摘要
近年来,火灾隐患已成为危及人们健康和安全的严重潜在问题。为了制造出多功能阻燃环氧固化物,人们非常重视采用直接技术制造多功能协同阻燃剂。本文以三聚氯氰、对羟基苯甲醛和 DOPS 为原料,通过分子结构设计合成了以 DOPS 和苯氧基三嗪为阻燃核心基团的阻燃 TFD,并将其与 EP 熔融共混,构建了阻燃热固性树脂 EP/TFD。结果表明,仅添加 10% 的 TFD 就能使 EP 通过 UL-94 V-0 测试,LOI 高达 35.3%。此外,TFD 还能有效降低环氧固化物的峰值放热率、总放热量和火势增长指数,而与纯 EP 相比,其防火性能指标则显著提高,这表明 TFD 能赋予 EP 更高的防火安全性。此外,适当添加 TFD 还能显著提高 EP 的机械韧性。与纯 EP 相比,TFD 的最大提高幅度为 46.3%。该研究项目为开发更高效的无卤阻燃剂提供了宝贵的资源。
Sulfurized DOPO synergizes with phenoxytriazine to impart epoxy thermoset fire safety, thermal stability and mechanical toughness
Fire dangers have grown to be a serious potential issue that could endanger people's health and safety in recent years. A lot of emphasis has been paid to the employment of straightforward techniques to create multifunctional synergistic flame retardants in order to create multifunctional flame retardant epoxy curing compounds. In this paper, a flame retardant TFD with DOPS and phenoxytriazine as flame retardant core groups was synthesized by molecular structure design using cyanuric chloride, p-hydroxybenzaldehyde, and DOPS as the raw materials, and it was melt blended with EP to construct a flame retardant thermoset resin EP/TFD. The results show that the addition of only 10% TFD enables EP to pass the UL-94 V-0 test with an LOI of up to 35.3%. Moreover, TFD was able to effectively reduce the peak heat release rate, total heat release, and fire growth index of epoxy curing compounds, whereas the fire performance index was significantly improved compared with that of pure EP, indicating that TFD could confer higher fire safety to EP. Moreover, TFD can significantly enhance the mechanical toughness of EP with appropriate additive amount. That is, the maximum rise compared with the pure EP enhancement of 46.3%. This program serves as a valuable resource for the advancement of halogen-free flame retardants with superior efficiency.
期刊介绍:
Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers.
Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
