Embodiment 1

[0046] A kind of multi-ion antibacterial metal coating is made by following method:

[0047] (A) preparation of acrylic resin emulsion:

[0048] Weigh butyl acrylate, methyl acrylate, acrylonitrile, and acrylic acid monomers according to the mass ratio of 75:25:1:1 and mix them uniformly to obtain mixed monomers for later use; take acrylamide and toluene with a mass ratio of 1:1 Mix and stir, heat with a water bath at 40°C, and control the internal temperature of the solution to not be higher than 30°C. After the acrylic amine is completely dissolved, an aqueous solution of the crosslinking agent is obtained for use; the ammonium sulfate is dissolved in water 5 times its mass to obtain sulfuric acid Ammonium solution, spare.

[0049] Add 55g of distilled water and 165g of sodium lauryl sulfate into the reaction kettle, stir to dissolve, turn on the cooling water of the reflux condenser, and heat the kettle with steam. After the temperature in the kettle is stabilized at 80°C,...

Embodiment 2

[0059] A kind of multi-ion antibacterial metal coating is made by following method:

[0060] (A) preparation of acrylic resin emulsion:

[0061] Weigh butyl acrylate, methyl acrylate, acrylonitrile, and acrylic acid monomers according to the mass ratio of 70:30:0.5:0.5 and mix them evenly to obtain mixed monomers for later use; take acrylamide and toluene with a mass ratio of 1:0.5 Mix and stir, heat with a water bath at 45°C, and control the internal temperature of the solution to not be higher than 30°C. After the acrylic amine is completely dissolved, an aqueous solution of the crosslinking agent is obtained for use; the ammonium sulfate is dissolved in water four times its mass to obtain sulfuric acid Ammonium solution, spare.

[0062] Add 10g of distilled water and 100g of sodium lauryl sulfate into the reaction kettle, stir to dissolve, turn on the cooling water of the reflux condenser, and heat the kettle with steam. After the temperature in the kettle is stabilized at...

Embodiment 3

[0072] A kind of multi-ion antibacterial metal coating is made by following method:

[0073] (A) preparation of acrylic resin emulsion:

[0074] According to the mass ratio of 80:20:1.5:1.5, respectively weigh butyl acrylate, methyl acrylate, acrylonitrile, and acrylic acid monomers and mix them uniformly to obtain mixed monomers for later use; take acrylamide and toluene with a mass ratio of 1:1.5 Mix and stir, heat with a water bath at 45°C, and control the internal temperature of the solution to not be higher than 30°C. After the acrylic amine is completely dissolved, an aqueous solution of the crosslinking agent is obtained for use; the ammonium sulfate is dissolved in water six times its mass to obtain sulfuric acid Ammonium solution, spare.

[0075] Add 100g of distilled water and 300g of sodium lauryl sulfate into the reaction kettle, stir to dissolve, turn on the cooling water of the reflux condenser, and heat the kettle with steam. After the temperature in the kettle...

Abstract

The invention relates to the field of a coating and discloses a multi-element ion anti-microbial metallic coating. A preparation method comprises the following steps: (A) preparing acrylic resin emulsion; (B) preparing nanometer silver sol; (3) preparing the coating: respectively weighing deionized water, de-foaming agents, propylene glycol, propylene glycol n-butyl ether and sodium n-octadecyl sulfonate, and mixing and stirring; adding titanium dioxide, talcum powder and calcium carbonate in a stirring process, uniformly stirring and then adding tributyl phosphate, and stirring for acquiring a sizing agent; and adding the acrylic resin emulsion, a multi-element ion anti-microbial material the nanometer silver sol into the sizing agent, and uniformly stirring for acquiring the coating. The multi-element ion anti-microbial metallic coating disclosed by the invention contains the multi-element ion anti-microbial material, utilizes an ion anti-microbial principle and a micro-magnet electric field technical principle, is high in stability and high in anti-microbial activity, has an adsorption capacity and is capable of effectively increasing the anti-microbial property of the coating and prolonging the service life of the coating.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a multi-ion antibacterial metal coating. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] At present, there are many kinds of coatings on the market, many of which have antibacterial function. For example, the Chinese invention patent with the application number CN201410015469.2 discloses an antibacterial diatomite-based coating and its preparation method and application. The invention uses the special pore structure of diatomite to load antibacterial agents and endows diatomite with antibacterial properties; The diatomite coating loaded with antibacterial agent, disper...
