Synthesis and Characterization of Sucrose-Melamine- Formaldehyde Adhesives
The objective of this project was to use sucrose as a partial substitute for melamine in the synthesis of sucrose–melamine-formaldehyde (SMF) resin. The SMF was synthesized in a base condition. The wet bonding strength, shelf life, and formaldehyde emission of the SMF resin were determined. Fourier transform infrared spectroscopy (FT-IR) and mass spectroscopy (MS) were employed to analyze the c...
متن کاملSynthesis and Thermal Degradation Studies of Melamine Formaldehyde Resins
Melamine formaldehyde (MF) resins have been synthesized at different reaction temperature and pH values. Different molar ratios of melamine and formaldehyde were used to synthesize the corresponding resins. The prepared resin samples were characterized by using molecular weight determination viscometry and thermogravimetric analysis (TGA). The maximum percentage of solid content (69.7%) was obt...
متن کاملLiquefied Wood as a Partial Substitute of Melamine-urea- Formaldehyde and Urea-formaldehyde Resins
Maritime pine (Pinus pinaster) sawdust was used to produce liquefied wood by the polyhydric method with acid catalysis. The process was optimized to produce the highest amount of liquefied wood. Wood liquefied at 160oC for 90 min was used in the adhesion tests. The bond strength of veneer glued with ureaformaldehyde and melamine-urea-formaldehyde resins and several mixtures of liquefied wood wi...
متن کاملPreparation of Monodisperse Melamine-Formaldehyde Microspheres via Dispersed Polycondensation
We have successfully synthesized relatively monodisperse and cross-linked melamine-formaldehyde (MF) microspheres by dispersed polycondensation and subsequent pH adjustment with serum replacement cleaning. The average particle sizes ( : weight-average and : number-average), the polydispersity index ( ), the number of particles Np, and the gel content of the M-F microspheres were observed by var...
متن کاملProduction of Melamine-Formaldehyde PCM Microcapsules with Ammonia Scavenger used for Residual Formaldehyde Reduction.
Paraffinic phase change materials (PCM) were microencapsulated by in situ polymerization of melamine-formaldehyde prepolymers. Partly methylated trimethylolmelamine was used as an aminoaldehyde prepolymer for the microcapsule wall, a styrene-maleic acid anhydride copolymer as an emulsifier and modifying agent, and ammonia as a scavenger for reducing residual formaldehyde. For the determination ...
