摘要

以二苯基甲烷二异氰酸酯（MDI）和脲醛树脂（UF）为胶黏剂，竹加工剩余物制成的刨花制备模压托盘，采用正交试验对刨花含水率、施胶量、热压工艺等参数进行探讨。结果发现：在一定压力范围内，热压压力越大，托盘的力学性能越好，但热压温度不宜过高。在利用MDI胶制备托盘时，建议控制施胶量，避免施胶过量出现溢胶的情况；利用UF胶制备时，在一定范围内，提高施胶量利于托盘模压成型，提高表观性能。在刨花含水率10%左右，MDI添加量6%，热压压力21 MPa，热压温度125 ℃的优化工艺条件下，MDI胶制备的模压托盘满足GB/T 41231—2021《竹木刨花模压成型托盘通用技术条件》的要求；在刨花含水率4.5%左右，脲醛树脂施胶量20%，热压压力21 MPa，热压温度125 ℃的工艺条件下，脲醛胶制备的模压托盘未满足GB/T 41231—2021的要求，建议对脲醛胶进行改性后进一步优化制备工艺。

Abstract

Using diphenylmethane diisocyanate (MDI) and urea-formaldehyde resin (UF) as adhesives, bamboo residues were used to manufacture molded pallets. The results showed that within a certain hot-pressure range, the mechanical properties of the molded pallets increased with the increasing of the hot pressure. When applying MDI in the molded pallets, it was suggested to control the resin content to avoid the excessive glue overflow. When applying UF in the molded pallets, it was beneficial to molding and the appearance properties to a certain degree by increasing the resin content. The optimized process includes 10% of shavings moisture content, 6% of the MDI content, 21 MPa of hot-pressing pressure, and 125 ℃ of hot-pressing temperature. The performance of the molded pallets prepared with MDI met the requirements of the GB/T 41231—2021 ",General specification for moulded pallets with bamboo and wood particles,". At the conditions of 4.5% of shavings moisture content, 20% of UF resin content, 21 MPa of hot-pressing pressure, and 125 ℃ of hot-pressing temperature, the performance of the molded pallets prepared with UF resin did not meet the requirements of GB/T 41231—2021, it was suggested to optimize the preparation process after modify the UF resin.
