一种抗菌基材及其制备方法
技术领域
本发明涉及一种抗菌基材及其制备方法。
背景技术
以往的抗菌涂层和抗菌产品，主要以金属氧化物，例如带银离子，钛离子等的金属氧化物，通过破除细菌的细胞壁，使细菌无法繁衍和存活。但游离在使用产品表面的银离子和钛离子始终对人是有一定的伤害。毕竟涂层的缓慢释放量并没有一个标准，释放量大的时候，虽然能达到杀菌，抗菌的效果，但释放量是否会伤害人体，使用者难以判断。再者使用金属氧化物的抗菌涂层其加工在各种基材上的能力各不一样，要对每一种金属氧化物采取特定的工艺，加工到基材上。
发明内容

作为优选的技术方案，粘结层采用二氧化硅纳米颗粒、水、甲醛、甲醇、乙醇、异丙醇、氢氧化钠、硫酸、硝酸、盐酸、流平剂、稳定剂、助剂混合制备而成，通过粘结层将抗菌涂层固定在基材的表面。
一种抗菌基材，具体步骤如下：
步骤一、选用任意一种需要做抗菌处理的基材，然后将粘结层以任意一种方式设置在基材上；
步骤二、粘结层的上端可根据实际使用环境设置一层功能性涂层或者不设置；
步骤三、在二氧化硅纳米颗粒上端或者在功能性涂层上端设置一层非金属氧化物制成的抗菌涂层；
步骤四、对涂抹完成后的基材进行固化；
步骤五、步骤四中，基材的固化温度在80-300度，固化的时间在30-180分钟。
本发明的有益效果是：选取非金属/及非金属氧化物的抗菌剂，二氧化硅纳米颗粒作为粘合剂；加工工艺简单，可调节，基底可为陶瓷、塑料等材料，基底材料多样化，二氧化硅纳米颗粒对陶瓷、塑料等基底有很好的粘结作用。
