摘要：采用实验室自制的密炼机制备了聚丙烯(PP)/聚碳酸酯(PC)共混材料,通过形貌分析、流变测试、拉伸试验、缺口冲击强度测试、光学测试等对复合材料的微观形貌、流变性能、力学性能和光学性能进行了表征,并研究了2-(2’-羟基-5’-甲基苯基)苯并三唑(UV-P)填充PP/PC复合材料的抗紫外性能。结果表明,在透光性和雾度的耦合性能方面,PC相含量存在一个阈值;在抗紫外性能方面,UV-P的添加量存在一个阈值。当PC含量为3%(质量分数,下同)时,所制备的共混物的拉伸强度为30.40 MPa,抗冲击强度在44.85 J/m;在添加0.1份UV-P之后,紫外光区域的平均透过率为1.04%,此时的透光率为83.39%,雾度为93.65%,制备的复合材料具有良好的散射效果,且对紫外光线有强烈的吸收作用。
In this paper,PP/PC blends were prepared by using a laboratory?made internal mixer,and their microstruc?ture,rheological properties,mechanical properties,and optical properties were characterized by topography analysis,rheological test,tensile test,notch impact strength test,and optical test.The UV shielding effect of UV?P filled PP/PC compounds was studied.The results indicated that there was a threshold of dispersed phase content in the coupling per?formance of light transmittance and haze.There was a threshold for the addition amount of UV?P according to the UV shielding effect.The tensile and impact strength of the as?prepared blends reached 30.40 MPa and 44.85 J/m,respec?tive,at a PC content of 3 wt%.When 0.1 phr UV?P was incorporated,the blends presented an average transmittivity of 1.04%in the UV region,a transmittance of 83.39%,and a haze of 93.65%.The blends developed in this work ex?hibited a good scattering effect and strong absorption of ultraviolet light.
