Description
Technical Field
The invention relates to a construction method of an ultra-wear-resistant special-wettability anti-ultraviolet functional fabric.
Background
The hydrophobic phenomenon has been noticed and studied as a common wetting phenomenon, and young's equation about interfacial tension and wetting property was proposed in tomas-young as early as 1805. The discovery of the lotus leaf effect in 1997 then led to a new era in the research of superhydrophobic surfaces. By superhydrophobic surface is meant a surface where the contact angle of a drop of water with the interface is greater than 150 ° and the rolling angle is less than 10 °. At present, the preparation of superhydrophobic surfaces is mainly through two routes: (1) a rough structure is constructed on the surface (2), and a low surface energy substance is modified on the surface. However, the super-hydrophobic effect cannot be achieved by simply modifying the low surface energy substance, so how to construct the rough structure of the surface becomes the key point for constructing the super-hydrophobic surface. The common construction methods are reported to mainly comprise a hydrothermal method, an electrostatic spinning method, a plasma etching method and a laser femtosecond etching method, the methods either need complicated processes or expensive instruments and are difficult to apply to large-scale industrial production, and more importantly, the rough structure constructed by the methods is easy to collapse under the action of external force to lose the superhydrophobic property. Therefore, how to construct the super-hydrophobic surface with low cost so that the super-hydrophobic surface has special protective properties such as friction resistance, soaping resistance, acid and alkali resistance, ultraviolet resistance and the like, and is suitable for large-scale industrial production is an important problem.

(2) preparing the super-hydrophobic ultraviolet-resistant fabric by a hot-pressing method: placing the fabric obtained in the step at a pressure of 0-3 Kg/cm2Under the pressure of (3), reacting at the temperature of 20-200 ℃ for 3 min-1 day, and taking out after the reaction is finished to obtain the fabric with the ultra-wear-resistant special wettability and anti-ultraviolet function.
Further, in the step (1), the acid is any one of hydrochloric acid or acetic acid.
Further, the solvent in the step (1) is a polar or non-polar solvent.
Further, in the step (1), the solvent is any one of water, DMF, ethanol or toluene.
Further, in the step (1), the silane coupling agent is any one or more of octadecylsiloxane, OTES, PDES, PTES, chlorosilane, silazane and siloxane compounds.
Further, the fabric in the step (1) is any one of woven fabric, non-woven fabric, knitted fabric or inorganic material fabric of natural or artificial fiber.
Further, the natural or artificial fiber woven fabric is any one of cotton, hemp, silk, wool, terylene, polypropylene fiber, polyamide fiber, spandex, acrylic fiber or viscose, and the inorganic material fabric is glass fiber, carbon fiber or asbestos fiber.
