Abstract
The scope of this study was to determine flame retardation on wood material dyed by eco-friendlyLiquorice (Glycyrrhiza glabra)and liquid glass mixture. Three species of wood material have been used; scotchpine (Pinus sylvestris L.), chesnut (Castanea sativa Mill.) and mahogany (Khaya ivorensis). Boiling methodwere used for extraction of Liquorice and then extract were mixed with mordant agents; Aluminum sulphate(KAl2(SO4)3.18H2O), Iron sulphate (Fe2(SO4)3.7H2O), and grape vinegar respectively in ratio 5%, 3% and 10%afterwards liquid glass added in ratio 20%. The solution applied to wood materials by using deeping method. Thecombustion test was realized according to ASTM-E 69-02 (2002) standard. The mass losses release of gasses(CO, O2) and the temperature °C differences of samples were detected for each 30 seconds during combustion.The results exhibited that the liquorice extract, mordant agents and even liquid glass had not played operative roleagainst fire effect. However the results of synthetic paint were similar, therefore eco-friendly natural colorantscould use instead of synthetic dyes where fire resistance is not desired.
