Description
技术领域
本发明属于化工产品领域，特别涉及一种铜及铜合金拉丝工艺用乳化油及其制备工艺。
背景技术
拉丝液是铜及铜合金拉丝加工中必用的润滑介质，为拉丝工艺的顺利进行提供良好的润滑和冷却，同时对拉制出的新生面提供腐蚀保护，进而确保最终产品的质量合格。目前，铜拉丝工艺中所用的拉丝液根据油含量或乳液粒径大小的不同分为三大类：乳化型、微乳型、以及全合成型。乳化型拉丝液由于其良好的润滑性和调制工艺简单等优点，在拉丝应用中仍占据主导地位。微乳型拉丝液由于调制工艺严苛、油基稳定性差等位居第二，而全合成型拉丝液由于润滑性和防腐性能较差，无法满足一些较为苛刻的工况，在实际使用中较少应用。
乳化型拉丝液最重要的两项性能是润滑极压性和防锈防腐性，现有技术中大多采用多元醇酯、聚醚、植物油、含P剂、含Cl剂、含B剂、高碱值磺酸盐等作为润滑极压剂。多元醇酯类润滑剂虽然润滑性能优良，但此类添加剂性能单一，需要耗用大量的乳化剂才能使之乳化；聚醚类润滑剂润滑效果一般；植物油虽然润滑性优异，但使用一段时间后易产生铜皂，进而堵塞模孔；含P剂加量过大会产生细菌，废液也难以处理；很多含Cl剂和含B剂均对环境和人体有害，一些硼酸盐类添加剂和高碱值磺酸盐对金属退火后的清净性会产生的影响。本发明采用自乳化酯和特定范围分子量的聚酯和亚甲基双(二丁基二硫代氨基甲酸酯)以一定比例复配作为润滑极压剂，其具有优异的润滑性，能有效地降低拉丝过程中的摩擦磨损，而且极压效果极佳，甚至超过了含Cl剂和含P剂的效果，完全能满足对工况要求较为苛刻，或硬度较高的合金铜的润滑需求；同时，该复合润滑剂具有良好的自乳化性和生物降解性，能有效减少乳化剂的用量，对环境和人体无害。
现有技术中大多采用单一的苯丙三氮唑，或是苯丙三氮唑与多元羧酸复合作为防锈防腐剂，上述防腐剂往往加量较大，且对于产品表面质量要求较高的工艺来说，其防腐性远不能满足需求。本发明以含氮衍生物与十二烯基丁二酸复配，极大地降低了防腐剂的加量，同时引入正十二烷基胺与C14-C16异构醇，在协同增强防腐性的同时，有效地提高了体系的稳定性与产品表面光亮度。此外，助剂高分子量丁二酰亚胺的引入，可有效地分散生产过程中的铜皂，其与杀菌剂共同作用，极大地延长了拉丝液的使用寿命。
发明内容
本发明的目的在于克服上述现有技术中的不足之处，提供了一种润滑和防腐性能优异的铜及铜合金拉丝用乳化油及其制备方法。由其配置的工作液润滑性和清洗性俱佳，拉制出的铜或铜合金线材表面光亮洁净。同时，该油品具有良好的抗菌消泡性，后期维护少，使用寿命长等特点。

所述的润滑剂为自乳化酯，优选短链的醇与二酸反应而成的自乳化酯，如二甲基己二酸酯、二甲基琥珀酸酯、二甲基戊二酸中的一种或几种混合物。
所述的杀菌剂为吗啉或苯骈异噻唑啉酮(BIT)。
所述的基础油为40℃运动粘度小于40mm2/s且苯胺点低于100℃的矿物油。

本发明与现有技术相比，具有优异的润滑极压性和防锈防腐性，可满足工况较为苛刻的铜及铜合金拉丝工艺的润滑和防腐需求，拉制出的产品表面光亮洁净无擦伤。同时油品具有很好的稳定性与抗菌性，使用寿命较长。体系中正十二烷基胺与防锈防腐剂复配作用，既提高了防腐性，又增强了稳定性。该乳化油无需添加任何中间体，生产制备工艺简单，且性价比较高。
