| 摘 要： | 研究了5种不同木塑比的木塑复合材料的天然耐腐性能。结果表明:①木塑复合材料的天然耐腐性能为强耐腐等级,受菌侵染后质量损失率随着木粉含量的提高而增大,但均小于3.5%,方差分析表明,木粉含量对试件质量损失率的影响高度显著,指数函数y=a×exp(x/b)+c对5种木塑材料的平均质量损失率拟合结果较好,决定系数R2为0.923 58;②通过SEM和DSC分析,木塑材料受菌侵染后,主要是木质材料受到了破坏。

| Abstract: | Experiments were conducted on nature decay resistance of wood plastic composites(WPCs) with 5 different wood and plastic ratios.The results showed that nature decay resistance of WPCs was strong,the mass loss rate of specimens decayed increased with wood flour content,but always less than 3.5%.Analysis of variance demonstrated that wood flour content had great effect on mass loss rate of WPCs.Exponential function y = a×exp(x/b)+c could well fit the mean mass loss rate of 5 kinds of WPCs with determination coefficient of 0.92358.Analysis of SEM and DSC showed that wood-rotting fungi mainly decayed the wood component of the specimens. |
