摘要
本文将线型聚丙烯辐照改性后进行了模压发泡,并对发泡材料的性能进行了研究.结果表明:随着辐照剂量的增加,泡孔结构越细密均匀,弯曲模量逐渐升高,维卡软化点逐渐提高,说明经辐照改性后的聚丙烯没有出现泡孔合并现象,有较好的发泡性能.
The foaming property of polypropylene under certain irradiation dose was discussed with the method of mould foaming.The result is that： as the irradiation dose increasing,the cell structure becomes small and uniform,the flexural modulus and vicat softening temperature increase gradually.It indicates that polypropylene under certain irradiation had a finer foaming property and the break of cell wall didn＇t happen within the foaming process.
