摘要

为了改善竹/塑复合材料的性能,在竹粉、高密度聚乙烯复合材料的制备中,加入纳米级蒙脱土（NMMT）。试验结果显示,随着NMMT添加量的增加,竹/塑复合材料试样的吸湿率、吸水率均逐渐降低;静曲强度、弹性模量、拉伸强度和冲击性能,均呈现出先增强、后降低的趋势;复合材料的热稳定性亦得到改善。

Abstract

Nano-montmorillonite（NMMT）was added to bamboo flour（BF）to improve the properties of a bamboo-plastic composite made with high density polyethylene（HDPE）combined with BF and NMMT.The results showed that the water absorption and adsorption of the resulting composite decreased and modulus of elasticity,modulus of rupture,tensile strength and impact strength all increased as the NMMT percentage increased from 0to 4% but then decreased as further amounts of NMMT were added.However,thermal stability of the composite continued to improve as the percentage of NMMT increased.
