Description
【技术领域】
本发明涉及一种抗菌型凝胶退热贴及其制备方法。
【背景技术】
退热贴主要通过凝胶内的水分气化带走人体局部的热量，起到降温退热的作用，而现有的退热贴使用群体主要是婴幼儿或者儿童，但在退热贴的实际使用过程中，退热贴容易从使用者的发热部位处松脱，尤其是婴幼儿，它们不喜欢退热贴的贴肤质感，经常会用手去将退热贴撕下来，在退热贴自行松脱或被撕下来后，水凝胶部裸露在外，非常用以受到环境细菌的污染，若再将沾染了细菌的退热贴重新贴回人体发热部，则这些细菌容易侵害到体质较弱的婴幼儿。
【发明内容】
本发明的目的是为了克服上述问题，我们提供了一种抗菌型凝胶退热贴，其具分子碘成分，可以在退热贴的使用过程中，起到杀菌、抑菌的作用。
为实现上述目的，本发明提供了一种抗菌型凝胶退热贴，包括由上至下设置背衬层、水凝胶层和聚乙烯薄膜覆盖层，其特征在于：所述水凝胶层由下列以重量份数配比的原料制得：高分子物质10-20份、纯化水60-70份、分子碘5-10份、甘油8-13份、冰片3-5份、成型剂0.5-1.5份、交联调节剂0.5-1.5份。
于一个或多个实施例中，所述水凝胶层有下列重量份数配比的原料制得：高分子物质12份、纯化水65份、分子碘8份、甘油9份、冰片3.5份、成型剂1份、交联调节剂1.5份。
于一个或多个实施例中，所述背衬层为无纺布或复合无纺布。
于一个或多个实施例中，所述的交联调节剂为EDTA-2Na。
于一个或多个实施例中，所述成型剂为二氧化钛或高岭土中的一种。
本发明还提供了一种抗菌型凝胶退热贴的制备方法，其通过以下步骤制备：
a.将12份高分子物质、65份纯化水、9份甘油和3.5份冰片放入第一搅拌器中，在常温下以120r/min的转速搅拌20-30分钟；
b.往搅拌器中加入8份分子碘、1份成型剂和1.5份交联调节剂，在40℃的温度下以140r/min的转速搅拌30-40分钟，然后静置20-30分钟后获得水凝胶混合物；
c.将背衬层裁剪成所需形状，将b步骤中得到的水凝胶混合物均匀的涂覆至裁剪后的背衬层上；
d.将聚乙烯薄膜覆盖层裁剪成背衬层的形状，并将裁剪后的聚乙烯薄膜覆盖层覆盖在混合物层上，然后进行固化得出退热贴成品。
于一个或多个实施例中，所述涂覆至背衬层上的水凝胶混合物的厚度为0.5-1.2mm。
本发明同背景技术相比存在的效果是：
由于本发明采用上述的方案，本方案中的退热贴具有抗菌、杀菌的分子碘成分，可以在退热贴使用过程中自动脱落或被撕下后，保护退热贴免受环境细菌的污染。
【附图说明】
图1为本发明抗菌型凝胶退热贴的结构示意图。
