Embodiment 1

[0062] The glass glaze of this embodiment is made of basic glaze and coloring agent, and each component of basic glaze is calculated as follows by weight percentage: 45%SiO 2 ;25%ZnO;3%CaO+MgO;2%BaO;1%SrO;6%B 2 o 3 ;0.5%Al 2 o 3 ;2%TiO 2 ;4%ZrO 2 ;6%K 2 O+Na2 O; 3%Li 2 O; 2.5%CuO; The manufacturing process of glass colored glaze is as follows:

[0063] Put all the raw materials weighed into a ball mill and ball mill for 15 minutes at a speed of 80 rpm, and mix well;

[0064] Melt the obtained mixture at 1250°C to completely melt the mixture to obtain molten glass;

[0065] The molten glass liquid is water-quenched, and the glass frit after water-quenching is put into a ball mill for ball milling for 3 hours at a speed of 100 rpm to obtain glass powder;

[0066] The ball-milled glass powder is dried in a drying oven at 120°C, and the obtained powder is copper red glass glaze.

[0067] The prepared copper-red glass glaze is prepared into a glaze slurry with the blendin...

Embodiment 2

[0072] A glass colored glaze is mainly composed of a base glaze and a colorant, and the components of the base glaze are calculated by weight percentage as follows: 50% SiO 2 ;15%ZnO;5%CaO+MgO;2%BaO;1%SrO;10%B 2 o 3 ;1%Al 2 o 3 ;2%TiO 2 ;2%ZrO 2 ;8%K 2 O+Na 2 O; 3%Li 2 O; 1%CuCO 3 ; The manufacturing process of glass colored glaze is as follows:

[0073] Put all the raw materials weighed into a ball mill and ball mill for 15 minutes at a speed of 80 rpm, and mix well;

[0074] Melt the obtained mixture at 1300°C to completely melt the mixture to obtain molten glass;

[0075] The molten glass liquid is water-quenched, and the glass frit after water-quenching is put into a ball mill for ball milling for 3 hours at a speed of 100 rpm to obtain glass powder;

[0076] The ball-milled glass powder is dried in a drying oven at 120°C, and the obtained powder is copper red glass glaze.

[0077] The prepared copper-red glass glaze and the blending agent are prepared into gla...

Embodiment 3

[0082] A glass colored glaze is mainly composed of a base glaze and a colorant, and the components of the base glaze are calculated by weight percentage as follows: 55%SiO 2 ;15%ZnO;5%CaO+MgO;1%BaO;1%SrO;8%B 2 o 3 ;1%Al 2 o 3 ;0.5%TiO 2 ;11%K 2 O+Na 2 O; 1%Li 2 O; 1.5%CuO; The manufacturing process of glass colored glaze is as follows:

[0083] Put all the raw materials weighed into a ball mill and ball mill for 20 minutes at a speed of 80 rpm, and mix well;

[0084] Melt the obtained mixture at 1300°C to completely melt the mixture to obtain molten glass;

[0085] The molten glass liquid is water-quenched, and the glass frit after water-quenching is put into a ball mill for ball milling for 4 hours, and its rotating speed is 100 rpm to obtain glass powder;

[0086] The ball-milled glass powder is dried in a drying oven at 120°C, and the obtained powder is copper red glass glaze.

[0087] The prepared copper-red glass glaze and the blending agent are prepared into gl...

Abstract

The invention discloses environment-friendly copper ruby glass glaze for float-process flat glass surface decoration, a production method of the environment-friendly copper ruby glass glaze and a method for preparing a copper ruby glass glaze surface from the environment-friendly copper ruby glass glaze. The glass glaze disclosed by the invention is prepared from parent glaze and a colorant, wherein the parent glaze is prepared from the following components: 30-75% of SiO2, 5-20% of B2O3, 5-19% of ZnO, 1-15% of Al2O3, 3-5% of Bi2O3 and 4-25% of R2O (R comprises Li, Na or K) or 3-30% of RO (R comprises Mg, Ca, Ba or Sr). The colorant is one or a mixture of copper oxide, cuprous oxide and copper carbonate. The copper ruby glass glaze disclosed by the invention is free of lead and cadmium, is capable of avoiding injuring a human body or damaging the environment and is specially used for manufacturing a float-process flat glass surface. The copper ruby glass glaze can be regulated to different red colors as required, is suitable for common float-process flat glass and can be tempered and sintered.

Description

technical field [0001] The present invention relates to a lead-free, cadmium-free, environmentally friendly copper-red glass glaze and a preparation method thereof, and in particular to a copper-red glaze, which is specially used for ordinary float flat glass, which can be toughened or sintered, and an environmentally-friendly glass, and a preparation method thereof, as well as a preparation method thereof Glazed method. Background technique [0002] Enamel glass is wear-resistant, acid and alkali resistant, and is widely used in architectural decoration industry, furniture glass, electronic glass, etc. The glazed glass prepared with copper as a colorant has low cost and bright colors, and can be made into orange, red, deep red, dark red and other colors according to the requirements. Traditional glass glazes often use one or more of iron, lead, chromium-containing oxides or cadmium-containing sulfides to introduce red to the glass glaze. However, lead, cadmium, and chromi...
