Embodiment example 1

[0046]The preparation method of the hydrophilic dry-mix colorant applied to the large-scale ceramic plate of the whole body includes:

[0047] This method is based on the preparation process of conventional body color products, by controlling the water content and grinding the powder to a qualified fineness, adding 1-3% selected dispersant, and then using jet mill, ball mill or three-dimensional mixing mixer to stir can be obtained evenly.

[0048] The dispersant is selected from one or more mixtures of microcrystalline cellulose, sodium aluminosilicate, water-soluble anti-caking agent, micropowder silica gel, and its formula is:

[0049] Water-soluble anti-caking agent A 40% Water-soluble anti-caking agent B 40% Water-soluble anti-caking agent C 10%

[0050] Microcrystalline Cellulose 5%. Sodium aluminosilicate 2.5% Micropowder silica gel 2.5%

[0051] The main component of the microcrystalline cellulose is linear polysaccharides bound by β-1,4-glucosidic bonds, and the de...

[0055] The preparation method of the hydrophilic dry-mix colorant applied to the large-scale ceramic plate of the whole body: on the basis of the preparation process of the conventional green body colorant product, after controlling the water content and grinding the powder to a qualified fineness, add 1-3 % selected dispersant, and then use jet mill, ball mill or three-dimensional mixing mixer to stir evenly to get it.

[0056] The dispersant is selected from one or more mixtures of microcrystalline cellulose, sodium aluminosilicate, water-soluble anti-caking agent, micropowder silica gel, and its formula is:

[0057] Water-soluble anti-caking agent A 40% Water-soluble anti-caking agent B 20% Water-soluble anti-caking agent C 20%

[0058] Microcrystalline Cellulose 10% Sodium Aluminosilicate 5% Micronized Silica Gel 5%

[0059] The main component of the microcrystalline cellulose is linear polysaccharides bound by β-1,4-glucosidic bonds, and the degree of polymerization is a...

Abstract

The invention relates to a method for preparing a hydrophilic dry-mixed colorant applied to an entire-body large-size ceramic sheet material. The method comprises the steps: (1) treating raw materials, wherein the raw materials comprise colorants, a color supporting matrix and a mineralizer with the particle size of 200 to 400 meshes, and a dispersant is premixed according to a formula for later use; (2) proportioning and mixing the raw materials: subjecting various ceramic colorants to weighing and matching, then, loading the mixture to a mill for crushing, and carrying out mixing, drying andscreening; (3) carrying out saggar loading and firing: loading the uniform-mixed and dried green stock to a refractory saggar for calcining according to colorant requirements; (4) carrying out saggardischarging, coarse breaking and fine crushing: carrying out coarse breaking and fine crushing according to set fineness after a calcined matrix colorant is discharged from the saggar, and carrying out fine milling or stirring milling with a ball mill until the fineness is 325 meshes; (5) carrying out repeated washing with hot and cold water or diluted hydrochloric acid until a required pH valueis achieved, carrying out separating, and then, carrying out drying, powdering and screening until the fineness is 325 meshes, wherein the moisture content after drying is lower than 0.5%; and (6) adding 1% to 3% of dispersant, carrying out mixing modification with a three-dimensional mixer or airflow mill, and carrying out packaging and warehousing.

Description

technical field [0001] The invention relates to the technical field of ceramic tile manufacture, in particular to a method for preparing a hydrophilic dry-mix colorant applied to whole-body large-size ceramic plates. Background technique [0002] At present, the known production technology of ceramic tiles is wet mixing or the combination of wet and dry color mixing. In contrast, the wet process is a complete system, including ball mills, spray towers, underground slurry tanks, etc., adding color materials After that, all the equipment will be polluted. If it is necessary to make other powders of different colors, it must be cleaned. The labor intensity is high, the production cost is high, and the pollution is also very large. The amount of one-time preparation is too large. If the production output is not accurate, prepare more The colored powder produced needs to be poured out or pressed into the warehouse, resulting in waste. The advantages of the dry process are relati...
