Description
技术领域
本发明涉及化工领域,具体涉及一种常温浸泡型黄油清洗剂及其制备方法。
背景技术
机械装备的清洗是该部件在进行加工、装配、储存和维修等过程中不可缺少的工艺环节。附着在机械表面的黄油油污的存在,会引起和加速金属腐蚀,降低产品质量,缩短使用寿命。在清洗行业中,要求从业人员在选择清洗剂时,不仅要考虑清洗能力,还要考虑安全环保性,尽量降低对环境的污染,防止清洗剂损害操作人员的健康。目前,工业生产中仍大量使用强碱性清洗剂、有机溶剂(石油溶剂、卤代烃类溶剂等)进行清洗。强碱性清洗剂主要成分是NaOH、Na2CO3、Na2SiO3、Na3PO4、STPP等,清洗能力较差,清洗后零件易生锈,通常用于清洗黑色金属表面的轻度油污和无机盐等污垢。溶剂清洗剂虽然有很强的清洗能力,很容易清洗金属表面的黄油污垢,但大多数易燃,易挥发,而且对人体的中枢神经有较强的刺激性,长期接触会引起神经衰弱、皮肤干裂等疾病。以表面活性剂为主体的水基清洗剂会产生大量泡沫,不易清除,不利于后续操作。
申请号为CN201811542408.6的中国专利公开了一种金属表面重油污清洗剂,该清洗剂由以下质量百分比的原料制备而成:乳化剂15%-25%;渗透剂4%-10%;油污软化剂6%-12%;碱性助剂1%-4%;缓蚀剂0.2-2%,余量水。本发明金属表面重油污清洗剂配方合理,对金属表面上的重机油、黄油等过厚油污有很好的清洗作用,使用效果好,去油污强,生产成本低,无毒副作用,无磷、无污染、无残留,能够满足环保三废要求排放。申请号为CN201610213083.1的中国专利公开了一种金属制品用清洗剂,包括如下组分:超低界面张力表面活性剂、乳酸、乳化剂、酸性清洗剂、酸性缓蚀剂、渗透剂、椰子油脂肪酸二乙醇酰胺、异噻唑啉酮、茶油茶籽粉、有机溶剂以及山梨糖醇。本发明提供一种弱酸清洗剂,该清洗剂清洗效果好,无泡,能够轻易将金属表面上的动物油、矿物油、重机油、黄油等过厚油污除去,清洗后的工件会形成连续水膜;无磷、无污染、无残留,能够满足环保三废要求排放;溶解性强,长期放置不会出现分层和沉淀物,稳定性高的金属制品用清洗剂。这些发明虽然清洗效果好,无污染无残留,但是其对黄油油污的乳化效果不强,乳化时间短,清洗工时较长。
发明内容
针对现有技术的不足,本发明提供了一种常温浸泡型黄油清洗剂及其制备方法,采用独特的复配原料,对黄油有优良的乳化分散效果,利用进口珠碱的高含量起到一定的皂化作用,同时辅助螯合剂对金属离子进行螯合脱离,能达到在常温条件下清洗干净黄油油污。
为实现上述目的,本发明提供了如下技术方案,一种常温浸泡型黄油清洗剂,所含原料及质量百分比如下:
珠碱 5-10%
螯合剂 0.5-3%
三乙醇胺 5-10%
lan-826 0.1-0.5%

赢创重油污表面活性剂 AL 100 10-15%
E-1308 5-10%
金属保护剂 0.1-0.5%
去离子水 加至100%。
优选的,所述金属保护剂为十二烷基苯并三氮唑。
优选的,所述螯合剂为EDTA-4NA。
本发明的另一目的是所述的常温浸泡型黄油清洗剂的制备方法,按如下步骤进行:
1)常温条件下,在反应釜里加入去离子水,然后加入珠碱、螯合剂、三乙醇胺、lan-826,搅拌20-25分钟,至液体搅拌均匀;
2)依次加入仲醇及叔醇多聚合氧乙烯醚、赢创重油污表面活性剂AL 100、 E-1308,加入过程中继续搅拌,直至搅拌均匀;
3)最后加入金属保护剂和余量去离子水,继续搅拌均匀,直至溶液透明均匀即可。
本发明制备的常温浸泡型黄油清洗剂具有以下优点:
本发明产品采用独特的复配原料,对黄油有优良的乳化分散效果,利用进口珠碱的高含量起到一定的皂化作用,同时辅助螯合剂对金属离子进行螯合脱离,能达到在常温条件下清洗干净黄油油污,本发明产品乳化效果强,乳化时间长,能有效缩短清洗工时,同时对钢铁制品无腐蚀,且对钢铁制品具有保护作用。
本发明产品稳定性好、不分层、不浑浊,经过检测各项技术指标见下表1:
