Abstract

In this study, mechanical properties of PVC complexes containing the gypsum (Namhae Chemical Co.) which contains phosphte, CaO, etc., Pb-species stabilizer, and $CaCO_3$ were investigated as a function or the content. As a result, mechanical properties increased when the gypsum was mixed with PVC at the extent of 8.46wt%. From this result, it is suggested that the gypsum containing phosphate and CaO is compatible with PVC. Thermogravimetric analysis(TGA) showed that pyrolysis started about at $275^{\circ}C$, and residual weight(%) increased with the amount of the gypsum, and differential scanning calorimetry (DSC) showed that $T_m,\;T_g$ had the maximum and minimum value respectively when the gypsum was mixed with PVC at the extent of 8.46wt%. Comparing all the results, both mechanical and thermal properties of PVC complex were improved. The X-ray diffraction measurement also showed their blonds and structures.
