Abstract

The invention relates to the technical field of aldehyde removal, and specifically discloses a high-temperature-resistant photocatalysis sustained-release type aldehyde-removing odor-removing paste, which is prepared from the following raw materials in percentage by weight: 90-97% of deionized water, 1-4% of L-shaped carrageenan, 0.1-0.6% of locust bean gum, 0.1-0.3% of calcium chloride, 0.5-1.5%of potassium chloride, 0.3-1.5% of a preservative, 0.5-1.5% of essence, 0.5-1.5% of ethanol, 1-6% of zinc ricinoleate and 0.03-0.6% of nano titanium dioxide. The invention further discloses a preparation method of the high-temperature-resistant photocatalytic sustained-release type aldehyde-removing odor-removing paste. The aldehyde-removing odor-removing paste has high temperature resistance, good toughness and no friability, and further has the effects of high-efficiency adsorption, continuous decomposition of formaldehyde and air purification.

Description

technical field [0001] The invention relates to the technical field of aldehyde removal, in particular to a high-temperature-resistant photocatalytic sustained release type aldehyde-removing and odor-removing paste and a preparation method thereof. Background technique [0002] Indoor air quality is a matter of great concern now. The quality of indoor air directly affects people's health and even life safety. However, there are usually residual formaldehyde in newly renovated buildings. Formaldehyde, as a chemical substance, can cause allergies. It can also induce cancer, which poses a huge threat to people's health. [0003] In the Chinese patent application publication number CN 108978929 A, an environmentally friendly wall with the function of removing aldehyde and deodorizing and its preparation method are disclosed, which specifically belong to the field of environmental protection decoration, including wall matrix and putty powder; the wall matrix includes A support l...
