Description
技术领域
本发明涉及一种保护膜及其制备方法，属于保护膜制备技术领域。
背景技术
保护膜现已成为一种非常重要的软包装材料，被广泛应用于产品运输过程中的表面保护和制程过程中的表面保护；各类金属、薄膜、胶带的模切保护及转贴和保护；各类光学玻璃加工表面保护；各类塑胶机壳、键盘等塑料件保护。随着GB33372-2020《胶黏剂挥发性有机物限量》的落地实施，国家对胶黏剂中挥发性有机物含量的管控越来越严格，传统的涂料行业基本已陆续切换为水性涂料为主，胶黏剂行业也在向水性胶黏剂、热熔型胶黏剂，紫外光固化胶黏剂等无溶剂方向发展。保护膜产品在生产过程中，经常因不良外观导致产品不合格而报废，产生了报废品以及后续的危废处理。因此，开发出一种水性可重工的保护膜来替换部分溶剂型保护膜的应用就显得很有必要了。
例如，专利CN109868074A公开了一种生物可降解保护膜及其制备方法，通过添加相容剂改善了聚乳酸与聚丙烯、聚乙烯之间的相容性，使制得的聚乳酸/聚丙烯/聚乙烯基材层具有较好的加工性能和物理性能，同时，由于聚乳酸的存在，使用废弃后的保护膜能在自然环境中进行生物降解，减少对环境的污染。使用该方法制备的产品，降解周期长。
又如专利（CN 111410919 A 江西蓝海芯科技集团有限公司）公开了一种便于回收利用的保护膜，通过选用聚天门冬氨酸树脂脲与改性橡胶制得胶粘层，回收时混合造粒，使用该方法制备的产品，回收造粒回填消耗慢且造粒工艺设备成本高。
再比如，专利（CN 102218873 A 太仓新宏电子科技有限公司）公开了一种用于玻璃、金属板材或塑料件表面的保护膜，通过网纹聚乙烯材料涂布压敏胶贴合PET离型膜制作成品实现对模切材料的表面保护。该产品出现生产不良时，无法实现可重工性。
发明内容
本发明的目的在于提供一种保护膜及其制备方法，旨在解决现有技术中存在的无法实现重工性、保护膜降解周期长、有机添加剂易污染环境且生产设备成本高等问题。
为解决上述技术问题，本发明是采用下述技术方案实现的：
一种保护膜，所述保护膜由胶黏剂涂覆在基材表面并经干燥制得，所述胶黏剂按重量份数计，包括改性葡萄糖乳液100重量份、消泡剂0.5-3.0重量份、流平剂0.5-5.0重量份、固化剂0.5-10重量份、防腐剂0 .1-1重量份、去离子水10-40重量份。
进一步的，所述改性葡萄糖乳液的原料组成包含葡萄糖乳液和丙烯酸共聚物。
进一步的，所述丙烯酸共聚物包括由丙烯酸、甲基丙烯酸羟乙酯、丙烯酸羟丙酯、丙烯酸丁酯、丙烯酸异辛酯、丙烯酰胺以及丙烯酸甲酯中至少两种制得的共聚物。
进一步的，所述消泡剂为聚醚类消泡剂、高级醇及其衍生物、含有非离子型部分的脂肪族碳氢化合物中的任意一种。
进一步的，所述流平剂为为表面活性剂、聚丙烯酸或羟甲基纤维素中的任意一种。
进一步的，所述固化剂为聚异氰酸酯或氮丙啶。
进一步的，所述防腐剂为甲醛及其衍生物、苯并咪唑、异噻唑啉酮或氯乙酰胺中的任意一种。
本发明第二个目的是提供一种如权利要求1-7任一所述保护膜的制备方法，包括以下步骤：
制备改性葡萄糖乳液；在搅拌均匀后的乳化剂和去离子水的混合液中，加入丙烯酸共聚物和葡萄糖，搅拌均匀后制得预乳液；将去离子水、乳化剂和缓冲剂混合加热，温度稳定后加入部分预乳液进行反应，反应结束后滴加剩余的预乳液和引发剂，继续进行反应；反应结束后先进行保温，然后降温到60℃以下，使用氨水中和PH值至7-8之间，加入增稠剂以及适量的消泡剂和润湿剂，制得改性葡萄糖乳液；
在改性葡萄糖乳液中加入消泡剂、流平剂、固化剂、防腐剂以及去离子水，搅拌均匀后制得胶粘剂；
在基材电晕面涂覆胶黏剂层，经干燥复合、收卷、静置后得到保护膜；
上述滴加预乳液和引发剂的步骤中，保持引发剂晚于预乳液5 min滴加完毕。
与现有技术相比，本发明所达到的有益效果是：
（1）采用改性葡萄糖乳液和丙烯酸共聚物制备的胶黏剂涂覆的保护膜，产品性能与溶剂型保护膜产品性能相当，并可减少乙酸乙酯、甲苯等挥发性有机溶剂的排放，保护环境；
（2）本发明在胶黏剂中添加特制的改性葡萄糖乳液，由此制成的保护膜具有葡萄糖的可降解性，实现可重工的作用，且能牢固的贴覆在各种材料表面；
（3）原材料容易获得，且成本较低，同时可重工性简单便捷，节省基材损耗；
（4）清洗介质可以循环使用，绿色节能。
具体实施方式
下面对本发明作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案， 而不能以此来限制本发明的保护范围。
实施例1
首先制备改性葡萄糖乳液，在搅拌均匀后的乳化剂和去离子水的混合液中，加入丙烯酸共聚物和葡萄糖，搅拌均匀后制得预乳液；将去离子水、乳化剂和缓冲剂混合加热，温度稳定后加入部分预乳液进行反应，反应结束后滴加剩余的预乳液和引发剂，继续进行反应；反应结束后先进行保温，然后降温到60℃以下，使用氨水中和PH值至7-8之间，加入增稠剂以及适量的消泡剂和润湿剂，制得改性葡萄糖乳液；
接着将改性葡萄糖乳液100重量份、消泡剂0.5重量份、流平剂0.5重量份、固化剂0.5重量份、防腐剂0.1重量份、去离子水10重量份采用“一锅法”直接混合搅拌均匀制得胶黏剂。选取50 μm的PET基材层，在基材层的电晕面上涂布胶黏剂，形成胶黏剂层，胶黏剂层的厚度为10 μm，将整个基材层放入烤箱，温度设置仅需保证胶黏剂溶剂中的水烘烤完全即可。烘烤完全后将基材层复合收卷，在常温下静置24小时，静置后进行测试，分切出货。
实施例2
和实施例1不同的是，胶黏剂的制备原料为改性葡萄糖乳液100重量份、消泡剂1.0重量份、流平剂1.5重量份、固化剂3重量份、防腐剂0.3重量份、去离子水20重量份。
实施例3
和实施例1不同的是，胶黏剂的制备原料为改性葡萄糖乳液100重量份、消泡剂2.0重量份、流平剂3.0重量份、固化剂6.0重量份、防腐剂0.6重量份、去离子水30重量份。
实施例4
和实施例1不同的是，胶黏剂的制备原料为改性葡萄糖乳液100重量份、消泡剂3.0重量份、流平剂5.0重量份、固化剂10.0重量份、防腐剂1.0重量份、去离子水40重量份。
测试例1
对于实施例1-4的测试方法为粘着力测试，参照ASTMD3330，其中采用贴敷的样品为钢板、玻璃、PP板以及PE板，贴敷后放置72小时，无残胶为合格，测试结果列在表1中：
表1. 粘着力测试表
由实验数据可知，本发明所制备得到的保护膜具有良好的粘着力可调节性能，并且在贴敷不同基材不会出现残胶、脱胶的现象，且由于在保护膜中添加了葡萄糖制备的改性葡萄糖乳液，使得保护膜在生产中出现异常，可以直接冲洗胶面，去除涂布胶面；膜面烘干后，可以重新涂布生产；工艺简易，方便操作，实现在线重工利用。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和变形，这些改进和变形也应视为本发明的保护范围。
