Description
技术领域
本发明涉及光触媒领域，具体的讲，是涉及一种光触媒键盘贴。
背景技术
随着信息化发展，计算机的迅速普及，计算机作为一种公共设备，使用率非常高，经过调查发现，在人员流动量大的公用场合，如网吧、图书馆、医院等地，计算机的键盘成为藏污纳垢之所和细菌传染的源头。
据研究人员通过实验发现，在调查的80台公共计算机和个人计算机细菌污染率达100％，除了缝隙中藏匿着饼干渣、咖啡粉、头发等杂物外，棉签采样后还培养出了真菌、大肠埃希菌、金黄色葡萄球菌、表皮葡萄球菌、真菌属等十几种细菌，堪称细菌温床。这其中50%的公用计算机键盘和20%的个人计算机键盘含有金黄色葡萄球菌，而这种细菌一旦进入人体内，则会引发肺炎等严重感染。
计算机键盘不光有细菌，而且还是各种细菌很好的滋生地呢。因为那里面的温度啊、湿度啊等等都给细菌的滋生和繁殖提供了很好的条件。一项美国亚利桑那大学的研究显示，办公室桌面容纳的细菌平均数量超过普通办公室马桶座400多倍。根据微生物学家查尔斯·格巴博士发现，每平方英寸的键盘藏有3295种细菌，相比之下，卫生间的马桶座圈的每平方英寸才有49种细菌。可想而知，隐藏在计算机键盘里的细菌有多少，由此可见，对计算机键盘的杀菌消毒及其重要。
键盘上每个按键间都有缝隙，容易积灰尘，平时表面可以擦擦，可对旮旯缝缝里的污垢细菌往往无能为力，所以，很多人都懒得去管。如果在电脑键盘前吃东西掉进渣子或喝饮料不小心洒进去几滴，时间久了，键盘里的各种污垢会越积越多，要是用按了键盘的手再拿东西吃，细菌则直接进入体内。特别是笔记本电脑，键盘与主体相连，如不注意清洁键盘，还会影响电脑的整体性能。很多人习惯翻过键盘从背面拍拍来清理灰尘，但这样清理根本不彻底，有时用力过大还可能拍坏里面的零件。现在市场上已经出现了电脑键盘专用刷，刷毛又绒又长，软硬适中，造型别致，刷头可深入到键盘缝中，表面和内在同时扫到，价格根据质量的不同，一般在几元到十几元之间，有的电脑专卖店还会随机赠送，日常清洁键盘非常好用。还有一种专门的透明键盘防尘盖，盖在键盘上既美观又防尘。北京市疾病预防控制中心健康教育所李炜主任介绍，还可以用棉签蘸取酒精来擦洗键盘按键，对于难以清洁的缝隙，找一小节细棍，像牙签就可以，缠上适量吸附力强的布或柔软的纸，蘸上酒精，能比较容易地把灰尘擦出来。但是这些处理方式，只能对键盘清洁，并不具有杀菌的效果。
发明内容
针对上述技术问题，结合光触媒在光线照射下，可以杀菌消毒的特性，本发明的目的在于提供一种光触媒键盘贴。
本发明所要解决的技术方案如下：
光触媒键盘贴，是由磨砂表层、光触媒杀菌层、碳纤维涂层、粘合剂层构成的，从外到内依次为磨砂表层、光触媒杀菌层、碳纤维涂层、粘合剂层，在光触媒杀菌层和碳纤维涂层之间具有聚合树脂作为连接层，在碳纤维涂层和粘合剂层之间具有聚合树脂作为连接层，在磨砂表层和光触媒杀菌层之间具有聚合树脂作为连接层。
所述的光触媒键盘贴是长方形结构，在长方形的每个角上具有一个凹槽。
本发明的优点在于：采用磨砂表层，使光触媒键盘贴具有更优良的抗磨、防水、防潮效果；采用光触媒杀菌层，使键盘贴具有杀菌效果，杀菌层中的纳米级二氧化钛遇到光照时，作为光催化剂，可以杀灭细菌，具有除臭去异味的作用；采用碳纤维涂层，使键盘贴具有优良的抗拉抗压效果；采用粘合剂层，使键盘贴与计算机键盘融为一体，且具有凹槽，使键盘贴与计算机键盘具有更好的附着效果。
附图说明
图1为光触媒键盘贴的结构示意图。
图1所示的附图标记如下：磨砂表层1、光触媒杀菌层2、碳纤维涂层3、粘合剂层4、凹槽5。
具体实施方式
光触媒键盘贴，是由磨砂表层1、光触媒杀菌层2、碳纤维涂层3、粘合剂层4构成的，从外到内依次为磨砂表层1、光触媒杀菌层2、碳纤维涂层3、粘合剂层4，在光触媒杀菌层2和碳纤维涂层3之间具有聚合树脂作为连接层，在碳纤维涂层3和粘合剂层4之间具有聚合树脂作为连接层，在磨砂表层1和光触媒杀菌层2之间具有聚合树脂作为连接层。
所述的光触媒键盘贴是长方形结构，在长方形的每个角上具有一个凹槽5。
本发明的优点在于：采用磨砂表层1，使光触媒键盘贴具有更优良的抗磨、防水、防潮效果；采用光触媒杀菌层2，使键盘贴具有杀菌效果，杀菌层中的纳米级二氧化钛遇到光照时，作为光催化剂，可以杀灭细菌，具有除臭去异味的作用；采用碳纤维涂层3，使键盘贴具有优良的抗拉抗压效果；采用粘合剂层4，使键盘贴与计算机键盘融为一体，且具有凹槽5，使键盘贴与计算机键盘具有更好的附着效果。
