Problems solved by technology

[0012] and currently used fabric coating agents are mainly divided into several categories such as polyacrylate, polyurethane and silicone, although polyacrylate and polyurethane fabric coating agents It has a wide range of uses, but it also has disadvantages such as poor moisture permeability, poor surface finish, and difficulty in adjusting the hand feel. It is difficult to meet the development needs of high-end fabric coating finishing; although silicone-based fabric coating agents have low surface energy and high temperature resistance, they are often used The treated fabric is smooth, soft, and has good moisture permeability and air permeability, but has low adhesion to the fabric and poor washing resistance

Embodiment 1

[0037] Add 200 g of dimethylcyclosiloxane mixture, 120 g of tetramethyltetravinylcyclotetrasiloxane and 0.9 g of potassium hydroxide successively into the reaction kettle equipped with stirrer, thermometer and condenser tube, under nitrogen protection Raise the temperature to 150 o C. After constant temperature reaction for 3 h, after depressurized distillation to remove small molecular water, a transparent oily high-reactivity silicone oil was obtained.

[0038] Add 200 g of dimethylcyclosiloxane mixture, 8 g of allyltrimethoxysilane, 0.5 g of trimethylethoxysilane and 0.8 g of hydrogen into a reaction kettle equipped with a stirrer, a thermometer, and a condenser Potassium oxide, under the protection of nitrogen, the temperature was raised to 180 o C. After constant temperature reaction for 4 hours, after decompression distillation to remove small molecular water, a transparent oily thixotropic ultra-high molecular weight silicone oil was obtained, with a molecu...

Embodiment 2

[0043] Same as Example 1, but the amount of highly reactive silicone oil in step (4) is changed from 100 g to 120 g, the amount of thixotropic ultra-high molecular weight silicone oil is changed from 100 g to 80 g, and the others remain unchanged.

Embodiment 3

[0045] Same as Example 1, but the amount of highly reactive silicone oil in step (4) is changed from 100 g to 80 g, the amount of thixotropic ultra-high molecular weight silicone oil is changed from 100 g to 120 g, and the others remain unchanged.

Abstract

The present invention belongs to the technical field of chemical industry, and specifically relates to an organic / inorganic nanometer function particle modified organosilicon fabric coating agent preparation method. The preparation method comprises: adopting an anion ring opening polymerization process to synthesize hyperreactivity silicone oil, a special cross-linking agent, and silicone oil having thixotropy and ultra-high molecule weight; carrying out molecule penetration melting of the hyperreactivity silicone oil, the special cross-linking agent, and the silicone oil having thixotropy and ultra-high molecule weight to synthesize an organosilicon coating agent base gum; and finally adopting a high energy dispersing device to uniformly wrapping nanometer hollow silica microspheres and polymer hollow microspheres into the organosilicon coating agent base gum under a strong shear condition to obtain the organic / inorganic nanometer function particle modified organicsilicon fabric coating agent. With the organic / inorganic nanometer function particle modified organicsilicon fabric coating agent, good crisp hand feeling and slick feeling can be provided for the coated fabric coating, and strength, hydrostatic pressure resistance and waterproof moisture permeation performance of the fabric coating can be significantly improved without influence on softening and comfort of the fabric.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and relates to a modified organic silicon fabric coating agent and a preparation method thereof, in particular to a preparation method of an organic / inorganic nano functional particle modified organic silicon fabric coating agent. Background technique [0002] With the development of science and technology and the improvement of living standards, people's requirements for quality of life are getting higher and higher. Textiles have extended from the basic function of covering the body to keep out the cold to the functions of beauty, comfort, protection, fashion, etc. All kinds of intelligent and functional textiles have been widely concerned and developed. [0003] In recent years, the development of functional textiles has been extremely rapid, mainly in climate adaptation functions (such as temperature maintenance, waterproof and moisture-permeable, windproof and water-repellent, etc....
