Abstract

The invention discloses a constructional energy-saving ceramic brick with a passive humidity adjusting function and a production method thereof. The ceramic brick contains humidity-adjustable submicron holes which are left after sintering of high-temperature-sintered plastic-lost soil, diatomaceous shale, vermiculite, bauxite and attapulgite; the ceramic brick is prepared by sintering at low temperature, wherein a glass phase is not generated and holes are not plugged; and due to the mismatches of expansion coefficients of various raw materials, small microcracks are produced on the submicron moisture absorption holes, so moisture absorption and deabsorption abilities of the ceramic brick are enhanced. The production method provided by the invention overcomes the problems of small moisture deabsorption amount, slow moisture deabsorption, small moisture capacity, complicated manufacturing process and high production cost of conventional humidity adjusting materials.

Description

technical field [0001] The invention belongs to the field of preparation of building ceramic products, and in particular relates to a building energy-saving passive humidity-regulating functional ceramic brick 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 rooms in winter. ...
