ABS树脂无卤膨胀型阻燃研究
关键字:ABS,PA6,Ⅱ型APP,膨胀型阻燃 传统的酸源主要是APP等磷酸盐或磷酸酯,而炭源的选择主要集中在多元醇化合物方面,最常见的便是季戊四醇(PER),但是多元醇成炭剂与聚烯烃不相容,会影响材料的力学性能,且多元醇易水解,使材料有较强的吸湿性。而使用一些其它成炭性高聚物来取代多元醇可在一定程度上避免以上问题[1]。以PA6为炭源,APP为酸源的膨胀型阻燃聚稀烃体系的研究多有报道[1-5],并且取得较好的阻燃效果。但该体系用于苯乙烯类高聚物的阻燃很少有报道,因...

ABS无卤阻燃剂的合成与阻燃机理研究
关键字:ABS无卤阻燃剂 对于ABS及其合金而言,磷酸酯是有效的含磷阻燃剂,尤以磷酸三苯酯(TPP)应用最为广泛。众多报道指出,TPP能在热降解过程中生成联苯三酚磷酸(PPA),其在凝聚相重扮演热转化能垒的角色;同时生成的磷酸及其衍生物从基材或添加组分中脱水成碳。对于不含含氧官能团的ABS树脂而言,当用含磷阻燃剂处理后,燃烧时几乎不能形成碳化膜,阻燃作用不明显;另外,TPP及其同类物的挥发温度较之ABS加工温度为低,导致前者在加工过程中大量挥...
