    • PURPOSE: A grease composition using synthetic base oil is provided to obtain thermal stability and to have excellent shear stability and mobility due to a high dropping point, good affinity with the base oil, and a short length of a fiber structure. CONSTITUTION: A grease composition includes base oil which is used for lubrication and a thickener deciding the property of the grease. The base oil is comprised of 70 ~ 85 weight% of synthetic base oil in which polyalphaolefin of high viscosity having dynamic viscosity of 350 ~ 600 cSt at 40°C and polyalphaolefin of low viscosity having dynamic viscosity of 80 ~ 150 cSt at 40°C are mixed. The thickener is comprised of 6 ~ 16 weight% of a complex soap thickener and 8 ~ 15 weight% of an additive.
    • 目的:提供使用合成基础油的润滑脂组合物,以获得热稳定性,并且由于滴点高,与基油的亲和性好,纤维结构短而具有优异的剪切稳定性和流动性。 构成:润滑脂组合物包括用于润滑的基础油和增稠剂,以决定润滑脂的性质。 基础油由70〜85重量%的合成基础油组成,其中40℃下动态粘度为350〜600cSt的高粘度聚α-烯烃和40℃动态粘度为80〜150cSt的低粘度聚α-烯烃 混合 增稠剂由6〜16重量%的复合皂增稠剂和8〜15重量%的添加剂组成。
