| 摘 要： | 采用熔融共混法制备了低密度聚乙烯(LDPE)/纳米氢氧化铝(nano-ATH)复合材料,研究了nano-ATH表面改性前后对复合材料力学性能和阻燃性能的影响;利用扫描电镜(SEM)分析了nano-ATH表面改性前后在LDPE基体中的分散性。结果表明:表面改性nano-ATH使复合材料具有较高的拉伸强度和断裂伸长率;nano-ATH用量较少时,其表面改性与否对复合材料的阻燃性能基本没有影响;加入量较大时,表面改性nano-ATH使复合材料具有较好的阻燃性能,其在LDPE基体中的分散性也得到改善。

| Abstract: | LDPE/nano-ATH composite was prepared by means of melt blending method.The effect of the nano-ATH before and after modification on mechanical and flame retardant properties of the LDPE/nano-ATH composite was studied.The dispersion of the nano-ATH before and after modification in LDPE matrix was analyzed by SEM.The results show that: the tensile strength and elongation at break of the LDPE/nano-ATH composite with modified nano-ATH become better than those of the LDPE/nano-ATH composite with unmodified nano-ATH.The flame retardant property of the LDPE/nano-ATH composite with the modified or unmodified nano-ATH and the dispersion of the modified or unmodified nano-ATH in LDPE matrix exhibited slight difference at low loads;at high loads,the flame retardant property of the LDPE/nano-ATH composite with the modified nano-ATH becomes better than that of the LDPE/nano-ATH composite with the unmodified nano-ATH;the dispersion of the modified nano-ATH in LDPE matrix also becomes better than that of the unmodified nano-ATH in LDPE matrix. |
