A Study on the Interfacial Adhesion Strength of Different Types of Calcium Carbonate Filled Poly (vinyl chloride) Composites

Abstract

The Polyvinyl-chloride (PVC) composites filled with micro-Calcium Carbonate (CaCO 3), submicro-CaCO 3 , nano-CaCO 3 and nano-coating micron CaCO 3 powder were prepared by the method of melt blending process. The tensile properties of the PVC/CaCO 3 composites were tested at the room temperature. The interfacial adhesion strength between the CaCO 3 particle and the PVC matrix was measured. The results showed that the tensile properties of the PVC/CaCO 3 composites were better than those of the pure PVC in the most conditions; the mechanical properties of the surface treated CaCO 3 filled PVC composites were better than the ones of the non-surface treated CaCO 3 filled PVC composites. The mechanical properties of the PVC composites filled with nano-coating micron heavy CaCO 3 were better than the ones of the he PVC composites filled with heavy CaCO 3 ; among the four types of CaCO 3 , the mechanical properties of the PVC composites filled common light CaCO 3 and ultra-fine light CaCO 3 were relatively better; as the interfacial interaction strength, the strength between the ultra-fine light CaCO 3 and the PVC matrix was maximum, the one between the common light CaCO 3 and the PVC matrix was minimum, the strength between the nano-coating micron heavy CaCO 3 and the matrix was bigger than that between the micron heavy CaCO 3 and the matrix, the strength between the CaCO 3 after being treated and the matrix was increased.

Development of hybrid plantain fiber/calcite particles reinforced polyvinyl chloride biocomposites for automobile applications

“…PVC is favored for its outstanding mechanical properties, corrosion resistance, flame retardancy, affordability, and easy availability. [5][6][7] PVC stands out among thermoplastics due to its unique modifiability through the incorporation of additives and fillers, resulting in advantageous composite materials. These PVC composites have successful applications in the construction, automotive, and furniture industries.…”
