纳米级CaCO3对聚氯乙烯/丙烯酸酯橡胶的增韧改性
Study on toughening of PVC/ACR by the way of blending with nanometer CaCO3
【摘要】 采用丙烯酸酯橡胶 (ACR)、纳米级CaCO3 对聚氯乙烯 (PVC)进行增韧改性 ,并对该体系的断裂面形貌和加工流变性能进行了研究。结果表明 ,纳米级CaCO3 能进一步改善PVC/ACR共混合金的冲击性能 ;其加工流变性能不仅没有降低 ,而且略有提高
【Abstract】 The improvement of impact strength of polyvinyl chloride(PVC) by the way of blending with acylic rubber(ACR) and nanometer CaCO 3 was discussed. The fractured surface and processing rheology property were also analysed. Results show that the nanometer CaCO 3 can further improve the impact strength of PVC/ACR blend and the rheology property of the system.
