For lack of an extinguishing agent with high-efficiency, non-toxic and environmentally friendly, a new type of extinguishing agent was fabricated to solve such an urgent problem. In this study, the zinc borate (ZB) and ferrocene (Fe(Cp)₂) were utilized as two additives for extinguishants to suppress combustion reaction and the toxicity of the tail gas was detected. The mass fraction of ZB corresponding to the optimal inhibitory effect was determined to be 0.5–1.5%, by contrast, the optimum interval of Fe(Cp)₂ was detected as 0.5–1.0%. Similarly, with the increasing proportion of the two additives, the homologous inhibitory action was gradually weakened. From the perspective of thermogravimetric analysis (TGA), it was indicated that the ZB accelerated the pyrolysis process of the extinguishant, making its thermal decomposition process more thoroughly. Meanwhile, the differential scanning calorimetry (DSC) demonstrated that the decomposition efficiency was markedly improved when the amount of ZB was maintained at 0.5–1.5%. Besides, the tail gas tests were implemented to assess the extent of toxic and harmful properties. In terms of the carbon monoxide (CO) and carbon dioxide (CO₂) generated, once the mass fraction of ZB and Fe(Cp)₂ was less than 1.5% and 1.0% respectively, the concentration of CO and CO₂ was distinctly lower than that without additives. Moreover, the inhibitory ability on nitrogen oxides (NOx) was enhanced when the mass fraction of the two additives was kept below 1.0%. The results confirmed that a more practical extinguishant was proposed and it can provide guidance for the application and development of extinguishants.

由于缺乏高效，无毒，环保的灭火剂，因此研制了一种新型的灭火剂来解决这一紧急问题。在这项研究中，硼酸锌（ZB）和二茂铁（Fe（Cp）₂）被用作灭火剂的两种添加剂，以抑制燃烧反应，并检测了尾气的毒性。相对于最佳抑制效果，ZB的质量分数确定为0.5–1.5％，相反，Fe（Cp）₂的最佳间隔检出率为0.5–1.0％。类似地，随着两种添加剂的比例增加，同源抑制作用逐渐减弱。从热重分析（TGA）的角度来看，表明ZB加速了灭火剂的热解过程，使其分解过程更加彻底。同时，差示扫描量热法（DSC）表明，当ZB的含量保持在0.5-1.5％时，分解效率得到显着提高。此外，还进行了尾气测试，以评估有毒有害特性的程度。就产生的一氧化碳（CO）和二氧化碳（CO ₂）而言，ZB和Fe（Cp）₂的质量分数分别小于1.5％和1.0％，CO和CO ₂的浓度明显低于不含添加剂的浓度。此外，当两种添加剂的质量分数保持在1.0％以下时，对氮氧化物（NOx）的抑制能力增强。结果证实提出了一种更实用的灭火剂，可以为灭火剂的应用和开发提供指导。
