Description

[Detailed explanation of the invention] This invention is formed by directly applying coatings containing alkaline water such as dolomite plaster, cement mortar, plaster, and resin-based decorative materials on architectural base panels that are attached to pillars and studs. This relates to base panels that can be used as base panels.

Conventionally, the method of constructing walls with coating materials such as dolomite plaster, cement mortar, and plaster in ordinary homes has been to use lath boards made of gypsum boards with appropriate through holes, and to apply the boards to underlying structural materials such as stud rims. This was done by applying a coating material to the surface after attaching it with nails, staples, etc., and holding the coating material by the anchoring effect of the through hole.

However, gypsum board absorbs moisture from the coating material, resulting in poor curing due to lack of moisture in the coating material, especially at the adhesive interface, water absorption, expansion of the board due to moisture absorption, and moisture absorption between the board and coating material. This has caused problems such as cracking and peeling due to a significant difference in shrinkage upon drying.

The present invention aims to solve these conventional problems.

The present invention involves coating the surface of a plate-like substrate 1 made of an inorganic or organic material with a paint called NALFAULT, a product name, which is a mixture of an attack resin of polypropylene polymer and an asphalt emulsion, so that it becomes flat or uneven. This relates to an architectural base panel on which an adhesive layer 3 has been formed by drying.

Embodiments of the present invention will be described below with reference to the drawings.

1 is a plate-shaped substrate, and a plate-shaped substrate made of an inorganic or organic material such as plywood, fiberboard, wood chip board, asbestos cement board, asbestos slate board, pulp cement board, gypsum board, or synthetic resin board is used.

The plate-shaped substrate 1 may be chamfered 2 on the four circumferential surface edges as necessary.

An uneven adhesive layer 3 is formed on the surface of a plate-shaped substrate 1.

For the adhesive layer 3, a paint called Naruphalt (trade name), which is a mixture of an attack resin of polypropylene polymer and an asphalt emulsion, is used.

Additionally, if necessary, additives such as aggregates and surfactants are mixed and applied to the surface using a coating device such as a roll coater having an arbitrary cutout coating hole of 0.5 to 1077L.
The coating is applied so as to have an uneven shape of approximately 1/2 m, and is formed by drying.

The surface can also be made uneven by increasing the particle size of the aggregate.

When the four circumferential surface edges of the plate-shaped substrate 1 are chamfered 2, an adhesive layer 3 is formed on the entire surface including the chamfered portions.

The adhesive layer 3 on the chamfered portion 2 does not necessarily have to be uneven, and may be flat.

In addition, on the back side of the plate-like substrate 1, synthetic resin, asphalt, etc.
The waterproof layer 4 that prevents moisture and water absorption from the back side may be formed by applying latex or pasting a sheet-like material such as a synthetic resin sheet or metal foil.

When applying decorative coating materials 5 such as dolomite plaster, cement mortar, and resin-based coating materials using the architectural base panel obtained as described above, the base panel can be used for columns, studs, steel frames, PC, etc. Attach to a board or wooden trunk using nails, adhesive, or other metal fittings.

Then, the coating material 5 is applied to the surface of the architectural base panel with a trowel using a mortar can or the like to an arbitrary thickness once or in several times, and is dried and solidified.

Effects of the present invention: (1) The adhesion layer 3 has good adhesion to the decorative coating material 5 because it uses a paint that is a mixture of an active polypropylene polymer resin and an asphalt emulsion.

That is, a coating material having the trade name NALFAULT, which is a mixture of a resin of the atactic component APP of the polypropylene polymer and an asphalt emulsion, is commercially available.

This paint has a property of reacting with alkaline water contained in the decorative coating material 5 and becoming water-insoluble.

Therefore, when the base panel of the present invention is brought to the site and the decorative coating material 5 is applied, the paint on the adhesive layer 3 is removed from the decorative coating material 5.
Alkaline water is supplied from the reactor, and it maintains its water-insoluble properties while continuing to react with the alkaline water.

Since the decorative coating material 5 has an extremely large amount of alkaline water, the adhesive layer 3 is sufficiently supplied with alkaline water, and the water insolubility of the adhesive layer 3 is not lost.

In this way, the adhesive layer 3 maintains a water-insoluble state, so even if rainwater or moisture from the outside air enters between the decorative coating material 5 and the substrate 1, the adhesive layer 3 will be protected by the moisture.
Cannot be damaged.

In this way, the decorative coating material 5 is prevented from peeling off from the substrate 1.

(2) Also, the moisture-proofing and waterproof properties of the adhesive layer 3 prevent moisture and water from permeating through the surface, eliminating moisture shortage in the coating material 5 and expansion of the substrate.

(2) The composition of the adhesive layer 3 has elasticity as well as water-insoluble properties, and acts as a buffer layer, buffering interlayer movement caused by the difference in expansion and contraction between the coating material 5 and the substrate 1, so that it is not soluble during or after drying. This prevents coating materials from cracking and peeling.
