Description

Technical Field

[0001] The invention relates to the field of protective agents, and more particularly to a protective agent for power equipment. Background Art

[0002] With the rapid development of the automobile industry, especially the continuous innovation and improvement of modern automobile engine technology, the performance requirements of automobile engines are becoming higher and higher. In order to extend the service life of the engine, improve fuel efficiency, reduce emissions, and improve driving experience, the automobile power system needs more sophisticated and efficient protection measures. In this context, automobile power equipment protective agents came into being and became an important part of maintaining the engine and improving the performance of the power system.

[0003] Automotive power protectors are a class of chemical additives specifically designed to protect internal engine components, extend engine life and improve performance. They are usually added to engine oil to help reduce friction, reduce wear, prevent corrosion, clean carbon deposits and gums, and provide additional protection, especially under high loads and harsh environments.

[0004] Although many automotive power protectants have a certain anti-wear effect, some traditional protectants still cannot completely prevent the wear of engine parts under high load and extreme working conditions, especially when running at high speed for a long time or driving long distances. This wear may cause damage to the engine and even affect power output and fuel economy. The base oil of lubricating oil is the key to lubrication performance. The existing solution uses the base oil irrationally, resulting in poor lubricity and pressure resistance of existing automotive power protectants.

[0005] Therefore, it is very necessary to develop an automotive power protective agent with good lubricity, strong compressive resistance and wear resistance. Summary of the invention

[0014] In a preferred embodiment, the antioxidant includes one or more of 2,6-di-tert-butyl-p-cresol, triphenyl phosphate, tert-butylaniline, dibenzothiophene disulfide, and N-nitroso compounds.
