Description

A kind of air compressor oil and preparation method thereof
Technical field
The present invention relates to chemical field, more particularly to air compressor oil, particularly a kind of air compressor oil and its system Preparation Method.
Background technology
Air compressor oil, refer to for the air compressor lubrication of movement cylinder part and air bleeding valve in operation, with Effectively protection screw rod, bearing, the part such as gear, and played by oil circulation and parts are cooled down, antirust and peace and quiet effect, simultaneously For a kind of oil product to seal to screw rod and housing.Because air compressor is constantly in high pressure, high temperature and has cold In environment existing for condensate, therefore air compressor oil should have excellent high temperature oxidation resistance, low tendency to soot, excellent Viscosity temperature characteristic, good oil-water separativeness and rustless property.Air compressor oil is broadly divided into mineral type and synthesis type at present Two major classes, the former, can be bad there is high-temperature oxidation stability as conventional air compressor oil, and product service life is not grown (general 2000h or so), there is high tendency to soot, changed oil when so causing using machine frequently, energy consumption is big, is unfavorable for saving Energy, environmental protection, the novel economizer development idea of sustainable development.It is (general that the latter can effectively improve oil product service life problem 6000h or so), can also solve the carbon-collecting problem of compressor in operation, still, due to making using synthetic ester and polyalphaolefin The cost for causing product in use for raw material is too high, considerably increases the cost using air compressor oil so that product exists Cost performance in use is not high, and the ratio that market uses is not high all the time.
Poly-alpha olefins (PAO) be by ethene it is aggregated reaction alhpa olefin is made, it is further aggregated and hydrogenation and be made. It is the most frequently used synthetic lubricant base oil, and use range is most extensive.Poly alpha olefine synthetic oil (abbreviation PAO) has good Viscosity temperature characteristic and low temperature flow, it is to prepare base oil high-grade, that special lube is ideal.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of air compressor oil, described this air compressor oil Solving air compressor oil high-temperature oxidation stability of the prior art can be bad, and product service life is not long, high carbon deposit Question of The Tendency and the high technical problem of operating cost.
The invention provides a kind of air compressor oil, including it is modified vegetable oil, base oil, antioxidant, antirust agent, wear-resistant Agent, detersive and dispersant, described base oil are PAO, mass percent of the described base oil in air compressor oil For 30%~40%, mass percent of the described antioxidant in air compressor oil is 1%~5%, described antirust agent Mass percent in air compressor oil is 1%~5%, mass percent of the described antiwear additive in air compressor oil For 1%~5%, described detersive is 1%~2% in the mass percent of air compressor oil, and described dispersant is in sky The mass percent of air compressor oil is 1%~2%, and surplus is described modified vegetable oil；Defoamer is also added with, it is described The concentration of defoamer is modified vegetable oil, base oil, antioxidant, antirust agent, antiwear additive, detersive and dispersant quality sum 50-100ppm；
Further, the formula of described modified vegetable oil is as follows：
Wherein R1、R2、R3Respectively carbon number is any one in 12-23 alkyl or alkylene.
Further, described antioxidant is 2,6-di-tert-butylphenol or 2,6-BHT or phenolic ester type Any one in antioxidant.
Further, described antirust agent is any one in barium mahogany sulfonate, petroleum sodium sulfonate or zinc naphthenate.
Further, described antiwear additive is (appointing in chlorinated paraffin, trimethyl phosphate phenol or trithiophenyl phosphate Meaning is a kind of.
Further, described detersive is polyisobutene sulphur barium phosphate salt, alkyl sodium salicylate or sulfenyl phenolate Any one in calcium.
Further, described dispersant is any in mono butonediimide ashless dispersant agent or trimethyl phosphate phenol It is a kind of.
Further, described defoamer is non-silicon composite anti-foam agent.
Present invention also offers the method for preparing above-mentioned air compressor oil, comprise the following steps：
The step of step 1) prepares modified vegetable oil including one, two or more any vegetable seed is selected first Oil, peanut oil, cotton seed oil, olive oil are raw material, first carry out hydrofinishing, in unifining process, the reaction pressure of reactor For 6~12MPa, reaction temperature is 200~400 DEG C, and the total air speed of oil-feed be 0.5~1.0/h, reaction hydrogen to oil volume ratio for 600~ 800, the catalyst in described unifining process is Ni-W/AL2O3Or Ni-Mo-Co/AL2O3, then carry out Atmospheric vacuum steaming Evaporate, reduced pressure distillation process is 1~65mmHg of residual voltage, cuts 300~460 DEG C of atmospheric distillate, obtains hydrogenated vegetable oil；Then An alkali cleaning, the NaOH solution for being 6%-10% with concentration are carried out, dosage is to be modified the 2%-6% of basic weight of oil, temperature control System after washing 60-90min, after oil water separator, is once washed at 70-80 DEG C into next reactor, is used Measure and 60-90min is washed, after oil water separator at 70-80 DEG C for the 5%-10% of the basic weight of oil of modification, temperature control； Secondary alkali cleaning is carried out, uses the aqueous solution to be washed for the salt of alkalescence, the Na for being 5%-8% with concentration2CO3Solution, dosage are to change Property basis weight of oil 1%-5%, temperature control is at 70-80 DEG C, after washing 60-90min, after oil water separator, enters Once washed in next reactor, dosage for modified basic weight of oil 5%-10%, temperature control at 70-80 DEG C, After washing 60-90min, after oil water separator, modified vegetable oil is obtained；
Step 2) according to mass percent weigh PAO, modified vegetable oil, antioxidant, antirust agent, antiwear additive, detersive, point Powder and defoamer, PAO and modified vegetable oil are then first added in a reactor, 80 DEG C -100 DEG C are stirred 20~50 points Zhong Hou, antioxidant, antirust agent, antiwear additive, detersive, dispersant and defoamer are added, mix and obtain air compressor oil.
The preparation method of the air compressor oil of the present invention is to add vegetable oil in a kettle, after hydrofinishing, Pass through alkali cleaning twice again and wash twice, obtain modified vegetable oil；Hydrocarbon (PAO) will be synthesized and modified vegetable oil squeezes into reactor In, after stirring, add antioxidant, antirust agent, antiwear additive, detersive, dispersant and defoamer.Air compressor of the present invention Oil has good high temperature oxidation resistance, low tendency to soot, excellent viscosity temperature characteristic, good oil-water separativeness and antirust Performance, modified vegetable oil is added in addition, greatly reduce the cost using air compressor oil, meet energy-saving and environmental protection, can hold The novel economizer development idea of supervention exhibition.This product drain period performance is considerably longer than conventional air compressor oil.
The present invention compares with prior art, and its effect is positive and obvious.A kind of air compressor oil tool of the present invention Have the advantage that:
1. this product open flash point can arrive 270-300 DEG C, below -40 DEG C of pour point, the opening of conventional air compressor oil is dodged For point at 220-240 DEG C, the security performance of this product is high.
2. the oxidation stability (rotary bomb oxidation test) of this product can reach more than 2500h, traditional product oxidation stability exists Between 1000h-1200h.
3. the oil product of this product can reach more than 8000h in 85 DEG C -95 DEG C of usage time, traditional oil product is in 2000h- Between 4000h, oily periodic performance is considerably longer than conventional air compressor oil, has saved production cost.
4. this product adds reproducible modified vegetable oil, cost is saved, safety and environmental protection, has met sustainable development Strategy.
