Description

Technical Field

[0001] The present invention relates to the technical field of fabric treatment, and specifically, to an easily soluble antistatic agent, a preparation method, and an application thereof. Background Art

[0002] Chemical fibers (abbreviation: chemical fiber), compared with natural fibers, have the advantages of low price, easy manufacturing, good toughness, and high strength, and thus have been widely used. However, chemical fibers also have the problem of easy charge accumulation and static electricity generation, so the fabric must be antistatically treated.

[0003] One of the antistatic treatment methods is to add substances such as carbon nanotubes, carbon fibers, and graphene to it. However, the solubility of these substances is a technical problem existing in the current treatment. It must be fully dispersed before application. If it is not fully dispersed, it is easy to cause problems such as precipitation or disappearance of antistatic properties. Summary of the Invention

[0004] The technical problem solved by the present invention:

[0005] To solve the problem of poor antistatic effect caused by insufficient dispersion of the existing antistatic agent.

[0006] The technical solution adopted by the present invention:

[0007] Aiming at the above technical problems, the purpose of the present invention is to provide an easily soluble antistatic agent, a preparation method, and an application thereof.

[0008] The specific content is as follows:

[0009] First, the present invention provides a preparation method of an easily soluble antistatic agent, including the following steps:

[0010] S1 GO is dispersed by a solvent to form a dispersion liquid, and polyvinyl alcohol is added thereto; after a hydrothermal reaction, modified GO is obtained;

[0011] S2 The modified GO, solvent, and surfactant are dispersed to obtain a pretreatment product;

[0012] S3 Waterborne polyurethane is added to the pretreatment product and then dispersed to obtain a finished product;

[0013] The surfactant includes O,O'-bis(phenyl)dithiophosphoric acid-N,N-diethylammonium, α-olefin sulfonate, and glycosyl quaternary ammonium salt.

[0014] Second, the present invention provides an easily soluble antistatic agent obtained by the above-mentioned preparation method.

[0015] Third, the present invention provides an application of the above-mentioned easily soluble antistatic agent in fabrics.

[0016] Beneficial effects achieved by the present invention:

[0017] By using the easily soluble antistatic agent provided by the present invention, which is dispersed in waterborne polyurethane through GO, polyvinyl alcohol, and surfactant. Polyvinyl alcohol binds to multiple active sites on the surface of GO, and then it is introduced into waterborne polyurethane. Utilizing the nano-effect and functionality of GO, the purpose of improving the conductive performance is achieved. Through the hydrothermal treatment of GO and polyvinyl alcohol for assembly, the oxygen-containing groups on the surface of GO enable modifiable active sites, which can further enhance the binding strength with polyvinyl alcohol. At the same time, the sulfonic acid groups provided by α-olefin sulfonate in the surfactant can interact with the hydroxyl groups on the surface of GO through hydrogen bonds, thereby enhancing the compatibility of GO with the system, further improving the dispersibility of GO, and reducing its precipitation. By using the surfactants of the present application (O,O'-bis(phenyl)dithiophosphoric acid-N,N-diethylammonium, α-olefin sulfonate, glycosyl quaternary ammonium salt), through the compounding of anions and cations, good synergistic effect can be shown. In addition, O,O'-bis(phenyl)dithiophosphoric acid-N,N-diethylammonium has high surface activity, and the surfactant obtained by compounding it with others can further improve the stability of the system.
