Anti-fogging self-cleaning weakening ultraviolet glass coating and preparation method thereof

Abstract

The invention provides an anti-fogging self-cleaning weakening ultraviolet glass coating and a preparation method thereof. The coating is prepared from the following raw materials in percentage by mass: 0.1-1.5 parts of an emulsifier, 0.1-1.5 parts of polyving akohol, 0.2-1.3 parts of an anionic surfactant, 0.1-1.3 parts of a photocatalyst, 0.1-1 parts of sodium metasilicate, 1-15 parts of isopropanol, 3-8 parts of glycerin, 0.05-0.3 parts of essence, 30-50 parts of ethanol, and the balance of deionized water, wherein the emulsifier is octylphenol polyoxyethylene ether and octylphenyl polyoxyethylene ether; while preparing, the raw materials are mixed, and then a mixture is uniformly stirred. Compared with the prior art, the glass coating disclosed by the invention has strong photocatalytic activity and lasting fogging resistance, is capable of weakening ultraviolet light and has excellent self-cleaning ability and sterilization ability, and is easily prepared.

Description

technical field [0001] The invention belongs to the technical field of nano photocatalytic materials, and relates to an anti-fog self-cleaning and weakening ultraviolet glass coating and a preparation method thereof. Background technique [0002] There is water vapor in the air. When the water vapor with a certain partial pressure is cooled to its dew point, the water vapor will reach saturation, and small water droplets will be condensed. When the small water droplets adhere to the surface of the transparent substrate, atomization will occur. . Glass is a must-have in life. For example, glass is used as walls in buildings for the sake of beauty and brightness, windows of vehicles and other vehicles are made of glass, bathroom sliding doors, mirrors, etc. are also glass products. Glass is ubiquitous in life, but in cold winter or humid rainy season, the water vapor in the hot air in the cab or inside the car will condense into dewdrops on the cold glass surface, which reduc...

AI Technical Summary

Problems solved by technology

Glass is ubiquitous in life, but in cold winter or humid rainy season, the water vapor in the hot air in the cab or inside the car will condense into dewdrops on the cold glass surface, which reduces the light transmittance of the glass and affects the line of sight, greatly Increased the danger of driving; the mist generated on the glass of the building brings inconvenience to life, and at the same time increases additional cleaning costs

[0003] The anti-fog time of existing commercial anti-fog coatings is generally 2-7 days. The anti-fog time is short and requires frequent cleaning. At the same time, excessive ultraviolet rays will pass through under strong sunlight, causing serious damage to the skin.
