Abstract

本发明属于一种医药用软质聚氨酯泡沫塑料的 制备工艺，它是将现有的聚氨酯泡沫塑料，先经稀碱 水溶液，后经稀酸水溶液煮洗后，再用蒸馏水洗净，经 除去残留杂质，最后榨干，用远红外真空干燥制成，其 工艺方法简单，价格便宜，清除了产品有毒物质的残 留部分，可直接做医用敷料和药物载体，具有柔软性 和弹性，对药物具有优良的缓释性。

Description

本发明属于医药用软质聚氨酯泡沫塑料的制备工艺。是对现有聚氨酯泡沫的一种改进。
目前，市场上销售的软质聚氨酯泡沫塑料具有比现有药用海棉剂不可比拟的优良的弹性，柔软性和多孔性，及使药物缓释的性能，是很适合做药物载体的。但是制备本品所需的原料甲苯异氰酸酯和助剂三乙撑二胺等，可在成品中残留，给人体造成危害，故不能直接做医药用。
本发明的目的在于提供一种：根据这些物质具有的挥发性，水溶性或在酸碱催化下可分解的特性，采用酸碱水溶液煮洗的工艺，将其残留部分除掉，使产品符合医药用要求。
本发明的目的是这样实现的，其工艺流程如下：将现有的聚氨酯泡沫塑料冲剪成型→稀碱液煮洗→榨干→去离子水洗除碱→榨干→稀酸液煮洗榨干→蒸馏水洗→榨干→远经外真空干燥即可可直接做医用敷料和药物载体用。
本发明医用软质聚氨酯泡沫塑料的制备工艺：方法简单，价格便宜，清除了产品有毒物质的残留部分，可直接做医用敷料和药物载体用，具有柔软性和弹性，对药物具有优良的缓释性。
下面是本发明的最佳实施例：以阴道用海绵制剂载体的制备工艺为例，取软质聚氨酯泡沫塑料，用冲孔机冲成长60mm，○16mm的园柱体，采用0.5%的氢氧化钠水溶液煮洗→榨干→去离子水洗除碱→榨干→1%的醋酸水溶液煮洗→榨干→蒸馏水洗净→榨干→远红外真空干燥→质检合格即可。
