为了实现上述目的，本发明的第一方面的技术方案提供了一种高效无灰液压油复合剂组合物，包括以下重量份组分：抗氧剂25～35份、抗磨剂50～60份、防锈剂4～15份、基础油3～8份。

优选地，所述烷基二苯胺抗氧剂可为丁基辛基二苯胺或双辛基二苯胺中的任意一种。
在该技术方案中，配制高效无灰液压油复合剂组合物的原料较为普遍，不含金属元素，灰分少。本发明提出的高效无灰液压油复合剂组合物能溶于各种矿物油，对各种矿物油感受性良好，同时，对各种矿物油抗氧化能力、抗磨能力均有大幅提升，本发明提出的高效无灰液压油复合剂组合物如添加到矿物油基础油中，可将磨斑直径降至0.43mm，抗氧化旋转氧弹时间可达到1000分钟以上。
本发明的第二方面的技术方案还提出了一种高效无灰液压油复合剂组合物的制备方法，包括：称取配方量的各物料，反应釜开启搅拌并依次加入基础油、抗磨剂、抗氧剂、防锈剂，升温至50℃～60℃；常压下搅拌1.5h～2h，检验合格后冷却至室温过滤装桶。
在该技术方案中，高效无灰液压油复合剂组合物的制备方法简单，工艺简单，可操作性强，有利于大范围推广使用。
需要说明的是，搅拌的转速可以为80r/min；产物以0.8％加剂量与150N基础油常温搅拌均匀，混合物呈透明状，无浑浊即认为检验合格。
