Background technology
One, the realization means of the organic clay of big interplanar distance
Organic clay industrially can be widely applied to petroleum drilling fluid, coating, polymer nanocomposites and other field of fine chemical.Through the clay of organic modification, its original interplanar distance becomes big.In the field such as drilling fluid, rheological agent, the interplanar distance positive correlation of the suspension of colloidal dispersion, rheological characteristic and organic clay.In polymer composites field, the interplanar distance of organic clay is more big, and clay-phase is more easily peeled off slabbing and is dispersed among polymeric matrix, thus improving material property.
The component of organic clay is generally made up of raw clay, organic modifiers, sometimes also needs to add some auxiliary agents in component, to promote to organise reaction, or improves application performance.
The raw material of existing organic clay is based on swelling great soil group.Bentonitic it is mainly composed of montmorillonite.According to cationic dissimilar between montmorillonite layer, its interplanar distance d [001] is generally 1.2～1.5nm；If without interlayer cation, d [001] is then 0.96nm.Bentonite d [001] can reach more than 2nm.
The approach increasing interplanar distance has two.Article one, approach is the suitable organic modifiers selecting molecular weight bigger, as double long-chain alkyl quaternary ammonium salt is provided that bigger molecular weight, regrettably, in clay mineral reserve known in the world, only minority mineral reserve are suitable for double long-chain alkyl quaternary ammonium salt organically-modified, and it is organically-modified that major part bentonite is not suitable for double long-chain alkyl quaternary ammonium salt；Another approach is the clay selecting initial interplanar distance bigger, the d [001] of rectorite is 2.2～2.7nm, being one of clay mineral that in known various clays, original interplanar distance is maximum, preparing organic clay with it for raw material is the effective way improving interplanar distance.
Patent 02115758.8 discloses a kind of organic composite rectorite and preparation method thereof, and organic rectorite therein is made up of rectorite, organic intercalation agent (aminoacid such as long chain alkyl ammonium salt, hexamethylene diamine adipate or carbon number 6～12), protonating agent.So-called organic intercalation agent is organic modifiers.Such as, alleged long chain alkyl ammonium salt intercalator is hexadecylamine, cetyl trimethyl amine (sic) or other long chain alkyl ammonium salt that carbon number is 12～18, for single-long-chain alkyl quaternary ammonium salt, the organic intercalation agent that every 100 parts of rectorites add at most can to 30 parts.Even if the rectorite adopting purity more than 90% is raw material, prepared organic rectorite interplanar distance d [001] the highest being only capable of reaches 3.8～4.1nm.
Patent 02115876.2 discloses a kind of rectorite organic compound for synthesizing nano compound material and preparation method thereof, and its organic rectorite complex is made up of rectorite and the organic monomer such as amine or amine salt, aminoacid, lactams, diamine diacid salt or organic monomer and protonating agent generation ion-exchange reactions.According to document " rectorite application in polymer nanocomposites " (" engineering plastics application " 2004,32nd volume, 1st phase) report, apply this technology, brought up to 4.2924nm through the interplanar distance d [001] of the High-purity Rectorite/organic double compound obtained by organic cation exchange reaction by 2.2616nm.
In above-mentioned two patent, organic rectorite is made up of clay/organic modifiers/protonating agent three kinds component or two kinds of components of clay/organic modifiers, organic modifiers therein does not include the quaternary ammonium salt of double long-chain alkyl, modifier molecules amount is not adequate height, and its product that organises not easily obtains bigger interplanar distance.
As the example preparing organic rectorite with ultrahigh molecular weight for organic modifiers, patent 200610124484.6 discloses a kind of nano composite material of quaternary ammonium salt of chitosan/rectorite and preparation method thereof, this composite is a kind of organic rectorite substantially, basic composition is chitosan quaternary ammonium salt and rectorite, with chitosan quaternary ammonium salt for organic modifiers, after intercalation, rectorite interplanar distance d [001] is between 2.9nm～3.5nm.Another is 200910213896.0 about the patent relating to organic rectorite of chitosan quaternary ammonium salt organic modifiers, and organic modifiers used is carboxymethyl chitosan quaternary ammonium salt, and the interplanar distance d [001] of its organic rectorite is between 4.2nm～4.72nm.But, chitosan class quaternary ammonium salt with high costs, its organic rectorite product orientation, in medical material, biomaterial, does not possess the economy in field application such as oil drilling, coating, engineering plastics, rubber.
Patent 201010258856.0, patent 201510893277.6, patent 201511005536.3 disclose several different oil base drilling fluid organic rectorite and production method thereof, organic rectorite therein is all be made up of rectorite and single-long-chain alkyl quaternary ammonium salt, and it is m-alkylpolyoxyethylene or n-alkyl-dimethyl benzyl ammonium halide that its claim, summary of the invention illustrate the general term of quaternary ammonium salt-modified dose used.Therefore, with regard to organic modifiers molecular weight contrastingly, its product that organises not easily obtains bigger interplanar distance.
If adopting this brand-new component of rectorite/double long-chain alkyl quaternary ammonium salt, just can improve the interplanar distance of its organic clay finished product, two approach of previously described raising organic clay interplanar distance are all achieved, the place of this products innovation of present invention just.Rectorite is a kind of novel interbed silicate mineral, and in its crystal structure, class montmorillonite layer and class mica layer are staggered with 1:1 rule.The d [001] of natural accumulation supporting stone is 2.2～2.7nm, is about the twice of montmorillonite.Rectorite layer charge is moderate, has both had good ion exchangeable, can have good dispersion fissility.Adopting appropriate technique, rectorite is suitable for carrying out organic modification with the organic modifiers of the macromolecules such as double long-chain alkyl quaternary ammonium salt.
Two, the big interplanar distance organic clay meaning to low toxic and environment-friendly non-aqueous drilling fluids
In oil drilling process, non-water based drilling fluid (NADFs) i.e. oil base and synthetic base drilling fluid are more and more extensive in the application of petroleum industry, based on diesel oil based before the base fluid of oil base drilling fluid system.But, diesel oil aromatic hydrocarbon content is higher, is unfavorable for environmental protection.In recent years, impact environment caused for reducing drilling cuttings to discharge, the application with degradable, the low toxicity mineral oil (white oil) of oligosaprobic environment-friendly type, high refined mineral oil and synthesis base (ester, alkane, alkene) drilling fluid is more and more extensive.Oil base drilling fluid beyond diesel oil and synthetic base drilling fluid, can be referred to as low toxic and environment-friendly type drilling fluid.But, the system of these low toxic and environment-friendly type drilling fluids is characterized as being that viscosity is low, aromatic content is low, organic clay for oil base drilling fluid in the market as the gelation of the oleophylic colloid of low toxic and environment-friendly system, filtration reduction, that thickening puies forward cutting property is generally poor.
