Abstract

The invention discloses a preparation method of high temperature resistant yellow glass. The preparation method comprises the following steps: uniformly mixing 90-110 parts of silicon dioxide, 3-7 parts of zirconium dioxide, 2-10 parts of phosphorus pentoxide, 4-12 parts of aluminium oxide, 1.5-5 parts of limestone, 0.5-1.2 parts of nickel oxide, 0.02-0.08 part of ferric oxide and 0.01-0.05 part of cadmium sulfide, melting the mixture to obtain molten glass, quenching the molten glass in room-temperature water, taking out the molten glass, drying and ball-milling the molten glass to obtain colorant glass, then uniformly mixing 90-110 parts of silicon dioxide, 3-7 parts of zirconium dioxide, 2-10 parts of phosphorus pentoxide, 4-12 parts of aluminium oxide, 1.5-5 parts of limestone and 0.5-1.2 parts of nickel oxide with the colorant glass, melting the mixture and forming, insulating and cooling the product to room temperature, thus obtaining the high temperature resistant yellow glass. The high temperature resistant yellow glass has excellent high temperature resistance, is not liable to undergo expansion cracking continuously under the blazing sun, is uniform in coloring and has good transmission of light.

Description

technical field [0001] The invention belongs to the field of preparation methods of colored glass, in particular to a preparation method of high-temperature-resistant yellow glass. Background technique [0002] With the improvement of people's living standards, colored glass has attracted more and more attention. At present, there are two production methods of colored glass: one is bulk colored glass formed by high-temperature melting; the other is colored glass formed by ion diffusion on the glass surface. The colored glass prepared by the melting method not only uses a large amount of colorant, but also needs to be melted at a higher temperature. At the same time, this method usually requires secondary color development of the product at a certain temperature to achieve the color The purpose of bright colored glass, so its preparation process is more complicated. Surface ion diffusion tinted glass was successfully developed by Bohemians in 1932. The preparation process ...
