Antibacterial and antiviral formaldehyde removal coating and preparation method thereof

Abstract

The invention discloses an antibacterial and antiviral aldehyde-removing coating and a preparation method thereof, the aldehyde-removing coating contains negative ion powder, negative oxygen ions generated in the negative ion powder have high activity and strong oxidation-reduction effect, and can destroy the activity of cell membranes or cell protoplast active enzymes of Sonogashira, so that the antibacterial and bactericidal purposes are achieved; meanwhile, irritant gases such as benzene, formaldehyde, ketone, ammonia and the like volatilized by decoration materials used in the indoor decoration process of indoor peculiar smell and various harmful gases and sour and foul smell of leftovers in daily life are eliminated; in addition, the barium sulfate is added, and the agglomerated titanium dioxide particles can be separated by mesoscopic microcrystal particles of the barium sulfate, wherein each barium sulfate particle has enough surface energy, 4-10 titanium dioxide particles can be adsorbed around the barium sulfate particle, spatial isolation is effectively achieved, and the scattering rate of each titanium dioxide particle reaches the maximum. Therefore, the nano inorganic formaldehyde removal resin is prepared, can rapidly absorb formaldehyde and has a good fireproof effect.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to an antibacterial and antiviral aldehyde-removing paint and a preparation method thereof. Background technique [0002] In recent years, with the development of my country's economy and the improvement of people's living standards, people's awareness of environmental protection and health requirements are increasing day by day, and the pollution caused by toxic and harmful substances in building decoration materials to the environment and the impact on human health have become increasingly prominent. Toxic and harmful substances mainly come from formaldehyde, ammonia and other pollutants released by building decoration materials; among them, formaldehyde mainly comes from plywood, joinery board, paint, coating and other decorative materials used for interior decoration. Dissolved irritating gas is relatively harmful to the human body. It can cause irritation to the eyes, s...

AI Technical Summary

Problems solved by technology

[0003] At present, both at home and abroad have done in-depth research on the purification of indoor environments, and developed a series of air purification products, such as negative ion generators, plasma additives, formaldehyde absorbents, etc. Formaldehyde absorbents such as activated carbon, although they can Absorb some formaldehyde, ammonia and other substances, but the absorption amount is very limited, and under certain conditions, the absorbed formaldehyde, ammonia and other substances will be released, causing secondary pollution;

[0004] And the existing antibacterial and antiviral coatings also need to add a large amount of additives while playing antibacterial and antiviral, and produce a large amount of harmful substances, such as some formaldehyde absorbers themselves are artificially synthesized chemicals, while removing formaldehyde themselves It will release other polluting gases, pollute the environment and cause harm to human health at the same time, and the existing aldehyde-removing coating has a low aldehyde-removing rate, and its own flame retardancy is poor, so it is impossible to achieve the bactericidal effect while removing formaldehyde;
