Description

一种抗硬水的液压支架用浓缩液及制备方法
技术领域
本发明属于液压支架用油技术领域，更具体地涉及抗硬水的液压支架用浓缩液及制备方法。
背景技术
液压支架是煤炭行业采煤工作面用于支撑顶板的重要机械设备，其与采煤机配套使用，不仅实现了采煤综合机械化，提高了采煤和运输设备的效能，而且最大限度的保障了煤矿工人的生命安全，液压支架用环保型浓缩液是液压支架系统的“血液”，液压支架的升降、移动和过截保护等都需要应用液压支架用环保型浓缩液。
长期以来，我国一直使用乳化油，由于乳化油具有润滑效果好和防锈效果明显的优势，一直备受人们的喜爱，但是由于乳化油是不可再生的石油资源，价格受国际石油产品的影响很大，石油资源越来越少，价格只能逐步上升，还有污染环境的问题，特别是在使用过程中还有一定的析油析皂现象，造成滤网阻塞，需要经常清洗滤网，而这些析出的油皂与煤尘结合形成很难清洗的粘稠物，会给工作现场的使用造成诸多不良影响，对电液控制系统则会堵塞过滤组件等问题。
专利号为201610278017 .2的国家发明专利公开了一种液压支架用环保型浓缩液及其制备方法，采用了非矿物油作为原料生产液压支架用环保型浓缩液，很好的解决了上述问题，但是该浓缩液的抗硬水能力较差。
发明内容
为解决上述问题，克服现有技术的不足，本发明提供了一种采用非矿物油作为原料的液压支架用浓缩液具有优秀的防锈功能和抗硬水功能，够有效的解决防锈效果和抗硬水效果较差的问题。
本发明解决上述技术问题的具体技术方案为：抗硬水的液压支架用浓缩液，其特征在于，由下述组分按重量百分比组成：土耳其红油：10.0%～20.0%、三乙醇胺：5.0%～8.0%、油酸：5.0%～8.0%、NP-10：3.0%～5.5%、尿素：5.0%～8.0%、T-60：1.0%～1.5%、苯甲酸钠：10%～15%、EDTA-2Na：2.0%～3.5%、氢氧化钠：1.0%～2.0%、苯骈三氮唑：0.1%～0.3%、其余为水；
所述的抗硬水的液压支架用浓缩液是由如下方法制得的：
步骤一.取油酸和三乙醇胺在氢氧化钠溶液的催化作用下进行皂化反应，反应温度70℃-90℃，反应时间2.5h，反应结束PH在8.0-8.5，皂化结束后待用；
步骤二.取所需量三分之一的水，将EDTA完全溶于水中，将尿素、苯甲酸钠和苯骈三氮唑依次加入水中至完全溶解；
步骤三.将步骤一中皂化反应物缓慢加入步骤二中，搅拌均匀至澄清，然后再加入配方量的土耳其红油，搅拌均匀，然后再加入配方量的NP-10和T-60；
步骤四.加入剩余水，搅拌30分钟。
进一步地，所述的水为自来水。
进一步地，各组分均为工业级。
本发明的有益效果是：本发明在保证全面防锈效果的同时，具有较为优良的抗硬水能力，使液压支架使用寿命增加，大大降低了维护费用，同时配置时需要自来水就可以满足生产需要，降低了生产要求，降低了成本。
