Abstract
The invention discloses synthetic fire-resistant hydraulic oil and a preparation method thereof and belongs to the technical field of hydraulic oil. According to the technical scheme, the synthetic fire-resistant hydraulic oil is prepared from, by mass, 98.3-98.8% of saturated polyol ester base oil and 1.2-1.7% of additive. The preparation method comprises the following steps that 1, the additive is added into trihydroxymethylpropyl trioleate, full and even stirring is performed at normal temperature to enable the additive to be completely dissolved so as to obtain premixed oil; 2, pentaerythritol isooctadecanoate is added into the premixed oil, stirring is performed for 20-60 minutes, and filtration and packaging are performed. The synthetic fire-resistant hydraulic oil has the advantages that the anti-oxidation stability is good, the service life is long, and the using cost is reduced; the amount of the additive is small, and the hydraulic oil is biodegradable and is environmentally friendly; the hydraulic oil is good in non-inflammability and wide in application range; the hydraulic oil is simple to prepare and is easily produced industrially.
Description
technical field [0001] The invention relates to a hydraulic oil and a preparation method thereof, in particular to a synthetic fire-resistant hydraulic oil and a preparation method thereof. Background technique [0002] With the widespread use of lubricating oil, lubricating oil can enter the soil and water sources through various improper channels during use. If the lubricating oil entering the soil and water sources cannot be degraded naturally, it will pollute the soil and water sources. At present, Europe and the United States attach great importance to the environmental impact of the use of lubricating oils, and they have formulated corresponding environmental protection regulations to limit the use of non-degradable lubricating oils (mineral oil, phosphate ester and polyether). Therefore, degradable lubricating oil - synthetic ester oil has been well developed and used in European and American countries. As early as in the Eleventh Five-Year Plan, our country put forw...
