摘要:
以溴化丁基橡胶(BIIR)和聚乙烯(PE)为基体,用超临界氮气流体发泡技术制备了BIIR/PE共混泡沫材料,研究了BIIR用量对泡沫材料的密度、发泡倍率、硬度、回弹性、压缩永久变形性能、微观结构及导热性能的影响。结果表明,随着BIIR用量从0增加至40份(质量),泡沫材料的密度从0.075 g/cm3小幅增大至0.092 g/cm3,发泡倍率稍有下降;冲击回弹性能明显增强,硬度及压缩永久变形性能下降;泡孔尺寸有所减小,规整均一性提高;热导率可降至0.046 61 W/(m·K),泡沫材料的保温隔热性能得到提高。
Abstract:
Brominated butyl rubber (BIIR) and polyethylene (PE) were used as the matrix to prepare BIIR/PE blend foams by supercritical nitrogen gas fluid foaming technology, and the effects of BIIR amount on density, foaming ratio, hardness, resilience, compression set, microstructure and thermal conductivity of the foam were investigated. The results showed that the foam density increased from 0.075 g/cm3 to 0.092 g/cm3 and foaming ratio decreased slightly with the increase of BIIR amount from 0 to 40 phr (mass); the impact rebound performance was significantly enhanced, while the hardness and compression set decreased; the cell sizes reduced and uniformity of the cell improved. The thermal conductivity could be reduced to 0.046 61 W/(m·K) at the best, and the thermal insulation properties of BIIR/PE blends foams had been significantly improved.
