Abstract
The present invention is one kind of biodegradable lubricant oil with excellent low temperature flowability and its production process. Refined vegetable oil after low temperature freezing and filtering is mixed with cleaning dispersant, antioxidant, antirust agent, extreme pressure antiwear agent, foam resisting agent, anticoagulant, etc to form the lubricant oil. The lubricant oil has excellent low temperature flowability and biodegradable performance, and may be used in field operation of forest, tour water area and other places with strict environment friendship requirement in cold area.
Description
Technical field:
The present invention relates to a kind of the have Biodegradable lubricant oil of excellent low temperature flowability and the processing method of producing lubricating oil thereof, its characteristics are to be not raw material with the petroleum-type product, but are that raw material is made lubricating oil and solved the bad shortcoming of common vegetable oil low-temperature flowing property with the refined vegetable oil.
Background technology:
Traditional lubricant base all is raw material manufacturing with the petroleum products, advantages such as chemical stability is good though petroleum products has, wide material sources, low price, but thereby underground, water body causes environmental pollution because petroleum base lubricating oil in use can be scattered by all means, petroleum products belongs to Nonrenewable resources in addition, causes in recent years people to substitute petroleum resources striving to find reproducible resource.Have viscosity index height, flash-point height, biodegradable, advantage such as resource is renewable when vegetables oil is used as lube stock, but owing to exist a large amount of polyunsaturated fatty acids and saturated fatty acid to make that oxidative stability difference and low-temperature fluidity were poor when vegetables oil used as lubricant base in the vegetables oil.
Summary of the invention:
Saturated fatty acid content improves its low temperature flowability so that the lubricating oil that vegetables oil makes has the novel process of better low-temperature fluidity in a kind of method reduction vegetables oil thereby technical problem to be solved by this invention provides.
The technical solution adopted in the present invention is that refined vegetable oil is through crystallisation by cooling → filtration → interpolation detergent-dispersant additive, oxidation and corrosion inhibitor, rust-preventive agent, extreme pressure anti-wear additives, foam reducing composition, antithrombotics etc. → mediation → finished lube.
The new process of production of vegetables oil lubricating oil of the present invention is to have increased crystallisation by cooling on the basis of the existing salad oil technological process of production, filtered and degreased and lubricating oil mediation operation, by freezing it is crystallized out from grease the saturated fatty acid that influences the vegetable oil low-temperature flowing property, make the triglyceride that crystallizes out be easy to filter and the base oil that obtains different pour points by adjusting greasy cooling rate with outlet temperature, by filtration it is separated with grease, be difficult for a filtering difficult problem by the pre-coated filter aid agent with the saturated fatty acid triglyceride that solution crystallizes out in filtration, the base oil that obtains adds detergent-dispersant additive, oxidation and corrosion inhibitor, rust-preventive agent, extreme pressure anti-wear additives, mediations such as foam reducing composition obtain finished lube.
But crystallization apparatus of the present invention relies on the cool brine of refrigerator generation or cold ethylene glycol solution that the cold that makes the grease cooling is provided for crystallizer with the whipping appts of spiral coil cooling tube or cooling jacket and stepless speed regulation.
Greasy cooling is divided into three phases, and the fs is fast cooling, stirs fast that cooling rate is 10 ~ 15 ℃/hour, and stirring velocity is 15 ~ 30 rev/mins, and greasy temperature is reduced to 30 ℃; Subordinate phase at a slow speed the cooling, stirring at low speed, cooling rate is 1 ~ 4 ℃/hour, stirring velocity is 3 ~ 10 rev/mins, and greasy temperature is reduced to 3 ~ 8 ℃; Phase III keeps temperature 8 ~ 12 hours so that nuclei growth is convenient to filter for there not being the insulation of stirring growing the grain process.
Filter plant adopts the vertical blade filter, adopts the method for adding flocculating aids for accelerating filtration velocity, and the flocculating aids of use is included as diatomite, perlite or its mixture.
Vegetable oil lipoprotein of the present invention comprises soybean oil, rape seed oil, Semen Maydis oil, Oleum Helianthi; Employed detergent-dispersant additive comprises sulfide isobutene barium salt, high base number synthesising sulfonate; Mono alkenyl butyryl imines; Oxidation and corrosion inhibitor comprises: sulphur phosphorus fourth octyl group zinc salt, sulphur phosphorus alkylphenol zinc salt.Rust-preventive agent comprises: clorafin fat barium soap, petroleum sodium sulfonate, barium mahogany sulfonate; Extreme pressure anti-wear additives has boric acid ester, clorafin; Foam reducing composition comprises the multipolymer of dimethyl silicone oil, acrylate and propylene oxide; Pour point depressant comprises polyalphaolefin and polymethacrylate.
Lubricated oil composition comprises refined vegetable oil, detergent-dispersant additive, oxidation and corrosion inhibitor, rust-preventive agent, extreme pressure anti-wear additives, foam reducing composition, antithrombotics after treatment, and each set of dispense ratio is:
Refined vegetable oil: 60 ~ 90 parts of detergent-dispersant additives: 0.1 ~ 3 part
Oxidation and corrosion inhibitor: 1 ~ 5 part of rust-preventive agent: 0.5 ~ 2 part
Extreme pressure anti-wear additives: 0.2 ~ 3 part of foam reducing composition: 0.1 ~ 0.5 part
Antithrombotics: 0.1 ~ 2 part
Description of drawings:
Fig. 1 is the Biodegradable lubricant oil process flow diagram.
Fig. 2 is Biodegradable lubricant oil production principle figure.
Embodiment:
The present invention is described further below in conjunction with example:
The equipment that this example adopted mainly contains crystallizer, refrigerator (not expression in the accompanying drawing), filter, Mixer pot and various pump (not expression in the accompanying drawing), basin (not expression in the accompanying drawing) etc., and accompanying drawing 1 is seen in its technical process.
Example: 1. 50 ℃ of soybean oil place crystallizer that the band adjustable speed stirs, under 20 rev/mins of stirring velocitys, cool brine by the crystallizer chuck, with per hour 10 ℃ speed cooling 2 hours to 30 ℃, regulate crystallizer stirring velocity to 5 rev/min, by regulating the cool brine flow,, kept temperature 10 hours with per hour 2 ℃ cooling rate cooling 12 hours to 6 ℃; The vertical blade strainer 2. in the super-cell of precoating weight of oil 3%, the oil with advantages of good crystallization filters then; After reaching prescribed value to filter resistance, stop oil-feed, slough solid fat filter cake with the pressurized air blowback, enter next filtration cycle, two strainers are used alternatingly, and the soybean oil after the filtration is standby.
3. the soybean oil of getting after the filtration places Mixer pot for 90 parts, add 2 parts of mono alkenyl butyryl imines successively, 4 parts of sulphur phosphorus alkylphenol zinc salts, 1 part of barium mahogany sulfonate, 0.5 part of boric acid ester, methyl-silicone oil 0.3,0.5 part of part of polyalphaolefin fully mixes after 20 minutes and obtains finished lube, the pour point of this lubricating oil is less than-25 ℃, and has biodegradable, can be used for environmentally friendly property such as cold district forest, tourism waters have requirement outdoor work equipment.
