Problems solved by technology

However, as the use time increases, impurities such as dust particles and harmful substances such as bacteria will adhere to the outer surface, but it is difficult to detect; and because the metal enclosure and the ceiling are generally suspended high, cleaning is extremely troublesome, so the existing Metal enclosures are seldom cleaned on a regular basis; as the usage time increases, the surface of the metal enclosures is prone to fogging and darkening, which affects the aesthetics of the product
The applicant once used nanoscale titanium dioxide in the coating of metal fence and ceiling, which solved the self-cleaning and bactericidal problems of metal fence and ceiling preferably, but because the titanium dioxide which plays a bactericidal effect must be in the The photocatalyst effect of sterilization can only be exerted when there is visible light or ultraviolet light, so it cannot fully exert the effect of sterilization at night, cloudy days and other times and occasions

Embodiment 1

[0020] The coating with long-term bactericidal function of the present embodiment comprises the following components in weight percentage: 5% of nano-zinc, said nano-zinc is nano-scale zinc oxide, 10% of nano-scale titanium dioxide, 20% of resin, 1% of nano-silver, and the rest for water. Nano-silver itself has a bactericidal effect, and it can also be used as a colorant. After being coated on metal enclosures and ceilings, it can have color and decorative properties, and the paint can no longer add colorants. This paint can be used as a paint alone for brushing or spraying, or it can be mixed into paint as an additive, and it can also be directly applied to indoor and outdoor tiles, tiles, wallpaper surfaces, paint surfaces and other substrate materials to achieve long-lasting effect All-weather sterilization and self-cleaning effect.

[0021] The preparation method of the coating with long-acting bactericidal function of the present embodiment, comprises the following steps...

Embodiment 2

[0026] The coating with long-term bactericidal function of the present embodiment comprises the following components in weight percentage: 20% of nano-zinc, said nano-zinc is nano-scale zinc oxide, 1% of nano-scale titanium dioxide, 5% of resin, 1% of nano-copper, and the rest for water. Nano-copper is used as a colorant, which can have the color of copper after being applied to the metal enclosure and ceiling, and is decorative, and the paint does not need to add colorants. This paint can be used as a paint alone for brushing or spraying, or it can be mixed into paint as an additive, and it can also be directly applied to indoor and outdoor tiles, tiles, wallpaper surfaces, paint surfaces and other substrate materials to achieve long-lasting effect All-weather sterilization and self-cleaning effect.

[0027] The preparation method of the coating with long-acting bactericidal function of the present embodiment, comprises the following steps:

[0028] (1) mixing and stirring ...

Embodiment 3

[0032] The coating with long-term bactericidal function of this embodiment includes the following components in weight percentage: 15% of nano-zinc, which is nano-sized zinc oxide, 2% of nano-sized titanium dioxide, 10% of resin, and the rest is water. This paint can be used as a paint alone for brushing or spraying, or it can be mixed into paint as an additive, and it can also be directly applied to indoor and outdoor tiles, tiles, wallpaper surfaces, paint surfaces and other substrate materials to achieve long-lasting effect All-weather sterilization and self-cleaning effect.

[0033] The preparation method of the coating with long-acting bactericidal function of the present embodiment, comprises the following steps:

Abstract

The invention discloses a paint which can perform sterilization and purification without light time and has a long-acting sterilization function and a preparation method thereof. The paint can be directly applied to a metal shield plate, a ceiling and various substrate materials, is environment-friendly, sanitary, beautiful and durable, and is convenient to wash. The paint having the long-acting sterilization function comprises the following components by weight percent: 5-20% of nano zinc, 1-10% of nano titanium dioxide, 5-20% of resin and the balance of water. The preparation method of the paint having the long-acting sterilization function comprises the following steps of: (1) mixing and stirring nano zinc, nano titanium dioxide and the resin with water based on the weight proportion; (2) heating slurry at the temperature of 40-80 DEG C and further evenly stirring, and controlling the pH value of the slurry to 1-2 in the heating and stirring process; and (3) inspecting and packaging. The paint can be widely applied to the field of building materials.

Description

technical field [0001] The invention relates to a paint with long-term bactericidal function and a preparation method thereof. Background technique [0002] With the development of science and technology, various modern buildings are displayed in front of people, such as glass walls, metal packaging and so on. At present, many new buildings adopt metal structure roofing systems, especially steel structure buildings, and their roofing systems naturally also adopt metal structure roofing systems. Composite metal roofing systems are more and more widely used in various industries, sports, entertainment, exhibition halls, retail supermarkets and other buildings. Metal roofing systems require the use of metal roof panels and metal structural base plates. Additionally, metal wall panels are now commonly used in various building systems. Coated metal panels used for wall or roof enclosures, including the above-mentioned metal roof panels, metal structural bottom panels and metal...
