Description
技术领域
本发明涉及润滑脂制备技术领域,具体涉及一种重负荷高温抗水轧辊轴承润滑脂及其制备方法。
背景技术
轧机是钢铁生产过程中关系到钢材质量好坏的关键设备,轧机连续或往复地对钢坯进行高压轧制,其工况非常复杂,不但需承载极高的负荷,非常高的转速,而且由于受到钢坯的连续热辐射作用,轴承温度较高,且轧制过程中还有冷却水能够进入到轴承座中,因此,轧机的轧辊轴承对润滑脂的要求非常高,需要润滑脂承受重负荷、耐高温和抗水。
复合皂基润滑脂的出现,使高滴点皂基润滑脂进入润滑领域成为了可能。复合钙基脂具有良好的极压性、复合锂基脂具有良好的机械安定性、复合铝基脂具有优异的抗水性,这些复合皂基润滑脂都只在某一特定的指标方面具有优异的性能,而复合磺酸钙基润滑脂自问世起,就以其全面、优异的性能引起了国内外润滑脂行业的广泛关注。复合磺酸钙基脂由基础油、稠化剂和添加剂等组分组成,其主要特性取决于稠化剂。复合磺酸钙基脂的稠化剂不同于其它复合皂基脂。复合磺酸钙基脂的稠化剂是由具有触变性能的非牛顿体高碱性磺酸钙与脂肪酸皂、无机酸盐复合而成,非牛顿体高碱性磺酸钙则是由油溶性的牛顿体高碱性磺酸钙在转化剂作用下转化形成。牛顿体高碱值磺酸钙是烷基苯磺酸钙正盐和无定型碳酸钙颗粒组成的物质。由于复合磺酸钙基脂稠化剂的特殊构成,因此,复合磺酸钙基脂具有其它复合皂基脂的优良性能,即具有良好的机械安定性、胶体安定性、优良的抗水性、优异的极压性等性能,是一种具有广阔发展前景的多功能润滑脂。但是,目前的复合磺酸钙基润滑脂存在胶体稳定性差,长期储存容易析出基础油,且表面容易硬化的问题。
发明内容
本发明的目的在于提供一种重负荷高温抗水轧辊轴承润滑脂及其制备方法,从而满足轧辊轴承对润滑脂的苛刻要求。通过基础油、转化剂、复合稠化剂来改善复合磺酸钙基机械安定性尤其是减少复合磺酸钙基润滑脂在存储过程中稠度变化值,从而增加复合磺酸钙基润滑脂的胶体稳定性能。同时提升复合磺酸钙基润滑脂高温抗氧化性能、极压抗磨性能和防锈性能。
本发明解决其技术问题所采用的技术方案是:一种重负荷高温抗水轧辊轴承润滑脂,所述重负荷高温抗水轧辊轴承润滑脂由基础油、牛顿体高碱值磺酸钙、微粒碳酸钙、硼酸、转化剂、高纯水、氢氧化钙、氢氧化锂、二元酸、十二羟基硬脂酸、抗氧剂、抗磨剂组成,且各组分的比重如下:基础油40-50份、牛顿体高碱值磺酸钙20-35份、微粒碳酸钙0.001-0.01份、硼酸0.4-1份、转化剂3-5份、高纯水2-10份、氢氧化钙1-6份、氢氧化锂1-6份、二元酸1-8份、十二羟基硬脂酸1-8、抗氧剂0.1-2份、抗磨剂0.5-1.5份。

进一步,所述抗氧剂为芳胺类、烷基化二苯胺或二苯胺衍生物。
进一步,所述二元酸和十二羟基硬脂酸与氢氧化钙、氢氧化锂生成复合稠化剂,二元酸为癸二酸、邻苯二甲酸、己二酸和十二烷二酸中的至少一种。
一种重负荷高温抗水轧辊轴承润滑脂的制备方法,包括以下步骤:
S1:首先确定各组分的比例,然后再将牛顿体高碱值磺酸钙、80%的基础油和微粒碳酸钙在反应釜中混合、搅拌,加热升温至75-95℃,保持30-60min,在不停搅拌的条件下,加入转化剂和高纯水,保持60-90min,然后再将釜温控制在105-110℃,在该温度加热40-60min进行脱水,依次加入氢氧化钙乳液、氢氧化锂溶液、硼酸水溶液、十二羟基硬脂酸、二元酸,保持搅拌40-60min;

S3:接着降温至60℃以下,经均质机均化或三辊机研磨后制得高性能轧辊轴承润滑脂;
