Problems solved by technology

[0005] However, the reaction process of ordinary photocatalytic products depends on photon excitation. Only when the photocatalyst obtains enough energy to make the valence band electrons undergo energy band transition, can it have photocatalytic oxidation decomposition ability.
Therefore, the placement of decorations, weather conditions, and the change of day and night will all affect the use of photocatalytic artificial flowers, which greatly limits their application.

Embodiment 1

[0025] The surface of the glass ornament is pretreated, and after removing the oil and dust on the surface, the nano-SrAl 2 o 4 : Eu, Dy light-storing material (the light-emitting wavelength is about 520nm, and the brightness is 400mcd / m when light-emitting for 10 minutes 2 , the afterglow time is up to 60h); the coating solution obtained after mixing with a preset solvent is uniformly coated on the surface of the substrate by a dipping process, and then treated at a temperature of 120°C to obtain the light storage film layer 2, the film layer The thickness is 40 microns; finally, the visible light-responsive nano-TiO 2 The base photocatalytic spraying agent is sprayed onto the surface of the light storage film layer 2, and heat-treated at a temperature of 120°C to obtain the photocatalytic purification film layer 3 with a film thickness of 20 microns, so that the glass decoration can achieve all-weather Environmental purification function.

Embodiment 2

[0027] Pretreat the surface of the glass ornament, remove the oil stains and dust on the surface, firstly apply the nano-Sr 2 MgSi 2 o 7 : Eu, Dy light-storing material (light emission wavelength is about 466nm, afterglow time up to 20h); the coating solution obtained after mixing with a preset solvent, and then uniformly coated on the surface of the substrate by dipping process at a temperature of 40°C Process to obtain the light storage film layer, the thickness of the film layer is 0.05 microns; finally, the visible light responsive nano-TiO that matches the light storage film layer 2 2 The base photocatalytic spraying agent is sprayed onto the surface of the light-storing film layer 2, and heat-treated at a temperature of 40°C to obtain the photocatalytic purification film layer 3 with a film thickness of 0.02 microns, so that the glass decoration can realize Environmental purification function.

Embodiment 3

[0029] Pre-treat the surface of the glass ornament, remove the oil stains and dust on the surface, firstly apply the nano-Ca2 MgSi 2 o 7 : Eu, Dy light-storing material (light emission wavelength is about 545nm, afterglow time up to 20h); the coating solution obtained after mixing with a preset solvent, and then uniformly coated on the surface of the substrate by dipping process at a temperature of 200 ° C Process to obtain the light storage film layer, the thickness of the film layer is 200 microns; finally, the visible light responsive nano-TiO that matches the light storage film layer 2 2 The base photocatalytic spraying agent is sprayed onto the surface of the light storage film layer 2, and heat-treated at 200°C to obtain the photocatalytic purification film layer 3 with a film thickness of 50 microns, so that the glass decoration can achieve all-weather Environmental purification function.

Abstract

The invention discloses a preparation technology of a novel, safe and long-acting air-purification ornament. The material of the air purification ornament mainly comprises a base material, a light storage film layer and a photocatalytic purification layer, wherein under the condition of light illumination, the photocatalytic purification layer can be used for continuously catalyzing, decomposing and removing indoor toxic and harmful air, killing all kinds of planktonic bacteria and viruses and purifying the air in all directions; and the light storage film layer can be used for continuously absorbing light energy and converting the light energy into chemical energy for storage, and the stored light energy can be released in the night or under a light-free condition to provide light source for the photocatalytic purification layer, and therefore the photocatalytic purification layer can keep the photocatalytic activity continuously, and the air purification, antibiosis and deodorization can be achieved all day. According to the material of the air purification ornament, not only the function of beautifying the environment by a traditional ornament can be achieved, meanwhile, the indoor environment can be continuously purified all day to improve the air quality, but also the surface self-cleaning function of the photocatalytic purification layer can be utilized to improve the surface cleaning and beauty degree of the ornament; and the air-purification ornament has a good application prospect.

Description

technical field [0001] The invention relates to the field of functional decorations, in particular to a decoration capable of long-term sterilization and air purification. Background technique [0002] With the continuous increase of the new generation of highly educated consumer groups, there is a higher level of pursuit for the fashion and quality of interior decoration design. However, due to the use of poor-quality decorative materials, the toxic and harmful substances in many households and public places exceed the standard, making people feel uncomfortable and causing diseases. [0003] Indoor decorations have the advantages of elegant appearance and various shapes, which play a role in enhancing the indoor atmosphere, style and taste, and become an indispensable element in home decoration and venue layout. Indoor decorations have ornamental value, but their functions are single. The glue and plastic used for decoration and splicing of some decorations will even relea...
