Abstract
The present invention relates to nano technology and is especially the nano size montmorillonoid and its preparation. The nano size montmorillonoid has great specific surface area, high activity, high dispersivity, and the general properties of common nano material, such as small size effect, surface effect and optical effect.
Description
The invention belongs to field of nanometer technology, relate more specifically to nano size montmorillonoid and preparation method thereof.Be applicable to the field that all use nano size montmorillonoid and notion thereof.It is characterized in that having high specific surface area, high reactivity and polymolecularity, possess the general character of nano material, as small-size effect, surface effects, optical effect.
At present, the polynite development and use are confined to common stopping composition more, are applied to field of nanometer technology in recent years and also just are confined to its interlayer structure, are intercalation processing, are purpose to increase interlamellar spacing.
The intent of the present invention is the natural mineral polynite after purification processes, obtains the stabilized nano size montmorillonoid through physics shearing or milled processed again.
Below in conjunction with embodiment the present invention is described.It should be noted that these embodiment only are part embodiments of the present invention, is not restriction use range of the present invention:
Embodiment 1: gets natural montmorillonite 50g, adds water 500mL, dissolve back elimination impurity, and, add 31% hydrochloric acid 10mL and carry out acidification.50 ℃ of souring temperatures.Acidificatoin time 0.5 hour, the polynite after the acidifying water repeatedly clean to pH value and approach 5, transfer to pH value with alkali and approach 7, obtain nano size montmorillonoid through stirring to shear, and detect median size by analysis less than 20 nanometers.
Embodiment 2: get natural montmorillonite 50g, add water 500mL, after dissolving, add 31% hydrochloric acid 10mL and carry out acidification.30 ℃ of souring temperatures.Acidificatoin time 1 hour, the polynite elimination impurity after the acidifying, water cleans to pH value and approaches 5 repeatedly, transfers to pH value with alkali and approaches 7, obtains nano size montmorillonoid through milled processed, detects median size by analysis less than 20 nanometers.
Embodiment 3: get natural montmorillonite 50g, add water 300mL, after dissolving, add 5g yellow soda ash and carry out ion exchange treatment.30 ℃ of temperature, 24 hours time, the polynite elimination impurity after the processing obtains nano size montmorillonoid through shear agitation, detects median size by analysis less than 30 nanometers.
Embodiment 4: get natural montmorillonite 50g, add water 1000mL, after dissolving, add the 5g sodium bicarbonate and carry out ion exchange treatment.20 ℃ of temperature, 48 hours time, the polynite elimination impurity after the processing obtains nano size montmorillonoid through shear agitation, detects median size by analysis less than 30 nanometers.
