Abstract
This invention relates to the field of glass coating technology, specifically to a self-cleaning coating for glass surfaces and its preparation method. The self-cleaning coating comprises the following components by weight: 3-7 parts of KH570-SiO₂ / photochromic microcapsules, 2-4 parts of fluoroalkylated silica, 25-35 parts of modified waterborne fluoroalkylsiloxane, 35-50 parts of deionized water, 0.5-2 parts of additives, 0.1-0.3 parts of leveling agent, and 0.2-0.3 parts of UV absorber; the additives are a combination of dispersant and thickener in a mass ratio of (70-85):(15-30). The core material of the photochromic microcapsules is a spiropyran compound, and the wall material is melamine-formaldehyde resin. It not only achieves self-cleaning but also provides anti-glare properties, making it widely applicable.
