Fire Performance of Fiber Board Coated with Nano Kaolin-Clay Film

Abstract

Fiberboard is a common interior material used both in China and the United States of America. The increase in demand for interior materials has raised concerns regarding combustibility of the materials. The pyrolysis characteristics of fiber, phenolic resin (PF), and nano kaolinclay (NK) were investigated using thermogravimetry. The fire performances of samples coated with a mixture of NK and PF were determined using a cone calorimeter. The pyrolysis process of fiber included three phases dependent on chemical composition. The initial temperature of PF pyrolysis was about 100 °C and it stopped at 280°C. The major mass loss of NK was observed between 400 to 600 °C due to the gradual oxolation of the metakaolin. In comparison with fiber board, samples coated with a mixture of NK and PF achieved a better fire performance. The results showed a longer TTI, lower HRR, and THR, and less CO and CO 2 yield, especially from a mixture of NK (90%) and PF (10%). The application of an NK and PF mixture to fiber board as a flame retardant is an effective method for enhancing fire safety and resistance.

“…Both silica and alumina sheets participate in the apical O atoms . The chemical structure of K initiated many researchers to use modified K and K with IFR systems as flame retardant for polymers such as natural rubber, PP, fibre board, and polyurethane foam . Sahnoun and Bouaziz reported that the reaction of phosphoric acid and K can lead to a new phase from aluminium phosphate .…”

Flame Retardant Properties of Laminated Bamboo Lumber Treated with Monoammonium Phosphate (MAP) and Boric acid/Borax (SBX) Compounds

“…As shown on the TG curves, the untreated and treated samples underwent three degradation steps. The first degradation step of the mass loss was in the temperature range of 30 ℃ to 245 C, which is due to the removal of water from the samples (Liu et al 2013). The mass loss of the treated samples at 200 C were greater than 5%, which was due to the catalytic dehydration of monoammonium phosphate.…”
