Problems solved by technology

Antibacterial agents can be divided into several categories: natural, organic, and inorganic; Among them, natural antibacterial agents are not conducive to large-scale use due to their high extraction costs; organic antibacterial agents have a short service life, and most of them have toxic side effects; The performance is good, but long-term use will cause the coating to change color; another type of antibacterial agent is an oxide antibacterial agent, which has strong antibacterial properties and high heat resistance, and is currently an ideal antibacterial agent; but oxide antibacterial agents Poor dispersion in water-based coatings, and such antibacterial agents will form strong oxidizing groups O2- on the surface to damage the coating, thereby affecting the service life of the coating

Embodiment 1

[0012] A method for preparing a water-based antibacterial coating containing polyolefin carbazine siloxane compound. At 20°C, 10 parts of water, 5 parts of ethanol and 1 part of diethylene glycol butyl ether (solvent) are mixed and dropped into the water, then add 1 part of polyolefin-based carbazine and 1 part of siloxane compound to the mixed water, and then drop 0.1 part of diethylene glycol monomethyl ether, 0.3 part of polyacrylate, organic silicon oxide into the mixed water 0.1 part of alkane defoamer, 0.1 part of hydroxyethyl cellulose, 0.1 part of polyurethane rheology modifier, 0.2 part of silicone oil, 0.2 part of polyether polyester modified organosiloxane, and 0.1 part of acrylate. 1.2 parts of water-based additives, and then add 40 parts of water-based fluorocarbon resin to the mixed water and stir for 1 hour to obtain a water-based antibacterial coating.

Embodiment 2

[0014] A method for preparing a water-based antibacterial coating containing polyolefin carbazine siloxane compound. At 40°C, 15 parts of water, 7 parts of ethanol and 3 parts of diethylene glycol butyl ether (solvent) are mixed and dropped into the water, then add 2 parts of polyolefin-based carbazine and 2 parts of siloxane compound to the mixed water, and then add 0.2 parts of diethylene glycol monomethyl ether, 0.3 parts of polyacrylate, organosiloxane 0.1 part of alkane defoamer, 0.1 part of hydroxyethyl cellulose, 0.2 part of polyurethane rheology modifier, 0.2 part of silicone oil, 0.2 part of polyether polyester modified organosiloxane, and 0.1 part of acrylate. 1.4 parts of water-based additives, and then add 50 parts of water-based fluorocarbon resin to the mixed water and stir for 1 hour to obtain a water-based antibacterial coating.

Embodiment 3

[0016] A method for preparing a water-based antibacterial coating containing polyolefin carbazine siloxane compound. At 60°C, 20 parts of water, 10 parts of ethanol and 5 parts of diethylene glycol butyl ether (solvent) are mixed and dropped into the water, then add 4 parts of polyolefin-based carbazine and 4 parts of siloxane compound to the mixed water, and then add 0.2 parts of diethylene glycol monomethyl ether, 0.3 parts of polyacrylate, organosiloxane 0.2 parts of alkane defoamer, 0.2 parts of hydroxyethyl cellulose, 0.2 parts of polyurethane rheology modifier, 0.2 parts of silicone oil, 0.2 parts of polyether polyester modified organosiloxane, and 0.1 part of acrylate ester. 1.6 parts of water-based additives, and then add 60 parts of water-based fluorocarbon resin to the mixed water and stir for 1.5 hours to obtain a water-based antibacterial coating.

Abstract

The invention relates to a water-based antibacterial coating which comprises water-based fluorocarbon resin, polyolefin-based carbamidine, a siloxane compound, a water-based assistant, water-based special melamine resin, an inert high-temperature environment-friendly weather-resistant pigment, diethylene glycol butyl ether (solvent), ethanol and water. The water-based antibacterial coating is prepared by adding water-based fluorocarbon resin and an environment-friendly high-temperature weather-resistant pigment into a polyolefin carboxazine siloxane compound serving as a main antibacterial substance. The coating is a single-component water-based antibacterial coating, has an antibacterial rate of 99.99%, good film adhesion, high hardness, good decorative effect, excellent weather resistance and the like, can be widely applied to the surfaces of aluminum profiles and curtain walls, has a good antibacterial effect and provides lasting protection performance.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, more specifically, relates to a water-based antibacterial coating. Background technique [0002] Antibacterial coatings refer to a class of coatings that add antibacterial agents to make them have antibacterial properties. Because they can kill molds and bacteria such as Escherichia coli and Staphylococcus, they can improve the indoor environment and protect people's health. Its research and Apps get a lot of attention. Antibacterial agents can be divided into several categories: natural, organic, and inorganic; Among them, natural antibacterial agents are not conducive to large-scale use due to their high extraction costs; organic antibacterial agents have a short service life, and most of them have toxic side effects; The performance is good, but long-term use will cause the coating to change color; another type of antibacterial agent is an oxide antibacterial agent, which has str...
