摘要
用热塑性环氧酚醛树脂与纸泥制备纸泥/环氧酚醛复合材料,将含卤素的阻燃剂三-2-氯乙基膦酸盐和无机阻燃剂(如氢氧化铝)加入到环氧酚醛树脂和纸泥/环氧酚醛聚合物中,用UL-94等级燃烧测试法测定体系的燃烧等级;用热重分析仪和差示扫描量热仪对复合材料进行热分析,研究两体系的阻燃性。结果表明,含磷型阻燃剂和无机阻燃剂对环氧酚醛树脂有阻燃作用,但只有卤化和磷酸化的阻燃剂能增强纸泥/环氧酚醛复合材料的阻燃性,原因是环氧酚醛树脂材料和纸泥/环氧酚醛复合材料的阻燃性取决于本身的热容和热分解行为。
Paper-sludge/ epoxy-phenolic composites were fabricated using a novolac-type phenolic resin and paper sludge. A phosphate flame retardant containing halogen （tris-2-chloroethyl phosphate） and inorganic flame retardant （aluminum hydroxide） were introduced into neat epoxy phenolics and paper-sludge/epoxy-phenolic composite in order to improve their flame retardancy. In addition, magnesium hydroxide and halogenated flame retardant were added into the papersludge/epoxy-phenolic composite. The flame retardancies were estimated with the UL-94 test. To study the flame retardant mechanism, thermal analysis of the epoxy-phenolics and the papersludge/epoxy-phenolic composites were carried out using a thermogravimetric analyzer and a differential scanning calorimeter. The phosphated flame retardant and inorganic flame retardant both showed the flame retardant effect on the epoxy-phenolics. However, the flame retardancy of the paper-sludge/ epoxy-phenolic composite was enhanced only by phosphated and halogenated flame retardants. This result is attributed to the fact that the flame retardancies of the epoxy phenolics and paper sludge/epoxy-phenolic composite depend on their heat capacities and decomposition behaviors.
