Polymer-Plastics Technology and Engineering, 2014
Polyphenylene oxide and the intumescent flame retardant were used in combination to achieve the fire-retardancy of polystyrene. The IFR system is mainly composed of ammonium polyphosphate, pentaerythritol and melamine. To solve the problems existed in the ternary IFR system, such as hydrophilicity and heterogeneity in particle size and mixing, IFR ...

A phosphorous‐nitrogen intumescent flame‐retardant, 2,2‐diethyl‐1,3‐propanediol phosphoryl melamine (DPPM), was synthesized and characterized by Fourier transform infrared spectroscopy and nuclear magnetic resonance. Flame‐retardant rigid polyurethane foams (RPUFs) with DPPM (DPPM‐RPUF) as fire‐retardant additive were prepared.

Tri (1-oxo-2,6,7-trioxa-1-phosphabicyclo[2,2,2] methylene-4) phosphate (TPMP) and microencapsulated TPMP (MC-TPMP) with a melamine resin shell, respectively, were synthesized. Their structures were characterized by IR, XPS, scanning electron microscopy (SEM), and thermogravimetry (TG) analysis.

AbstractThe first part of this investigation focused on the synthesis and characterization of a microencapsulated intumescent flame retardant (MIFR) agent. Two steps were used in the synthesis process. The structure was characterized by scanning electron microscopy, thermogravimetric anaylysis, and Fourier transform infrared spectroscopy.

AbstractIt is of great importance to enhance ability of charring formation for polystyrene (PS) to overcome non‐charring feature during burning. Here, we demonstrate a kind of ternary intumescent flame retardant composition composed by a novel ionic liquid butyltriphenylphosphonium‐chelated orthoborates (IL) with self‐expanded flame retardant, ammonium
