采用硼酸锌、玻璃粉为填料,将乙烯-醋酸乙烯酯共聚物(EVA)与三元乙丙橡胶(EPDM)进行共混交联,制得可瓷化EVA复合材料。研究结果表明:采用40%(wt,质量分数)硼酸锌,EVA∶EPDM的质量配合比为85∶15条件下,制得的可瓷化EVA复合材料的综合性能最佳,拉伸强度为12.5MPa,断裂伸长率为654%,熔体质量流动速率为1.7g/10min。
Using zinc borate and glass powder as the fillers,ethylene/vinyl acetate copolymer (EVA) and EPDM (EPDM) were crossed and blended,obtained ceramifiable EVA composite materials.The results showed that when using 40% (wt,mass fraction) of zinc borate,the mixture ratio of EVA and EPDM was 85 to 15,the ceramifiable EVA had the best comprehensive performance,the tensile strength of 12.5MPa,the elongation at break was 654%,the melt mass flow rate was 1.7g/10min.
