Abstract

The invention discloses a fireproof pot clay, and a preparation method thereof. The fireproof pot clay comprises, by mass, 10 to 15 parts of iolite, 15 to 20 parts of petalite, 7.5 to 10 parts of black stone powder, 35 to 50 parts of black slime, 2.5 to 3.5 parts of raw talcum powder, 5 to 7 parts of spodumene, and 0.4 to 0.6 part of ACUMER 9300. The fireproof pot clay is subjected to high temperature sintering, obtained blank is white, color is bright, the heatproof index is higher than that of common fireproof pot clay, 300 to 400 DEG C quenching-rapid heating test requirements are satisfied, and no cracking is caused.

Description

technical field [0001] The invention relates to a refractory pot mud and a preparation method thereof. Background technique [0002] At present, refractory pot mud is a kind of heat-resistant soil with a white green body after firing, which can be used as refractory pot pot and porcelain for microwave ovens without bursting, but the plasticity of refractory pot mud on the existing market is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a kind of refractory clay pot, which is fired at high temperature, the green body is white, and the matching color is bright. 400°C rapid cooling and rapid heating performance test, no bursting. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is: a kind of refractory pot mud, the mass parts of the component that its used mud material contains and each ...
