摘要
Abstract
Fire-retardant wood composites were prepared by impregnation treatment with multi-component fire retardants(guanidine phosphate(GP)and boric acid(BA))and evaluated for their thermal stability and fire performance.The results showed that the impregnated wood with GP had better thermal stability,and the residual char yield increased to 26%for Wood-GP and reached 35%for Wood-GP/BA at 800℃.In addition,Wood-GP/BA exhibited excellent flame retardancy with peak heat release rate(PHRR)and total heat release(THR)of 9.0 kW/m2 and 1.2 MJ/m2,respectively,which were reduced by 89.7%and 81.5%,respectively,compared with the original wood.The guanidine phosphate and boric acid impregnation changed the thermal decomposition pathway of the wood substrate in the burning process,which led to the formation of a uniform and dense residual char layer,effectively preventing the transfer of heat and oxygen to the underlying wood,and greatly improving the flame retardancy of the wood.关键词
