Embodiment

[0039] A method for preparing lead-free easy-to-clean industrial porcelain, comprising the steps of:

[0040] 1) Preparation of blank;

[0041] 30 parts of coal gangue, 15 parts of feldspar, 10 parts of calcined high-alumina bauxite, 6 parts of jiexiu soil, 5 parts of Zimujie soil, 1 part of Suzhou soil, 5 parts of Fangzi soil, and 1 part of cooked talc.

[0042] 2) Preparation of the glaze: prepare the glaze according to the prior art, wherein the average fineness of the glaze is 200-400 mesh.

[0043] Glaze formula: feldspar 20-40, coke gem 10-20, cooked talc 10-20, Datong soil 5-10, stalactite 1-2, quartz 1-3, barium titanate 1-2, bismuth oxide 1-2 , improver 0.1-0.5; the improver is a mixture of yttrium oxide, cerium oxide and samarium oxide in a weight ratio of 1:1:1.

[0044] 3) Isostatic pressing: isostatic pressing under the condition of vacuum degree of 0.07-0.09MPa;

[0045] 4) drying and trimming;

[0046] 5) Glazing inside and outside the green body;

Abstract

Belonging to the technical field of industrial ceramics, the invention relates to an easy-to-clean industrial ceramic and a preparation method thereof. The easy-to-clean industrial ceramic comprises a green body and a glaze surface covering the green body. The easy-to-clean industrial ceramic is characterized in that the glaze surface is fritted glaze made from the following raw materials by weight part: 20-40 of feldspar, 10-20 of flint clay, 10-20 of cooked talc, 5-10 of Datong soil, 1-2 of stalactite, 1-3 of quartz, 1-2 of barium titanate, 1-2 of bismuth oxide, and 0.1-0.5 of an improver; the improver is a mixture of yttrium oxide, cerium oxide and samarium oxide in a weight ratio of 1:1:1; or the improver is a mixture of cerium oxide, samarium oxide and gadolinium in a weight ratio of 1:1:1. The green body is prepared from the following raw materials: 30-35 parts of coal gangue, 17-22 parts of feldspar, 8-12 parts of quartz, 8-13 parts of calcined Datong soil, 10 parts of calcined high alumina bauxite, 5-10 parts of Jiexiu soil, 5-10 parts of zimujie clay, 1-3 parts of Suzhou clay, 5-8 parts of Fangzi clay, and 1-3 parts of cooked talc. According to the invention, a layer of ceramic glaze is attached to the industrial ceramic surface, and the preparation process is optimized so as to obtain industrial ceramic with a super smooth surface, and the industrial ceramic has excellent antifouling and easy-to-clean performance.

Description

technical field [0001] The invention relates to the technical field of industrial ceramics, in particular to an easy-to-clean industrial porcelain and its preparation method. Background technique [0002] Industrial ceramics, that is, ceramics for industrial production and industrial products, mainly utilize their characteristics of acid and alkali resistance and high wear resistance coefficient in the prior art. [0003] In the industrial porcelain used in the chemical, rubber or plastic industries, sometimes the industrial porcelain will directly contact with various chemical raw materials, rubber solution or PVC solution, and this kind of industrial porcelain has the problem of difficulty in cleaning. [0004] The reason why the ceramic surface is contaminated with dirt is: on the microstructure, there are unevenness and tiny pinholes or pores on the ceramic surface. During the use of ceramics, it is easy to come into contact with pollutants in the environment. Under the...
