  The present invention relates to a method for constructing a decorative material that is attached to a decorative surface of a wall of a house by adhesion to make up the wall.

Conventionally, as a method for applying a decorative material, there is a method in which an adhesive is applied to the back surface of the decorative material and adhered to a wall surface. (For example, refer to Patent Document 1.)
Japanese Patent Laid-Open No. 2005-220529

  However, the physical properties of the adhesive in the conventional construction method are hardly considered. Therefore, there is a problem that the decorative material is damaged when the appliance is attached to the wall surface after the decorative material is applied.

  The present invention has been made to solve the above problems, and the method for applying a cosmetic material according to the present invention is to prevent damage to the cosmetic material when an appliance is attached to the wall surface after applying the cosmetic material. Objective.

  In order to achieve the above object, the present invention is a method for constructing a decorative material that is attached to a decorative surface of a wall of a house with an adhesive to make up the wall, and has a viscosity before curing of less than 100 Pa · s. The decorative material and the decorated surface of the wall of the house are bonded through a certain adhesive. However, the viscosity is a value at 10 rpm measured at 23 ° C. with a BH viscometer No. 6 rotor.

  In a preferred embodiment of the present invention, the non-volatile content of the adhesive is greater than 44%.

  In a preferred aspect of the present invention, the decorative material construction method uses the adhesive and a double-sided tape in combination.

  In a preferred embodiment of the present invention, the decorative material is a calcium silicate plate containing diatomaceous earth.

  ADVANTAGE OF THE INVENTION According to this invention, when attaching an instrument by the retrofit to the wall surface after construction of makeup | decoration material, damage to makeup | decoration material can be prevented.

  Below, the construction method of the decorative material in this invention is demonstrated according to drawing. FIG. 1 is a plan view showing an application position of a double-sided tape and an adhesive on the back side of a decorative board in a method for applying a decorative material according to the present invention. FIG. 2 is an application of a double-sided tape and an adhesive in a method for applying a decorative material according to the present invention. It is sectional drawing which shows a position. However, these are one embodiment and are not particularly limited.

A plurality of double-sided tapes 1 are affixed in parallel to the four circumferences and the long sides of the decorative material 3. Further, an adhesive 2 is applied between the double-sided tapes.

The adhesive 2 has a viscosity of less than 100 Pa · s. When the viscosity is 100 Pa · s or more, when the adhesive is applied to the decorative material and adhered to the decorated surface of the wall of the house, the thickness of the adhesive applied first is not easily reduced, and the wall of the house The distance between the body surface to be decorated and the decorative material is increased. Moreover, the part which an adhesive agent does not interpose between the to-be-decorated surface of the wall body of a house, and the decorative material may be made. There is a possibility that the decorative material may break when an appliance such as a handrail is attached in a state where the interval between the decorative surface of the wall of the house and the decorative material is large, or in a portion where no adhesive is present. Further, when an adhesive having a high viscosity is to be applied thinly, there is a problem that it takes time to apply the adhesive.

Furthermore, it is preferable that the adhesive 2 has a nonvolatile content larger than 44%. By setting the non-volatile content to be greater than 44%, it is possible to prevent skin separation between the wall of the house and the decorative material.

The main component of the adhesive is not particularly limited, but a vinyl acetate resin or a vinyl copolymer resin having a relatively small tensile stress can be preferably used.

Furthermore, by using a double-sided tape and an adhesive in combination, it is possible to more effectively prevent the decorative material from being lifted or peeled off. By rotating the double-sided tape around all four corners without any gaps, it is possible to prevent floating and peeling from the end during construction. In particular, in the case of a decorative material with a surface coating, the decorative material itself tends to warp, so that the effect of preventing the floating and peeling of the end portion by turning a double-sided tape around the circumference is great.

Although it does not specifically limit as a double-sided tape used here, For example, what apply | coated the acrylic adhesive to the polyethylene-lamic cloth base material is used suitably. The thickness of the double-sided tape is preferably 0.1 to 0.5 mm. By setting the tape thickness to 0.1 to 0.5 mm, the distance between the decorative material and the wall surface can be reduced, and damage to the decorative material can occur when attempting to attach a handrail or other device from above the decorative material. Can be prevented.

Moreover, the decorative material 3 can be comprised with the base material 4 and the decorative layer 5 as shown in FIG. However, these are one embodiment and are not particularly limited.

As the base material, for example, a gypsum board, a slate plate, a calcium silicate plate and the like are preferably used. In particular, a calcium silicate plate containing diatomaceous earth is suitably used as a base material for an interior decorative board because it has a humidity control function and is lightweight.

As the decorative layer, for example, an acrylic resin paint or a silicon resin paint is preferably used. In addition, a photocatalyst can be applied to the surface of the decorative layer.

EXAMPLES The present invention will be described in more detail with reference to examples below, but the present invention is not limited to these examples.
