摘要: 以微胶囊红磷(MRP)母料和聚苯醚(PPO)为复配阻燃剂,采用熔融共混法制备了无卤阻燃高抗冲聚苯乙烯(PS-HI)材料,采用氧指数、垂直燃烧法和热失重分析研究了复配阻燃剂对PS-HI的阻燃作用,对阻燃PS-HI热失重后的残留物进行红外分析。结果表明,10 %的MRP母料和18 %的PPO复配,可以使PS-HI的氧指数提高到34 %,垂直燃烧级别达到FV-0(1.5 mm)。MRP与PPO之间存在协同阻燃效应,复配阻燃剂的作用机理为凝聚相阻燃机理。

Abstract: Master batch of micro-capsulated red phosphorus (MRP) and polyphenylene oxide (PPO) were compounded forming a flame retardant, which was applied in high impact polystyrene (HIPS) via melt blending. The flame retardant effect was studied through oxygen index, vertical burning test, and thermal gravimetric analysis (TGA). Residue collected during TGA was characterized by Fourier transform infrared spectroscopy (FT-IR). It was revealed that the compound flame retardant, When the contents of MRP and PPO were 10 and 18wt%, respectively, HIPS displayed an oxygen index of 34% and a vertical burning level of FV-0 (1.5mm). There was a synergetic effect between MRP master batch and PPO, and the flame retard acted mainly in the condensed phase.
