Abstract

热溶型丙烯酸酯医用压敏胶,选用60-90%丙烯酸丁酯,15-25%甲基丙烯酸丁酯、3-5%丙烯酸三种单体在具有引发剂的条件下聚合反应,制得透明粘状液体;本发明涂布在棉布、无纺布或桑皮纸上制成医用胶带,与现在常用的氧化锌胶带相比具有粘性适中,贴附舒适,对皮肤无刺激等特点。

Description

热溶型丙烯酸酯医用压敏胶
本发明属于粘合剂类,具体地涉及一种涂布在特定基材上作为胶带使用约医用压敏胶。
目前,医疗上所使用的胶带是人们十分熟悉的氧化锌胶带,由于这种胶带上的压敏胶是以橡胶为骨架材料制成,含有松香类、汽油等有害物质,对伤口及皮肤有很强的刺激性。同时,生产这种压敏胶对环境污染严重。近十年来,卫生部、国家医药总局、军委后勤部曾先后组织科研部门攻关,但使用起来效果总不令人满意。
本发明所要提供的就是对皮肤无刺激、贴附舒适、粘性适中、生产过程中无污染的医用压敏胶。
本发明主要选用下述原料及含量(重量%):60-90%丙烯酸丁酯(单体Ⅰ)、15-25%甲基丙烯酸丁酯(单体Ⅱ)、3-5%丙烯酸(单体Ⅲ)、0.1-0.4%的过氧甲酸叔丁酯、0.6-0.9%的十二烷基硫酸钠、1.0-1.5%的醋酸锌或酸酸亚铁。
上述丙烯酸丁酯、甲基丙烯酸丁酯、丙烯酸三种单体混合后,加入到溶有引发剂的甲苯溶液中,置于反应釜中于100℃-125℃反应6-7小时,聚合得透明粘状液体,再加入酸酸锌或醋酸亚铁、十二烷基硫酸钠,蒸馏去除甲苯,趁热放料,即为热溶胶产品。
本产品常温下为固体,加热后呈流体状,降温即干燥,100%含固量,不含溶剂,生产安全,无污染,尤其将其涂布在基材上,粘贴十分舒适,无副作用,透气防水,它的问世,将实现我国以高分子材料取代橡胶弹性体做为医用粘胶剂原料零的突破。
上述粘胶剂既适合在棉布上涂布,又适合在无纺布、桑皮纸上涂布,目前以在桑皮纸上涂布效果最佳。
下面详述本发明的实施例:
实施例1:取丙烯酸丁酯60G,甲基丙烯酸丁酯15G,丙烯酸3.0G,混合,取过氧甲酸叔丁酯0.1G溶于80G甲苯中,再混入上述三种单体,置于反应釜中于110-115℃反应6-7小时,聚合得透明粘状液体,再加入0.6G十二烷基硫酸钠,1.0G醋酸锌或醋酸亚铁,蒸馏去净甲苯,趁热放料,即得热溶胶产品。
实施例2:取丙烯酸丁酯75G,甲基丙烯酸丁酯20G,丙烯酸4.0G,混合,取过氧甲酸叔丁酯0.25G溶于100G甲苯中,再混入上述三种单体,置于反应釜中于110-115℃反应6-7小时,聚合得透明粘状液体,再加入0.75G十二烷基硫酸钠,1.25G醋酸锌或醋酸亚铁,蒸馏去净甲苯,趁热放料,即得热溶胶产品。
实施例3:取丙烯酸丁酯90G,甲基丙烯酸丁酯25G,丙烯酸5.0G,混合,取过氧甲酸叔丁酯0.4G溶于110G甲苯中,再混入上述三种单体,置于反应釜中于110-125℃反应6-7小时,聚合得透明粘状液体,再加入0.9G十二烷基硫酸钠,1.5G醋酸锌或醋酸亚铁,蒸馏去净甲苯,趁热放料,即得热溶胶产品。
