Description

technical field

[0001] The invention discloses a modification method of natural bentonite, in particular refers to the preparation of modified bentonite with low quartz and cristobalite content and high viscosity by using natural bentonite minerals as raw materials and the preparation method thereof, which belongs to the category of new material technology. Background technique

[0002] Bentonite, also known as bentonite, bentonite, montmorillonite, smectite, bentonite, Guanyin clay, etc., is a widely distributed non-metallic clay mineral.

[0003] The properties and characteristics of bentonite are mainly determined by the structure of montmorillonite contained in it. Montmorillonite is a two-dimensional planar layered structure of aluminosilicate, which consists of two layers of silicon-oxygen tetrahedral sheets and one layer of aluminum-oxygen (hydroxyl) octahedral sheets sandwiched between them. Its general structural formula is: Al 2 o 3 4SiO2 2 ·nH 2 O, (n>2); ...
