技术领域
本发明涉及保护膜胶带技术领域，具体是涉及一种光学耐温紫外减粘膜。
背景技术
随着便捷性的提升和功能性的完善，手机已经逐步成为人们生活中的必需品之一，手机屏幕也称显示屏，用于显示图像及色彩，制备手机屏幕的玻璃属于特种玻璃，其加工制成工艺很复杂，制成过程已逐步实现机械化。
在现有技术中，完成手机屏幕制成工艺的过程需要利用胶带对玻璃的一面进行承载和保护以适应自动化生产，被保护的面在完成制备工艺流程后需要撕除胶带，撕除后要求无胶带残留且不能破坏玻璃本体。
现有的胶带主要为耐高温的保护膜胶带，它的初黏低，在流水线上进行自动化生产时容易在过程中掉片，而黏着力过大又会造成撕除困难或损坏玻璃的现象，并且，由于需要经过高温工艺来剥离胶带，会导致胶体的分子链被破坏进而在玻璃表面留有残胶，造成玻璃的表面污染，影响良率，增加生产成本。
同时，现有技术中的胶带在制备过程中利用涂布机进行涂布时，胶体涂布不够均匀，胶体涂布和溶剂烘干过程中容易沾染空气中的灰尘而影响胶体黏度，成品良率得不到有效保证；且涂布设备结构较为复杂，流程衔接度不够，严重影响生产效率。

具体实施方式
以下实施例进一步说明本发明的内容，但不应理解为对本发明的限制。在不背离本发明实质的情况下，对本发明方法、步骤或条件所作的修改和替换，均属于本发明的范围。
实施例一
一、光学耐温紫外减粘膜的制备
1、制备丙烯酸酯压敏胶：将5份丙烯酸，20份丙烯酸甲酯，60份丙烯酸丁酯，5份丙烯酸羟乙酯，5份丙烯酸羟丁酯和150份醋酸乙酯加入四口烧瓶，搅拌加热至80℃，滴加偶氮二异丁氰反应至回流温度下保温8 h，降温至50℃后加入10份环氧丙烯酸树脂和2份光引发剂184；
2、将制备完成的丙烯酸酯压敏胶利用减粘膜胶体涂布机涂布在PET基材上，之后在胶体一侧覆上PET离型膜即完成成品的制备。
相关性能测试
1、初粘力测试
初粘力是指物体和胶粘性物质粘性面之间以微小压力发生短暂接触时，胶粘带对物体的粘附作用。通常采用滚球平面停止法的测试原理来评定，将一钢球滚过平放在倾斜板上的胶粘带粘性面。根据规定长度的粘性面能够粘住的最大钢球尺寸（钢球球号1~33），评价其初粘性大小，本次测试同时对本发明制备的减粘膜和常规保护膜的初粘力进行测试，测试角度25°。
检测结果如图2所示，本实施例制备的减粘膜的初粘力为9 号钢球，而常规保护膜的初粘力为2号钢球，说明本实施例制备的产品较现有的常规保护膜而言初粘性有明显提升。
2、UV照射前后的减粘膜黏度测试
测试结果如图3所示，从图中可看出，UV照射前本实施例制备的减粘膜的剥离力为1200g，而经UV照射后剥离力小于20 g，说明UV照射确能造成本实施例制备的减粘膜的黏性消失，本实施例制备的减粘膜具有好撕除的优点。
3、耐温性测试
将制备完成的减粘膜裁出25 cm*100 cm的样片，贴合在玻璃片上，放置20 min后放入130℃烘箱烘烤1 h，拿出静置20 min，用手撕除样片用放大镜观察被贴表面有无残胶。经观察，在玻璃的被贴表面上并无残胶，说明本实施例制备的减粘膜具有较好的耐温性。
实施例二
所述减粘膜胶体涂布机的结构如图4-6所示，在工作台1左端设有PET基材进料辊2、右端设有膜收料辊3，在工作台1上方顺着PET基材7的运动方向依次设有涂胶箱4、烘料箱5和PET离型膜出料辊6；
涂胶箱4的左、右侧壁底部分别设有供PET基材7进出的开口，涂胶箱4的其他侧壁封闭设置，尽可能防止涂胶过程中胶体接触到灰尘以影响后续成品质量；
在涂胶箱4内设有喷枪41，在喷枪41底部设有数个喷胶枪头42，喷胶枪头42位于PET基材7上方且沿PET基材7的宽度方向排布，在涂胶箱4顶部设有供胶箱43，喷枪41与供胶箱43间通过软管连接以方便喷枪41移动，喷枪41活动连接在滑轨44上，滑轨44沿涂胶箱4的宽度方向延伸且其两端与涂胶箱4侧壁固定连接，在涂胶箱4后壁上连接液压缸45，液压缸45的活塞杆穿过涂胶箱4后壁面与喷枪41连接，喷枪41在液压缸45的作用下沿滑轨44做前、后往复运动，在喷枪41沿PET基材7输送方向的一侧设有喷胶压辊46，单个喷胶枪头42在液压缸45作用下进行纵向单向移动的最大距离等于相邻两个喷胶枪头42的喷胶口之间的距离；现有技术中的涂布喷枪大多固定设置，喷枪枪头的喷射点在基材表面连接形成一条直线，但是喷枪喷胶有一个特点，就是喷射中心的胶量较喷射范围内其他区域的胶量要稍多一些，虽后续经过喷胶压辊被压匀铺散开，但还是存在喷射点直线上的胶体量叫其他区域稍多的现象，胶体涂布不够均匀，本发明中公开的喷枪41可沿滑轨44做往复移动，这就使得每一个喷胶枪头42的胶体喷射点在基材上连接后可形成一条S型的曲线，喷射点纵向散开，经过喷胶压辊46后胶体分布会更加均匀，成品质量有进一步地提升。
烘料箱5内嵌设置在工作台1上，烘料箱5紧靠涂胶箱4设置，可进一步起到防止胶料接触空气中灰尘的作用，烘料箱5包括上方的出风装置51、下方的吸风装置52和位于两者间的左右贯通的基材通道53，基材通道53的底面与工作台1的顶面处于同一水平面上便于基材的传输，出风装置51顶部设有热风风箱511、内部设有出风导向装置512，热风风箱511内设有鼓风机5111，鼓风机5111与加热电机5112相连，鼓风机5111的出风口与出风导向装置512的进风管5121相连通，吸风装置52内部底面上设有吸风风机521，吸风装置52底部设有出风管522与外界连通，在基材通道53底面上避开PET基材7的位置设有出风槽与吸风装置52内部贯通形成上下导向的热风循环，热风风箱511内产生的热风从上向下流动对传输中的PET基材7上的胶体内的溶剂进行快速烘干，底部吸风的设置可保证PET基材7紧贴基材通道53的底面运动，防止基材移位和被吹起等意外的发生，影响整个涂布流程的正常进行。
所述出风导向装置512包括布风板5122和设在布风板5122上方的螺旋导流板5123，螺旋导流板5123与进风管5121的内侧壁紧靠设置，螺旋导流板5123的顶面与出风装置51顶面密封连接，在布风板5122上均布数个上下贯通的布风孔5124，螺旋导流板5123对流入的热风起到很好的导向引流作用，热风流动方向如图6中箭头所示，经过导流可避免进风管5121管口的风量大而其他区域风量小的现象发生，导流后的热风经过布风孔5124后均匀地流向PET基材7表面，胶体内溶剂得到全面有效散发，尽可能保证烘料效果的均一性。
在涂胶箱4内的前、后侧底部分别设有一块沿涂胶箱4长度方向延伸的防溢胶刮板47，两块防溢胶刮板47之间的距离与PET基材7的宽度相适应，两块刮板主要是对喷胶压辊46作用后从基材侧边溢出的余胶进行刮除，防止侧边胶量溢出较多。
防溢胶刮板47在长时间工作后其内侧面上会留有大量胶体，胶体发干后会改变板材厚度，进而影响刮胶效果，为了能定期对防溢胶刮板47进行清理，在涂胶箱4内的前、后侧壁底部分别设有一条沿涂胶箱4长度方向延伸的卡接块48，所述防溢胶刮板47的内侧面上与相应一侧的卡接块48对应的位置设有卡接槽，所述防溢胶刮板47与相应一侧的卡接块48可拆卸地卡接连接，工作一段时间后，可将防溢胶刮板47从卡接块48上抽出后拿到外部进行清理，清理工作更加方便进行。
以上显示和描述了本发明的基本原理、主要特征及优点。但是以上所述仅为本发明的具体实施例，本发明的技术特征并不局限于此，任何本领域的技术人员在不脱离本发明的技术方案下得出的其他实施方式均应涵盖在本发明的专利范围之中。
