Problems solved by technology

However, most of these methods are complex and multi-step, the process control is difficult, special equipment is required, and some methods are limited to flat surfaces of some special materials, which are difficult to be widely used
Moreover, when the special micro-nano structure of the super-hydrophobic surface is destroyed, the material will also lose its super-hydrophobic properties. To endow the material with super-hydrophobic properties again, more complex processing is required, which is time-consuming and labor-intensive.

Abstract

The invention discloses a multifunctional super-hydrophobic textile finishing agent, and a preparation method and applications thereof. The preparation method comprises following steps: a precursor of an oxide sol and a graphite oxide aqueous dispersion are dispersed in deionized water, an anionic surfactant is added, a catalyst is added for hydrolysis and condensation reaction after uniform dispersion so as to obtain a mixed reaction system, and the mixed reaction system is heated to 30 to 50 DEG C for 3 to 12h of reaction so as to obtain a hydrosol; a functional agent is added into the hydrosol so as to obtain the multifunctional super-hydrophobic textile finishing agent. The multifunctional super-hydrophobic textile finishing agent is safe, is friendly to the environment, is excellent in effect, is used for super hydrophobic and multifunctional finishing of textile, is capable of providing textile with six functions including super-hydrophobic property, flame resistance, antibacterial property, stain resistance, ultraviolet resistance, and skin protection performance, is capable of eliminating adverse effect of the plurality of functions, improving the synergistic effect; the preparation method is simple and convenient, is easy to control, and is suitable for large scale production.

Description

technical field [0001] The invention relates to a preparation method of a multifunctional superhydrophobic textile finishing agent, in particular to a preparation method and application of a multifunctional superhydrophobic textile finishing agent prepared by a sol-gel method, and belongs to the technical field of textile multifunctional finishing. Background technique [0002] Superhydrophobic materials not only have important uses in daily life, but also have a very wide range of practical application values ​​in clothing, construction, glass, automobiles, equipment casings and other fields. Superhydrophobic fabrics are gradually favored by people because of their special wetting properties, as well as waterproof, oil-proof, anti-fouling, anti-corrosion, anti-icing and self-cleaning properties. It is generally considered that a solid surface with a contact angle greater than 150° with water droplets is a superhydrophobic surface. The water droplet is spherical on the surf...
