Silicon dioxide sol-gel coating, preparation method and product

The preparation method comprises the following steps: uniformly mixing tetraethyl silicate, saturated fatty alcohol, a dispersing agent and water according to a ratio, regulating the pH value to 9-11 by using a pH regulator, and meanwhile, stirring and reacting at 20-60 DEG C for 15-45 minutes to obtain a mixed solution; carrying out first-stage microwave treatment on the mixed solution, and cooling to obtain an intermediate solution; and uniformly mixing the intermediate solution with fluorosilane and glucomannan, carrying out two-stage microwave treatment, cooling, and removing the pH regulator to obtain the silicon dioxide sol-gel coating. The silicon dioxide sol-gel coating disclosed by the invention is coated on the surface of a base material and then cured to form a coating, so that the coating not only has ultra-low reflectivity and ultra-high transmittance, but also has good corrosion resistance and shows multifunctionality. 本发明涉及一种二氧化硅溶胶凝胶涂料、制备方法及制品，按配比将硅酸四乙酯、饱和脂肪醇、分散剂和水混合均匀，用pH调节剂调节pH值至9-11，同时，于20-6
