摘要:为了获得环保型阻燃组合木材料,利用桉木旋切单板、酚醛树脂胶黏剂、Mg(OH)2阻燃剂制备阻燃组合木试样,通过拉伸试验、扫描电子显微镜、极限氧指数、热重分析对材料进行力学性能、阻燃性能测试和分析。结果表明,适量添加Mg(OH)2可以明显提高复合材料的胶合强度和阻燃性能;当添加Mg(OH)2的质量为胶黏剂固含量(胶黏剂干基质量)的1.2倍时,材料胶合强度增大48.1%,阻燃体系的极限氧指数达到36.3%;通过Mg(OH)2、Al(OH)3复配,极限氧指数进一步增大至38.7%,阻燃性能进一步提高。

Abstract: To obtain the environmental friendly flame retardant composite wood materials, composite wood material samples with flame retardant property were prepared using the wood veneer, phenolic resin adhesive and magnesium hydroxide. The mechanical property and flame retardant performance were tested and analyzed by the means of tensile test,SEM, limit oxygen index and TG. The results indicate that the addition of appropriate amount of Mg(OH)2 can obviously improve the mechanical property and flame retardant performance of composite wood materials. When the addition mass of Mg(OH)2 is 1.2 times that of the solid content of the adhesive (the mass of adhesive dry film),the bonding strength increases by 48.1% and the limit oxygen index value reaches 36.3%. By compounding Mg(OH)2 and Al(OH)3 into the composite wood materials, the limit oxygen index value increases to 38.7% .
