Abstract
The invention discloses lubricating oil detergent and a preparation method thereof. The detergent is prepared from the following raw materials in parts by weight: 1 part of linoleic acid, 1-2 parts of neutral oil, 1-6 parts of calcium hydroxide, 0.2-1 part of calcium oxide, 0-0.1 part of calcium chloride, 3-10 parts of solvent, 0.2-1 part of methanol, 0.1-0.5 part of water and 0.1-0.4 part of carbon dioxide. The preparation method of the lubricating oil detergent comprises the following steps of: a high-alkalinity reaction, a neutralization reaction and the like. The lubricating oil detergent disclosed by the invention has better detergency and dispersibility and strong corrosive acid neutralization capacity, and is uniform in calcium carbonate grain size distribution. In the whole reaction process, the preparation and treatment process is simple, free of a high-temperature treatment process and easy to realize on the device. Moreover, most of the materials are regenerative, higher in biodegradability and capable of satisfying the green and environmentally-friendly requirements.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of detergent for lubricating oil and preparation method thereof.
Background technology
In the use of oil engine, the carbon granule, the flue dust that have some fuel combustions and generate advance the people in lubricating oil, more airborne dust also can enter in the oil, and the high temperature oxidation of lubricating oil self can produce acidic substance simultaneously, and these materials combine and will form carbon deposit, greasy filth, cause oil quality to degenerate, wearing and tearing increase, and corrosion increases the weight of, and stop up oil circuit and filter screen, make the piston ring adhesion, mechanical cisco unity malfunction.In order to prevent that these materials from forming, guarantee that oil engine is normal, lasting, economical operation, in lubricating oil, add detergent-dispersant additive, be used for and oil oxidation after the acidic cpd that produces, prevent the further oxidation of acidic cpd, and energy adsorption and oxidation composition granule, make it to be dispersed in the oil, can not fouling and be deposited on the metallic surface, solve the problem of engine idle, stall and running imbalance.At present, mainly contain traditional detergent for lubricating oil products such as sulfonate, naphthenate, alkylbenzene sulfonate on the market, and their the raw material overwhelming majority is from petroleum products.The raw material of the detergent for lubricating oil that these are traditional is non-renewable, and it is after use, and the refuse that is discharged in the environment is biological nondegradable, and therefore, conventional lubrication oil purification agent is not eco-friendly purification agent.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of detergent for lubricating oil and preparation method thereof.Detergent for lubricating oil base number height of the present invention, nanoscale is good, biodegradation intensity is high, environmental friendliness; The preparation method is simple, is easy to scale operation.
For solving the problems of the technologies described above, technical scheme provided by the invention is:
A kind of purification agent, its raw material is formed and the quality proportioning is:

Described linolic acid is the linolic acid that contains acid 〉=50%;
Described neutral oil is the light lubricating oil base oil;
Described solvent is a kind of in normal heptane, octane, toluene or the dimethylbenzene.
A kind of preparation method of detergent for lubricating oil, step comprises:
A, the linolic acid with formula ratio, neutral oil, solvent, methyl alcohol and calcium chloride add in the reactor, mix and stir, and add calcium hydroxide and the calcium oxide of formula ratio then, in 35 ℃-80 ℃ and 1.0-3.0 hour;
The water of B, adding formula ratio is warming up to 45 ℃-85 ℃, feeds the carbon dioxide of formula ratio, reacts 0.5-2.0 hour, and Ventilation Rate is 20-120mL/min;
C, centrifugal or adding flocculating aids filter and remove residue, underpressure distillation is sloughed solvent and is namely made the final product detergent for lubricating oil again.
Linoleic acid dimer calcium salt detergent for lubricating oil of the present invention, its total basicnumber is 200-360mgKOH/g, have detergent-dispersant performance preferably and extremely strong in and the ability of corrosive acid, compare with purification agent product in the market, calcium carbonate even particle size distribution in the Linoleic acid dimer calcium salt detergent for lubricating oil, it is 40-180mm 100 ℃ of kinematic viscosity
2/ s; In entire reaction course, preparation and treatment process are simple, need not adopt high-temperature processing technology, on device, very easily realize, the most of reproducible resource of the raw material of Linoleic acid dimer calcium salt detergent for lubricating oil of the present invention, having higher biodegradability, is eco-friendly product, meets requirements of green environmental protection.
