摘要

选用以聚磷酸铵为主剂的三种阻燃浸渍剂进行了椴木单板浸渍量与未燃面积的关系、马尾松处理材的氧指数、发烟等级、炭化长度以及模拟木板房屋点燃等阻燃性能的测定。每立方米马尾松木材对配方一、二、三的吸收量分别为32、30、25公斤时,可达JIS D1201-77难燃一级和JIS D1322-75抗燃一级标准、三个配方的阻燃效果按配方一、二、三的顺序提高。用配方一、二、三处理的木材可在室内常规温度、湿度条件下使用。

Abstract

Oxygen Index, Smoke Density and Char Length of APP treated Pinus massoniana were measured before and after aging. The relation between impregnating level of fire retardant and non-combustion areas was described in this paper. Fire retardancy of APP treated wood meets Class Ⅰ according to JIS D 1201-77 and JIS A 1322-75. Fire test of formulated small wood house was compared with untreated small wood house. The result showed that APP treated wood can be used for interior room.
