Description

一种纳米金刚石口罩及纳米金刚石杀菌纤维布的制备方法
技术领域
本发明属于医疗防护用品技术领域，具体涉及一种纳米金刚石口罩及纳米金刚石杀菌纤维布的制备方法。
背景技术
现有的医用口罩之所以能够阻挡细菌和病毒，主要是依靠口罩的过滤层，过滤层的材料是经高温熔喷产生的超细纤维，可以有效阻挡飞沫和微尘，可以隔绝细菌和病毒，起到保护的效果。其原理是熔喷无纺布通过高压电机放电等步骤，使其带电荷，形成一种静电效应，对颗粒物进行拦截。但是，在使用过程中，呼吸所带来的湿气的变化，其过滤效率会发生迅速下降，需要每四个小时更换一次。使用寿命短，更换频繁。
研究表明，纳米金刚石具有较高的吸附能力和较强杀菌特性，可在短时间内杀死致病的病毒、微生物和细菌，纳米金刚石具有非常高的活性，对细菌和病毒有强烈地吸收能力，是超活性的吸附剂。利用纳米金刚石的特性制作口罩还未见报道。
发明内容
针对现有技术中的不足之处，本发明提供一种纳米金刚石口罩及纳米金刚石杀菌纤维布的制备方法。
为了达到上述目的，本发明技术方案如下：
一种纳米金刚石口罩，包括由外至内一层过滤层和一层杀菌层，所述过滤层采用纳米纤维布料，所述杀菌层采用纳米金刚石杀菌纤维布。
进一步的，所述纳米金刚石所在的一侧面位于朝向过滤层。
一种纳米金刚石杀菌纤维布的制备方法，将纳米金刚石与粘结剂混合均匀，将纳米纤维材料通过混合体，通过常温或者一定温度进行快速固化，让纳米金刚石附着在纤维表面制成的。
另一种纳米金刚石杀菌纤维布的制备方法，将纳米金刚石、纳米纤维材料与粘结材料混合体，利用熔喷设备制成附着纳米金刚石的超细纤维。
还有一种纳米金刚石杀菌纤维布的制备方法，将纳米金刚石和粘结材料，利用专用设备在特定温度下，通过高压喷涂方式，使其附着在纳米纤维上，从而制成附着纳米金刚石的超细纤维。
有益效果：本发明引入纳米金刚石作为口罩产品的吸附杀菌材料，采用涂覆粘结技术将纳米金刚石附着在纤维表面，从而提高口罩隔离吸附病毒的能力；增强口罩的杀菌能力增加口罩的使用周期，降低医护人员受感染的风险。

具体实施方式
以下参照具体的实施例来说明本发明。本领域技术人员能够理解，这些实施例仅用于说明本发明，其不以任何方式限制本发明的范围。
一种纳米金刚石口罩，如图1所示，包括由外至内一层过滤层1和一层杀菌层2，过滤层采用纳米纤维布料，杀菌层采用纳米金刚石杀菌纤维布，纳米金刚石杀菌纤维布为纳米纤维材料的表面附有纳米金刚石层3，纳米金刚石层3位于朝向过滤层1的一侧。
其中，纳米金刚石杀菌纤维布可以通过以下三种制备方法制得：
方法一是通过将纳米金刚石与粘结剂混合均匀，将纳米纤维材料通过混合体，通过常温或者一定温度（80~120℃）进行快速固化，让纳米金刚石附着在纤维表面制成的；
方法二是将纳米金刚石、纳米纤维材料与粘结材料混合体，利用熔喷设备（243-268℃(469-514℉)）制成附着纳米金刚石的超细纤维；
方法三是将纳米金刚石和粘结材料，利用专用设备在特定温度下，通过高压喷涂方式，使其附着在纳米纤维上，从而制成附着纳米金刚石的超细纤维。
