Porous modified bentonite with foaming effect and preparation method thereof

Abstract

The invention discloses porous modified bentonite with foaming effect. The porous modified bentonite is characterized by being prepared from the following raw materials by weight: 85 to 90 parts of calcium bentonite, 1 to 2 parts of octadecyl trimethyl ammonium chloride, 1 to 2 parts of ammonium bicarbonate, 3 to 5 parts of activated carbon powder, 2 to 3 parts of sodium silicate, 0.8 to 1.3 parts of aminopropyltriethoxysilane, 2 to 2.5 parts of carboxymethyl cellulose, 5 to 7 parts of phenolic resin powder, 2 to 3 parts of crushed phoenix tree leaves and 3 to 4 parts of modified diatomite. According to the invention, a formula is reasonable; since bentonite is modified by adding foaming matters like ammonium bicarbonate and activated carbon powder and surfactants like octadecyl trimethyl ammonium chloride, the modified bentonite has porosity, so good adsorption effect is obtained; moreover, through good dispersion of the modified bentonite and the crushed phoenix tree leaves, the porous modified bentonite in the invention is porous and uniform in dispersion and is applicable as a water purification adsorbent, etc.
