一种含有纳米银抗菌的半合成切削液及其制备方法
技术领域
本发明涉及一种半合成切削液，具体涉及一种含有纳米银抗菌的半合成切削液及其制备方法。
背景技术
半合成金属切削液，又称微乳金属切削液，即按一定的比例用水稀释，乳化微粒直径小于1μm，应用于金属切削等加工行业上，同时兼有乳化液良好的润滑性和合成液良好的清洗性特点，又具有合适的极压性能，是非常有发展前景的一类切削液；半合成金属切削液的主要成分为润滑基础油(矿物油)、水、乳化剂、防锈剂、极压抗磨剂、消泡剂、防霉杀菌剂等。乳化剂、矿物油、极压抗磨剂的含量方面都比乳化金属切削液要低。水基半合成金属切削液的前景是非常美好的，不仅在金属切削液所需求的性能方面表现优异，而且环保、易稀释，成本也较之其他种类的金属切削液要低。
史仁宗在《半合成切削液的制备研究》中利用矿物油、极压搁滑剂制备了一种水基半合成切削液，但是其抗磨性、稳定性还有待提高。
