Problems solved by technology

[0004] Chinese patent application number: 200810241687.2 discloses a lubricating oil containing base oil, detergent and dispersant, with or without auxiliary additives. Although the lubricating oil can reduce the amount of sludge generated during engine use, it cannot prevent The wear, stability, and oxidation stability of the engine are also average, which cannot meet the requirements of long-term field operation of construction machinery, complex working conditions, heavy heat load, and frequent oil changes.

Embodiment 1

[0017] The raw materials in this example include base oil and additives. The base oil includes hydrogenated mineral base oil 650SN and bright stock 150BS; the additive includes complex agent H8744B, viscosity index improver OCP, pour point depressant 1-248 and anti Foaming agent T901; the mass percentage of each component in the raw material is: hydrogenated mineral base oil 650SN is 72.5%, bright stock 150BS is 5%, compounding agent H8744B is 13%, viscosity index improver agent OCP is 9%, pour point depressant Agent 1-248 is 0.5%, antifoaming agent T901 is 0.001%.

[0018] The composite agent H8744B of the present invention is a high-performance multi-purpose engine oil composite additive. Its main components are calcium, molybdenum, nitrogen, and zinc. It applies a new type of ashless dispersant and all-calcium-based detergent. Excellent cleaning and dispersing properties, effectively reducing carbon deposits, excellent lubricity and extreme pressure resistance, greatly red...

Embodiment 2

[0030] The present invention can adjust the mass percentages among the components according to actual needs, see Table 1.

[0031] Table 1 The mass percent of each composition of other embodiment of the present invention

Abstract

The invention relates to a formula of special lubricating oil for engineering machinery and a production process of the lubricating oil. The lubricating oil is prepared from base oil and additives as raw materials, wherein the base oil comprises mineral base oil and synthetic base oil, namely, imported hydrogenated mineral base oil 650SN and bright oil 150BS; the additives comprise a complexing agent H8744B, a viscosity index improver OCP, a pour point reducer 1-248 and an anti-foaming agent T901; and the base oil and the additives are mixed according to a certain ratio to obtain the lubricating oil. For a power device, which often can operate in the states of high temperature and high load due to relatively poor engineering machinery operating environment and has the characteristics of complicated working conditions, large power, large heat load, high content of sulfur in a fuel and the like, the formula of special novel technology for the engineering machinery is adopted so as to achieve exceptional high temperature detergency and dispersity, the binding of piston ring and polishing of a cylinder liner due to the adoption of direct fuel injection are effectively prevented and the highly cleaning of the engine is retained, the lubricating oil has excellent abrasion resistance compared to the general turbocharged diesel engine oil, the abrasion of engine parts is effectively prevented and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to a formula of special lubricating oil for engineering machinery and a production process thereof. Background technique [0002] The operating environment of construction machinery is relatively harsh, and the construction period is relatively long. They often operate under high temperature and high load conditions, and the operation site does not have relatively complete maintenance conditions. For example, there is a serious shortage of parts that should be equipped. Lubricating oil also has higher requirements under this condition. In the actual operation stage of the project, the lubricating oil should be selected in combination with the actual situation of the job site and the relevant performance of the construction machinery. Daily maintenance and preparations must also be prepared, so that the lubrication of the equipment can wait for the corresponding guarantee, so that the use of construction machinery Life can be exte...
