摘要
为了满足飞机等航空器在外场环境下的防护要求,以聚α烯烃油(PAO)为基础油,选用硬脂酸铝为稠化剂,采用适当的炼制工艺制成基础脂;在一定条件下加入合适的增黏剂,研制一种飞机防护润滑脂,并对其进行综合性能评价。评价结果表明,该润滑脂具有良好的黏附性、防锈性、抗水性和低温性,质量指标完全符合国家军用标准GJB 2095—1994的要求。所研制润滑脂的抗水性和黏附性与现用3号舰用润滑脂相当,防锈性和低温性明显优于3号舰用润滑脂。
In order to meet the requirements of protecting aircraft parts in various external field en-vironments, a type of lubricating grease for aircraft protection was developed using polyolefin synthetic oil （PAO） as base oil and aluminum stearate as thickener to prepare basic grease, and then adding tacki-fier under certain conditions. The performance of this prepared grease was evaluated comprehensively and the results show that this grease possesses excellent adhesion, rust protection, water resistance and low temperature performance, which can well meet the requirements of national military standard GJB 2095-1994. Comparing with 3^# ship grease used as an aircraft protecting grease presently, their water resistance and adhesion properties are similar, however, the rust protection property and low tempera-ture performance of this prepared aircraft protection grease are much better.
