一种天然酯绝缘油用高性能复合添加剂及其制备方法
摘要：
本发明公开了一种天然酯绝缘油用高性能复合添加剂及其制备方法，属于绝缘油添加剂技术领域，由基础油、抗氧化剂、降凝剂和金属钝化剂组成，所述抗氧化剂占添加剂重量的18%～25%，所述降凝剂占添加剂重量的13%～20%，所述金属钝化剂占添加剂重量的8%～10%。本发明抗氧化剂、金属钝化剂和降凝剂复配使用，有效提高天然酯绝缘油的抗氧化性能和低温特性，抑制金属腐蚀，而且添加剂之间产生的协同增效作用能够进一步提高添加剂效能，延长添加剂的使用寿命。
摘要（英）：

The invention discloses a high-performance composite additive for natural ester insulating oil and a preparation method thereof, belonging to the technical field of insulating oil additives. The high-performance composite additive consists of base oil, an antioxidant, a pour point depressant and a metal passivator, wherein the antioxidant accounts for 18-25% of the weight of the additive, the pourpoint depressant accounts for 13-20% of the weight of the additive, and the metal passivator accounts for 8-10% of the weight of the additive. The antioxidant, the metal passivator and the pour pointdepressant are compounded and used, so that the antioxidant performance and the low-temperature characteristic of the natural ester insulating oil are effectively improved, and metal corrosion is inhibited; and the synergistic effect generated between the additives can further improve the efficiency of the additives and prolong the service life of the additives.
