Abstract

The invention relates to the technical field of super-hydrophobic materials, in particular to a preparation method of a super-hydrophobic fabric. The preparation method comprises the following steps:(1) by using octadecylamine as a raw material, preparing a nano octadecylamine finishing agent by using an ultrasonic dispersion method; (2) performing suction filtration on the nano octadecylamine finishing agent obtained in the step (1) by using a vacuum suction filtration method, and depositing the nano octadecylamine finishing agent on the surface of the fabric; and (3) heating the fabric obtained in the step (2) to obtain the super-hydrophobic fabric. According to the preparation method of the super-hydrophobic fabric, the super-hydrophobic property of the surface of the fabric is achieved, the static contact angle of the surface of the prepared super-hydrophobic fabric can reach 152 degrees, the super-hydrophobic fabric has good friction resistance, washing resistance and ultravioletresistance, meanwhile, less instruments and equipment are used, the steps are simple, the time is short, the original color of the fabric is not changed, operation is simple and convenient, the preparation process is carried out in a water system, and the preparation method is simple and friendly to the environment.

Description

technical field [0001] The invention belongs to the technical field of superhydrophobic materials, and in particular relates to a preparation method of superhydrophobic fabrics. Background technique [0002] Based on the enlightenment of superhydrophobic surfaces such as lotus leaves, water strider legs, butterfly wings, and mosquito compound eyes in nature, bionic construction of superhydrophobic surfaces has become an important research direction in the field of surface interfaces in recent years. Although the bionic superhydrophobic surface has broad application prospects in the fields of self-cleaning, anti-fouling, drag reduction, anti-fog, anti-icing, corrosion resistance, and oil-water separation. However, the construction process of most artificial superhydrophobic surfaces is relatively complicated, and the surface microstructure and low surface energy chemical substances have poor stability, short life, and are easy to lose their superhydrophobic properties when su...
