Embodiment Construction

[0019] A method for preparing ceramics, comprising the steps of:

[0020] (1) Take materials according to the following weight (kg): waste white porcelain powder 15, quartz powder 35, feldspar powder 10, alumina 5, diatomite 35, kaolin 15, stearic acid 0.2, modified polycarboxylate water reducing Agent 2;

[0021] (2) Mix the above components except the modified polycarboxylate water reducer to make china clay, then add appropriate amount of water to disperse the china clay into a dispersion suspension with a concentration of 40%, ball mill for 2 hours, and after drying, add Modified polycarboxylate water reducer, add appropriate amount of water to make ceramic blank;

[0022] (3) Prepare the glaze by conventional technology;

[0023] (4) After the blank is formed, it can be glazed and colored, fired at high temperature, cooled and formed.

[0024] The preparation method of the modified polycarboxylate water reducer is as follows: put the papermaking waste white mud in the ...

Abstract

The invention provides a preparation method of ceramic, which includes the following steps: 1) according to weight part ratio, preparing raw materials, mixing the raw materials, except a modified polycarboxylate water reducing agent, to prepare porcelain clay and adding a proper amount of water to disperse the porcelain clay into a dispersion suspension liquid being 15-40% in concentration, and ball-milling the dispersion suspension liquid for 1-2 h; 2) drying the dispersion suspension liquid and adding the modified polycarboxylate water reducing agent and a proper amount of water to produce a ceramic green body; 3) preparing a glaze according to a conventional process; and 4) after the green body is shaped, glazing and coloring the green body, sintering the green body at high temperature and cooling and shaping the green body to obtain a ceramic material. The formula of the porcelain clay in the ceramic material has abundant raw materials and low cost. Compared with ceramic mud in the prior art, the porcelain clay is improved in plasticity, so that yield of the ceramic green body during the high temperature sintering is increased.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a method for preparing ceramics. Background technique [0002] The use of ceramic dispersant (water reducer) in ceramic production can not only make ceramic slurry have good fluidity, but also reduce its moisture content, improve the performance of ceramics, and have the effect of improving product performance and energy saving and emission reduction. Ceramic water reducer (also known as dispersant) is a kind of ceramic additive, its main function is to destroy the flocculation structure of ceramic slurry particles, so that the slurry still has good dispersibility and low the viscosity. Play a role in energy saving and consumption reduction in the ceramic production process. Ceramic superplasticizers can be widely used in ceramic production processes such as mud making, pulp refining, and glaze making in the ceramic industry. The use of superplasticizers with excellent performance in c...
