摘　　要：以中国川西地区发现的一种新型矿物资源微晶白云母为原料,以铝酸酯偶联剂F-1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)中制得微晶白云母/PVC复合材料。测试了改性粉体与石蜡体系的黏度及复合材料的力学性能,并采用扫描电子显微镜表征了其微观结构。结果表明,铝酸酯偶联剂F-1能有效改善微晶白云母表面与有机物质的界面结合,并且将经铝酸酯偶联剂F-1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,当铝酸酯偶联剂的用量为1.0%(质量分数,下同)、微晶白云母用量为15%时,微晶白云母/PVC复合材料的力学性能最好。The micro-crystal muscovite is a new kind of minerals found in west Sichuan area. The surface of the micro-crystal muscovite powders was modified by aluminate coupling agent F-1 and was added into plasticized poly （vinyl chloride） （PVC）. The viscosity of the modified micro-crystal muscovite powders/paraffin was tested. The structure and mechanical properties of micro-crystal muscovite/PVC composite were studied by SEM and tesl：er. The results show that aluminate coupling agent F-I can effectively improve the interracial bond strength of micro-crystal muscovite and the organic matter, and the micro-crystal muscovite modified by aluminate coupling agent F-1 can improve mechanical properties of PVC. When aluminate coupling agent F-1 is 1.0 % and the micro-crystal muscovite content is 15 %, the mechanical properties of micro-crystal museovite/PVC composites materials are great.
