Description
技术领域
本发明涉及清洗剂技术领域，尤其涉及一种光学镜片清洗剂。
背景技术
光学镜片具有较好的透光率和机械化学性能，是光学器材如照相机、摄像机、投影机、幻灯机、显微镜等的重要组成部分。近几年数码技术飞速发展，给光学镜片的发展提供了一个广阔的空间。光学镜片在生产和使用过程中不可避免的会沾上油污、灰尘、指纹、水湿性污物等，这些污染如不及时彻底清除，会影响其成像、透光率，会使镜片发雾、发霉、直接影响到光学仪器的使用寿命，因此，光学镜片的清洗就显得尤为重要。
市面上现有的光学镜片清洗剂在清洗时存在以下几个缺点：(1)清洗不干净，在清洗后会有残留的斑或者是气雾，无法达到最佳的清洁效果；(2)热稳定性较差，在温度偏高的储存条件下，会发生分解导致清洗剂失效或者易燃；(3)化学安全性较差，清洗剂组分中含有氯化物及低芳香烃等物质，毒性较大；(4)不环保，清洗剂组分中含有卤素成份，因此会破坏臭氧层，不可直接排放。
发明内容
基于背景技术存在的技术问题，本发明提出了一种光学镜片清洗剂，不含有毒及腐蚀性成分，去污力强，清洗后不留白斑、不起雾。
本发明提出的一种光学镜片清洗剂，其原料按质量百分比计，包括：月桂醇嵌段聚醚表面活性剂10-15％、椰子油脂肪酸二乙醇酰胺4-8％、葡萄糖酸钠5-10％、乙二醇单丁醚5-10％、乙醇5-10％、山梨糖醇3-7％、三乙醇胺5-10％、碳酸钠3-6％、消泡剂1-3％，余量为去离子水。
优选地，所述月桂醇嵌段聚醚表面活性剂的制备如下：将月桂醇和催化剂加入到反应釜中，采用氮气置换反应釜中空气3次，升温至135-145℃，加入环氧乙烷，加入过程中保证反应釜内压力恒定，滴加完毕后保持25-35min，然后加入环氧丙烷，加入过程中保持反应釜内压力恒定，滴加完毕后保持25-35min，再加入环氧乙烷，加入过程中保持反应釜内压力恒定，滴加完毕后保持30-40min，停止反应，中和反应体系至中性，出料，即得月桂醇嵌段聚醚表面活性剂。
优选地，所述催化剂为氢氧化钾，其用量为月桂醇质量的0.1-0.3％。
优选地，所述月桂醇、环氧乙烷、环氧丙烷的质量比为1：3-4：1-1.5，所述两次环氧乙烷的用量质量比为4-5：3。
优选地，加入环氧乙烷、环氧丙烷过程中保持反应釜内压力为0.3-0.4MPa。
优选地，所述消泡剂为聚氧丙烯甘油醚或聚氧丙烯聚氧乙烯甘油醚。
上述光学镜片清洗剂的制备方法如下：向去离子水中加入月桂醇嵌段聚醚表面活性剂、椰子油脂肪酸二乙醇酰胺、葡萄糖酸钠、乙二醇单丁醚、乙醇、山梨糖醇、三乙醇胺、碳酸钠、消泡剂，搅拌溶解，即得。
上述光学镜片清洗剂在使用时，用去离子水稀释10-15倍，然后用于光学镜片的清洗。
有益效果：本发明提出了一种光学镜片清洗剂，不含硫、苯等有毒及腐蚀性物质，环保，其组分中的月桂醇嵌段聚醚表面活性剂去污力强、稳定性好，易于生物降解，和椰子油脂肪酸二乙醇酰胺配伍，水溶性好，渗透去污，加入的葡萄糖酸钠和山梨糖醇能够螯合水溶液中的金属离子，防止沉淀产生，提高体系的稳定性能，三乙醇胺和碳酸钠配合作用，对油污进行皂化，并对油污进行分散、润湿、渗透，且还能附着在玻璃表面保护基材不受损伤；本发明的清洗剂适用于成像元件、光学镜片等玻璃材质的清洗，可有效去除其表面的研磨剂、指纹、油污、粉尘等污渍，去污力强，清洗后不留白斑、不起雾，残留少。使用时，用去离子水稀释10-15倍后使用，配合浸泡、超声波清洗使用效果更佳，对光学玻璃基材无损伤，且该清洗剂热稳定好，长期放置不易分解。
月桂醇嵌段聚醚表面活性剂制备中，在催化剂的作用下，月桂醇在无水和无氧气存在情况下先与环氧乙烷开环聚合反应，再依次与加入的环氧丙烷和环氧乙烷反应，得到EO/PO/EO嵌段聚醚非离子表面活性剂，并控制环氧乙烷二次加入量以及环氧丙烷的加入量，调整分子链中亲水基聚环氧乙烷段和亲油基聚环氧丙烷段的含量，制得的该非离子表面活性剂稳定性高、水溶性好，易于生物降解，且由于亲水亲油基团交错排列，空间相互阻碍，形成大量液膜空隙减弱了液膜强度，形成的泡沫易破裂，具有低泡的性能，且其在水溶液中更易形成胶束，表面张力较大，具有很好的润湿、乳化及去污性能，与其它表面活性剂的配伍性好。
