| 摘 要： | 将甲醛溶液、多聚甲醛共同与苯酚反应,在NaOH碱性催化剂作用下,通过逐步共聚制备可发性甲阶酚醛树脂(PF),然后将可发性甲阶PF与环保型发泡剂、匀泡剂和自制复合酸固化剂混合制备了阻燃绝热PF泡沫塑料.通过对甲醛/苯酚配比(物质的量之比即F/P)进行单因素分析,重点研究了制得的PF泡沫塑料的泡孔结构、力学性能、绝热性能和阻燃性能,并通过锥形量热仪对PF泡沫塑料的燃烧性能进行了分析.结果表明,当F/P=2.0时,制得的PF泡沫塑料泡孔均匀致密,其孔径为268 μm,弯曲强度为0.24 MPa,压缩强度为0.39 MPa,热导率为0.046 W/(m·K),氧指数为54.3%,热释放速率为0.57 kW/m2,烟灰产率仅为9.6 m2/m2,峰值CO产量仅为1.8584 kg/kg. |
