Comparative Study of Effect of Addition of Calcium Carbonate and Clay on the Performance Properties of Polyvinyl Acetate Wood Glue

Polyvinyl alcohol (PVA) stabilized acetate (PVAc) dispersions-based wood adhesive has poor water and heat resistance. Recently, the addition of fillers in is one most effective ways to enhance performance PVAc adhesive. Inorganic have unique characteristics improve adhesive, such as small size, high surface energy hardness. Hence, present work investigates applicability calcium carbonate clay incorporated 3% situ emulsion polymerization Effect on physical, thermal mechanical properties was studied by viscosity, pH, contact angle measurement, differential scanning calorimetry (DSC) pencil hardness test films. Emulsions with were prepared shear strength applied measured. The viscosity adhesives reduced case increased clay. like tensile measured a universal machine (UTM). Thermal stability (DSC). demonstrates that can bonding compared wet conditions. films also changed positively significantly improved added PVAc. Here, we did comparative study effect filler materials their different properties.
