Nanometer is a familiar unit. Nanometer should be a small unit in everyone's concept, but it is invisible to the naked eye. Nano-coating is a new type of coating, which is now widely used in the home improvement market. Compared with traditional coatings, nano-coatings have many advantages, such as not easy to get dirty and simple construction. The use of nano-coating will not cause harm to human body. The following small series will introduce the price, advantages and market prospects of nano-coatings.
What is nano-coating?
Nano-paint adopts new nano-materials, and its performance is a long span in latex paint, which is greatly improved in scrub resistance, dirt resistance and alkali resistance compared with general latex paint. Nano-coating has the characteristics of non-toxicity, mildew resistance, scrubbing resistance, convenient construction and chemical corrosion resistance.
The price of nano-coatings
The market price of nano-coatings ranges from 27 yuan to 68 yuan. (Price source network, for reference only. )
What are nanotechnology and nano-coatings?
Nanometer (nm) is the smallest unit of measurement after centimeter and micron at present, and 1 nm is one millionth of a millimeter, that is, nanometer, that is, one billionth of a meter. Nanostructures usually refer to tiny structures with the size below 100 nm. Its ultimate goal is to construct products with specific functions through atoms and molecules. The wear resistance of some materials is 27 times that of brass and 7 times that of steel. Therefore, nanotechnology is a technology to make substances with single atoms and molecules. China has included nanotechnology in the national "863" high-tech plan, and successfully applied it in aviation, aerospace, coatings, clothing, watercolor, rubber and plastics, medicine, semiconductors, chemical industry and other fields. Since 200 1 was patented, nano-coatings have been successfully applied in more than 20 provinces and cities and dozens of manufacturers.
The application of nanotechnology is the symbol of world science and technology. The application and development of nanotechnology in coatings industry has promoted the upgrading of coatings and created a breakthrough new era in which coatings have become truly green products. Nano-coatings have been recognized as special products for the construction project of Beijing Olympic Village, which shows the application value of nano-coatings in the construction field. The water-based environmentally-friendly nano-coating I developed is waterproof, fireproof and mildew-proof, acid and alkali-resistant, non-toxic and tasteless, and has a fresh smell. It has passed the performance test of National Building Materials Testing Center and the limited sampling test of "non-toxic" (green) indoor substances, and it is a truly safe, healthy and environmentally friendly product. It uses unique photocatalytic technology to decompose and eliminate toxic gases in the air. It can absorb and eliminate harmful gases such as formaldehyde and ammonia, and make the indoor air fresher. After testing, the killing rate of various molds is over 99%. It has a long-term anti-mildew and anti-algae effect and is suitable for painting in families, hospitals, hotels and schools. Nano-exterior wall coating, using the double hydrophobic lotus leaf mechanism of nano-materials, has the characteristics of low surface tension, strong adhesion, high film hardness, good toughness, excellent self-cleaning function, strong adhesion to dust and dirt, excellent hydrophobicity and easy cleaning of dirt. The washability is more than 10000 times, with good light and color retention function and strong ultraviolet resistance. The service life is as long as 10- 15 years. The particle diameter is small, which can penetrate into the wall and react with silicate substances on the wall to make it firmly combined, with strong adhesion, no peeling and peeling, and anti-aging. Its nano-antifreezing functional coating not only has various excellent properties of nano-coating, but also can be applied normally in the range of-10℃ to -25℃, breaking the precedent that building coatings cannot be applied below 0℃, and nano-coating can be wet-coated, breaking the requirement of building coatings for wall humidity below 10%, shortening the construction period of the building industry, improving efficiency and efficiency. Therefore, it has been welcomed and praised by the construction unit.
What are the advantages of nano-coatings compared with ordinary latex paints?
As the nano-coating is made of a series of nano-materials, such as nano-monomer slurry, nano-emulsion, nano-color paste, nano-bactericide, nano-multifunctional additive, etc., compared with the raw materials used in the existing latex paint, the nano-coating has incomparable superfine and uniqueness, its comprehensive performance and quality are far superior to similar products, and its cost is lower than that of traditional products, and it has the following characteristics:
1. Using the double hydrophobic mechanism of nano-materials, the moisture in the coating can be effectively discharged, and the invasion of external moisture can be prevented, so that the coating has the performance of breathing.
2. Using the special function and small molecular structure of nano-materials, it reacts with inorganic silica and calcium in the wall, so that the wall and the coating film form a firm claw-like penetration, and the coating film will not fall off. No peeling, high hardness and washability.
3. Using the physical principle of nano-material super double interface, the invasion of dust and oil pollution can be effectively discharged, so that the wall has good self-cleaning function.
4. By using the photocatalytic technology of nano-materials, harmful gases in the air can be efficiently decomposed and eliminated, and the radiation of decomposed ultraviolet rays can be reduced, thus enhancing the anti-aging ability of the coating and making the coating have the performance of purifying the air.
5. Using the activation technology of nano-materials, the antibacterial coating formed by the coating can destroy the cell membranes of Escherichia coli and Staphylococcus aureus, thus effectively killing or inhibiting the reproduction of bacteria.
6. Unique environmental protection: normal temperature and pressure production, non-toxic, tasteless, pollution-free, water-soluble and environmentally friendly.
7. Strong adhesion: Strong adhesion to mortar, concrete, stone, asbestos board, wood, metal and other building materials.
8. Excellent high weather resistance: suitable for both high and low temperatures in the north and south. It can also be constructed on a wet base surface, and the frost-resistant type can be constructed at a low temperature of 0℃ to -25℃ without deterioration after storage.
9. Because the nano-powder material is very fine (close to the molecular structure) and difficult to disperse (always floating on the water), the researchers in our institute used foreign experience for reference to polymerize it into nano-slurry monomer, which makes the coating easy to disperse in production, can absorb and refract UVC ultraviolet rays, and its service life exceeds 10- 15 years.
10, spraying, brushing, rolling, painting and other conventional methods, each kilogram can be constructed 12- 14 square meters, and 6-8 square meters can be constructed twice.
The production adopts normal temperature and pressure, and there is no pollution from waste water, waste gas and waste residue.
The above small series introduces the market price of nano-coatings, the advantages of nano-coatings, and the advantages of nano-coatings compared with ordinary coatings. What I am most afraid of after decoration is the strong pungent smell. If you use nano-coatings, you won't have such troubles. However, the traditional coatings may fall off after being used for a long time. If you use nano-coatings, you won't have such troubles again. Nanocoatings have many advantages. Try it if you like.
