摘要

采用异氰酸酯胶（PMDI）制备超低密度阻燃纤维板,考察工艺因子对试板性能的影响。结果表明:随着热压温度升高、热压时间延长、PMDI用量增加,板材的力学性能及耐水性能均呈上升趋势,阻燃性能基本不变;而阻燃剂用量增加,使得板材阻燃性能增强,但耐水性能和力学性能有所降低。按优化工艺制备的板材,耐水性和力学性能满足LY/T 1718-2017干状家具型超低密度纤维板的要求,阻燃性能达到GB 8624-2012的难燃B,1,-C级。

Abstract

Ultra-low density flame-retardant fiberboard samples were manufactured with isocyanate（PMDI） resin and P-N-B flame-retardants. Effects of hot pressing temperature, pressing time, PMDI dosage and flame-retardant dosage on properties of the fiberboards were investigated.Test results showed that mechanical properties of the samples were enhanced with increase of pressing temperature and time as well PMDI dosage, while 24 h thickness swelling（TS） of the samples presented a decrease trend with unchanged oxygen index（OI）. But the mechanical properties of the samples were getting poor with increase of flame-retardant dosage, while oxygen index of the samples enhanced.Mechanical properties and flame-retardant properties of the samples made with optimized manufacturing technology could meet the requirement of LY/T 1718-2017 standard and B,1,-C grade requirement of GB8624-2012 standard, respectively.
