It is an object of the present invention to provide a practical lubricant composition excellent in wear resistance, extreme pressure properties and low friction properties for mechanical friction sliding members.
The present invention provides a lubricant composition containing, as the major ingredient, the compound shown by the chemical formula [1], preferably a compound of triazine structure:
(R - X - ) m - D [I]
wherein, D is a heterocyclic residue of 5- to 7-membered cyclic structure positioned at the center of the molecule, or compound residue of cyclic structure with "m" radiating side chains; X is a single bond, group shown by NR1 (R1 is an alkyl group having a carbon number of 1 to 30 or hydrogen atom), oxygen atom, sulfur atom, carbonyl group, sulfonyl group, or a combination thereof forming a divalent coupling group; R is an alkyl, alkenyl, alkinyl, aryl or heterocyclic group; and "m" is an integer of 3 to 11.
本发明的目的是为机械摩擦滑动部件提供一种具有优异耐磨性、极压性能和低摩擦性能的实用润滑剂组合物。
本发明提供了一种润滑剂组合物,其主要成分含有
化学式 [1] 所示的化合物,最好是三嗪结构的化合物:
(R - X - ) m - D [I]
其中,D 是位于分子中心的 5 至 7 元环状结构的杂环残基,或具有 "m "放射侧链的环状结构的化合物残基;X 是单键、NR1 所示的基团(R1 是碳原子数为 1 至 30 的烷基或氢原子)、氧原子、
硫原子、羰基、磺酰基或它们的组合,形成二价偶联基团;R 是烷基、烯基、炔基、芳基或杂环基团;"m "是 3 至 11 的整数。
