The invention provides synthetic water-soluble industrial gear oil and a preparation method thereof. The total amount of water-soluble polyether is 100 parts by weight, 20%-30% of the total amount ofthe water-soluble polyether is added into a product kettle and preheated to reach the temperature of 75-90 DEG C, antifriction antirust additives and copper corrosion inhibitors are metered and addedinto the product kettle, constant-temperature stirring is performed for 25-35 minutes until the antifriction antirust additives and the copper corrosion inhibitors are completely dissolved, the residual water-soluble polyether is metered and pumped into the product kettle, and high-temperature antioxidants, extreme pressure anti-wear additives, chlorinated paraffin hydrolysis inhibitors, hydrogenion catching agents and defoaming agents are sequentially metered and added into the product kettle and uniformly stirred to obtain the water-soluble industrial gear oil. The synthetic water-soluble industrial gear oil is good in use safety and antifriction and anti-wear properties, excellent in water capacity, strong in corrosion resistance, excellent in oxidation stability and heat stability andparticularly applicable to lubrication of a speed reducer gear box working in a water vapor environment, energy is saved, and emission is reduced.
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...
