Abstract

In this work, microcellular acrylonitrile-butadiene-styrene foams were developed with utilization of water as a co-blowing agent and CO2 as the primary blowing agent through the solid-state batch foaming process. The effect of saturation parameters with the content of the co-blowing agent has been studied extensively for various foaming attributes. The co-blowing agent enhanced the average cell size and the expansion ratio which are useful for better thermal insulation. The maximum expansion ratio of 29.9 obtained from the effect of saturation temperature and co-blowing agent, 23.6 from the effect of saturation pressure and co-blowing agent, and 22.4 from the effect of saturation time and co-blowing agent. The co-blowing agent significantly affects the cell morphology of polymeric foam with saturation parameters.

以水为共发泡剂,采用co2诱导固态间歇发泡技术制备的超低密度微孔泡沫复合材料的形态评价
以水为助发泡剂,以CO2为主发泡剂,采用固态间歇发泡工艺制备了微孔丙烯腈-丁二烯-苯乙烯泡沫。研究了饱和参数随助发泡剂含量的变化对不同发泡性能的影响。共发泡剂提高了电池的平均尺寸和膨胀率,有利于提高保温性能。饱和温度和共发泡剂的影响下膨胀比最大为29.9,饱和压力和共发泡剂的影响下膨胀比最大为23.6,饱和时间和共发泡剂的影响下膨胀比最大为22.4。共发泡剂对含饱和参数聚合物泡沫的细胞形态有显著影响。

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.
