Description

一种曲轴用淬火油
技术领域
本发明涉及热处理技术领域，具体涉及一种曲轴用淬火油。
背景技术
化学热处理是将将金属或合金工件置于一定温度的活性介质中保温，使一种或几种元素渗入它的表层，以改变其化学成分、组织和性能的热处理工艺。化学热处理利用化学反应、有时兼用物理方法改变钢件表层化学成分及组织结构，以便得到比均质材料更好的技术经济效益的金属热处理工艺。由于机械零件的失效和破坏大多数都萌发在表面层，特别在可能引起磨损、疲劳、金属腐蚀、氧化等条件下工作的零件，表面层的性能尤为重要。
经过化学热处理的钢铁零件，需要经过淬火冷却，即在高温红热状态下，奥氏体组织快速浸入具有合适的冷却速度的淬火介质(油)中，才能实现零件达到需要的各项综合机械性能，从奥氏体组织转变成马氏体，并且零件没有开裂以及保持很小的变形。
淬火油应无毒、无味、易处理、对环境无污染，并使淬火后的工件表面光亮。现有淬火油的缺点：淬火时，油的温度会瞬时升高，如果油的闪点和燃点较低，可能发生着火现象；油品中的过量水分会影响零件的热处理质量，造成零件软点、淬裂或变形，也可能造成油品飞溅，发生事故；蒸汽膜阶段时间持续较长，会导致零件淬火冷却后：冷却不均匀，零件各部位软硬不均，淬火变形较大；且淬火后零件达不到要求的各项机械性能；淬火油有效寿命短。国内外目前没有专门的曲轴淬火专用淬火油。
发明内容
本发明所要解决的技术问题在于提供一种品相好，运动粘度低，抗老化、抗氧化性能优越，闪点高，导热性好的曲轴用淬火油。
本发明所要解决的技术问题采用以下技术方案来实现：

所述改性抗氧剂由下列重量份的原料制成：
卡波姆0.2-0.3份、2,6-二硝基苯甲酸0.2-0.3份、硫化烷基酚钙0.01-0.05份、丙烯酸甘油酯0.01-0.05份、二烷基二硫代磷酸锌0.1-0.2份、荷荷巴油2-5份、2，6-三级丁基-4-甲基苯酚1-2份、硫代二丙酸双酯1-2份、2，2-二苯基-1-三硝基苯肼0.1-0.2份、N,N-二甲基苯胺0.1-0.2份、丙烯酸异冰片酯0.1-0.2份；
所述改性抗氧剂的制备方法是：
将卡波姆、2,6-二硝基苯甲酸、荷荷巴油、2，6-三级丁基-4-甲基苯酚加入压力容器内加压至3-5MPa，然后在1h内加压至常压，打开容器再加入硫化烷基酚钙、丙烯酸甘油酯、二烷基二硫代磷酸锌、硫代二丙酸双酯、丙烯酸异冰片酯，加热至50-60℃，边加热边搅拌均匀，保持温度50-60℃10分钟后加入2，2-二苯基-1-三硝基苯肼、N,N-二甲基苯胺，然后利用在1000-1200转/分钟的搅拌机下拌匀即可。
一种曲轴用淬火油的制备方法，包括如下步骤：
(1)将基础油加入反应釜，然后放入5℃冷库保藏30min，然后加热至60-75℃，再加入三元乙丙橡胶、52％氯化石蜡、磺酸盐石油磺酸钡，混合均匀，备用；

(3)将步骤(2)所得物料加热至85℃，并保温10min，然后加入改性抗氧剂，混合均匀，再经过过滤即得该产品。
本发明的有益效果是：本发明淬火油品相好，运动粘度低，抗老化、抗氧化性能优越，闪点高，淬火过程中不会起火，导热性好，淬火过程中油品温度均匀，充分保证淬火工件的质量；特别适合于曲轴淬火用，能完全消除曲轴内部热应力，使得其金相组织分部均匀，大大提高曲轴硬度和耐磨性，保证曲轴长期使用不开裂。
