资源简介：
A treatment process and wood products thereof including a product formulation of a single phase solution combining a wood preservative (durable component) with a Flame Retardant component (FR) to produce a durable Flame Retardant (dFR) treated wood product. The durable component comprises a range of copper based and non-copper based wood preservatives， while the FR component comprises alkali metal silicates and alkali metal aluminate compounds. The dFR working solution undergoes chemical impregnation (treatment) followed by a heat (fixation) process step that locks the chemical into the wood making it non-leachable. The dFR treated wood products are tested for their enhanced fire performance properties. When heated， wood undergoes thermal degradation and combustion producing gases， vapors， tars and chars. Using a cone calorimeter burn test method， dFR treated wood products show a significant reduction in heat release rate， mass loss rate and smoke generated values compared to untreated radiate pine.
