ZHANG MIN / DENG JIANGUO / ZHANG JUNYING

The invention belongs to the technical field of ceramics, particularly relates to an acid-resistant, high-temperature-resistant and high-pressure-resistant earthenware brick and a preparation method thereof, and aims at solving the problems of poor acid resistance, high temperature resistance and high pressure resistance in the prior art. The ceramic brick is prepared from the following raw materials in percentage by weight: 65%-75% of superfine clay, 10%-15% of flint clay, 2%-5% of aluminosilicate, 3%-6% of magnesium silicate, 1%-5% of a ceramic reinforcing agent and 5%-7% of an additive, and the superfine clay is prepared from the following raw materials: clay, modified limestone powder, lauryl sodium sulfate, aluminate and polyoxyethylene ether. Through the materials such as the superfine argil, the flint clay, the aluminosilicate, the magnesium silicate, the ceramic reinforcing agent and the additive, the mechanical performance of the earthenware brick can be effectively ensured, the acid resistance, the high temperature resistance and the high pressure resistance of the earthenware brick are enhanced, under the conditions, the earthenware brick is not prone to cracking, cracking, cracking and the like, and the performance of the earthenware brick is ensured.
