Description

DETAILED DESCRIPTION OF THE INVENTION 1. Field of the Invention The present invention relates to a method for surface treatment of flaky fibrous covering materials such as calligraphy, painting, and colored fabric.

Conventional technology In recent years, for the purpose of decoration and long-term preservation, it has become common practice to apply surface treatments to flaky fibrous covering materials such as calligraphy and painted fabrics by laminating or coating them to form a transparent hard protective film. Became.

Conventionally, as shown in FIG. 8, for example, as shown in FIG. A thermosetting resin such as resin was applied and cured to form a transparent hard protection [I(3)].

Problems to be Solved by the Invention However, when a thermosetting resin such as an unsaturated polyester resin is applied directly onto a fibrous covering material as in the past,
The thermosetting resin transfers to the fibrous covering material, causing the background pattern on the back side to stand out and causing pigments and dyes to bleed into the background, resulting in a poor finish. Ta.

The present invention aims to solve these problems.

Means for Solving the Problems The present invention provides a method for preventing penetrating into the flaky fibrous covering material (5) from above the flaky fibrous covering material (5) such as calligraphy and paintings adhered to the substrate (6). , and a film-forming agent such as a vinyl acetate adhesive that becomes transparent after curing is applied, and a cured transparent film (9) by the film-forming agent is formed over the entire surface of the fibrous covering material (5). Then, a thermosetting resin such as unsaturated polyester resin is applied to cause a curing reaction, and the fibrous covering material (5
) is characterized in that a transparent hard protective film (15) is formed to protect the material.

The fibrous covering material (5) is added to the flaky fibrous covering material (5).
Since the film-forming agent, such as vinyl acetate adhesive, which does not penetrate into the fibers and becomes transparent after curing, is applied to the front, the film-forming agent does not penetrate into the fibrous covering material (5). It never penetrates. Moreover, after the film forming agent is cured to form the cured transparent film (9), a thermosetting resin such as unsaturated polyester resin is applied to form the transparent hard protective film (15). , the thermosetting resin does not pass through the cured transparency 1it (9) and transfer to the fibrous covering material (5).

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

First, as shown in Figure 2, a thin fibrous covering material (5) such as drawing paper or washi paper with a design (4) drawn with watercolors, crayons, ink, etc., and a wooden substrate such as plywood ( 6) Prepare each of the following.

Then, a vinyl acetate adhesive that is compatible with the wooden substrate (6) is applied to the surface of the wooden substrate (6) to form an adhesive layer (7), and then the fibrous covering material (5) ) on the wooden substrate (6) with the pattern (4) facing up. Then, the wooden substrate (6) and the fibrous covering material' (5) thus stacked are pressed (not shown).
Pressure of 1 to 1.5 t is applied to bond.

Next, the vinyl acetate adhesive mentioned above was diluted twice with fresh water. Prepare dysentery and use the film-forming agent as
As shown in FIG. 1, it is applied to the entire surface of the fibrous covering material (5) using a roller (8a) and allowed to air dry. The film-forming agent may be sprayed with a spray gun. This film-forming agent hardens without penetrating the fibrous covering material (5), becomes completely hardened and transparent.
As shown in the figure, a cured transparent film (9) is formed on the surface of the fibrous covering material (5).

The film forming agent is required to have properties such that it does not penetrate the fibrous covering material (5) and becomes transparent after curing. In addition to the vinyl acetate adhesive described above, gelatin, for example, can be considered as a material having such properties.

In the next step, an affinity agent mixed with an equal amount of a two-component polyurethane sealer is applied onto the cured transparent film (9) using a spray gun, etc., to form a cured transparent film (9) as shown in FIG. An intermediate layer (10) is formed thereon. After the above-mentioned affinity agent is cured to the extent that it does not stick to the tip when touched with a finger, a three-component thermosetting unsaturated polyester resin containing paraffin is added as a thermosetting resin to the intermediate layer (
10) is applied with a brush to cause a curing reaction to form a transparent hard base layer (11). Furthermore, the surface of the hard underlayer (11) thus obtained is polished to an appropriate roughness by using a sander (not shown). This polishing operation results in the removal of paraffin that has separated and floated near the surface of the hard underlayer (11).

The final step is film processing. This film processing is performed as follows. First, an unsaturated polyester resin having the same composition as above was applied to the hard base layer (
11) Pour on top. However, in this case, use one that does not contain paraffin to give the work a glossy shine. Then, as shown in FIG. 5, a pressing member (14) is prepared, in which a film (13) with a bar such as vinyl chloride or cellophane is pasted onto a rectangular frame (12), and the pressing member (14) is It is placed on a wooden substrate (6) and the hard base layer (11) is covered with the film (13). In that case, heat is applied to the front of the film (13) to sufficiently smooth out wrinkles on the surface.

Then, as shown in FIG.
), spread the unsaturated polyester resin evenly over the surface, smooth the surface, and leave the film (13) as it is until the curing reaction is completed. Then, as shown in Figure 7, a hard base layer (11) is formed. The transparent hard protective film (15) formed on the outside of the film (1
3) The back surface shape is transferred to obtain a glossy surface shape. In addition, when a transparent hard protective film (15) without gloss is required, it is sufficient to simply use a matte film (13).

In addition, by double coating the thermosetting resin, that is, the unsaturated polyester resin as in this example, the hard base layer (11) and the transparent hard protective film (15) are laminated, giving a deep appearance. shape can be obtained.

Effects of the Invention As described above, in the present invention, acetic acid that does not penetrate into the fibrous covering material and becomes transparent after curing is applied from above the flaky fibrous covering material such as calligraphy and paintings adhered to the substrate. By applying a film-forming agent such as a vinyl adhesive, the components of the film-forming agent do not penetrate between the fibrous covering materials, and a cured transparent film is formed by the film-forming agent. Since we apply a thermosetting resin such as unsaturated polyester resin to the surface of the board, the background pattern of the board will not stand out, and coloring components such as pigments and dyes will not bleed into the background. This resulted in a good finish.
