摘要

为促进结构保温材料的可持续发展,以竹纤维和聚丙烯纤维为原料,制备不同密度的竹纤维/聚丙烯纤维保温复合材料,并探讨该材料作为结构保温板（SIPs）芯材的可行性。结果表明:随着密度增加,复合材料的力学性能增加,保温性能呈先升后降的趋势;综合考虑复合材料的保温性能和力学性能,当复合材料密度为0.20 g/cm,3,时,可用来代替聚苯乙烯泡沫作为结构保温板的芯材。

Abstract

To develop sustainable structural insulated materials, bamboo fiber/polypropylene thermal insulation composites, with different densities, were prepared and feasibility of the composites to be used as core materials in structural insulated panels（SIPs） were studied.The results showed that mechanical properties of the composites increased with increasing density while insulation properties first increased and then decreased. Taking into consideration of insulation and mechanical properties of the composites, it was concluded that the composite with 0.20 g/cm3 of density was suitable for replacing polystyrene foams as core materials of SIPs.
