Description

水性体系可回收保护膜
技术领域
本发明涉及一种保护膜，特别涉及一种水性体系可回收保护膜。
背景技术
玻璃、金属板材、塑料板材等材料在搬运和使用过程中，其表面容易受到接触性污染或磨痕划伤，所以通常采用保护膜覆盖在其表面使之免受损伤和污染。现有技术中所用到的保护膜基本都为平面保护膜，通常情况下它包括基材层、乳着层和离型层。所述的基材层通常为聚碳酸酯、聚乙烯、PET、定向拉伸聚丙烯或是芳族聚醋等材质所组成，基材层为保护膜的主要结构层；黏着层贴浮于基材层的一侧，通常由含有烷氧基硅烷的聚合物或丙烯酸聚合物等所构成，用以将基材层张贴于欲保护的物体表面；而离型层用于保护未使用状态下的保护膜，使用时将离型层去掉将其粘附在物体表面。这样这种普通的平面保护膜由三层构成，成本比较高，且随着湿度、温度和周围环境的其他情况的变化，黏着层容易受潮或受到化学反应产生基材层脱落的现象；当需要更换或者是处理原来的保护膜时候，由于黏着层长时间贴于被贴物会出现残胶现象，不易处理；并且生产和使用保护膜过程中，黏着层的化学材质和离型层会产生大量污染，同时该保护膜也不可以循环使用，不利于节能环保。
发明内容
本发明提供一种水性体系可回收保护膜，此水性体系可回收保护膜实现了EVA胶黏剂层在常温具有粘性和压敏性，且压敏改性EVA胶黏剂层为水性体系环保，无刺激性气味，也方便水性体系可回收保护膜重复利用和回收，大大减少了污染。
为达到上述目的，本发明采用的技术方案是：一种水性体系可回收保护膜，包括PET薄膜、聚丙烯薄膜、压敏改性EVA胶黏剂层和离型材料层，所述压敏改性EVA胶黏剂层位于聚丙烯薄膜和离型材料层之间；
所述压敏改性EVA胶黏剂层由以下组分组成：改性EVA水溶液100份、丙烯酸异辛酯15份、去离子水22份、叔丁基过氧化2-乙基己基碳酸酯6份、亚甲基双苯二胺5份、聚甲基苯基硅氧烷3份、过氧化-2-乙基己基碳酸叔丁酯2.5份、三烯丙基异氰脲酸酯1.4份、萜烯树脂1.3份、烷基酚聚氧乙烯醚0.9份、二甲基亚砜0.8份；
所述改性EVA水溶液进一步通过以下步骤获得：
步骤一、将20~40份聚乙烯醇、6~8份异辛酸钠、2~4份亚硫酸钾盐和0.05~0.1份硫酸亚铁溶解在离子水中形成水性混合物；
步骤二、将步骤一的水性混合物放入高压釜中，再通入乙烯置换出高压釜内的空气；
步骤三、将反应釜夹套水将物料升温至反应温度80℃并搅拌，依次注入单体100份醋酸乙烯酯、10~20份丙烯酸、0.05~1份过氧化二异丙苯、0.25~0.5份叔丁基过氧化氢、0.5~1份焦亚硫酸钠；
步骤四、降温至40℃以下形成所述改性EVA水溶液。
上述技术方案中进一步改进的技术方案如下：
1. 上述方案中，所述步骤二中高压釜的压力为5~10MPa。
2. 上述方案中，所述叔丁基过氧化氢、与焦亚硫酸钠的重量份比例为1：2。
由于上述技术方案运用，本发明与现有技术相比具有下列优点和效果：
1. 本发明水性体系可回收保护膜，其采用丙烯酸并结合硫酸亚铁、聚乙烯醇，改性了由乙烯、醋酸乙烯酯形成的乙烯-醋酸乙烯共聚物，配合丙烯酸异辛酯、亚甲基双苯二胺和叔丁基过氧化2-乙基己基碳酸酯实现了EVA胶黏剂层在常温具有粘性和压敏性，且压敏改性EVA胶黏剂层为水性体系环保，无刺激性气味，也方便水性体系可回收保护膜重复利用和回收，大大减少了污染；其次，进一步加入过氧化-2-乙基己基碳酸叔丁酯、三烯丙基异氰脲酸酯进一步提高了改性EVA胶黏剂层与聚丙烯薄膜的附着力。
2. 本发明水性体系可回收保护膜，其体系中加入烷基酚聚氧乙烯醚、二甲基亚砜能使固体物料更易被水浸湿的物质，通过降低其表面张力或界面张力，使水能展开在固体物料表面上，或透入其表面，而把固体物料润湿；其次，其添加聚甲基苯基硅氧烷改善体系的相容性和表面张力，有利于更好低在涂布过程中实现涂液涂布。
