Description
Technical field
The present invention relates to a kind of novel preparation method for bentonite, particularly a kind of preparation method of organic modified bentonite.
Background technology
Wilkinite has another name called otaylite, amargosite, polynite etc., is by tuff or other volcanic rock alteration and a kind of pillared layered compound of forming under the effect of alkaline water.Its main component is montmorillonite, wherein contains SiO

+Deng replacement.When the positively charged ion in octahedron, tetrahedron is replaced at a low price, make primary structure increase the negative charge of equivalent, the compensation of interlayer Liquidity limit is arranged.Form electric dipole between the positively charged ion between montmorillonite layer and crystal skeleton, a little less than adding that between the montmorillonite crystal layer, bonding force, can adsorb polar water molecules, according to cation type and relative humidity, interlayer can adsorb the water molecules of one deck or two layers.In addition, also can adsorb certain water molecules at the montmorillonite grain surface.Water of constitution is present in lattice with OH base form.
Wilkinite is as a kind of important nonmetallic minerals, and reserves are large, have a very wide distribution.There are the U.S., China, Russia, Italy, Greece, India and Germany in bentonitic major country of production.At present, no matter be petroleum drilling or geological prospecting drilling well, all adopt in a large number the drilling mud of wilkinite preparation.Wilkinite can improve mud yield and drilling benefit greatly as the synergistic agent that adds, and is conducive to creep into various complicated geologicals, and in the prevention well, accident occurs.Because the development of China Petroleum increases with the wilkinite demand year by year to drilling fluid, wilkinite has a extensive future aspect petroleum drilling.
Drilling mud plays an important role in drilling well, and bore slurry and be divided into two classes: a class is mud, and carrier is mainly water, and wilkinite is thickening material; Another kind of is oil-base mud, and carrier is mainly crude oil, diesel oil and white oil.Due to oil loving requirement, mainly adopt organic bentonite.
Be mainly to utilize cats product as properties-correcting agent to bentonitic research and production method both at home and abroad at present, by wet method, dry method or pre-gel, sodium bentonite carried out intercalation ion-exchange.Also there is research to coordinate nonionogenic tenside or anion surfactant as properties-correcting agent cats product.Nonionogenic tenside, alkylamine, amino acid, coupling agent or alcohols etc. also are used to bentonitic intercalation or finishing organises wilkinite in addition.
Bentonite use be all generally with the basis that is mixed into of organic substance, therefore prepared organobentonite lamella organic decoration more abundant, sheet interlayer spacing is larger, illustrate that between lamella, reactive force is less, arrangement is more random, just better with the consistency of organic substance, the bentonite application performance is just better.
Therefore, provide a kind of technique simple, the organic modified bentonite composite manufacture method that production cost is low just becomes the technical barrier that this technical field is badly in need of solution.
Summary of the invention
The purpose of this invention is to provide a kind of technique simple, the preparation method of the organic modified bentonite that production cost is low.
Above-mentioned purpose of the present invention reaches by the following technical programs:
A kind of preparation method of organic modified bentonite comprises the steps:
(1) sodium bentonite is added entry and stir, get sodium bentonite suspension;
(2) at room temperature, cetyl trimethylammonium bromide is water-soluble, and then add sorbitan monooleate to stir, get milk sap;
(3) step (1) gained sodium bentonite suspension is mixed with step (2) gained milk sap, carry out the constant temperature oscillation reaction, be cooled to room temperature by after centrifugal, washing, drying, pulverizing, crossing mesh sieve, obtain product.
With in the described sodium bentonite suspension of step (1) take every kilogram of sodium bentonite as benchmark, described in step (2), the cetyl trimethylammonium bromide add-on is 0.5 ~ 2.5mol, the add-on of described sorbitan monooleate is 0.5 ~ 2.5mol.
In step (1), the weight ratio of described sodium bentonite and water is (1 ~ 5): (99 ~ 95), namely 1: 99 ~ 5: 95; The preparation method of described sodium bentonite suspension is: adopting natural sodium bentonite or artificial sodium bentonite is raw material, with obtaining after water-dispersion; After also used water is disperseed, then after removing precipitated impurities, centrifugation obtains.Suspension concentration is about 1 ~ 5wt%.
In step (2), add sorbitan monooleate to stir 1.0 ~ 2.0 hours, get milk sap.
In step (3), the temperature of described constant temperature oscillation reaction is 50 ℃ ~ 90 ℃, and the time is 4 ~ 12 hours; Described drying temperature is 60 ℃ ~ 105 ℃; The described order number of crossing mesh sieve is 200 orders.
The present invention is directed to the problem that known technology exists, provide a kind of sodium bentonite suspension that utilizes to be raw material, prepare the bentonite method by cetyl trimethylammonium bromide and sorbitan monooleate absorption intercalation.Can obtain quality products, can realize that again technique is simple, reduce production costs.
The present invention compared to the prior art, significantly characteristics are in sodium bentonite suspension, add the milk sap of cats product and nonionogenic tenside.As everyone knows, sodium bentonite is subjected to aquation can act on can be in water stable suspended dispersed, and then delamination, and on the laminate of its delamination the time with negative electricity.Positively charged vesica in the milk sap of the formation of cats product and nonionogenic tenside will be because of electrostatic attraction and Van der Waals force and is adsorbed on electronegative wilkinite laminate.Because its bonding force is stronger, can not washed off in the process of centrifugation washing.In the process of drying, because water molecules between laminate volatilizees gradually, destroyed original balance and caused vesica to break, thereby made cats product and nonionogenic tenside arrange expansion between bentonite bed.At this moment, at wilkinite surface and interlayer, nonionogenic tenside also is attracted to wilkinite surface and interlayer because of Van der Waals force and hydrogen bond action to cats product because of chemisorption.This legal system that Here it is has the bentonitic principle of machine.
The present invention will be further described below by the drawings and the specific embodiments, but and do not mean that limiting the scope of the invention.
