Problems solved by technology

[0005] It can be known from the mechanism of action of the photocatalyst agent that the photocatalyst catalyst can decompose formaldehyde only in contact with the air under the irradiation of ultraviolet light or natural light. However, there are two main methods of using the existing photocatalyst agent: (1) mixing In the adhesive, it is pasted between the decorative layer and the base layer of the board. In this way, the photocatalyst agent is difficult to contact with light and air, and it is difficult to decompose formaldehyde; (2) Use the adhesive component to coat the photocatalyst on the surface of the board, In this way, as time goes by, the adhesive component will decompose due to the oxidation of titanium oxide particles, lose its adhesiveness, and peel off from the surface of the base material. Therefore, the stability of the adhesive after coating is poor and cannot be stabilized. It exists on the surface of the board, so it cannot achieve the purpose of stably removing aldehydes

Abstract

The invention relates to the field of formaldehyde removal agents, and discloses an artificial board formaldehyde removal agent, which comprises the following components: modified nano TiO2 powder, activated carbon powder, carbon nanofibers, waterborne epoxy resin, a dispersing agent, an emulsifying agent, a defoaming agent, a film-forming assistant, a preservative and water. The modified nano TiO2 powder is Pt-X doped nano TiO2 powder, wherein X is a halogen element. After the formaldehyde removal agent is coated on the surface of a plate, a film can be formed more stably, photocatalyst substances are distributed more evenly, and the photocatalysis efficiency can be improved, therefore formaldehyde and other organic matters can be degraded more durably, stably and efficiently.

Description

technical field [0001] The invention relates to the field of aldehyde-removing agents, in particular to a wood-based panel aldehyde-removing agent and its preparation method and use method. Background technique [0002] With the development of society and the improvement of people's living standards, it has become a fashion trend to pursue a high-end and comfortable living and living environment for interior decoration. However, in the decoration process, it is inevitable to use a large number of composite man-made panels, resulting in a large amount of volatile organic compounds, mainly formaldehyde and benzene compounds, among which formaldehyde is the most representative and has the most significant impact on human health. . In addition, suspended particulate matter is also one of the important pollutants in indoor air. Suspended inhalable particulate matter can be used as a carrier of bacteria, viruses, heavy metals, inorganic gases and organic substances, and can enter...
