【摘要】：将聚磷酸铵(APP)的高效阻燃特性与硅凝胶的吸附和催化转化特性有效结合,有可能实现木材在火灾条件下的不燃烧、不冒烟.通过真空-加压浸注和真空干燥法制备的APP硅化泡桐木载药率达到20.2%(质量分数),在锥形量热试验过程中没有点燃,760℃灼烧下不燃烧,总热释放量稍高于APP阻燃泡桐木,总烟释放量和CO产量远远低于未处理泡桐木和APP阻燃泡桐木.结果表明:APP硅化泡桐木中原位生成的APP-硅凝胶体系不仅对木材具有很好的阻燃作用,而且对火灾烟雾毒气具有极好的转化和抑制作用.
[Abstract]:It is possible to combine the highly effective flame retardant properties of ammonium polyphosphate (app) with the adsorption and catalytic conversion of silica gel to achieve non-burning and smoke free of wood under fire conditions. The drug loading rate of app silicified Paulownia wood prepared by vacuum pressure impregnation and vacuum drying was 20.2% (mass fraction). During the cone calorimetry test, the total heat release was slightly higher than that of app flame-retardant paulownia wood without burning at 760 鈩，
