          摘要:

          摘 要:以α-磷酸鋯(α-ZrP)為協效劑,與哌嗪改性聚磷酸銨(Pa-APP)/季戊四醇(PER)復配構建膨脹型阻燃體系,研究了該阻燃體系對聚丙烯酸酯的阻燃效率,分析了其阻燃機制。正交試驗表明:當阻燃劑總添加量為25%,Pa-APP : PER=9:2以及α-ZrP含量為2%時,阻燃改性聚丙烯酸酯的LOI值達到最大值(30.4%),UL-94達到V-1等級,熱釋放峰值和總熱量釋放量相比純聚丙烯酸酯分別降低了75.9%和39.4%。通過掃描電子顯微鏡、紅外分析儀對改性聚丙烯酸酯殘炭的形貌和成分進行分析,證實Pa-APP/PER/α-ZrP復合阻燃體系能夠有效抑制熔滴,提高聚丙烯酸酯的殘炭量和改善炭層結構,降低燃燒過程中的生煙量,顯著提高改性聚丙烯酸酯的阻燃安全性能。

          Abstract:

          Abstract: α-zirconium phosphate (α-ZrP) as synergist was combined with piperazine-modified ammonium polyphosphate (Pa-APP)/pentaerythritol (PER) intumescent flame retardants to overcome the flammability and melt dropping issues of polyacrylate. The optimal addition ratio was explored through orthogonal experiments. The results show that Pa-APP/PER/α-ZrP has a prominent synergistic flame retardant effect with 25% total addition, Pa-APP:PER=9:2 and 2% α-ZrP, the maximal LOI of polyacrylate composite reached 30.4%, UL-94 achieved V-1, and the peak heat release rate (PHRR) and total heat release (THR) reduced by 75.9% and 39.4%, respectively. In addition, the morphology and composition of carbon residue were analyzed by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) and fourier transform infrared spectrum (FT-IR),the system improved the weight and quality of carbon layer of polyacrylate, which effectively inhibited the droplet and smoke generation, significantly improved the fire safety of polycrylate.
