Abstract

The invention discloses a passivant for a high-wear-resistant aluminum alloy. The passivant comprises, in weight, 1-5 parts of cerium chloride, 5-15 parts of N-phenyl-2-naphthylamine, 3-9 parts of seconary alkane sulphonate sodium, 10-20 parts of vinyl trimethoxy silane, 2-8 parts of hexafluorozirconic acids, 1-10 parts of succinic acids, 1-5 parts of barium metaborate, 4-8 parts of hexamethylenetetramine, 1-5 parts of silicon aluminum powder, 0.2-0.8 part of chromium sulfate, 3-7 parts of wear-resistant materials, 10-30 parts of dihexylamine, 2-8 parts of sec-butyl acetate, 2-5 parts of accelerants, 1-4 parts of magnesium acetate and 40-75 parts of water. The invention further discloses a preparation method of the passivant for the high-wear-resistant aluminum alloy. The passivant has excellent rust protection performance, wear resistance, corrosion resistance and anti-cracking performance and is high in passivation efficiency, short in passivation time, a passivation film can be formed on the surface of the aluminum alloy rapidly, and the film layer is uniform and dense and good in surface smooth degree.

Description

technical field [0001] The invention relates to the field of passivators, in particular to a passivator for high wear-resistant aluminum alloys and a preparation method thereof. Background technique [0002] Passivation is a method to transform the metal surface into a state that is not easily oxidized, and to delay the corrosion rate of the metal. In addition, the phenomenon of an active metal or alloy in which the chemical activity is greatly reduced and becomes a noble metal state is also called passivation. [0003] In the prior art, although the passivating agent used for aluminum alloy has a certain anti-rust effect, but other properties such as wear resistance are poor, and it is increasingly unable to meet the market demand. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present invention proposes a passivator for high wear-resistant aluminum alloys and a preparation method thereof, which has excellent...
