Description
技术领域
本发明属于润滑脂技术领域,具体涉及一种耐高温低噪音聚脲基工业机器人用润滑脂。
背景技术
机器人在使用中会有杂音出现,这些是由于运动轴转动时铸件间的卡顿,摩擦产生的。而造成这一现象的原因是机器人使用时运动轴等部件会产生大量热量,从而使润滑脂所处环境温度过高,造成高温下润滑脂脂失去润滑效果。
因此,工业机器人必须选用耐高温型润滑脂,才能带来低噪音,减少摩擦的效果。
据了解,目前市场上用到的高温型润滑脂,主要有以下三类:
一、金属皂类润滑脂,如复合磺酸钙基脂,锂基脂,钠基脂等,但这类润滑脂因为有金属盐的加入,对金属表面有一定的腐蚀作用,其抗氧化能力不好,长时间使用,对设备会带来一定损失。
二、引入金属皂到聚脲润滑脂中制成的复合聚脲润滑脂,如用磺酸钙复合改良的聚脲润滑脂,虽提高了滴点,但是剪切安定性变差,锥入度变化大,机械安定性不好,无疑影响到润滑脂的使用性能。
三、膨润土润滑脂,膨润土润滑脂有很好的耐高温性能,但其长时间使用易变稀流失,且基础油难于进入摩擦表面,抗磨性能不足,会加大对工业设备磨损力度。
发明内容
本发明针对工业机器人使用中的这些问题,提供了一种耐高温低噪音聚脲基润滑脂,它高温稳定性好,极压抗磨,抗氧化能力强,且生产工艺简单,是一款非常适用工业机器人使用的润滑脂。
本发明提供一种耐高温低噪音聚脲基工业机器人用润滑脂,按质量百分数计,由以下原料制备而成:基础油65%---80%,稠化剂10%---15%,酚醛树脂2%---3%,极压抗磨剂1%--2%,抗氧剂2%---3%,防锈剂1%---2%。
进一步,所述基础油为矿物润滑油或合成润滑中的一种或两种。
进一步,所述稠化剂为异氰酸酯和有机胺原料制备得到。
进一步,所述异氰酸酯为单异氰酸酯、二异氰酸酯、三异氰酸酯或多异氰酸酯中的一种或多种。
进一步,所述有机胺为十八胺、十二胺、环己胺或对苯甲胺中的一种或几种。
进一步,所述稠化剂中各成份的质量比:二异氰酸酯5%---7% ,环己胺2%---3% ,十八胺3%--5%。
进一步,所述极压抗磨剂为硫化异丁烯、磷酸酯、硫化烯烃或环烷酸鉛中的一种或几种,所述防锈剂为石油磺酸钡、亚硝酸钠或十二烯基丁二酸中的一种或几种,所述抗氧剂为二苯胺、二异辛基二苯胺或硫化铵基甲酸盐中的一种或多种。
本发明还提供上述的一种耐高温低噪音聚脲基工业机器人用润滑脂的制备方法,包含以下步骤:
(一)将1/2基础油和二异氰酸酯混合搅拌,升温至70℃--85℃,恒温30---60分钟;
(二)将1/2基础油和环己胺混合搅拌,升温至70℃---85℃,恒温30---60分钟,恒温后加入十八胺,搅拌均匀;
(三)将步骤(一)和步骤(二)的产物合一起搅拌升温至90℃---110℃,恒温1---2小时,再升温至130℃---150℃,加入酚醛树脂,搅拌恒温15---30分钟;
(四)降温至80℃---100℃,加入各种添加剂,搅拌均匀,60℃---80℃时,脱气,出脂。
有益效果
(一)本申请相比其他同类型产品,最大的不同是加入了一定量的改性酚醛树脂,它具有优良的耐热性,耐水性,耐酸碱性,和耐磨性,对润滑脂的抗氧化性能,抗磨性能以及滴点的提高起到很大的帮助。
