specific Embodiment approach 1

[0014] Specific embodiment one: the special antibacterial paint of this embodiment hospital is by mass parts by the deionized water of 20~100 parts, the hydroxyethyl cellulose of 1~8 parts, the dispersant of 1~8 parts, the dispersant of 1~6 parts Wetting agent, 1-4 parts of antifungal agent, 1-8 parts of pH regulator, 1-6 parts of defoamer, 5-20 parts of antifreeze, 80-250 parts of titanium dioxide or precipitated barium sulfate , 130-470 parts of inorganic antibacterial materials, 1-6 parts of rheology modifiers, 48-100 parts of kaolin, 50-100 parts of light calcium powder, 5-20 parts of film-forming aids, 150-350 parts 1 part of acrylic emulsion and 2 to 8 parts of alkali-swellable thickener; wherein the inorganic antibacterial material is one or more of nano-silver solution, nano-zinc oxide, and nano-titanium dioxide, and the concentration of the nano-silver solution is 500 ~10000ppm, the particle size of nano-silver is 2-20nm; the particle size of nano-zinc oxide is 5-30nm...

specific Embodiment approach 2

[0030] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the hospital-specific antibacterial paint consists of 30 to 90 parts of deionized water, 2 to 7 parts of hydroxyethyl cellulose, and 2 to 7 parts of Dispersant, 2-5 parts of wetting agent, 2-3 parts of anti-mold agent, 2-7 parts of pH regulator, 2-5 parts of defoamer, 8-18 parts of antifreeze, 100-210 Parts of titanium dioxide or precipitated barium sulfate, 150-450 parts of inorganic antibacterial materials, 2-5 parts of rheology modifiers, 50-90 parts of kaolin, 60-90 parts of light calcium powder, 8-18 parts of It is made of film-forming aid, 180-320 parts of acrylic emulsion and 3-7 parts of alkali-swellable thickener. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0031] Specific embodiment three: what this embodiment is different from specific embodiment one is that the special antibacterial paint of the hospital is by mass fraction by the deionized water of 50 parts, the hydroxyethyl cellulose of 4 parts, the dispersant of 4 parts, the dispersant of 3 parts Wetting agent, 3 parts of antifungal agent, 3 parts of pH regulator, 3 parts of defoamer, 10 parts of antifreeze, 120 parts of titanium dioxide or precipitated barium sulfate, 200 parts of inorganic antibacterial material, 3 parts It is made of rheology modifier, 70 parts of kaolin, 70 parts of light calcium powder, 10 parts of coalescent, 200 parts of acrylic emulsion and 4 parts of alkali swelling thickener. Others are the same as in the first embodiment.

Abstract

The invention provides a preparation method of a special antibacterial paint for a hospital and relates to the preparation method of the antibacterial paint. The antibacterial paint is prepared from deionized water, hydroxyethyl cellulose, dispersing agents, wetting agents, mould inhibitors, pH regulators, defoaming agents, anti-freezing agents, titanium dioxide or precipitated barium sulphate, inorganic antibacterial materials, rheology modifying agents, kaolin, light calcium powder, film forming auxiliary agents, acrylic emulsion and alkali swelling thickening agents. The method comprises the following steps of: weighing raw materials; mixing and stirring the deionized water, the defoaming agents, the dispersing agents and the hydroxyethyl cellulose; adding the wetting agents, the mould inhibitors, the anti-freezing agents, the titanium dioxide or the precipitated barium sulphate, the rheology modifying agents, the kaolin, the light calcium powder and the alkali swelling thickening agents to be continuously stirred; then, adding the inorganic antibacterial materials, the acrylic emulsion and the pH regulators; stirring the materials; next, adding the film forming auxiliary agents; obtaining pulp after the stirring; and grinding the pulp to obtain the special antibacterial paint. The special antibacterial paint for the hospital has the excellent bloodstain resistance and contamination resistance performance, the advantages of strong-effect antibacterial and mould inhibition effects, environment friendliness and the like are also realized, the antibacterial performance is high, and the durability is good.

Description

technical field [0001] The invention relates to an antibacterial paint and a preparation method thereof. Background technique [0002] Due to the rapid economic development, especially in recent years, people pay more and more attention to their health, and the number of people going to the hospital for medical treatment is also increasing. Every time we go to the hospital, we will find that the frequent and complicated flow of personnel in the hospital environment and the high population density lead to serious infection in the hospital. Therefore, the sterilization and pollution resistance in the hospital environment are particularly important. [0003] Hospitals are space areas that are susceptible to cross-infection, so it is necessary to maintain the cleanliness of the air in the hospital. Most of the coatings used for painting cannot achieve the desired effect due to poor functional durability. Therefore, it is urgent to develop a hospital-specific antibacterial paint...
