Description

一种脱水防锈油 技术领域
本发明涉及一种脱水防锈油。
背景技术
金属制品制造过程中，会使用水性切削液和清洗剂等水性介质，上述介质会在金属表面形成水膜。脱水防锈油可以迅速脱除金属表面的水膜，同时沉积上一层防锈油油膜，从而减少金属制品清洗烘干工序。
目前脱水防锈油广泛应用于金属制品制造过程中，脱水防锈油中脱水剂是影响脱水防锈油脱水性能的重要因素。1952年US2647839中披露使用4到8碳的脂肪醇与0.1％～3％水溶性表活配伍，作为脱水组合物，用于金属表面水的去除。1961年H.R.Baker使用80％～100％的正丁醇作为脱水剂用于进水设备的脱水(NRLREPORT 5606)。2016年CN 105238520中披露在基础油中加入少量的醚类、醇类或醇醚，从而达到脱水效果。为了达到脱水效果，现有脱水剂所使用的醚类、醇类或醇醚等物质都具有一定的水溶解性，但脱水防锈油中进入大量水后，脱水剂容易被消耗或乳化，从而影响脱水防锈油的长期使用。
发明内容
发明目的：本发明提供一种能够高效脱水且可以延缓大量水混入导致脱水剂脱水性能快速下降的脱水防锈油。
技术方案：本发明所述的脱水防锈油，包括如下质量份数的组分：0.5～10份氧化蜡丁酯、0.5～10份辅助剂、0～10份油溶性磺酸盐以及78～94份基础油；其中，所述辅助剂为醇醚溶剂、醇类或乳酸酯中的至少一种。
其中，所述氧化蜡丁酯的皂化值≥50mgKOH/g，滴熔点为30～60℃；皂化值越高，说明含的亲水性基团越多，从而使金属表面的水越容易脱除，同时滴熔点低，能够实现在体系中良好的溶解分散。
其中，所述醇醚溶剂为乙二醇单丁醚、丙二醇单丁醚、二乙二醇单丁醚或二丙二醇单丁醚；所述醇类为碳数在4～13之间的直链或异构醇；所述乳酸酯为乳酸乙酯或乳酸丁酯。
其中，所述油溶性磺酸盐为二壬基萘磺酸钡或/和二壬基萘磺酸钙；壬基萘磺酸钡为碱性或中性二壬基萘磺酸钡；二壬基萘磺酸钙为碱性或中性二壬基萘磺酸钙。
其中，所述基础油为馏程在180～250℃的溶剂油。基础油的馏程越低，体系的粘稠度越低，从而使体系的脱水效果更好，一方面利于水离开金属表面，一方 面利于水沉降在体系中。
本法明脱水防锈油制备过程如下：将氧化蜡丁酯加热为油状液体，在调和釜中加入配方量的基础油，再加入配方量的辅助剂和油溶性磺酸盐，在40-60℃下搅拌1h即可。
有益效果：本发明脱水防锈油使用氧化蜡丁酯协同辅助剂作为脱水剂，能够实现在短时间(10s)内的高效脱水，脱水率可高达100％，同时还可以有效延缓大量水混入后导致脱水剂脱水性能快速下降的问题；本发明脱水防锈油将金属表面附着的大量水或水溶液直接脱除，能够解决金属制品制造过程中金属表面附着大量的水或水溶液，从而可以不经过烘干，直接浸泡防锈油或其它油品。
具体实施方式
实施例1
本发明脱水防锈油，包括如下质量份数的组分：3份氧化蜡丁酯、1份乙二醇单丁醚、2份碱性二壬基萘磺酸钡以及94份D60。
实施例2
本发明脱水防锈油，包括如下质量份数的组分：10份氧化蜡丁酯、5份乙二醇单丁醚、5份正丁醇、2份中性二壬基萘磺酸钡以及78份D60。
实施例3
本发明脱水防锈油，包括如下质量份数的组分：1份氧化蜡丁酯、1份乳酸乙酯、1份正己醇以及97份D60。
实施例4
本发明脱水防锈油，包括如下质量份数的组分：2份氧化蜡丁酯、2份二丙二醇单丁醚、1份乳酸丁酯、2份中性二壬基萘磺酸钙以及93份D60。
对比例1
一种脱水防锈油，包括如下质量份数的组分：10份氧化蜡丁酯、2份中性二壬基萘磺酸钡以及88份D60。
对比例2
一种脱水防锈油，包括如下质量份数的组分：5份乙二醇单丁醚、5份正丁醇、2份中性二壬基萘磺酸钡以及88份D60。
对比例3
一种脱水防锈油，包括如下质量份数的组分：40份乙二醇单丁醚、40份正丁醇、2份中性二壬基萘磺酸钡以及18份D60。
使用水性清洗剂将7片标准金属试片表面清洗干净，然后用自来水冲洗金属试片表面，使金属试片表面可以形成连续的水膜。将七片金属试片分别垂直放入 装有实施例1～4和对比例1～3的脱水防锈油烧杯中，金属试片需要全部浸没在油中。记录金属试片表面水脱去>95％的时间以及金属试片表面最终水残留情况，见表1。
表1
通过表1可知，实施例2的脱水防锈油可以脱水对应油液体积500倍的水，对比例1～2脱水性能本身就很弱，对比例3在提高辅助剂剂量后虽然可以实现脱水，但经过5倍体积水后，脱水性能就会明显下降。本发明脱水防锈油可以用于金属制品表面的水或水溶性物质的去除，该脱水防锈油具有良好的脱水效果，同时也可以有效延缓大量水混入导致脱水性能下降的问题，可用于钢管制造过程、汽车零部件制造过程的脱水工序。
