【発明の詳細な説明】 （産業上の利用分野） 本発明は、円柱又は円筒形状からなる成形物の表面に皮
膜を成形する方法に関する。TECHNICAL FIELD The present invention relates to a method for forming a film on the surface of a molded article having a cylindrical shape or a cylindrical shape.
（従来の技術） 金属ゴムあるいはプラスチックからなる各種形状の成形

ディッピングコート法が用いられている。(Prior Art) As a conventional method for forming a film on the surface of a molded article of various shapes made of metal rubber or plastic, there are a spray coating method in which a film-forming liquid raw material is sprayed on the surface of the molded article, and a molded article by a roller. A roll coating method of applying a film-forming liquid raw material on the surface and a dipping coating method of immersing a molded product in the film-forming liquid raw material to adhere the film-forming liquid raw material to the surface of the molded product are used.

その上前記従来技術の共通の問題として、均一且つ正確
な厚みの皮膜を得ることが難しかったのである。However, the above conventional method has the following problems. That is, although the spray coating method is suitable for forming an extremely thin film, it is not preferable for forming a thick film because the film forming liquid raw material is liable to sag and the appearance of the film surface is impaired. There is a problem that many liquid materials are wasted because they are scattered around, and the roll coating method is suitable for forming a film on a flat surface but is not preferable for forming a film on a curved surface. The ipping coating method has a problem that when the molded product is taken out from the film-forming liquid material, the material is easily dripping and the appearance of the film surface is impaired.
Moreover, it is difficult to obtain a film having a uniform and accurate thickness, which is a common problem of the above-mentioned conventional techniques.

The molded article is arranged so as to be separated from the surface by a predetermined distance, and is horizontally moved from one end direction to the other end direction of the molded article, and further,
A liquid raw material comprising a curable liquid rubber raw material for forming a film or a resin raw material is supplied to the raw material supply pool, and the liquid raw material is spirally adhered to the surface of the molded product so as to have a constant thickness to form a liquid coating. The formed product is rotated until the liquid film is dried and cured, and the viscosity of the liquid raw material is 30 to 1
It is 600 poise, and the peripheral speed of the film formation surface is 5-50 m /
And the moving speed of the raw material supply pool is 0.4
It is characterized by being ~ 2.5 mm / revolution.

で乾燥硬化して硬化皮膜となる。(Function) A liquid film formed by adhering to a surface of a molded product having a cylindrical shape or a cylindrical shape with a constant thickness has a relatively high viscosity because the film-forming liquid raw material constituting the liquid film has a relatively high viscosity. The surface of the liquid film is maintained in a uniform mirror surface state by being rotated without scattering from the above, and after a predetermined time as it is, it is dried and cured in that state, that is, the surface is a uniform mirror surface state, to form a cured film.

The pool 14 adheres to the surface of the molded product with a constant and accurate thickness regulated by the distance between the pool 14 and the surface of the molded product 10.
And the movement of the nozzle 16 forms a liquid film 20 covering the outer peripheral surface of the molded product 10. Since the surface of the liquid film 20 is affected by the shape of the rear end 22 of the pool 14 and the positional relationship with the surface of the molding die 10, it is necessary to keep the portion of the rear end 22 facing the surface of the molded product 10 constant. .

力により飛散するのが防止される。As the film-forming liquid raw material, liquid silicone rubber, latex, urethane elastomer, paint and the like having a relatively high viscosity in liquid or paste form are used. Then, the rotational speed of the molded product 10 is determined according to the viscosity, and the film-forming liquid raw material on the surface of the molded product is prevented from scattering due to centrifugal force during the rotation of the molded product 10.
