Description

一种环保无氯型钛合金切削油及其制备方法
技术领域
本发明涉及一种环保无氯型钛合金切削油及其制备方法。
背景技术
钛合金材料具有质量轻，强度大，耐高温和耐腐蚀等特点，上至飞机、航天器，下至船舶、深潜器、石油开采、化学工业等行业得到了广泛的应用。随着钛冶炼技术和加工工艺的改进和完善，钛及钛合金产品品种也在进一步扩大，质量控制水平也进一步提升，其应用领域也在扩大。钛是目前医疗器械、人工关节、骨科植入物、心脏起搏器等的理想材质。在眼镜、珠宝、手机、电脑等民用休闲产品，钛合金也是未来的发展方向。
钛合金的是典型的难加工材质，主要有以下特点：
1、强度高，硬度大，要求加工设备的功率大；
2、切屑与前刀面接触面积小，刀尖应力大；
3、弹性模量小，刚性差，切削加工时，回弹大，容易造成剧烈摩擦、粘附、粘结磨损和工件变形。
4、高温下活性高，容易反应生成硬化层，增加钛合金表面硬度，极易造成崩刃现象，加剧刀具磨损。
5、导热系数小，切削温度高，刀具很容易产生粘结磨损。
钛合金加工过程中刀具寿命的关键因素，如何降低切削区域温度，增加散热速度，延长刀具使用寿命，提高加工效率，进一步降低钛合金产品的制造成本，是推动钛合金广泛应用的关键。
同时，社会环保意识越来越强，节能减排、解决环境污染是趋势，欧盟相关法规中已禁止使用短链、中链氯化石蜡，长链氯化石蜡的使用问题也是备受争议。氯化石蜡稳定性差，再加上钛合金切削过程中温度高，极易分解，产生氯气、氯化氢等有毒有害气体，严重危害健康，长期接触刺激呼吸系统、刺激皮肤，严重者可导致肝肾功能损害。分解产生的氯气、氯化氢等还会导致机床、模具生锈，设备故障，设备维修保养成本大幅增加。
因此，环保无氯型钛合金切削油是发展的趋势，也是本发明要解决的关键技术问题。
目前国内现有的钛合金切削油，基本仍然采用氯化石蜡，高活性硫化极压剂、含磷极压剂、动物油、植物油、合成酯等添加剂，虽然可获得极高的润滑性，但此类物质带来的腐蚀性强，分解产物腐蚀工件、腐蚀机台不环保。
现有的无氯切削油为了获得高的油膜强度，采用高黏度基础油，切削油的整体散热性差，使用过程中，切削油油温高，机台、工件烫手，人工操作不方便。
