Flame-retardant science and technology are sciences developed to prevent the occurrence of fire, meet the needs of social safety production, and protect people's lives and property. Rigid polyurethane (PU) is a polymer formed by the additional polymerization reaction of a molecule with two or more isocyanate functional groups with a polyol containing two or more reactive hydroxyl groups under a suitable catalyst and in an appropriate ratio. Rigid polyurethane foam (RPUF) is a foam-like material with a large contact area with oxygen when burning, resulting in rapid combustion. At the same time, RPUF produces a lot of toxic gases when burning and endangers human health. Improving the flame-retardant properties of RPUF is an important theme in flame-retardant science and technology. This review discusses the development of flame-retardant RPUF through the lens of bibliometrics. A total of 194 articles are analyzed, spanning from 1963 to 2021. We describe the development and focus of this theme at different stages. The various directions of this theme are discussed through keyword co-occurrence and clustering analysis. Finally, we provide reasonable perspectives about the future research direction of this theme based on the bibliometric results.
阻燃科学技术是为预防火灾发生、满足社会安全生产需求以及保护人民生命财产而发展起来的学科。硬质聚氨酯（PU）是由两个或更多异氰酸酯官能团的分子与含有两个或更多活性羟基的多元醇在合适的催化剂作用下按适当比例通过加成聚合反应形成的聚合物。硬质聚氨酯泡沫（RPUF）是一种在燃烧时与氧气接触面积大的泡沫状材料，导致快速燃烧。同时，RPUF燃烧时会产生大量有毒气体，危害人体健康。提高RPUF的阻燃性能是阻燃科学技术中的一个重要课题。本综述通过文献计量学的视角探讨了阻燃RPUF的发展。共分析了194篇文章，时间跨度从1963年到2021年。我们描述了该主题在不同阶段的发展和重点。通过关键词共现和聚类分析讨论了该主题的各个方向。最后，我们基于文献计量结果对该主题未来的研究方向提供合理的展望。
