Problems solved by technology

Glass color glaze is an important raw material for the preparation of colored glaze glass, but the color glaze traditionally used contains toxic heavy metals such as lead, has poor chemical stability, and is easily corroded by sulfides in the atmosphere and turns black. In addition, lead-containing glass is easy to precipitate lead during contact with acid, which is harmful to human health
Traditional colored glazes are often difficult to meet the requirements of modern environmental protection. Therefore, there is an urgent need for new lead-free environmentally friendly colored glazes suitable for the preparation of colored glazes
[0003] There are bismuth glaze, molybdenum glaze, and zinc glaze that can replace lead glaze. Although bismuth glaze and molybdenum glaze have excellent performance, it is difficult to reduce the cost of glass colored glaze, which affects the popularization and application of this system glaze

Embodiment 1

[0058] A glass 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: 25% SiO 2 , 30%ZnO, 2.5%CaO+MgO, 10%BaO, 5.0%B 2 o 3 , 6.0%Al 2 o 3 , 10%TiO 2 , 2.0%ZrO 2 , 6.5%K 2 O+Na 2 O, 3.0% Li 2 O; The manufacturing process of glass colored glaze is as follows:

[0059] Weigh the above-mentioned formula raw materials according to weight percentage and put them in a mixer for stirring or ball milling in a ball mill for 10 minutes at a speed of 100 rpm, and mix well;

[0060] Place the mixed batch in the furnace and melt the batch at 1000°C;

[0061] Quenching the molten batch with water to obtain the basic glaze;

[0062]Grind the basic glaze into powder, put it in a ball mill with 15% blue pigment and mill it for 1 hour at a speed of 100 rpm, and mix thoroughly to form a glaze.

[0063] When in use, the ratio of glass color glaze to blending agent is 65:35. It can be used directly aft...

Embodiment 2

[0065] A glass color glaze is mainly composed of a base glaze and a colorant, and the components of the base glaze are calculated as follows in weight percentage: 31%SiO 2 , 5%ZnO, 3.0%CaO+MgO, 10%SrO, 19%B 2 o 3 , 11%Al 2 o 3 , 5%TiO 2 , 6.0%K 2 O+Na 2 O, 10% Li 2 O; The manufacturing process of glass colored glaze is as follows:

[0066] The raw materials of the above formula are weighed according to the weight percentage and placed in a mixer or ball mill for 15 minutes at a speed of 80 rpm, fully mixed evenly;

[0067] Place the mixed batch material in the furnace and melt the batch material at 1150°C;

[0068] Quenching the molten batch with water to obtain the basic glaze;

[0069] Grind the basic glaze into powder, and place it with 19% red pigment in a ball mill for 5 hours at a speed of 70 rpm, and mix thoroughly to form a glaze.

[0070] When in use, the ratio of glass color glaze to blending agent is 75:25. It can be used directly after grinding and mixing...

Embodiment 3

[0072] Glass color glaze of the present invention is mainly made of basic glaze and coloring agent, and each component of basic glaze is calculated as follows by weight percentage: 42%SiO 2 , 30%ZnO, 2.0%CaO+MgO, 3%BaO, 1.0%SrO, 5%B 2 o 3 , 0.5%Al 2 o 3 , 2.5%TiO 2 , 10%ZrO 2 , 1%K 2 O+Na 2 O, 3.0% Li 2 O; The manufacturing process of glass colored glaze is as follows:

[0073] The above-mentioned formula raw materials are weighed by weight percentage and placed in the ball mill for 18 minutes in the agitator ball mill at a speed of 73 revolutions per minute, fully mixed evenly;

[0074] Place the mixed batch in the furnace and melt the batch at 1200°C;

[0075] Quenching the molten batch with water to obtain the basic glaze;

[0076] Grind the basic glaze into powder, and put it in a ball mill with 8% white pigment for 4 hours, and the speed is 85 rpm, and mix well to form a glaze.

[0077] When in use, the ratio of glass color glaze to blending agent is 70:30. It ...

Abstract

The invention relates to a leadless environmentally-friendly glass glaze. The leadless environmentally-friendly glass glaze comprises base glaze, and the base glaze comprises 25-60wt% of SiO2, 5-30wt% of ZnO, 1-8wt% of CaO + MgO, 0-10wt% of BaO, 0-10wt% of SrO, 5-33wt% of B2O3, 0.5-11wt% of Al2O3, 0.5-10wt% of TiO2, 0-10wt% of ZrO2, 1-22wt% of K2O +Na2O and 1-10wt% of Li2O. The environmentally-friendly glass glaze contains no lead, can avoid damages to human bodies and the environment, can substitute traditional lead-containing glazes, has a lower price than leadless bismuth-containing glazes, is suitable for common flat glass, and can be toughened or sintered.

Description

technical field [0001] The invention relates to a glass colored glaze and a preparation method thereof, in particular to a temperable or sinterable lead-free environmentally friendly glass colored glaze suitable for ordinary flat glass, a preparation method thereof and a method for preparing a glazed surface thereof. Background technique [0002] Enamel glass is wear-resistant, has a certain acid and alkali resistance, and is also functional and decorative.
