Description

一种新型润滑脂及其制备方法
（一）技术领域
本发明涉及一种润滑脂，特别涉及一种新型润滑脂及其制备方法。
（二）背景技术
目前，市场上的润滑脂产品，以锂基润滑脂和钙基润滑脂为主。而随着国民经济的发展，机械化生产代替人工生产成为制造加工服务行业的必然趋势，随之大量重负荷中转速机械设备出现。传统的钙基润滑脂因为滴点太低而无法满足这些机械设备的润滑需求，而锂基润滑脂的滴点又太高，用在此类设备上造成了资源浪费。
（三）发明内容
本发明为了弥补现有技术的不足，提供了一种性能优良、生产成本低的新型润滑脂及其制备方法。
本发明是通过如下技术方案实现的：
一种新型润滑脂，其特征为，由以下重量份数的原料经混合、皂化、脱水、冷却、剪切、过滤制成：羟基硬脂酸13%、环烷基基础油80%、氢氧化钙3%、氢氧化钠2%、氢氧化锂1%、松香酸0.4%、硅油0.2%、抗氧剂0.2%，增粘剂0.2%。
本发明以羟基硬脂酸、环烷基基础油、氢氧化钙、氢氧化锂为主要原料，同时添加氢氧化钠，提高产品的粘附能力，加入松香酸，提高了皂化能力，缩短了生产时间，提高了生产效率，另外硅油的加入延长了润滑脂的使用寿命，二苯胺作为抗氧剂使用，乙烯丙烯共聚物作为增粘剂使用。
本发明的更优技术方案为：
所述抗氧剂为二苯胺，增粘剂为乙烯丙烯共聚物，增强产品的表现性能。
本发明所述的新型润滑脂的制备方法，包括如下步骤：
（1）将羟基硬脂酸和占总量1/3的环烷基基础油加入制脂釜中，升温待羟基硬脂酸熔化后启动搅拌，温度升至50-60℃后，加入氢氧化钙、氢氧化钠、氢氧化锂、松香酸和硅油，然后升温至105-110℃进行皂化反应2-4h；
（2）皂化完成后，继续搅拌升温脱水，温度达到150-160℃时，加入占总量1/3的环烷基基础油，继续升温至180℃，加入抗氧剂；
（3）继续升温至210-220℃，制脂釜内物料呈真溶液状态；
（4）将制脂釜内的物料通过急冷混合器与剩余的环烷基基础油混合，送入调和釜内，同时启动搅拌和夹套冷却水，将物料用泵循环冷却；
（5）待物料温度降至150-170℃，加入增粘剂，将物料通过孔板剪切器剪切1-2h，再经均化、脱气、过滤处理，得到产品。
本发明克服了钙基润滑脂滴点过低的缺陷，融入了钙基润滑脂的优良防水性、钠基润滑脂的高粘附性和锂基润滑脂的耐高温性，并提高了造化能力，缩短了生产时间，节约了人力物力，同时还能提高润滑脂的使用寿命。
（四）附图说明
下面结合附图对本发明作进一步的说明。
图1为本发明的工艺流程示意图。
（五）具体实施方式
实施例：
原料：羟基硬脂酸13%、环烷基基础油80%、氢氧化钙3%、氢氧化钠2%、氢氧化锂1%、松香酸0.4%、硅油0.2%、二苯胺0.2%，乙烯丙烯共聚物0.2%。
制备方法：
（1）将羟基硬脂酸、占总量1/3的基础油加入制脂釜中，升温待脂肪酸熔化后，启动搅拌；温度升至50-60℃，按比例加入计量的氢氧化钙、氢氧化钠、氢氧化锂、松香酸和硅油，升温105-110℃进行皂化反应2-4h；
（2）皂化完成后，继续搅拌升温脱水，温度达150-160℃时加入占总量1/3的基础油；温度升至180℃时加入计量的二苯胺；
（3）继续升温至最高炼制温度210-220℃，使釜内物料呈真溶液状态；
（4）将釜内物料通过急冷混合器与剩余基础油混合后，送入调和釜内，同时启动搅拌和夹套冷却水，将物料用泵打循环，进行冷却；
（5）待物料温度降至150-170℃，加入乙烯丙烯共聚物，将物料通过孔板剪切器进行剪切1-2h后，经均化、脱气、过滤处理；
（6）成品检测合格后进行包装。
将得到的产品与3号钙基润滑脂、3号锂基润滑脂进行滴点检测对比，结果如下：
