Introduction to water-based nano antibacterial and mildew-proof coatings

Water-based nano antibacterial and mildew-proof coatings are simply called antibacterial coatings. They are coatings with antibacterial properties. This type of building coating is mainly characterized by its good mildew-proof performance and excellent decorative properties.

With increasing emphasis on health, people are paying more attention to their living environment. Surveys on microbial contamination in residential environments show that microbial pollution cannot be ignored. Applying water-based nano antibacterial and mildew-proof coatings directly to various materials can achieve antibacterial effects. It is also convenient to use. The development of this type of coating is one of the current directions of the paint industry.

These coatings use antibacterial agents with natural antibacterial effects and can be divided into inorganic and organic antibacterial coatings. Water-based nano antibacterial and mildew-proof coatings are particularly noteworthy. Due to their surface effects, their antibacterial ability is more than 200 times that of micron-level silver particles. Their antibacterial performance far exceeds that of traditional bactericides, with excellent results. In recent years, the development of water-based nano antibacterial and mildew-proof coatings has been rapid, and antibacterial methods are diverse. According to their reaction conditions, they can be divided into light irradiation, reductant reduction, radiation, and electrode electrolysis, etc.

With increasingly stringent control of volatile organic compounds (VOCs) in the coatings industry, water-based nano antibacterial and mildew-proof coatings have been vigorously developed, and the trend towards water-based coatings has become more pronounced. If harmful microorganisms are present on the coating surface and come into contact with the human body, various diseases can be transmitted, threatening human health. Therefore, adding a small amount of nanosilver powder to the coating to give it antibacterial properties is practical. Using a high-performance water-based fluorocarbon emulsion, with nanosilver powder as the antibacterial material, and adding wetting agents, dispersants, thickeners, and defoamers, an environmentally friendly nanosilver/fluorocarbon antibacterial coating can be prepared.

The main characteristics of water-based nano antibacterial and mildew-proof coatings are that they have both good mildew-proof performance and good decorative properties. After applying mildew-proof coatings to the surfaces of buildings in environments where mold easily grows, the buildings are less prone to mildew. Because building mildew-proof coatings are used for the interior and exterior walls, ceilings, or floors of buildings, they must also have good decorative effects. This is usually achieved by adding a mildew control agent to the coating.

After reading the above content, I believe that the readers present have understood the advantages and related content of water-based nano antibacterial and mildew-proof coatings. I hope this article will be helpful to everyone.
