Abstract
本发明公开了一种采棉机摘锭装置用润滑脂。包括如下重量份数的组分：基础油80～94份、稠化剂5～10份、极压抗磨剂0.2～5份、防锈剂0.1～0.5份。本发明的采棉机摘锭润滑脂有超高滴点和优良的附着能力，高温抗剪切力，优良的低温流变性能，优良的极压抗磨性能；一方面确保润滑脂在较高环境温度下具有超强的锥入度保持能力和附着力，确保更长的使用寿命，节约成本；另一方面确保‑10℃甚至更低的低温环境下具有良好的泵送性能，确保采棉机摘锭头的正常运行；另外本发明的润滑脂吸附到棉花上不污染棉花，后续加工环境友好。
Description
技术领域
本发明属于润滑脂技术领域，具体涉及一种大马力采棉机摘锭装置润滑脂。
背景技术
随着社会发展和技术进步，棉花采摘已从过去的低效率大量人工采摘逐步过渡到采棉机的机械采摘，大大提高了采摘效率，解放了大量的人力，缩短了采摘期，降低了采摘成本。采棉机摘锭装置为采棉机重要工作单元，摘锭头的齿轮传动装置（座管）需要一种根据设备运行工况和环境状况使用的齿轮传动润滑脂。由于结构设计特点，采棉机上部有一个储脂箱，用于专门贮存备用的润滑脂。当需要补充润滑脂时，启动润滑脂驱动泵，将润滑脂泵送到摘锭齿轮装置系统对高速运转的齿轮进行润滑。一方面采棉机的采摘摘锭装置运行原理要求采棉机用润滑脂必须具备优异的附着性能、抗磨性能，并不会由于摩擦导致温度升高而降低润滑脂的附着力，尽可能地确保润滑脂润滑到每个摘锭头的传中齿轮。另一方面由于采棉季节昼夜温差较大，以及采棉期持续时间较长，前期采棉环境温度高达35℃左右，后期采棉环境温度可能低至-10℃左右。因此要求采棉机润滑脂必须具备优异的低温流变性能，以适应高、低温采棉环境，确保采棉机不会因为环境温度变化而无法正常运行，影响彩棉进度。另外现有市售采棉机润滑脂均采用锂基皂作为稠化剂，一方面锂金属较为稀有，价格昂贵，大量采用会大量吸附到棉花上面，对后续加工带来不必要的困难；另一方面润滑脂会大量地滴漏到土地上，对土地造成污染，日积月累，造成土地不可持续种植使用。
发明内容
本发明的目的在于提供一种采棉机摘锭装置用润滑脂。
一种采棉机摘锭装置用润滑脂，包括如下重量份数的组分：基础油80～94份、稠化剂5～10份、极压抗磨剂0.2～5份、防锈剂0.1～0.5份；所述稠化剂为下述式I所示的化合物和碱金属皂按照质量比1：1的混合物：
所述基础油为环烷基基础油、多元醇酯基础油、合成烃基础油中的一种或两种的混合物。
所述基础油在40℃的运动粘度为20mm2/s～30mm2/s，凝固点在-25℃以下、闪点在160℃以上。
所述碱金属皂是指将单独的羧酸或酯用锂、钠、钾、钡等碱金属的氢氧化物进行皂化得到的皂。
优选的，所述碱金属皂为锂皂或者钡皂。
作为碱金属皂的具体例，可以举出使水解油脂除去了丙三醇的粗制脂肪酸、硬脂酸等单羧酸或 12-羟基硬脂酸等单羟基羧酸、壬二酸、癸二酸等二元酸、对苯二甲酸、水杨酸、苯甲酸等芳香族羧酸与例如氢氧化锂等锂化合物反应得到的物质。上述物质中，优选使用硬脂酸或12-羟基硬脂酸的锂系皂。
所述极压抗磨剂为氯化石蜡和磷酸三丁酯按照质量比3：1的混合物。
所述防锈剂为十二烯基丁二酸、十二烯基丁二酸酯、十七烯基咪唑啉烯基丁二酸盐、十二烯基丁二酸胺盐中的一种或几种的混合。
所述采棉机摘锭装置用润滑脂的制备方法，按照如下步骤进行：将10-90wt%的基础油加入到调和釜中，搅拌并加热基础油到70-90℃，逐步加入稠化剂，继续搅拌至稠化剂全部分散到基础油中，加入余下的基础油、极压抗磨剂和防锈剂，继续搅拌至分散均匀。
本发明的有益效果：本发明的采棉机摘锭润滑脂选用超低凝固点的基础油，并加入稠化剂和极压抗磨剂，使得润滑脂均有超高滴点和优良的附着能力，高温抗剪切力，优良的低温流变性能，优良的极压抗磨性能。一方面确保润滑脂在较高环境温度下具有超强的锥入度保持能力和附着力，确保更长的使用寿命，节约成本。另一方面确保-10℃甚至更低的低温环境下具有良好的泵送性能，确保采棉机摘锭头的正常运行。另外本发明的润滑脂吸附到棉花上不污染棉花，后续加工环境友好。
