Abstract


Wood is one of the supreme sustainable, naturally growing materials that consist principally of combustible organic carbon compounds. Since plywood are widely used now a day especially in buildings, furniture and cabinets. Since the demand of plywood with fire retardancy properties has been increasing over last years, the objective of this study is to improve the fire retardancy of Wood Panel Products by adding Tricresyl phosphate, Di-Sodiumocta Borate and Sodium Silicate compounds as an additive in PMUF resin and used as glue for manufacture of plywood. In order to produce Fire proof board with good properties such as; fire-resistance, environmental protection and good bonding, PMUF resin has synthesized. Tricresyl phosphate (TCP), Disodiumocta-borate tetra hydrate (DOT) and Sodium Silicate was added as additive with various concentrations to prepare adhesive-mix. 12 mm plywood was manufactured and for resistance properties was studied as per IS:5509:2000. Date revels that the treated plywood shows better fire resistance properties than the untreated plywood. It has been observed that satisfactory fire retardancy properties like flame penetration and flammability was achieved when tested as per IS:5509:2000. The use of TCP and silicate not only increased the fire retardancy but also improved the bonding quality.
