Description
技术领域
本发明涉及一种冷却剂,特别是一种主轴油冷却液及其制备方法。
背景技术
近年来,科技发展日新月异,工业加工领域也在快速发展。在机械加工过程中,会产生大量的热量,如果降温不及时、长时间的保持高温状态,会对设备造成很大的损坏。因此,在机械加工过程中加入冷却剂是十分有必要的。
目前,在机械加工过程中的一个发展趋势是使用水溶性切削液逐步替代油溶性切削液,然而使用的主轴油冷却液还是油溶性冷却液。在机械加工过程中,主轴油冷却液非常溶液泄露到切削液中。如果主轴油冷却液使用油溶性冷却液,而切削液却使用水溶性切削液,当主轴油冷却液泄露到水溶性切削液中时,就会形成难以去除的浮油,进而造成切削液腐败发臭、降低使用寿命,增加加工厂的生产成本。同时,传统的油溶性冷却液的主要成分是矿物油,比热容较低、冷却效果较差;水的沸点较低,加工温度较高时容易气化。在转速5000r/min以上时,主轴和轴承的润滑冷却问题非常突出。
为解决这一问题,本发明提供了一中水溶性的主轴油冷却液,不仅可以与水溶性切削液互溶,还可以提高主轴冷却液的冷却性能。
