この発明は、赤外線照射等によって被塗物の表面に塗料
を焼付するための焼付塗料の塗装方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a baking paint coating method for baking the paint onto the surface of an object to be coated by infrared irradiation or the like.
従来より、赤外線照射等による被塗物への塗料の焼付が
行われているが、塗装していない裏面に比べて塗装した
表面の熱の吸収率が高いため、焼付時において被塗物に
反り等の変形が発生するという問題があった。Traditionally, paint has been baked onto the object by infrared irradiation, but because the coated surface has a higher heat absorption rate than the unpainted back side, the object may warp during baking. There was a problem that deformations such as the following occurred.
この発明の目的は、塗料の焼付時において被塗物に反り
等の変形が発生するの防止した焼付塗料の塗装方法を提
供することである。SUMMARY OF THE INVENTION An object of the present invention is to provide a method for applying a baking paint that prevents deformation such as warping of an object to be coated during baking of the paint.
この発明の焼付塗料の塗装方法は、被塗物の表面に塗膜
を形成するとともに、その裏面に表面の塗膜と同じ熱吸
収率を有する熱吸収層を形成し、両面を加熱して表面の
塗膜を焼付けるものである。The baking paint coating method of the present invention involves forming a coating film on the surface of the object to be coated, and forming a heat absorption layer on the back side with the same heat absorption rate as the coating film on the surface. The coating film is baked on.
このように、この発明によれば、被塗物の裏面に表面と
同じ熱吸収率を有する熱吸収層を形成したので、被塗物
の表裏面の熱吸収率が同等となり、塗料の焼付時に発生
する被塗物の反り等の変形を確実に防止することができ
る。As described above, according to the present invention, since a heat absorption layer having the same heat absorption rate as the front surface is formed on the back side of the object to be coated, the heat absorption rate on the front and back sides of the object to be coated is the same, and when the paint is baked, It is possible to reliably prevent deformation such as warping of the object to be coated.
実施例
この発明の一実施例を第１図に基づいて説明する。すな
わち、この焼付塗料の塗装方法は、第１図に示すように
、表面に塗膜２を形成した被塗物１の裏面に表面と同じ
熱吸収率を有する熱吸収層３を形成し、被塗物１の両面
を加熱して表面の塗膜２を焼付けるものである。Embodiment An embodiment of the present invention will be explained based on FIG. That is, as shown in FIG. 1, this baking paint coating method involves forming a heat absorbing layer 3 having the same heat absorption rate as the surface on the back side of an object 1 on which a coating film 2 has been formed. Both sides of the coating 1 are heated to bake the coating film 2 on the surface.
前記被塗物ｌは木材、金属等で作ったパネル状のもので
あり、その表面には任意の塗料によって塗膜２が形成さ
れる。一方、被塗物１の裏面に形成される熱吸収層３は
被塗物１の表面に塗布した塗料と同じ色の塗料か、ある
いは同等の熱吸収率を有する異なる色の塗料を塗布して
形成される着色層である。The object 1 to be coated is a panel-shaped object made of wood, metal, etc., and a coating film 2 is formed on its surface with an arbitrary paint. On the other hand, the heat-absorbing layer 3 formed on the back surface of the object 1 to be coated can be formed by applying a paint of the same color as the paint applied to the surface of the object 1, or a paint of a different color having the same heat absorption rate. This is a colored layer that is formed.
このようにして形成した被塗物ｌを、この被塗物１の両
面に配置した赤外線ランプ４によって被塗物１の表裏両
面から赤外線を照射して塗料の焼付を行う。The thus formed object 1 to be coated is irradiated with infrared rays from both the front and back sides of the object 1 by infrared lamps 4 placed on both sides of the object 1 to bake the paint.
このようにして形成された被塗物ｌでは、表裏両面の熱
吸収率が同等となるため塗料の焼付時に被塗物に反り等
の変形が発生するのを防止することができる。In the coated object l formed in this manner, the heat absorption coefficients of both the front and back surfaces are equal, so that deformation such as warping can be prevented from occurring in the coated object during baking of the paint.
なお、焼付は赤外線のほか加熱炉等で行うようにしても
よい。Note that baking may be performed using a heating furnace or the like instead of infrared rays.
この発明の焼付塗料の塗装方法によれば、被塗物の裏面
に表面と同じ熱吸収率を有する熱吸収層を形成したので
、被塗物の表裏面の熱吸収率が同等となり、塗料の焼付
