Article Title: Flammability Characteristics of Alkaline Aqueous Solution Treated Coconut Shell - HDPE Composites
by E .Y. Ishidi, E.G. Kolawole, I.K Adamu and Obele, C.M

Alkaline aqueous solution treated and untreated coconut shell particulates were incorporated into a polymer matrix (HDPE) with the help of Two Roll Mill in order to have a homogenous mix. The treatment with aqueous sodium hydroxide solution was to roughen filler surface. Magnisuim hydroxide flame - retardant additive was incorporated to reduce the flammability of the composite. The flammability characteristics of the composite fabricated were tested using Fire Testing Technology(FTT) Dual Cone Calorimeter. The results obtained showed that the sodium hydroxide treatment enhanced the flame retardant characteristics of the composites as properties such as HRR, EHC, MLR, TSP and SEA were influenced . The filler - matrix interaction was also investigated and the images obtained at two different magnification X500 and X1000 showed enhanced compatibility of the filler - matrix for alkaline aqueous treatment of the shell
Keywords: high density polyethene, flame retardant additive, heat of fusion, flame zone, flame poisoning
