【摘要】 本文综合分析了冲击、弯曲、剪切应力—应变试验,DSC、X 射线衍射和粘弹性能测定,以及用 Brabender 塑化仪测出的塑化扭矩等实验结果,证明了采用丙烯酸酯类单体（或再加少量 DOP）处理后的 CaCO₃填充聚丙烯,使单体在加工过程中聚合,所得材料具有优良的机械、热和加工性能等方面的综合性能。聚丙烯酸酯改性处理剂同时兼具偶联剂、粘胶剂、增韧剂和加工助剂的作用。本文也讨论了工艺的影响更多还原

【Abstract】 Comprehensively analyzing the results of impact,bending,and shearstress-strain tests,DSC,X-ray diffraction and dynamic viscoelasticity measu-rements,as well as the plastification torques measured by Brabender plasticor-der,it has proved that PP filled with acrylate monomer-treated CaCO₃ hasgood combination of mechanical,thermal and processing properties,due to theacrylate monomer is polymerized in thec course of processing and polymerizedacrylate modifier also acts as coupling agent binding agent,toughenss modi-fier and processing aid.The influences of technology also have been discu-ssed.更多还原
