Description

一种水溶性可降解马桶坐垫及其制备方法
技术领域
本发明涉及卫生用品技术领域，具体涉及一种水溶性可降解马桶坐垫及其制备方法。
背景技术
目前，公共场所的卫生间大都采用了坐便器设施。这种设施虽然文明方便，但在使用中易产生一些疾病的交叉感染或污染，给使用者带来烦恼，让人不敢正常使用公厕坐便器。
申请号为CN200720008590.8的中国发明专利公开一种采用多层U形薄片层叠压制而成的卫生马桶坐垫，马桶坐垫底面这一层涂有不干胶并有防胶纸层，底面设有用以固定的吸盘。使用者撕掉最上面的一层薄片即可保证使用全新的一次性卫生马桶坐垫。
但该技术方案中薄片材质不可降解，对环境不友好；使用后需要专门的收集袋收集由管理人员专门处理，费人费力。同时由于这种多层马桶坐垫直接置放于坐圈上，容易受到污染，使用者容易一次撕掉多层薄片，造成浪费。
申请号为201720878642.0的中国发明专利公开的一种水溶性可降解马桶坐垫及其固定装置，其中卫生垫由水溶性可降解材料制成。而这种水溶性可降解材料的卫生垫直接粘于马桶坐圈上与人体接触，使用过程中容易与人体粘贴，造成人体不适感，而且会给马桶坐圈留下粘痕，不利于后序使用。并且这种水溶性可降解材料的溶解速度较慢，使用频繁则马桶有堵塞的危险。
发明内容
为解决现有技术中存在的不足，本发明的目的在于，提供一种柔韧、舒适、无菌的水溶性可降解马桶坐垫，此马桶坐垫干净、卫生、舒适度高，使用便捷，使用后直接进入坐便器随排泄物一起冲入下水道分解溶化，减少了环境污染。

所述KJ-200是KJ-200胶水稠定剂。
本发明还提供上述水溶性可降解马桶坐垫的制备方法，包括以下步骤；
步骤1，将水溶膜覆于覆膜机上，将水性胶粘剂通过涂胶辊均匀涂到水溶膜上表面上，用加热辊将医用无菌纸与所述水溶膜热压覆合成一体；
步骤2，将所述水溶膜翻面，按步骤1的操作在水溶膜下表面上将所述医用无菌纸与所述水溶膜热压覆合成一体；
步骤3，对上、下表面均与医用无菌纸热压覆合的所述水溶膜通过加热压纹后裁切成形。
优选地，所述加热辊的温度为110℃。
优选地，所述水溶膜的制备方法为：先将聚乙烯醇加适量水溶解，然后水浴加热至70-80℃，再加入增强剂、增塑剂、乳化剂和脱模剂，然后搅拌均匀，静置2小时后消泡，24小时后采用钢带流延法烘干成膜。
所述聚乙烯醇类水性胶粘剂由制备原料通过加热混合搅拌而成。
