In this study, the effects of potential flame retardation were investigated using aluminum anodic waste in chipboard type composite panel materials. In the blends formed by adding a 10% polymeric binder in hot water to the powdered aluminum anodizing wastes, 1% zincborate (45% ZnO - 36% B2O3), mainly calcium carbonate (CaCO3), and sodium bicarbonate (NaHCO3) as much as waste were respectively in mass ratios added to the chipboard coats and the coatings were left to dry at 50 degrees C, 24 hours. A limiting oxygen index (LOI) test was performed at a feed rate of 27-38% O-2 according to ASTM D 2863 and flame retardance times of 180-200 seconds were observed. The longest flame retardance time was found to be 200 seconds with 38% O-2 feed. In the classification according to the LOI test it was determined that this value is an extra flame retardant. In addition, these coatings were held for 3 months at extreme temperatures of -18 degrees C and 50 degrees C, and there was no change in their physical appearance. In the XRD analysis of the coatings, intensely of Al(OH)(3) and Al2O3, trace amount of SiO2, CaO and MgO were observed in both mixtures. It has been found here that aluminum compounds have flame retardant effect. In the TG-DTA analysis, mass loss of 38% in the mixture of containing zinc borate and 37% in the mixture of containing sodium bicarbonate was observed between 568-778 degrees C. Aluminum anodized waste can be used in fire retardant production as well as harmless for human health and environmentally friendly composite panels were obtained.
