Description
技术领域
本发明涉及一种防冻液，具体涉及一种煤矿液压支架专用的防冻液。
背景技术
液压支架是煤矿综合机械化采煤工作面最主要的技术装备之一，也是综采工作面装备中装备数量最多的设备。天气寒冷会使液压支架内部残留液体将会结冰膨胀，导致阀门、橡胶密封圈、压力表等液压系统元件损坏，造成巨大的经济损失。
现有的液压支架乳化液润滑性、金属防护性较好，但是不具有防冻功能，发动机防冻液有优异的防冻性能，但润滑性不能满足要求，稳定性不好，不符合液压支架技术要求。乙二醇为主的防冻液达不到液压支架的技术要求，而且乙二醇具有毒性，对人体和环境造成污染。
发明内容
本发明的目的是针对现有防冻液存在的不足，提供了一种液压支架专用防冻液，满足了防冻、润滑的要求，而且不会对人体和环境造成污染。
本发明的目的是通过以下技术手段实现的：
组成及质量百分含量为：丙三醇25%～45%，防霉剂0.5%～1%，防锈剂 10%～20%，润滑剂10%～15%，余量为水。
防霉剂选用十二烷基二甲基苄基氯化铵，防锈剂选用十二二酸，润滑剂选用蓖麻油酯化物，即蓖麻油进行酯化反应的产物。
制备的过程如下：
将适量水加入反应釜中，保持温度在40～42 ℃，加入上述原料，搅拌30分钟，加入余量水，搅拌20分钟。
与现有技术相比本发明具有以下明显的优点：1.环保，对人体和环境无害；2.防冻性、润滑性好，热稳定性好；3.降低生产成本。
具体实施方式
下面结合实施例对本发明做进一步说明。
实施一
按下列组成及质量百分含量配比液压支架防冻液，丙三醇25%，十二烷基二甲基苄基氯化铵0.5%，十二二酸10%，蓖麻油酯化物10%，本实施例使用蓖麻油与三羟甲基丙烷的酯化物,余量为水。
按照MT76-2011的标准对本发明的防冻液检测，结果如下表。
实施二
按下列组成及质量百分含量配比液压支架防冻液，丙三醇40%，十二烷基二甲基苄基氯化铵1%，十二二酸20%，蓖麻油酯化物20%，本实施例使用蓖麻油与三羟甲基丙烷的酯化物，余量为水。
按照MT76～2011的标准对本发明的防冻液检测，结果如下表。
以上所述，仅为本发明的一部分具体实施方式，本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。
Claims (1)
1.液压支架专用防冻液，其特征是，其组成及质量百分含量为：丙三醇 40%，十二烷基二甲基苄基氯化铵 1%，十二二酸 20%，蓖麻油酯化物 20%，余量为水；其中所述的蓖麻油酯化物为蓖麻油与三羟甲基丙烷的酯化物；
所述的液压支架专用防冻液的制备过程如下：将适量水加入反应釜中，保持温度在40～42 ℃，加入原料，搅拌30分钟，加入余量水，搅拌 20 分钟。
