preparation example Construction

[0049] The present application also provides the preparation method of the above-mentioned bactericidal gray composite coating, including:

[0050] (1) Pre-treatment of the substrate: including polishing and cleaning;

[0051] (2) electroplating the high-sulfur nickel layer on the surface of the pretreated substrate;

[0052] Optionally, (3) wire drawing the high-sulfur nickel layer;

[0053] (4) Electroplating the gray composite bactericidal layer on the surface of the high-sulfur nickel layer obtained in step (2) or the high-sulfur nickel layer obtained in step (3) after wire drawing.

[0054] In the embodiments of the present application, the cleaning treatment in the pretreatment described in step (1) may include fine cleaning processes such as wax removal, oil removal, electrolysis, and pure water cleaning.

[0055] In the embodiment of the present application, the conditions for electroplating the high-sulfur nickel layer in step (2) may include: a temperature of 45-55...

Embodiment 1

[0064] (1) Pretreatment of electroplating

[0065] Polishing and fine cleaning (including wax removal, oil removal, electrolysis, pure water cleaning) of stainless steel substrates;

[0066] (2) Electroplating a high-sulfur nickel layer on the surface of the pre-treated substrate

[0067] The electroplating solution for forming the high-sulfur nickel layer includes: nickel sulfate with a concentration of 380g / L, nickel chloride with a concentration of 70g / L, boric acid with a concentration of 45g / L, and 90% of the high-sulfur nickel HAS with a concentration of 3mL / L;

[0068] The electroplating process conditions include: the temperature is 50°C, the voltage is 8V, and the cathode current density is 5A / dm 2 , the plating time is 1800s;

[0069] (3) Drawing the high-sulfur nickel layer

[0070] The process conditions of wire drawing include: the wire drawing wheel is a nylon wheel, the speed of the wire drawing machine is 350rpm, and the wire drawing time is 15s;

[0071] (...

Embodiment 2

[0075] The preparation method is basically the same as that of Example 1, except that in the electroplating solution used in the electroplating of the gray composite bactericidal layer in step (4), the concentration of cetyltrimethylammonium iodide is 100 g / L.

Abstract

The invention discloses a germicidal gray composite coating, a preparation method thereof and a gray germicidal product. The germicidal gray composite coating comprises a high-sulfur nickel layer and a gray composite germicidal layer, the high-sulfur nickel layer is arranged on a base material with a sterilization requirement; the gray composite sterilization layer is arranged on the surface of one side, far away from the base material, of the high-sulfur nickel layer; the gray composite bactericidal layer has a nanoneedle structure and is formed by a composite raw material containing bactericidal ammonium salt, and the concentration of the bactericidal ammonium salt in the composite raw material is 50-100g / L. The bactericidal gray composite coating and the gray bactericidal product can be directly prepared through an electroplating method, a good broad-spectrum bactericidal effect can be achieved without spraying an antibacterial material containing nano Ag < + > and Cu < 2 + >, and the bactericidal effect can be directly displayed.

Description

technical field [0001] The present application relates to, but is not limited to, the field of sterilization technology, and particularly refers to a sterilization gray composite coating, a preparation method thereof, and a gray sterilization product. Background technique [0002] Kitchen and bathroom products with sterilization function are more and more widely concerned by consumers. The sterilization materials used in the sterilization kitchen and bathroom products on the market mainly include inorganic sterilization materials (transition metal ions such as silver, copper, zinc, and their complexes, etc.), composite sterilization materials, and organic sterilization materials. Among them, inorganic bactericidal materials have the characteristics of high sterilization rate, good safety, no drug resistance, and good heat resistance stability. . The preparation methods of inorganic sterilizing materials and composite sterilizing materials containing inorganic sterilizing m...
