摘要
分别采用纳米蒙脱土(nano-MMT)、纳米碳酸钙(nano-CaCO_3)、纳米二氧化硅(nano-Si O_2)对高密度聚乙烯/反式-1,4-聚异戊二烯(HDPE/TPI)合金材料进行增强改性,考察了这3种纳米颗粒对HDPE/TPI合金力学性能及耐热性能的影响。结果表明:当HDPE与TPI的质量比为95/5时,HDPE/TPI合金具有良好的韧性,其冲击强度由纯HDPE的32.5 k J/m^2提高至51.1 k J/m^2。在此基础上,添加3%~5%的纳米颗粒能够较明显地改善该合金材料的力学性能和耐热性能;3种纳米颗粒中,nano-MMT和nano-CaCO_3的增强效果相对较好。
The high-density polyethylene/trans-1,4-polyisoprene（HDPE/TPI） alloys were reinforced by nanomontmorillonite（nano-MMT）, nano-calcium carbonate（nano-CaCO_3） and nano-silica（nano-SiO_2） respectively. The effects of the three kinds of nanoparticles on mechanical properties and heat resistance of HDPE/TPI alloys were investigated. The results show that： when the mass ratio of HDPE and TPI is 95/5, the impact strength of HDPE/TPI alloy increases to 51.1 kJ /m^2 from 32.5 kJ /m^2（pure HDPE）. In this recipe, the mechanical properties and heat resistance of the alloy can be improved preferably by adding 3%~5% of nanoparticles. Moreover, nano-MMT and nano-CaCO_3 exhibit a relatively better reinforcing effect among the three kinds of nanoparticles.
