摘要
研究了纳米CaCO3用量对PVC微发泡体系的力学性能和泡孔结构的影响。实验表明:随着纳米CaCO3用量的增加,复合体系的弯曲强度先升高后降低,到10份时出现峰值;维卡软化温度和硬度均有所升高,而拉伸强度有所降低;纳米CaCO3用量较少时的泡孔细小,泡孔数目较多且大小分布较均匀。
It studied the effect of the use amount of calcium carbonate on the mechanical properties and cell structure of PVC composites . The results showed that with the increase of use amount of CaCO3, the flexural strength first increases until to peak value (10phr CaCO3 ), and then decreases, both vicat softening point and hardness increase, but tensile strength decreases; when the use amount of calcium carbonate is less, the cells are small, but more in number, and they have uniform distribution in size.
