Problems solved by technology

Because chitosan can only be dissolved in some dilute inorganic acids or organic acids, it cannot be directly dissolved in water, which limits its application to a large extent. Therefore, chitosan can be modified to be water-soluble by modification. Chitosan, but still retains its superior properties

Abstract

The invention relates to the technical field of environment friendly material air cleaning, and particularly discloses a photocatalyst air cleaning agent and a preparing method thereof. The photocatalyst air cleaning agent comprises, by weight, 1-5% of nanometer titanium dioxide, 0.6-1% of a dispersant, 0.3-0.7% of a defoamer, 2-5% of water-soluble chitosan and 88-96% of deionized water. The product can decompose and react under visible light, can effectively prevent harms caused by formaldehyde release after decoration to human body health, and has double sterilizing and antibacterial functions.

Description

Technical field [0001] The invention relates to the technical field of environmental protection material air purification, in particular to a photocatalyst air purification agent and a preparation method thereof. Background technique [0002] With the continuous improvement of people's health awareness, people have higher and higher requirements for the living environment, especially the living environment and the car interior environment. After the decoration of the living environment or the purchase of new furniture, it is easy to emit harmful gases such as formaldehyde, benzene, amines, TVOC, etc., which directly endanger people's health. Therefore, the management of the internal environment after the house decoration is very important. [0003] Photocatalyst is a nano-scale metal oxide material (titanium dioxide is more commonly used). It is coated on the surface of the substrate and dried to form a thin film. Under the action of visible light, it produces a strong catalytic d...
