Problems solved by technology

There are also some colored glasses obtained by coating or spraying a layer of varnish or raw lacquer with organic pigments on the surface of ordinary plain white or ultra-white glass, but this method has defects because the quality and durability of the coating will deteriorate over time. Aging, and thermal shock will also cause the coating to peel off, and the color will naturally lighten accordingly
In addition, the traditional amber glass is based on the soda-lime-silica glass system, the strength and impact resistance of the glass are poor, and it is brittle when subjected to external force, while the amber colored glass based on high-strength and high-hardness aluminosilicate glass is There are no reports and related products

Embodiment Construction

[0019] The present invention is described below in conjunction with embodiment.

[0020] According to the mass percentage of the following oxides in amber aluminosilicate glass: SiO 2 65%;Al 2 o 3 13.5%; Na 2 O 13.5%; K 2 O 1.5%; MgO 3.5%; CaO 2.5%; WO 3 0.08%; SO 3 0.3%.

[0021] The following raw materials were weighed, prepared and mixed uniformly to form an amber aluminosilicate glass batch:

[0022] Feldspar 312g, silica sand 52g, dolomite 36.8g, limestone 1.9g, soda ash 90.8g, iron oxide 0.16g, tungsten disulfide 0.05g, calcium sulfide 2g, carbon powder 0.4g, mix well and put into corundum crucible for melting system, the melting temperature is 1660°C, and the melting atmosphere is controlled to be reducing, according to the Fe content in the molten glass 2+ / Fe 3+ Ratio to control the amount of carbon added, when Fe 2+ / Fe 3+ When ￡0.6, increase the amount of carbon powder, when Fe 2+ / Fe 3+ When 30.6, stop increasing the content of carbon powder; and t...

Abstract

The invention discloses a piece of amber alumina silicate glass. The amber alumina silicate glass is characterized by also comprising the following components: 0.06%-0.3wt.% of WO3, and 0.2%-0.5wt.% of SO3. The invention also provides a preparation method for the amber alumina silicate glass. The preparation method comprises the following steps of adding 0.001wt.%-0.05wt.% of tungsten disulfide and 0.1wt.%-5wt.% calcium sulphide, relative to the total amount of batch, into the batch of normal alumina silicate glass so as to form the batch of the amber alumina silicate glass, and preparing the amber alumina silicate glass according to a known technology, wherein the melting temperature is 1630-1680 DEG C, the glass mold temperature is 1580-1620 DEG C, and the annealing temperature is 660-680 DEG C. The prepared amber alumina silicate glass comprises no harmful components, and has less environment pollution.

Description

technical field [0001] The invention relates to a batch material for preparing amber aluminosilicate glass and a preparation method thereof, belonging to the field of colored glass preparation, in particular to a batch material obtained by adding tungsten disulfide and calcium sulfide, which is used to obtain aluminosilicate glass Amber glass tinted in a salt glass body. [0002] Background technique [0003] Traditional amber glass is obtained by adding cadmium and selenium to the glass body, but cadmium and selenium are harmful to the environment and even banned by legislation in some countries. There are also some colored glasses obtained by coating or spraying a layer of varnish or raw lacquer with organic pigments on the surface of ordinary plain white or ultra-white glass, but this method has defects because the quality and durability of the coating will deteriorate over time. Aging and thermal shock will also cause the coating to peel off, and the color will natural...
