Description
技术领域
本发明属于金属加工液技术领域,尤其是涉及一种可用于现场添加的切削液生物稳定复合剂及其制备方法。
背景技术
水基切削液在金属加工行业中起着至关重要的作用,其具备良好的润滑性、冷却性、防锈性等,在金属加工行业中得到了广泛的应用。但是水基切削液中的矿物油、脂类润滑添加剂、水等也为微生物菌种提供了理想的滋生环境。生菌腐败的切削液会严重影响其使用性能,并且对机床工件防锈防腐、操作人员的健康等产生危害。而且水基切削液废液不能直接排放,处理费用也十分的高昂,所以许多的企业对切削液的使用年限提出了要求,少则半年,多则一两年。这就对切削液的产品质量提出了更高的要求,延长切削液的体系稳定性及使用寿命尤为重要。
发明内容
有鉴于此,本发明旨在提出一种可用于现场添加的切削液生物稳定复合剂及其制备方法,能够延长切削液的体系稳定性及使用寿命。
为达到上述目的,本发明的技术方案是这样实现的:
一种可用于现场添加的切削液生物稳定复合剂及其制备方法,包括以下重量份的各组分:防锈剂3-20份、抗菌剂8-30份、碱值储备剂5-30份、水8-20份。
优选的,所述防锈剂为三元羧酸、二元妥尔油酸酯、二元酸、乙醇胺硼酸酯、二乙醇胺硼酸酯、三乙醇胺硼酸酯中的一种或两种以上。
优选的,所述抗菌剂为六氢三嗪化合物、碘代丙炔基丁基氨基甲酸酯、乙二醇二羟甲醚、异噻唑啉酮衍生物、吗啉化合物、吡啶硫酮钠中的一种或两种以上。
优选的,所述碱值储备剂为氢氧化钠、氢氧化钾、乙醇胺、二乙醇胺、三乙醇胺、异丁醇胺、正丁胺、异丙醇胺、二甲基乙醇胺、正丙醇胺、二异丙醇胺、N-甲基二乙醇胺、二甘醇胺中的一种或两种以上。
制备上述切削液生物稳定复合剂的方法,包括以下步骤:在40-50℃下,将防锈剂与碱值储备剂加入去离子水中,搅拌至完全溶解,呈澄清透明液体,冷却至室温,然后加入抗菌剂继续搅拌至澄清透明溶液即得切削液生物稳定复合剂。
相对于现有技术,本发明所述的一种可用于现场添加的切削液生物稳定复合剂及其制备方法具有以下有益效果:
1、本发明所述的一种可用于现场添加的切削液生物稳定复合剂,对市面上的水基切削液具有普适相容性,操作简单,可直接在现场进行槽边添加。
2、本发明所述的一种可用于现场添加的切削液生物稳定复合剂,体系中包含的碱值储备剂可保障切削液体系pH值的稳定,有助于黑色金属的防锈、抑制微生物的滋生;防锈剂增强对工件、机床的防锈保护;抗菌剂可在广谱范围上对各类细菌、霉菌进行抑制或消杀,维护切削液体系的正常运行,延长使用寿命,高效且环境友好。
附图说明

图1为本发明实施例的pH值变化趋势图。
具体实施方式
需要说明的是,在不冲突的情况下,本发明中的实施例及实施例中的特征可以相互组合。
下面将参考附图并结合实施例来详细说明本发明。
实施例1
一种可用于现场添加的切削液生物稳定复合剂,包括以下重量份的各组分:三元羧酸10份、二乙二醇胺硼酸酯5份、三乙醇胺12份、二甘醇胺12份、水20份、六氢三嗪化合物25份、碘代丙炔基丁基氨基甲酸酯16份。
实施例2
一种可用于现场添加的切削液生物稳定复合剂,包括以下重量份的各组分:二元酸10份、乙醇胺硼酸酯5份、二乙醇胺15份、乙醇胺9份、水21份、吗啉化合物10份、异噻唑啉酮衍生物20份、吡啶硫酮钠10份。
实施例3
一种可用于现场添加的切削液生物稳定复合剂,包括以下重量份的各组分:三元羧酸10份、二元妥尔油酸脂5份、异丙醇胺12份、N-甲基二乙醇胺12份、水21份、乙二醇二羟甲醚20份、异噻唑啉酮衍生物15份、碘代丙炔基丁基氨基甲酸酯5份。
实验内容:
以某加工制造企业现场液为实验对象,取得现场液pH值7-8之间,外观浑浊,具有一定气味,微生物检测显示存在细菌真菌。
分别通过直接添加实施例1-3的方式调节现场液pH值至9.5,再通过直接添加切削液原液方式调节现场液pH值至9.5作为对比,将获得的四个液各取200ml分别放入500ml试剂瓶中,模拟加工现场环境,分别加入1g铁屑,放入30℃恒温水浴锅中,每天向各试剂瓶中持续通入空气8小时,静置16小时。持续监控四个液的pH值变化,及微生物滋生情况。
在切削液的实际使用过程中,会因为挥发,工件携带,防锈润滑添加剂的消耗等原因,导致液池液位、切削液浓度、切削液pH值下降的情况,需要补充切削液原液来维持现场液的正常使用。因为切削液原液中会有一定比例的杀菌剂,在一定程度上对切削液现场液有修正,预防或消灭细菌真菌,延长使用寿命的作用。但是面对已经存在微生物滋生的现场液,添加切削液原液改善效果持续性不高。
表1微生物检测
微生物检测试验通过市售的测菌片完成,每周进行一次检测,检测各样品微生物滋生情况。
实验结果如图1所示,结果表明,在初始阶段,对比例与实施例1-3均对现场液起到了修正pH值,消灭微生物的作用,但随着时间的增加,仅添加切削液原液的对比例pH值较实施例1-3下降更为迅速,虽均未检测出微生物滋生,但pH的下降,会逐渐形成微生物滋生的理想环境,在试验进行到100天左右,对比例的pH下降到了8.2,且微生物检测表明已存在微生物滋生,而实施例1-3的pH值在8.7左右,未检测出微生物滋生。当试验进行到180天左右,对比例pH值降到了7.6,存在微生物滋生,而实施例1-3的pH下降到8.0左右,先后测出滋生细菌真菌情况,如表1所示。由此可见,通过添加切削液生物稳定剂比直接添加切削液原液,对现场液的修正,维持体系良好状态,延长使用寿命的效果更为优异,实施例1-3相比对比例可延长切削液使用寿命接近一倍时间,其中实施例1效果更优。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
