することができる。Detailed Description of the Invention (,) Object of the Invention (Field of Industrial Application) The method for assembling and adhering automobile body panels of the present invention provides hoods, trunks,
Panels for automobile bodies such as roofs and doors can be easily manufactured using conventional adhesive painting line equipment.
(従来の技術)
従来、たとえばフード、トランク、ルーフ、ドアー等の
自動車車体用のパネル類の組立製作は、一般に0.5〜
1. O■厚さの鋼板のプレス切断加工された外側用鋼
板(以下、「外板」という。)に、補強のために同様に
プレス切断加工された鋼板(以下、「内板」という。」
を内側から自てて、その端部をかしめ、ねじ止め、溶接
又は接着郷によシ固定し、かつ外板の比較的平坦全部分
等の強度不足を補強するために、端部以外の中心部等に
おいても外板と内板とを接着剤により液分して一体化さ
せている。(Prior Art) Conventionally, panels for automobile bodies, such as hoods, trunks, roofs, doors, etc., have generally been assembled and manufactured at a speed of 0.5 to
1. An outer steel plate (hereinafter referred to as the ``outer plate'') that has been press-cut from a steel plate with a thickness of 0.0 cm, and a steel plate that has been press-cut in the same manner for reinforcement (hereinafter referred to as the ``inner plate'').
from the inside, and fix the edges by caulking, screwing, welding, or gluing, and in order to reinforce the lack of strength in all relatively flat parts of the outer skin, In other parts, the outer panel and inner panel are separated and integrated using adhesive.
そして、かかる場合に用いる接着剤としては、従来、合

付炉における140〜200℃の20〜40分間の加熱
により行なわせている。Conventionally, the adhesive used in such cases is a rubber adhesive containing synthetic rubber, a rubber vulcanizing agent, a plasticizer, a filler, etc., and the curing of the adhesive is I?
This is done by heating in the panel painting baking process, that is, heating at 140 to 200° C. for 20 to 40 minutes in a paint baking oven.
しかし、従来の上記の接着剤は、接着強度を高く設計す

止できるが、接着強度が低くすぎて、接着本来の目的、
すなわちツヤネルの補強目的を達成することができ表か
った。However, if the above-mentioned conventional adhesives are designed to have high adhesive strength, distortion will occur in the glossy outer panel due to thermal expansion and contraction during heating and cooling during the paint baking process, and the adhesive strength will be low. Although the above-mentioned distortion can be prevented by designing, the adhesive strength is too low and the original purpose of adhesion is defeated.
In other words, it was possible to achieve the purpose of reinforcing glossy flanges.
前記の問題点を解決する方法として、組立接着に用いた
接着剤を前記の焼付炉に入る前に完全硬化させる方法が
考えられる。たとえば、使用した接着剤を紫外線等の放
射線、超音波又は高周波等を用いて完全に硬化させる方
法、或いは接着剤にウレタン・シリコーン樹脂を用いて

熱性及び耐塗装性等の点において問題があるし、さらに
新たな設備を必要とする等のために、従来の組立接着塗
装ライン設備をそのまま利用することができないなどの
理由から、現実に利用されるに至っていない。One possible solution to the above problem is to completely harden the adhesive used for assembly bonding before entering the baking oven. For example, a method of completely curing the used adhesive using radiation such as ultraviolet rays, ultrasonic waves, or high frequency waves, or a method of using urethane/silicone resin as the adhesive and completely curing it with moisture, etc. However, these methods have problems in terms of the price of the adhesive used, curing speed, heat resistance, paint resistance, etc., and they also require new equipment, so they cannot be used in conventional assembly adhesive painting lines. It has not been put to practical use because the equipment cannot be used as is.
