摘要
利用锥形量热仪和水平垂直燃烧测定仪,按照ISO5660标准,对用ZPC60-1饰面型防火涂料处理过的白桦、杨木、柳安、檀木、沙比例的耐燃时间、点燃时间、热释放速率进行了测量。通过上述参数的比较,对同种饰面型防火涂料处理过的木质基材的防火性能进行了对比研究。另外,通过计算,得出了这几种木质基材的涂覆量和耐燃时间的线性关系式,依此式可以计算出相同耐燃时间下各基材的防火涂料涂覆量及其大小顺序,即白桦>杨木>柳安>檀木>沙比例,这可为其今后的防火处理提供理论依据。
The fireproof performance of wood panels of birch, poplar, shorea spp, pao rosa and sapele which were coated with ZPC60 - 1 decorative fireproof coating were tested according to ISO5660 standard, in terms of its fire resistant time, time to ignition （TTI） and heat release rate（HRR） by use of cone calorimeter（CONE） and horizontal- vertical combustion analyzer. Fire retardant performances of the coated wood substrates were compared. By mathematical analysis, the linear relationship between coatings coverage and fire resistant time of the wood substrates was presented. Through this relation, the fire retardant coatings a- mount needed to obtain identical fire resistant time for all kinds of woods can be calculated, which followed the following sequence ： birch 〉 poplar 〉 shorea spp 〉 pao rosa 〉 sapele. The above results can be expected to provide theoretical basis for the fire retardant treatment of wood products.
