Description

一种柔性聚氨酯合成胶及其制备方法
技术领域
本发明涉及一种柔性聚氨酯合成胶及其制备方法，还涉及该合成胶作为高回弹性缠绕固结带粘接剂的应用，属于高分子材料技术领域。
背景技术
公知医药领域常利用反应釜合成目标产品。反应釜夹层可通上不同的冷热源（冷冻液，热水或热油）做循环加热或冷却反应。它的工作原理是：通过反应釜夹层，注入一定温度的热溶媒体或冷却媒体，对反应釜内的物料进行加热或制冷。
通常在医学器材方面，手术后恢复期内，医生往往采用绷带包扎等方法对病人骨折部位进行体位固定。由于绷带包扎要达到一定厚度才能确保较好的固定或止血效果，但其扰曲弹性不够，病人受损伤的软组织不能得到有效锻炼，从而延长骨折或骨科矫形病员的康复期，提高病人的康复成本。因此，实现病人骨折部位包扎的密封性和高回弹性不仅可以保护病人骨折部位，使其在短期内康复，还可以降低病人的康复成本。在工程施工方面，常出现电缆、管道破损问题，轻则影响人们的生产生活，严重的还会引发事故。快速修复破损物件不仅可以防范事故风险，还可以延长物件使用寿命，节约成本。这些都对高回弹性缠绕固结带粘接剂的研发和产业化提出了要求。
发明内容
本发明的目的在于提供一种柔性聚氨酯合成胶。所述合成胶用于固结带上的粘接剂。
本发明的另一目的提供一种柔性聚氨酯合成胶的制备方法。
