Description

一种铝壳拉伸油组合物
技术领域
本发明涉及金属加工油领域，尤其涉及一种铝壳拉伸油组合物。
背景技术
汽车动力电池是新能源汽车核心能量源，为整车提供驱动电能，其主要通过壳体包络构成电池主体。电池壳体作为电池模块的承载体，对电池模块的安全工作和防护起着关键作用。
汽车动力电池包采用铝合金材料，其具有易加工成型、耐高温耐腐蚀性、良好的传热性和导电性特点。铝壳可一次拉伸成型，相对于不锈钢可以省去盒底焊接工艺，在进行焊接时不会出现因为金属元素烧损而导致质量下降的问题。
随着新能源汽车的高速发展，动力电池铝壳的市场越来越大，铝壳拉伸过程中铝合金材料的变形量大，拉伸过程对拉伸油的润滑要求极高。采用现有的拉伸油在拉伸过程中铝合金材料和模具摩擦会产生大量的铝粉，铝壳表面会残留拉伸油和铝粉，残留的拉伸油和铝粉难以清洗，会影响铝壳成品质量，从而导致产品合格率降低。因此现有的铝壳拉伸油性能有待改良。
发明内容
本发明的主要目的在于提供一种铝壳拉伸油组合物，旨在解决现有铝壳拉伸油残留在铝壳表面难以清洗的问题。
为了实现上述目的，本发明提供一种铝壳拉伸油组合物，按重量百分比该组合物由以下组分组成：

优选地，所述铝壳拉伸油组合物，其中，所述油性剂为大豆油、棕榈油酸酯、三羟甲基丙烷油酸酯、季戊四醇油酸酯中的至少一种。
本发明的油性剂由于酯官能团极性大，在铝合金表面的吸附能力强，所形成的油膜强度高，润滑性好。
优选地，所述铝壳拉伸油组合物，其中，所述极压润滑剂为硫化肉豆蔻烯酸甲酯。
优选地，所述铝壳拉伸油组合物，所述硫化肉豆蔻烯酸甲酯由肉豆蔻烯酸甲酯与硫在非均催化剂的催化条件下反应制得，所述硫化肉豆蔻烯酸甲酯有极压润滑性好、低气味、易清洗的特点，化学反应方程式如下：
Figure SMS_2
其中，所述硫化肉豆蔻烯酸甲酯由以下步骤制备而成：
a)将121g肉豆蔻烯酸甲酯和1.5g非均相催化剂加入到三口烧瓶中，在氮气氛围下加热至120℃，在搅拌速度为400—500rad/min的条件下缓慢加入13.4g硫，搅拌条件下加热使得温度上升至200℃，在 200℃下反应6h停止加热；
b)在三口烧瓶内温度降至80-90℃后，将三口烧瓶内反应得到的产物进行过滤，过滤得橙黄色油状液体即为硫化肉豆蔻烯酸甲酯，有效硫含量9.8-10.0％。
优选地，所述铝壳拉伸油组合物，其中，所述分散剂为聚异丁烯丁二酰亚胺、聚异丁烯丁二酸季戊四醇酯、硫磷聚异丁烯钡盐中的至少一种。

由于铝合金拉伸成铝壳过程中变形量大对润滑的要求高，本发明的铝壳拉伸油通过内含的油性剂和极压润滑剂满足冲压润滑需求，但油性剂及极压润滑剂粘附性强，在冲压过程中产生的铝粉容易被粘附，本发明的铝壳拉伸油则通过内含的分剂和清洗剂实现可清洗性，从而实现将冲压过程中铝壳表面残留的铝壳拉伸油和铝粉清洗掉，确保铝壳的成品质量，提高铝壳成品的产品合格率。

洗性能：参考JB/T 4323.2水基金属清洗剂试验方法。
气味：参考HG/T 4065-2008胶粘剂气味检验方法。
评定测试结果参见表3。
表3：
Figure SMS_8
由以上实验数据可知实施例1-9均具有优异的可清洗性、润滑性，并且具有低气味的特点。对比例1-2中，降低或提高硫化肉豆蔻烯酸甲酯，导致润滑性降低或可清洗性变差；对比例3、4中分别降低分散剂的量、清洗剂的量，对比例5采用分子量为550的石油磺酸钠作为清洗剂，得到的铝壳拉伸油组合物可清洗性较差；对比例6采用商用低气味硫化脂肪酸酯SDN-109作为润滑剂，得到铝壳拉伸油组合物清洗性、润滑性及气味明均比较差。
综合以上实验数据，可以看出本发明所提供的一种铝壳拉伸油组合物综合性能优越，具有优异的可清洗性、润滑性，并且具有低气味的特点。
应当理解的是，本发明可用其他的不违背本发明的精神或主要特征的具体形式来概述。因此，无论从哪一点来看，本发明的上述实施例只能认为是对本发明的说明而不能限制本发明，权利要求书指出了本发明的范围，而上述的说明并未指出本发明的范围，因此在与本发明的权利要求书相当的含义和范围内的任何改变，都应认为是包括在权利要求书的保护范围内。
