[Detailed description of the invention]

[0001]

FIELD OF THE INVENTION This invention relates to a waterproof decorative plate that is used primarily for construction.

[0002]

2. Description of the Related Art Conventionally, water and moisture are prevented from entering a wooden substrate by applying a waterproof treatment to the wooden substrate to prevent the wooden substrate from swelling and the decorative sheet attached to the surface from being turned up from the wooden terminal. It was known to do so.

[0003]

[Problems to be Solved by the Invention] However, the decorative sheet adhered to the surface of the wooden substrate has a defect that the decorative sheet is cracked or blistered due to moisture or moisture entering from the surface side other than at the mouth. There is. In addition, in the case of a wooden substrate having a grooved surface, moisture and moisture easily enter the grooved portion, and the decorative sheet adhered near the groove has a drawback. This invention is intended to overcome the disadvantages as described above.

[0004]

Means for Solving the Problems] This invention is Hatsusui agent is applied to the butt end and the surface of the wood substrate which butt processing has been performed, relates to a waterproofing decorative laminate decorative sheet is adhered to the surface When a wooden substrate having a grooved surface is used, it is necessary to apply a water-producing agent to the inside of the groove. Further, in order to prevent moisture or moisture from entering from the back surface of the wooden substrate, a waterproof treatment can be applied to the back surface of the wooden substrate.

EXAMPLES detail along the invented embodiment FIG. FIG.
To 3 is an embodiment of this invention either, 1 plywood,
It is a wooden substrate made of a simple substance such as a hard board, MDF or the like or a composite thereof, and a knurl 2 or a female knurl 3 is formed at the tip of the wood substrate. It goes without saying that, instead of the ridge processing, a joint processing, a hiring processing or a simple chamfering processing may be used. In FIG. 1, the wooden substrate 1
A water repellent is applied to the tongue and the surface of the tongue. Although there are various water generating agents, those obtained by adding waxes to a hydrocarbon resin are generally used.
Brush or apply and impregnate using a spray coater or roll coater coater. The viscosity of the water-producing agent is preferably an emulsion type of 100 centipoise or less in order to impregnate the wood substrate. In the drawing, a dotted line shows a state in which the water-producing agent 4 is impregnated into the wooden mouth 1 and the surface of the wooden substrate 1. Reference numeral 5 denotes a decorative sheet such as a precious wood veneer, a decorative paper, a decorative synthetic resin sheet, etc., which is adhered to the surface of the wooden substrate with a known adhesive.

FIG. 2 shows the groove 6 formed on the surface of the wooden substrate. If the groove 6 is formed after the decorative sheet 5 is adhered, it is necessary to apply the water-producing agent to the groove 6 again. If the decorative sheet 5 is adhered to the portion of the wooden substrate 1 excluding the grooves 6 on the wooden substrate 1 in which the grooves 6 have been formed in advance, the water generating agent is applied to the surface of the wooden substrate 1 and at the same time the water generating agent is also in the grooves 6. May be applied.

FIG. 3 shows a structure in which a waterproof treatment layer 7 such as a resin-impregnated sheet or waterproof paper is formed on the back surface of the wooden substrate 1 in order to make the back surface of the wooden substrate waterproof. FIG. 3 is a diagram showing a state in which the water-absorbing agent 4 is applied in advance to the groove 6 and the surface, and then the decorative sheet 5
Is applied, and the decorative sheet 5 is cut at a portion above the groove 6 and adhered to the inside of the groove 6.

If fine cracks are formed on the surface of the wooden substrate, moisture or moisture is likely to enter even if the water-producing agent is applied. Therefore, as shown in FIG. It is an effective means to attach the nonwoven fabric 8 or to attach the MDF 9 that does not easily crack on the surface as shown in FIG. 5 to the surface of the wooden substrate 1 where cracks easily occur. At this time, the depth of the groove 6 should not be deeper than the thickness of the MDF 9, or even if it becomes deeper, should not exceed 1.5 times the thickness of the MDF 9 to prevent moisture and moisture from entering as much as possible. Is preferred.

[Effect of the invention] In the invention of claim 1, by applying a Hatsusui agent butt end and the surface of the wood substrate, suppression of change in thickness of the wood substrate by water or moisture which has penetrated from the butt portion, invading from the surface Prevents the decorative sheet attached to the surface of the wooden substrate from cracking or blistering due to moisture or moisture, and also prevents the surface from turning up from the edge of the decorative sheet due to intrusion of moisture or moisture from both the mouth and the surface there Ru.
In addition, there is also an effect of preventing the strength of the decorative board from being reduced due to the intrusion of moisture or moisture into the wooden substrate. <br/> In the invention of claim 2, by applying a Hatsusui agent enters easily the groove portion and moisture, preventing curling of the decorative sheet of the surface by water or moisture from entering from the groove portion, further This has the effect of suppressing the change in thickness of the wooden substrate and the effect of preventing the strength of the wooden substrate from decreasing. According to the third aspect of the present invention, by applying a water-producing agent to the back surface, there is an effect of suppressing the warpage of the wooden substrate due to intrusion of moisture or moisture from the back surface, thereby stabilizing the dimensions. Since the water-producing agent is applied to the entire surface of the wooden substrate, the strength of the decorative board is maintained.
