Abstract

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

氯丁二烯对聚氨酯泡沫力学性能的增强作用

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

期刊介绍： Cellular Polymers is concerned primarily with the science of foamed materials, the technology and state of the art for processing and fabricating, the engineering techniques and principles of the machines used to produce them economically, and their applications in varied and wide ranging uses where they are making an increasingly valuable contribution. Potential problems for the industry are also covered, including fire performance of materials, CFC-replacement technology, recycling and environmental legislation. Reviews of technical and commercial advances in the manufacturing and application technologies are also included. Cellular Polymers covers these and other related topics and also pays particular attention to the ways in which the science and technology of cellular polymers is being developed throughout the world.
