Description
技术领域
本发明属于精细化工生产技术领域,具体涉及一种可生物降解的润滑油。
背景技术
润滑油基础油主要分矿物基础油、合成基础油以及生物基础油三大类。矿物基础油应用广泛,用量很大(约95%以上),但有些应用场合则必须使用合成基础油和生物油基础油调配的产品,因而使这两种基础油得到迅速发展。
我国市场最流行润滑油油品大多是以石油为基础油的润滑油,它们难以降解,几乎长期留在环境中。每年全球消耗润滑油为3600~4000万吨,其中1000万吨左右的润滑油由于泄漏、飞溅、油气蒸发、包装用品的残留、不当地抛弃等原因直接进入人类居住的生态环境,严重污染土壤和水资源,破坏生态环境。人们对润滑油的污染问题也很关注。但到目前为止,绝大多数使用的润滑油,还是石油为基础油的润滑油。
植物油基的润滑油是一种环境友好的润滑油,如豆油、玉米油、菜籽油、棉籽油、蓖麻油等,其中最早进入市场的是德国用菜籽油(含油量35~40)合成的润滑油。但菜籽油凝点较高,低温时容易凝固,酯化后低温性能不理想。菜籽油的氧化稳定性较差,在高温时容易形成油泥和沉淀物。因此,能否以植物油为基础制备出合适的润滑油,使其能够有效的生物降解,是值得研究的课题。
发明内容
发明目的:针对现有技术中的不足,本发明提供了一种可生物降解的润滑油。
技术方案:本发明所述的一种可生物降解的润滑油,包括植物基合成油12~18份、粘度调节剂2~6份、防腐剂2~5份、杀菌剂2~5份、消泡剂2~5份和水50~60份。
所述的植物基合成油的成分及组成为:油酸2~10份、亚油酸2~4份、蓖麻油80~90份、硬脂酸0.5~2份、二羟硬脂酸0.5~2份。
所述的粘度调节剂为亚乙基双硬脂酸酰胺。所述的消泡剂为聚氧乙烯聚氧丙烯季戊四醇醚。所述的防腐剂为双乙酸钠。所述的杀菌剂为甲基托布津。
所述植物基合成油通过以下方法得到:将油酸2~10份、亚油酸2~4份、蓖麻油80~90份混合搅拌,得到油状混合物,并保持搅拌状态;将硬脂酸0.5~2份、二羟硬脂酸0.5~2份混合加热,加热至60~65℃后,逐渐加入油装混合物中,持续搅拌10~15分钟。
上述过程中,优选的原料配比为:将油酸8份、亚油酸34份、蓖麻油88份、硬脂酸1份、二羟硬脂酸1份。
所述的润滑油通过以下方法得到:将植物基合成油加热至40~45℃后加入防腐剂、杀菌剂、消泡剂和水,在35~40rps的转速下搅拌10~20min;最后加入粘度调节剂,在30~35rps的转速下搅拌20~30min,即得到。
