摘要

在本研究中，介绍了一种提高低密度聚氨酯泡沫（PUFS）力学性能的新方法。氯丁橡胶（CR）用于增强泡沫的机械性能。采用力学性能测试、傅立叶变换红外光谱（FT-IR）、扫描电子显微镜（SEM）、差示扫描量热仪（DSC）、热重分析（TGA）对含有CR（PUF/CR）和纯PUF的聚氨酯泡沫塑料（PUF）进行了表征。力学性能结果表明，含有0、1、2、3、4和5wt%CR的PUFS的拉伸强度分别为38.2、42、56.4、61.48、77.3和77.18kPa。形态学研究还表明，通过增加泡沫结构中CR的量，泡沫细胞更小、更封闭。图形摘要

Enhanced effect of chloroprene on the mechanical properties of polyurethane foams

In this research, a new method to increase the mechanical properties of the low-density polyurethane foams (PUFS) has been described. Chloroprene rubber (CR) is used as reinforcing the mechanical properties of the foam. Polyurethane foam (PUF) containing CR (PUF/CR) and pure PUF were characterized by mechanical testing, Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), Differential scanning calorimeter (DSC), Thermogravimetric analysis (TGA). The results of mechanical properties show the tensile strength of PUFS containing 0, 1, 2, 3, 4 and 5 wt% CR are 38.2, 42, 56.4, 61.48, 77.3 and 77.18 kPa, respectively. Also the morphological studies show by increasing the amount of CR in the foam structure, the foam cells are smaller and more closed. Graphical Abstract

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
