preparation example Construction

[0049] The present invention also provides a kind of preparation method of elevator oil composition, comprises the following steps:

[0050] (A) Mix and prepare polyalkylene glycol and co-solvent to obtain mixed oil;

[0051] The co-solvent is one or more of alkylated aromatic esters and C5-C25 fatty acid esters, the content of which is 2%-25% of the mass of polyalkylene glycol;

[0052] (B) mixing the mixed oil with an extreme pressure antiwear agent, a metal rust inhibitor, a metal deactivator, an antioxidant and a defoamer to obtain an elevator oil composition;

[0053] The extreme pressure antiwear agent is one or more of phosphorus-containing type and sulfur-phosphorus type extreme pressure antiwear agent, and its content is 0.3%~3% of the mass of polyalkylene glycol;

[0054] The content of the metal antirust agent is 0.01% ~ 0.2% of the polyalkylene glycol quality;

[0055] The content of the metal deactivator is 0.01%~0.2% of the polyalkylene glycol mass;

[0056] T...

Embodiment 1

[0062] Add 100 kg of polyalkylene glycol and 15 kg of pentaerythritol tetra-n-heptanoate into a mixing tank with a stirrer, stir at 55° C. for 4 hours, and prepare a mixed oil. The kinematic viscosity of polyalkylene glycol at 40°C is 200mm 2 / s.

[0063] Add 1.5 kg of tricresyl phosphate, 0.07 kg of oleoyl amino acid, 0.07 kg of benzotriazole derivatives, 0.8 kg of dialkyl diphenylamine, 0.8 kg of 3,5-di-tert-butyl-4- Hydroxyphenyl acetate and 400ppm methyl silicone oil were uniformly mixed to obtain an elevator oil composition.

[0064] The obtained elevator oil composition was tested for performance, and the results are shown in Table 1. Table 1 shows the performance parameters of the elevator oil composition prepared in Example 1 and Example 3.

Embodiment 2

[0066] Add 100 kg of polyalkylene glycol and 20 kg of pentaerythritol tetra-n-heptanoate into a mixing tank with a stirrer, stir at 60° C. for 3.5 hours, and prepare a mixed oil. The kinematic viscosity of polyalkylene glycol at 40°C is 600mm 2 / s.

[0067] Add 1.8 kg of tricresyl phosphate, 0.05 kg of oleoyl amino acid, 0.15 kg of benzotriazole derivatives, 1 kg of dialkyl diphenylamine, 1 kg of 3,5-di-tert-butyl-4- Hydroxyphenyl acetate and 300ppm methyl silicone oil were uniformly mixed to obtain an elevator oil composition.

Abstract

The invention provides an elevator oil composition, which comprises polyalkylene glycol, a latent solvent, an extreme pressure anti-wear additive, a metal anti-rusting agent, a metal deactivator, an antioxidant and a defoaming agent. A preparation method of the elevator oil composition comprises the following steps of: blending the polyalkylene glycol and the latent solvent to obtain mixed oil; and mixing the mixed oil with the extreme pressure anti-wear additive, the metal anti-rusting agent, the metal deactivator, the antioxidant and the defoaming agent to obtain the elevator oil composition. The elevator oil composition provided by the invention has superior oxidation stability, superior lubricating performance, extreme pressure anti-wear property, corrosion and rust resistance and defoaming resistance, and is particularly suitable for worm and gear tractor of which a transmission position is in a boundary lubricating state frequently; and an oil film can be formed rapidly, the operation temperature is lowered, energy is saved, the consumption is lowered, the transmission efficiency of the tractor is increased, and metal wear is reduced.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to an elevator oil composition and a preparation method thereof. Background technique [0002] An elevator is a means of transportation powered by an electric motor, which can transport a large number of people and goods. It is often used in shopping malls, residences, subways, airports and other public places where the flow of people is relatively concentrated. With the high development of modern cities, elevators have gradually become an indispensable part of people's daily production and life. [0003] The elevator is mainly composed of traction machine, guide rail, counterweight device, safety device, signal control system, car, hall door and other components. The traction machine is one of the key components that affect the stable operation of the elevator. The main types of traction machines are worm gear traction machines driven by asynchronous motors and permanent magnet syn...
