Embodiment 1

[0012] Mix tetraethyl orthosilicate, ethanol, water, nitric acid, and ammonia water at a molar ratio of 1:10:8:0.05:0.1, stir for 24 hours, add 12 grams of P123, 8 grams of Tritonx-100 and 6 grams of hexamethylene base imine, stirred for 24 hours, refluxed for 5 hours and left to stand for 72 hours to make a coating material.

[0013] The above materials are uniformly coated on the glass surface, dried in an oven at 100°C for 4 hours, and then heated to 400°C for 2 hours. The anti-reflection rate of the obtained film is 2.2%, and the strength and aging resistance of the film are good.

Embodiment 2

[0015] Mix tetraethyl orthosilicate, ethanol, water, nitric acid, and ammonia in a molar ratio of 1:40:8:0.05:0.1, stir for 24 hours, add 15 grams of P123, 18 grams of Tritonx-100 and 10 grams of hexamethylene base imine, stirred for 24 hours, refluxed for 5 hours and left to stand for 72 hours to prepare a coating solution.

[0016] The above materials are uniformly coated on the glass surface, dried in an oven at 100°C for 4 hours, and then heated to 400°C for 2 hours. The antireflection rate of the obtained film is 2.4%, and the strength and aging resistance of the film are good.

Embodiment 3

[0018] Mix tetraethyl orthosilicate, ethanol, water, nitric acid, and ammonia in a molar ratio of 1:32:8:0.05:0.1, stir for 24 hours, add 18 grams of P123, 10 grams of Tritonx-100 and 15 grams of hexamethylene base imine, stirred for 24 hours, refluxed for 5 hours and left to stand for 72 hours to prepare a coating solution.

[0019] The above materials are evenly coated on the glass surface, dried in an oven at 100°C for 4 hours, and then heated to 400°C for 2 hours. The anti-reflection rate of the obtained film is 2.8%, and the strength and anti-aging performance of the film are good.

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...
