Problems solved by technology

Coating anti-reflection coating on the surface of photovoltaic glass has almost become the standard configuration of the industry. Solar photovoltaic panels are mainly installed in outdoor environments, which are inevitably affected by environmental conditions such as wind, sand, rain, and fog. Due to the differences in domestic natural environments, Sometimes sand, dust, pollutants, etc. adhere to the glass surface, requiring high frequency of glass cleaning, which increases the cost of maintenance

Abstract

The invention relates to the technical field of glass product manufacturing, in particular to a hydrophobic anti-reflection solution and hydrophobic anti-reflection glass. The hydrophobic anti-reflection solution provided by the invention is prepared by the following steps: 1, preparing a base-catalyzed nano-SiO2 sol; 2, preparing a hydrophobically modified solution; 3, stirring the hydrophobically modifying solution and the base-catalyzed nano-SiO2 sol, sequentially adding a monomeric nanosilver solution, a stabilizer, a leveling agent and a viscosity modifier, stirring and aging to obtain the hydrophobic anti-reflection solution. When the surface of the glass is coated with the hydrophobic anti-reflection solution, a dense network nano-protective film is formed on the glass base surface,thereby effectively improving the surface gloss and smoothness of a material; a static contact angle of the glass and water is greater than or equal to 100 degrees, the glass surface reflectivity isreduced by 90% or more, and therefore, the hydrophobic anti-reflection solution not only has the advantages of anti-reflection, easy cleaning, anti-fouling and anti-bacterial effect, but also has relatively high hardness and wear resistance, and can prolong the service life of the glass.

Description

technical field [0001] The invention relates to the technical field of glass product manufacture, in particular to a hydrophobic anti-reflection solution and a hydrophobic anti-reflection glass. Background technique [0002] Glass is a kind of inorganic amorphous material composed of sodium calcium silicate. It is easy to be corroded by air and water vapor, resulting in surface aging, decreased transmittance, and difficult to clean. Glass is also hydrophilic, which will attract and lock a layer of water molecules on the surface, and adhere to dust; in addition, glass is not conductive, and the static electricity generated by friction is not easy to dissipate, and it is easy to absorb sand and dust. Many substances, such as lime deposits, plaster, mortar, sealants, metal oxides, and carbonized food deposits, etc., are firmly attached to the glass surface by chemical means, and it is difficult to remove them with general cleaning methods. A large number of bacteria will adhere...
