Description

[Detailed description of the invention]

The present invention relates to a tile panel in which tiles or tile units are arranged and adhered by applying a solvent-type primer to the surface of a metal plate, and then applying an adhesive consisting of a main agent and an auxiliary agent on the primer. . Typically, tile panels are manufactured by affixing tiles or tile units in an array onto a substrate. Conventionally, tile panels are manufactured by arranging and pasting tiles or tile units onto a substrate such as a synthetic resin board, gypsum board, or plywood board. It had not been put to practical use. The reason for this is that there is no primer that sufficiently prevents metal plates from rusting, and when installing tiles and tile units on-site, there is no adhesive that firmly adheres to vertical metal plates to prevent them from slipping. This is because of this. Therefore, in view of the above-mentioned drawbacks of the conventional technology, the present invention has been developed to improve and eliminate these drawbacks, by applying an Acrylic emulsion-based primer onto a metal plate, and then applying an adhesive consisting of a main agent and an auxiliary agent onto the primer. The object is to provide a tile panel to which tiles or tile units are attached by coating. The configuration of the present invention will be explained below based on the embodiments shown in the drawings. 1 and 2 show a tile panel 1 according to the present invention. As shown in the figure, this tile panel 1 is made by coating a metal plate 2 with an acrylic emulsion-based primer 3 consisting of a main agent and an auxiliary agent, and then applying an adhesive consisting of a main agent and an auxiliary agent onto the primer 3. Agent 4 is being applied. Then, the tiles 5 are arranged and adhered via the adhesive 4. The tiles 5 may be a single unit, or may be a unit in which a predetermined number of tiles are arranged and connected with a predetermined joint interval. Therefore, the primer 3 needs to be able to prevent rust from forming on the surface of the metal plate 2 and to be compatible with the metal plate 2 and the tiles 5. put it here,
Good compatibility means that the adhesive strength between the primer 3, the metal plate 2, and the adhesive 4 is sufficient. Therefore, in the present invention, the above requirements are satisfied by limiting the components and mixing ratio of the primer 3 as follows. That is, Primer 3 is a mixture of a main agent and an auxiliary agent prepared separately, of which the main agent is applied with 100% acrylic emulsion, and the auxiliary agent is applied with 50% acrylic emulsion.
% MDI (isocyanate-based) and 50% toluene. Then, the weight mixing ratio of the main agent and the auxiliary agent is 100:12.8.±1.0. The main agent and the auxiliary agent are mixed at the site where the tile panel 1 is manufactured. The primer 3 having the above structure forms a thin film of the primer 3 on the surface of the metal plate 2 after being applied to the metal plate 2, and prevents the occurrence of rust by blocking contact between the metal plate 2 and air and water. That's what I do. As the primer 3, other solvents (rubber-based) can be used. In addition, the adhesive 4 can sufficiently hold the tile or tile unit after being pasted, and even when the tile or tile unit is installed on site and is pasted to the vertical metal plate 2. It is necessary that there is no slippage. Therefore, in the present invention, the adhesive 4 is configured as follows. That is, the adhesive 4 according to the present invention is a two-component mixed type epoxy adhesive consisting of a main agent and an auxiliary agent, and the main agent and the auxiliary agent are prepared separately and mixed in equal amounts on site. It is something. The components of the main agent and the auxiliary agent are, for the main agent, 15 to 30 wt% of epoxy resin and 85 to 70 wt% of filler. The main components of the above filler are ground calcium carbonate, aluminum hydroxide, etc., and fibrous minerals such as chrysotile and clomidolite minerals, fibrous organic substances such as pulp, or extremely fine particles of amorphous anhydride. It contains silicic acid. This additive is intended to improve the thixotropic properties of the adhesive 4. The fiber length of the above fibrous minerals and fibrous organic substances is 0.05 to 5.
mm is optimal, and the particle size of amorphous silicic anhydride is
Optimal is 0.05-1 μm. Furthermore, the amount of additives is 2 to
It is sufficient if it is 20wt%. The reason why the amount of the additive is limited to this range is that if the amount of the additive is too small, the thixotropic properties of the adhesive 4 will be insufficient, and if the amount of the additive is too large, the adhesive strength and fluidity will be insufficient. be. The adjuvants are: curing agent 5 to 40 wt%, curing accelerator 5 wt% or less, fluidizer 5 wt% or less, filler 90 to 60 wt%. As the curing agent, (poly)amine-based and (poly)amide-based acid anhydrides are suitable. The curing accelerator is used to increase the curing rate, and one that has a high rate of ring-opening polymerization of the epoxy ring may be selected. Glidants also reduce viscosity,
Furthermore, the filler in this adjuvant is the same component as the filler in the main ingredient, and is intended to improve workability, and is intended to achieve the same purpose. Therefore, the explanation here will be omitted. If Adhesive 4 has such components, fine particles of amorphous silicic anhydride, fibrous minerals, and Organic substances are entangled and adhered, and the thixotropic properties of the adhesive 4 are improved. What is thixotropic property?
When stirred or pressed, the gel turns into a fluid sol, and when left alone, it returns to a gel and retains its original shape. The adhesive 4 according to the present invention improves the above-mentioned thixotropic property to prevent tiles or tile units from slipping down immediately after being pasted.
In this case, the deviation is what occurs when a tile or tile unit is attached to a vertical metal plate 2 during on-site construction. Next, the tile units were arranged and pasted on the metal plate 2 via the primer 3 and adhesive 4 described above (“Yes” in Table 1), and the metal plate was coated with only the adhesive 4. The results of the adhesion strength test with the tile unit adhered to the tile unit ("no" in Table 1) will be explained with reference to Table 1. The sample used in the test in Table 1 was metal plate 2.
The size of a single tile in the 300 x 600 mm Elio steel plate tile unit is 100 mm square (including joints).
In Table 1, the pull unit is a waterproof sheet made of synthetic fiber nonwoven fabric and rubberized asphalt compound that is integrated with tiles through special processing. Also, in Table-1,
A unit is simply a tile unit made by connecting tiles with connecting paper. Furthermore, air curing refers to leaving the tile panel in the air for two weeks, and underwater curing refers to leaving the tile panel in the air for one week, and then immersing it in water at 20°C for one week. be.
Hot water curing involves leaving the tile panels in the air for one week, and then immersing them in warm water at 60°C for one week. Furthermore, the variation σ is the variation in adhesive strength when five tiles of each cured tile panel are forcibly peeled off and the adhesive strength is measured. By the way, the measurement method was carried out using a Kenken type adhesive force tester. Moreover, the unit of adhesive strength is Kg/ ^cm2 .

[Table] According to Table 1, tile panels coated with Primer 3 have better adhesive strength than those not coated with Primer 3.
Furthermore, the variation σ in adhesive strength is also small. Therefore, it is clear that this primer 3 is compatible with the metal plate 2 and the adhesive 4, and it is possible to obtain a tile panel 1 having uniform adhesive strength. In short, the primer in the tile panel of the present invention is compatible with the metal plate and adhesive, and forms a thin film on the surface of the metal plate to block contact between the metal plate and air and water, so it can prevent rust. It is possible to prevent the occurrence of In addition, adhesives have excellent thixotropic properties, so
It is possible to prevent tiles from shifting after the tiles or tile units are pasted. As a result, the present invention can provide a completely new tile panel that uses a metal plate as a substrate.
