Embodiment 1

[0074] Embodiment 1: Nano mildew-proof and moisture-proof material

[0075]

[0076]

Embodiment 2

[0077] Embodiment 2: Preparation method 1 of nano mildew-proof and moisture-proof material

[0078] The first step is the extraction of nano-mold and moisture-proof basic materials:

[0079] 1) Centrifuge dipotassium hydrogen phosphate, ammonium nickel sulfate, and sodium hydroxide in a high-speed accumulator, keep the temperature at 95°C for 15 minutes, and pH=7.9;

[0080] 2) Add silver nitrate, lower the temperature to 24°C and keep it for 80 minutes;

[0081] 3) Add nano-zinc, nano-silver and nano-nickel, mix and stir to form a translucent liquid; this is the basic material of the antifungal agent.

[0082] The second step is the organic synthesis of nano-mold and moisture-proof finished products:

[0083] 1) Centrifuge the prepared translucent liquid, keep the temperature at 120°C, pH=8.2, and keep it for 35 minutes;

[0084] 2) After cooling, add a titanium dioxide photocatalyst and heat it with a warm fire to form a translucent liquid;

[0085] 3) Spray the drug on ...

[0087] Embodiment 3: Preparation method 2 of nano mildew-proof and moisture-proof material

[0088] The first step is the extraction of nano-mold and moisture-proof basic materials:

[0089] 1) Centrifuge dipotassium hydrogen phosphate, ammonium nickel sulfate, and sodium hydroxide in a high-speed accumulator, keep the temperature at 90°C for 30 minutes, and pH=8.0;

[0090] 2) Add silver nitrate, lower the temperature to 23°C, and keep it for 70 minutes;

[0091] 3) Add nano-zinc, nano-silver and nano-nickel, mix and stir to form a translucent liquid; this is the basic material of the antifungal agent.

[0092] The second step is the organic synthesis of nano-mold and moisture-proof finished products:

[0093] 1) Centrifuge the prepared translucent liquid, keep the temperature at 130°C, pH=8.7, and keep it for 30 minutes;

[0094] 2) After cooling, add a titanium dioxide photocatalyst and heat it with a warm fire to form a translucent liquid;

[0095] 3) Spray the drug on...

Abstract

The invention relates to a mildew-proof and damp-proof nanomaterial. The nanomaterial is characterized in that: a pharmaceutical composition of the mildew-proof and damp-proof nanomaterial is placed in a fine pored silica gel, and a ratio of the pharmaceutical composition to the fine pored silica gel is 50-100 ml / kg. The mildew-proof and damp-proof nanomaterial comprises the follow compositions, by weight, 250-500 parts of silicon dioxide, 120-200 parts of nano-zinc, 130-170 parts of titanium dioxide photocatalyst, 100-150 parts of nano-silver, 100-150 parts of nano-nickel, 90-120 parts of dipotassium hydrogen phosphate, 80-120 parts of ammonium nickelous sulphate and 10-30 parts of sodium hydroxide. The mildew-proof and damp-proof nanomaterial can effectively inhibit and control bacteria genus, and has advantages of innocuity, odorlessness and prolonged action. Meanwhile, the mildew-proof and damp-proof nanomaterial is provided for purifying storage circumstance and improving health levels of staffs.

Description

technical field [0001] The invention is mainly aimed at the inhibition and prevention of storage mold, especially for the preparation method of a mold-proof and moisture-proof material loaded with nano-materials on silicon dioxide, and discloses a novel mildew-proof and moisture-proof material for mold prevention and control. Background technique [0002] Nano antibacterial materials are a new type of functional materials with antibacterial and bactericidal properties. In the chemical, chemical and pharmaceutical fields, some materials have bactericidal and bacteriostatic properties, such as some inorganic metal particles, organic substances, natural minerals and natural products. But more often, one or several specific antibacterial components (antibacterial agents) are added or compounded in common materials to make antibacterial materials. Such as antibacterial plastics, antibacterial synthetic fibers, antibacterial ceramics, etc. The advantages of inorganic antibacteria...
