Abstract

This paper presents the experimental work undertaken to assess rigid palm oil-based polyurethane (PU) foam. The bio-composite foam was characterized to determine its foaming kinetics and morphology, as well as fire retardancy, thermal, and mechanical responses, which was later compared with its petrochemical-based counterpart. The palm oil-based foam displayed poor fire-retardancy performance based on Limiting Oxygen Index (LOI) and UL-94 Vertical Combustion Test. Although less char residue was produced, the palm oil-based PU foam exhibited higher onset degradation temperatures, indicating improved thermal stability. The Scanning Electron Microscopy (SEM) revealed finer cell sizes for the bio-based foam and a higher fraction of open cell structures, which affected its density and compressive properties. As a conclusion, the palm oil-based PU foam is a viable alternative to be utilized in low load-bearing and thermal environment applications.
棕榈油基多元醇制备的半刚性水吹聚氨酯泡沫的阻燃性、热性能和物理机械性能
本文介绍了评估硬质棕榈油基聚氨酯(PU)泡沫的实验工作。研究人员对生物复合泡沫进行了表征,以确定其发泡动力学和形态,以及阻燃性、热学和力学响应,随后将其与石化泡沫进行了比较。根据极限氧指数(LOI)和UL-94垂直燃烧试验,棕榈油基泡沫的阻燃性能较差。虽然产生的炭渣较少,但棕榈油基PU泡沫表现出更高的起始降解温度,表明热稳定性得到改善。扫描电子显微镜(SEM)显示,生物基泡沫的细胞尺寸更小,开孔结构的比例更高,这影响了其密度和压缩性能。综上所述,棕榈油基聚氨酯泡沫是一种可行的替代品,可用于低负荷和热环境应用。

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.
