Embodiment 2

[0038] A. In the reactor equipped with stirring, start stirring, and add 92 parts of cyclotetrasiloxane mixture, 3 parts of high hydrogen-containing silicone oil, 2 parts of end-capping agent (hexamethyldisiloxane), 3 parts Parts of phosphoric acid were mixed evenly, and reacted at 100°C for 7 hours. The material in the reactor turned from muddy to transparent. After the reaction, the cooling water in the jacket was used to cool down to 25°C, and then the pH was adjusted to 6 under this condition. The hydrogen content is 0.05%, the viscosity measured by a rotational viscometer is 480mPa.s, and a colorless and transparent low-hydrogen silicone oil is obtained.

[0039] B. Add 89.9 parts of low-hydrogen silicone oil, 0.1 part of catalyst (chloroplatinic acid), and 10 parts of 1-vinyl-3,4-epoxycyclohexane, and stir the reaction for 8 hours at 100°C. Then, the low-boiling point substances were evaporated under the vacuum condition of 0.09MPa to obtain a colorless and transparent e...

Embodiment 3

[0042] A. In the reactor equipped with stirring, start stirring, and add 70 parts of octamethylcyclotetrasiloxane, 25 parts of high hydrogen-containing silicone oil, 2 parts of end-capping agent (hexamethyldisiloxane), Mix 3 parts of sulfuric acid evenly, and react at 120°C for 6 hours. The material in the reactor turns from muddy to transparent. After the reaction, cool down to 25°C with jacketed cooling water, and then adjust the pH to 6 under this condition. The measured hydrogen content is 0.4%, and the viscosity measured by a rotational viscometer is 600 mPa.s, and a colorless and transparent low hydrogen-containing silicone oil is obtained.

[0043] B. Transfer 74.9 parts of low hydrogen-containing silicone oil and 0.1 part of catalyst (chloroplatinic acid) obtained in the previous step into a reactor equipped with a stirrer and connected with a supporting condenser, and add 25 parts of 1-vinyl-3, 4-epoxycyclohexane was reacted at 120°C for 6 hours, and the low boiling p...

Abstract

The invention discloses a preparation method of hydrophilic amino silicone oil. The invention is characterized in that the preparation method comprises the following steps: A. the preparation of low-hydrogen silicone oil: siloxane ring body, high-hydrogen silicone oil, blocking agent and acid are mixed for reaction and are cooled, and the pH is adjusted; B. the preparation of epoxy silicone oil: the prepared low-hydrogen silicone oil, alkenyl epoxy compound and catalyst are mixed for reaction and are cooled; and C. the preparation of hydrophilic amino silicone oil: the prepared epoxy siliconeoil, organic amine and solvent are mixed for reaction, and the solvent is distilled. The bonding is firmer in the form of a chemical bond when the hydrophilic amino silicone oil prepared by the method reacts with the fabric, and the hydrophilic amino silicone oil is washable, has soft effect of the common amino silicone oil, no yellowing and good smoothness and antistatic property, and can be widely used in fabric finishing.

Description

technical field [0001] The invention relates to a preparation method of a fabric softening and finishing agent, in particular to a preparation method of hydrophilic amino silicone oil. Background technique [0002] People's requirements for clothing are not simply to require fabrics to be hygroscopic, breathable, and comfortable to wear, but also to pursue soft, smooth, and elegant styles of fabrics. Therefore, softeners appear, and the most widely used ones today are Silicone softener. Silicone softeners were first researched, developed and applied in European and American countries, and made huge profits. Since the reform and opening up, my country's economy has developed rapidly, and the textile printing and dyeing industry has developed from the use of silicone softeners to the gradual application, and now it is fully applied. my country has joined the WTO for many years, and the most competitive industrial products in the international market are textile products; for...
