摘　　要：为了减少密胺甲醛树脂(MF)包覆红磷(MFRP)在其阻燃材料加工过程中产生磷化氢气体(PH3),通过添加改性剂(乙二醇、己二胺)对MF进行改性,再包覆红磷(RP),得到改性密胺甲醛树脂包覆红磷(M-MFRP),比较了MFRP和M-MFRP阻燃处理PP加工时PH3的释放量。在PP加工条件下,添加10%(以PP质量计,下同)阻燃材料时,MFRP-PP释放24.13 mg/L的PH3,而M-MFRP-PP释放的PH3量降到8.05 mg/L。并分别对两种阻燃PP进行了阻燃性能、力学性能、热分解性能分析。结果发现,M-MFRP对PP的阻燃性能、力学性能、热分解性能以及残炭外貌的影响与MFRP差别不大,热分解挥发产物基本相同,火行为相似。In order to reduce phosphine gas(PH3) produced by red phosphorus(RP) coated by melamine formaldehyde resin(MF) during the processing of flame retardant materials, red phosphorus coated with modified melamine formaldehyde resin(M-MFRP) was prepared by modified melamine formaldehyde resin(M-MF), in which M-MF was modified by glycol or hexamethylenediamine. The release amounts of PH3 from MFRP and M-MFRP flame retardant PP(MFRP-PP and M-MFRP-PP) were compared. The results showed that when the additive amount of flame retardant was 10%(based on the mass of PP), the release amount of PH3 from MFRP-PP was 24.13 mg/L, while that from M-MFRP-PP was reduced to 8.05 mg/L, indicating that red phosphorus coated with modified MF could reduce PH3 release during the processing of PP. The flame retardant properties, mechanical properties, thermal degradation performance of the prepared MFRP-PP and M-MFRP-PP were evaluated. It was found that the effect of M-MFRP on the flame retardant properties, mechanics performance and thermal performance was similar to those of MFRP. The volatile products of thermal decomposition were basically the same and the fire behavior was similar.
