An epoxy oil-based fire-retardant plasticizer with a triazine ring structure (THEIC-SBOE) has been prepared by transesterification and epoxidation using tris(2-hydroxyethyl)isocyanurate and soybean oil methyl ester as the main raw materials. The structure of THEIC-SBOE has been characterized by FTIR, 1H NMR and 13C NMR spectroscopies and elemental analysis and its thermal stability has been measured by thermogravimetric analysis. Its epoxy value and acid value have been determined as 4.3 % and 0.6 mg KOH g-1, respectively. Examination of the morphology of carbon residue from PVC by scanning electron microscopy showed THEIC-SBOE to serve as an intumescent flame retardant. The results showed that, with the same plasticizer contents incorporated into PVC, THEIC-SBOE imparted similar mechanical properties as epoxidized soybean oil. Furthermore, PVC blends incorporating the synthesized plasticizer THEIC-SBOE displayed better fire-retardant properties than those incorporating dioctyl phthalate. The limiting oxygen index of such a PVC blend reached 28.4 % with 35 % (w/w) THEIC-SBOE incorporation. Source

An epoxy oil-based fire-retardant plasticiser with a triazine ring structure [tris(2-hydroxyethyl) isocyanurate-soybean oil emulsion (THEIC-SBOE)] has been prepared by transesterification and epoxidation using tris(2-hydroxyethyl) isocyanurate and soybean oil methyl ester as the main raw materials. The structure of THEIC-SBOE has been characterised by Fourier transform infrared, 1H-NMR and 13C-NMR spectroscopies and elemental analysis, and its thermal stability has been measured by thermogravimetric analysis. Its epoxy value and acid value have been determined as 4·3% and 0·60 mg·KOH g-1, respectively. Examination of the morphology of carbon residue from poly (vinyl chloride) by scanning electron microscopy showed THEIC-SBOE to serve as an intumescent flame retardant. The results showed that, with the same plasticiser contents incorporated into poly (vinyl chloride), THEIC-SBOE imparted similar mechanical properties as epoxidised soybean oil. Furthermore, poly (vinyl chloride) blends incorporating the synthesised plasticiser THEIC-SBOE displayed better fire-retardant properties than those incorporating dioctyl phthalate. The limiting oxygen index of such a poly (vinyl chloride) blend reached 28·4 with 35% (w/w) THEIC-SBOE incorporation. © W. S. Maney & Son Ltd 2015. Source

An epoxy oil-based plasticizer with a triazine ring structure (THEIC-ESBO) has been prepared using tris(2-hydroxyethyl) isocyanurate (THEIC) and soybean oil methyl ester as the main raw materials. The structure of THEIC-ESBO has been characterized by 1H NMR and 13C-NMR and elemental analysis. THEIC-ESBO substituting epoxy soybean oil (ESO) was used to plasticize PVC blends (PVC/THEIC-ESBO). when 60-70% ESO was substituted by THEIC-ESBO in PVC blends, the results of the mechanical properties and the dynamic thermomechanical analysis (DMA) indicate that plasticizing and compatibility of the plasticizer with PVC remained excellent, and the glass transition temperature (Tg) was 46.4°C. The thermal stability of PVC blends was investigated by thermogravimetric analysis (TGA). The Fire performance of the PVC/THEIC-ESBO was investigated by the limiting oxygen index (LOI) and cone calorimeter test. When THEIC-ESBO was used as plasticizers alone, the LOI of the PVC blend reached 26.1%. The cone calorimetric data show that with increasing THEIC-ESBO, the time to ignition prolong, the value of the heat release rate (HRR) and the total heat release (THR) were reduced, the total smoke of release (TSR) was increased, both of the release rate of CO and CO2 were increased, but the value of CO/CO2 was decreased, the value of the residual char yield (C-Y) was significantly enhanced. All the data indicated that flame retardant of PVC blends using THEIC-ESBO substitute ESO was significantly improved, and THEIC-ESBO exhibits flame inhibition in the gaseous phase. The mechanism of flame retardancy of PVC/THEIC-ESBO was investigated by pyrolysis gas chromatographymass spectrometry (Py-GC/MS). The results indicate that nitrogen-containing compounds from THEIC-ESBO pyrolysis dilute the concentration of combustible gases, the cross-linking reaction is also promoted the char yield. SO, during PVC blends combustion process, the flame retardant of PVC/THEIC-ESBO was enhanced. © 2015 Elsevier B.V. Source

Due to the versatility of the biomass, this article reviews the research and development of polyurethane foams based on starch, rosin, oil, cellulose and lignin. The study on biodegradable polyurethane foams become hotspot in recent years. An awareness of the various structures and compositions of renewable resource can be used to make a strong case for an increase in its production as a vital raw material for the polyurethane industries. © (2011) Trans Tech Publications, Switzerland.

Liquefaction of biomass using concentrated sulfuric acid as catalyst and methanol-glycerol complex as solvent was investigated. The liquefied products from bamboo shavings, poplar, eucalyptus and pine were neutralized, filtrated and followed by rotary evaporation. The results show that the product from liquefaction of bamboo shaving are mixture of phenolics and acetyl methyl glucoside. Polyglycoside phase mainly contains about 41.81% of polyglycosides which were mainly pyranoside, and 47.27% of unreacted glycerin and glycerin polymers. On the other hand, polyphenol phase mainly contains levulinate, polyphenols, and glycerol, and the content of glycerine and its polymers is 38.04%. Polyphenols mainly contain phenols and levulinic acid esters, and the average molecular weight of phenolics is approximate 990. ©, 2014, Editorial Board of "Chemistry and Industry of Forest Products".
