摘　　要：以乳化二苯基甲烷二异氰酸酯(EMDI)与三聚氰胺改性脲醛树脂(MUF)混合作为胶黏剂,制备室外家具型中密度纤维板(MDF-FN-EXT),探讨三聚氰胺用量、EMDI用量、热压时间对其防潮性能的影响。结果表明,以优化工艺参数EMDI用量4%,三聚氰胺用量9%,热压时间3 min制备的试板,性能指标满足GB/T 11718-2009《中密度纤维板》中室外家具型要求。Medium density fiberboard samples to be used for making exterior furniture(MDF-FN-EXT)were made with mixed adhesives of emulsified diphenyl methane di-isocyanate(EMDI)and melamine modified urea-formaldehyde resin(MUF).Effect of dosage of melamine and EMDI as well as hot pressing time on humidity resistance of the samples were evaluated.The results showed that optimum manufacturing parameters were 4%of EMDI,9%of melamine,and 3 min of hot pressing time.Properties of the samples could meet the requirements of exterior furniture type in GB/T 11718-2009.
