Abstract
A kind of anti-extreme pressure, anti-oxidant lubricating oil recombiner belong to chemical technology field.Its weight proportion is: single alkane substituting group (C
2-18, cyclohexyl) and sulfo-amido formic acid (Dtc) copper 0.1-5%, Dtc-zinc 0-3%, Dtc-molybdenum 0-5%, calcium sulphonate 0-3%, hexene propylene copolymer 0-4%, surplus is a base oil.Its advantage is: contain sulfo-amido formate recombiner and compare with the lubricating oil of sulfur-bearing zinc phosphate (T202) recombiner, the acid number after the former oxidation is the latter's 1/5; Throw out after the former oxidation is the latter's 1/17; Extreme pressure value (tetra-ball machine test method) is two times of the latter.
Description
The invention belongs to chemical technology field.
State development along with transport trade and mechanical industry are fast, the design of metal parts kinematic pair develops to high rotating speed, high loading direction with making.Therefore, the thermal load that friction member bears is increasing, like this high temperature anti-attrition, the high-temperature oxidation resistance of lubricant has been proposed the requirement at tighter quarter.Commercially available auxiliary agent thermotolerances such as organic phenol, organosulfur, organochlorine and amine, resistance to abrasion is difficult to satisfy above-mentioned requirements.Sulphur zinc phosphate (T202) is though thermotolerance is fair, and antioxidant property is not good, and acid number and degree of corrosion are big, and degradation production can cause the exhaust purifier poisoning of catalyst.
The purpose of this invention is to provide a kind of have higher anti-extreme pressure, lubricating oil recombiner that antioxidant property is good.
The technology of the present invention principle is as follows:
Its prescription is: single alkane substituting group (C
2-18, cyclohexyl) and sulfo-amido formic acid (Dtc) copper 0.1-5.0%, Dtc-zinc 0-3%, Dtc-molybdenum 0-5.0%, calcium sulphonate 0-3%, allyl alkene copolymer (T604) 0-4%, surplus is a base oil.Aforementioned proportion is weight ratio.
Its complete processing is: above-mentioned material is dropped in the reactor in proportion mix, be heated to 50-60 ℃, being incubated becomes homogeneous transparent oily product after 30-60 minute.
The present invention's advantage is: the lubricating oil that contains single alkane substituting group sulfo-amido formate recombiner is compared with sulfur-bearing zinc phosphate recombiner person, and the acid number after its oxidation is to contain 1/5 of T202; Throw out after the oxidation is to contain 1/17 of T202; Extreme pressure value (four-ball tester method) is its two times.
Embodiment:
With single alkane substituting group (C
2-18, cyclohexyl) and sulfo-amido Tubercuprose 2Kg, Dtc-zinc 0.2Kg, calcium sulphonate 2.5Kg, allyl alkene copolymer 3.8Kg, base oil (SN200) 91.5Kg, drop in the 300 liter reactors and mix, be heated to 60 ℃, being incubated promptly becomes homogeneous transparent shape compounded lubricating oil after 50 minutes.
