Description
One, technical field: the present invention relates to a kind of grease manufacture technology, especially high temperature grease and preparation method.
Two, background technology: at present, mechanical used lubricating grease is varied, has satisfied the production needs to a certain extent, but along with development of science and technology, original lubricating grease can not satisfy the needs of special mechanical.
Three, summary of the invention: the purpose of this invention is to provide a kind of megathermal high temperature grease and preparation method, satisfied the needs of producing to a certain extent, the object of the present invention is achieved like this, and it is made by following raw material:
Lithium series base oil A3 (lithium material oil) 2200kg*6=13200
Phenylformic acid 59kg*8.3=484
Pentanoic 3.5Kg*16.92=58
Stearic acid 143kg*6.1=872
Aluminum isopropylate 216Kg*14.7=3200
T706 1Kg*32＝32
68# synthesizes cylinder stock oil 480Kg*7.2=3456
Micro powder graphite 720Kg*4.8=3456
Dibutyl phthalate 6KG*13=78.
The preparation method: the first step feeds intake, close pipe valve at the bottom of the refining still still, dropping into 600Kg, to press the molten material oil of still lithium series base oil A3 be lithium material oil, opens bottom wing, interior outer wing stirs 45-50Hz,, temperature rises to 60 ℃, drops into phenylformic acid 59kg, temperature rises to 75-80 ℃, stop the supple of gas or steam, constant temperature stirred 30 minutes, dissolved to phenylformic acid.Add stearic acid 143kg intensification oil (lithium series base oil A3 is a lithium material oil) 300Kg, aluminum isopropylate 108Kg stirs 15 minutes secondaries and adds aluminum isopropylate 108Kg.
The second step replacement(metathesis)reaction, temperature rises to 125-130 ℃, adds the 40-45Kg pure water, replaces, and stirs 20-30 minute.Continue to heat up (will slowly heat up, prevent the jar that overflows).
Three-step reaction is warming up to 180-185 ℃, constant temperature 180 minutes.After constant temperature finishes, begin cooling.
The cooling of the 4th step after constant temperature finishes, begins cooling, pours material into the finished product still rapidly through 40 order filtering nets.The finished product still feeds recirculated water, adds the oily 400Kg of cooling.Temperature is reduced to 120-125 ℃, adds pentanoic 3.5Kg dibutyl phthalate 6KG, T7061Kg, 150Kg (the lithium series base oil A3) pipeline purging of the end of falling still back.Free soda acid (being controlled at neutral little acid-0.38% oleic acid) (according to base oil acidity, suitably adjusting free soda acid standard) is surveyed in sampling.
The 5th step is thick to add the agent aftertreatment, before the still, synthesize cylinder stock oil 480Kg and lithium series base oil A3220Kg at the cooling still with 68#, micro powder graphite 720Kg is warming up to 85 ℃ of fusings, again work in-process is poured into cooling still, filter 23 0 minute, add the oily 200Kg of cooling, and sampling survey cone penetration, according to the cone penetration situation, the usefulness of coagulating the soup (lithium series base oil A3).After homogeneous finished, sheared 60 minutes with the 0.8mm plate by one pump with 80 order net filtrations, the while for a pump, and in the re-shearing process, cone penetration is surveyed in sampling, according to the cone penetration situation, and the usefulness of coagulating the soup in proportion (lithium series base oil A3).0.8mm plate after cone penetration is suitable, outgased 60 minutes after shearing and finishing, and observed (the roughness of oil product again in the degasification process; Impurity; Color; Bubble) degassing is after 60 minutes, and dropping point is surveyed in sampling.Cone penetration 400-430.
The 6th step finished product is canned, and outward appearance is qualified, after cone penetration is suitable, adds 80 order filtering nets at canned mouthful, and hay tank is dressed up product.
Range of application of the present invention: the bale panoramic tables of metallurgy industry roll for hot-rolling bearing, continuous casting installation for casting, crystallizer, two cold-zones, fan-shaped segment roller bed, straightening machine and pendulum shearing machine, conveying roller are lubricated etc.
Meaning of the present invention is: 1, excellent high-temperature behavior, and high temperature can keep certain denseness down, and high temperature service life is long; 2, the empty resistance to abrasion of good extreme pressure, the spherical viscosifying agent particle of ball can form the spin layer at contact surface, effectively reduces the metallic surface friction; The life cycle of prolongation equipment; 3, anti-rust and anti-corrosion is good, and the anti-seawater of energy is to the erosion of metal friction surface.
Four, embodiment: the present invention is made by following raw material:
Lithium series base oil A3 (lithium material oil) 2200kg*6=13200
Phenylformic acid 59kg*8.3=484
