| titleOfInvention | Surface conditioner and method of surface conditioning |
| abstract | It is an obj ect of the present invention to provide a surface conditioner which can inhibit galvanic corrosion on an aluminum alloy during chemical conversion treatment and can form a sufficient chemical conversion coat when applied to an aluminum alloy and a high tensile strength steel sheet andhas the excellent stability of dispersion in a treatment bath. <??>A surface conditioner, containing zinc phosphate particles and having a pH of 3 to 12, wherein said zinc phosphate particles have D50 of 3 mu m or less and said surface conditioner contains at least one species selected from the group consisting of (1) carboxylate group-containing copolymers obtained by copolymerizing a monomer composition containing at least one species selected from the group consisting of acrylic acid, maleic acid, maleic anhydride, itaconic acid and itaconic anhydride in an amount less than 50% by weight and at least one species selected from the group consisting of a sulfonic acid monomer, styrene, olefin monomers, amino group-containing monomers and polyoxyalkylene derivatives expressed by the following formula (I); <CHEM> wherein Z is a residue of a compound having two hydroxyl groups, AOs are oxyalkylene groups having 2 to 18 carbon atoms, X is an unsaturated hydrocarbon group having 2 to 5 carbon atoms, R<1> is a hydrocarbon group having 1 to 40 carbon atoms, and a and b are identical to or different from each other and integers of 0 to 1000, and satisfy the relationship of a+b ≥ 1 in an amount more than 50% by weight, (2) polyamino acids having a constituent unit expressed by the following formula (II); <CHEM> wherein R<2> and R<3> are identical to or different from each other and are a straight-chain or branched alkyl group having 1 to 22 carbon atoms, a cycloalkyl group having 6 to 22 carbon atoms or an aryl group having 6 to 22 carbon atoms, and said R<2> and said R<3> may have a substituent including heteroatoms, and (3) phosphate esters expressed by the following formula (III) ; <CHEM> wherein R<4> is an alkyl group or an alkyl phenol group having 8 to 30 carbon atoms, and 1 is 0 or 1, m is 1 to 20 and n is 1, 2 or 3, or the following formula (IV); <CHEM> wherein h is an integer of 2 to 24 and i is 1 or 2. |
