Description
技术领域
本发明涉及教学用具，具体属于一种擦除白板上炭黑小颗粒的专用清洗液。
背景技术
学校的教学板书用具，传统的是采用粉笔板书，书写完毕进行擦拭时粉尘飞扬，污染教学环境，且对教师和学生的身体健康都有影响。之后，白板逐步取代普通的黑板，而采用白板笔书写，用白板擦进行擦除。目前市面上的白板擦多采用平绒面料，擦拭过程中常常是用水来进行清洗，由于书写所使用的白板笔含有炭黑小颗粒，它会渗透到白板的空隙中，水对其没有清除作用。长此以往，炭黑小颗粒逐渐积累，导致白板留有污迹，越来越难以清除干净，影响白板的使用寿命。
目前，改进以上问题的方案主要是针对白板笔或白板擦，对清洗液的改进未见报道。
发明内容
本发明的目的在于提供一种擦除白板上炭黑小颗粒的专用清洗液，该清洗液不仅能够有效去除渗透进白板缝隙里的炭黑小颗粒，还有消毒灭菌和防冻效果。
本发明提供的一种擦除白板上炭黑小颗粒的专用清洗液，组分按重量百分比计：
无水乙醇：45％-70％
表面活性剂：十二烷基硫酸钠或丙二醇甲醚5％-10％
有机溶剂：乙二醇或丙二醇7％-13％
β-环糊精包合物：0.5％-3.5％
去离子水：15％-30％。
还可以加入香精：0.05％-0.1％。
所述β-环糊精包合物的制备方法：将艾草油、苍术油和丁香油的混合物滴加至温度为37-42℃的β-环糊精饱和水溶液中，混合物和β-环糊精的重量比为2～3:4，包合9-20h后，将温度降至4℃沉淀24-48h，收集沉淀，洗涤、干燥得到β-环糊精包合物。
配方中，无水乙醇能去除炭黑物质；表面活性剂成分有渗透、增溶作用，使乙醇更好的发挥作用；有机溶剂的使用，显著降低液体的冰点，起到防冻效果，也能增强去污效果；香精的加入能掩盖所制清洗液的难闻味道；β-环糊精包合物中艾草油、苍术油和丁香油，能起到杀灭细菌，保护皮肤的作用。
白板专用清洗液的制备方法：
先将无水乙醇和去离子水混合，然后依次加入表面活性剂、有机溶剂、β-环糊精包合物，搅拌至完全溶解即可。
与现有技术相比，本发明具有如下特点：1、本发明提供一种白板专用清洗液，能够有效去除渗透进白板缝隙里的炭黑小颗粒，使白板清洁如新，增加使用寿命。2、本发明提供的白板专用清洗液还在其中加入芳香剂改善气味、加入有机溶剂使其在较冷环境中也能使用。3、在清洗液中含有艾草油、苍术油和丁香油成分，可起到杀菌消毒的作用。
