Provided are a synthetic industrial gear oil with a water-holding property and a preparation method therefor. The method comprises, with the total amount of the water soluble polyether being 100 parts, taking, in parts by weight, 20-30% of the total amount of a water soluble polyether and adding same to a product kettle and preheating same to 75-90ºC; metering an anti-friction and anti-rust additive and a copper corrosion inhibitor into the product kettle, and stirring same at a constant temperature for 25-35 min, until the anti-friction and anti-rust additive and the copper corrosion inhibitor are dissolved completely; and metering and pumping the remaining water soluble polyether into the product kettle, successively metering a high temperature antioxidant, an extreme pressure anti-wear additive, a chlorinated paraffin hydrolysis inhibitor, a hydrogen ion capturing agent and a defoaming agent into the product kettle, and stirring same uniformly to obtain the industrial gear oil with a water-holding property. The present invention has a good safety in use, good anti-friction and anti-wear properties, an excellent water water-holding capacity, a strong corrosion resistance, excellent oxidation stability and thermal stability, and energy-saving and emission reduction, and is especially suitable for lubrication of the reduction gear box when working in a water vapor environment.
Description
technical field [0001] The invention relates to a synthetic water-tolerant industrial gear oil and a preparation method thereof, belonging to the technical field of chemical material combination. Background technique [0002] In many industrial fields such as oil refineries, chemical plants, mines, docks and oil fields, there are many outdoor reducer gearboxes, which have been exposed to wind and rain for years, and are very easy to enter water. [0003] In addition, many reducer gearboxes in steel plants are always in the environment of water and water vapor. The water ingress in the gearboxes causes the reducer to not operate normally. Therefore, water ingress in the gearboxes is also a very troublesome problem for steel plants. [0004] Currently, mineral or oil-soluble synthetic industrial gear oils are commonly used in gearboxes in these working environments. Because the gear box in the above working environment is very easy to enter water, it will lead to emulsificati...
