The conventional Eucalyptus description is shown in the first figure of the traditional method of manufacturing a resin film-coated metal wrench that bends to a fusion tube. According to the first figure, the metal plate 1 is first plated with rhenium or tin 5 on a rain surface and then subjected to a chemical conversion treatment 4. This final metal plate is printed or coated with a coating material 7 and then, the entire area is covered with a strip of the resin film 2 except for the area to be welded. As described above, a metal such as tin or nickel is welded to the metal plate by plating the entire surface of the metal plate. However, because the metal is applied to an area that does not need to be welded, that is, the area is printed or covered with the resin mold, it is obvious that the waste of metal amount causes an increase in manufacturing costs. In addition, when a resin mold-coated metal sheet conventionally used for welding cylinders is manufactured in a factory, the plating work is first applied to the plating line and then, the resin mold coating is performed on the superposition line so that all manufacturing processes are complicated and Reduced productivity. In particular, in the case of a resin film-coated metal plate for a three-layer can, an additional can-making device conventionally used for the conventional rain-layer can is required. In addition, expensive additives are used to determine thermal adhesion and processability, increasing production costs. 0 This paper size is applicable to China National Standard (CNS) A4 specifications (210 X 297 " " mm) -------- ---- Zhan -------- ^ --------- i.

Description of the invention \ +) For metal plate 1, black steel plate or cold-rolled plate suitable for tin plating does not require pre-treatment or traditional degreasing or pickling after use in order to improve its adhesion. (Please read the precautions on the back before filling this page) rY ± 0 If the adhesion condition changes with the type of resin film and the use of the adhesive, the black steel plate or cold rolled plate is not used, but it can be used in a resin Membrane 2 was treated frontally before coating. For example, when the metal plate is heated at a high temperature for a while, an oxide layer will be formed on the metal surface, resulting in reduced adhesion or discoloration between the metal plate and the resin film occurring on the surface of the metal plate. In these cases, it is possible to prevent the metal plate from fading or deterioration of adhesion, by electrically or chemically forming a chemical conversion coating 4, such as a chromate coating or a phosphite coating. The resin film is as shown in Figures 4, 5, 8, and 9. The composition of the chromate coating can be immersed in the metal plate in sodium or potassium dichromate solution or anhydrous chromate solution for 2 to 30 seconds. Electrically, the chromate coating was formed by performing electroplating in a sodium dichromate solution at a pH of 2.5 to 5.5 at 2 to 8 A / dm2 for 0.5 to 3 seconds. For phosphate coatings, immersion or plating is performed in a phosphate solution. According to the present invention, the phosphate solution is selected from a group of solutions including iron phosphate solution, manganese phosphate solution * zinc phosphate solution, nickel phosphate solution, calcium phosphate solution, ammonium phosphate solution and mixtures. Resin film can be coated with metal. It can be heated from 100 to 280t on the single or double-sided or cold-rolled sheet of black steel plate with resin-coated slat. The cans are welded by laminating rollers and by quenching the board. 0 This paper size is applicable to China National Standard (CNS) A4 (210 X 29f mm) 520323 A7 _B7_ 5. Description of the invention (0 If necessary, the original heating can be followed Second heating and then, by hardening or slow cooling, in order to ensure that the resin film and the metal plate are sufficiently attached (please read the precautions on the back before filling in this page) There is ochre 0 The metal plate can be heated by induction heating Coils or rollers or hot ovens or resistance heating are used. Usually, this second heating is performed at 120-300 U for 2-30 seconds. For quenching, water is widely and conveniently used. However, oil can be used to Instead of water. In water-cooled form, the cooling water preferably rises and falls from about 15 to 6 CTC in terms of temperature. Depending on the type of resin film and adhesive where slow cooling is required, the metal plate is cooled in air. Resin film 2, The advantage lies in the flavor and odor of the contents in the storage tank, and the adhesion and program adhesion to the metal plate. Examples of the resin film include polyolefin, polypropylene, polyester, nylon resin films and mixtures. Alternatively, in The improvement of the resin film may allow to improve the thermal adhesion of the resin film. For example, in order to improve the thermal adhesion of the polyester resin film, its terephthalic acid may be replaced with 10% to 70% by weight of isophthalic acid. , Succinic acid, azelaic acid, adipic acid, i, 4-cyclohexane, dicarboxylic acid, trimellitic anhydride and mixtures. For polyolefin resin films, acid modified polyolefin resins including carboxylic acid groups or anhydrides To improve its adhesion. As shown in the third, fifth, seventh, and ninth figures, it is possible to economically manufacture the resin film-coated metal plate by placing the adhesion layer 3 rather than using the thermal adhesion film. The adhesion layer is made of Contains 20-30¾ crystalline amorphous polyester, epoxy resin, copolyester or acid modified polyolefin, copolyester and the mixture.

Description of the invention (L) Nickel and / or tin are electroplated in a common manner in the welded uncoated area 6, to increase its corrosion resistance and weldability. When nickel is used alone, its deposition amount is from 0.2 to 2.0 g / m2. When tin is used alone, its deposition amount is from 0.2 to 2.0g / m2. When electroplating is performed using nickel and tin, nickel and tin can be deposited at 40-500 mg / n ^ and 0.2-2.0 g / m & If the time is not enough from the manufacture of resin-coated metal plates to welding or when high-speed welding is not used, electroplating is not required here to improve corrosion resistance and weldability. In this example, chromate coating or phosphate The coating film may be formed on the metal surface before the resin film is coated. The printing layer 7 can be inserted between the metal plate 1 and the resin film 2. Alternatively, the printing layer 7 may be inserted between the adhesive 3 and the resin film 3 or between the resin film 2 and the chemical conversion coating film 4.

Description of the invention (/ c0 can device. Except for the welding area 6, the coating of the resin film printing strip on the entire surface of the metal plate eliminates the need for an individual printing process after the can is made, reducing the manufacturing process and the production cost. In addition Because electroplating is not necessary in the area covered with the resin film, this area is also the non-welded area, and waste of nickel or tin is prevented, due to electroplating in the unnecessary area, which is the welding area 6, so that The production cost can be reduced. Moreover, the present invention leads to improved production, by simplifying the manufacturing process and Corrosion, film adhesion and weldability. The present invention has been described in the form of illustrations, and it can be understood that the terminology used is to describe rather than limit the present invention.
