Problems solved by technology

[0020] To sum up the problems of these prior art, firstly, in the conventional etching method or chemical treatment method, during the processing step, during the necessary cleaning step of the metal material surface after etching or chemical treatment, a large amount of non-recyclable waste is generated. Liquid, so the environmental pressure is high, it is not preferred from the perspective of environmental protection
In addition, with the increase in the number of steps such as cleaning steps, the preparation process becomes complicated and the productivity decreases
Especially in the chemical treatment method, a certain degree of reaction time is required, so the steps th

Example Embodiment

[0264] (Example 1)

[0265] Prepared containing 0.2% by mass of gallic acid monohydrate as compound (A), 30% by mass of acrylonitrile-butadiene-styrene rubber as elastomer (B), and 0.5% by mass of metavanadic acid as oxidant (C) An aqueous solution of ammonium (V) yields a substrate treatment agent (Ia). Elastomer (B) uses an aqueous dispersion of acrylonitrile-butadiene-styrene rubber having carboxyl groups and methylol groups (solid content concentration: 47%, pH: 8, viscosity: 45 cP, Tg: 18°C, specific gravity: 1.01, containing anionic surfactant), adjusted to the content of the elastomer (B) in the aqueous solution.

[0266] A surface treatment with a base treatment agent (I-a) (temperature: 25°C) applied to the surface of the copper foil by bar coating, and then heated and dried (temperature: 100°C) to have a film thickness of 2.5 μm.

Example Embodiment

[0267] (Example 2)

[0268] Prepared containing 0.2% by mass of phloroglucinol (anhydrous) as compound (A), 30% by mass of acrylonitrile-butadiene-styrene rubber as elastomer (B), and 0.5% by mass as oxidant (C) An aqueous solution of ammonium metavanadate (V) yields a substrate treatment agent (Ib). As the elastomer (B), the same water dispersion as in Example 1 was used, and the content was adjusted.

[0269] The surface treatment was performed by applying a base treatment agent (I-b) (temperature: 25°C) to the surface of the copper foil by bar coating, heating and drying (temperature: 100°C), and then having a film thickness of 2.5 μm.

Abstract

Disclosed is a low-cost base processing agent for metal materials, which enables to improve adhesion, particularly adhesion at high temperatures between a metal material and a resin such as a prepreg without roughening the metal material surface. This base processing agent for metal materials does not use a substance such as hexavalent chromium which can be a cause for environmental contamination, and places little burden on the environment. Also disclosed is an environmentally advantageous method for processing a base for a metal material, which uses such a base processing agent and has excellent productivity. Further disclosed are a metal material having a base-processed coating film which is obtained by the base processing method, and a laminated member. Specifically disclosed is a base processing agent for metal materials, which contains at least one compound (A) and at least one elastomer (B). The at least one compound (A) is selected from the group consisting of compounds (A-1) having one or more benzene nuclei and two or more functional groups selected from the group consisting of a hydroxy group, a carboxy group and an amino group and directly bonded to a carbon atom of the benzene nucleus, and thiourea derivatives (A-2).

Description

technical field [0001] The present invention relates to a metal material surface treatment agent for forming a surface treatment film on the surface of a metal material, a metal material surface treatment method using the metal material surface treatment agent, a metal material with a surface treatment film, and a laminated part. Background technique [0002] Various metal materials are used in industrial products, and in addition to corrosion resistance and adhesion, various surface treatments are carried out to impart functions such as heat resistance, hydrophilicity, and sliding properties. [0003] Conventionally, in order to improve the adhesiveness between a metal material and a resin, a method of mechanically roughening the surface of a metal base material by sandblasting or the like to form a so-called anchor recess (anchor) has conventionally been employed. [0004] However, the above-mentioned mechanical processing is generally poor in productivity and tends to be ...
