Over the past decade, with the emergence of environmental and human health concerns, research has focused on developing new solutions to replace fossil resources with more sustainable biobased resources. Furan derivatives can be obtained from plants, and their structures provide high resistance to high temperatures. Furan derivatives have been functionalized with phosphorus (P) to increase their fire-resistance properties. Thus, a new biobased bisfuran containing nitrogen and phosphorus (diethyl (((3-((((diethoxyphosphoryl)(hydroxy)(4-(hydroxymethyl)cyclopenta-1,3-dien-1-yl)methyl)amino)methyl)benzyl)amino)(hydroxy)(4-(hydroxymethyl)cyclopenta-1,3-dien-1-yl)methyl)phosphonate (HMF-MXDA-DEP)) was synthesized and used for the first time in polymerization to develop alkyd resins. The flame-retardant (FR) properties of these resins were studied. Alkyd resins are generally used as a binder in paint or varnish formulations. The use of a reactive FR during the polycondensation reaction of alkyd resins makes it possible to form covalent bonds and offer better durability over time. The impact of HMF-MXDA-DEP on film properties such as drying time, flexibility, adhesion and color was studied, and the thermal and FR properties were evaluated by differential scanning calorimetry, thermogravimetric analysis and pyrolysis–combustion flow calorimetry. Increased thermal stability and good FR properties of alkyd resins were demonstrated. In the cone calorimeter test, the lowest peak heat release rate (pHRR) was obtained with a coating of 2 wt% phosphorus HMF-MXDA-DEP on wood, and a 49% decrease in pHRR compared with that of FR-free alkyd resins was demonstrated.

磷酸化含呋喃醇酸树脂的阻燃性能

在过去的十年中，随着环境和人类健康问题的出现，研究重点是开发新的解决方案，用更可持续的生物基资源替代化石资源。呋喃衍生物可以从植物中获得，其结构具有很高的耐高温性。呋喃衍生物已用磷 (P) 进行功能化，以提高其耐火性能。因此，一种含有氮和磷的新型生物基双呋喃（二乙基（（3-（（（二乙氧基磷酰基）（羟基）（4-（羟甲基）环戊-1,3-二烯-1-基）甲基）氨基）甲基）合成了苯甲基）氨基）（羟基）（4-（羟甲基）环戊-1,3-二烯-1-基）甲基）膦酸酯（HMF-MXDA-DEP）），并首次用于聚合开发醇酸树脂。研究了这些树脂的阻燃（FR）性能。醇酸树脂通常用作油漆或清漆配方中的粘合剂。在醇酸树脂的缩聚反应过程中使用反应性阻燃剂可以形成共价键并提供更好的耐久性。研究了HMF-MXDA-DEP对干燥时间、柔韧性、附着力和颜色等薄膜性能的影响，并通过差示扫描量热法、热重分析和热解-燃烧流动量热法评估了热性能和阻燃性能。醇酸树脂的热稳定性提高并具有良好的阻燃性能。在锥形量热仪测试中，木材上涂覆 2 wt% 磷 HMF-MXDA-DEP 时获得了最低的峰值放热率 (pHRR)，与不含 FR 的醇酸树脂相比，pHRR 降低了 49%证明了。
