Problems solved by technology

As mentioned above, under the irradiation of light, the photocatalyst will produce a photocatalytic reaction similar to photosynthesis, produce free hydroxyl groups and active oxygen with strong oxidation ability, and have a strong photoredox function, so the unit volume of the photocatalyst The larger the surface area of ​​the photocatalyst, the stronger the effect of the photocatalytic reaction, and the more free hydroxyl groups and active oxygen are produced. It can be said that the particle size is a key indicator of the quality of the photocatalyst, which requires the photocatalyst to be prepared and subsequently stored and used. process, not only TiO 2 The particle size should be small enough, and TiO 2 Agglomeration cannot occur, affecting the photoreactive area

Abstract

The invention discloses a method for consolidation of photocatalyst nano TiO2 hydrosol in fabric and photocatalyst fabric. During production, the fabric walking speed is limited at 20-40m / min, the hydrosol temperature is maintained at 20-60DEG C, and the shaping and drying temperature is 160-180DEG C. The limitation purpose of the technological conditions is that the solid content of the finally produced photocatalyst fabric surface TiO2 hydrosol reaches more than 80% so as to improve the stability of the photocatalyst fabric product and the final catalytic properties of the photocatalyst.

Description

technical field [0001] The invention relates to the field of photocatalytic materials, in particular to photocatalyst nano TiO 2 Method for consolidating hydrosol on fabric and photocatalyst fabric. Background technique [0002] Photocatalyst is a kind of nanoscale TiO 2 The general term for photo-semiconductor materials represented by photocatalysis is an ideal material for controlling indoor environmental pollution in the world. Under the action of light, it produces a strong catalytic degradation function and can effectively degrade toxic and harmful gases such as formaldehyde in the air. , can effectively kill a variety of bacteria, the antibacterial rate is as high as 99.99%, and can decompose and harmlessly treat the toxins released by bacteria or fungi, and also have deodorizing, antifouling and other functions. [0003] In recent years, due to the emergence of "decoration pollution syndrome", the problem of indoor environmental pollution has become a hot spot of co...
