Problems solved by technology

The high temperature oxidation resistance of oil can be improved by using phenolic amine antioxidant complexes, or adding some phosphorus, sulfur and metal organic compounds, but generally there are cumbersome types of additives, high dosage, low efficiency, or in the While improving the oxidation resistance, it will bring some adverse effects to other properties of the lubricating oil, etc.
[0005] At present, the base oil of domestic air compressor oil is mainly mineral oil, but mineral oil contains more sulfur-containing compounds, oxygen, nitrogen-containing compounds and aromatic ring compounds, and its viscosity-temperature performance is poor during the working process, resulting in Air compressor oil has a shorter lifespan

preparation example Construction

[0031] The present invention also provides a kind of preparation method of air compressor oil, comprises the following steps:

[0032] Mix 85-93% of methyl silicone oil, 2-10% of methylphenyl silicone oil, 1-10% of oily agent and 0.1-3% of corrosion inhibitor, and heat to obtain air compressor oil.

[0033] In the present invention, preferably, methyl silicone oil and methylphenyl silicone oil are mixed to obtain a base oil mixture, and the obtained base oil mixture is mixed with an oiliness agent and a corrosion inhibitor, and heated to obtain an air compressor oil. In the present invention, the type, source and dosage of the methyl silicone oil and methylphenyl silicone oil are consistent with those of the methyl silicone oil and methylphenyl silicone oil in the above technical solution, and will not be repeated here. In the present invention, the mixing method of methyl silicone oil and methylphenyl silicone oil is a method commonly used by those skilled in the art.

Abstract

The invention provides air compressor oil, which comprises the following components by mass: 85-93% of methyl silicone oil, 2-10% of tolyl silicone oil, 1-10% of an oily agent, and 0.1-3% of a corrosion inhibitor. The air compressor oil uses the methyl silicone oil and the tolyl silicone oil in a certain proportion as base oil, so that the air compressor oil has good viscosity temperature properties, even after repeated heating and cooling, air compressor oil metamorphism may not be caused, and the service life of the air compressor oil is prolonged. The experimental results show that, the air compressor oil viscosity index can reach more than 420. In addition, the air compressor oil has good oxidation stability, small volatile and less carbon deposit, can guarantee the viscosity, antioxidant, anti foam, anti corrosion performances required for the normal work of compressors, and has excellent viscosity temperature performance and anti pollution performance.

Description

technical field [0001] The invention belongs to the field of lubricating oil, in particular to an air compressor oil and a preparation method thereof. Background technique [0002] Air compressor is a kind of general-purpose machine widely used, involving almost all fields of national economy and industry, and its consumption and production volume are quite large. To ensure the safe and reliable operation of air compressor, lubrication is one of the important links. [0003] The air compressor uses air compressor oil for lubrication, especially for the screw, bearing, gear and other parts of the air compressor, and through the oil circulation, it can cool, carry heat, clean, seal the screw and the shell. my country's annual consumption of compressor oil is nearly 100,000 tons. At present, the air compressor oil in our country is still dominated by mineral oil, accounting for more than 80%, and the environmental pollution is serious. In recent years, with the enlargement of...
