Description

一种电动车链条链轮保养用润滑脂
技术领域：
本发明涉及电动车保养技术领域，具体涉及一种电动车链条链轮保养用润滑脂。
背景技术：
电动车，即电力驱动车，是一种环保型出行工具。以电池作为能量来源，通过控制器、电机等部件，将电能转化为机械能运动，以控制电流大小改变速度的车辆。链条和链轮是电动车的关键驱动部件，为了保证电动车的正常使用以及延长其使用寿命，需要对其进行定期保养。通常的保养措施是利用润滑脂来减小链条和链轮之间的磨擦阻力，降低链条和链轮的结构磨损。目前，普遍使用的润滑脂都存在散热效果差的问题，且易吸附灰尘而使润滑脂黏度增大，从而增大磨擦阻力，起不到润滑效果。
发明内容：
本发明所要解决的技术问题在于提供一种散热效果好、润滑效果佳且润滑周期长的电动车链条链轮保养用润滑脂。
本发明所要解决的技术问题采用以下的技术方案来实现：
一种电动车链条链轮保养用润滑脂，由如下重量份数的原料制成：
环氧改性硅油15-20份、聚乙酸乙烯酯5-10份、聚氧化乙烯5-10份、甲基丙烯酸缩水甘油酯3-6份、氯化聚乙烯橡胶2-4份、C5加氢石油树脂2-4份、米糠蜡2-4份、聚四氟乙烯超细粉2-4份、氢化棕榈油1-2份、石油焦微粉1-2份、纳米胶粉1-2份、双环戊二烯树脂0.5-1份、硫酸化蓖麻油0.5-1份、纳米硼酸锌0.5-1份、钼酸铋0.1-0.2份。
其制备方法包括如下步骤：
(1)向聚乙酸乙烯酯中加入甲基丙烯酸缩水甘油酯和C5加氢石油树脂，并以5℃/min的升温速度升温至110-115℃保温混合30min，再加入环氧改性硅油、纳米胶粉和钼酸铋，继续升温至130-135℃保温混合15min，然后自然冷却至室温，即得物料I；
(2)向聚氧化乙烯中加入氯化聚乙烯橡胶和聚四氟乙烯超细粉，并以5℃/min的升温速度升温至125-130℃保温混合30min，再加入氢化棕榈油、石油焦微粉和双环戊二烯树脂，继续在125-130℃保温混合10min，然后自然冷却至室温，即得物料II；
(3)向物料I中加入物料II、米糠蜡、硫酸化蓖麻油和纳米硼酸锌，充分混合后于0-5℃环境中静置2h，再以10℃/min的升温速度升温至120-130℃保温混合15min，最后以5℃/min的降温速度降温至室温，即得润滑脂。
所述米糠蜡使用前经过预处理，其处理方法为：向米糠蜡中加入交联聚维酮和氢化松香甘油酯，充分混合后利用微波处理器微波处理5min，转入10-15℃环境中静置30min后继续微波处理3min，再加入六羟甲基三聚氰胺六甲醚和2-咪唑烷酮，混合均匀后继续微波处理5min，最后将所得混合物转入0-5℃环境中静置1h，即完成米糠蜡的预处理。
所述米糠蜡、交联聚维酮、氢化松香甘油酯、六羟甲基三聚氰胺六甲醚和2-咪唑烷酮的质量用量比为15-20:1-2:0.5-1:0.5-1:0.1-0.3。
所述微波处理器的额定微波频率为2450MHz、输出功率为700W。
米糠蜡经过上述预处理后，不仅能显著增强其与环氧改性硅油的共混相容性，还能提高其耐热性和柔滑性。
所述纳米胶粉由如下重量份数的原料制成：松香改性酚醛树脂5-10份、气相白炭黑3-5份、活性白土3-5份、阴离子聚丙烯酰胺3-5份、石棉粉2-3份、三羟甲基丙烷三丙烯酸酯2-3份、海泡石纤维1-2份、环氧大豆油1-2份、玻纤粉0.5-1份，其制备方法为：向松香改性酚醛树脂中加入活性白土和环氧大豆油，充分混合，以5℃/min的升温速度升温至125-130℃保温混合15min，再加入气相白炭黑、阴离子聚丙烯酰胺和三羟甲基丙烷三丙烯酸酯，继续在125-130℃下保温混合15min，然后以5℃/min的降温速度降温至55-60℃密封保温静置30min，并加入石棉粉、海泡石纤维和玻纤粉，再以10℃/min的升温速度升温至115-125℃保温混合10min，最后趁热将所得混合物送入纳米研磨机中，经研磨制得纳米胶粉。
上述所制纳米胶粉渗透性极强，能均匀渗透到润滑脂制备原料中，起到增强润滑脂润滑性、耐磨性和耐候性的作用。
本发明的有益效果是：本发明所制电动车链条链轮保养用润滑脂的颜色透明、粘度适中，将其涂抹于链条链轮上能起到优异的润滑作用，散热效果好，能显著降低链条与链轮之间的磨擦力，减轻两者因摩擦力而导致的结构损耗；同时润滑周期长，不易吸附灰尘；并且耐高低温性和耐候性好，不会出现因成分变质而导致润滑脂粘度变大、润滑效果消失甚至增加磨擦的问题。
