Problems solved by technology

[0002] Coal mine equipment has been in the dark, humid, high oil temperature, and high load for a long time without interruption. As far as the oil used for the equipment is concerned, most of them choose the corresponding similar lubricating oil equivalently according to the state of the friction pair; sometimes it is very It is difficult to meet the requirements of high oil temperature, high load and long-term operation of the equipment; therefore, choose a reasonable lubrication method and select a special lubricant composed of a suitable formula

Embodiment

[0018] 1. First install and debug equipment, mainly including raw material storage tanks, finished product storage tanks, blending kettles, heating equipment and laboratory equipment;

[0019] 2. Carry out laboratory tests on relevant indicators of raw materials, and feed materials only after passing the test;

[0020] 3. Heat 5% diluent oil to 55-65°C, then add 27% diheptyl diphenylamine in proportion, and stir at constant temperature for no less than 20 minutes;

[0021] 4. Then add 20% octadecyl carbamate, 12% modified petroleum calcium sulfonate, and 17% borated polyisobutylene bis-succinimide in proportion, and stir a lot at 55-65°C in 30 minutes;

[0022] 5. Finally, add 19% of zinc di-tertiary alkyl dithiophosphate in proportion and stir at a constant temperature of 55-65°C for 30 minutes to get the finished product, and the product can be obtained after the finished product passes the inspection.

Abstract

The invention discloses a novel special lubricating oil additive for a coal mine pressure fan and a preparation method thereof. The novel special lubricating oil additive for the coal mine pressure fan provided by the invention is composed of 27% of diheptyl diphenylamine, 20% of octadecyl carbamate, 17% of boronized polyisobutene bis-succinimide, 12% of modified petroleum calcium sulfonate, 19% of di-tert-alkyl zinc dithiophosphate and 5% of diluted oil, wherein diheptyl diphenylamine, octadecyl carbamate, boronized polyisobutene bis-succinimide, modified petroleum calcium sulfonate, di-tert-alkyl zinc dithiophosphate and diluted oil need to reach the standards of industrial-grade qualified products or above. The special lubricating oil additive provided by the invention is used in lubricating oil of a mine pressure fan system, and effectively guarantees that a device can reliably operates for a long term under the states of high oil temperature, high load and no interruption.

Description

technical field [0001] The invention relates to a fine chemical product, in particular to a novel compound additive for lubricating oil for a coal mine compressor and a preparation method thereof. Background technique [0002] Coal mine equipment has been in the dark, humid, high oil temperature, and high load for a long time without interruption. As far as the oil used for the equipment is concerned, most of them choose the corresponding similar lubricating oil equivalently according to the state of the friction pair; sometimes it is very It is difficult to meet the requirements of high oil temperature, high load and long-term operation of the equipment; therefore, choose a reasonable lubrication method and select a special lubricant composed of a suitable formula. In particular, long-life and high-efficiency lubricating oil is a major trend in equipment lubrication demand in the future. The recent promulgation and implementation of more stringent encircling regulations has...
