Description
One, technical field: the present invention relates to a kind of grease manufacture technology, especially lubricating 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 lubricating grease and preparation method that can satisfy special mechanical, 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 A1 2300kg
The low 3400Kg that coagulates of HVI650 dewax
Calcium hydroxide (85%) 20kg
Lithium hydroxide 61kg
Stearic acid 35kg
Tritolyl phosphate (TCP) 62kg
Ten dihydroxystearic acid 500kg
Benzene-80 45kg of department

Rust-preventive agent T706 2.5kg
Extreme pressure anti-wear additives (T321) 88Kg.
The preparation method: the first step feeds intake, closing presure still and circulation line pipe valve, drop into 2000Kg and press still oil (lithium series base oil A1), open bottom wing, interior outer wing stirs 45-50Hz, and heating agent is controlled at 260-280 ℃, and temperature rises to 60-70 ℃, drop into ten dihydroxystearic acid 400kg stearic acid 35kg, lithium hydroxide 61kg (aqueous solution 100Kg) calcium hydroxide (85%) 20kg (aqueous solution 100Kg).
The second step reaction is warming up to 90-100 ℃, tightens pressure kettle cover screw, closes pressure release valve and import machine oil valve, and outer wing stirs 45-50Hz in opening, the beginning increasing temperature and pressure, and heating agent was controlled at 260-280 ℃, 125-130 ℃ of constant temperature 150 minutes.Constant temperature begins the pressure release that heats up after finishing.(control pressure release top pressure≤0.55Mpa, temperature is not higher than 135 ℃ after the pressure release, heating agent is controlled at 260-280 ℃) is after pressure release is 0,140-145 ℃ of constant temperature 50 minutes.
The 3rd step heated up, and began after constant temperature finishes to continue to heat up, and heating agent is controlled at 260-280 ℃.Be warming up to 150-160 ℃, drop into 300Kg and heat up oily (lithium series base oil A1), temperature rises to 214-216 ℃, constant temperature 10 minutes.Constant temperature is poured material into cooling reactor rapidly through 40 order filtering nets after finishing, the end of falling still back 150Kg (the HVI650 dewax is low to coagulate) pipeline purging.
The cooling of the 4th step heats up, cooling reactor is before batch turning, the low 100Kg with fixed attention of adding HVI650 dewax washes still oil and is warming up to 60-70 ℃, after pouring into by autoclave pressure, cooling, and by 60 order filtering net continuous filtrations 60 minutes, when refiltering 30 minutes, cone penetration is surveyed in sampling, according to the cone penetration situation, and the usefulness of coagulating the soup (HVI 650 dewaxs are low to coagulate) 600Kg-750Kg, when temperature is reduced to 130-140 ℃, free soda acid (being controlled at neutral little acid-0.38% oleic acid) (with stearic acid or lithium hydroxide adjustment) is surveyed in sampling, and acid adjustment is used 80 order filtering net continuous filtrations 60 minutes instead after finishing.
The 5th step is thick to add the agent aftertreatment, filters after 60 minutes, and temperature is reduced to 110-120 ℃, and homogeneous is poured the finished product still into, (homogenization pressure is 20-22Mpa).Homogeneous 30 minutes is opened circulating water cooling, and sampling survey cone penetration, according to the cone penetration situation, and the usefulness of coagulating the soup (the HVI650 dewax is low to coagulate).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 (the HVI650 dewax hangs down and coagulates).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 186kg (pressing base oil 2% increase and decrease);
Tritolyl phosphate (TCP) 62kg (pressing base oil 0.5% increase and decrease);
Extreme pressure anti-wear additives (T321) 88Kg (pressing base oil 1% increase and decrease)
Benzene-80 45kg of department (pressing base oil 0.5% increase and decrease)
After adding the agent end, stir adding in 20 minutes:
Stirred 60 minutes with the low rust-preventive agent T7062.5kg circulation of dissolving with fixed attention of HVI650 dewax, cone penetration is surveyed in sampling, according to the cone penetration situation, the usefulness of coagulating the soup in proportion (lithium series base oil A3), after cone penetration is suitable, the double pump degassing 60 minutes, (roughness of observing oil product again in the degasification process; Impurity; Color; Bubble) degassing is after 60 minutes, and sampling is surveyed dropping point greater than 185 ℃ of H.[2T cone penetration 290-320; No. 1 cone penetration 320-340].
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.
