Abstract The aim of this work was the development of a new MUF resin formulation with high tolerance towards water dilution, and a good overall performance in terms of physico-mechanical properties and formaldehyde emissions. For this purpose, sodium metabisulphite (MTBS) was added during melamine condensation reaction, therefore decreasing its ...

AbstractThe effect of electron beam (EB) irradiation (0 to 80 kGy) on the mechanical properties of melamine‐urea‐formaldehyde (MUF) impregnated wood prepared from Pinus sylvestris is investigated. The results of the compressive strength parallel to grain measurement demonstrate EB irradiation can enhance the mechanical properties of MUF impregnated ...

Study of influence of synthesis conditions on properties of melamine–urea formaldehyde resins
International Wood Products Journal, 2012AbstractThe aim of this work is to assess the differences in the polymeric structure and performance of melamine–urea formaldehyde (MUF) resins, when changing relevant synthesis variables: formaldehyde/amine groups [F/(NH2)2] molar ratio (both in the methylolation and the condensation steps) and the feedrate of urea during the condensation step.

The microcapsule containing phase change materials(microPCMs) with high efficiency of photothermal conversion was prepared by in-situ polymerization via ultrasonic dispersion which used capric acid(CA) as core material and nano silicon carbide(nano-SiC) modified melamine-urea-formaldehyde(MUF) resin as wall material. The nano-SiC has good cross-linking

Melamine-urea-formaldehyde impregnated bond paper (MUF) is widely used as panel coating and decorative raw paper. Inappropriate treatment of MUF may lead to environmental pollution. In this study, routine MUF and MUF treated with additional titanium (MUF-T) were subjected to fast pyrolysis, and the product properties at different temperatures were ...

Preparation and Application of Poly(melamine-urea-formaldehyde) Microcapsules Filled with Sulfur
Polymer-Plastics Technology and Engineering, 2011Poly(melamine-urea-formaldehyde) microcapsules containing sulfur were prepared by in-situ polymerization. Several preparation parameters of microcapsules were investigated by analyzing the morphology, particle size and encapsulation efficiency. The morphologies indicated that sodium dodecyl sulfonate (SDS) was a suitable surfactant.

The Performance of Melamine – Urea – Formaldehyde Resin with Palm Kernel as Filler
Advanced Materials Research, 2011Palm kernel meal (PKM) which is the by-products of palm oil industry consists of considerable amount of protein that showed its great potential to to be used as a filler of melamine-urea-formaldehyde (MUF) resin based wood adhesive. Besides, due to the high price of melamine, it is attempted to reduce the content of melamine in MUF resins to as low as ...

AbstractThe preparation of an industrially used sequential formulation of a melamine–urea–formaldehyde resin was followed with Fourier transform infrared (FTIR). The analysis allowed us to identify the increases and decreases of the main groups in the resin and to compare this system of resin analysis with results previously obtained by 13C‐NMR ...

On the performance of a melamine–urea–formaldehyde resin for decorative paper coatings
European Journal of Wood and Wood Products, 2009The decorative laminates industry is a highly competitive industrial sector. To be profitable, manufacturers of impregnated papers for surface laminated MDF and particleboards need to significantly reduce their production costs. Melamine formaldehyde resin (MF) formulations are commonly used for impregnation and coating of such papers, melamine being ...

In this paper, the effect of blocked polyurethane prepolymer (BPUP) with four R values (the ratio of –NCO to –OH) and different blending proportions on the characteristics of melamine–urea–formaldehyde (MUF) resin were first investigated. The properties of the modified adhesive systems were examined by dynamic wettability and shear strength.
