Embodiment

[0121] Hereinafter, the present invention will be described in more detail with reference to examples. In addition, "part" and "%" represent "part by mass" and "% by mass", respectively.

[0122]

[0123] [Titanium-containing aqueous solution (A 1 ) preparation]

preparation example D-1

[0125] In a mixture of 10 parts of 30% hydrogen peroxide water and 100 parts of deionized water, a mixture of 10 parts of titanium tetraisopropoxide and 10 parts of isopropanol was added dropwise while stirring at 20° C. for 1 hour. Then, it was aged at 25°C for 2 hours to obtain a transparent, slightly yellowish, and slightly viscous aqueous solution of peroxotitanic acid (a 1 ) Titanium-containing aqueous solution (A 1 -1). Aqueous solution containing titanium (A 1 Converted TiO in -1) 2 The concentration is 2%.

preparation example D-2

[0127] Except using an equivalent amount of tetra-n-butoxytitanium instead of tetraisopropoxytitanium, operate in the same way as Preparation Example D-1 to obtain a titanium-containing aqueous solution (A 1 -2). Aqueous solution containing titanium (A 1 Converted TiO in -2) 2 The concentration is 2%.

Abstract

The invention provides a composition for metallic surface treatment which is characterized by comprising following components (A) to (C): (A) an aqueous solution obtained by mixing at least one titanium compound selecting from water weakened titanium compound, the condensate of water weakened titanium compound, titanium hydroxide and the condensate of titanium hydroxide with hydrogen peroxide solution(A2), or vanadate peroxide solution (A2); (B) organic phosphate compound; and (C) condensation product of amino silane (c1) and multi-silyl-functional silanes (c2). The composition for metallic surface treatment can form surface treatment envelope which is excellent for storage and has excellent corrosion resistance performance. The adhesive property of a film subjected to a post coating process is good.

Description

technical field [0001] The present invention relates to a metal surface treatment composition and a metal substrate having a surface treatment film. Background technique [0002] Conventionally, in order to improve the corrosion resistance of metal surfaces, chromate treatment and phosphate treatment are generally performed as surface treatments. However, in recent years, the toxicity of chromium is becoming a social problem. The surface treatment method using chromate has the following problems: the problem of chromate fume scattering during the treatment process, the cost of wastewater treatment facilities, and the problem caused by the dissolution of chromic acid from the chemical conversion treatment film. Wait. In addition, hexavalent chromium compounds are designated as human carcinogens by various official organizations represented by IARC (International Agency for Research on Cancer Review), and are extremely harmful substances. [0003] In addition, in order to i...
