Abstract
The preparation of extreme pressure antiwear agent for lubricant oil includes the reaction between organic modified clay and C4-C24 carboxylic acid compound in the presence of solvent and at 100-160 deg.c and product separation and collection. Hydroxyl radical in the edge of clay layer and acid anhydride or carboxylic acid produce esterification reaction, so that the clay layer is grafted with long carbon chain. The prepared extreme pressure antiwear agent has better dispersivity and extreme pressure antiwear performance, contains no S, P, Cl and other elements. The prepared extreme pressure antiwear agent has wide application foreground and may be used in various industrial lubricant oil for cutting, rolling, punching, etc.
Description
Technical field
The invention belongs to lubricating oil additive, specifically, is a kind of preparation method of extreme pressure anti-wear additives.
Technical background
Be the material of sulfur-bearing, phosphorus, chlorine at present at lubricating oil field practical and effective extreme pressure anti-wear additives, though good effect is arranged, but also can exert an adverse impact to environment, so development no sulphur, phosphorus, chlorine or low-sulfur, phosphorus, free from chloride product are the direction that develops of extreme-pressure anti-friction additive from now on.
Clay is widespread in nature, and is still organically-modified no matter be inorganic as a kind of inorganic materials, all is used widely.Because the laminated structure of clay uniqueness, interlayer has the ion such as the Na that can be exchanged
+, K
+, Mg
2+Deng, can be given clay with the organic character of parent by the ion of other large volume such as ammonium, phosphine, oxygen, the exchange of sulfonium plasma.The neutral polar molecule also can embed between clay seam, thereby clay is organised.
Organo-clay is used very wide, as: CN1052094A carries out the interlayer ion exchange with the mixture reaction of wilkinite and quaternary amine or quaternary amine and tertiary amine, and products therefrom can be used as the anti-sedimentation agent of grease thickener, paint etc.CN1238353A discloses the preparation method of clay-rubber nm-class composite material.CN1255510A has introduced the preparation method of the matrix material of polyolefine and clay.US4810734 has introduced and a kind of clay and polymkeric substance has been combined with ionic linkage, thereby makes clay be dispersed in method in the polymeric matrix.Above-mentioned patent is all utilized the laminated structure of clay, and clay is dispersed in the polymeric matrix, and mechanical property is greatly improved.Especially in CN1212716, describe the exchangable ion that utilizes between clay seam in detail, after particularly ammonium cation exchanges as ion, further generate polymer-organoclay composite in several modes with polymkeric substance.On the other hand, utilize the reaction of hydroxyl on the lamella edge and coupling agent, as the supporting process that generates matrix material, in relevant patent, also have related, as above-mentioned CN1238353A.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of novel extreme pressure anti-wear additives, this method directly utilizes the hydroxyl on the clay layer to react, and is synthetic easy.
The preparation method of extreme pressure anti-wear additives provided by the invention comprises: with organo-clay and C
4-C
24Carboxylic acid compound reacts under 100-160 ℃ in the presence of solvent, the Separation and Recovery product.
Specifically with organo-clay and C
4-C
24, preferred C
12-C
22Carboxylic acid compound in 100-160 ℃, under preferred 100-130 ℃, react 4-40 hour in the presence of solvent, and preferred 6-30 hour, steam solvent, usefulness base oil stripping product gets final product.
Said clay is selected from wilkinite, polynite, attapulgite etc.Organically-modified is to use ion, as the ion that can be exchanged between ammonium, phosphine, oxygen, sulfonium etc. and clay seam, as Na
+, K
+, Mg
2+Deng carrying out ion-exchange, give clay with the organic property of parent.Said organo-clay can be the commercial goods, also can be according to conventional method of modifying self-control.Comparatively general method of modifying is that clay and alkylamine or aminocarboxylic acid, hydrochloric acid are added in the distilled water, is warmed up to 30-90 ℃, and the best be 60-80 ℃, fully stirs, and with muddy liquid centrifugation, uses the distilled water repetitive scrubbing to arrive no Cl
-Detect,, obtain product isolate vacuum-drying at room temperature.
Said carboxylic acid compound is selected from C
4-C
24Carboxylic acid, acid anhydrides and carboxylic acid and the adduction product of acid anhydrides, preferably carbon number is C
12-C
22, preferred oleic acid, sebacic acid, Succinic Acid, hexosamine, lauric acid (C
12), tetradecanoic acid (C
14), palmitinic acid (C
16) and erucic acid (C
22).
Organic solvents such as selected solvent can toluene, dimethylbenzene, benzene, ethanol, ethylene glycol, methyl-phenoxide, preferably reflux temperature is at 100-160 ℃ organic solvent.
The present invention synthesizes the raw material of extreme pressure anti-wear additives with the organo-clay conduct.Because clay is a silicate minerals, silicon itself has very high fusing point, and the clay particle degree is little, the secondary interface of engaging friction preferably.In organic solvent, by solvent " swelling ", the clay of multilayered structure is scattered in the solvent with monolithic layer through organically-modified clay.Utilize hydroxyl and the acid anhydrides or the carboxylic acid generation esterification at lamella edge, make clay layer connect long carbochain, can improve oil soluble, and resistance to abrasion and extreme pressure property also are improved.
The extreme pressure anti-wear additives of the inventive method preparation has dispersiveness and extreme pressure anti-wear preferably, elements such as sulfur-bearing, phosphorus, chlorine not, and simple synthetic method has very wide development and application prospect, can be applicable to machining oil, ROLLING OIL, punching press wet goods industrial lubricant.
