“…Combining the results of residual char analysis and the smoke suppression and heat insulation mechanism of montmorillonite, 16,18,22,23 the possible flame retardant mechanism of TPEE/15AlPi‐MMT composites is shown in Figure 13. In the early stage of combustion, with the addition of AlPi‐MMT, dehydration occurs to generate vapor to take away part of the heat, on the one hand, the char layer of phosphate can be further generated after the ionic bond is broken to cover the surface of the matrix to play the role of heat and oxygen insulation, and at the same time, the dehydration of the silicate layer to produce a high‐quality char layer with a SiO structure also prevents the entry of heat and oxygen, thus preventing further combustion of the material.…”

“…In recent years, phosphorus-based flame retardants have become a hot research topic due to their excellent and efficient flame retardant properties. 22,23 Among them, organic hypophosphates such as aluminum diethyl hypophosphite (AlPi) are widely used in flame retardant systems due to their excellent flame retardancy, water resistance, and thermal stability. 24 However, in order to solve the problem of easy combustion and melt dripping of TPEE, organic hypophosphites often need to be compounded with other flame retardant components to achieve the flame retardant effect.…”

An aluminum diethyl hypophosphite intercalation‐modified montmorillonite flame retardant (AlPi‐MMT) is successfully prepared and characterized by FT‐IR, SEM, and X‐ray diffraction. It is found that thermoplastic polyester elastomer (TPEE) composites incorporating 15 wt% AlPi‐MMT flame retardant exhibited better char formation and flame retardant properties compared to those incorporating 15 wt% (4:1, w:w) AlPi and MMT. And the char residual of TPEE/AlPi‐MMT at 700°C is 16.17%, which is higher than that of TPEE/AlPi‐MMT at 13.94%. and the former can pass UL‐94 V‐0 rating test while the latter can only pass UL‐94 V‐1 rating test. Afterwards, the combustion performance of TPEE composites is characterized, and it is found that the heat release and smoke release of TPEE/AlPi‐MMT are greatly reduced compared with those of pure TPEE and TPEE/AlPi/MMT, which is a flame retardant and smoke suppressant TPEE composite. Finally, by analyzing the residual char morphology and elements of TPEE composites after combustion, the mechanism of the flame retardant AlPi‐MMT to promote char formation and flame retardancy is demonstrated.

“…However, the flame-retardant action of the bare oyster waste powders was unsatisfactory. Therefore, proper processing was highly desired in order to achieve the deconstruction and modification of layered oyster waste [ 100 ]. Firstly, they applied a simple ball milling of oyster powders, to obtain a phosphorus-free hybrid flame-retardant (TOSP), as shown in Figure 6 .…”

To meet the growing needs of public safety and sustainable development, it is highly desirable to develop flame-retardant polymer materials using a facile and low-cost method. Although conventional solution chemical synthesis has proven to be an efficient way of developing flame retardants, it often requires organic solvents and a complicated separation process. In this review, we summarize the progress made in utilizing simple ball milling (an important type of mechanochemical approach) to fabricate flame retardants and flame-retardant polymer composites. To elaborate, we first present a basic introduction to ball milling, and its crushing, exfoliating, modifying, and reacting actions, as used in the development of high-performance flame retardants. Then, we report the mixing action of ball milling, as used in the preparation of flame-retardant polymer composites, especially in the formation of multifunctional segregated structures. Hopefully, this review will provide a reference for the study of developing flame-retardant polymer materials in a facile and feasible way.

In order to obtain an efficient flame retardant and smoke suppressor without sacrificing mechanical properties of epoxy resin (EP). A cyano group‐containing 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) derivative (CP‐DOPO) was proposed and synthesized through one‐step Atherton–Todd reaction between DOPO and 4‐cyanophenol. The comprehensive performance analysis of CP‐DOPO‐based EP composite was conducted by measuring the flame retardancy, smoke suppression, and mechanical properties. The flame‐retardant test findings shows that the EP/4CP‐DOPO sample achieves UL‐94 V‐0 rating with 4 wt% low addition of CP‐DOPO. Moreover, EP/6CP‐DOPO sample presents a LOI of 36.5%, a 28.1% reduction in the peak heat release rate, and a 42.1% substantial decrease in total smoke production, demonstrating its desirable flame retardancy and smoke suppression properties. Significantly, different from the traditionally additive flame retardants, the mechanical properties of EP matrix will not be affected by the incorporation of CP‐DOPO but a 17.7% increasement of flexural properties compared to EP. This research not only provides an ingenious strategy for designing and preparing high‐effective flame retardant but also enhances the comprehensive performance of EP resins in practical applications.
