| 摘 要： | 用原位气泡拉伸(ISBS)法制备低密度聚乙烯(LDPE)/纳米Mg(OH)2复合材料。结果表明,ISBS法对LDPE基体中的纳米Mg(OH)2具有良好的分散能力,被分散的纳米粒子没有重新团聚。ISBS法制备的纳米复合材料的力学性能优于双螺杆剪切分散制备的复合材料的性能。复合材料的拉伸强度随着纳米Mg(OH)2添加量的增加而增大,在添加量为15份时达到最大值,然后随着添加量的增加而下降,但仍然远高于纯LDPE的拉伸强度。

| Abstract: | Low density polyethylene/nano-magnesium hydroxide composites were prepared by in-situ bubble stretching(ISBS) method and simple shear method.The results showed that the ISBS method led to a high degree of dispersion of Mg(OH)2 nanoparticles in LDPE matrix.Furthermore,no significant re-aggregation of the nanoparticles was observed.The tensile strengths of nanocomposites prepared by means of ISBS method were higher than those of materials with the same Mg(OH)2 loading produced by direct blending/extrusion.The tensile strength of the nanocomposites produced by ISBS method reached a maximum value at Mg(OH)2 content of 15 phr. |
