Abstract

The invention discloses a preparation method of a flame-retardant/super-hydrophobic cotton fabric and belongs to the technical field of functional materials. The method disclosed by the invention comprises the following steps of: (1) cleaning and drying a cotton fabric; (2) carrying out amination on nano-zinc oxide particles via aminopropyl methyl diethoxysilane with alcohol as a solvent; (3) preparing an acetone solution containing epoxy resin, soaking the clean cotton fabric into the acetone solution for epoxidation; (4) soaking the cotton fabric after the epoxidation into the mixed solution obtained in the step (2), taking out the cotton fabric and then putting the cotton fabric into a clean watch glass, and drying at room temperature; and (5) preparing a hydrophobic modified solution, soaking the cotton fabric obtained in the step (4) into the hydrophobic modified solution for modification, bleaching by using methanol, and drying to obtain the flame-retardant/super-hydrophobic cotton fabric. The preparation method of the flame-retardant/super-hydrophobic cotton fabric has the advantages of simple process, low economic cost, short period, small energy consumption, no need of complex special devices and no various follow-up problems, thereby having great application prospect.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a method for preparing a flame-retardant / super-hydrophobic cotton fabric with a micro-nano hierarchical structure. Background technique [0002] Superhydrophobic surfaces have very broad application prospects. Studies have shown that super-hydrophobic surfaces, applied to glass, concrete, wood and other building materials, can make the material surface have self-cleaning function; applied to textiles such as clothing, can achieve waterproof, anti-pollution and self-cleaning effects; applied to high snowfall areas On satellite antennas, it can prevent snow from interfering or interrupting signals; when applied to windshields of cars, airplanes, spacecraft, etc., it can not only reduce the pollution of dust and other pollutants in the air, but also make it safe in high humidity or rainy days Maintain a clean state in the environment to avoid accidents due ...
