Problems solved by technology

But, according to this ceramic color glaze production process method, there are many weak points in the product produced: the brilliance degree of the color rendering of color is more dependent on the basic glaze, and the chemical composition of the basic glaze has a great influence on the color development of the pigment. Considerable influence, so different coloring pigments are required to have different basic glazes to match them, so as to achieve the best color development effect, so it is more technically difficult to ensure that each color achieves the best color development effect Large, and the process is more complicated; the color difference is easy to occur at the corners of ceramic products, especially the color difference of special-shaped and large-scale products is particularly obvious, because the ceramic glaze is in a glass rheological state at high temperature, and under the action o

Embodiment 1

[0034] Embodiment 1: Take the ceramic wrapped scarlet pigment and water to prepare according to the weight ratio of 10:7, and add the colorant suspending agent (ammonium chloride) with a weight percentage of 1.2% to mix and stir evenly, and then take the method of dipping or spraying Fix the prepared wrapped bright red pigment on the ceramic body, and a pigment layer with a thickness of 0.02-0.15mm will be formed on the ceramic body, and then fired at a temperature of 1250°C with an oxidizing flame at a high temperature. The constant temperature time is 80 minutes, and the firing cycle is 10 hours. After high-temperature firing, the bright red pigment will be firmly sintered on the surface of the ceramic body, and then the basic glaze will be fixed on the porcelain surface by dipping or spraying. 1100℃ glaze firing temperature oxidizing flame firing, high temperature constant temperature time is 60 minutes, firing cycle is 6 hours, so that it can be fired into a kind of uniform...

Embodiment 2

[0035] Embodiment 2: Get ceramics to wrap golden yellow pigment and water according to the weight ratio and prepare as 5: 3, and add the colorant suspending agent (magnesium chloride) weight percentage is 2.5%% and mix and stir evenly, then take the mode of soaking or spraying The prepared wrapped golden yellow pigment is fixed on the ceramic body, and a layer of pigment layer with a thickness of 0.02-0.15mm will be formed on the ceramic body, and then fired at a temperature of 1270°C with an oxidizing flame at high temperature and constant temperature. The time is 80 minutes, and the firing cycle is 10 hours. After high-temperature firing, the golden pigment will be firmly sintered on the surface of the ceramic body, and then the basic glaze will be fixed on the vitrified ceramic surface by dipping or spraying. Finally, at 1130 ℃ glaze firing temperature oxidizing flame firing, high temperature constant temperature time is 60 minutes, firing cycle is 6 hours, so that it can be...

Embodiment 3

[0036] Embodiment 3: Get ceramics to wrap crimson pigment and water according to the weight ratio and prepare as 5: 2, and add the color material suspending agent (ammonium chloride) weight percentage is 0.8% to mix and stir evenly, then take dipping or spraying The method is to fix the prepared wrapped deep red pigment on the ceramic body, and a pigment layer with a thickness of 0.02-0.15mm will be formed on the ceramic body, and then fired at a temperature of 1265°C with an oxidizing flame. The high-temperature constant temperature time is 80 minutes, and the firing cycle is 10 hours. After high-temperature firing, the deep red pigment will be firmly sintered on the surface of the ceramic body, and then the basic glaze will be fixed on the vitrified ceramic surface by dipping or spraying. Finally, it is fired in an oxidizing flame at a glaze firing temperature of 1150°C. The high temperature and constant temperature time is 60 minutes, and the firing cycle is 6 hours. In this...

Abstract

The invention discloses ceramic glaze, belonging to the technical field of ceramic materials and comprising basic glaze and coloring pigments, wherein the basic glaze comprises the following components by weight percent (wt%): 45% to 60% of SiO2, 7% to 12% of Al2O3, 5% to 12% of CaO, 0% to 5% of MgO, 0% to 5% of P2O5, 0.5% to 5% of SrO, 2% to 8% of ZnO, 1% to 7% of K2O, 1% to 5% of Na2O, 0.5% to 5% of Li2O, 1% to 8% of B2O3 and 0% to 4% of ZrO2. By separating the coloring pigments in colored glaze from the basic glaze and baking the coloring pigments at different temperatures for twice, the invention solves the problems that the product of colored ceramic glaze has poor color difference and color development and leads to pollution caused by heavy metals, such as lead, cadmium and the like, and the problem that the colored pigments or metal oxides are dependent on the basic glaze at the same time; and the invention lessens the difficulty in producing the colored ceramic glaze.

Description

technical field [0001] The invention belongs to the technical field of ceramic glazes, in particular to a ceramic color glaze and a process for preparing the color glaze. Background technique [0002] The production process of the traditional ceramic color glaze in the daily-use ceramic industry is: adding ceramic coloring pigments or metal oxides to the base glaze in a certain proportion, and ball milling and mixing together to make a color glaze, and then adopting dipping or spraying glaze. The method is to fix the color glaze on the ceramic body to form a 0.1-0.3mm color glaze layer, and finally fire the product with the color glaze according to the required firing temperature and firing system to obtain a colored glaze. Colorful ceramics. But, according to this ceramic color glaze production process method, there are many weak points in the product produced: the brilliance degree of the color rendering of color is more dependent on the basic glaze, and the chemical comp...
