Description

一种新型水胶体
技术领域
本发明涉具体涉及一种新型水胶体。
背景技术
水胶体产品在医用器械中是吸收伤口渗液的产品，其吸收液体量和吸收速度直接影响到产品使用性能。同时，胶体的粘性也是一个重要的指标，既要不失粘性，又同时要对吸液的速度和吸液量进行控制，既有的配方和技术还未能有效达到目的。存在如下问题：1.现有配方是吸水材料（CMC-Na）被热熔胶包裹，影响了吸水材料的正常发挥。2.增加吸水材料量不仅增加成本，而且也对粘性有较大的影响。3.吸水材料有轻微的酸性气味。
发明内容
为了解决上述问题，本发明提供了一种高强度亚克力板材：
一种新型水胶体，按重量份计包括下述组分：
20-30%线性高分子离子型纤维素醚、1-10%丙烯酸嵌段共聚物、5-20%环糊精、EVA热熔胶至100%。
优选的，所述线性高分子离子型纤维素醚为羧甲基纤维素钠。
优选的，所述丙烯酸嵌段共聚物包括至少一个聚丙烯酸C1-C10烷基酯嵌段和/或聚甲基丙烯酸C1-C10烷基酯嵌段。
优选的，丙烯酸嵌段共聚物为聚(甲基丙烯酸甲酯-丙烯酸正丁酯-甲基丙烯酸甲酯)三嵌段共聚物，聚(甲基丙烯酸甲酯-丙烯酸正丁酯)两嵌段共聚物，或所述三嵌段共聚物和两嵌段共聚物的混合物。
本发明具有如下有益效果：用环糊精的环形分子结构形成可通过水分子通过的通道。
具体实施方式
下面结合实施例对本发明进行进一步说明。
实施例1：一种新型水胶体，按重量份计包括下述组分：20%羧甲基纤维素钠、5%聚(甲基丙烯酸甲酯-丙烯酸正丁酯-甲基丙烯酸甲酯)三嵌段共聚物、5%环糊精、EVA热熔胶至100%。
实施例2：一种新型水胶体，按重量份计包括下述组分：25%羧甲基纤维素钠、1%聚(甲基丙烯酸甲酯-丙烯酸正丁酯)两嵌段共聚物、10%环糊精、EVA热熔胶至100%。
实施例3：一种新型水胶体，按重量份计包括下述组分：30%羧甲基纤维素钠、10%聚(甲基丙烯酸甲酯-丙烯酸正丁酯-甲基丙烯酸甲酯)三嵌段共聚物和聚(甲基丙烯酸甲酯-丙烯酸正丁酯)两嵌段共聚物的按1:2比例混合的混合物、20%环糊精、EVA热熔胶至100%。用环形分子结构新料且环形材料可通过水分子。
显然，本发明的上述实施例仅仅是为了说明本发明所作的举例，而并非对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其他不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷例。而这些属于本发明的实质精神所引申出的显而易见的变化或变动仍属于本发明的保护范围。
