Kaolinite intercalation method

Abstract

A collyrium intercalation process comprises the steps of, dissolving the organic micromolecules containing amino, amido, hydroxy, carboxyl or sulfonyl active functional groups into distilled water to prepare solution of 5-16.7mol / L, disintegrating the collyrium and passing through 100 mesh sieves, charging into the solution by the mass ratio of 1:15-30, obtaining the miscible liquid by uniform dispersion, placing the generating head of the multiple frequency acoustochemiscal generator into the miscible liquid, agitating and carrying out acoustochemical intercalation, filtering the solution and drying in the open.

Description

technical field

[0001] The invention relates to a kaolinite intercalation method. Background technique

[0002] The organic compound of kaolinite formed by inserting organic molecules between kaolinite layers is a new type of mineral material. It has broad application prospects in the fields of functional ceramic materials, environmental engineering materials, nanocomposites, catalysts, and selective adsorbents. At present, the research on the intercalation clay reaction at home and abroad mainly focuses on the intercalation of montmorillonite and kaolinite, and the intercalation of montmorillonite is relatively easy. However, kaolinite is a typical 1:1 layered silicate, which does not contain exchangeable cations between layers, and is considered to be a non-swellable clay mineral, so the intercalation of kaolinite is relatively difficult. Intercalation methods mainly include solution intercalation and melt intercalation. Solution intercalation is to insert organic molec...
