法に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for drying or baking a paint film, and more specifically, it uses a combination of far-infrared irradiation and heating with combustion hot air. It forms a paint film free of defects such as stains, paint dripping, and foaming, and provides a dried or baked paint film with excellent adhesion to the substrate in a short time. It is also an efficient method that saves heat resources. The present invention relates to a method for drying and baking a coating film.

作シ、この熱風を送風機にて被加熱物へ送シ、被加熱物
と接触させる方法である。(Prior Art) When drying or baking a wet coating film applied to a substrate, a hot air heating oven is generally used as the heating source. That is, this is a method in which gas is combusted to produce hot air, and this hot air is sent to an object to be heated using an air blower and brought into contact with the object to be heated.
この熱風加熱方式は、加熱温度の制御が比較的容易で、
温度分布が平均化しておシ、かつ安定性に優れていると
いう点で一応意義のある方法として認識されている。This hot air heating method is relatively easy to control heating temperature.
It is recognized as a meaningful method because it averages out the temperature distribution and has excellent stability.

せもつものである。However, with these hot air heating methods, especially when the paint is water-based, heating with hot air may cause slight problems in the coating baking oven of sheets or can bodies that are continuously connected using wickets, net conveyors, Binchen conveyors, etc. The structure is such that the amount of hot air cannot be controlled mechanically, and as a result, at normal sheet coating speeds and can manufacturing speeds, water, which is a medium, evaporates all at once, making it difficult to perform proper drying or baking. Furthermore, in order to apply water-based paint using the heating method described above, there is a problem in that the speed of painting and baking must be significantly reduced. In addition, if the above method is to ensure productivity, a drying furnace with a large capacity is required, and the thermal efficiency is low (the effective utilization rate of the heat consumed for heating the heated object is (only 15 to 30% of fuel consumption), which also has the disadvantage of relatively high fuel efficiency.
（発明が解決しようとする問題点）
とくに、最近の塗装工業にあっては、生産のスピードア
ップが要求され、そのためにはオーブンを長大化しなけ
ればならないという問題が生じる。(Problems to be Solved by the Invention) Particularly in the recent painting industry, there is a demand for speeding up production, which creates the problem that ovens must be made longer.
この場合、設備を長大化させずに生産のスピードアップ
を図ろうとすれば、乾燥時間を短縮させるために加熱温
度を上昇させるか、供給する熱風の量を増加させるとい
う方法が考えられる。In this case, in order to speed up production without increasing the length of the equipment, it is possible to raise the heating temperature or increase the amount of hot air supplied in order to shorten the drying time.

除について未だ十分な解決に至っていない。However, when raising the heating temperature, there are naturally restrictions on the temperature depending on the boiling point of the paint constituent solvent (in the case of water-based paints, the main component is water), the melting point and flash point of the material to be heated, etc. However, when increasing the amount of hot air, difficult problems arise such as the object to be heated (mainly metal) being agitated by the strong hot air and being scratched, and the extent to which the heating temperature increases, That is, the temperature-time curve is related to the temperature and the amount of hot air, but a satisfactory solution has not yet been reached regarding the removal of coating film defects during baking.

る。On the other hand, the far-infrared rays emitted from the far-infrared radiator have the property of being directly absorbed by the object to be heated and rapidly heated, so there is no heat loss in the middle as in the case of blowing hot air.
If the wet paint film is irradiated after painting, it will directly act on other organic constituents, mainly water, and the degree of heating will be limited depending on the degree of water content, so there will be no paint film defects and the drying time will be shortened. It has the excellent advantage of being able to shorten the time. On the other hand, this far-infrared ray has the property of traveling in a straight line like light, so if the object to be heated has a complex shape with uneven surfaces, it has the difficulty of uniformly heating the shaded areas. There is.

十分となるためと思われる。この傾向は、塗膜中に顔料
や充填剤が含有されている場合に特に顕著である。Another disadvantage of using far infrared rays to bake the coating is that the adhesion between the cured coating and the metal substrate is lower than when using a hot air heating method. The reason for this is believed to be that heating with far infrared rays insufficiently heats the interface between the metal substrate and the coating film, which is the most important area in terms of adhesion between the coating film and the metal substrate. This tendency is particularly noticeable when pigments or fillers are contained in the coating film.
したがって、本発明の目的は、下地との密着性にすぐれ
た乾燥乃至焼付塗膜を短時間の処理で得ることができる
ということの他に、熱資源の省力化をも達成した効率的
な塗膜の乾燥乃至焼付方法を提供することにある。Therefore, an object of the present invention is to provide an efficient coating film that achieves a dry or baked coating film with excellent adhesion to the substrate in a short processing time, and also saves heat resources. An object of the present invention is to provide a method for drying or baking a film.
本発明の他の目的は、水性塗料を施した缶用素材の塗膜
の乾燥乃至焼付けに特に適した方法を提供するにある。Another object of the present invention is to provide a method particularly suitable for drying or baking a coating film on a can material coated with a water-based paint.
（問題点を解決するための手段）

用することにより、上記課題が達成されることを見出し
た。(Means for Solving the Problems) The present inventors have achieved the above-mentioned problems by using both far-infrared ray heating and combustion hot air heating for drying or baking the retention film (particularly the water-based paint film). I found out that it can be done.

燃焼熱風と接触させることを特徴とする塗膜の乾燥乃至
焼付方法、が扮供される。According to the present invention, a method for drying or baking a wet paint film applied to a substrate is characterized by irradiating far infrared rays using a fuel gas as a heat source and bringing the wet paint film into contact with combustion hot air from the heat source. , is presented.

下同時法と呼ぶ）。In a most preferred embodiment of the present invention, the wet paint film is first irradiated with far infrared rays and then brought into contact with combustion hot air (hereinafter referred to as the sequential method).According to another preferred embodiment, the wet paint film is Far-infrared ray irradiation and contact with combustion hot air are performed simultaneously (hereinafter referred to as the simultaneous method).
（作用）
本発明によると、遠赤外線による照射と遠赤外線輻射の
ための熱源として使用された燃焼熱風による加熱を併用
することによシ、きわめて効率的に塗膜の乾燥乃至焼付
けが達成されるものである。(Function) According to the present invention, drying or baking of the coating film can be achieved extremely efficiently by using both irradiation with far infrared rays and heating with combustion hot air used as a heat source for far infrared rays. It is something.
この方法は、塗料が水性塗料の場合に、よシ効果的な乾

吸収することによるものであり、湿潤塗膜中の水等の溶
媒の蒸発が、熱風加熱の場合に比して極めて短時間のう
ちに行われ、しかも水の蒸発の程度に応じて加熱の程度
も制限されるから塗膜欠陥の無い塗膜が形成される。This method provides highly effective drying and baking when the paint is water-based. The reason for this is that the medium in the paint, water or other solvents, absorbs far infrared rays very efficiently, and the evaporation of water or other solvents in a wet paint film is faster than in the case of hot air heating. This is done in a very short time, and the degree of heating is limited depending on the degree of water evaporation, so a coating film without coating defects is formed.
一方、金属基体と塗膜との界面部分の加熱が遠赤外線照
射のみによる場合には不十分となることは前述したとお

熱が迅速に行われて基体に対する密着性にすぐれた塗膜
が短時間の加熱処理によ多形成されるものである。On the other hand, as mentioned above, heating of the interface between the metal substrate and the coating film by far-infrared irradiation alone would be insufficient, but in the present invention, hot combustion air is applied to the coating film from which the solvent has evaporated. Due to the contact, the area is rapidly heated by heat conduction, and a coating film with excellent adhesion to the substrate is formed in a short heat treatment.
また、被加熱物が三次元上の物体や凹凸のある複雑な形
状の物体である場合にも全体が比較的均一に加熱でき、
陰になる部分の乾燥乃至焼付不良をも解消しうるもので
ある。In addition, even if the object to be heated is a three-dimensional object or an object with a complex shape with uneven surfaces, the entire object can be heated relatively uniformly.
It is also possible to eliminate dryness or poor printing in shaded areas.
