Description

[Detailed explanation of the idea]

Technical Field The present invention relates to a board-shaped interior material for construction such as insulation materials, flooring materials, and decorative ceiling panels. Conventional Example Conventionally, when attaching this type of architectural board interior material to a concrete wall, etc., adhesive was applied to the back side of the board interior material at the construction site, and then the interior material was attached to the concrete wall, etc. is normal. However, since the above-mentioned adhesive is usually a solvent-based adhesive, the working environment is very poor, and the work of applying the adhesive itself is hard labor. Technical problem of the present invention Therefore, the technical problem to be solved by the present invention is to enable this type of architectural board interior material to be easily attached to concrete walls, etc. at construction sites. . Summary of the present invention In order to solve the above technical problem, the present invention was constructed as follows. That is, the architectural plate interior material according to the present invention is
An adhesive is applied to one side of a plate-shaped base material, and a release paper is pasted on top of the adhesive. It is characterized in that it is composed of two types of adhesives, the second adhesive and the second adhesive, and both adhesives are applied with equal distribution. According to the interior material with the above structure, the adhesive can be exposed by simply peeling off the release paper provided on the interior material at the construction site, making it extremely easy to attach the interior material. . In addition, in the above configuration, two types of adhesives, a primary adhesive with excellent initial adhesion and a secondary adhesive with excellent permanent adhesive, are applied so as to be evenly distributed on one side of the plate-shaped base material. This makes it possible to reliably attach interior materials to concrete walls, etc. Furthermore, according to the above configuration, the back surface of the interior material is covered with a release paper and the adhesive is not exposed on the surface, so that the interior material itself can be easily cut with a saw. As the above-mentioned primary adhesive and secondary adhesive, known ones may be used, and for example, the adhesives shown in the following table are preferably used.

[Table] By the way, concrete walls, which are typical objects to which this interior material is pasted, generally do not have exactly smooth surfaces, but rather have uneven surfaces. Therefore, when adhering the interior material to the concrete wall, it is necessary to reliably apply the adhesive to the uneven surface of the concrete wall. Therefore, it is important to make the thickness of each adhesive layer sufficiently thick. However, instead of increasing the thickness of this adhesive layer, a highly elastic rubber layer or the like is interposed between the adhesive and the plate-like base material,
The elasticity of this rubber layer may absorb the unevenness of the concrete wall surface. Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that each embodiment relates to a heat insulating material. A first embodiment is shown in FIGS. 1 and 2. 1st,
In Figure 2, 1 is a plate-like base material, and this base material 1
A first adhesive A and a second adhesive B, which are different adhesives, are arranged alternately and in parallel at regular intervals on one side of the board. The base material 1 has a known structure, and is made by adhering a surface plate 1a such as a plywood board to the surface of a polystyrene foam layer having excellent heat insulation properties, that is, a heat insulation layer material 1b. On the other hand, each of the adhesives A and B has the same laminated structure, that is, a resilient layer material 3 such as rubber is adhered to the back surface of the heat insulating layer material 1b via a suitable adhesive 2, and the A primary adhesive 4a or a secondary adhesive 4b is applied to the surface of the layer material 3, and a tape-shaped release paper 5 is individually pasted onto each adhesive 4a, 4b. The above primary adhesive is an adhesive with excellent initial adhesion, while the secondary adhesive is an adhesive with excellent permanent adhesion. 3 and 4 show other embodiments, respectively. All of these embodiments are characterized in that the release paper 5a is formed from a single sheet. That is,
In FIG. 3, first adhesive rows A and second adhesive rows B are arranged alternately and in parallel on the back surface of the base material 1b,
on the adhesive rows, i.e. the first of each adhesive row A, B.
A large piece of release paper 5a is placed over the adhesive and the second adhesive. Furthermore, in FIG. 4, first and second adhesive spots A 1 and B ₁ are used instead of the first and second adhesive rows _A and B. The first adhesive spot A ₁ corresponds to the first adhesive row A, and the second adhesive spot B ₁ corresponds to the second adhesive row B, and these adhesive spots A ₁ , B ₁ are arranged alternately.
