Problems solved by technology

However, increasing the working temperature will also deteriorate the working condition of the lubricating oil. At present, the technology of railway diesel locomotive oil is still relatively lagging behind, and there is no oil product designed for harsh working conditions, so there is no way to meet the needs of locomotives to increase the working temperature and in It is also prone to problems when used in summer, deserts, and low-latitude areas
[0003] Document CN200310104206 discloses a lubricating oil for internal combustion engines of railway locomotives, which has good anti-wear extreme pressure function, but does not solve the problem of easy oxidation and failure of oil products at high temperatures

Embodiment 1～4

[0027] Add each component according to the parts by weight in Table 1, and mix uniformly to obtain a compound agent composition for railway diesel locomotive oil.

[0028] The composition obtained in [Example 1-4] was added to the base oil at 65°C with the dosage shown in Table 2, wherein the nitrogen-containing ashless dispersant used was T154 double polyisobutylene succinimide, and the phosphorus-containing The anti-wear agent is T203 bis-octyl zinc thiophosphor, stirred for 3 hours, made into a sample, and carried out performance evaluation. The results are shown in Table 2.

Abstract

The invention relates to a railroad internal combustion engine car oil complexing agent composition and application thereof. The railroad internal combustion engine car oil complexing agent composition is prepared from, by weight, 20-70 parts of metal detergent, 10-50 parts of nitrogen-contained ash-free dispersing agent, 5-30 parts of phosphorus-contained anti-wear preservatives and 5-30 parts of complex antioxidant, wherein metal detergent is prepared from sulfonate, sulfurated alkyl phenate and salicylate, and the complex antioxidant is prepared from aryl sulfide antioxidant, phenolic antioxidant and amino thio ester. The composition can be used for industrially producing railroad internal combustion engine car oil.

Description

technical field [0001] The invention relates to a railway diesel locomotive oil compounding agent composition and its application. Background technique [0002] Energy saving and environmental protection are the current trend of technological development. The working temperature of diesel locomotives is controlled by the cooling water system. If the set working temperature is low, a large amount of heat energy will be consumed by the cooling water, so raising the working temperature of the locomotive can save Lots of energy. However, increasing the working temperature will also deteriorate the working condition of the lubricating oil. At present, the technology of railway diesel locomotive oil is still relatively lagging behind, and there is no oil product designed for harsh working conditions, so there is no way to meet the needs of locomotives to increase the working temperature and in It is also prone to problems when used in summer, deserts, and low-latitude areas.
