摘要
针对中国川西地区发现的一种新型矿物资源微晶白云母,以硅烷偶联剂KH-550为改性剂,对微晶白云母进行改性研究,并将表面改性后的微晶白云母加入聚氯乙烯(PVC)材料中制得微晶白云母/PVC复合材料。测试改性粉体与石蜡体系的粘度及复合材料的力学性能,并采用扫描电子显微镜测试研究其微观结构。结果表明:硅烷偶联剂KH-550能有效改善微晶白云母表面与有机物质的界面结合,并且将经硅烷偶联剂KH-550改性的微晶白云母加入PVC基体中能提高微晶白云母/PVC复合材料的力学性能,当硅烷偶联剂的用量为1.2%、微晶白云母用量为35%时,微晶白云母/PVC复合材料的综合力学性能最好。
The micro-crystal muscovite is a new kind of mineral found in west Sichuan area.The surface of the micro-crystal muscovite powders were modified by silane coupling agent KH-550 and added into plasticized poly(vinyl chloride)(PVC).While the modified micro-crystal muscovite powders were studied by viscosity,and the structure and properties of such micro-crystal muscovite/PVC were tested.
