Ceramic product prepared from waste ceramic and preparation method thereof

Abstract

The invention relates to a ceramic product prepared from waste ceramic and a preparation method thereof. The blank formula of the ceramic product comprises the following components in part by weight: 32-36 parts of waste ceramic powder, 25-28 parts of kaolin, 15-22 parts of plastic clay and 17-25 parts of feldspar. The basic glaze formula of the ceramic product comprises the following components in part by weight: 30-35 parts of miniumite, 8-12 parts of limestone, 20-30 parts of feldspar, 8-14 parts of clay and 20-25 parts of quartz. A right amount of coloring metal compounds and / or coloring materials are added into the basic glaze. Compared with the prior art, a large amount of waste ceramic powder is used for replacing the traditional ceramic raw material for the basic glaze formula, and the technological difficulties of waste ceramic powder compounding, grain composition, sintering, decoration and the like are overcome. Not only is the waste changed into the valuable and a large amount of waste ceramic products are fully utilized, but also the sintering temperature of the ceramic product can be lowered, the energy consumption is reduced, the production cost of ceramic manufacturers is lowered, and the market competitiveness of the product is increased.

Description

technical field

[0001] The invention relates to the field of ceramic manufacturing, in particular to a ceramic product made from waste porcelain and a preparation method thereof. Background technique

[0002] At present, domestic recycling of ceramic waste is limited to a small amount of decorative additives used in buildings, and some ceramic manufacturers have introduced a small amount of glaze into the glaze to improve the bonding performance of the body and glaze. There is no research and development of related technologies for mass recycling of waste porcelain.

[0003] For this reason, the applicant considers using a large amount of waste porcelain as the raw material of the blank. However, to use the waste porcelain as the raw material of the blank to produce ceramic products that meet the quality requirements, many problems need to be solved: such as the proportion of waste porcelain in the blank, How to choose the other components of the blank to match the waste por...

[0030] In parts by weight, the blank formula is as follows: 34 parts of waste porcelain powder; 28 parts of kaolin; 18 parts of plastic clay; 20 parts of feldspar;

[0031] In parts by weight, the formula of the basic glaze is as follows: 32 parts of red lead; 10 parts of limestone; 25 parts of feldspar; 11 parts of clay; 22 parts of quartz.

[0032] Add appropriate amount of artificial synthetic pigments to the basic glaze formula, and carry out the steps of blank batching, ball milling, drying, granulation, blank molding, biscuit firing, decoration and glaze firing to obtain finished products. The main technical indicators of the obtained products are as follows:

[0033] Glaze linear expansion coefficient: 5.8×10 -6 / °C;

[0034] Blank glaze bonding: good bonding;

[0035] Glaze gloss: good;

[0036] Thermal stability: 200-20 ℃ water heat exchange once without cracking;

[0037] Glazed effect: It has high artistic quality, and the transition between colors is natural. ...
