顺丁烯二酸二丁酯混合甲基纤维素的叉车轴承用润滑油
技术领域:
本发明涉及叉车轴承用润滑油领域,具体涉及一种顺丁烯二酸二丁酯混合甲基纤维素的叉车轴承用润滑油。
背景技术:
润滑油是涂在机器轴承表面的油状液体,按其来源分动物油、植物油、石油润滑油和合成润滑油四大类,其具有减少摩擦,避免发热、防止机器磨损等作用。
然而传统的叉车轴承的引擎润滑油在使用不久之后容易变黑,因为引擎润滑油在持续清理碳粒子,当空气中的氧与引擎油起作用后,将产生浓稠的黑炭泥粒子包覆在引擎零件上,当引擎的运转速度和温度越高,分解的速率越快,氧化分解不仅会对引擎造成损坏,而且会阻塞油管,导致油品无法传送至引擎,增加了设备的维护成本,降低了引擎的使用寿命。
发明内容:
本发明所要解决的技术问题在于克服现有技术的缺陷,提供一种顺丁烯二酸二丁酯混合甲基纤维素的叉车轴承用润滑油。
本发明所要解决的技术问题采用以下技术方案来实现。
一种顺丁烯二酸二丁酯与甲基纤维素混合叉车轴承专用润滑油,由以下重量份的原料组成:
大豆150-200份、改性胺与聚酰胺混合体10-15份、丙烯酸丁酯20-25份;甲基纤维素60-65份、对苯二酚10-13份、丙烯酸5-6份、氰乙酸乙酯5-6份、固体甲醛5-6份、醋酸乙烯6-9份、磷酸三甲酚酯8-11份、顺丁烯二酸二丁酯30-40份、环烷基基础油40-50份、抗磨损剂2-5份、防腐防锈剂5-10份、清洁因子2-5份、抗氧化剂5-15份、金属减活化剂1-3份和粘度调节剂8-12份、吡啶4-4.6份、过硫酸钠1.5-2.2份。
进一步地:所述的抗磨损剂为硫化脂。
进一步地:所述的防腐防锈剂为金属酚盐。
进一步地:所述的抗氧化剂为2,3-二叔丁基对甲酚。
进一步地:所述的金属减活化剂为硫化物。
进一步地:所述的粘度调节剂为烷基苯乙烯。
一种顺丁烯二酸二丁酯混合甲基纤维素的叉车轴承用润滑油的制备方法,包括以下步骤:
步骤1:取大豆,分离大豆皮,待用,从大豆中分离蛋白8%-20%、尿素15%-17%、多聚磷酸钠1%-10%,将尿素分散在水中,混合制成尿素溶液,
步骤2:将丙烯酸丁酯与甲基纤维素混合,放入蒸馏瓶内,同时将改性胺与聚酰胺混合体与环烷基基础油混合,待完全混合后,加入顺丁烯二酸二丁酯,加入蒸馏内混合,得到基础油;
步骤3:将基础油、防腐防锈剂及抗氧化剂,混合,进行高温低压蒸馏,温度460-480℃、压强0.03-0.06MPa,快速分离轻质油和重质油;
步骤4:将重质油,加入蛋白,在常温下搅拌1-2小时,再加入多聚磷酸钠,继续搅拌2-3小时,然后进行沉淀分离,分离后,取上1/3层油;
步骤5:将大豆皮磨碎,装入提取器中,加入重质油和尿素溶液,在固液比例为12:1,温度为70-80℃的条件下提取6小时,然后抽滤,对滤液进行真空浓缩,回收溶剂;
步骤6:将步骤4和步骤5混合,采用分级萃取,萃取压力为28-35MPa,温度42-48℃,萃取时间为1.5-2小时,然后进行二级分离,第一级分离压力为8-10MPa,温度为53-57℃,第二季为3-5MPa,温度为30-40℃;
步骤7:依次加入对苯二酚、丙烯酸、醋酸乙烯、磷酸三甲酚酯,加热搅拌,加热温度为190℃,时长10分钟、冷却至70℃,加入氰乙酸乙酯、固体甲醛;
步骤8:将步骤6、步骤7与抗磨损剂、清洁因子、金属减活化剂、粘度调节剂按原料比例混合,过滤,即可。
本发明的有益效果是:在控制基础油成本的同时能够保证较好的粘度指数和高抗磨性能;通过助剂的配合添加,能有效去除包覆在引擎零件上浓稠的黑碳泥粒子,延长引擎的使用寿命,降低设备的维护成本,为叉车轴承引擎提供洁净的磨损防护模式,同时在此基础上,利用大豆和甲基纤维素添加能改善润滑油的导热性,润滑油抗乳化性、抗泡性非常好,但是其空气释放性却不是很理想。
