摘要:: 利用熔融共混的方法,考察了K树脂的质量分数在10％～50％时对聚苯乙烯(PS)/K树脂合金材料光学和力学性能的影响,并且用扫描电镜分析了冲击样条断面的表面形貌.结果表明,在K树脂的质量分数从10％变化到50％过程中,PS/K树脂合金的雾度可由24.6％降低为11％,而透光率与纯PS相差无几,仅仅从86.5％变化为85.6％,说明PS与K树脂的光学匹配性较好.力学性能测试结果扣扫描电镜分析均表明,随着K树脂在合金中所占的质量分数增加,合金材料的冲击韧性和拉伸时所产生的断裂伸长率均有所增大,冲击韧性从1.93 kJ/m2增大到4.65 kJ/m2,断裂伸长率从1.5％增大到14.5％,表现出明显的塑性变形形貌.

Abstract:: In thispaper，the effect ofmass fraction of K·Resin with the range from 10％to50％onthe optical andmechanical properties of polystyrene(PS)／K—Resin wasstudied by melting mixing method，and the surface morphology of the cross-section of impact sampleswere analyzed withSEM．The results showthatwith the increase of K-Resin’S mass fraction from 10％to 50％，the haze of PS／K-Resin alloy can be decreased to 11％from24．6％while the transmittance is almost the same as pure PS．only change from 86．5％to 85．6％．indicating that the optical match of PS and K·Resin is good．The results of mechanical properties and SEManalysis show that with the increase of K·Resin’S mass fraction in the alloy，the impacttoughness of the alloy material and the elongation at breakgenerated by tension both increase，the impact toughnesscan be increased to 4．65 kJ／m2 from 1．93 kJ／m2 andthe elongation at break generated by tensioncan be increased to 14．5％from 1．5％．showinganobvious plastic deformation morphology．
