Description
Technical field
The present invention relates to a kind of wooden be folded anti-wet-sheet, anti-deformation wood based panel and decorative panel of layers on substrates, in further detail, it relates to and a kind ofly not only has the variation that prevents because of the temperature humidity environment to cause wooden be the function of the moisture absorption of base material and the wet distortion that is produced of loosing, and can prevent wet-sheet from wooden be that base material peels off and protruding anti-wet-sheet, anti-deformation wood based panel and decorative panel.
Background technology
In the past, wooden at wood gluing plate, medium density fibre board (MDF) (MDF), hardboard, hardboard etc. is the surfacing that the decorative panel of the superficial layer closed assembly spike material of base material is used as door, sliding door, partition etc.
Wooden be that the moisture content of base material is under the low situation of the equilibrium moisture content of base material than wooden under the outside air condition, one side moisture absorption, the suction of the decoration sheet of stacked decorative panel never, so, this surface expansion.Otherwise, wooden be that the moisture content of base material is under the high situation of the equilibrium moisture content of base material than wooden under the outside air condition, wet, the draining of loosing is shunk then.On the other hand, the one side of stacked decoration sheet moisture absorption and loose wet, suction and draining hardly.Therefore, the one side of the decoration sheet of stacked decorative panel with wooden be that the expansion rate or the shrinkage factor of the one side exposed of base material is different, decorative panel produces distortion, finally causes commodity value to descend.
As preventing that this wooden method that is base material is out of shape from for example having: thus the abundant decorative panels of reinforcing such as employing metal make its indeformable method, at superficial layer press-fit the rear side of the decorative panel of spike material, wetly cause the moisture content of wood substrates to change and the method for applying coatings in order to prevent to loose from the moisture absorption of the back side one side of decorative panel, the back side one side of the decorative panel of stacked decoration sheet on the surface, stacked polyvinyl chloride, polyethylene, the method of synthetic resin sheet materials such as polypropylene, the method of the anti-wet-sheet (for example, with reference to patent documentation 1) that perhaps stacked paper/polyethylene/paper constitutes etc.
According to the method for above-mentioned reinforcing decorative panel, just can prevent distortion by reinforcing, still, under the situation of the structure that can't reinforce, such problem will appear can't preventing to be out of shape as flush door.For the method for applying coatings since wooden be that the suction of coating of substrate surface is strong, and the smoothness on surface is poor, therefore, is difficult to form damp proof uniformly, watertight composition.
On the other hand, the method for stacked synthetic resin sheet material or anti-wet-sheet also can be applicable to flush door, owing to can prevent distortion to a certain extent, therefore, it is widely used.

Therefore, it is good that the inventor has developed a kind of moisture-proof characteristic, and in door, sliding door, partition etc., use in the place that the temperature humidity environment difference in both sides is bigger, also can prevent distortion, the anti-wet-sheet (special hope 2007-134971 number) that can not cause commodity value to descend.
Moisture permeability (JIS Z 0280) that should anti-wet-sheet is below 2.0g/m224 hour, therefore, compares with the anti-wet-sheet that synthetic resin sheet material such as polyvinyl chloride, polyethylene, polypropylene or paper/polyethylene/paper constitute, and has extraordinary moisture-proof characteristic.In addition, used the decorative panel of above-mentioned anti-wet-sheet to be used in the bigger places of temperature humidity environmental difference, both sides such as door, sliding door, partition, also can deform hardly.And, use for a long time and be subjected to can not the situation of external force resistance under, can not peel off yet.
But, used deform easily and twist wooden be base material (for example MDF, hardboard etc.) the door in, four sides are not fixed, and are under a kind of state freely substantially.Therefore, this door is subjected to the influence of temperature humidity environment easily, for example, in the door of this arrival ceiling of overall height door, further deform and twist, the result, might take place anti-wet-sheet from wooden be that base material is peeled off and projection.
