Multifunctional antibacterial coating

Abstract

The invention provides a multifunctional antibacterial coating. The multifunctional antibacterial coating disclosed by the invention adopts an antibacterial agent formed by compounding of nano-silver,nano-copper and nano-zinc, and also adopts an interior wall odorless emulsion, so the finished coating is very low in odor, friendly to environment and harmless to the human body. The antibacterial agent formed by compounding the nano-silver, the nano-copper and the nano-zinc can also play a good role in killing and inhibiting in a complex microbial environment; nanometer titanium dioxide and nanometer silicon dioxide can absorb natural light to decompose harmful organic matters and inorganic matters, absorb and decompose decoration pollution gas such as formaldehyde, and purify air; the antibacterial agent can destroy cell membranes of bacteria and protein carriers of coagulated viruses, so sterilization effect is achieved; and meanwhile, the antibacterial agent has inhibiting and killing functions on pathogenic bacteria such as escherichia coli, staphylococcus aureus, influenza A H1N1 and H3N2, klebsiella pneumoniae and pseudomonas aeruginosa, and also has the effects of resisting graffiti and absorbing and decomposing residual formaldehyde and VOC.

Description

technical field [0001] The invention belongs to the technical field of coating preparation, and in particular relates to a multifunctional antibacterial coating applied to interior wall decoration of buildings. Background technique [0002] The paint in the traditional technology is usually used as a wall decoration layer material, which simply plays the role of beautiful appearance; in recent years, public health crises have occurred frequently, and a large part of them are caused by pathogenic bacteria, and microorganisms are absent in nature. Everywhere, even the paint is no exception, especially the water-based paint, which provides a good growth environment for microorganisms. If the microorganisms are not stopped, the microorganisms will grow and reproduce on the surface of the coating and metabolize to produce various enzymes, acids and Secondary metabolites such as toxins erode the coating to varying degrees, causing the coating to fade, mold, grow algae, and even fa...

[0002] The paint in the traditional technology is usually used as a wall decoration layer material, which simply plays the role of beautiful appearance; in recent years, public health crises have occurred frequently, and a large part of them are caused by pathogenic bacteria, and microorganisms are absent in nature. Everywhere, even the paint is no exception, especially the water-based paint, which provides a good growth environment for microorganisms. If the microorganisms are not stopped, the microorganisms will grow and reproduce on the surface of the coating and metabolize to produce various enzymes, acids and Secondary metabolites such as toxins erode the coating to varying degrees, causing the coating to fade, mold, grow algae, and even fall off; in addition to corroding the coating film, pathogenic microorganisms can also spread to humans through contact. Health is a threat; therefore, the role of antibacterial coatings in the prior art has been extended from purely decorative to protecting buildings from microbial erosion, and even by inhibiting the excessive growth and reproduction of bacteria and viruses on the wall, the wall is prevented from becoming the spread of bacteria and viruses In order to protect the health of residents; although a variety of antibacterial coating technologies have been disclosed in the prior art, there are problems such as few types of antibacterial, low antibacterial rate, and single function
