好ましい。As the synthetic resin used for fixing the fine particles, any resin that forms a transparent synthetic resin layer can be used. For example, it is preferable to use a liquid material such as PvC paste, epoxy resin, polyester resin, or polyurethane resin, which can be primarily solidified by heat or light.

ナイフから吹き出される風で、余分なコーテイング材を
はき除いていく。この方法であれば、表面の凹凸や平滑
面、粗面共、はゾ均一に塗布することができる。In the coating method using an air knife, for example, first,
Pre-coat (rubber roll) enough coating material to fill the gaps between particles on the rough surface, and then use wind from an air knife to remove excess coating material. With this method, it is possible to uniformly coat uneven surfaces, smooth surfaces, and rough surfaces.
しかも、塗布物の移動速度、エアーの風速、エアー吹付
角度や高さを変えてやることによって塗布厚みも変える
ことができる。Moreover, the coating thickness can be changed by changing the moving speed of the coating material, the air velocity, the air blowing angle, and the height.
エアーナイフのスリットの「１１にとくに制限はないが
、約０．０５〜０．５ｍ、好ましくは約０．０８〜０゜
１５ｍｍである。There is no particular limit to the slit 11 of the air knife, but it is approximately 0.05 to 0.5 m, preferably approximately 0.08 to 0.15 mm.
エアーナイフと塗布面の間隔すなわちナイフの高さは８
−〜２５ｍｍが塗むらなく塗れる範囲であり、高さを変
えることにより、塗工厚も変えることが可能である。ま
た、風速は、吹出し口で７０ｍ／ｓｅｅ以上が好ましい
。The distance between the air knife and the coating surface, that is, the height of the knife is 8
- to 25 mm is the range that can be coated without uneven coating, and by changing the height, it is possible to change the coating thickness. Further, the wind speed at the outlet is preferably 70 m/see or higher.
エアーナイフと塗布面の角度（０）は９０°以下。The angle (0) between the air knife and the coating surface is 90° or less.
とくに８５〜７５′、とくに８０°前後が好ましい。Particularly preferred is 85 to 75', particularly around 80°.
直角に風を当てると、塗料の一部が進行方向にも流れる
ことがあり、うまく塗布できない。また、角度を下げて
いくと、風が流れぎみとなり、塗布むらができやすくな
る。If the wind blows at a right angle, some of the paint may flow in the direction of travel, making it difficult to apply the paint properly. Also, as the angle is lowered, the wind tends to flow, making it more likely that uneven coating will occur.
コーテイング材の粘度はエアーナイフとの関連で６００
０ｃｐｓ／２５℃以下、通常５０００ｃｐｓ／２５℃以
下、好ましくは３０００ｃｐｓ／ ２５℃以下、特に好
ましくは１０００ｃｐｓ／ ２５℃以下である。The viscosity of the coating material is 600 in relation to the air knife.
0 cps/25°C or less, usually 5000 cps/25°C or less, preferably 3000 cps/25°C or less, particularly preferably 1000 cps/25°C or less.
このようにすることにより厚さ０．３ｍｍ以下、好まし
くは０．２ｍ以下の薄い均一な厚みの塗膜を形成するこ
とができる。By doing so, a thin and uniform coating film with a thickness of 0.3 mm or less, preferably 0.2 m or less can be formed.

るような粗面部分は塗料かにじんでいる（第３図Ａ）。A sheet in which PVC paste sol 12 is coated on PVC base material 11 and ceramic particles 13 are filled and fixed thereon is heated in an oven (200°C, 3 minutes) to harden it, and then mechanically embossed to create irregularities. I made a certain decorative flooring material 1. In order to coat this surface with the ultraviolet curing resin paint 8, first, the paint is poured onto the sheet surface and pre-coated over the entire surface using the device 2 and the squeezing rubber roll 3. At this point, a thick layer of paint remains in the embossed recesses. In addition, the paint smeared on the rough surface where the particles were exposed (Figure 3A).

By blowing it off, the amount remaining on the surface is applied as a coating material (FIG. 3B). Moreover, even rough surfaces, smooth surfaces, and concave areas could be coated uniformly (50
μ thickness). The blown paint 8' can be deposited on a collection roll 4, scraped off with a doctor knife 6, and collected in a bank 7. In this application, the direction of the wind is opposite to the direction of travel, and the effective blowing angle is 8
0 degrees is good.
