Effect of Addition of Phosphates on Thermal, Physical and Mechanical Properties of Phenolic and Amino Bonded Wood Composite

B. S. Mamatha, D. Sujatha, D. N. Uday, A. Nandanwar


Properties of flame retardant molecule board made by treating the molecule (crowded deltoids) with mono ammonium hosphate/diammonium phosphate (MAP/DAP) creation were examined. Two convergences of (0, 1, and 2%) of flame retardants ere joined to the particles on broiler dry weight of the particles. Melamine Urea Formaldehyde tar (MUF) and phenol formaldehyde pitch (PF) were utilized to produce the exploratory boards. The fire
retardancy and warm strength of the composites was contemplated by utilizing restricting oxygen file test (LOI) and thermogravimetric investigation (TGA), separately. The fire retardant molecule board, tests have been tried for flame retardancy according to Indian
standard May be: 5509/IS 1734(part-3) for combustibility, and rate of consuming tests. Physical and mechanical properties of the board were assessed according to the standard May be: 3087.The fire retardancy of the samples indicated time duration higher than the
required for the fire retardant test as per IS: 5509 with increased LOI values for PF bonded boards. TGA studies confirmed the thermal stability of the particle board. The study indicates that the addition of fire retardant chemicals by particle treatment depends on the percentage level and also the type of adhesive used to make wood composite to yield excellent fire properties without deteriorating the physical and mechanical properties of the boards.
