The base sheet 16 of the transfer sheet is provided with a release layer 17, the same picture layer 14 as the decorative plate, and an adhesive layer 18.
本発明の補修方法の補修工程の一例を図３に示す。
化粧板上に補修用ベースコート層１９をハケ等により絵柄の抜けた部分に塗布し、表面が乾燥しないうちに補修用転写シートを重ね合わせ、ゴムローラ等によりエアー抜きを行ない、常温乾燥後転写シートの基体シートを剥離し、表面にハケ等により表面保護層を塗布し、再度常温乾燥する。
An example of the repair process of the repair method of the present invention is shown in FIG.
The repair
補修用ベースコート層１９としては、補修用ベースコート層が第一のベースコートと同じ種類又は、油性アクリル、油性アクリルウレタン、油性ウレタン樹脂を使うことができる。
As the repair
また、基材層の中まで達する傷を補修する場合は、市販されたパテで傷を埋めたあとパテ表面に直接絵柄を転写するか、必要に応じて補修用ベースコートを塗布してから転写する方法もある。 Also, when repairing a wound that reaches the base layer, the pattern is transferred directly to the surface of the putty after filling the wound with a commercially available putty, or transferred after applying a repair base coat as necessary. There is also a method.
化粧板の基材として厚み１５ミリの窯業系凹凸基材を用い、これにシーラーとしてウレタン樹脂系シーラーを施したあと、ベースコート層として酸化チタンの入った二液ウレタン樹脂系塗料（大日本塗料（株）製：「Ｖトップ」）を用い、これで乾燥後厚さ５０ｇ／ｍ2 とした後、１２０℃で８分乾燥して基材温度を６０℃にした。 A ceramic-type uneven substrate with a thickness of 15 mm is used as the base of the decorative plate, and after applying a urethane resin sealer as a sealer, a two-component urethane resin paint containing titanium oxide as a base coat layer (Dainippon Paint ( Manufactured by “V Top”), and after drying to a thickness of 50 g / m 2 , the substrate was dried at 120 ° C. for 8 minutes to a substrate temperature of 60 ° C.
次に、転写シートの基体シートとして塩化ビニル樹脂（可塑剤８％）シート（８０μｍ）を用い、これにポリビニルブチラール樹脂系インキ（着色顔料（フタロシアニンブルー）、酸化鉄系顔料の茶、黄土、体質顔料（硫酸バリウム）、溶剤）で絵柄層を印刷し、さらに（ポリビニルブチラール樹脂バインダー、体質顔料（硫酸バリウム）、溶剤）からなる接着層を設けて転写シートとした。
Next, a vinyl chloride resin (
この転写シートの一部の絵柄層を除去して、前記化粧板の基材のベースコート層と貼り合わせ、ゴム硬度４０°の１６０℃に加熱したゴムロールで線圧２０ｋｇf/ｃｍ、ライン速度２０ｍ／ｍｉｎで絵柄層を転写した。この後、転写シートの基体シートを剥離して二液硬化型フッ素樹脂透明保護層（大日本塗料（株）製：「Ｖフロン＃７００」）を塗装して一部絵柄層のない化粧板を得た。 A part of the pattern layer of the transfer sheet is removed and bonded to the base coat layer of the base material of the decorative board, and a rubber roll heated to 160 ° C. with a rubber hardness of 40 ° is subjected to a linear pressure of 20 kgf / cm and a line speed of 20 m / min. I transferred the pattern layer. Thereafter, the base sheet of the transfer sheet is peeled off and a two-component curable fluororesin transparent protective layer (Dainippon Paint Co., Ltd .: “V Freon # 700”) is applied to make a decorative board partially free of pattern Obtained.
この絵柄層のない部分にベースコート層に用いた樹脂と同様の樹脂を塗布し、同じ絵柄の転写シートを貼り合わせ、ハンドローラーでエアーを抜いたあと、約２０℃の気温中で１時間硬化させ、基体シートを剥がし絵柄を転写した。これを２４時間約２０℃の気温中で硬化させたあと、二液硬化型フッ素樹脂透明保護層（大日本塗料（株）製：「Ｖフロン＃７００」）を刷毛で塗り約２０℃の気温中で７日間硬化させ補修した。得られた化粧板は、一様の絵柄を有し、跡がほとんど区別できないほどに補修できたものとなった。 Apply the same resin as the resin used for the base coat layer to the part without the pattern layer, and paste the transfer sheet with the same pattern together. After removing the air with a hand roller, cure it at about 20 ° C for 1 hour. The base sheet was peeled off to transfer the pattern. After curing for 24 hours in an air temperature of about 20 ° C., a two-component curable fluororesin transparent protective layer (Dainippon Paint Co., Ltd .: “V Freon # 700”) is applied with a brush and air temperature is about 20 ° C. It was cured and repaired for 7 days. The obtained decorative board had a uniform pattern and was able to be repaired so that the traces could hardly be distinguished.
実施例１の絵柄層のない化粧板に、絵柄層のない部分に傷を設け、ここにプライマー（オート化学工業（株）製）をハケで塗布して、常温℃３０分乾燥したあと一液湿気硬化型ウレタン弾性パテ（オート化学工業（株）製「オートアドハー３０００」）にて傷を埋め、その後は実施例１と同様にして絵柄を転写して表面保護層を得て補修した。得られた化粧板は、一様の絵柄を有し、跡がほとんど区別できないほどに補修できたものとなった。 The decorative board without the pattern layer of Example 1 was scratched on the part without the pattern layer, and a primer (manufactured by Auto Chemical Industry Co., Ltd.) was applied with a brush, dried at room temperature for 30 minutes, and then one liquid. The wound was filled with a moisture-curing urethane elastic putty (“Auto Adher 3000” manufactured by Auto Chemical Industry Co., Ltd.), and then the pattern was transferred in the same manner as in Example 1 to obtain a surface protective layer for repair. The obtained decorative board had a uniform pattern and was able to be repaired so that the traces could hardly be distinguished.
表面のウレタン樹脂透明保護層が劣化して白化した化粧コンクリートブロックの全面にウレタン樹脂系ベースコート（日本ペイント（株）製：「ルリール」）をハンドローラーにて塗布したあと、同一柄の転写紙を請求項１の条件で転写して、表面保護層を得て補修した。この結果、サンシャインウェザメター（スガ試験機（株）製）３０００時間（ＪＩＳ Ｋ ５４００）しても変色やクラックのない補修した化粧板を得た。
After applying a urethane resin base coat (Nippon Paint Co., Ltd .: “Lulile”) to the entire surface of the decorative concrete block, which has been whitened due to deterioration of the transparent protective layer of urethane resin on the surface, transfer paper with the same pattern is applied. Transfer was performed under the conditions of
以上に示したように、本発明の化粧板の補修方法により、絵柄のみの傷でも、基材の中まで傷の入った化粧板でも補修が可能であり、転写によることで、表面保護層の有無、化粧表面の凹凸に関係なく、同じ絵柄で補修できる。また、補修用ベースコート層に用いる材料を限定することでより丈夫な表面となる。これにより、化粧板の表面保護層が劣化して白化したり、基材のアルカリが表面に析出してエフロレッセンス（ｅｆｌｌｏｒｅｓｃｅｎｃｅ、風化）を生じたり、絵柄や塗料の顔料が退色したような化粧板の表面を補修することも可能となる。 As described above, the decorative plate repair method of the present invention can repair only a pattern scratch or a decorative plate with scratches in the base material. It can be repaired with the same pattern regardless of the presence or absence and unevenness of the makeup surface. Further, by limiting the material used for the base coat layer for repair, a more durable surface can be obtained. As a result, the surface protective layer of the decorative plate is deteriorated and whitened, the alkali of the base material is deposited on the surface to cause efflorescence (weathering), or the decorative plate is discolored from the pattern or paint pigment. It is also possible to repair the surface.
