Abstract

The invention relates to a preparation method of leopard dot pattern glaze. The method is to prepare the main base glaze and auxiliary glaze separately, and then mix them and apply them on the green body. The main base glaze components are potassium feldspar, frit, calcite, quartz, Guizhou soil, zinc oxide, manganese carbonate, and calcined iron. red. The secondary glaze components are frit, feldspar, calcite, zinc oxide, Guizhou soil and quartz. The frit components are borax, quartz, potassium feldspar, crushed glass powder and potassium carbonate. The frit is dry ground and fired for preparation; the main base glaze is ground by dry method, and the auxiliary glaze is ball milled by wet method. The main and auxiliary glazes are adjusted to the same Baume degree, and the ratio of main and auxiliary glazes is 1:1. The ratio of ~1.8 is prepared, and the body is glazed by spraying glaze. The thickness of the glaze is 1.2mm. Since the two glaze components contain zinc, iron, manganese, and other supersaturated crystalline raw materials, through the double-layer glaze color reaction, the rapid Fired in a tunnel kiln; the resulting glaze is bright and has the color of leopard fur, which is excellent for decorating daily-use porcelain.

Description

A kind of preparation method of leopard pattern glaze

technical field

The invention relates to a preparation method of leopard dot pattern glaze.

Background technique

At present, in the porcelain industry, the shape of the body is very important, and the deployment of glaze can better show the beauty of the product. The body of the same shape often has different effects on the vision of consumers due to different glazes. In porcelain The color and pattern of the surface directly affect the beauty of the product and the user's liking. The same shape of the body has different visual effects for consumers due to different glaze colors. Making glazes with patterns, such as animal fur spots and colors, requires hand-painted glazes, which is time-consuming and laborious, and the efficiency is not high.

Contents of the invention

The purpose of the present invention is to prepare a leopard-spot pattern glaze which has the same glaze color effect as leopard fur, can be fired in a fast tunnel kiln at 1180°C to 1196°C, and can achieve the same color as leopard fur.

In the present invention, the main base glaze, auxiliary glaze and frit are prepared separately, and then mixed and applied to the green body, and the ingredients are prepared according to a given formula. Since the two glaze components contain zinc, iron, manganese, and other supersaturated crystallization raw materials, through the double layer Glaze color reaction, put it into a fast tunnel kiln and fire it in an oxidizing atmosphere at 1180 ℃ ~ 1196 ℃ to get a bright glazed surface with the color of leopard fur.

The technical solution of the present invention: a method for making leopard-spot pattern glaze, which includes formula ingredients—making frit—ball milling and sieving—modulation, which is characterized in that:

(1) Prepare materials according to the following weight ratio formula—

A. The main base glaze is prepared according to the following weight ratio formula—

Potassium feldspar 26-36%, frit 18-28%, calcite 5-13%, quartz 9-15%,

Guizhou soil 1-5%, zinc oxide 2-6%, manganese carbonate 4-8%, calcined iron red 8-16%; the sum of the percentages of each component is 100%; calcined iron red is iron powder after Iron red raw material obtained after calcining at 1250°C;

B. Preparation of the following weight ratio formulas for auxiliary glazes—

Frit 26-34%, potassium feldspar 15-25%, calcite 12-18%, zinc oxide 7-13%,

Guizhou soil 3-7%, quartz 15-25%, appropriate amount of pigment;

The sum of the percentages of each component is 100%; the color material is red or yellow color material, and the amount of color material added is based on the depth of the required color;

C, described frit is prepared according to the following weight ratio formula—

Borax 26-34%, Quartz 15-25%, Potassium feldspar 15-25%,

Glass 15-25%, potassium carbonate 1-3%; the sum of the percentages of each component is 100%;

(2) Making frits: dry-grind the above frit ingredients, and then burn them at 1300°C to make frits for later use;

(3) Ball milling and sieving: the main base glaze is ground by dry method, passed through a 250-mesh sieve, and the sieve residue is less than 0.3;

The auxiliary glaze is ball milled by wet method, selected material: ball: water = 1:2:0.5, when ball milling, add 5% clay to 100% auxiliary glaze, pass through a 250-mesh sieve, and the sieve residue is less than 0.3;

(4) Preparation: first adjust the main base glaze and auxiliary glaze to the same concentration according to the Baume degree, that is, adjust the glaze slurry with a concentration between 40 and 50 Baume degrees; then adjust the main and auxiliary glazes to 1 : 1～1.8 proportioning modulation, carry out wet method ball mill again and pass through 325 mesh sieves, sieve residue is less than 0.5, Baume degree is between 40～50;

The glaze is sprayed on the body by spraying glaze, the glaze thickness is 1.2mm, and it is put into a fast tunnel kiln and fired in an oxidizing atmosphere at 1180°C to 1196°C. The resulting glaze is bright and has a flower like leopard fur. Surface, decorative daily porcelain effect is excellent.

In the present invention, the main base glaze, auxiliary glaze and frit are prepared separately, and then mixed and applied to the green body, and the ingredients are prepared according to a given formula. Since the two glaze components contain zinc, iron, manganese, and other supersaturated crystallization raw materials, through the double layer Glaze color reaction, firing in a fast tunnel kiln, the resulting glaze is bright and has the color of leopard fur, so it is named leopard spot pattern glaze, which is very effective in decorating daily-use porcelain.
