高光泽耐冲击填充改性聚丙烯及制法和应用
摘要：
本发明公开了一种高光泽耐冲击填充改性聚丙烯及制法和应用。采用本发明的方法制备的聚丙烯材料的各项性能指标均达到或超过预定的要求，解决了高光泽聚丙烯材料耐冲击韧性不足及尺寸稳定性差等缺点，满足了家电行业对材料的外观、性能及工艺特性的要求。材料在23℃下的弯曲模量达1000MPa以上时，悬臂梁缺口冲击强度仍可达6KJ/m2以上，同时仍具有很高的光泽度，光泽度≥60％；综合其他指标已经充分达到甚至超过家电行业对高光泽产品综合性能的要求。
摘要（英）：

This invention discloses a method for preparing high-luster impact-resistant filler-modified polypropylene and its application. The properties of the polypropylene material prepared by this method can meet or even outperform the preset requirements. The high-luster polypropylene material has such advantages as high impact toughness, and high dimensional stability, and can meet the requirements ofappearance, performance and process characteristics of home appliance industry. The bending modulus of the polypropylene material at 23 deg.C is higher than 1000 MPa, the impact strength of notched izod is higher than 6 kJ/m<2>, and the luster is greater than or equal to 60%.
