Enhanced Thermal and Decorative Properties of Wall Care Putty Through Cobalt Phosphate Modification

The development of energy-efficient and durable building materials has become an important area of research in modern construction technology. In the present study, a cobalt phosphate-based inorganic mixture was incorporated into commercial wall care putty to prepare decorative wall coating composites. The synthesised composites were characterised through X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and specific heat capacity measurements. The influence of cobalt phosphate incorporation on thermal stability, heat storage capability, microstructure, and decorative performance was investigated. The results indicate that cobalt phosphate-containing composites exhibit enhanced thermal resistance, improved energy dissipation characteristics, and superior durability compared with conventional wall putty. These findings suggest that cobalt phosphate-wall putty composites can serve as advanced decorative materials for sustainable and energy-efficient buildings.
