摘要：本文介紹了硬質發泡聚氨酯泡沫塑料的產生過程其反應的機理和其所得產品所擁有的特殊的性能，并通過改變發泡劑的配比結合其所得的產品的表征，找到發泡劑的最佳配比，同時改變發泡劑的用量和向原料中添加無機填料（碳酸鈣粉末），從定性和定量的角度來了解它們對聚氨酯泡沫壓縮性能的影響.用DSC差示掃描量熱儀測試樣熱性能，了解其產品的適用環境.通過這些探索性實驗對聚氨酯泡沫塑料有一個全面的了解，且對聚氨酯泡沫塑料在未來社會生活、生產中的應用前景做一定的展望。

關鍵詞：硬質聚氨酯泡沫；壓縮性能；碳酸鈣

Abstract：This article describes the rigid polyurethane foams’ generation process its reaction mechanism and its special abilities. By changing the foaming agent’s  contents and the ratio and compaired with their special income, find the best proportion of foaming agent . At the same time changing the dosage of foaming agent and adding inorganic material(CaCO3 powder) , analysis their influence to the foams’ compression
performance from the perspective of qualitative and quantitative.Using DSC differential scanning calorimeter test sample’s thermal performance.Have a comprehensive cognitive about the rigid polyurethane foams,and make a estimated about it’s application prospect in the future.
