Description

液压支架用乳化液
技术领域
本发明涉及一种液压支架用乳化油及其制备方法，属于乳化油技术领域。
背景技术
液压支架用乳化油适用于煤矿液压支架与外注式单体液压支柱等***的动力传递介质，能有效的保护液压***，延长其使用寿命。传统的液压支架用乳化油是用矿物油为原料生产出来的，但是石油是不可再生资源,并且废弃的液压油不易降解会污染环境。目前普遍采用乳化性能和冷却性能相对较好、环保安全的非离子乳化剂，添加各种功能性添加剂合成乳化油，但是仍然存在易腐败变质，乳液不稳定会出现析油析皂现象加剧对传动***的磨损，影响设备的使用寿命等诸多问题。
发明内容
本发明要解决的技术问题是提供一种具有优良的极压润滑、抗磨、冷却、防锈、清洗性，且乳液稳定性好，不易腐败变质的液压支架用乳化液，以及该液压支架用乳化液的制备方法。
本发明为解决上述技术问题提出的一种技术方案是：一种液压支架用乳化液，其特征在于,包括以下质量百分比的组分：水溶性蓖麻油40%～50%，二壬基萘磺酸钡20%～30%，复配添加剂15%～20%，非离子表面活性剂0.5%～2%，环烷酸锌1%～2%，十二烯基丁二酸1%～3%，硼砂1%～3%，二烷基二硫代磷酸锌0.2%～1%，水4%～8%；所述复配添加剂是由35～45质量份的硼酸、35～45质量份的三乙醇胺、3～8质量份的氢氧化钠反应而成。
所述水溶性蓖麻油是蓖麻油和乙二醇在催化剂的作用下缩合而成。
所述蓖麻油与乙二醇的质量比为1:10～1:8。
所述催化剂是有机酸催化剂。
所述有机酸催化剂是甲基苯磺酸。
所述非离子表面活性剂是OP-10和Span-80中的一种或两种。
本发明为解决上述技术问题提出的另一种技术方案是：一种上述的液压支架用乳化液的制备方法，将水加入反应釜中，然后加入硼酸和氢氧化钠，升温至90℃～95℃，保温搅拌20分钟～30分钟，再加入三乙醇胺，保温搅拌2小时～3小时，待液体透明后加入非离子表面活性剂，搅拌20分钟～30分钟，温度控制在70℃～75℃加入水溶性蓖麻油、二壬基萘磺酸钡、环烷酸锌、十二烯基丁二酸、硼砂和二烷基二硫代磷酸锌，继续搅拌20分钟～30分钟，混合均匀后即可得到成品。
本发明具有积极的效果：本发明的液压支架用乳化液由改性植物油、防锈剂、复配添加剂、非离子表面活性剂、抗磨剂、防腐剂等混合而成。复配添加剂采用硼酸、三乙醇胺、氢氧化钠反应而得硼酸与氢氧化钠反应生成硼酸钠，硼酸与三乙醇胺反应生成三乙醇胺硼酸酯，具有极好的乳化、润滑和防锈效果，非离子表面活性剂降低乳化液对pH值的依赖性，使得乳化效率高，并且保持较低的表面张力，具有很好的清洗性。二壬基萘磺酸钡代替石油磺酸钡和石油磺酸钠，配以环烷酸锌、十二烯基丁二酸、硼砂等防锈剂，可以有效提升防锈性。硼砂、二烷基二硫代磷酸锌具有抗氧化的作用，同时二烷基二硫代磷酸锌可以作为抗磨剂使用。本发明的液压支架用乳化液采用改性植物油替代机械油，具有优良的极压润滑、抗磨、冷却、防锈、清洗等功能，不含有苯甲酸盐，亚硝酸盐等有害物质，所以对环境无污染、不腐蚀、不发臭、无毒无味，对人体、皮肤、眼睛无刺激无损害等。与500mg/l以下硬度的水质配成5%的乳化液可用于井下液压支架与外注式单体液压支柱的液压液，或作液压机械***的传动介质。
