Background technology
Bentonite is also referred to as montmorillonite, is the minerals being mainly made of montmorillonite.The main component of montmorillonite is comprehensive silicon
Hydrochlorate.The minerals be natural nano grade interlamellar spacing inorganic matter, about tens nanometers of piece interlamellar spacing, have special water imbibition,
Hydroplasticity, caking property and stronger ion exchangeable etc. are that current application range is most wide, the higher clay mineral of economic value
One of, it has been widely used in the every field such as metallurgy, machinery, oil, chemical industry, high molecular material and environmental protection.But
Due to the surface active of bentonite micro mist, there are problems for compatibility and dispersion in polymer matrix.So needing to swollen
Profit soil is modified.
At present much about to bentonite modified research, if the patent of invention of Patent No. CN102660159A is in 2012
The modified superfine bentonite of a kind of modified superfine preparation method for bentonite, preparation and its application, use disclosed on September 12,
Borate ester modifying agent solves the compatibility and dispersion problem of Ultra-fine Bentonite and high molecular material.
During to alta-mud modification, the preparation of modifying agent and modifying agent are even more important with bentonitic react,
It is prepared with water and chloromethanes currently, modifying agent mostly uses tertiary amine, for the effect of modifying agent, using two different tertiary amines
Mixing, it is also high to the equipment requirement that modifying agent preparation is used because the toughness of tertiary amine is high, due to stirring in preparation process
It the factors such as mixes, often leads to can't meet the quality requirement.
In process, bentonite needs to crush, is levigate, quality higher bentonite is made, meets the need of purposes
It wants, currently, it is undesirable to bentonitic crushing effect, as the Chinese utility model patent of Publication No. 202096975U discloses
A kind of gear crusher for bentonite, crushing effect is poor, less efficient so that bentonitic the production cost increases.
