Production of Household Paint using Clay Materials

The use of clay materials for the production of emulsion paints was investigated. Two types of clay: White tinged with Purple and Smooth clay (WSP) and Grey Brown and Coarse clay (GBC), were used for the production of Emulsion Clay Paints (ECP). Conventional Chemical pigmented Paint (CP) was also produced as a control. Atomic Absorption Spectroscopy, (AAS) was used to determine the chemical composition of the clay and the concentration of heavy metals on the paints produced. Total organic content (TOC) and quality control tests were also carried out on the paints. The results of the analysis on the two clay types showed that they contained (45.26 and 47.370) % of silicon oxide and (38.26 and 35.72) % of aluminum oxide respectively. ECP has TOC values of (0.34-0.52) % while CP has TOC value of (0.29-0.31). The cost per litre of CP was (N262.17) while that of ECP was (N111.64), which is about 50% lesser.
