本发明属于液压液组合物，尤其涉及一种水基难燃液压液组合物及其制备方法。
背景技术
液压油液是液压传动系统中动力传递的载体。针对在漏液情况下有着火风险的液压系统，实际应用包括炉门，压铸机，锻压机械和采矿设备等，普通的矿物油型液压油难以很好地满足实际使用要求。从安全性角度出发，对于上述液压系统，要求其使用的液压油液必须具有优异的抗燃性能。含水溶性聚合物类难燃液压液(HFC类难燃液压液)是目前广泛使用的一种难燃液压液，其价格低廉、防锈抗磨性能优良，是一种具有优异性价比的难燃液压液。
传统的HFC类难燃液压液主要由去离子水、低分子量二元醇(如乙二醇和二乙二醇)、高分子量水溶性聚合物以及各种功能性添加剂调制而成。随着环保法规的日益严苛，使用后的传统型HFC类难燃液压液被归类为危险品，不能直接排放至河流湖泊中。由于HFC类难燃液压液可完全溶解于水中，因此采用传统的含油污水处理工艺难以有效实现无害化处理。此外，废旧的传统型HFC类难燃液压液具有较高的COD值，因此该废液需要作为特殊废物予以针对性处理，从而会增加处置程序和成本。同时，传统型HFC类难燃液压液所使用的低分子量二元醇(如乙二醇和二乙二醇)具有较强的毒性，吸入人体内会对呼吸系统以及中枢神经系统等造成较大的危害。
