Abstract

The present invention relates to nano material technology, especially, hydrophilic nano montmorillonite and its preparation. The hydrochloric acid solution of organic intercalating agent is added to the water solution of sodium-base montmorillonite with charge exchange amount of 80-100 mmol / 100 g to prepare organic montmorillonite slurry with the molar charge exchange amount ratio between the organic intercalating agent and montmorillonite being 1-2. Modifiying agent in the molar amount of 1-4 time that of the added organic intercalating agent is added to the slurry via stirring at 40-80 deg.c for 3-6 hr to obtain the hydrophilic nano montmorillonite comprising montmorillonite and organic intercalating agent in the weight ratio of 1-10.

Description

technical field

[0001] The invention belongs to the field of nanometer materials, in particular to hydrophilic nanometer montmorillonite and a preparation method thereof. Background technique

[0002] Nanotechnology has made considerable progress since its appearance in the 1980s, especially nano-montmorillonite has been widely used in nanomaterials. But almost all reports about nano-montmorillonite are about the application of nano-montmorillonite in engineering plastics, such as patent application number 96105362 "a polyamide / clay nanocomposite and its preparation method"; patent application number 98103038 "Polystyrene / clay nanocomposite material and its preparation method"; patent application No. 98117488 "polypropylene / montmorillonite intercalation composite material and its preparation method" are all about the application of montmorillonite in nanomaterials Discussions have been carried out, and it is described in detail in these patent applica...
