Studying the Effect of Using Some of Inorganic Additives on Fire – Retardant and Mechanical Properties of Modified Unsaturated Polyester Containing Heterocyclic Ring Composites
In this work, the effect of five types of inorganic phosphors salts on flammability and mechanical properties (Flexural and Tensile) strength, of partially cross linked modified unsaturated polyester, were studied. Sheets of composites with different weight percentage of additives were prepared. Four standard test methods were used to measure the flame retardation and mechanical properties, which are: ASTM: D – 2863, ASTM: D – 635, ASTM: D – 790 and ASTM: D – 638. Results obtained from these tests indicated that, additive V has high efficiency as a flame retardant, self – extinguishing (S.E.) was occur at the percentage 1.5 % and non – burning (N.B.) was occur at the percentage 2.5 % for resin and showed high effect to reduce the values of the mechanical behaviors, but additive I has low effect on retard composition and low effect on the values of mechanical properties.
