Abstract

The invention belongs to the field of automobile engine lubricating protective agents, discloses an automobile engine protective agent, a preparation method thereof. The protective agent comprises thefollowing components in parts by weight: 70-90 parts of base oil, 0.5-1 part of a thickening agent, 1-5 parts of an antioxidant, 1-5 parts of a dispersing agent, 1-5 parts of a friction reducing agent and 0.1-0.8 part of a pour point depressant, the friction reducing agent is a mixture of an organic molybdenum compound and an ester compound, wherein the organic molybdenum compound is molybdenum dialkyldithiocarbamate or molybdenum dialkyldithiophosphate, the ester compound is glyceryl monooleate or boric acid ester. The protective agent has an excellent friction reducing effect and has an unexpected effect of repairing existing abrasive spots, hard impact during cold start can be effectively reduced, raw materials are easy to purchase, and the process is relatively simple.

Description

technical field [0001] The invention relates to an automobile engine lubricating and protecting agent, in particular to an automobile engine protecting agent and a preparation method. Background technique [0002] With the development of the international automobile industry, the requirements for the protection of the engine are becoming higher and higher, and the lubricating oil for the engine will develop in the direction of low viscosity with the development of the engine. Due to the increasingly stringent environmental protection regulations, It has brought more and more pressure to automobile manufacturers and lubricating oil producers. Extending the service life of the engine has become one of the direct driving forces to promote the improvement of engine technology and the upgrading of lubricating oil. Among them, the wear and tear caused by friction is the engine scrapped One of the main forms is to control and reduce the wear and tear of automobile engines, which ca...
