摘要：本文探讨了阻燃封堵材料的阻燃膨胀性能与炭化剂种类、用量以及材料制作方法的关系。研究结果表明,材料的氧指数、烟密度与炭化剂的用量成正比,而起始膨胀时间与炭化剂的用量成反比。以直接模压成型方法制得的材料膨胀性能较好。
In this paper, the relationship among flameretardance, expansibility, type and content of carburizers and preparation of sealing flameretardant were studied. It was found that its oxygen index, smoke density were directly proportional to content of carburizer whereas its initial expanding time was inversely proportional to content of carburizer. The expansibility of the material made by means of direct moudling is better.
