摘要

本文研究了以聚磷酸铵[（NH,4,）,n+2,P,n,O,3n+1,]（以下简称APP）为主剂的木材阻燃浸渍剂的应用性能。马尾松木材（Pinus massoniana Lamb）经三种配方阻燃处理后其抗弯、顺纹抗压强度平均降低6.25—8.25%;其表面对一种阻燃漆的粘附能力没有影响,对铁钉的锈蚀程度与一般水溶性木材防腐剂相近,对小白鼠（Kunming mice）基本无毒。在三个配方中以配方二属最佳。

Abstract

The effects of ammonium polyphosphate (APP) as fire retardant chemical for wood on strength, paintability, corrosivity and toxicity of wood were investigated. The results indicate that bending strength and compression strength parallel to grain of APP treated wood are lower (average 6.25-8.25%) than untreated wood. APP has no effects on paintability, corrosivity and toxicity.
