Embodiment 1

[0041] refer to figure 2 , which is a single-atom antibacterial, antiviral, and aldehyde-removing paint additive suitable for interior wall paint disclosed in this application, consists of a carrier and a transition metal. The carrier is made of nano TiO 2 , nano-SiO 2 Porous composite carrier prepared with kaolin at a mass ratio of 40:40:20.

[0042] The transition metals are Ag, Zn, Cu and Mn, and the molar ratio of the transition metals Ag:Zn:Cu:Mn is 0.5:1:1:1. The transition metal is mixed with ammonia water to form a metal coordination precursor, which is then mixed with the carrier and calcined evenly. The metal coordination precursor is thermally decomposed on the carrier in situ, and the transition metal is wrapped by the carrier in the form of a single atom and evenly distributed on the carrier and channel surface.

[0043] A method for preparing a single-atom antibacterial, antiviral, and aldehyde-removing paint additive suitable for interior wall coatings, com...

Embodiment 2

[0050] The difference between Example 2 and Example 1 is that the mass ratio of the transition metal to the carrier is 1:150.

Embodiment 3

[0052] The difference between Example 3 and Example 1 is that the mass ratio of the transition metal to the carrier is 1:200.

Abstract

The invention relates to the technical field of interior wall coating fillers, in particular to a monatomic antibacterial antiviral formaldehyde-removing coating additive suitable for an interior wall coating and a preparation method of the monatomic antibacterial antiviral formaldehyde-removing coating additive. The monatomic antibacterial antiviral formaldehyde-removing coating additive suitable for the interior wall coating is composed of a carrier and transition metal, wherein the carrier is a complex of special fillers for various coatings; and the transition metal is uniformly distributed on the surfaces of the carrier and pore channels in a monatomic form. The coating additive has the advantages of excellent stability and compatibility, does not destroy the structure of the coating after being added into the coating, has rich monatomic active sites, can efficiently activate oxygen molecules in space, generate active oxygen species, oxidize cell membranes of bacteria, proteins and virus genetic materials and directly destroy a biological structure, and enables the coating to have antibacterial and antiviral effects; and meanwhile, the coating additive also has a rich specific surface area, can adsorb and lock formaldehyde small molecules, and is decomposed into carbon dioxide and water by oxidation seeds, so the coating is allowed to have an aldehyde removal effect.

Description

technical field [0001] The present application relates to the technical field of fillers for interior wall coatings, in particular to a single-atom antibacterial, antiviral, and aldehyde-removing coating additive suitable for interior wall coatings and a preparation method thereof. Background technique [0002] With the development of the economy and the change of people's consumption concept, people pay more and more attention to indoor health and safety, and put forward new requirements for interior wall coatings. The safety of interior wall coatings is closely related to people's healthy life. The harm of bacteria, viruses, formaldehyde and other pollutants in interior wall coatings has attracted people's attention, making functional coatings with antibacterial, anti-virus and aldehyde removal become the new mainstream. [0003] At present, major brand paint manufacturers in the market have launched various antibacterial, mildew-proof, formaldehyde-removing paints accordi...
