Abstract

The invention provides a ceramic material with a multi-stage duct structure and a manufacture method thereof. The ceramic material is characterized by being provided with a plurality of macropores with millimeter grade, tens of middle pores with millimeter grade exist on the walls of the macropores, micropores with sizes less than microns exist on the walls of the middle pores. The ceramic material is manufactured by using 10-50 percent by mass of waste and 20-60 percent by mass of natural porous mineral and matching with 10-30 percent by mass of clay through the steps of adding water for mixing, forming, drying, preheating and sintering at a temperature of 1000-1200 DEG C, wherein the waste can be expanded at high temperature or has large ignition lost and easy decomposition and volatilization. The ceramic material has excellent water-absorbing and water-retaining properties, better water permeability, excellent absorption and filtration and light weight, and can be used as a water-absorbing material, a water-retaining material, a water permeating material, a sound insulating material, a heat insulating material, an indoor deodorizing material, an absorbing material, a filtering material and the like to be widely applied to various fields.

Description

technical field [0001] The invention relates to a porous ceramic material and a manufacturing method thereof, in particular to a ceramic material with a multi-level pore structure made from waste as the main raw material and a manufacturing method thereof. Background technique [0002] Porous ceramics, as the name implies, are ceramic materials containing a large number of pores. Generally, the volume fraction of pores in the porous ceramic material is between 20% and 95%. Due to its unique porous structure, porous ceramics have the characteristics of low thermal conductivity, small bulk density, high specific surface area, and surface structure with unique physical and chemical properties. Advanced features, has been widely used in environmental protection, energy saving, chemical industry, petroleum, smelting, food, pharmaceutical, biomedical and other fields. [0003] At present, there are mainly the following methods for preparing porous ceramics: [0004] (1) Solid-s...
