Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、自動車にシーリング材を塗布することより
なる自動車の防錆、防水処理方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for rust-proofing and waterproofing an automobile by applying a sealing material to the automobile.
［従来の技術］および［その解決課題］ 従来より、自動車の鋼板合わせ目部分、鋼板の末端折
り曲げ部分等には防錆、防水処理のため塩化ビニル系シ
ーリング材が広く使用されている。[Related Art] and [Problems to be Solved] Conventionally, vinyl chloride-based sealing materials have been widely used for rustproofing and waterproofing in joints of steel plates of automobiles, bent end portions of steel plates, and the like.
塩化ビニル系シーリング材は、従来、一般に、手作業

わせ目部分等をシーリングし、防錆、防水効果を得てい
る。Conventionally, a vinyl chloride-based sealing material is generally applied by a flow gun method mainly using manual work, is smoothed evenly with a brush, a spatula, and the like, and is cross-linked and cured by passing through a baking and drying furnace. Dry and seal the joints of the steel plate, etc. to obtain rust and waterproof effect.

板の継目等に塗布されるシーリング材もまた、現在塗布

くとも維持しつつ、軽量化することが望まれているのが
現状である。In automobiles, in addition to the maintenance of rust prevention and waterproofness by such a sealing material, reduction in weight is one of extremely important issues. For this reason, the sealing material applied to the seam of the steel plate for rust prevention and waterproofing can also be reduced in weight while at least maintaining various properties such as rust prevention and waterproofing of the currently applied sealing material. What is desired is the current situation.

ような自動化の促進に寄与できるばかりでなく、作業時
間の短縮にもなり、また、次に述べるような重量低減な
どにも大いに寄与できることになる。However, in general, it is difficult to achieve both the reduction in weight and the maintenance of various properties such as rust prevention and waterproofing.In the conventional example, the volume shrinkage of the sealing film before and after baking hardening is large, and a gap is formed in the sealing portion due to the shrinkage. There is. In addition, since the volume shrinkage is large, the method of applying the sealing material also has a problem in that the flow gun must be used, and a spatula must be used after the application. Prevents automation by robots. In order to promote this automation, it is preferable to use airless spraying.Furthermore, such a waterproof and rustproof sealer and an undercoat for ensuring chipping resistance should be applied by airless spraying as much as possible. And if both can be constructed with a lightweight common product, it will not only contribute to the promotion of such automation, but also shorten the work time, and will greatly contribute to the weight reduction as described below. .

大きいことから、防錆、防水性能に対する十分なる信頼
性を確保するためには、シーリング材の塗布量も多くを
必要とし、シーリング材の塗布膜も勢い厚膜とせざるを
えなかった。That is, in the conventional example, as described above, since the volume shrinkage rate is large, in order to ensure sufficient rust prevention and waterproof performance, a large amount of the sealing material is required, and the sealing material is required to have a large amount. The coating film had to be thicker.
本発明はかかる従来例の有する欠点を解消することを
目的としたものである。An object of the present invention is to eliminate the disadvantages of the conventional example.

Developing a sealing material for ultra-low-density vehicles that can contribute to weight reduction of automobiles because it is equal to or more than that and has a low specific gravity,

る。In addition, since the sealing material used in the present invention has a small volume shrinkage and has a waterproof performance equal to or higher than the conventional sealing material even in a thin film than the conventional sealing material, the application method of the sealing material is also applied by a sealing-only gun called a flow gun. After the application, the application by airless spray becomes possible from the conventional method called spatula uniform, and the number of steps is reduced. This also has the effect of facilitating the transfer of the sealing material application process to automation by a robot.
