摘　　要：从包装减量化设计理念出发,探索了薄型稻草刨花板的制备工艺,为绿色包装设计提供材料支撑。首先在2%的MDI施胶量水平下,探索了热压温度、热压时间、酚醛胶施胶量对板材物理力学性能的影响,但在最佳工艺条件下板材的内结合强度和吸水厚度膨胀率都没有达标。将MDI的使用量提高到3%,并在热压温度为150℃、热压时间为2.0 min/mm、酚醛胶施胶量为14%、石蜡用量为1%的最佳工艺条件下,制备的薄型稻草刨花板的各种性能都达到了标准的要求。Based on the design concept of packaging reduction,the preparation technology of thin rice-straw particleboard was studied to provide material support for green packaging design.The effects of hot pressing temperature,hot pressing time and resin content of phenol formaldehyde resin（PF） on the physical and mechanical properties of the particleboard were studied under the condition of 2% MDI resin content.The internal bonding strength and thickness swelling of the thin rice-straw particleboard manufactured using the best production technology did not meet the national standard.When MDI resin content increases to 3%,the physical and mechanical properties of particleboard manufactured using the best production technology,which is the hot pressing temperature of 150 ℃,the hot pressing time of 2.0 min/mm,the PF resin content of 14%,and the liquid paraffin content of 1%,meets the requirements of the national standard.
