Description

一种汽车制动液及其制备方法
技术领域
本发明涉及精细化工汽车化学品领域，具体是一种汽车制动液及其制备方法。
背景技术
汽车制动液是汽车液压式制动系统中用来传递制动能量的功能性液体，其性能及质量状况直接关系到车辆的行驶安全。自从20世纪30年代初汽车开始使用制动液以来，汽车制动液可以按照其生产原料的不同分为三种类型：蓖麻油-醇型、矿物油型和合成型制动液。蓖麻油-醇型、矿物油型制动液因其沸点低，凝固点高逐渐被淘汰，合成型制动液被广泛使用。
合成型制动液又分为硅油型、醇醚型和硼酸酯型。随着汽车工业的发展和人们对安全越来越高度的重视，ABS防抱死制动装置在制动系统中得到广泛的应用，必须研发具有高的干湿沸点和低的低温运动粘度的高级制动液，以更好地适应ABS防抱死刹车系统。此外，由于硼酸酯型制动液具备优异的高低温性能、高性价比以及与醇醚型制动液较好的相容性，特别适用一些高性能车辆和在极端温度环境下的应用，如大型工程机械车辆、赛车、南极考察、高温热带地区等。
国家对汽车制动液的质量有严格的要求(GB+12981-2003)，其主要涉及到制动液的高温抗气阻性、低温流动性、对橡胶的溶胀性、抗金属腐蚀性、抗氧化性、稳定性等。标准中DOT4要求ERBP不小于230℃，WERBP不小于155℃，-40℃时运动粘度不大于1800。目前，国内汽车配件市场中出售的汽车制动液大部分是不合格产品，其主要的问题是对制动系统腐蚀严重、对橡胶有溶胀性、质量蒸发损失不达标，从而导致汽车制动存在不安全隐患、维修频繁、维修费增加等；另外其高温抗气阻性和低温流动性不能满足要求，而受到气候条件及季节的限制。随着硼酸酯合成技术的不断完善，汽车制动液高温性能和低温性能得到了大的改进，但仍存在对制动系统的腐蚀、抗氧化性差不达标等问题。

作为本发明再进一步的方案：所述聚乙二醇单醚的化学式为HO(CH2CH2O)nCmH2m+1，式中n＝2～4，m＝1～4，CmH2m+1为直链或支链烷基。
作为本发明再进一步的方案：所述PH调节剂为丁基二乙醇胺。

2)经基础溶液降温至50-70℃，称取并加入硼酸、苯并三氮唑、二烷基二硫代氨基甲酸锌、抗氧剂264、三乙醇胺和硼砂，搅拌1-2h后，获得第一溶液；
3)将第一溶液冷却至室温，加入PH调节剂调节PH至7-9，获得第二溶液；
4)将第二溶液过滤，获得该汽车制动液。
与现有技术相比，本发明的有益效果是：1、本发明汽车制动液通过苯并三氮唑、二烷基二硫代氨基甲酸锌和抗氧剂264配合，能够明显的提高汽车制动液的抗氧化性能，在抗氧化性试验中，铸铁的质量变化为0.01-0.06mg/cm2，铝的质量变化为0.00-0.02mg/cm2，符合GB12981质量指标，且表现优异。2、本发明汽车制动液的高温抗气阻性、抗腐蚀性、高温稳定性、化学稳定性以及蒸发损失等均达到了HZY5的标准。

表1抗氧化性试验结果
从表1可以看出，本发明汽车制动液的抗氧化性试验中，铸铁的质量变化为0.01-0.06mg/cm2，铝的质量变化为0.00-0.02mg/cm2，符合GB12981质量指标，且表现优异。
将实施例3与对比例1-3的试验结果进行对比，对比例1中不含苯并三氮唑、二烷基二硫代氨基甲酸锌和抗氧剂264，其抗氧化性达不到GB12981质量指标，对比例2中仅含有抗氧剂264，对比例3中仅含有苯并三氮唑和二烷基二硫代氨基甲酸锌，对比例2和对比例3的抗氧化性虽然达到了GB12981质量指标，但表现一般，实施例3中同时含苯并三氮唑、二烷基二硫代氨基甲酸锌和抗氧剂264，其抗氧化性达到了GB12981质量指标，且表现优异。因此可以看出，苯并三氮唑、二烷基二硫代氨基甲酸锌和抗氧剂264配合，能够明显的提高汽车制动液的抗氧化性能。
抽取本发明实施例3的汽车制动液的样品，按照GB12981进行其他性能检测，检测结果如表2所示。
表2GB12981性能检测结果
本发明汽车制动液的样品达到HZY5标准，性能优异。
上面对本发明的较佳实施方式作了详细说明，但是本发明并不限于上述实施方式，在本领域的普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化。
