“…The burning temperature was reduced as the FR loading increased from 1.0% to 5.0%. These results were consistent with the results of Baysal (2003). FRs increase the charring rate at low temperatures and improve thermal insulation (Kolmann and Cote 1968).…”

The fire properties of particleboard coated with calcite and a variety of fireretardants (FR) was investigated. Four different chemicals, boric acid (BA), borax (BX), dolomite (DOL), and melamine (MEL), were added at the concentration of 1.0%, 3.0%, and 5.0% by oven-dry weight of calcite. The particleboard panels were tested according to the ASTM-E 69 standard to investigate their fire-retardant properties. The determination of weight loss, temperature, and the release of O2, CO, and NO by the samples was measured and recorded over 30 s intervals during combustion of the materials. The results indicated that the BA coatings exhibited better thermal stability than the other chemicals. Consequently, the lowest weight loss and temperature was found for specimens treated with 5.0% BA. These chemicals were effective relative to the fire properties of coated particleboard surfaces, depending on the type and ratio of the chemicals to the calcite.

“…The combustion process that occurs at high temperatures releases flammable gases from the wood surface. To decrease flammability, wood and wood-based materials are pretreated with fire retardant chemicals (Baysal et al 2007). Thus, it is possible to increase the usage of wood-based materials by delaying or preventing fire spread.…”

요 약 이 연구에서는 비스-디알킬아미노알킬 포스핀산(DMDAP), N,N-디메틸렌디아미노메틸-비스-포스폰산(DMDEDAP), 피 페라지노메틸-비스-포스폰산(PIPEABP), 메틸피페라지노메틸-비스-포스폰산(MPIPEABP)의 화학 첨가제로 처리된 중밀 도 섬유판(MDF)의 ABSTRACTThis study was performed to test the combustive properties of Medium Density Fibreboards (MDFs) treated with chemicals of the bis-(dimethylaminomethyl) phosphinic acid (DMDAP), N,N-dimethylethylenediaminomethyl-bis-phosphonic acid (DMDEDAP), piperazinomethyl-bis-phosphonic acid (PIPEABP), and methylpiperazinomethyl-bis-phosphonic acid (MPIPEABP). MDFs were painted in three times with 15 wt% solution of the bis-(dimethylaminomethyl) phosphinic acid and alkylenediaminoalkyl-bis-phosphonic acids at the room temperature, respectively. After drying MDF treated with chemicals, combustive properties and volatile organic compounds (VOCs) contents were examined by the cone calorimeter (ISO 5660-1), test for flame retardant (NEMA Notice No. 2012034), and gas chromatography (KS M ISO 11890-2), respectively. It was indicated that the MDFs treated with chemicals showed the longer time to combustion time (CT) = (442~492) s than that of virgin plate by reducing the burning rate except for CT treated with DMDAP. In adition, the MDFs treated with chemicals showed both of the higher char area (44.33~61.33) kg/kg and char length (10.33~11.67) cm than those of virgin plate. Especially, the MDFs treated with chemicals showed the higher mean volatile organic compounds (VOCs) (0.188~0.333) g/L than that of virgin plate within the prescribed limits. Thus, It is supposed that the combustion-retardation properties were improved by the partial due to the treated chemicals in the virgin MDF.

Four kinds of new piperazinomethyl-bis-phosphonic acid M n+ (PIPEABPM n+ ) were synthesized and their combustive properties of Pinus rigida plates treated with PIPEABPM n+ were tested. Pinus rigida specimens were painted in three times with 15 wt% PIPEABPM n+ solutions at the room temperature. After drying specimen treated with chemicals, combustive properties were examined by the cone calorimeter (ISO 5660-1). As a result, the combustion-retardation properties were increased by due to the treated PIPEABPM n+ solutions in the virgin pinus rigida. Especially, the specimens treated with PIPEABPM n+ showed both the lower peak heat release rate (HRR peak ) (162.02~145.36) s and total heat release rate (THRR) (73.0~67.4) MJ/m 2 than those of virgin piperazinomethyl-bis-phosphonic acid (PIPEABP)-plate. Compared with virgin PIPEABP-plate, the specimens treated with the PIPEABPM n+ showed low combustive properties. However the specimens treated with PIPEABPM n+ showed both the shorter time to ignition (TTI) (67~23) s and the time to flameout (Tf) (472~433) s than those of virgin PIPEABP-plate by increasing the thermal conductivity.
