摘要

当前由温室效应和“双碳”目标掀起的新一轮制冷剂替代浪潮，要求新型制冷剂需在环保性、安全性和热物性等方面达到综合平衡。然而目前尚不存在一种完美替代制冷剂，如备受关注的低ODP、GWP制冷剂R290、R32、R1234yf等大多均存在安全隐患。为这些环保可燃制冷剂寻找性能优良的匹配阻燃剂，已成为现阶段制冷剂替代研究的重要方向之一。总结了近年来可燃制冷剂匹配阻燃剂的研究进展，主要针对不同种类的阻燃剂，概述了其对不同的可燃工质的阻燃效果评价，从阻燃性能、阻燃效果、阻燃机理和环保性能等角度进行详细阐述，并分析了其应用前景和发展趋势，给出可燃工质匹配阻燃剂的选择建议。

Abstract

The current greenhouse effect and the "dual-carbon" goal have set off a new wave of refrigerant substitution

requiring new refrigerants to achieve a comprehensive balance between environmental protection

safety and thermal properties. However

there are currently no ideal substitutes for these refrigerants. Most environmentally friendly refrigerants

such as R290

R32

and R1234yf

which have low ozone depletion potential (ODP) and Global Warming Potential (GWP)

are flammable and pose safety risks. Identifying suitable flame retardants for environmentally friendly flammable refrigerants has emerged as a crucial focus of current research on refrigerant alternatives. This article provides a recent overview of research progress on the compatibility of flame retardants with flammable refrigerants. The main focus was categorizing the various flame retardants and assessing their efficacy across different flammable substances. It also discusses their performance

effects

mechanisms

and environmental impacts. Furthermore

the article analyzes their potential applications and development trends and recommends flame retardants compatible with flammable substances.
