Description

一种以环氧化植物油为基础油的环保冷镦油及其制备方法
技术领域
本发明属于金属工件的冷成型加工领域，具体涉及一种新型冷镦油及其制备方法。
背景技术
随着冶金、汽车、轮船、航天等科技的发展，需要成型加工的金属零部件越来越多、越来越大，要求的精度和负荷也越来越高，对冷镦油的润滑、极压、清洗、防锈等性能要求也越来越高，而且对环保的要求也越来越严格。传统的冷镦油以矿物油为基础油，虽然在性价比上有少许优势，但其属于不可再生资源的衍生物，而且生物降解性差，长期排放累积以后会对生态环境造成严重污染。生产厂家在采用产品时，不仅要考虑成本，还要考虑其综合性能以及后续的处理排放问题。在资源紧缺和环境保护日益重要的今天，选用一种可再生而且对环境危害很小的产品显得尤为重要。
发明内容
本发明的目的是提供一种润滑极压性好、适合加工温度范围大、具有良好抗磨性能并可以生物降解的新型冷镦油；同时，本发明也提供该新型冷镦油的配制方法。
本发明所采用的技术方案如下：
本发明以环氧化植物油为基础油的环保冷镦油，其特点在于：所述冷镦油的各组分按重量份的构成为：
其中，所述基础油为环氧化植物油。
优选的，所述基础油为环氧化大豆油和环氧化菜籽油中的至少一种，所述基础油在40℃时运动粘度均为30～40mm2/s。
所述润滑剂为妥尔油、氯化羟基脂肪酸酯和三羟甲基丙烷脂肪酸酯中的至少一种；
所述防锈剂为石油磺酸钠和苯并三氮唑的混合物；
所述极压剂为含氯极压剂氯化石蜡S52、含硫极压剂RC2540、硫化猪油以及油性磷酸酯的混合物；
所述防腐剂为苯并异噻唑啉酮和3-碘-2-丙炔基丁基氨基甲酸酯的混合物；
所述抗氧化剂为BHT和TBHQ中的至少一种；
所述降凝剂为聚甲基丙烯酸酯类降凝剂。
上述环保冷镦油的制备方法，包括如下步骤：
首先，按配比将环氧化植物油加入到调和釜中，再按配比加入润滑剂和极压剂，升温到50-60℃，搅拌30～40分钟；
然后按配比加入防锈剂和防腐剂，继续搅拌30-60分钟；
最后按配比加入抗氧化剂和降凝剂，搅拌20-30分钟，即获得环保冷镦油。
与现有技术相比，本发明的有益效果体现在：
同传统的矿物油相比，环氧化植物油具有较高的粘度指数、更好的润滑极压和抗磨性能、低挥发性、高闪点以及良好的生物降解性能等特点，本发明采用环氧化植物油作为基础油，可替代传统的不可再生的矿物油，不仅避免了不可再生资源的消耗，而且极大地减轻了对环境的污染；采用含氯极压剂氯化石蜡S52、含硫极压剂RC4801、硫化猪油和油性磷酸酯作为极压剂，适合加工温度范围大的机加工；以苯并异噻唑啉酮和3-碘-2-丙炔基丁基氨基甲酸酯作为防腐剂，提高了产品的使用寿命，解决了目前三嗪类杀菌剂杀菌谱窄的缺点；以聚甲基丙烯酸酯类产品作为降凝剂，很大的降低了产品的倾点，使产品在较冷的条件下也能保持良好的流动性。
本发明的产品适合于各种机加工，如碳钢冷镦、温镦螺母、高强度螺栓套筒、空心及半空心铆钉的成型加工，也可用于铆钉的成型加工；同时，本发明的配制方法简易，对设备要求也不高。
