Abstract

The invention discloses an indoor formaldehyde scavenger and a preparation method thereof, and relates to the field of indoor air purification. The formaldehyde scavenger is a light white transparentemulsion prepared from amino acids, a polyamine compound, titanium dioxide@carbon nitride quantum dots, a water-based polymer emulsion, a wood penetrant, a moisture absorbent, a surfactant, a lemon extract liquid and water. According to the invention, formaldehyde can be efficiently and durably immobilized through the amino acids and the polyamine compound to form a product which is good in stability, nontoxic and harmless; the formaldehyde is degraded through photocatalysis by the titanium dioxide@carbon nitride quantum dots, indoor formaldehyde can be thoroughly catalyzed and decomposed under common indoor conditions, the formaldehyde storage amount is reduced, meanwhile, the activity of viruses and bacteria can be effectively inhibited, and the effects of air purification, sterilization, deodorization, mildew prevention and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of indoor air purifiers, in particular to an indoor formaldehyde scavenger and a preparation method thereof. Background technique [0002] Modern people spend more than 80% of their time indoors every day. At the same time, with the development of my country's economy, people have higher and higher requirements for interior decoration, and problems with various decoration materials emerge one after another. For our country, it is an indisputable fact that the demand for logs is large and forest resources are scarce. Artificial panels solve this problem very well, and artificial panels account for a large proportion of decoration materials, but materials such as urea-formaldehyde resin and phenolic resin cannot be avoided in the production of artificial panels. Or under the situation of encountering tides, it is very easy to release a large amount of polluting gases such as formaldehyde, which seriously affe...
