摘要：采用直接混合法制得聚丙烯/滑石粉(PP/Talc)体系和聚丙烯/成核剂磷酸酯钠盐/滑石粉(PP/NA-40/Talc)体系,研究了Talc的添加量对两种复合体系的力学性能、耐热性能、流动性能以及结晶温度的影响,从动力学角度解释了力学性能提升的原因。结果表明,在PP中加入0.2%(质量分数,下同)的NA-40和10%的Talc时,使PP弯曲模量达到2 316.0MPa,热变形温度达到120.0℃,结晶温度达到132.9℃,流动性能基本不变,从而满足高刚、耐热PP的使用需求。
The polypropylene(PP)/Talc compounding system and polypropylene/sodium phosphate nucleating agent(NA-40)/Talc compounding system were prepared by a melt mixing method,and the effect of Talc content on the mechanical properties,heat resistance,flow properties and crystallization temperature of two compound systems was investigated.The reasons for improvement in mechanical properties of compounding systems were analyzed by a dynamic method.The results indicated that the compounds achieved the flexural modulus of 2 316 MPa,a heat distortion temperature of 120℃and a crystallization temperature of 132.9℃when 0.2 wt%of NA-40 and 10 wt%of Talc were added into PP.Meanwhile,the flow properties of the compounds seemed not to change.These results meetthe requirements of PP for high rigidity and high heat-resistance.
