Problems solved by technology

Through domestic and foreign patent inquiries, no public patents and materials with relevant content have been found. According to domestic literature and materials, Nanjing Edison Company's medium-duty industrial gear oil compounding agent has a dosage of 1.4wt%, which is limited to modulation of medium-duty Industrial gear oils cannot be used to prepare heavy-duty industrial gear oils. For the compound agent for medium and heavy-duty industrial gear oils of the patent CN1403551A, the dosage is 1.2-2.0 wt%, and the phosphorus content of the compound product is 1.5-2.5 wt%.

Abstract

The invention provides an additive composite for general industrial gear lubricants, comprising (A) at least one type of extreme pressure and anti-wear additive with sulfurs, (B) at least one type of multi-functional anti-wear additive with phosphors, and (C) at least one type of anti-rusting agent. The composite has the advantages of lower levels of additive, simple formula, strong universality and excellent performance. By adding the additive composite into base oil with medium viscosity index or high viscosity index or into a mixture of the base oil according to weight percentage between 0.6 and 1.0, a medium-duty industrial gear oil up to the indexes of GB5903-95 standards, such as the number 100, 220,320, 460,680 and1000, is prepared. By adding the additive composite into base oil with medium viscosity index or high viscosity index or into the mixture of the base oil according to the weight percentage between 1.0 and 1.4, a heavy-duty industrial gear oil up to the indexes of GB5903-95 standards, such as the number 100, 220,320, 460,680 and1000, is prepared.

Description

(1) Technical field [0001] The invention relates to a general industrial gear lubricating oil additive composition, in particular to an additive composition for lubricating oil used in industrial gear transmission systems, and belongs to the technical field of lubricating oil additives. (2) Background technology [0002] General-purpose industrial gear oil compounding agent is a compounding agent used to prepare medium and heavy-duty industrial gear oils of various viscosity grades, and its dosage is one of the most important indicators to measure the level of the compounding agent and its technical and economical efficiency. Through domestic and foreign patent inquiries, no public patents and materials with relevant content have been found. According to domestic literature, Nanjing Edison Company's medium-duty industrial gear oil compounding agent has a dosage of 1.4wt%, which is limited to modulation of medium-duty Industrial gear oils cannot be used to modulate heavy-duty...
