The effects of flame retardant chemicals on the combustion resistance of wood

This study was carried out to determine the resistance properties of wood materials against burning by applying water-based varnishes modified with some natural impregnation retardants and the same natural impregnants. For this purpose; Five species of trees were used: Pinus sylvestris L., oak (Quercus petraea L.), sapland (Entandrophragma cylindricum), ash (Fraxinus excelsior L.) and rose (Dalbergia latifolia R.). The burning properties of the impregnant materials in the fire retardant property and the wood-based varnish modified with these impregnants have been determined. Water based varnish applications were made according to the standards of the impregnation and burning tests (ASTM-E 69, ASTM-D 3924 and TS2471, ASTM-D 1413 and ASTM-D3023) according to the manufacturer's recommendations. According to the results of the study, it has been determined that some natural fire retardant materials applied to wood materials and water based varnishes modified with these impregnated materials delay burning. If natural impregnants and water-based varnishes are considered to be harmless to the environment and human health, they are recommended to be used under different ambient conditions.
