Description

一种屏幕用水性罩光清漆组合物及其制备方法和应用 技术领域
本申请涉及涂料技术领域，尤其涉及一种屏幕用水性罩光清漆组合物及其制备方法和应用，还涉及由这样的水性罩光清漆组合物制得的漆膜及其应用。
背景技术
随着智能手机的兴起，手机贴膜也应运而生，手机贴膜市场五花八门，目前常用的有两种，PET和钢化玻璃。
PET，中文名为聚对苯二甲酸乙二醇酯。该材料薄膜具有强度高、透光性好、无色无味无毒、韧性好的优点，拥有较好的耐磨、耐折叠特性。生活中的各类盛装食品饮料的塑料容器，基本都是这种材料。PET材质贴膜的特性与聚丙烯(PP)和聚乙烯(PE)类材质相比较，它质地较硬、不会出现泛黄现象，并且由于不需要胶水粘贴，可以用刮卡赶出气泡。此外，它还可以反复使用，只需将其清洗干净即可。
钢化玻璃贴膜，采用耐磨特性好、强度高、硬度高的钢化玻璃，能够对手机屏幕有较高级别的安全保护。钢化玻璃是一种预应力玻璃，通常采用物理或化学方法，在玻璃表面形成压应力，在承受外力时需要首先抵消表层应力，从而提高承载能力，增强自身抗压性和抗冲击性。
然而，不同手机屏幕的尺寸不同导致手机贴膜不能通用，而手机更新换代很快，由此产生极大的贴膜库存浪费。
发明概述
为解决上述技术问题，本申请提供一种屏幕用水性罩光清漆组合物及其制备方法和应用。所述组合物在制作漆膜时具有涂料易施工、快速成型的特点，从而实现客户定制形状的功能，并且这样的漆膜具有耐脏污、抗划伤、防爆等功能，同时还提高了漆膜表面冲击强度和耐沾污性，使得抗指纹的功 能得以实现。
为了达到本申请目的，本申请提供了一种水性罩光清漆组合物，所述组合物包含按质量份数计的如下组分：水性丙烯酸乳液50份-65份，脂肪族异氰酸酯5份-10份，纳米结构PE蜡粉2份-15份，助剂2份-8份，水5份-30份，增稠剂0.5份-3.0份以及分散剂0.4份-1.0份。
在一些实施方式中，所述组合物可以包含按质量份数计的如下组分：水性丙烯酸乳液60份-65份，脂肪族异氰酸酯8份-10份，纳米结构PE蜡粉8份-10份，助剂3份-7份，水8份-25份，增稠剂0.7份-2.5份以及分散剂0.4份-0.8份。
在一些实施方式，所述组合物可以由按质量份数计的如下组分组成：水性丙烯酸乳液50份-65份，脂肪族异氰酸酯5份-10份，纳米结构PE蜡粉2份-15份，助剂2份-8份，水5份-30份，增稠剂0.5份-3.0份以及分散剂0.4份-1.0份。
在一些实施方式中，所述组合物可以由包含按质量份数计的如下组分组成：水性丙烯酸乳液60份-65份，脂肪族异氰酸酯8份-10份，纳米结构PE蜡粉8份-10份，助剂3份-7份，水8份-25份，增稠剂0.7份-2.5份以及分散剂0.4份-0.8份。
在一些实施方式中，所述水可以为去离子水，或其他经过净化处理的水，比如纯净水。
在一些实施方式中，所述助剂可以包括：助溶剂2-6份、中和剂0.1-0.2份、消泡剂0.2-0.5份、流平剂0.4-1.0份和基材润湿剂0.3-0.5份。
在一些实施方式中，所述助剂可以由如下组成：助溶剂2-6份、中和剂0.1-0.2份、消泡剂0.2-0.5份、流平剂0.4-1.0份和基材润湿剂0.3-0.5份。
在一些实施方式中，所述助溶剂可以为符合相关标准要求的助溶剂即“环保助溶剂”。
在一些实施方式中，其中所述水性丙烯酸乳液可以为市售的丙烯酸分散体A2743或者万华化学L4501。

申请人在实验过程中发现，当水性丙烯酸乳液相对脂肪族异氰酸酯的比例过低时，致密度不够，漆膜的硬度、耐冲击耐污性较差，过高时硬度太高影响附着力。另外丙烯酸乳液总量少的话也会影响最终耐候性能。在一些实施方式中，所述水性丙烯酸乳液与所述脂肪族异氰酸酯的重量比可以为65:10-60:8。
本申请的发明人还发现，纳米结构PE蜡粉的添加量过少不能起到很好的抗指纹性能，添加量也不是越多越好，超过一定比例时反而会影响漆膜的透明性和附着力等性能。在一些实施方式中，所述纳米结构PE蜡粉占总的组合物的质量分数可以为8％-10％。
在本申请使用的所有的原料均可市购获得。
此外，本申请还提供了一种制备如上所述的水性罩光清漆组合物的方法，所述方法可以包括以下步骤：

步骤b，按照所述原料配比，在步骤a的混合物中加入水性丙烯酸乳液，以500r/min的速度搅拌5分钟；然后将助溶剂、中和剂、配方量的去离子水的第二部分约30％依次加入到备料锅中，900r/min的速度搅拌10分钟；然后陆续加入消泡剂、流平剂、基材润湿剂，1200r/min的速度搅拌10分钟。
步骤c，按照所述原料配比，在步骤b的混合物中依次加入增稠剂、剩余水，1000r/min的速度搅拌20分钟，调整粘度至90-100KU。
步骤d，施工前4h，按照所述原料配比，将脂肪族异氰酸酯加入到步骤c的混合物中，900r/min的速度搅拌5分钟，得到最终组合物。
对实施例1-8制备的水性罩光清漆组合物进行施工喷涂后对制备的涂层(即漆膜)性能进行性能检测(其中涂层测试是将实施例1-8制备的水性罩光清漆组合物涂覆在根据相关检测标准所规定的底层上，然后进行测试)，检测标准：
施工黏度通过参考国家标准《GB-T 9269-1988建筑涂料粘度的测定斯托默粘度计法》；
硬度通过参照国家标准《GB/T 6739-2006色漆和清漆铅笔法测定漆膜硬 度》来测试；
附着力通过参考国家标准《GB/T 1720-1979漆膜附着力测定法》来测试；
抗冲击性通过参考国家标准《GB/T 1732-1993漆膜耐冲击测定法》来测试；
柔韧性通过参照《漆膜柔韧性测定法》(GB/T 1731-1993)来测试；
耐候性通过参考国家标准《GB/T 1765-1979(89)测定耐湿性﹑耐盐雾﹑耐候性(人工加速)的漆膜制备法》来测试；
耐沾污性通过国家标准《GB/T 9780-2013建筑涂料涂层耐沾污性试验方法》来测试；
漆膜抗指纹性能通过SITA清洁度仪测量手指按压涂膜并经过超声波清洗后的玻璃表面清洁度来衡量；
漆膜透明度可以通过光电比色计测定透光率来衡量。
检测结果见表2；

备注：附着力和耐沾污从0-5级依次降低，0级最好，五级最差，三级基本合格。柔韧性数值越低表示抗弯曲程度越好，柔韧性越好。抗冲击性数 值越高说明耐磨性越好。漆膜抗指纹性能通过SITA清洁度仪测量手指按压涂膜经过超声波清洗后的玻璃表面清洁度来衡量，清洁度以RFU绝对值表示，数值越高，清洁度越差(一般高透明玻璃RFU值为70，RFU在约85或85以下一般视为可以接受值)。透明度以光电比色计测定透光率来衡量(0-100％)，数值越高透明度越好。
本申请所形成的漆膜可以达到3H硬度，乃至4H的硬度，具有很好的抗冲击性和强度，并且可以达到高透明玻璃的透明效果(透明度值能达到90％以上，与之相比常用的PET和钢化玻璃RFU值一般在90左右)；并且柔韧性好(弯曲性小于2mm，与之相比PET和钢化玻璃硬度高柔韧性差，一般弯曲性在5mm)，可以应用于目前最流行的柔性折叠屏幕的保护。最重要的是本申请的漆膜具有可塑性，可以根据客户要求任意地定制尺寸和形状，现场喷涂干燥成型，喷涂后经过70摄氏度低温烘烤，15-30分钟即可成型，避免了由于电子产品更新换代快导致的过量库存积压，实现资源的有效利用。
虽然本申请所揭露的实施方式如上，但所述的内容仅为便于理解本申请而采用的实施方式，并非用以限定本申请。任何本申请所属领域内的技术人员，在不脱离本申请所揭露的精神和范围的前提下，可以在实施的形式及细节上进行任何的修改与变化，但本申请的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
