Abstract

The invention discloses a super-hydrophobic fabric and a preparation method thereof and belongs to the technical field of super-hydrophobicity. The super-hydrophobic fabric comprises a fabric body, wherein a coupling agent wear-resistant layer is stuck to the surface of the fabric body, a super-hydrophobic layer is stuck to the surface of the coupling agent wear-resistant layer, the coupling agent wear-resistant layer contains a coupling agent A, and the super-hydrophobic layer is a coupling agent B modified nanoparticle layer. The super-hydrophobic fabric disclosed by the invention contains the coupling agent wear-resistant layer and the super-hydrophobic layer, and the coupling agent wear-resistant layer can be used for improving the wear resistance of the super-hydrophobic layer, so that the super-hydrophobic fabric can keep a super-hydrophobic effect in a long-acting manner.

Description

technical field [0001] The invention relates to the field of superhydrophobic, in particular to a superhydrophobic fabric suitable for various fabric surfaces and a preparation method thereof. Background technique [0002] The superhydrophobic surface originated from the "lotus leaf effect" in nature. The study on the surface of lotus leaf found that the existence of micro-nano rough structure and low surface energy substances are two necessary conditions for super-hydrophobic surface. At present, various sols are generally used to form micro-nano structures on the surface of fabrics. For example, Chinese patent application CN101397754A prepares superhydrophobic cotton fabric by immersing the fabric in silica sol, then drying it, and finally modifying it with low surface energy substances; Chinese patent application CN104594028A processes multi- Carboxylic acid modified cellulose fabrics to obtain superhydrophobicity directly on the surface of cellulose fabrics.
