摘要/Abstract

摘要： 采用共沉淀法合成了ZnAl-LDHs，并以油酸钠为表面改性剂，对其进行湿法表面改性制备油酸钠改性的ZnAl-LDHs（O-ZnAl-LDHs）。通过X射线衍射（XRD）、傅里叶变换红外光谱（FTIR）、扫描电镜（FESEM）及热重分析（TG）对改性前后的ZnAl-LDHs进行了表征。将改性前后的ZnAl-LDHs分别添加至ABS中，制备ZnAl-LDHs/ABS复合材料，通过阻燃和力学性能测试考察了改性前后ZnAl-LDHs的添加量对复合材料性能的影响。结果表明：当添加量为10%～50%时，改性前后的ZnAl-LDHs均能使ABS复合材料极限氧指数（LOI）提高，当添加量为40%时，改性后的ZnAl-LDHs氧指数较未改性的ZnAl-LDHs有着明显提升且满足UL-94垂直燃烧测试的V-1级别要求；当改性后的ZnAl-LDHs添加量为50%时，LOI可达28.2%，且满足UL-94垂直燃烧测试的V-0级别要求；而力学性能相对于同等添加量下未改性的复合材料均有不同程度的提高。

Abstract: ZnAl-LDHs was synthesized by coprecipitation, and then modified using sodium oleate as the surface modifier to prepare the sodium oleate ZnAl-LDHs(O-ZnAl-LDHs). The ZnAl-LDHs and O-ZnAl-LDHs samples were characterized by XRD, FTIR, FESEM and TG. Adding ZnAl-LDHs and O-ZnAl-LDHs into ABS to prepare ABS composites, the effects of the addition of LDHs on the retardant and mechanical properties of the composites were investigated. The experimental results showed that:when the addition was 10%~50%, both the ZnAl-LDHs and O-ZnAl-LDHs can improve the limit oxygen index (LOI) of the ABS composites, when the addition of O-ZnAl-LDHs was 40%, the modified ZnAl-LDHs oxygen index improved significantly compared with the unmodified ZnAl-LDHs, and met the requirements of V-1 level in the UL-94 vertical combustion test; when the addition of O-ZnAl-LDHs was 50%, the LOI can reach 28.2%, and met the requirements of V-0 level in the UL-94 vertical combustion test; while the mechanical properties of O-ZnAl-LDHs/ABS composite improved certainly compared to the ZnAl-LDHs/ABS composite at the same addition.
