Abstract

The invention relates to a non-chrome passivating agent for steel, zinc plates, aluminum and aluminum alloy pieces, zinc and zinc alloy, which consists of the following materials in percentage by mass: 15 to 35 percent of amino propyl formate resin, 2.0 to 4.0 percent of r-mercaptopropyltrimethoxysilane, 0.1 to 0.5 percent of fluorozirconate, 0.5 to 1.0 percent of acetic acid, 8.0 to 10.0 percent of glycerol silane ether, 0.05 to 0.10 percent of ammonium dihydrogen phosphate, 1.0 to 3.0 percent of butyl cellusolve, 3.0 to 8.0 percent of polyoxyethylene, 0.1 to 0.5 percent of organic lanthanide compound, 0.01 to 0.10 percent of polyoxyethylene polyoxypropylene ether, and the balance of pure water. The non-chrome passivating agent has the advantage that the non-chrome passivating agent is a surfactant with non-nickel, non-chrome, non-sodium nitrite, non-nitrate, non-fluorine ions, non-three strong acids and easy degradation.

Description

technical field [0001] The invention relates to a chemical reaction cross-linking film forming of metals, in particular to a chromium-free passivator for iron and steel, zinc plates, aluminum and aluminum alloy parts, and zinc and zinc alloys. Background technique [0002] The film-forming process of paint, or the film-forming mechanism, is nothing more than two types: one is that the solvent evaporates and the paint dries to form a film. It does not undergo a chemical reaction, it is a physical phenomenon. Examples include nitro lacquer and vinyl lacquer. The other is to form a film through chemical reaction cross-linking. [0003] To prevent all metals from corrosion and maximize their service life is a way to utilize the limited resources on the earth. This is a common mission and common pursuit of all human beings. [0004] Endowing metal with the best performance to meet the high requirements of people's use and decoration to the greatest extent is a major topic and ...
