Description
技术领域
本发明实施例属于清洗剂技术领域，尤其涉及一种用于手机盖板玻璃的中性清洗剂。
背景技术
AF(anti finger)膜也称作防指纹膜，是一种含氟材料，一般称作全氟聚醚，其表面张力极低，具有疏水、疏油特性。AF膜可让触摸屏不易沾染指纹油污等，保持手机屏幕的顺滑与干净。因此，玻璃表面镀AF膜技术在触摸屏制造领域被广泛使用。
工业生产中，玻璃镀AF膜后，在进行下一个加工工序前，需要先洗净表面的脏污和富余的AF油，清洗方法一般是将清洗剂用水稀释后进行喷淋滚刷清洗，但清洗后会出现白斑，影响后序加工。
因此，急需研发一种清洗后不会出现白斑的清洗剂已经是当务之急。
发明内容
本发明实施例的目的是提供一种用于手机盖板玻璃的中性清洗剂，为了解决现有清洗剂清洗后会出现白斑，影响后序加工的技术问题。
为了实现上述目的，本发明采用了如下技术方案：
本发明实施例公开了一种用于手机盖板玻璃的中性清洗剂，该清洗剂包括下列重量份的原料:络合剂2-5份，分散剂10-15份，表面活性剂2-8份，抑泡剂0.05-1份，特种表面活性剂1-3份,补足去离子水至100份。

本发明实施例还公开了所述络合剂为乙二胺四乙酸、二乙基三胺五乙酸、二乙烯三胺五乙酸、次氮基三乙酸钠、亚氨基二琥珀酸四钠中至少两种的混合物。
本发明实施例还公开了所述分散剂为聚丙烯酸钠、水解聚马来酸酐、聚苯乙烯磺酸钠中至少两种的混合物。
本发明实施例还公开了所述抑泡剂为乙二醇单丁醚、乙二醇单甲醚、二乙二醇单甲醚、二乙二醇单丁醚、磷酸三丁酯中的一种或两种。
本发明实施例还公开了所述表面活性剂为异构醇聚氧乙烯醚和脂肪醇聚氧乙烯醚的混合物，且异构醇聚氧乙烯醚和脂肪醇聚氧乙烯醚的比例为8:2到5:5。

测试方法：取镀膜后的手机盖板玻璃，在同等工艺条件下在超声波清洗槽中清洗，并经过5道纯水洗后，热风吹干，观察表面状态。并按照以下等级区分(其中腐蚀情况以玻璃表面以及摄像头小孔观察)，见下表1：
将上述实施例得到的产品进行测试。
测试结果见下表2：
| 实施例 | 膜层状态 | 表面白斑残留状态 |
| 实施例1 | A1 | B1 |
| 实施例2 | A1 | B1 |
| 实施例3 | A1 | B1 |
| 实施例4 | A1 | B1 |
| 实施例5 | A1 | B1 |
从表2可得出含氟-聚醚改性有机硅表面活性剂，表面张力小于18mN/m，具有极高的清洗能力，有效避免了清洗后白斑问题。
本产品抑泡剂为乙二醇单丁醚、乙二醇单甲醚、二乙二醇单甲醚、二乙二醇单丁醚、磷酸三丁酯中的一种或两种作为消泡成分，既不腐蚀玻璃表面的抗指纹膜层，又能够抑制泡沫产生，有效避免了含硅类消泡剂残留的现象，达到无残留、低泡、易漂洗的效果。
得到的产品中性，复配高效的分散剂，达到了碱性的清洗效果，同时避免损伤抗指纹膜层，对其水滴角和耐磨性等无破坏作用。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
