摘要:
采用乙烯基硅烷在氢氧化镁晶须(MH)表面引入乙烯基后与苯乙烯进行原位聚合,制备了苯乙烯原位聚合改性氢氧化镁(MMH) 晶须.将改性前后的MH分别与高抗冲聚苯乙烯(HIPS)熔融复合制备了不同的HIPS/MH复合材料,采用扫描电镜和毛细管流变仪研究了复合材料的形态结构和流变性能.结果表明HIPS/MH复合材料为剪切变稀的非牛顿流体,其表观黏度、非牛顿指数大于纯HIPS.随着填充量的增加,HIPS/MH复合材料表观黏度增大,非牛顿指数总体上也表现出增大的趋势.苯乙烯原位聚合改性MH晶须能改善了其与HIPS的界面粘接,降低HIPS/MH复合材料的粘流活化能.
Abstract:
The magnesium hydroxide (MH) whiskers were modified with 3(trimethoxysilyl) propyl methacrylate followed by in situ copolymerization of styrene. The high impact polystyrene (HIPS)/MH composites were prepared by melt compounding of HIPS with blank MH whiskers and modified MH whiskers (MMH), respectively. Their morphological structure and rheological properties were characterized by scanning electron microscopy and capillary rheometer. The results show that the HIPS/MH composite is a shearthinning nonNewtonian, and its apparent viscosity and nonNewtonian index (n) are bigger than those of the HIPS melt. The apparent viscosity and n of HIPS/MH composites increase,with the increasing of MH loading. The PS encapsulated on MH whiskers surface enhances the interface adhesion between inorganic particles and HIPS matrix, and obviously reduces the flow activation energy (ΔE) of the HIPS/MH composite.
