A surface treatment for metal, prepared by adding a cationic or nonionic,. urethane, acrylic, epoxy, polyester, or polyamide resin, a resin compound represented by the general formula (I), and a compound of Zr, Ti, V, Mo, W, Mn, or Co to water; a process for surface treatment of metallic substances, and surface-treated metallic substances: (I) [wherein R1 is -CH2-, CH2-NH-CH2-, or -CH=N-CH2-Y is H or a group represented by the general formula (II)-(II) Z is a residue of an aromatic compound or the like; W is H or a group (P) selected from among -CH2X, -CH2NHCH2X, and -CH=NCH2X (wherein X is OH, OR4, halogeno, -N(R5)(R6), or -N+(R7)(R8(R9)A-), with the proviso that the degree of substitution with the group (P) satisfies the relationship: (member of Ps)/(total number of benzene rings and Zs) = 0.2 to 4.0; n is 0 to 10). The surface treatment is free from chromium and can import excellent corrosion resistance, alkali resistance and fingerprinting resistance to metallic substances.
一种金属表面处理剂,通过向水中加入阳离子或非离子、聚氨酯、丙烯酸、环氧、聚酯或聚酰胺树脂、通式(I)代表的树脂化合物和 Zr、Ti、V、Mo、W、Mn 或 Co 的化合物制备;一种金属物质表面处理工艺,以及经表面处理的金属物质:(I) [其中 R1 是-CH2-、CH2-NH-CH2-或-CH=N-CH2-Y 是 H 或通式(II)-(II)代表的基团 Z 是芳香族化合物的残余物或类似物;W 是 H 或选自 -CH2X、-CH2NHCH2X 和 -CH=NCH2X(其中 X 是 OH、OR4、卤素、-N(R5)(R6)或 -N+(R7)(R8(R9)A-)的基团 (P),但与基团 (P) 的取代度必须满足以下关系:(Ps的成员数)/(苯环和Zs的总数) = 0.2至4.0;n为0至10)。表面处理不含铬,具有优异的耐腐蚀性、耐碱性和对金属物质的抗指纹性。
