Thermal Curing Behavior and Tensile Properties of Resole Phenol-Formaldehyde Resin/Clay/Cellulose Nanocomposite*
This study investigated the effects of layered clay on the thermal curing behavior and tensile properties of resole phenol-formaldehyde (PF) resin/clay/cellulose nanocomposites. The thermal curing behavior of the nanocomposite was characterized using conventional differential scanning calorimetry (DSC) and temperature modulated (TMDSC). The addition of clay was found to accelerate resin curing,...
متن کاملThermal Degradation and Stability of Accelerated-curing Phenol-formaldehyde Resin
In order to study the thermal stability of accelerated-curing PF resin, the curing behavior of fresh PF resin was investigated in the presence of single accelerator of methylolurea derivatives (MMU), magnesium hydrate (Mg(OH)2), 25% aqueous solution of sodium carbonate (Na2CO3), and propylene carbonate (PC). Also their optimum combination was added in fresh PF resin. The thermal stability of cu...
متن کاملInfra-red Study of Structural Changes during the Pyrolysis of a Phenol-formaldehyde Resin
On pyrolysis of a phenol-formaldehyde resin at temperatures up to 700°C there was no change in the infra-red spectrum below 300°C but above this temperature the hydroxyl absorption began to decrease. This and other changes indicated the formation of diphenyl ether type linkages between benxene nuclei with the elimination of water. Above 400°C the changes which occurred in the spectra suggested ...
متن کاملStudy of the interaction between poly ( ethy 1 ene oxide ) and phenol - formaldehyde resin
Interactions between poly(ethy1ene oxide) and phenol-formaldehyde resin play important roles in the mechanism by which the two polvmers improve fibre retention in the papermaking process. These were investigated at the concentration level and shear conditions found in this vrocess. The results indicste that the comvlex formed varies with pH and ionic strength over a very narrow range of conditi...
متن کاملThermal study of phenol-formaldehyde resin modified with cashew nut shell liquid
In this study, an experimental phenol–formaldehyde resin with 20% phenol replacement by cashew nut shell liquid (CNSL) was studied and compared with a conventional phenol–formaldehyde resin synthesized totally from petrochemical rawmaterials. The resins were characterizedwith standard lab analysis for their physicochemical specifications, while their thermal properties were studied with thermog...
