[0021] The preparation method of the repairing energy-saving and environmental protection engine protective agent of the present invention includes the following steps:

[0022] 1) Synthesis of mixed ester

[0023] Put oleic acid, sebacic acid and ethanol in a container, react at 250℃~260℃ for 2~3 hours under nitrogen protection, then add dodecylphenol, adjust the temperature to 180℃~ under the high negative pressure of 80mmHg Continue the reaction at 190°C for 2 to 3 hours, then adjust the negative pressure to a high of 50mmHg, and the temperature remains unchanged. Continue the reaction for 2 to 3 hours to obtain a mixed ester; the weight ratio of oleic acid, sebacic acid, ethanol, and dodecylphenol =2~3: 2~3:1~2:1~2;

[0024] 2) Synthesis of repairing energy-saving and environmentally friendly engine protective agent

[0025] Mix the above-prepared mixed ester with alkyl diphenylamine, molybdenum oxide, and sodium tungstate, stir evenly, add dodecanol, and react for 4 to 5 hours u...

Abstract

The invention discloses a restoration type energy-saving environment-friendly engine protection agent and a preparation method thereof. The protection agent is prepared from mixed ester, alkyl diphenylamine, molybdenum oxide, sodium tungstate, dodecanol and hexanedioic acid according to a weight ratio of 100:(7 to 9):(7 to 9):(20 to 25):(10 to 12):(10 to 12); the mixed ester is prepared from oleic acid, sebacic acid, ethyl alcohol and dodecylphenol through reaction. An additive is an oil-soluble restoration type energy-saving environment-friendly engine protection agent, and is a friction modifier, an antiwear agent and an antioxidant for lubricating oil, particularly lubricating oil for an internal combustion engine; the oil-saving effect is obvious; no sulfur and no phosphorus are contained, so that the additive also has the advantages of being energy-saving and environmentally friendly.

Description

Technical field [0001] The invention relates to a lubricating protective agent, in particular to a repairing energy-saving and environmentally friendly engine protective agent and a preparation method thereof. Background technique [0002] With the rapid development of international industry, more stringent requirements for high speed and high load of mechanical equipment have been increased. However, the traditional lubrication method still stays on the oil film lubrication, which has caused the engine to intensify the wear and tear, and while the energy has suffered huge losses, it also caused serious pollution and damage to the environment. [0003] As China with the largest car ownership, energy saving and emission reduction are the top priorities. [0004] Repairing engine protective agent breaks the traditional lubrication method of lubricating a single oil film, and integrates multiple lubrication principles such as physical film, chemical film, and multi-element metal permea...
