윤활제 조성물

본 발명은 구동 소자들의 표면상으로 적용하기 위한 윤활제 조성물에 관한 것으로, 상기 윤활제 조성물은 기유(base oil) 및 실세스퀴옥산(silsesquioxane)을 함유한다. 상기 조성물은, 회색 얼룩(gray staining), 폴스 브리넬링(false brinelling) 및 화이트 에칭 크랙스(white etching cracks)와 같은 구동 소자들의 재료 내 피로도(fatigue phenomena)를 예방하거나, 감소시키거나, 또는 방지하기 위해 적합하다. A lubricant composition for application onto a surface of drive elements includes: a base oil; and a silasesquioxane. In an embodiment, the silasesquioxane has the chemical formula [RSiO3/2]n with: n=6, 8, 10, 12; where R independently of one another=alkyl (C1-C20), cycloalkyl (C3-C20), alkenyl (C2-C20), cycloalkenyl (C5-C20), alkynyl (C2-C20), cycloalkynyl (C5-C20), aryl (C6-C18) or heteroaryl group, oxy, hydroxy, alkoxy (C4-C10), oxirane polymer (degree of polymerization with 4 to 20 repeat units), carboxy, silyl, alkylsilyl, alkoxysilyl, siloxy, alkylsiloxy, alkoxysiloxy, silylalkyl, alkoxysilylalkyl, alkylsilylalkyl, halogen, epoxy (C2-C20), ester, aryl ether, fluoroalkyl, blocked isocyanate, acrylate, methacrylate, mercapto, nitrile, amine, and/or phosphine group, each substituted or unsubstituted.
