Description

一种液压油组合物 技术领域
本发明涉及一种液压油组合物，更具体而言，涉及一种基于甘油酯的并且具有低温阻燃性能的液压油组合物。
背景技术
液压油是润滑油的主要产品之一，它的研制和生产是液压技术发展的重要组成部分，对提高液压设备的性能和延长液压元件的使用寿命具有重要的作用。现有液压油按产品组成可分为矿物油型、合成型和水合型三大类。
矿物油型和合成型液压油为非抗燃液压油，具有低温抗磨、良好的抗氧化及防腐性等，但其在环境中很难被生物降解，在使用过程中会因液压系统的泄漏造成严重的环境污染。含水型液压油为阻燃液压油，又分为含水型乳化液(油包水及水包油型)、水-乙二醇液压液和磷酸酯液压液，该类液压油受到使用温度等因素的制约，使用范围受到限制。
中国专利申请CN103343035A公开了一种液压油组合物，包括：基础油60-85重量份；粘度指数改性剂5-30重量份；油性剂1-10重量份；极压抗磨剂0.5-5重量份；抗氧剂0.1-0.5重量份；腐蚀抑制剂0.1-3重量份，其既能保证液压油系统所需的粘度、抗磨损、抗氧化和抗腐蚀性能，又具有极好的退火清净性。
中国专利申请CN101812355A公开了一种新型合成型抗燃液压油组合物，其特征在于：它是一种由低粘度酯类油为基础油，少量的合成烃成分作为增溶剂，以高粘度酯类油为增粘剂，再配以适当的功能添加剂所得的抗燃液压油组合物，该组合物具有较低的挥发性、优异的润滑性、高低温稳定性、更宽的使用温度范围、良好的抗燃性、可生物降解性和长使用寿命等优良性能。
中国专利CN101113383B公开了一种含纳米抗磨添加剂的酯类阻燃液压油，其原料的重量配比如下：合成酯类化合物基础油：90-95％，复合多功能添加剂：1.0-5.0％，纳米抗磨添加剂：1.0-5.0％；其极大地提高了产品的高温使用性能、长期润滑性能，可大大延长液压系统的使 用寿命和油品的换油期。
业界总是希望不断提高液压油产品的性能，例如在高低温条件下都具有较强的抗磨、抗氧化及防锈等性能和阻燃性能，具有良好的低温流动性等。
