三聚氰胺浸渍纸层压阻燃地板的燃烧性能

摘要

在纤维拌胶的同时加入阻燃荆,并优化生产工艺,生产阻燃高密度纤维板作为地板基材,开发三聚氰胺浸渍纸层压阻燃地板.根据GB/T 17657-1999<人造板及饰面人造板理化性能试验方法>规定的方法,检测所生产强化地板的密度、含水率、吸水厚度膨胀率、内结合强度、静曲强度和甲醛释放量,并采用锥形量热仪测试和对比地板的燃烧性能.结果表明:生产的阻燃地板符合GB/T 18102-2007((浸渍纸层压木质地板>中规定要求,与普通强化木地板相比阻燃地板点燃时间延长了8 s,pkHRR下降了62%,Av-HRR下降了31.7%,EHC下降了11.5%,THR值下降了21.8,阻燃效果明显.%Adding fire retardant while mixing the fiber and glue,and making some appropriate changes in techmque of production, high density fiberboard as the base material for flooring was produced, then a type of new flame-retardant melamine laminate flooring was developed. According to GB / T 17657-1999 (Test methods of evaluating the properties of wood-based panels and surface decorated wood-based panels) , the density,moisture content, thickness swelling rate of water absorption,internal bond strength, MOR, formaldehyde emission were tested, and the combustion performance was compared by using Cone Calorimeter. Experimental results showed that the production of flame-retardant flooring meet the requirements of GB/T 18102-2007 (Laminate flooring). Compared with ordinary laminate wood flooring, the flame retarded flooring has extended 8 seconds to be ignited, pkHRR value of it has dropped by 62％, Avg- HRR values has fell by 31. 7％, EHC has decreased by 11. 5 ％ , and flame-retardant effect is obvious.
