Electron beam irradiation cross linking of halogen-free flame-retardant ethylene vinyl acetate (EVA) copolymer by silica gel microencapsulated ammonium polyphosphate and char-forming agent / Bibo Wang in Industrial & engineering chemistry research, Vol. 50 N° 9 (Mai 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 9 (Mai 2011) . - pp. 5596-5605 Titre : Electron beam irradiation cross linking of halogen-free flame-retardant ethylene vinyl acetate (EVA) copolymer by silica gel microencapsulated ammonium polyphosphate and char-forming agent Type de document : texte imprimé Auteurs : Bibo Wang, Auteur ; Qilong Tai, Auteur ; Shibin Nie, Auteur Année de publication : 2011 Article en page(s) : pp. 5596-5605 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Silica  gel  Flame  retardant Résumé : Flame-retardant ethylene vinyl acetate copolymer (EVA) by silica gel-microencapsulated ammonium polyphosphate (MCAPP) and char-forming agent (CFA) have been cross linked by electron beam irradiation. The effects of electron beam irradiation on the electrical, thermal, mechanical, and flame-retardant properties of irradiated EVA composites were investigated. The thermal degradations of EVA/MCAPP/CFA composites were characterized by real-time Fourier transform infrared spectra and thermogravimetric analysis/infrared spectrometry. The results showed that a joint effect on the flame retardancy of EVA composites existed between the MCAPP and CFA. The volume resistivity and mechanical and thermal properties of the irradiated EVA composites were also evidently improved at appropriate irradiation dose as compared with those of unirradiated EVA composites, whereas the volatilized products for the combustible gases were decreased. Furthermore, the irradiated EVA composites can still pass UL-94 V-0 rating after treatment by water for 7 days at 50 °C, indicating excellent water resistance. This investigation provides a promising formulation for the halogen-free flame-retardant EVA with excellent properties.

Intumescent flame retardation of starch containing polypropylene semibiocomposites / Shibin Nie in Industrial & engineering chemistry research, Vol. 48 N° 24 (Décembre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 24 (Décembre 2009) . - pp. 10751–10758 Titre : Intumescent flame retardation of starch containing polypropylene semibiocomposites : flame retardancy and thermal degradation Type de document : texte imprimé Auteurs : Shibin Nie, Auteur ; Lei Song, Auteur ; Yuqiang Guo, Auteur Année de publication : 2010 Article en page(s) : pp. 10751–10758 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Intumescent--Flame--Retardation--Containing--Polypropylene--Semibiocomposites--Retardancy--Thermal--Degradation Résumé : Starch containing polypropylene (SCP) semibiocomposites were prepared by melted blend method. Microencapsulated ammonium polyphosphate (MCAPP) was added to the SCP not only to improve its flame retardant properties but also to restrain the reaction between ammonium polyphosphate (APP) and starch during processing. The flame retardant properties of SCP have been investigated by limited oxygen index (LOI), UL-94 test, and cone calorimeter test. The results of cone calorimeter show that the peak of heat release rate and total heat release of SCP decreases substantially compared with that of pure PP. The thermal degradation and gas products of PP/starch/MCAPP systems were monitored by thermogravimetric analysis (TGA) and thermogravimetric analysis−infrared spectrometry (TG-IR). Scanning electron micrograph (SEM) and X-ray photoelectron spectroscopy (XPS) measurements were utilized to investigate the chemical structure, as well as the surface morphology of the residual char.
