The goal of this research is to see how the amount and particle size of calcium carbonate (CaCO) used in the foamed layer in use for PVC-coated textiles affects the thermal properties of the material. Two different particle sizes were used at various concentrations. The impact of different CaCO loadings and particle sizes on the PVC foamed layer's thermal properties were examined. Thermogravimetry (TGA and DTG) and differential scanning calorimetry (DSC) measurements were utilized to investigate the thermal properties of the PVC foamed layer and the samples have been also characterized by FTIR spectroscopy. According to the findings, the thermal stability of the foamed layer was improved with the addition of calcium carbonate. Through the higher surface area between the filler and the PVC matrix, smaller particle sizes have produced the best results. The PVC foamed layer shows also changes in FTIR spectra after adding CaCO, and the intensity of peaks increases with decreasing CaCO particle size.
本研究的目的是考察用于PVC涂层织物发泡层的碳酸钙（CaCO₃）用量和粒径如何影响材料的热性能。使用了两种不同粒径的碳酸钙，并设置了不同浓度。研究了不同碳酸钙负载量和粒径对PVC发泡层热性能的影响。采用热重分析法（TGA和DTG）和差示扫描量热法（DSC）测量来研究PVC发泡层的热性能，并且还通过傅里叶变换红外光谱（FTIR）对样品进行了表征。研究结果表明，添加碳酸钙可提高发泡层的热稳定性。由于填料与PVC基体之间具有更大的比表面积，较小粒径的碳酸钙产生了最佳效果。添加碳酸钙后，PVC发泡层的FTIR光谱也发生了变化，且峰强度随碳酸钙粒径减小而增加。
