Description

Antiwear additive and preparation method thereof
Technical field
The present invention relates to a kind of antiwear additive, and in particular to a kind of antiwear additive and its preparation for being used to improve diesel oil abrasion resistance Method.
Background technology
At present for the requirement to environmental protection and reduction exhaust gas discharge, it is necessary to more environmental clean diesel oil, diesel oil mark Standard is being continuously improved, and the diesel oil of deep processing is due to being stripped of the elements such as nitrogen among diesel oil, sulphur, the removing of these elements Also reduce the abrasion resistance of diesel oil at the same time so that diesel engine is more prone to be worn, therefore diesel antiwear additive makes Dosage and the market demand are in continuous enlargement.
Existing diesel antiwear additive is mostly fatty acid type and fatty acid ester type, and this type antiwear additive is C18 acid, and difference is added The sensitivity of hydrogen diesel oil is different, and using effect is unstable.
The content of the invention
It has been investigated that antiwear additive is three-dimensional or cyclic structure and longer strand, then more preferable sense can be obtained By property and abrasion resistance.In view of this, in order to solve the shortcomings of the prior art, the present invention provides a kind of antiwear additive and its Preparation method.It is mainly used for the raising of diesel oil abrasion resistance, makes an addition among diesel oil.
The technical solution adopted in the present invention is：A kind of antiwear additive, includes the raw material of following parts by weight：Lignin acid 18.5-21.5 parts；19.5-20.5 parts of stearic acid；18.5-21.5 parts of 38.5-41.5 parts of glass cement oil and pentaerythrite.
Further, the raw material of following parts by weight is included：20 parts of lignin acid；20 parts of stearic acid；Glass cement oil 40 parts and 20 parts of pentaerythrite.
Further, the glass cement oil is formed by the glass cement of 65wt% and the technical white oil compounding of 35wt%.
A kind of preparation method of the antiwear additive, comprises the following steps：
(1) lignin acid, stearic acid, glass cement oil and pentaerythrite are uniformly mixed according to a ratio, obtain mixed liquor；
(2) mixed liquor is carried out being heated to reaction completion, when the time of the reaction is 5-6 small, is then taken off Water, finally carries out being cooled to less than 90 DEG C, obtains intermediate product；
(3) heavy aromatics of the 10-20% of the intermediate product weight is added into the intermediate product, is kept stirring, and It is cooled to room temperature, obtains finished product antiwear additive.
Further, it is mixed into described in step (1) and first by lignin acid, stearic acid and glass cement oil mix for the first time Close, carrying out second with pentaerythrite again after mixing mixes, and obtains mixed liquor after mixing.
Further, the temperature heated described in step (2) is 120-130 DEG C.
Further, it is cooled to the intermediate product being cooled to temperature as 80-90 DEG C described in step (2).
Further, the moisture of the dewatered intermediate product is less than 0.03% in step (2).
Further, the additive amount of heavy aromatics described in step (3) is the 15% of the intermediate product weight.
In the following, raw materials used do in the present invention is discussed in detail：
Lignin acid：That is lignin sulfonic acid, also known as lignosulfonate, Tan solid, there is good diffusivity.Dissolve in The aqueous solution of various pH value, insoluble in organic solvent.Lignin acid and its esters are industrially widely used as dispersant and wetting Agent, such as oil drilling slurry dispersant, rubber wear-resisting agent.
Stearic acid：Stearic acid, i.e. octadecanoid acid, are produced by grease hydrolysis, mainly for the production of stearate.
Glass cement oil：Glass cement oil is formed by 65% glass cement and 35% technical white oil compounding.Glass cement is a kind of Binder, main component form for sodium metasilicate and the silicone of acetic acid and Organic.Technical white oil refers to the white oil of technical grade, is high Degree refining product, it is colourless, tasteless, it is nontoxic, it is mainly used for chemical fibre, closes fine, textile machine rubber plasticizing, precision instrument, synthesis tree Fat.
Pentaerythrite：White crystals or powder, it is flammable, easily by general esterifying organic acid, it is largely used to coatings industry production The raw material such as alkyd resin, synthesis quality lubricant, plasticizer, surfactant and medicine, explosive.
Heavy aromatics：Refer to the BTX aromatics that molecular weight is more than dimethylbenzene, be mainly derived from and reform heavy aromatics, drippolene weight virtue Hydrocarbon and coal tar, are a kind of BTX aromatics using C9 aromatic as main component, and solvent use is done in the present invention.
Diesel antiwear additive is also known as diesel fuel lubricity, refers to the characteristic that diesel oil can prevent diesel injection system (FIE) from wearing. The properties of product of diesel antiwear additive reduce the injection pump degree of wear to improve diesel fuel lubricity；Reduce the mill of fuel injection system Damage, improves engine life；Tank for gaseous or liquid substances and pipeline are protected from corrosion；Do not influence nozzle cleaning.The present invention with lignin acid and Stearic acid is synthon, is reacted with pentaerythrite, and then dehydration is refined, and is synthesized a kind of new as solvent using heavy aromatics Type diesel antiwear additive.Acid and pentaerythrite reaction using two kinds of different molecular weights, obtain with ring-type and multilayer stereo knot The antiwear additive monomer of structure, make its metal surface adhere to one layer of multidirectional wear-resistant protective layer, than single structure protective film effect more It is good, the adaptability of antiwear additive is also strengthened, to improve abrasion resistance and sensitivity (the sensitivity i.e. difference to different hydrogenated diesel oils For the diesel oil of property when adding same antiwear additive, abrasion resistance improves difference, and wear resistence improvement is more obvious, says The bright diesel oil is preferable to such a antiwear additive sensitivity).
Beneficial effects of the present invention are：Antiwear additive produced by the present invention is adaptable, available for various Atmospheric vacuums, urges The wear-resisting property of change and hydrogenated diesel oil is improved, and is all had well to the diesel oil of different material and technique after tested Abrasion resistance；Superior performance, more efficiently, addition is between 70-300PPM, and wear scar diameter is averagely less than 410 millimeters, performance Fully meet and be better than industry relevant criterion, addition can reduce 10-16% compared with existing antiwear additive；Meet diesel oil constantly to rise The environmental requirement of level.
