Description

一种N-异冰片基丙烯酰胺单体、阻燃单体、阻燃性材料及阻燃 性材料的制备方法
技术领域
本发明涉及一种N-异冰片基丙烯酰胺单体、阻燃单体、阻燃性材料及阻燃性材料的制备方法,属于无卤阻燃剂领域。
背景技术
近年来,阻燃材料已经成为工业和研究领域中的主要问题之一。传统上,多采用有机卤化物制备阻燃材料,然而卤化物中的氯、溴元素会在燃烧过程中生成有毒和腐蚀性的烟雾。因此,需要寻找环保的无卤阻燃剂来保护人类健康和生态系统。常见的无卤阻燃剂主要包括硼原子、含磷化合物和有机硅衍生物等,其中有机硅被认为是“环保”添加剂,因为与现有材料相比,它的使用可以减少对环境的有害影响。
中国专利文献CN108359174A公开了一种低气味低溴阻燃聚丙烯复合物及其制备方法,采用聚丙烯(PP)62%-90.6%、复合阻燃剂3%-15%、增韧剂5%-15%、除味剂1%-5%、抗氧剂0.1%-1.5%、其他加工助剂0.3%-1.5%,阻燃性得到提高,但是由于使用卤元素,仍然含有毒性,对人体有害。
现有的阻燃材料仍然存在阻燃性能和环保要求不能很好地兼顾的问题,且所用原料多限于石化产品。

上述用N-三甲氧基硅丙基-N-异冰片基丙烯酰胺(NPSBAM)作为阻燃单体,与N-异丙基丙烯酰胺(NIPAM)无规共聚制备阻燃型材料。阻燃单体来源于松节油,是一种天然的可再生的生物质材料,无毒无害,申请人经研究发现,松节油衍生物的氮元素,可以与有机硅协同阻燃,具有良好的应用前景。
