Alkaline calcium bentonite and its preparation method

TLDR
In this article, an alkaline calcium bentonite with anion exchanging function was made using active carclazyte and calcium oxide as raw material, which can react with organic acid to prepare composite layered nanometer material which can be applied in the coating, plastic and new adsorptive material domain.
Abstract
The invention discloses an alkaline calcium bentonite and making method, which comprises the following steps: adapting active carclazyte and calcium oxide as raw material; mixing the raw material evenly; reacting the calcium oxide and water to produce calcium hydroxide; diffusing the calcium hydroxide in the active carclazyte layers; reacting one of two oxyhydrogen base with hydrogen of active carclazyte to produce the alkaline calcium bentonite with anion exchanging function. The invention can react with organic acid to prepare composite layered nanometer material, which can be applied in the coating, plastic and new adsorptive material domain.
