GARAY, R  e  HENRIQUEZ, M. FIRE PERFORMANCE OF BOARDS AND PINE RADIATA WOOD WITH AND WITHOUT FLAME RETARDANT PAINT. Maderas, Cienc. tecnol. [online]. 2010, vol.12, n.1, pp.11-24. ISSN 0718-221X.  http://dx.doi.org/10.4067/S0718-221X2010000100002.

In housing contruction to require increase the knowledge of these materials behavior against to deterioration agents. The security opposite to the fire action is fundamental to improve their use in service. The boards tested were: radiata pine structural Plywood, Oriented Strand Board (OSB), Medium Density Fiberboard (MDF), Hard Board (HB) and particleboard, which were protected with flame retardant paint and were compared with boards without protection. Radiata pine wood with and without flame retardant paint was included in the study. The statistical analysis showed significant differences in weight loss and carbonization index for all the boards with flame retardant compared them with the boards without protection. Between structural boards: plywood and OSB, plywood with flame retardant was the one that presented best fire performance, while HB presented the worst behavior. It was demonstrated that the flame retardant paint of turns out to be effective in the protection of the boards studied on having compared with boards without protection. The implementation of this standard test was a good indicator of the fire performance and contributed with significant information of the boards, its utilization is advised as a complement to fire resistance test carried out at real scale.

Palavras-chave : wood board; flame retardant paint; fire performance; loss of weight; carbonization index.
