Problems solved by technology

Another example: the application number is: 02111966.X. After the running-in is over, that is, after the irreversible reaction at the highest peak point stops, although the inert anti-wear component immediately forms a chemical adsorption film, there is a relative increase in the anti-fatigue wear characteristics of the engine. Many, while the anti-oxidative decay performance is not high

Embodiment 1

[0021] The formula of running-in agent is: (by weight %)

[0022] Phosphazene 9

[0023] C 12 -C 18 Organic amine salt 7

[0024] Thiadiazole Derivatives 5

[0025] Zinc tertiary alkylthiophosphate 9

[0026] Calcium Alkyl Salicylate 6

[0027] Succinimide dispersant and diester oil 64

[0028] Phosphazene, C 12 -C 18 Organic amine salt, thiadiazole derivatives, tertiary alkyl zinc thiophosphate, calcium alkyl salicylate, succinimide dispersant and diester oil are mixed and dissolved at 56°C to make a running-in agent.

[0029] At normal temperature, the prepared running-in agent is added into the base lubricating oil at a ratio of about 4% by weight, mixed and stirred for 1.8 hours, and filtered to become the running-in lubricating oil.

Embodiment 2

[0031] The formula of running-in agent is: (by weight %)

[0032] Phosphazene 9.5

[0033] C 12 -C 18 Organic amine salt 9

[0034] Thiadiazole Derivatives 6

[0035] Zinc tertiary alkylthiophosphate 11

[0036] Calcium Alkyl Salicylate 6.5

[0037] Succinimide dispersant and diester oil 58

[0038] Phosphazene, C 12 -C 18 Organic amine salt, thiadiazole derivatives, tertiary alkyl zinc thiophosphate, calcium alkyl salicylate, succinimide dispersant and diester oil are mixed and dissolved at 60°C to make a running-in agent.

[0039] At normal temperature, the prepared running-in agent is added into the base lubricating oil at a ratio of about 5% by weight, mixed and stirred for 1.5 hours, and filtered to become the running-in lubricating oil.

Embodiment 3

[0041] The formula of running-in agent is: (by weight %)

[0042] Phosphazene 10

[0043] C 12 -C 18 Organic amine salt 10

[0044] Thiadiazole Derivatives 7

[0045] Zinc tertiary alkylthiophosphate 11

[0046] Calcium Alkyl Salicylate 7

[0047] Succinimide dispersant and diester oil 55

[0048] Phosphazene, C 12 -C 18 Organic amine salt, thiadiazole derivative tertiary alkyl zinc thiophosphate, calcium alkyl salicylate, succinimide dispersant and diester oil are mixed and dissolved at 65°C to make a running-in agent.

[0049] At normal temperature, the prepared running-in agent is added to the base lubricating oil at a ratio of about 6% by weight, mixed and stirred for 2 hours, and filtered to become the running-in lubricating oil.

[0050] In order to exert its maximum special effect, the running-in lubricating oil must be properly matched with the main parameters of the actual diesel engine and gasoline engine: load, speed, and time. The selection of matching par...

Abstract

This invention discloses a kind of lubricating oil additive and the preparation method of it. The following are the components of the additive (calculated by the weight): The proportion of phosphonitrile is 9-10%, that of C12-C18 organic amine salt is 7-11%,that of the derivant of thiadiazole is 5-7%,that of tertiary alkylthioalkyl zinc phosphate is 9-13%, that of alkyl calcium salicylate is 6-7%,that of the succimide dispersant agent and di-esters oil is 55-65%,The derivant of thiadiazole, preparation method is as following: The phosphonitrile, C12-C18 organic amine salt, tertiary alkylthioalkyl zinc phosphate, alkyl calcium salicylate, succimide dispersant agent and di-esters oil are combined and resolved, and then agitate it for 1.5-2.0h.The obvious excellence showed after using the method is the running-in period is short, the running-in Quality and the fatigue resistance will be improved obviously, hard running-in can be leaved out, the overhaul ratio of the whole machine can be decrease 60%, the benefit of economy and society is outstanding.

Description

1. Technical field: [0001] The invention relates to a formula of running-in lubricating oil and a running-in agent and a preparation method thereof, relates to a formula of a lubricating oil running-in agent in the running-in process of an engine and a preparation method thereof, and belongs to the technical field of lubricating oil. 2. Background technology: [0002] Lubricating oils used for engine running-in in the prior art are divided into two categories: one is the running-in oil with high sulfur content and high group ratio of sulfur-containing compounds or vulcanized oil as the main component. It can make the microscopic peak point of the friction pair surface have a certain protection, which is not conducive to the increase of the actual contact area of ​​the friction pair surface after running-in, and is prone to fatigue points, which is not conducive to the extension of the service life of the engine after running-in. The material is unfavorable, and it is easy to...
