preparation example Construction

[0039] The present invention also provides a preparation method of lubricating oil for elevator traction machine, comprising:

[0040] Mix and dehydrate 100 parts by weight of PAG base oil, 1-2 parts by weight of antioxidant, 2.0-4.0 parts by weight of extreme pressure anti-wear agent, 1.0-2.0 parts by weight of anti-corrosion agent and 0.005-0.10 part by weight of anti-foaming agent to obtain elevator traction lubricating oil for lead machine;

[0041] Wherein, the antioxidant is obtained by compounding a phenolic antioxidant and an amine antioxidant.

[0042] According to the present invention, 100 parts by weight of PAG base oil, 1-2 parts by weight of antioxidant, 2.0-4.0 parts by weight of extreme pressure anti-wear agent, 1.0-2.0 parts by weight of anti-corrosion agent and 0.005-0.10 part by weight of anti-foaming agent Mixing and dehydration to obtain lubricating oil for elevator traction machine; wherein, the PAG base oil preferably has a kinematic viscosity of 288-35...

Embodiment 1

[0048] Step a) sending 50% by weight of JM-305A and 50% JM-306B into the blending kettle with a gear pump, evacuating, stirring, heating, and heating to 80°C;

[0049] Step b) To the base oil of step a), add 1.0% diisooctyl diphenylamine, 1.0% bisphenol A, 0.3% T706 benzotriazole (T706), 3.0% tricresol phosphate (TCP), 0.8% basic barium dinonylnaphthalene sulfonate (T705), 0.1% 1000# methyl silicone oil antifoaming agent, heat up to 120℃ and dehydrate for 1~2h;

[0050] Step c) Take out a small amount of the oil product obtained in step b), add 0.03% white clay filter aid by weight of all oil products and stir, and carry out cyclic filtration, so that the filter aid forms a filter cake in the filter machine, and then filter the filter in the kettle. The remaining oil is filtered through circulation until the oil is clear and transparent without mechanical impurities, and the lubricating oil for elevator traction machine is obtained.

Embodiment 2

[0052] Step a) The JM-306B with a weight percentage of 100% is sent into the preparation kettle with a gear pump, evacuated, stirred, heated, and heated to 80°C;

[0053] Step b) Add 0.5% benzotriazole dodecylamine, 0.5% antioxidant 1330, 4.0% zinc dialkyldithiophosphate, 0.25% basic dinonylnaphthalene sulfonic acid to the base oil of step a) Barium (T705), 0.75% oleic acid, 0.05% MS-675 modified silicone oil antifoaming agent, heat up to 120°C for dehydration for 1-2h;

[0054] Step c) Take out a small amount of the oil product obtained in step b), add 0.05% of 0.03% of the weight of all oil products and stir, and carry out circulating filtration, so that the filter aid forms a filter cake in the filter machine, and then the remaining oil in the kettle is removed. The lower oil is circulated and filtered until the oil is clear and transparent without mechanical impurities, and the lubricating oil for elevator traction machine is obtained.

Abstract

The invention provides lubricating oil for elevator traction machines. The lubricating oil comprises, by weight, 100 parts of PAG base oil, 1-2 parts of antioxidant, 2.0-4.0 parts of anti-wear reagent at extreme pressure, 1.0-2.0 parts of anticorrosive agent and 0.005-0.10 part of antifoaming agent, wherein the antioxidant is compounded by a phenolic antioxidant and an amine antioxidant. The lubricating oil has the advantages that the PAG base oil, the anti-wear reagent at extreme pressure, the anticorrosive agent and the antifoaming agent are combined to prepare the lubricating oil, the obtained lubricating oil can form an extremely strong oil film on the surface of metal when the lubricating oil is used in a toothed elevator traction gearbox, a good anti-wear feature is achieved, the lubricating requirements of the worm gear and worm gearbox of the steel-copper friction pairs of an elevator traction machine can be satisfied by adding the specific antioxidant composition, and the lubricating oil is good in lubricating performance, low-temperature flowability and thermal oxidation stability and applicable to the lubricating of escalator chains.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a lubricating oil for an elevator traction machine and a preparation method thereof. Background technique [0002] The main components of various elevators are different, but they usually include eight major components: traction system, guidance system, car, door system, weight balance system, electric traction system, electrical control system, and safety protection system. There are many parts in elevator equipment that need to be lubricated, mainly including traction gear box, wire rope, guide rail, hydraulic buffer and car door operator. Among them, the elevator traction machine is the power equipment of the elevator, also known as the elevator host. The function is to convey and transmit power to make the elevator run. It consists of electric motor, brake, coupling, reduction box, traction sheave, frame and guide wheel and auxiliary turning handwheel. [0003] In the domest...
