Problems solved by technology

However, it has been reported that photocatalytic particles often degrade the coating itself while photocatalytically degrading organic pollutants in the air, resulting in obvious aging phenomenon of the coating; on the other hand, adding adsorption particles and photocatalytic Particles, often due to the adsorption saturation of adsorptive particles and photocatalytic particles and the limit of photocatalytic degradation, the air purification effect is not obvious

Abstract

The invention relates to a preparing method of indoor peculiar-smell-removing environmental-friendly coating, and belongs to the technical field of energy conservation and environment protection. The coating comprises SiO2 aerogel particles and TiO2 particles, wherein the mass of the SiO2 aerogel particles is 1-10% of the total mass of the coating, and the mass of the TiO2 particles is 1-10% of the total mass of the coating. Experiment testing results of adsorption / photocatalytic degradation of formaldehyde show that: when the coating comprises 2.5-5.0% of high-adsorptivity particles with photocatalytic activity, and after adsorption / photocatalytic degradation is performed for 5-6 h, the formaldehyde concentration in the system decreases from 0.39 mg / m3 to final 0.04-0.05 mg / m3, and the adsorption / photocatalytic degradation rate reaches 79.49-89.74%.

Description

technical field [0001] The invention relates to a method for preparing an indoor odor-removing environmental protection coating, and belongs to the technical field of energy saving and environmental protection. Background technique [0002] With the improvement of people's living standards and the extensive use of building decoration materials, more and more people pay more and more attention to the health problems of the indoor air environment on the human body. Therefore, environmentally friendly functional architectural coatings are also receiving more and more attention. At present, most of the air purification coatings are made of TiO in coatings. 2 The photocatalytic degradation of photocatalytically active particles or the effect of negative ions or the use of adsorbents such as diatomaceous earth to achieve the effect of air purification. However, it has been reported that photocatalytic particles often degrade the coating itself while photocatalytically degrading o...
