Problems solved by technology

This kind of glass has poor heat absorption performance
[0004] The glass composition (200680011222.7) applied by Saint-Gobain Glass Company for the manufacture of glass windows that absorb ultraviolet rays and infrared rays: 65-80wt% SiO 2 , 0-5wt% Al 2 o 3 , 0-5wt% B 2 o 3 , 5-15wt% CaO, 0-2wt% MgO, 9-18wt% Na 2 O, 0-10wt% K 2 O, 0-5wt% BaO, 0.7-1.6wt% Fe 2 o 3 , 0.1-1.2wt% CeO 2 , 0-1.5wt% TiO 2 The redox ratio is less than 0.23; the visible light transmittance LTA≥70%, the infrared transmittance 28%, the ultraviolet transmittance 18%, and the total solar energy transmittance TSET≥48% of the glass 4mm thick. The amount of iron is too high, the temperature difference between the upper and lower sides of the glass liquid is nearly 300 degrees, the molding process is difficult, and mass production cannot be implemented
[0005] In addition, at present, most of the anti-reflection and anti-glare glass of chemical erosion is frosting process and the introduction of Danish SUNARC technology. The visible light transmittance of general frosting process glass will drop by 2 to 3 percentage points on the original basis; the glass prepared by Danish SUNARC technology It can reduce anti-reflection and anti-reflection, but SUNARC technology uses fluorine-containing mixed acid etching, which has adverse effects on the environment, and the production and environmental protection costs are high

Embodiment Construction

[0022] In order to better understand the present invention, the present invention will be described in more detail through the following examples, but the present invention is not limited to the following examples; the ingredients of the examples are formulated according to Table 1.

[0023] Table 1 comparative sample and embodiment composition content and material recipe table

[0024]

[0025] According to the high-temperature melting scheme 1 in the above table, introduce the above basic components through ultra-white silica sand, dolomite, limestone, soda ash, alumina, Glauber's salt, etc., of which Glauber's salt is used as a melting clarifier with a purity of more than 99.5%. Mix well, put it into a quartz crucible, place it in a high-temperature furnace and heat it to 1500°C, and keep it warm for 2 hours. Cast the molten glass onto a preheated graphite plate and place it in a holding furnace at 600°C for annealing. After rough grinding and polishing, a sample with a...

Abstract

The invention belongs to the application fields of glass materials and surface modification technology, and relates to a preparation method of glass with functions of absorbing ultraviolet and infrared rays and preventing glaring. For a glass main body, a glass substrate with the function of absorbing ultraviolet and infrared rays is prepared at the melting temperature of 1500 DEG C; for the surface modification part, water, a complexing agent, polyalcohol and alkali are mixed according to a certain molar proportion to prepare a chemical etching complex liquid; and the glass substrate needingto be treated is cleaned and then put into the chemical etching complex liquid to perform chemical reaction. The glass disclosed by the invention has a visible light transmittance of 70% at the thickness of 4mm, which is lower than the ultraviolet ray transmittance of 20%, and lower than the infrared ray transmittance of 40%, and meanwhile, the glassiness is 85Gu, a certain anti-glaring function is achieved, and the production cost is low. The glass disclosed by the invention can be widely applied to the fields of protective fields of building glass, automobiles windshield glass, spectacle glass, experimental apparatus and the like, and has a certain energy-saving effect and safety.

Description

technical field [0001] The invention belongs to the application field of glass technology, and in particular relates to a preparation method of glass with the function of absorbing ultraviolet and infrared rays and preventing glare. Background technique [0002] In recent years, due to the destruction of the ozone layer by human activities, ultraviolet rays can penetrate the atmosphere and reach the surface of the earth, causing a series of changes in human body functions, especially causing adverse effects on human skin, eyes and immune system; The penetration of thermal radiation to the skin exceeds that of ultraviolet rays. Excessive infrared rays will cause red papules on the skin, and even cause the temperature of the skin to rise and telangiectasia and congestion through the thermal radiation effect. Thermal radiation causes the surface temperature to be higher, which greatly increases The air conditioning load consumes a lot of energy; the light pollution reflected by...
