  Abstract

This study examines the cell type, compressive property, and thermal properties of rigid polyurethane foam (RPUF) that are contained egg shells (ES) as related to the ES size and content. Composed of 20 % of egg shells at 100 關m, the maximal polyol viscosity is 956.44짹14.82 mPa쨌s, the minimal cell size is 301.47짹92.56 關m, and the highest compressive property is 454.21짹25.10 kPa that is 75.65 % greater than that of pure RPUF. At the same time, the lowest thermal conductivity is 0.102짹0.005 W/mK that is 23.31 % lower than that of pure RPUF. In addition, the thermogravimetric analysis indicates that the presence of ES increases the char residues of RPUF, suggesting that ES has a positive influence on the thermal stability of RPUF. As for the combustion resistance performance of ES-contained RPUF, calcium oxide char layer occurs in the condensed phase while carbon dioxide is released in the gas phase, thereby puts out fire.
