Description

一种起重机械用液压油及其制备方法
技术领域
本发明属于液压油技术领域，具体涉及一种起重机械用液压油及其制备方法。
背景技术
机械种类很多，其中，例如挖掘机、装载机、起重机、搅拌运输车等，这些机械设备一般长年在自然环境恶劣的野外作业，都需要通过液压传递***进行必要的工作。液压油是液压技术的一个重要组成部分，在液压***中它能起到能量传递、***润滑、防腐、防锈、冷却等作用。随着液压***技术的不断发展，精密元件的应用越来越广泛，如精密过滤器等，为确保精密仪器的顺利工作，因而液压***用油的质量要求也逐渐提高。要求液压油应该具有良好的粘温性、抗磨性、水解安定性，以及相关材料的适应性、过滤性，特别是热稳定性和氧化安定性要好，以确保液压油在使用过程中有很好的清洁度，以满足日益更新的液压***用油要求。
抗磨液压油可以分为有灰型和无锌型。有灰型抗磨液压油具有很好的抗磨性，能满足叶片泵的使用要求。但当用于柱赛泵时，有灰型抗磨液压油会对柱塞泵的铜部件造成腐蚀，从而导致柱塞脚磨损、斜盘破裂。此外，由于有灰型的热稳定性差，在高压液***操作失灵。无锌抗磨液压油在水解安定性、破乳化性，过滤性、热稳定性和氧化安定性方面优于含锌抗磨液压油。
随着液压机械的发展和大范围的使用，以及人类对环境恶劣地区的开发，液压***将面临更多的来自工作环境的考验，因此液压***对液压油的要求越来越高，现用液压油并不能完全满足液压机械的需求。
公开号为CN105820860A，公开了一种节能工程机械液压油及其制备方法，由下述重量份的原料组成：磷酸三甲酚酯0.2-0.9份、抗磨剂0.8-1.2份、苯***十八胺盐4-6份、油酸乙二醇酯2-4份、氢化苯乙烯异戊二烯共聚物75-85份、单烯基丁二酰亚胺1.5-2.5份、2，5-二叔丁基对苯二酚1.5-2.5份、4，4'-二辛基二苯胺2.5-3.5份、聚甲基丙烯酸酯4-8份、二甲基硅油0.02-0.04份、基础油850-950份。公开号为CN104845712A，公开了一种高性能抗磨液压油及其制备方法，该液压油包括以下组分：基础油、粘度调节剂、极压抗磨剂、抗氧化剂、金属减活剂、润滑剂、抗泡剂，其中基础油包括以下组分：32N三类加氢基础油、32NS三类加氢基础油、邻苯二甲酸二辛酯、聚α-烯烃合成油。以上现有技术具有粘度指数较低、粘温性能差、氧化安定性差的缺点，并且原材料过多且价格并不便宜，增加了制备成本，使其不能推广使用。
综上所述，因此需要更好的液压油，来改善现有技术的不足，从而推动该行业的发展。
