JPH0730636B2 - Reinforcement, prevention of fall, and beautification of the wall surface of aged tiles using patterned printing paper - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of Invention] <Industrial field of application>
It is related to beautification, and it is possible to form a variety of patterns with rich individuality compared to commonly used mortar coating, reinforcing resin coating, etc., and weather resistance, impact strength, etc. It is a proposal for a method that outperforms the method.

<Prior Art> The applicant of the present invention has previously disclosed that the Japanese Patent Laid-Open Nos. 63-197765 and 63-
As proposed in No. 300170, etc., we have proposed methods for reinforcing the wall surface of the tiles over time, and beautifying the fall prevention.However, these past techniques achieved the desired purposes for reinforcement and fall prevention. With regard to beautification, it was difficult to develop a variety of products in accordance with the diversification of needs, and it was inevitable that one-sided reproach was unavoidable.

<Problems to be Solved by the Invention> The applicant of the present invention continues to earnestly research after the previous proposal, and the conventional method has a poor design of the outer wall surface, and the various patterns required in accordance with the diversification of needs. In view of the fact that it was impossible to realize the present invention, as a result of earnest research, the present invention in which decorative printing paper was additionally applied to the existing technology was reached.

[Structure of the Invention] <Means for Solving Problems> In the present application, as described in the claims, the time-lapsed tile-constructed wall surface is coated with a primer and then subjected to a base treatment. , Coat the surface with unsaturated polyester resin. As the curing agent, curing accelerator and the like used in combination with the unsaturated polyester resin, those usually used in the FRP production may be selected and used.

A multicolor printing paper on which an arbitrary pattern is printed is stuck and fixed on the polyester resin coated surface. Natural or synthetic pulp paper is used as the base paper of this printing paper, but glass paper may also be used. The print pattern is arbitrary, but a stone pattern, a tile pattern, or the like is preferable from the viewpoint of the outer wall. Since the pattern is mainly produced by gravure printing, the pattern, color tone, etc. can be varied and various developments are possible.

Further, a sheet (hereinafter referred to as a glass sheet) in which a chopped strand mat of glass fiber and a glass woven cloth are adhered and laminated in advance is placed on the surface of this decorative printing paper, and an unsaturated polyester resin is applied to the surface of the sheet, and the glass sheet is formed. Penetrate to the decorative printing paper layer through and integrate,
Form a strong FRP layer.

Here, the reason why we used a laminated product of glass fiber chopped strand mat and glass woven cloth is that the adoption of this composite sheet eliminates the unsightly point that the glass fibers scattered in FRP are seen through. This is because the decorative printing layer can be seen through as a three-dimensional and deep one.

In addition, the FRP layer is formed not only on one side of the construction surface but also from one side to the adjacent surface that is in contact with the right angle, by applying the decorative printing paper and the glass sheet, and applying the unsaturated polyester resin on the surface. It is also possible to construct it, and in some cases it is possible to form even the uneven surface in a continuous manner, not only improving the efficiency of the work, but by doing so, the intrusion of rainwater from the end can be completely sealed. is there.

By coating the surface of the FRP layer thus formed with the fluorine resin paint, acrylic silicone paint, etc., which are currently considered to have the best weather resistance, the aged wall surface of aged tiles will be beautiful. The purpose of the recycled tile surface and the reinforcement of the old tile surface and the prevention of falling are also achieved, and it is possible to prevent the life damage due to the falling of the tile wall surface, which is frequently seen on newspapers recently.

[Example 1] After cleaning the tiled wall surface that has been aged on the outer wall of the building and has deteriorated over time, a urethane sealer (made by Dainippon Paint (Wall)) is applied to the surface of the building wall for surface treatment. did.

Then, after the sealant is almost dried, unsaturated polyester resin (Epolac N manufactured by Nippon Shokubai Kagaku Kogyo Co., Ltd.)
-350) is applied to the surface, and a decorative printing paper on which the surface of 80 g / m ² unbleached base paper is printed with a gravure printing machine using a three-color stone pattern is placed, and the polyester resin is sprayed on the surface,
Place a surface mat (30P) lined with chopped strand mat (# 380) on it and smooth it sufficiently, and then 600g (m ^It was painted at a ratio of ² ), and the desired exterior wall was obtained. This outer wall is as aesthetically pleasing as an old tile surface, and it is estimated from the data of basic tests that it will remain the same for more than 10 years.

[Example 2] After cleaning the tiled wall surface that has been aged on the outer wall of the building and has deteriorated over time, an epoxy sealer (manufactured by Dainippon Paint Co., Ltd.) is applied to the surface to remove old joints. As well as filling, the surface was painted and flattened.

Then, the drying and curing of the sealer was allowed to proceed, and the unsaturated polyester resin (Nippon Shokubai Kagaku Kogyo Co., Ltd. Epolak N
-500) is applied, and the surface is exposed to 120 g / m ² of exposed atoms,
A surface mat lined with a four-color gravure printing machine on which a pattern printing paper with tile pattern printing with joints is applied, the polyester resin is sprayed onto the decorative surface, and lined with a chopped strand mat (# 380) ( 30
P) was placed and smoothed sufficiently, and then the surface was coated with a fluorine resin paint at a rate of 600 g / m ² to obtain a beautiful decorative surface with a tile pattern.

Claims (1)

[Claims] 1. A decorative surface is formed by a procedure from the following on a tile construction wall surface on which a defect may appear or a defect may appear due to the passage of time after construction. Tile wall reinforcement, fall prevention and beautification methods. Over time, paint a primer on the surface of a tiled wall surface, paint an unsaturated polyester resin on the surface, and affix a pattern-printing paper to the coated surface, and use a glass fiber chopped strand mat on the surface of the pattern-printing paper. After placing the mat to which the woven cloth is adhered in advance, apply unsaturated polyester resin on the surface, and through the glass mat and the pattern printing paper, infiltrate and integrate the unsaturated polyester resin layer of the procedure, and then the surface Fluorine resin paint or acrylic silicone resin paint is applied to and cured.
