Embodiment 1

[0021] The preparation method of blue crystal glass plate comprises the following steps:

[0022] (1) Preparation of colorless crystal glass liquid: prepare low-viscosity colorless crystal glass liquid by melting the raw materials at 1500°C according to the following weight percentage formula: SiO 2 : 67-69%, Al 2 o 3 : 1.5-1.8%, K 2 O: 6-7%, Na 2 O: 10.2-10.6%, CaO: 8-9%, BaO: 2-2.5%, B 2 o 3 : 1.4-1.8%, clarifying agent As 2 o 3 : 0.4-0.6%, harmful components control Fe 2 o 3 ≤0.005%;

[0023] (2) Preparation of ultra-concentrated glass coloring powder: add the raw material of sapphire glass coloring powder into an electric heating platinum crucible for melting, then water-quench and granulate, and then grind with a small ball mill to obtain super-concentrated sapphire glass coloring powder; among them, sapphire The raw material weight ratio of glass coloring powder is: SiO 2 : 65.5-66.5%, CoO: 3.5-4.5%, Na 2 O: 12-14%, CaO: 8.5-9.5%, Al 2 o 3 : 2.5-3.5%, B 2 ...

Embodiment 2

[0027] The preparation method of green crystal glass plate comprises the following steps:

[0028] (1), preparation colorless crystal glass liquid step is with embodiment 1;

[0029] (2) Preparation of ultra-concentrated glass coloring powder: add the green crystal glass coloring powder raw material into an electric heating platinum crucible, supplemented with a certain amount of carbon powder, melt it in a reducing atmosphere, and then granulate it with water quenching, and then grind it with a small ball mill to obtain a super concentrated glass coloring powder. Concentrated green crystal glass coloring powder; wherein, the raw material weight ratio of green crystal glass coloring powder is: SiO 2 : 67.5-68.5%, Cr 2 o3 : 4-6%, Na 2 O: 10-11%, CaO: 8-9%, Al 2 o 3 : 4-5%, B 2 o 3 : 4-5%;

[0030] Step (3) is the same as in Example 1, and the green crystal glass plate finished product is obtained.

Embodiment 3

[0032] The preparation method of lake blue crystal glass plate comprises the following steps:

[0033] (1), preparation colorless crystal glass liquid step is with embodiment 1;

[0034] (2) Preparation of ultra-concentrated glass coloring powder: adding the lake blue crystal glass coloring powder raw material into an electric heating platinum crucible for melting, then water quenching and granulation, and then grinding by a small ball mill to obtain super concentrated lake blue crystal glass coloring powder; Wherein, the raw material weight ratio of lake blue crystal glass coloring powder is: SiO 2 : 66-67%, CuO: 8-9%, Na 2 O: 7.5-8.5%, CaO: 9-10%, Al 2 o 3 : 0.8-1.5%, B 2 o 3 : 5-6%;

[0035] Step (3) is the same as in Example 1, and the lake blue crystal glass plate finished product is obtained.

Abstract

The invention discloses a method for preparing a superconcentrate glass pigment and a color crystal glass plate. The glass pigment comprises the following raw materials of SiO2, Na2O, CaO, Al2O3, B2O3 and one of the color mixing raw materials of CoO, Cr2O3, CuO, MnO2, Se, CdS, TiO2 and CeO2 or mixture of two of the color mixing raw materials, wherein the adding proportion of the color mixing raw material accounts for 0.2-10% of the total weight percentage of the pigment raw material, and the adding amount of the color mixing raw material is 5-30 times more than the conventional adding amount. The melting point of the superconcentrate glass pigment is low, the coloring is carried out at moderate temperature, and the coloring process is easy to control and is stable. The invention has the advantages of simple method, convenient operation and convenient coloring, decreases the defective rate of colored product, and reduces the production cost. The prepared color crystal glass sheet has stable color and high transparency.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to a method for preparing super-concentrated glass coloring powder and a colored crystal glass plate. Background technique [0002] The traditional coloring of crystal glass is to add a small amount of glass colorant when melting the glass, and various colored glasses can be made. Addition of copper(II) oxide or chromium(III) oxide produces green; cobalt(II) oxide produces blue; manganese dioxide produces purple; tin dioxide or calcium fluoride produces milky white; uranium compounds produce yellow-green fluorescence; colloidal selenium Red jade color is produced; colloidal gold produces red, reddish purple or blue; cuprous oxide produces red, green or blue; ferrous compounds produce green, and when the amount is large, it becomes black; iron (III) compounds produce yellow. The method of adding coloring agent adopts forehearth to carry out coloring, but the adding amount of coloring...
