Preparation method of self-cleaning lamp tube glass

Abstract

The invention discloses a preparation method of self-cleaning lamp tube glass. The preparation method comprises the following steps: S1, preparing the lamp tube glass; S2, immersing the obtained lamptube glass into deionized water for cleaning for 5-10 minutes, immersing the cleaned lamp tube glass into a mixed solution, heating until the mixed solution is boiled, keeping the boiling state for 10-15 minutes, and taking the lamp tube glass out, and naturally drying the lamp tube glass to obtain a standby lamp tube; S3, adding 100-200 mL of a sodium alginate solution with the mass fraction of 1% into the suspension, carrying out stirring and mixing for 20-30 min, then adding 1.5-2.0 mL of a glutaraldehyde solution with the mass fraction of 20%, and carrying out stirring and reacting for 3-4h to obtain a reaction solution; and S4, coating the surface of the standby lamp tube with the reaction solution through a coating device with the coating thickness of 3-5 [mu] m, putting the lamp tube into a vacuum oven after coating, and drying the lamp tube at 60-80 DEG C for 8-10 h to obtain the self-cleaning lamp tube glass.

Description

technical field [0001] The invention relates to the technical field of inorganic chemistry, in particular to a method for preparing self-cleaning lamp tube glass. Background technique [0002] Self-cleaning glass is a kind of eco-environmental glass that photocatalytically degrades dirt, referred to as self-cleaning glass, or self-cleaning glass. It is to coat one or more layers of n-type semiconductor films on the surface of the glass, and use the photo-generated holes and electron pairs generated by the semiconductor to radiate light. The photo-generated holes have a strong oxidation ability, which can remove some toxic pollutants and reduce pollution. Purpose. [0003] Coating devices are often used when preparing self-cleaning glass. The existing coating devices do not handle the reaction liquid enough, which may easily cause the reaction liquid to condense, which will affect the subsequent coating work. When stirring the reaction liquid The stirring method is single, ...

Problems solved by technology

[0007] The existing coating device does not handle the reaction liquid enough, which easily causes the reaction liquid to condense, which affects the subsequent coating work. When the reaction liquid is stirred, the stirring method is single, resulting in insufficient stirring and affecting the quality of the reaction liquid; The existing coating device lacks a spray mechanism, and directly coats the object, so that the contact area between the object and the reaction solution is small, resulting in uneven coating and affecting the coating quality; the existing coating device lacks a cleaning mechanism, A large amount of reaction liquid remains on the conveyor belt, which may cause uneven coating on uncoated objects and affect the coating quality
