Effect of crosslinking agent on properties and morphology of water-blown semi-rigid polyurethane foam
ABSTRACT: In this article, triethanolamine (TEOA) is used as crosslinking agent, water-blown semirigid polyurethane foams with different crosslinking agent content were prepared. The crosslinking density of polyurethane foams (PUFs) were adjusted and designed by changing the content of TEOA. The influence of crosslinking agent content on foaming process, apparent density, cell structure, microph...

Effect of Zeolites on Morphology and Properties of Water-blown Semi-rigid Ammonium Polyphosphate Intumescent Flame-retarding Polyurethane Foam
ABSTRACT: Water-blown semi-rigid polyurethane foams (SPFs) were prepared by a one-shot, free-rise method. Effect of zeolites (ZEO) on morphology, flame retardancy, mechanical properties, damping properties, and thermal properties of ammonium polyphosphate (APP) intumescent flame-retarding SPFs was studied through the analysis of rotary viscosity test, limiting oxygen index (LOI), horizontal-vert...

A novel polyurethane prepolymer as toughening agent: preparation, characterization, and its influence on mechanical and flame retardant properties of phenolic foam
A novel phosphorus- and silicon-containing polyurethane prepolymer (PSPUP) was synthesized by the chemical reaction of phenyl dichlorophosphate with hydroxy-terminated polydimethylsiloxane (HTPDMS) and subsequently with toluene-2,4-diisocyanate. The structure of PSPUP was confirmed by Fourier transform infrared spectroscopy and 1H nuclear magnetic resonance. Afterward, a series of phenolic foams (...

Synthesis and characterization of flame retardant rigid polyurethane foam based on a reactive flame retardant containing phosphazene and cyclophosphonate
A reactive flame retardant hexa-(5,5-dimethyl-1,3,2- dioxaphosphinane-hydroxyl-methyl-phenoxyl)-cyclotriphosphazene (HDPCP) was synthesized by using 5,5-dimethyl-1,3,2-dioxaphosphinane 2-oxide and hexa-(4-aldehyde-phenoxy)-cyclotriphosphazene via P-H addition reaction. And it was used to prepare flame retardant rigid polyurethane foams (FR-RPUFs). The effect of flame retardant HDPCP on physical-...

Synthesis of poly(imino imino ketone) (PIIK) and preparation of heat resistant PIIK foam
Poly(imino imino ketone) (PIIK) was synthesized via palladium-catalyzed CeN cross coupling reaction of 1,4-bis-(40-bromobenzoyl) benzene and p-phenylenediamine. In view of its good thermal stability and solubility, PIIK foams with low density between 80 mg/cm3e350 mg/cm3 have been prepared via thermal induced phase separation and freeze-drying technology. The PIIK foam possessed high glass trans...
