“…Besides increased performance against biodegradation, proper protection technologies against fire are also needed for these materials to perform more reliably under conditions suitable for thermal degradation (Morrell 2002) as well as to expand into new markets. A number of studies have suggested that boron compounds can be effectively used to increase the resistance of wood-based composites against fire (Tsunoda 2001;Baysal et al 2007;Yalinkiliç et al 2007;Wang et al 2008;Kurt et al 2012;Pedieu et al 2012;Tondi et. al.…”

Fire-resistance and thermal degradation were evaluated for particleboards incorporated with colemanite and common boron-based fire retardants (zinc borate and boric acid:borax mixture). The main purpose of this study was to suggest an alternative fire retardant to be used in particleboards with low cost and considerably lower environmental impact compared to common boron-based fire retardants. For this purpose, the colemanite mineral was chosen as a raw boron mineral because of its good fire performance demonstrated previously in wood-plastic composites. The test compounds were incorporated into the furnish during the particleboard manufacturing process. Fire performance tests and thermal degradation analysis were then performed in the treated particleboard specimens. Mass loss calorimeter tests were applied to determine the oxidative thermal degradation properties of the produced particleboards, whilst thermogravimetric analyses were used to evaluate the non-oxidative thermal behavior of the particleboards. The lowest peak heat release rate and the highest activation energy values were recorded for the boric acid:borax mixture-incorporated particleboards at a loading level of 10%. Overall the results showed that colemanite had a lower fire-retardant property in the particleboards compared to the common boron-based compounds tested in the study.

“…The authors attributed this decrease to the deposition of the flame-retardant on the board fibers, or the degradation of cellulose fibers by the flame retardant. Pedieu et al (2012) reported different results for internal bond and flexural strength [49]. They found that the addition of 16% boric acid to the particleboard increased the internal bond, while a 12% fire retardant resulted in a decrease in flexural strength.…”

This study explored the development and characterization of laminated wallboard panels using renewable materials for building applications. The panels are based on cellulose nanofibrils (CNFs) as a binder and wood particles. Other additives included FiberLeanTM (microfibrillated cellulose/calcium carbonate composite), starch and fire retardant (boric acid/borax). These panels are also intended to address the environmental concerns of commercial gypsum boards. The manufacturing of the panels is via a wet-based process; hence no initial drying was required to remove the water from the CNF. It was found that the dosage of CNF (and/or FiberLeanTM) binder and the addition of starch had the largest impact upon the quality of the final product. The addition of starch was found more favorable in the presence of FiberLeanTM. The fire retardancy was induced by adding boric acid/borax (1:1). The burning test revealed that the panels treated with the fire retardant exhibited excellent burning properties comparable to that of gypsum board (inherently fire resistant). Interestingly, the addition of the boric acid/borax also appeared to increase the retention of starch in the system, leading to favorable mechanical properties.

“…To the attempts to increase fire resistance of wood belongs the treatment with boric acid, phosphoric acid, or their salts (Garba 1999;Wang et al 2004;Baysal and Yalinkilic 2005;Stevens et al 2006;Baysal et al 2007;Blasi et al 2008;Pedieu et al 2012). Recently, Terzi et al (2011) reported that wood treated with quaternary ammonia compounds shows good fire resistance.…”

Ionic liquids (ILs) have been investigated for their potential as reagents for enhancing the fire resistance of wood. The following ILs were in focus: 1-ethyl-3-methylimidazolium bromide, 1-ethyl-3-methylimidazolium tetrafluoroborate, and 1-ethyl-3-methylimidazolium hexafluorophosphate ([C2mim][PF 6 ]). Supposedly, these ILs do not dissolve or degrade wood components to a large extent. No morphologic changes were observed in any ILtreated wood samples, but they showed an enhanced fire resistance compared with that of untreated wood. Scanning electron microscopy and energy-dispersive X-ray analysis demonstrated that the ILs are penetrated into the cell walls. The wood treated with [C2mim][PF 6 ] exhibited the highest fire resistance based on thermogravimetric and differential thermal analyzer studies: it was more resistant against flaming at approximately 350°C and the subsequent glowing at higher temperatures. This enhanced fire resistance was interpreted by dehydration in the presence of the ILs under observation. In general, ILs are promising reagents for improving the thermal properties of wood.
