Problems solved by technology

Therefore, when such an exterior material is used for a long time, there will be a problem that not only the organic solvent as the electrolyte, but also moisture in the atmosphere will infiltrate into the container, react with the electrolyte to generate hydrofluoric acid, and the hydrofluoric acid will penetrate into the container. The over-lamination film causes peeling between the metal surface and the lamination film, and at the same time causes corrosion to the metal surface
In addition, there is also the following problem: the metal material may be preheated (200~300°C) before lamination, and the effect of heat will cause deterioration of the film and decrease in adhesion

Embodiment 1~32 and comparative example 1~10

[0149] A stainless steel plate (SUS304, plate thickness 0.3 mm) was spray-degreased at 65° C. for 1 minute with a 3% aqueous solution of Fine cleaner E359 (alkali degreasing agent manufactured by Nihon Parkerizing Co., Ltd.), and then washed with water to clean the surface. Next, in order to evaporate the water|moisture content of the surface of a stainless steel plate, it dried with a drier. Utilize the rod coating method that the metal surface treatment agent of the embodiment 1~32 shown in table 1 and table 2 and comparative example 1~10 is coated on the stainless steel plate surface through degreasing cleaning, and in hot air circulation type drying oven at 200 °C for 1 minute to form a surface treatment film with a given film thickness on the surface of the stainless steel plate. On a stainless steel plate with a surface treatment film formed, heat-laminate a polyester film (film thickness 16 μm) at 250°C for 5 seconds (reaching plate temperature is 180°C), and make the s...

Abstract

The invention relates to a metal surface treatment agent used for forming a surface treatment coating. Even if a resin film is laminated onto a substrate surface made from stainless steel, and molding is subsequently carried out, the metal surface treatment agent imparts a high adhesion to the laminate film, so that the laminated film is prevented from peeling and can maintain a stable adhesion over the long term, regardless of exposure to high-boiling gas atmosphere, solvent and acid. The metal surface treatment agent contains a Cr(III) compound (A), and at least one type of compound (B) selected from an inorganic compound (b1), a film-forming inorganic compound (b2) and an organic chelate compound (b3) which can bond to Cr (III) compound (A) to form a film. The organic compound (b1) has film-forming properties and is at least one from an anion compound and a nonionic compound. If the metal Cr equivalent mass of compound Cr (III) compound (A) is set to M, and the mass of compound (B) is set to N, the ratio N / M is set to fall within the range of 0.005 to 1.

Description

technical field [0001] The present invention relates to a metal surface treatment agent for laminated substrates for forming a surface treatment film that can make the surface of a base material made of stainless steel bond with a laminate, and a metal material obtained by using the treatment agent. Adhesion between films or resin coating films is improved. [0002] More specifically, the present invention relates to a metal surface treatment agent for a laminated base and the like for forming a surface treatment film excellent in chemical resistance even when a resin film is laminated on a substrate made of stainless steel. In the case of forming a resin coating film on the surface of the material or on the surface of a base material made of stainless steel, and then performing severe forming processes such as deep drawing, thinning (しごき) or tensioning, it is also possible to impart The laminated film or resin coating film has high adhesion when peeled off, and can maintain ...
