Metal anti-rust phosphating solution

Abstract

The invention provides a metal anti-rust phosphating solution, comprising the following raw materials by concentration: 2 g / L of octylphenol polyoxyethylene ether, 2 g / L of sodium polyoxyethylenelauryl ether sulfate, 2 g / L of diethyl thiourea, 10 g / L of phosphoric acid, 5 g / L of citric acid, 15 g / L of nickel sulfate (NiSO4.6H2O), 10 g / L of ferric sulfate, 10 g / L of zinc dihydrogen phosphate, 5 g / L of ferrocene, 5.0 g / L of sodium perborate, 2 g / L of hydroxyethyl cellulose, 5 g / L of gelatin, 40 g / L of aluminium hydroxide and 5 g / L of graphite. Harmful substances such as nitrate, nitrite, chromate and the like are not adopted, so that the metal anti-rust phosphating solution is environment-friendly. Meanwhile, an anti-rust object of the metal surface can be achieved; and a phosphating film formed by the phosphating solution has good corrosion resistance, thereby completely reaching relevant standards.

Description

technical field

[0001] The invention relates to a metal antirust phosphating solution, which belongs to the technical field of metal surface treatment agents. Background technique

[0002] Metal anti-rust phosphating solution is a phosphating treatment agent for anti-rust purpose. After smearing and drying on the metal surface, a phosphating film can be formed to prevent the metal from rusting. At the same time, the adhesion of the metal coating film can be improved after phosphating treatment . However, the phosphating treatment agents currently used are generally highly corrosive, and it is difficult to get rid of the harm caused by chemical rust removal during use and storage, such as the production of toxic and pungent odors. Along with the raising of people's environmental protection requirement, invent a kind of non-polluting, non-hazardous metal antirust agent and become an urgent problem to be solved.

Examples

Embodiment 1

[0027] Take hydroxyethyl cellulose and gelatin, add warm water at 50°C to dissolve completely, and set aside; take octylphenol polyoxyethylene ether, sodium lauryl polyoxyethylene ether sulfate and 1.3-diethylthiourea, add 50°C Dissolve in warm water, then add phosphoric acid and citric acid, after dissolving, add nickel sulfate, ferric sulfate, zinc dihydrogen phosphate, ferrocene, sodium perborate, stir for 1 hour, set aside; take aluminum hydroxide and graphite, add water to dissolve Finally, set aside; Combine the above solutions, add an appropriate amount of water, and stir evenly to make the raw material content meet the requirements of octylphenol polyoxyethylene ether 2g / L; sodium lauryl polyoxyethylene ether sulfate 2g / L; 1.3-diethyl Thiourea 2g / L; phosphoric acid 10g / L; citric acid 5g / L; nickel sulfate (NiSO 4 ·6H 2 O) 15 g / L; iron sulfate 10 g / L; zinc dihydrogen phosphate 10 g / L; ferrocene 5 g / L; sodium perborate 5.0 g / L; hydroxyethyl cellulose 2 g / L; gelatin 5 g / ...
