Through adopting above-mentioned technical scheme, set up the through-hole at the both ends on fire-retardant layer for gaseous and the fire extinguishing material of putting out a fire can be followed the side blowout of plywood, further improves the fire behavior of plywood.
Preferably, an aluminum alloy layer is arranged between the core plate and the flame-retardant layer.
Through adopting above-mentioned technical scheme, the holistic structural strength of plywood has been strengthened to the setting on aluminum alloy layer.
Preferably, a solid wood layer is arranged between the aluminum alloy layer and the flame-retardant layer.
Through adopting above-mentioned technical scheme, through setting up the solid wood layer, when plywood surface intensity of a fire is too big and when the intraformational fire extinguishing gas of fire-retardant and dry powder fire extinguishing material can't put out a fire, the solid wood layer is used for restraining the intensity of a fire to stretch inside the plywood, and after the plywood surface scorching, with the partial excision of surface scorching, the solid wood layer can regard as new surface course, reduces the discarded probability of plywood.
Preferably, a coating layer is arranged between the solid wood layer and the flame-retardant layer.
Through adopting above-mentioned technical scheme, fireproof coating layer between wood layer and fire-retardant layer prevents that the intensity of a fire from stretching to the wood layer surface and causing the wood layer surface to produce the burnt mark, plays the effect of protection to the wood layer surface.
Preferably, the surface of the panel is provided with a decorative layer.
Through adopting above-mentioned technical scheme, the decorative layer plays the effect of sign on the one hand, makes the plywood of this scheme and other plywood differentiation come, and on the other hand, the decorative layer can also play the effect of decoration to the plywood, makes the plywood surface more pleasing to the eye.
In summary, the present application includes at least one of the following beneficial technical effects:
the fire extinguishing gas is sprayed out from the cavity due to thermal expansion, so that the spread of fire is inhibited, and the fire resistance of the plywood is improved;
the through hole is filled with the dry powder fire extinguishing material, when the fire extinguishing gas is subjected to thermal expansion and causes the balloon to explode, the fire extinguishing gas is sprayed out from the cavity and drives the dry powder fire extinguishing material in the through hole to be sprayed out, and the fire resistance of the plywood is further improved;
be provided with the decorative layer on the surface of panel, the effect of sign is played on the one hand to the decorative layer, makes the plywood of this scheme distinguish with other plywood, and on the other hand, the decorative layer can also play the effect of decoration to the plywood, makes the plywood surface more pleasing to the eye.
