Abstract: In this paper, the expanded and vitrified small ball (E B)/phenolic resin composite insulation board was prepared
with as thermosetting phenolic resin as adhesive, and the effect of phenolic resin content on the compressive strength, the impact
strength and thermal conductivity of the duality composite board was studied. Furthermore, the sisal fiber(SF) was used to reinforce
the phenolic resin/E VB composite board. The influence of the content and length of SF on the properties of composite board wa
also discussed. The results indicated that, the composite board showed better compressive strength, impact strength and good heat
retaining property. The impact strength of the composite board could be obviously increased when the S was mixed into th
composites. The fibers with the length of 15-20 mm showed more reinforcement effect than the fibers with the length of 5-10 mm

日前,市面上已有采用水玻璃和膨胀珍珠岩制备的新型
防火板材,但力学性能较差且耐水性不好。为改进这类复合板
近几年保温隔热材料得到了突飞猛进的发展,而上海材性能,石璞等采用膨胀珍珠岩添加耐高温粉和聚醋酸乙烯
115特大火灾和央视文沛楼等的火灾引起了人们对该类材制备出防火隔热复合板材,抗压强度达到0.81MPa,耐火性能
料防火性能的重视,传统的保温材料如聚苯乙烯泡沫、聚氨酯也有一定程度提高。吕佩娟四等借助酚醛树脂良好的力学性
泡沫等有机材料在防火性能上依然存在一些不足,而某些无能和耐高温烧蚀性能,采用聚苤乙烯泡沫颗粒和酚醛树脂制
机保温材料如岩棉等又不利于施工人员的身心健康,对于新备了一种轻质混合保温材料,但其阻燃性还有待于进一步提
型保温材料的需求迫在眉睫。
高。市面上酚醛泡沫具有其它保温复合板材所不能具有的
高防火、轻质和保温的性能,是今后保温板材发展一个主要方
