| 摘 要： | 在一定温度条件下,用氨基硅油对苎麻纤维进行表面改性处理.利用红外光谱分析(IR)、接触角测试、X射线衍射分析(XRD)、热重分析(TG)等方法对改性前后苎麻纤维的性能进行分析.结果表明,经氨基硅油改性的苎麻纤维表面成功包覆了有机硅分子,且表面羟基数量减少,吸水性较未改性的苎麻纤维下降,与聚丙烯相容性提高;改性后,苎麻纤维的结晶度提高了15%;在230℃以前,未改性的苎麻纤维质量损耗为5%,而改性后苎麻纤维基本上没有分解,改性后苎麻纤维的耐热性能有了较大的提高。

| Abstract: | Ramie fiber was treated with amino silicone oil.The properties of ramie fiber were investigated with IR,contact angle test,XRD,and TG.The results have shown that some silicone molecules were coated on the surface of the modified ramie fiber,and it reduced the number of hydroxyl groups on the ramie surface.The crystallinity of ramie fiber was increased by 15%,and the water absorption of the modified ramie fiber was decreased,inducing a better compatibility between ramie fiber and polypropylene.In addition,the weight of the unmodified fiber had a loss of 5% before 230 ℃,while the modified ramie fiber had no decomposition virtually,so that the heat resistance of the modified ramie fiber has been greatly improved. |
