Abstract:
Seeking the reuse of solid residues, the present work produced polymeric resin compounds using the industrial residue of Red Mud, from the mining company Hydro Alunorte (Pará), with its mechanical properties of flammability. The granulometries employed were 0, 100 and 200 mesh, with proportions of 10% and 20% for each. Isophthalic unsaturated polyester resin was used, coupled to the initiator and the Cobalt accelerator in proportions of 1 % and 1,5 %, in v/v, respectively. The manual method “hand lay up” was used to manufacture the composites in metal molds. Traction, physical and flamel retardance tests were performer according to ASTM D 3039, NBR 12766 and ASTM D 635, respectively. The results of the traction resistance were satisfactory as the granulometry decreased, the best with the composition of 10 % 100# reaching 40.35 MPa of resistance. The flame resistance was also beneficially influenced by decreasing the granulometry, and the lowest burning rate that was made with the composition of 20 % 200# 16,16 mm/min. The results of the physical tests (PA, AA, MEA) varied according to the proportions and granulometry.
