摘　　要：以改性稻草和高密度聚乙烯(HDPE)为原料,研究了改性稻草/HDPE复合材料的热压工艺,分析了稻草改性用NaOH溶液质量分数、热压时间、HDPE加入比例等因素对复合板材性能的影响。结果表明,热压最佳工艺参数为:密度0.75g/cm3,施胶量4%,热压温度160℃,热压时间6min,HDPE加入比例30%,NaOH溶液质量分数2.5%。在此条件下制作的改性稻草/HDPE复合材料力学性能达到刨花板国家标准GB/T4897—2003要求。The hot-pressing technology for the modified straw/HDPE composites were studied using the modified straw and HDPE as raw materials. Effects of concentration of NaOH solution, hot-pressing time and HDPE content on the properties of the composites were analysed. The optimal technological parameters were obtained as board density 0.75 g/cm^3, resin content 4%, hot-pressing temperature 160 degrees C, hot-pressing time 6 minutes, HDPE content 30%, and concentration of NaOH solution 2.5%. The testing results showed that the mechanical performances of the modified straw/HDPE composites could achieve the Chinese National Standard for particle board.
