Description
技术领域
本发明涉及牵引传动变速器用润滑油组合物。
背景技术
近年来，牵引传动变速器(T-CVT)等汽车用变速器具有要求动力传输的大容量化和小型化的动向的同时，又有要求用于其中的油脂类的省燃耗性或延长无换油距离的倾向。因此，汽车用变速器中使用的润滑油组合物被要求具有更高级别的氧化稳定性或极压性(耐烧结性)。
关于上述问题，专利文献1中提出了含有特定受阻酚化合物构成的抗氧化剂的润滑油组合物。此外，专利文献2中，有人提出含有酸性磷酸酯的润滑油组合物。
现有技术文献
专利文献
专利文献1：日本专利特开平6-293892号公报
专利文献2：日本专利特开2010-202680号公报
发明内容
专利文献1的润滑油组合物通过受阻酚化合物使润滑油组合物获得了良好的氧化稳定性，但对于耐烧结性没有研究。
专利文献2的润滑油组合物通过酸性磷酸酯使润滑油组合物获得了良好的耐摩耗性，但对于耐烧结性以及氧化稳定性也没有研究。此外，在润滑油组合物中添加酸性磷酸酯时，为了抑制酸度上升所造成的腐蚀，要求在润滑油组合物中添加碱以取得平衡。但是，专利文献2中公开的将碱(一元胺化合物)添加到润滑油组合物中时，存在酸性磷酸酯与该胺发生反应而沉淀的情况。此外，专利文献2的润滑油组合物是工作机械用油，对于汽车用变速器用没有任何记载。
进一步，牵引传动变速器用的润滑油组合物为了适当地传达动力，故要求较高的牵引系数。但是，专利文献1及2的润滑油组合物中，对于牵引系数与其他性能的平衡完全没有研究。
如上，如今还没有提出满足提高氧化稳定性、保持耐烧结性、防止碱的添加所造成的沉淀的产生、抑制牵引系数降低的牵引传动变速器用润滑油组合物。
本发明基于以上情况，以提供一种通过残留碱值而提高氧化稳定性的同时，保持耐烧结性，进一步防止因碱的添加而引起的沉淀的产生，同时能抑制牵引系数降低的牵引传动变速器用润滑油组合物为目的。
为了解决上述课题，本发明提供以下的牵引传动变速器用润滑油组合物。
1.一种混合(A)基础油、(B)磷酸酯系化合物、(C)抗氧化剂及(D)下述通式(I)所示的胺及/或该胺构成的氧化胺而成的牵引传动变速器用润滑油组合物。
[化1]
通式(I)中R1及R2各自独立地表示碳原子数1～26的直链状、支链状或环状烷基、碳原子数1～26的直链状、支链状或环状烯基、(R4-O)m-H或(R5-O)n1-(R6-O)n2-H，相互之间可以相同或不同。R4～R6各自独立地表示碳原子数2～3的亚烷基，m、n1及n2各自独立地表示2～25的数。
R3表示取代或无取代的碳原子数1～26的直链状、支链状或环状烷基，或取代或无取代的碳原子数1～26的直链状、支链状或环状烯基。

实施例
接着，通过实施例进一步详细说明本发明，但本发明不限于此。另，实施例中，润滑油组合物的评价及测定如下进行。结果见表1及2。
＜润滑油组合物的评价方法及测定方法＞
(1)碱值
基于JISK2501，通过盐酸法测定润滑油组合物(新油)的碱值。
(2)耐烧结性
在基于ASTMD3233(A法)的法莱克斯试验(转速：290rpm、油温100℃)中，测定试验片产生烧结时的负荷(N)。负荷越大表示耐烧结性能越优异。另，负荷达13340N也没有产生烧结的，记为“＞13340”。
(3)残留碱值量
对按照CECL-48-A-00[B]，在150℃、240小时的条件下进行了氧化稳定性试验的润滑油组合物，基于JISK2501通过盐酸法测定其碱值。
(4)外观
目测刚刚混合后的润滑油组合物(新油)的外观。无外观变化的为“〇”、产生白浊的为“△”、产生沉淀的为“×”。
(5)牵引系数
100℃的牵引系数的测定使用双圆筒摩擦试验机进行。即，使相接触的大小相同的圆筒(直径40mm、厚度20mm，被驱动侧是曲率半径20mm的滚筒型、驱动侧是无凸起的扁平型)中的一方速度固定、另一方的转速连续变化，通过砝码对两圆筒的接触部位施加147.1N的负荷，测定两圆筒间产生的切向力、即牵引力，求得牵引系数。该圆筒进行过铬钼钢SCM420的镜面精加工，平均圆周速度6.8m/s、最大Hertz接触压是1.24GPa。此外，牵引系数的测定在滑移率5％的条件下进行。
(6)μ降低率
基于上述获得的牵引系数，算出各实施例及比较例的牵引系数相对于比较例1的牵引系数的降低率。
〔实施例1～18及比较例1～15〕

[表1]
[表2]
从表1及表2可知以下事实。实施例的润滑油组合物在高温环境下长时间使用后碱值也能充分残留。其意味着即使是在严酷的条件下使用，碱也能长时间存在，氧化稳定性良好。此外，实施例的润滑油组合物在负荷13340N下也没有产生烧结，能保持耐烧结性，通过碱的添加也无沉淀产生。此外，实施例的润滑油组合物相对于作为参照的比较例1的牵引系数降低小，可以抑制牵引系数降低。
另一方面，比较例1～7、9～10及12～15的润滑油组合物在高温环境下长时间使用后，没有能残留充分的碱值。其意味着在严酷的条件下使用时，碱量不充分，无法满足氧化稳定性。此外，比较例7及8中由于使用伯胺或仲胺而产生了沉淀。此外，比较例9～11中由于使用金属系清净分散剂而损害了B成分磷酸酯系化合物保持耐烧结性的效果。
产业上的利用可能性
根据本发明，可以提供一种通过残留碱值而提高氧化稳定性的同时，保持耐烧结性，进一步防止因碱的添加而引起的沉淀的产生，同时能抑制牵引系数降低的润滑油组合物。因此，可作为牵引传动变速器(T-CVT)的润滑油组合物有效地利用。
