Description

一种聚氨酯泡沫减震材料及其制备方法
技术领域
本发明涉及减震材料领域，特别涉及一种聚氨酯泡沫减震材料及其制备方法。
背景技术
聚氨酯泡沫有缓冲的功能，常用于沙发家具、枕头、坐垫、玩具、服装和隔音内衬。传统的聚氨酯泡沫产品减震功能，主要利用聚氨酯泡沫多孔性可压缩性实现的。当这种材料应用于人体防护或精密仪器防护上主要存在的缺点是减震性能有限，在受到剧烈冲击时，普通的防护材料并不能完全地将冲击能量有效地耗散掉，依然会有很强的冲击力作用在人体或设备上，会导致人体受伤或设备损坏。这些问题产生，对材料性能有了更高的要求。
目前所采用的大部分冲击减震***为独立的发泡的聚氨酯、EVA、橡胶体系。体系简单，减震缓冲性能一般，应用于高端缓冲领域时，防护效果有限。现有较为成熟的技术，为英国的D3O产品，基体采用的是聚氨酯，使用温度范围为-10℃～+80℃，用于人体防护，不能使用于温度较高的环境，如发动机、长期振动生热部位。目前的专利有关于剪切增稠凝胶的，也有关于凝胶与聚氨酯弹性泡沫复合的，主要是解决凝胶在聚合物基体中的分散问题，有的是将吸能凝胶分散于有机溶剂(如异丙醇)或者羟基硅油中，这两种方法存在的缺点是工艺复杂，需要在反应过程中去除溶剂同时限制吸能填料加入量，加入相容剂促进吸能填料更好在聚氨酯基体中分散，聚氨酯泡沫体复合材料的制备技术很少，同时聚氨酯发泡工艺成熟。
发明内容
基于此，有必要提供一种工艺简单，减震吸能能力强的聚氨酯泡沫减震材料及其制备方法。

在一些实施例中，在将所述混合物与改性的MDI混合，再经发泡、熟化得到聚氨酯泡沫减震材料的步骤中，具体为：在将所述混合物与改性的MDI混合，置于模具中发泡，并保压时间4～15min，取出后常温熟化12～72h得到聚氨酯泡沫减震材料，所述模具的温度为45～80℃。
另外本申请还提供了上述聚氨酯泡沫减震材料的制备方法制备得到的聚氨酯泡沫减震材料。
本发明提供的聚氨酯泡沫减震材料的制备方法，将剪切增稠凝胶、相容剂、聚氨酯A料加热混合形成混合物，将所述混合物与改性的MDI混合，再经发泡、熟化得到聚氨酯泡沫减震材料，本发明提供的聚氨酯泡沫减震材料的制备方法，以聚氨酯泡沫作为基体材料，与剪切增稠凝胶进行复合的技术方案，由于剪切增稠凝胶本身粘度很大，很难直接在聚氨酯A料中分散，在引入剪切增稠凝胶的过程中，加入相容剂，简化了生产工艺，降低了副反应发生概率，产品生产工艺容易控制。
