Abstract

The present invention provides a kind of high absorption capacity sodium base bentonite preparation methods, and after raw ore bentonite is first crushed homogenizing processing, grain size screening obtains original ore soil, then the coal dust of original ore soil quality 0.5 5% is added in original ore soil, is sufficiently mixed；Then the agent of receiving of original ore soil quality 10 15% is added after progress low temperature distillation, high-temperature vapor distillation successively, is put into cooled to room temperature under room temperature, carries out ripening, is dried, obtain finished product.Adsorption capacity of the present invention is strong, and preparation method is simple, is suitble to industrialized production.

Description

A kind of high absorption capacity sodium base bentonite preparation method
Technical field
The present invention relates to bentonite preparation field, specifically a kind of high absorption capacity sodium base bentonite preparation method.
Background technology
Bentonite ore is the mineral products of one kind of multiple purposes, and quality and application field depend primarily on wherein smectite content With attribute type and its crystal chemistry characteristic.Thus, utilization must be different because of mine, different because of effect.Such as produce activity Carclazyte, calcium base turn sodium base, for the drilling well slip casting of oil drilling, instead of the slurry that starch is used to spin, print and dye, with interior on building materials Exterior coating prepares organobentonite, with bentonite synthesis 4A zeolites, production white carbon etc..
Sodium bentonite is divided according to montmorillonite the exchangeable cationic type between layer type, content：Alkaline coefficient be more than or It is sodium bentonite equal to 1, is calcium-base bentonite less than 1.
The sodium base bentonite adsorption capacity prepared under technology room temperature at present is nothing like natural sodium bentonite.
Invention content
The present invention in order to solve problems in the prior art, provides a kind of high absorption capacity sodium base bentonite preparation method, Adsorption capacity is strong, and preparation method is simple, is suitble to industrialized production.
The present invention includes the following steps：
1）After raw ore bentonite is crushed homogenizing processing, grain size screening obtains original ore soil；
2）The coal dust of original ore soil quality 0.5-5% is added in original ore soil, is sufficiently mixed；
3）Mixed-powder is put into gas retort and carries out low temperature distillation, pyrolysis temperature is no more than 300 DEG C；
4）High-temperature steam is passed through in mixture after destructive distillation, vapor (steam) temperature is more than 500 DEG C, continues 3-6min；
5）The agent of receiving of original ore soil quality 10-15% is added, is put into cooled to room temperature under room temperature, carries out ripening, drying Processing, obtains finished product.
It is further improved, the agent of receiving is sodium carbonate, sodium metasilicate, sodium fluoride, sodium oxalate, sodium acetate, phosphoric acid class sodium It is one or more in salt, Sodium Polyacrylate, sodium hydroxide, sodium chloride, sodium thiosulfate and sodium cellulosate.
Advantageous effect of the present invention is：Adsorption capacity is strong, and preparation method is simple, is suitble to industrialized production.
Specific implementation mode
The invention will be further described below.
The present invention includes the following steps：
1）After raw ore bentonite is crushed homogenizing processing, grain size screening obtains original ore soil；
2）The coal dust of original ore soil quality 0.5-5% is added in original ore soil, is sufficiently mixed；
3）Mixed-powder is put into gas retort and carries out low temperature distillation, pyrolysis temperature is no more than 300 DEG C；
4）High-temperature steam is passed through in mixture after destructive distillation, vapor (steam) temperature is more than 500 DEG C, continues 3-6min；
5）The agent of receiving of original ore soil quality 10-15% is added, is put into cooled to room temperature under room temperature, carries out ripening, drying Processing, obtains finished product.
It is further improved, the agent of receiving is sodium carbonate, sodium metasilicate, sodium fluoride, sodium oxalate, sodium acetate, phosphoric acid class sodium It is one or more in salt, Sodium Polyacrylate, sodium hydroxide, sodium chloride, sodium thiosulfate and sodium cellulosate.
There are many concrete application approach of the present invention, the above is only a preferred embodiment of the present invention, it is noted that for For those skilled in the art, without departing from the principle of the present invention, it can also make several improvements, this A little improve also should be regarded as protection scope of the present invention.
