The preparation method: the first step feeds intake, off-response still and circulation line pipe valve, drop into 400Kg and press still oil (HVI Ia650 base oil), open bottom wing, interior outer wing stirs 45-50Hz, heating agent is controlled at 260-280 ℃, and temperature rises to 65-75 ℃, drops into (diphenylmethanediisocyanate (MDI)) isothermal reaction 30 minutes; To dissolve and jar dissolve completely that n-octyl amine, Yantai aniline, HVI Ia650 base oil 100Kg are warming up to 65-75 ℃ of input reactor.
The second step reaction, add neat above-mentioned raw materials after, be warming up to 110-115 ℃, isothermal reaction for the first time 60 minutes; After constant temperature finishes, continue to heat up, heating agent is controlled at 260-280 ℃, at 189-191 ℃ of constant temperature 60 minutes for the second time.
The 3rd step is thick, and constant temperature is poured material into blending kettle rapidly through 40 order filtering nets after finishing, 200Kg (the HVI Ia650 base oil) pipeline purging of the end of falling still back; Blending kettle is before batch turning, and adding 100Kg washes still oil and is warming up to 60-70 ℃, drops into stearyl alcohol.
The 4th step is thick to add the agent aftertreatment, after the blending kettle material is neat, drops into whole 150BS base oils, Viscotrol C filtered homogeneous 60 minutes, opened circulating water cooling, and sampling survey cone penetration, according to the cone penetration situation, and the usefulness of coagulating the soup (HVI Ia650 base oil).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 (HVI Ia650 base oil).0.8mm after plate is sheared and finished, use the 0.5mm plate instead and sheared 60 minutes, in the re-shearing process, when temperature is reduced to 70-80 ℃, add respectively in order:
Oxidation and corrosion inhibitor T202 73.9kg (pressing base oil 2% increase and decrease);
Tritolyl phosphate (TCP) 24.3kg (pressing base oil 0.5% increase and decrease);
Rust-preventive agent T706 1.4kg.
After adding the agent end, circulation was stirred 60 minutes, and cone penetration is surveyed in sampling, according to the cone penetration situation, and the usefulness of coagulating the soup in proportion (HVI Ia650 base oil), after cone penetration was suitable, double pump outgased 60 minutes, observed (the roughness of oil product again in the degasification process; Impurity; Color; Bubble) degassing is after 60 minutes, and dropping point 286-308 is surveyed in sampling.No. 2 265-295 of cone penetration, No. 1 310-340, No. 0 355-385.
The 5th 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: fan-shaped segment roller bed, straightening machine and pendulum shearing machine, conveying roller are lubricated etc.
Meaning of the present invention is: 1, the empty resistance to abrasion of good extreme pressure, and 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; 2, anti-rust and anti-corrosion is good, and the anti-seawater of energy is to the erosion of metal friction surface.
