（従来技術）
従来、塗装面の補修は、通常、ペーパー研ぎ工程、コン
パウンド研ぎ工程、及び仕上げ研ぎ工程という３つの工
程によって行われている。(Prior Art) Conventionally, the repair of a painted surface is usually performed through three processes: a paper sanding process, a compound sanding process, and a final sanding process.
ペーパー研ぎ工程は、＃１０００〜２０００の水研ぎペ
ーパーを使用して、塗装面のゴミやボケ、タレの部分を
水研ぎする工程である。The paper sanding process is a process in which dirt, blur, and sagging parts of the painted surface are wet-sanded using wet sanding paper of #1000 to 2000.
コンパウンド研ぎ工程は、粗目研ぎの工程と中目研ぎの
工程とからなり、いずれの工程もエアー式ディスクポリ
ッシャーを使用して行われる。The compound polishing process consists of a coarse-grain polishing process and a medium-grain polishing process, both of which are performed using an air-type disc polisher.
粗目研ざの工程は、研磨材として、例えば■ソーラー製
のラビングコンパウンド＃１００を使用し、ポリッシュ
時間２分、ディスク回転数２０００〜９０００ｒｐｍで
研磨する。この場合のフンパウンド成分の配合例は次の
通りである。In the coarse polishing step, for example, Rubbing Compound #100 manufactured by Solar Co., Ltd. is used as an abrasive, and the polishing time is 2 minutes and the disc rotation speed is 2000 to 9000 rpm. A blending example of the dung powder component in this case is as follows.
次に、中目研ぎの工程は、研磨材として、例えば石原薬

An example of compound formulation in this case is as follows.
そして、仕上げ研ぎ工程は、単一種類の研磨材を使用し
、フインチ径の発泡ウレタンバフを５００〜２０００ｒ
ｐｍで回転させて行う。In the final polishing process, a single type of abrasive is used, and a foamed urethane buff with a finch diameter is applied for 500 to 2000 rpm.
Rotate at pm.
（発明が解決しようとする問題点）
しかし、近年、塗装面の仕上がりが著しく向上する傾向
にあり、この反面において、塗装面にすり傷等が生じた
場合に、従来の補修方法ではこのすり傷等を十分に除去
して元の状態に復元することが困難となっている。特に
、ブラック、ブラウン、グレー等の濃色塗膜はする傷が
目立ち易く、製品の商品価値が低下し易い。(Problem to be solved by the invention) However, in recent years, there has been a tendency for the finish of painted surfaces to improve significantly, and on the other hand, when scratches, etc. occur on painted surfaces, conventional repair methods cannot repair these scratches. It has become difficult to sufficiently remove and restore the original state. In particular, scratches on dark-colored paint films such as black, brown, and gray tend to stand out, which tends to reduce the commercial value of the product.
そこで、本発明の目的は、たとえ高品質の塗装面にすり
傷等が生じてもこれを容易に除去して元の高品質の塗装
面を復元し得るようにした塗装面の補修方法を提供する
ことにある。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for repairing a painted surface that can easily remove scratches or the like even if they occur on a high-quality painted surface and restore the original high-quality painted surface. It's about doing.

いに硬度の異なる、研磨材を混合してなるコンパウンド
を用いて塗装面のバフ研磨を行うようにしである。In order to achieve the purpose described in (Means and effects for solving the problem), the method for repairing painted surfaces of the present invention uses a compound made of a mixture of abrasives having different hardnesses. The painted surface should be buffed.

く削られた塗装面の平滑度を向上させる。When the repair method of the present invention is applied to the above-mentioned final polishing process, the soft abrasives in the repair compound are crushed by the hard abrasives, and the soft abrasives fill in the gaps between the hard abrasives while painting. Buffing of the surface progresses. In addition, hard abrasive materials also collide with each other and part of them breaks, resulting in smaller diameter abrasive materials. The hard abrasive material roughens the paint film. As the polishing progresses, the soft abrasive material becomes even smaller in size and improves the smoothness of the painted surface that has been roughened by the hard abrasive material.

FIG. 3 is a diagram showing the relationship between the center particle diameter of the abrasive and the finish level of the coating surface when an abrasive with a gloss value of 70 is used. From the same figure, the central grain size of the abrasive is 0.5 to 2.0.
It can be seen that the best finish level can be obtained when the gm is within the range.

It is a diagram showing whether the state is changing. FIG. 12 shows the particle size distribution of the abrasive before polishing, and FIG. 13 shows the particle size distribution of the abrasive after polishing.
この粒度分布のデータを得るために次のような実験条件
で塗膜の研磨を行った。In order to obtain data on this particle size distribution, the coating film was polished under the following experimental conditions.
（以下余白）
第１２図と第１３図を比較すると、研磨前には硬い研磨

れぞれ減少していることが解る。(Margins below) Comparing Figures 12 and 13, it can be seen that before polishing, both the hard abrasive material 3a and the soft abrasive material 3b had a center particle size of approximately 0.5 to 2.0 gm, but after polishing, is a hard abrasive material 3a
It can be seen that the center particle size of the soft abrasive material 3b has decreased to about 0.3 to 1.31 Lm, and the center particle size of the soft abrasive material 3b has decreased to about 0.1 to 0.7 pm.

考えられる。As schematically shown in FIGS. 1 to 3, as polishing progresses, the soft abrasive material 3b changes to the hard abrasive material 3a.
This shows that buffing of the painted surface 1 progresses as the soft abrasive material 3b fills the spaces between the hard abrasive materials 3a. In addition, hard abrasive material 3
It can be seen that the pieces a also collide with each other and a part of them breaks, resulting in a smaller diameter abrasive material. The painted surface l is roughened by the hard abrasive material 3a. It is believed that the soft abrasive material 3b becomes smaller in size as the polishing progresses, and improves the smoothness of the painted surface l that has been roughened by the hard abrasive material 3a.
