Significance of Wood extractives for Wood bonding
2016Co-Authors: Edmone RoffaelAbstract:Wood contains primary extractives, which are pres- ent in all Woods, and secondary extractives, which are con- fined in certain Wood species. Extractives in Wood play a major role in Wood-bonding processes, as they can contribute to or determine the bonding relevant properties of Wood such as acidity and wettability. Therefore, extractives play an im- manent role in bonding of Wood chips and Wood fibres with common synthetic adhesives such as urea-formaldehyde- resins (UF-resins) and phenol-formaldehyde-resins (PF- resins). Extractives of high acidity accelerate the curing of acid curing UF-resins and decelerate bonding with alkaline hardening PF-resins.Water-soluble extractives like free sugars are detrimental for bonding of Wood with cement. Polypheno- lic extractives (tannins) can be used as a binder in the Wood- based industry. Additionally, extractives in Wood can react with formaldehyde and reduce the formaldehyde emission of Wood-based panels. Moreover, some Wood extractives are volatile organic compounds (VOC) and insofar also relevant to the emission of VOC from Wood and Wood-based panels.

montmorillonite reinforced phenol formaldehyde resin preparation characterization and application in Wood bonding
2014Co-Authors: Qun Fang, Huiwang CuiAbstract:Abstract in this study, the montmorillonite (MMT) reinforced phenol formaldehyde (PF) resin intercalated nano-composite of PF–MMT was prepared from phenol, formaldehyde, and pristine MMT. We then introduced this PF–MMT into the production of plyWood from Simao Pine veneers. Matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF), wide-angle X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermal mechanical analysis (TMA), and bonding strength revealed the related structure, curing, and mechanical properties. The thermoplastic PF with a linear structure entered the MMT layers and then formed the network structure after cured. The wet bonding strength and modulus of elasticity (MOE) of plyWood were improved significantly. This preparation is simple and easy, and can be applied in the production of Wood industry.
