Problems solved by technology

[0011] However, due to the harsh operating conditions of the oil-injected screw air compressor, factors such as high temperature, high pressure, and water cause rapid oxidation and deterioration of the compressor oil, so the current oil change cycle of the compressor oil is relatively short. 3,000 hours, up to 8,000 hours for synthetic compressor oil, cannot guarantee the long-term and stable operation of the air compressor; at the same time, due to the short oil change cycle, the amount of waste oil produced is also large, which also causes great pressure on environmental protection

preparation example Construction

[0095] According to one aspect of the present invention, a kind of preparation method of above-mentioned compressor oil, described preparation method comprises the following steps:

[0096] (a), mixing phenolic antioxidants, amine antioxidants, metal deactivators, rust inhibitors and defoamers to prepare antioxidant additives;

[0097] (b), mixing long-chain synthetic hydrocarbons, polyol esters, benzoate compounds and benzene ring-containing synthetic hydrocarbons to obtain base oil;

[0098] (c), the base oil obtained in step (b) is dehydrated, then mixed with the antioxidant additive obtained in step (a) to obtain air compressor oil;

[0099] The order of step (a) and step (b) can be reversed.

[0100] The preparation method of compressor oil provided by the present invention, described preparation method is to make antioxidant additive by mixing phenolic antioxidant, amine antioxidant, metal deactivator, antirust agent and defoamer; Simultaneously Long-chain synthetic hy...

Embodiment 1

[0113] A kind of compressor oil, the preparation method of described compressor oil comprises the following steps:

[0114] (1) Add 48.098kg polyalphaolefin (SpectroSyn10, ExxxoMobil), 20kg polyol ester (Pr.3970, Croda), 20kg trimellitate (Pr.1942, Croda) and 10kg alkylnaphthalene to the mixing kettle (Synesstic AN5, ExxonMobil), mixed and stirred to obtain base oil;

[0115] (2) Under a nitrogen atmosphere, heat the base oil to 100°C, vacuum -0.07Mpa, and dehydrate for 1 hour. When the water content in the base oil is detected to be lower than 100ppm, cool the base oil to 70°C to obtain the dehydrated base oil;

[0116] (3) In the above base oil, add phenolic antioxidant L135 (BASF) 0.5kg, L115 (BASF) 0.3kg; amine antioxidant V81 (RT Vanderbilt) 0.4kg, IRGANOX L06 (BASF) 0.6kg Auxiliary antioxidant Irgamet39 (BASF) 0.05kg; Rust inhibitor IrgacorL12 (BASF) 0.05kg; Non-silicon defoamer Synative AC AMH2 0.002kg, stirred evenly, filtered to obtain compressor oil.

Embodiment 2

[0118] This example is the same as Example 1 except that the amine antioxidant IRGANOX L06 (BASF) is not included.

[0119] This example does not contain the amine antioxidant IRGANOX L06 (BASF). IRGANOX L06 (BASF) is an ashless high-temperature antioxidant, which has a low tendency to form sludge and effectively controls the increase in viscosity of air compressor oil due to oxidation. .

Abstract

The invention provides compressor oil as well as a preparation method and application thereof, and relates to the technical field of hydraulic grease; the compressor oil comprises a base oil and an antioxidant additive. The base oil is mainly composed of long-chain synthetic hydrocarbon, polyol ester, benzoate compounds and benzene ring-containing synthetic hydrocarbon; the antioxidant additive ismainly composed of a phenol antioxidant, an amine antioxidant, a metal deactivator, an antirust agent and a defoaming agent. According to the compressor oil, the preparation method and the application thereof, all the components are deeply studied, and the physicochemical properties and the synergistic effect of all the components are fully utilized, and therefore the performance indexes such asthe oxidation performance and the using effect of the compressor oil are greatly improved. The use test proves that the oil change period of the compressor oil is greatly prolonged, the use efficiencyof the air compressor is further improved, the hazardous waste amount is reduced, and good practicability and comprehensive economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of hydraulic grease, in particular to a compressor oil and its preparation method and application. Background technique [0002] There are centrifugal, reciprocating, rotary and other types of air compressors. Because the rotary screw compressor has small size, compact structure, light weight, low cost, high efficiency, reliable operation, convenient maintenance and low maintenance cost (less mechanical parts ), low noise, and no fluctuations in gas delivery. At present, it is widely used in various industries of the national economy such as steel, petroleum, chemistry, mining, food, and transportation. [0003] Based on stability and reliability considerations, most screw compressors currently use oil injection lubrication in which the lubricating oil is fully in contact with the air. In the oil-injected screw air compressor, the compressor lubricating oil acts as a heat carrier, continuously absorbs the ...
