Embodiment 1

[0113] This embodiment discloses a kind of preparation method of red glaze, comprises the following steps:

[0114] (1) Prepare the following raw materials in parts by mass: 31 parts of potassium feldspar, 6 parts of albite, 6 parts of ball clay, 19 parts of hard kaolin, 12 parts of calcined talc, 7 parts of limestone, 22 parts of quartz powder, barium carbonate 2 parts, 8 parts of red color base.

[0115] (2) Ball milling: use a ball mill to mill the raw materials; the mass ratio of raw materials: ball material: water in the ball mill is 1:2.5:0.8. The pellets include 30% pellets with a specification of 20-35mm, 50% pellets with a specification of 45-65mm, and 20% pellets with a specification of 65-80mm. During the ball milling process, 0.3% sodium carboxymethyl cellulose based on the weight of the raw materials was added. The fineness of the raw material after ball milling is controlled to 0.06-0.3% of the 360-mesh sieve.

Embodiment 2

[0133] In the present embodiment, a kind of preparation method of red glaze comprises the following steps:

[0134] (1) Prepare the following raw materials in parts by mass: 28 parts of potassium feldspar, 5 parts of albite, 5 parts of ball clay, 19 parts of hard kaolin, 10 parts of calcined talc, 6 parts of limestone, 22 parts of quartz powder, barium carbonate 1.2 parts, 7 parts of red color base.

[0135] (2) Ball milling: use a ball mill to mill the raw materials; the mass ratio of raw materials: ball material: water in the ball mill is 1: 2.4-2.6: 0.7-0.9. The pellets include 25% pellets with a specification of 20-35mm, 52% pellets with a specification of 45-65mm, and 23% pellets with a specification of 65-80mm. During the ball milling process, 0.3% sodium carboxymethyl cellulose based on the weight of the raw materials was added. The fineness of the raw material after ball milling is controlled to be 0.06-0.3% on a 360-mesh sieve.

Embodiment 3

[0142] A kind of preparation method of present embodiment red glaze comprises the following steps:

[0143] (1) Prepare the following raw materials in parts by mass: 28 parts of potassium feldspar, 5 parts of albite, 5 parts of ball clay, 19 parts of hard kaolin, 10 parts of calcined talc, 6 parts of limestone, 22 parts of quartz powder, barium carbonate 1.2 parts, 7 parts of red color base.

[0144] (2) Ball milling: use a ball mill to mill the raw materials; the mass ratio of raw materials: ball material: water in the ball mill is 1: 2.4-2.6: 0.7-0.9. The pellets include 32% pellets with a specification of 20-35mm, 46% pellets with a specification of 45-65mm, and 22% pellets with a specification of 65-80mm. Add 0.32% sodium carboxymethyl cellulose in the ball milling process based on the weight of the raw material. The fineness of the raw material after ball milling is controlled to be 0.06-0.3% on a 360-mesh sieve.

Abstract

The invention belongs to the technical field of electric porcelain glazes, and particularly relates to a red glaze and a preparation method thereof, and the preparation method of the red glaze comprises the following steps: (1) preparing the following raw materials: potassium feldspar, albite, ball clay, hard kaolin, calcined talc, limestone, quartz powder, barium carbonate and a red color base; (2) performing ball milling: carrying out ball milling on the raw materials by using a ball mill; wherein the mass ratio of the raw materials to the ball materials to the water in the ball mill is 1: (2.4-2.6): (0.7-0.9); (3) performing iron removal treatment; and (4) aging. After the prepared red glaze and a green body form porcelain, the surface of the porcelain body is bright red, smooth, bright, fine, mild and moist, and the requirements of customers on red electric porcelain can be well met. Moreover, the red glaze in the scheme can be well combined with a green body, an excellent middle layer can be generated between the glaze and the green body after the red glaze is formed into the porcelain, the performance of the porcelain can be greatly improved (the strength of the porcelain isimproved by 22% or above), and the development of the red glaze achieves the design purpose and meets the process and industry standards of companies.

Description

technical field [0001] The invention belongs to the technical field of electric porcelain glazes, and in particular relates to a red glaze and a preparation method thereof. Background technique [0002] The surface of electric porcelain is usually coated with electric enamel. Electric enamel refers to the glaze applied on the surface of electric porcelain products. Coating glaze can improve the electrical performance, mechanical strength and chemical stability of electric porcelain, and make the surface of porcelain body smooth and beautiful. Easy to clean. With the rapid development of the electric power industry, the voltage level continues to increase. The voltage level is widely distributed between 110KV-1000KV, and the types of high-voltage and ultra-high-voltage insulators used are also various. The green body is made (high-grade green body, low-grade green body), and the structure and composition of different electric porcelain products are not the same, especially t...
