Problems solved by technology

And the uniform dispersion of micro-nano particles in the finishing agent and uniform finishing on the fabric are technical problems
(2) The durability of the superhydrophobic effect is not high during use
Moreover, the damaged hydrophilic structure is easy to adhere to other substances to breed bacteria, and the growth of bacteria will further aggravate the damage of its hydrophobic structure, which will bring harm to the human body or cause inconvenience to use.

Abstract

The invention provides a manufacturing method of super-hydrophobic fabric and the super-hydrophobic fabric. The manufacturing method comprises the following steps that tetrabutyl titanate is hydrolyzed, so that titanium dioxide sol is obtained; silver ions and amphiphilic polymers are subjected to a complex reaction, so that the amphiphilic polymers with the complex silver ions are obtained; the amphiphilic polymers with the complex silver ions are added to the titanium dioxide sol to form mixed sol, and siloxane is added to the mixed sol to conduct a reaction, so that siloxane modified sol isobtained; and the siloxane modified sol is adopted to neaten fabric, so that the nano titanium dioxide and nano-silver combined super-hydrophobic fabric is obtained. The manufacturing method is easyand convenient to operate, and is beneficial to improve the production efficiency and save the cost, the super-hydrophobic fabric has the lasting and efficient hydrophobic effect, the self repair of the hydrophobic performance of the fabric can be achieved, and the super-hydrophobic fabric has a good self repair effect on the surface breakage caused by mechanical friction and chemical oxidation and has the excellent antibacterial property.

Description

technical field [0001] The invention relates to a method for preparing a superhydrophobic fabric and the superhydrophobic fabric, in particular to a method for preparing a superhydrophobic fabric with high efficiency, durability, self-repairing and antibacterial functions and the superhydrophobic fabric. Background technique [0002] The wettability of the surface of the material is directly related to its surface microstructure and surface energy. The surface obtained through surface treatment has a hydrophobic or even super-hydrophobic interface, which has good self-cleaning, anti-icing, and corrosion resistance. It has broad application prospects in biomedicine, agricultural production and people's daily life. Superhydrophobic textiles based on flexible fabrics have a wide range of applications in outdoor clothing fabrics and outdoor engineering textiles. The current basic preparation method of superhydrophobic textiles is to use low surface energy additives to finish th...
