Application of aluminum diethyl hypophosphite, iron-based metal organic framework-NH2-MIL-53(Fe), and expandable graphite complexes as flame retardants for high-density polyethylene
High-density polyethylene (HDPE) composites are made by melt blending HDPE with MIL-53(Fe), amino-functionalized NH2-MIL-53(Fe), aluminum diethyl hypophosphite (ADP), and expandable graphite (EG). The experimental disclosed showed that the aminated NH2-MIL-53(Fe) could improve residual carbon quality and exert a better flame retardant effect than MIL-53(Fe). When 25 wt% of EG/ADP/NH2-MIL-53(Fe) was added and the ratio of EG to ADP/ NH2-MIL-53(Fe) was 1:1, HDPE/EG/ADP/NH2-MIL-53(Fe) composites could achieve a limiting oxygen index of 31.1 %, which passed UL-94 testing and was rated V-0. This results in a considerable improvement in flame retardant efficiency as the peak heat release rate was lowered by 83.4 % and the total heat release was reduced by 35.8 % when compared to the pure HDPE material. Therefore, NH2-MIL-53(Fe)/ADP/EG synergistic flame retardancy can lead to high flame retardancy efficiency in HDPE. This provided a new potential direction for the preparation of highly efficient flame retardants.
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.
