METHOD FOR PRODUCING TEXTURED GLASS SUBSTRATE WITH APPLIED ANTI-REFLECTING COATING OF SOL-GEL TYPE Russian patent published in 2022 - IPC C03C17/25 

FIELD: building materials.

SUBSTANCE: invention relates to a method for producing material containing textured glass substrate covered on at least one of its textured surfaces with anti-reflecting coating of sol-gel type based on porous silica. The method contains following stages: a stage of application to the mentioned at least one textured surface of the mentioned substrate of a solution containing at least one silica precursor compound and at least one pore agent, and a stage of heat processing at a temperature of 400°C and more, intended for strengthening the mentioned anti-reflecting coating. Before the mentioned application stage, glass substrate is heated so that the mentioned textured surface intended for the application of anti-reflecting coating to it has a temperature in the range of 30-100°C, in particular 50-80°C right before the application stage. Material can be used in greenhouse structure.

EFFECT: creation of coating, homogenous by thickness, providing an increase in light transmittance coefficient.
