Description
技术领域
本发明属于铝热轧液技术领域，尤其涉及一种可生物降解的阴离子、非离子混系铝热轧液及其制备方法。
背景技术
现在市面上绝大部分的铝热轧液产品都使用的是矿物油基基础油，矿物油开发及提炼过程产生高的碳足迹，并且矿物油降解率只有20％不到，不容易生物降解，环保性差，矿物油来源比较少，不可再生，且润滑性差消耗量大。此外，现有铝热轧液含有害物质，对环境和水体危害大。
为了实现轧制液在生产和使用过程的中的低碳环保，需要开发生物降解轧制液产品。目前存在使用菜籽油等植物油替代矿物油来配制的切削液，但是此类植物油为基础油的切削液存在易氧化、易变质，寿命短等缺点，无法真正意义上替代矿物油达到金属加工液的各项性能且降低碳排，其乳化剂大多为脂肪醇聚氧乙烯醚类物质，也无法完全生物降解，无法真正意义上可降解。
以合成酯(如对苯二甲酸二辛酯)为基质的铝轧制液，生物降解性好，使用的过程中因为pH值低，没有皂，乳化液稳定，但是因为乳化液pH偏酸性，长期放置容易生菌，所以需要在现场槽边添加杀菌剂，使用不便。
发明内容
本发明的目的在于：提供一种可生物降解的阴离子、非离子混系铝热轧液及其制备方法，铝热轧液不易生菌，同时使乳化液更稳定，减少杀菌剂的使用。
为了实现上述目的，一方面，本发明提供了一种可生物降解的阴离子、非离子混系铝热轧液，包括以下重量百分比的组分：
作为上述技术方案的进一步描述：
包括以下重量百分比的组分：对苯二甲酸二辛酯50％-60％；新戊四醇基多元醇酯20％-60％；磷酸酯1-5％；油酸1-3％；有机胺0.5-2％；甲基苯并三氮唑0.5％-1.5％；石油磺酸盐2％-5％；植物油酸1％-4％；乙氧化脂肪胺2％-4％；聚氧乙烯油酸酯2％-4％；阴离子表面活性剂2％-4％。
作为上述技术方案的进一步描述：
包括以下重量百分比的组分：对苯二甲酸二辛酯53.65％；新戊四醇基多元醇酯25％；磷酸酯3％；油酸2.5％；有机胺0.85％；甲基苯并三氮唑1％；石油磺酸盐3％；植物油酸2％；乙氧化脂肪胺3％；聚氧乙烯油酸酯3％；阴离子表面活性剂3％。
作为上述技术方案的进一步描述：
新戊基多元醇酯基础油为季戊四醇脂肪酸酯。
作为上述技术方案的进一步描述：
阴离子表面活性剂为月桂醇聚醚磷酸酯。
另一方面，本发明还提供了一种可生物降解的阴离子、非离子混系铝热轧液的制备方法，包括以下步骤：
1)根据上述的配比，准备铝热轧液的制备材料；
2)在干净无水的混合罐里加入对苯二甲酸二辛酯53.65％，搅拌并加热到49-55℃；
3)在另一个融固体的容器中加入部分新季戊四醇基多元醇酯5-10％，在搅拌、加热状态下，加入甲基苯并三氮唑1.0％，搅拌至固体融解，加入到混合罐中；
4)在搅拌状态下，在混合罐中加入剩余的新季戊四醇基多元醇酯15-20％，以及乙氧化脂肪胺3％、石油磺酸盐3％，再加入聚氧乙烯油酸酯3％、阴离子表面活性剂3％、植物油酸2％、油酸2.5％、有机胺0.85％、磷酸酯3％，继续搅拌至透明。
作为上述技术方案的进一步描述：
在步骤3)中，搅拌至固体融解时，至少搅拌30分钟，保证混合效果。
综上所述，由于采用了上述技术方案，本发明的有益效果是：
1、本发明中，采用基于DOTP的铝轧制液，生物降解性好，同时组分中极少的有机酸和有机胺生成了有机皂，再加上磷酸酯，增强了积压润滑能的同时，提高了乳化液的pH，形成一个pH的缓冲体系，保护乳化液长期使用，抑制了细菌的生成，不易生菌，同时使乳化液更稳定，减少杀菌剂的使用，形成乳化混系。
2、本发明中，通过原料筛选，在轧制液配方中使用任意比例的DOTP代替不易降解的矿物油。DOTP与本配方中的其它聚合物添加剂可以一起成为可降解吸收生物高分子材料，生物降解材料的最终产物为二氧化碳和水。DOTP的各项性能技术参数等同于或优于矿物油，但DOTP降解率100％,同比矿物油降解率提高80％，环保低碳。使用DOTP作为轧制液的主要原料，加工过程中不会产生大量烟雾油雾，保持加工车间清净无异味，更加环保。此外，从源头追寻DOTP生产的碳排放，其排放量大大降低(相较于矿物油生产的碳排放)。
3、本发明中，轧制液使用易生物降解乳化剂，不含有害物质(如甲醛、二环己胺、亚硝、苯酚及苯酚类杀菌剂和VOC挥发性物)，环保且安全性高，易于生物降解。
4、本发明中，轧制液组分中，季戊四醇脂肪酸酯属于新戊基多元醇酯类的基础油，不仅满足可再生和生物可降解这两方面的要求，还具有石油基润滑油的优越性能：1)具有较宽的液体范围，较高的黏度指数，优良的黏度性能和低温性能；2)热安定性好，热分解温度在340℃以上；3)分子结构中含有较高活性的酯基基团，易于吸附在金属表面形成牢固的润滑油膜，具有较好的摩擦润滑特性。
5、本发明轧制液组分中，月桂醇聚醚磷酸酯微溶于水，在轧制辊缝区容易析出，提供极压润滑。

C)乳化液稳定性ESI比较实验：
二、结论(对比实验结果)：
A)三种产品的乳化液稳定性ESI能均达到非离子乳化液稳定性的要求，三个产品之间的差别不大。
B)DOTP基非离子乳化液的颗粒度比Base Oil基非离子乳化液的颗粒度小，说明以DOTP为基础油产品的乳化性能更好。
C)Hybrid产品是在DOTP基产品的基础上进一步优化，在保留DOTP优势的基础上，通过引入阴离子和微量的有皂技术，使产品更加稳定，抑菌性更好，极压润滑性能更强。
总的来说，通过原料筛选，在轧制液配方中使用任意比例的DOTP代替不易降解的矿物油，DOTP的各项性能技术参数等同于或优于矿物油，但DOTP降解率100％,同比矿物油降解率提高80％，环保低碳。使用DOTP为主要原料的轧制液，金属保护性好，能满足轧制工艺的需要，并且产品稳定，润滑性好，可以降低使用浓度2-3％，对于使用量极大的轧制液来说，有效节约成本。使用DOTP作为轧制液的主要原料，加工过程中不会产生大量烟雾油雾，保持加工车间清净无异味，更加环保。此外，从源头追寻DOTP生产的碳排放，与矿物油生产的碳排放相比，其排放量大大降低。轧制液使用易生物降解乳化剂，不含有害物质(如甲醛、二环己胺、亚硝、苯酚及苯酚类杀菌剂和VOC挥发性物)，环保且安全性高，易于生物降解。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
