Abstract

The invention relates to a compressor oil composition and a preparation method thereof, and relates to the field of industrial lubricating oil. The compressor oil composition comprises the following ingredients in parts by weight: (1) 65 to 80 parts of basic oil; (2) 6 to 12 parts of oily agent; (3) 5 to 10 parts of friction improver; (4) 2.5 to 4.5 parts of elastic macromolecule emulsion; (5) 2.5 to 5 parts of antioxidant corrosion resisting agent; (6) 6 to 12 parts of polyacrylate; (7) 2.2 to 4.2 parts of cleaning agent; (8) 4 to 8 parts of ethylene-bis-stearamide; and (9) 2 to 4 parts of top-grade fatty alcohol. The preparation method of the composition comprises the following steps: (1) weighting; (2) pre-mixing; (3) ultrasonically stirring; and (4) standing. According to the compressor oil composition and preparation method thereof, the oil product is high in viscosity index, good in low-temperature starting performance, excellent in lubricating property; and moreover, the oil product is stable in characteristic, high in weather resistance, good in washing dispersing performance and capable of being used for a long time.

Description

technical field [0001] The invention belongs to the field of industrial lubricating oil, in particular to a compressor oil composition used for refrigeration compressor oil and a preparation method thereof. Background technique [0002] Compressor oil is the lubricating oil used by the compressor. Compressor oil can be divided into two categories: one is piston or rotary compressor oil, and the other is refrigeration compressor oil. Refrigeration compressor oil has a series of special requirements. The oil product is in constant contact with the refrigeration medium, and the temperature and pressure of the medium change frequently. Therefore, it is necessary for the compressor oil to have a sufficiently low freezing point, a gentle viscosity-temperature curve and good oxidation resistance. In addition, corrosion of machine parts by refrigerant and compressor oil must be controlled. [0003] The patent document of "compressor oil composition" with application number 201310...
