Abstract
Description
Technical field:
[0001] The invention relates to an extreme pressure anti-oxidation lubricating oil additive of arginine triazine derivatives. The arginine triazine derivatives synthesized by a new method are used as lubricating oil (grease) additives and have excellent extreme pressure anti-oxidation properties . Background technique:
[0002] As we all know, zinc dialkyldithiophosphate (ZDDP) is a commonly used and very effective multi-functional lubricant and grease additive, but because the zinc element in ZDDP is prone to galvanic corrosion, and the phosphorus element in ZDDP is easy to make Catalyst poisoning in automobile exhaust treatment devices. Therefore, in recent years, the search for "phosphorus-free" and "zinc-free" high-efficiency multifunctional lubricant additives that can replace ZDDP has become a current hot research topic.
[0003] Studies have shown that some derivatives containing arginine functional groups {such as: MoDTC, (BMDTC)} has good oxidati...
