Description

新型触变性润滑脂及其制备方法
技术领域
本发明涉及新型触变性润滑脂及其制备方法。
背景技术
轴承在运转的时候，润滑脂在轴承里面受到很强的剪切力，在这种力的作用下，润滑脂会发生改变，到了一定程度润滑脂就是去了保护轴承的作用，润滑脂的使用寿命决定于润滑脂的能力大小。尤其是在集中供脂系统中，集中供脂系统是利用泵的很强的压力将润滑脂通过管线输送到轴承里面，这就需要润滑脂具有较强的泵送性和较大的稠度。但是现有技术中，集中供脂系统中使用的润滑脂一种是泵送性达到要求，但是稠度小；一种是稠度大，但是泵送行达不到要求。
发明内容
本发明的目的是提供新型触变性润滑脂及其制备方法，本发明制备的润滑脂具有较强的触变性。
为了解决上述技术问题，本发明提供的新型触变性润滑脂及其制备方法是这样实现的：
一种新型触变性润滑脂，由以下百分比的原料制成：基础油60%-72%，稠化剂15%-25%，添加剂3%-5%和填料膨润土10%-20%；所述稠化剂为两种或两种以上脂肪酸铝盐的复合皂；所述添加剂为防腐剂、抗氧化剂的一种或几种。
可选的，所述脂肪酸铝盐由硬脂酸和异丙醇铝制成或由苯甲酸和三异丙氧基铝制成。
可选的，所述防腐剂为：硫化烯烃棉籽油T405A。
可选的，所述抗氧化剂为：二苯胺。
新型触变性润滑脂的制备方法，将基础油加入皂化釜内，搅拌加热到80度时，加入第一种脂肪酸，不断搅拌；继续加温到130度时，加入第一种铝醇，不断搅拌；继续加温到135度时恒温45分钟；恒温后，加入第二种脂肪酸，不断搅拌；继续升温到185度时，加入第二种铝醇，搅拌均匀，加温在185-200度之间，保持1.5小时；然后循环剪切，后加入机械油；温度下降到100度时，加入填料，搅拌均匀；温度下降到75-77度时，加入添加剂，然后剪切脱气包装。
可选的，所述第一种脂肪酸为硬脂肪酸，所述第一种铝醇为异丙醇铝。
可选的，所述第二种脂肪酸为苯甲酸，第二种铝醇为三异丙氧基铝。
本发明使用国标基础油和复合铝皂生产的润滑脂，国标油具有很好的抗腐蚀性能和抗极压性能、良好的抗乳化性能，保证润滑脂具有低温扭矩润滑性能和长寿命。复合铝皂和膨润土的混合皂，其特点是具有触变性，是润滑脂具有长寿命的特点，适合集中供脂。膨润土使润滑脂具有很高的耐温性能和较低的钢网分油性能。因此本发明相对于现有技术，润滑脂具备较强的触变性，提高润滑脂的使用寿命，且生产成本相对于现有技术中使用高质量的基础油生产具有触变性的润滑脂，本发明降低具有触变性润滑脂的生产成本。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
触变性是指润滑脂经过剪切以后润滑脂的锥入度会发生改变，有的会变稠有的会变稀，一般情况下会变稀，当剪切力消失后润滑脂的锥入度又回到了原来的状况。也就是说具有触变性的润滑脂在剪切力的作用下，剪切前后具有可逆性。
