A kind of daily-use ceramic raw material and preparation method thereof

Abstract

The invention discloses a daily-use ceramic raw material and a preparation method thereof, and belongs to the technical field of ceramic production. The problems that an existing ceramic raw material is high in cost, low in yield and large in energy consumption are solved. The ceramic raw material is prepared from, by weight, 40-60 parts of North Korea kaolinite rock, 1-5 parts of high-alumina bauxite, 10-20 parts of quartz sand, 10-20 parts of Guangxi white mud, 20-30 parts of Guangdong black mud, 5-10 parts of bentonite, 50-60 parts of water and 0.5-0.8 part of grinding aid. The preparation method comprises the steps that the North Korea kaolinite rock is pretreated to be particles of 0.2 cm to 0.5 cm, all the raw materials are mixed and then ground through a wet ball mill, the ground materials are sieved, subjected to high-intensity magnetic deironing through a high-intensity vibration sieve and then filtered to a slurry containing pool, stirring and ageing are conducted, the materials are sent to a mud press to be subjected to filter pressing to obtain a mud cake, the mud cake is dried and scattered, and the daily-use ceramic raw material is obtained. The daily-use ceramic raw material can be doped in ordinary ceramic raw materials to improve the whiteness of a finished product.

Description

technical field [0001] The invention relates to a daily-use ceramic raw material and a preparation method thereof, belonging to the technical field of ceramic production. Background technique [0002] China is an ancient country of porcelain civilization and a major producer of ceramics in the contemporary world. The quality and grade requirements of products are getting higher and higher. In order to cope with the increasingly severe market competition situation, the ceramic industry should continuously improve product quality and grade. [0003] The existing high-end daily-use ceramic raw materials are usually processed from high-quality raw ore, and the cost is relatively high. The whiteness of raw materials is generally about 82%, the dry flexural strength is about 3.5MPa, and the whiteness of bone china raw materials is generally about 88%. The dry flexural strength is about 4.5 MPa. The quality of bone china is fine and transparent, the shape is beautiful and elegant,...

Problems solved by technology

[0003] The existing high-end daily-use ceramic raw materials are usually processed from high-quality raw ore, and the cost is relatively high. The whiteness of raw materials is generally about 82%, the dry flexural strength is about 3.5MPa, and the whiteness of bone china raw materials is generally about 88%. The dry flexural strength is about 4.5 MPa. The quality of bone china is fine and transparent, the shape is beautiful and elegant, and the grade is high. It is currently the only high-grade porcelain recognized in the world. However, the raw material cost of bone china is relatively high, and the current market price is 2900 -3500 yuan / ton, and the processing of bone china products is difficult and the scrap rate is high
