Abstract

Abstract: A metal–organic framework (MOF) formed between Zn and p ‐hydroxybenzoic acid (PHBA) is synthesized using a solvothermal method. These Zn‐PHBA nanorods, which are inexpensive and suitable for mass production, are added as a flame‐retardant into vinyl resin (430 LV, a material used in marine composites). Data from cone calorimetric test demonstrates that adding the Zn‐PHBA nanorods to 430 LV significantly improves flame retardation and smoke suppression. At a high Zn‐PHBA content of 10.0 wt%, the limiting oxygen index of 430 LV increases from 19.5% to 28.5%, and the material reaches the V‐0 rating in vertical burning tests (UL‐94). Moreover, the tensile and impact strengths of 430 LV containing 10 wt% Zn‐PHBA as flame‐retardant do not deteriorate and are even slightly improved. This work demonstrates that this MOF synthesized by a simple and efficient method may be used to produce nanocomposites with excellent flame retardation and mechanical properties, while keeping the material cost sufficiently low for marine applications. Abstract : This study focuses on finding an inexpensive MOF, suitable for mass production and seeking a solution for the transformation of nanocomposites from low volume/high cost to high volume/low cost under the premise of excellent flame‐retardant and smoke suppression performance.
