preparation of thermoplastic polyester elastomer cerium carbonate hydroxide composites containing aluminum phosphinate with improved flame retardant and mechanical properties
Industrial & Engineering Chemistry Research, 2015Co-Authors: Wei Yang, Zhenghe Jiang, Jie Yang, Benhong YangAbstract:In this work, cerium carbonate hydroxide (CeCO3OH) was synthesized by a facile sonochemical reaction. The CeCO3OH particles were blended with thermoplastic polyester elastomer (TPEE) and aluminum phosphinate (AlP) to fabricate the fire-retardant materials. Morphology analysis results indicated that CeCO3OH was uniformly dispersed in TPEE. Thermogravimetric analysis results demonstrated that the additives composed of CeCO3OH and AlP led to the slight reduction of thermal decomposition temperature and maximum mass loss rate of TPEE composites. Compared with neat TPEE, all the TPEE/AlP/CeCO3OH composites achieved the V-0 rating in Underwriters Laboratories (UL) 94 testing. Their limiting oxygen index values were also higher than those of neat TPEE and TPEE/AlP. In cone calorimetry testing, the peak heat release rate of TPEE/12AlP/3CeCO3OH decreased from 1190 kW/m2 for neat TPEE to 530 kW/m2 with a reduction of 55%. Residue analysis showed that the presence of CeCO3OH in TPEE/AlP promoted the formation of com...

Studies on Mechanical Properties, Thermal Degradation, and Combustion Behaviors of Poly(1,4-butylene terephthalate)/Glass Fiber/Cerium Hypophosphite Composites
2014Co-Authors: Wei YangAbstract:ABSTRACT: This work aims to develop glass-fiber reinforced poly(1,4-butylene terephthalate) (GRPBT) composites with enhanced mechanical, thermal stability, and flame retardancy properties using a novel compound, cerium hypophosphite (CHP). Mechanical performance studies showed that both the storage modulus and the tensile strength increased first and then decreased with increasing CHP content. For the GRPBT composite with 15 wt % of CHP, the storage modulus value at 30 °C was 3 times that of GRPBT. Thermogravimetric analysis (TGA) illustrated that low loading of CHP could improve the thermal stability of GRPBT composites. The volatilized esters measured by TGA coupled with FTIR (TGA-FTIR) in the decomposition of GRPBT with 20 wt % of CHP are decreased by about 69%. The combustion properties were evaluated by limiting oxygen index (LOI), Underwriters Laboratories 94 (UL 94), and cone calorimeter testing. For GRPBT containing 20 wt % of CHP, it achieved a V-0 classification with a high LOI (28.5%). Additionally, the peak heat release rate (PHRR) and total smoke production (TSP) were respectively reduced by around 76 % and 45 % as compared to the results obtained from GRPBT. 1

comparison of the effects of phenyl dichlorophosphate modified and unmodified β iron iii oxide hydroxide on the thermal combustion and mechanical properties of ethylene vinyl acetate magnesium hydroxide composites
Journal of Applied Polymer Science, 2014Co-Authors: Lei Wang, Jing Zhan, Lei Song, Richard K K YuenAbstract:The objective of this study was to compare the impact of β-iron(III) oxide hydroxide [β-Fe(O)OH] and iron hydroxide modified with phenyl dichlorophosphate [β-Fe(O)OPDCP] on the thermal, combustion, and mechanical properties of ethylene–vinyl acetate (EVA)/magnesium hydroxide (MH) composites. For the EVA/MH composites in combination with these iron-containing co-additives, β-Fe(O)OH and β-Fe(O)OPDCP both led to an increase in the thermal stability at higher temperatures. The results of microscale combustion calorimetry indicate that the peak heat-release rate, total heat release, and heat-release capacity, which are indicators of a material fire hazard, all decreased. Moreover, significant improvements were obtained in the limiting oxygen index (LOI) and Underwriters Laboratories 94 ratings. However, the EVA4 system reached a V-0 rating, whereas the EVA3 system reached a V-2 rating. The LOI values for the EVA3 and EVA4 systems were 35 and 39, respectively. A homogeneous and solid structure of char residue caused by β-Fe(O)OPDCP was observed by scanning electron microscopy. Furthermore, because of the good interfacial compatibility between the fillers and the EVA matrix, the EVA4 system presented better mechanical properties than the EVA3 system. Thermogravimetric analysis/IR spectrometry showed that β-Fe(O)OPDCP reduced the combustible volatilized products of EVA/MH. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40112.
