Method for preparing porous charcoal-ceramic composite material

Abstract

The invention relates to a preparation method of lacunaris carbon matrix-ceramics composite material, which is characterized by: taking the waste of processed bamboo filings as raw material, adopting phosphoric acid to infuse, dry, bake, grind and sift out to obtain active bamboo charcoal powder; taking silica sol and trihydrate alumina to prepare antioxidant collosol; taking bamboo charcoal power and kaoline which are mixed with SOi2-A12O3 collosol and millet to blend into a mud pie to form dry body which is imbedded into a chark and is put in a ceramic crucible. The carbon matrix-ceramics composite material is obtained by being baked at the temperature of 900 to 1100 DEG C.

Description

A kind of preparation method of porous carbon matrix-ceramic composite material technical field The invention belongs to the technical field of manufacturing inorganic non-metallic materials, and in particular relates to a preparation method of a porous carbon base-ceramic composite material. Background technique With the continuous deepening of my country's reform and opening up, China's economy has maintained a momentum of rapid growth, but at the same time, it has brought serious environmental problems, such as air pollution and water pollution. In the study of solving environmental pollution problems, activated carbon has been widely used because of its ability to adsorb harmful substances. Due to the existence of a large number of micropores in activated bamboo charcoal, it has a huge specific surface area (the specific surface area is 200-300m2 / g). Effect. How to utilize the excellent characteristics of activated bamboo charcoal to develop a new porous material th...
