Problems solved by technology

The current reloading is generally simple bonding, which is very effective in a short time, but the long-term ultraviolet light irradiation can cause the adhesive to decompose itself under the action of the photocatalyst, causing the catalyst to fall off and affecting the effect.

Abstract

The invention relates to a method for preparing air auto-purification functional fabrics with a photocatalyzed coating, which comprises the following steps: firstly, a base cloth is subjected to surface treatment by an organic solution at a temperature of between 60 and 70 DEG C; secondly, deionized water, methanol and ether are taken as dispersing reagent of a fiber protecting agent, the pH value of the dispersing protecting agent is adjusted to between 9.5 and 11.5 by ammonia, and the base cloth is immersed in the dispersing protecting agent for more than 6 to 8 hours at a temperature of between 30 and 40 DEG C; thirdly, the base cloth is treated for 10 to 15 minutes by an ethylenediaminetetraacetic acid and a phytate aqueous solution; and fourthly, photocatalyst is added in a coating agent, and the coating agent is then directly coated on the base cloth by a scraper with the coating amount between 6 and 15 grams per square meter, and dried for 2 to 4 minutes at a temperature of between 110 and 120 DEG C to obtain the air auto-purification functional fabrics. The air auto-purification functional fabrics have good air purification effect; the preparation technology is simple; and the method is easy to operate and is used for industrial mass production.

Description

technical field [0001] The invention belongs to the field of preparation of air self-purifying functional fabrics, in particular to a preparation method of photocatalytic coated air self-purifying functional fabrics. Background technique [0002] In recent years, with the improvement of living standards, a large number of new decorative materials, furniture and daily necessities have continuously entered the room, and the resulting indoor environmental pollution has become increasingly serious. Aiming at the increasingly serious indoor air pollution, scientific researchers are actively involved in the prevention and purification of indoor air pollution, and a large number of indoor air purification technologies and related products have emerged. Many scientific researchers have successively researched and developed a variety of air purification materials. Among them, the air purification materials based on photocatalytic technology are characterized by their high photocataly...
