A glycol- and/or glycerin-based universal aircraft fluid (i.e., usable as any of Type I, II, III, or IV fluids), and having good resistance to degradation of viscosity and other critical properties caused by exposure to heat and/or shear, is disclosed. The fluid may optionally be prepared as a concentrate, and thereafter significantly diluted in the field for diverse uses. The improved performance is achieved by neutralizing a latex of a hydrophobe-containing, polymeric thickener with a base, preferably an alkali metal hydroxide, and preferably in combination with a weak base such as a salt of a weak acid, and a surfactant which associates with the thickener.
本发明公开了一种以乙二醇和/或甘油为基础的通用飞机润滑液(即可用作 I、II、III 或 IV 型润滑液中的任何一种),该润滑液具有良好的抗粘度降解能力以及其他因暴露于热量和/或剪切力而导致的关键性能。该流体可选择制备成浓缩物,然后在现场进行大量稀释,以用于各种用途。性能的改善是通过用碱(最好是碱金属氢氧化物,最好是与弱碱(如弱酸的盐)和与增稠剂结合的表面活性剂)中和含憎水剂的聚合物增稠剂的胶乳来实现的。
