Abstract

The invention discloses a composite ceramic toughened ceramic brick with a humidity adjusting function and a production method thereof. The ceramic brick comprises a surface material layer and a bottom material layer from top to bottom, wherein the surface material layer is prepared from high ignition lost plastic mud, diatomaceous shale, vermiculite, bauxite, attapulgite and micro-alumina whisker; the bottom material is formed by a ceramic low-temperature powder having firing shrinkage coefficient which is basically accordant with that of the surface material. According to the production method, the ceramic brick is prepared by firing at low temperature after molding, a glass phase is not generated in the surface material layer, pores are not blocked, fine cracks are generated on submicron moisture-absorption pores since expansion coefficients among the raw materials are not matched so as to reinforce the moisture absorption and release capability of the product; and the strength of the brick can be guaranteed after the bottom material layer is sintered. The method disclosed by the invention can be used for solving the problem of low strength of an existing humidity adjusting material ceramic brick.

Description

technical field [0001] The invention belongs to the field of preparation of architectural ceramic products, and in particular relates to a multiphase ceramic toughened ceramic brick with the function of regulating humidity and a production method thereof. Background technique [0002] The relative humidity of the air is a physical quantity indicating the amount of water vapor in the air, that is, the degree of dryness and humidity. It is an important parameter to measure the indoor environment. It is of great significance to human health, indoor air quality and the storage of items. Humidity affects human health, and has serious hazards to the preservation of items, the life of instruments, etc.; the harm is more serious when the humidity changes alternately from too high (low) to too low (high). The national "Air Quality Standard" stipulates the standard value of indoor relative humidity, which is 40% to 60% for air-conditioned rooms in summer and 30% to 60% for heated room...
