Problems solved by technology

[0003] In order to meet the performance requirements of high-quality refrigeration compressor oil and reduce the dependence on naphthenic oil and the consumption of petroleum resources, which is beneficial to environmental protection, people have developed many refrigeration oils for refrigeration compressors. However, these refrigeration oils have many The problem is that the miscibility of some refrigerating machine oils and refrigerants is not good enough, which affects the working performance of the compressor; some refrigerating machine oils have poor chemical stability and thermal oxidation stability, and are easy to decompose to produce acidic substances that corrode metal parts; some refrigerating machine oils The hydrolytic stability and electrical insulation are poor, which affects the normal operation of refrigeration compressors; some refrigeration oils lack good anti-friction and lubricating properties

Embodiment 1

[0021] The specific preparation method is as follows:

[0022] a) Preparation of base oil, the preparation of base oil includes preparation of hydrogenated tea oil and blending. Among them, the process of preparing hydrogenated tea oil is as follows: first, the tea seed oil is washed, rolled, fried, and pressed under the condition of strict control of moisture and temperature to obtain crude oil; then the crude oil is subjected to alkali refining, decolorization, deodorization, Filtration and other refining, then enter the hydrogenation tank for treatment, and then filter to obtain hydrogenated camellia oil. When blending the ratio, blend the diester-type synthetic oil and hydrogenated tea oil at a mass ratio of 5:1.

[0023] b) Heating treatment of base oil. The treatment process is as follows: the base oil with a weight percentage of 91% is sent into the blending kettle with a gear pump, and after evacuation, stirring and heating processes, the temperature is raised to 85°C...

Abstract

The invention provides biodegradable machine oil for a refrigerating compressor and a preparation method thereof. The biodegradable machine oil contains the ingredients in percentage by weight: 91-95% of base oil, 1-2% of antioxidant, 0.5-1% of antifoamer, 0.5-1% of anti-emulsifier, 2-3% of metal passivator and 1-2% of rust preventer. The preparation method of the biodegradable machine oil comprises the steps of (a) preparing the base oil; (b) carrying out heating treatment on the base oil; (c) carrying out additive adding treatment. According to the biodegradable machine oil for the refrigerating compressor and the preparation method thereof, provided by the invention, the biodegradable machine oil is reasonable in proportion and simple and convenient in preparation, has relatively high natural degradability, can be excellently dissolved with a refrigerant of the compressor and has relatively good oxidation, rusting, wearing and hydrolysis resistance, so that the requirements of the refrigerating compressor for high performance are met.

Description

technical field [0001] The invention relates to a compressor, in particular to a biodegradable engine oil used in a refrigeration compressor and a preparation method thereof, belonging to the technical field of compressors. Background technique [0002] The refrigeration compressor is one of the most important equipment in the refrigeration system. As the main component of the refrigeration system, the refrigeration compressor oil directly determines and affects the function and effect of the refrigeration device. At present, refrigeration compressor oil is mainly made of mineral naphthenic oil as base oil and some additives. With the continuous development of various refrigeration equipment and device manufacturing technologies, refrigeration compressors tend to be energy-saving, high-efficiency, high-speed, small and light-weight, fully enclosed and long-life. Since freon-based refrigerants widely used in refrigeration and air-conditioning will cause the destruction of th...
