Coating material capable of reducing light reflection of glass surface

Abstract

The invention discloses a coating material capable of reducing light reflection of a glass surface. The coating material comprises the components of ethyl orthosilicate, ethanol, water, nitric acid and ammonia water and the auxiliary agents of ethyl orthosilicate, P123, Tritonx-100 and hexamethyleneimine. A film formed after the coating material provided in the invention is coated on a glass surface is composed of cylindrical protrusions which present a certain rule and are vertically arranged, and the top of each of the cylindrical protrusions is semispherical, which enables the refractive index of the glass surface to gradiently vary when only one layer of the film is coated on the glass surface, thereby enabling reflectivity of the glass surface to be reduced.

Description

technical field

[0001] The invention relates to a coating material, in particular to a coating material for reducing light reflection on a glass surface. Background technique

[0002] At present, widely used lamps and lanterns all use glass as the light-transmitting medium. The light transmittance of ordinary glass can only reach 92%, and the low light transmittance seriously affects the light transmission of the lamp.

[0003] The refractive index of glass is about 1.5, reducing the light reflection of glass can improve the light transmittance of glass. When making lampshades in the glass production industry, the content of impurities in the glass is generally reduced as much as possible, especially the iron content in the glass, so as to reduce the absorption of light by the glass body, and reducing the impurities of the glass body will greatly increase the production cost and cost of the glass. manufacturing difficulty.

[0004] The researchers found that the porous spo...
