Abstract

The invention discloses an environment-friendly universal rust remover. The environment-friendly universal rust remover is mainly prepared by mixing and dissolving the following raw materials including, by weight percent, 1%-10% of EDTMPS, 1%-10% of edetate disodium, 5%-15% of sodium dihydrogen phosphate, 5%-15% of zinc dihydrogen phosphate, 0.1%-0.5% of an enzyme preparation, 0.1%-1% of a conversion film medium, 0.05%-0.2% of a chelating agent, 0.01%-0.05% of a complexing agent and the balance deionized water. The environment-friendly universal rust remover has the advantages of improving thebinding force of paint, enhancing the corrosion resistance, and achieving the antirust effects of being quick in rust removal, free of pollution, healthy and environment-friendly.

Description

technical field [0001] The invention relates to a metal surface derusting technology, more specifically, the invention relates to an environmentally friendly universal derusting agent with excellent characteristics of quick derusting and environmental protection. Background technique [0002] At present, with the continuous development of industry, more and more metal materials are used in industrial products, but corrosion problems are also coming. The rapid derusting method used in industrial processing usually uses steel pickling derusting agent In order to achieve the effect of rapid rust removal, but after the rust removal by pickling rust remover, the steel will rust again with the action of oxygen. If it is not used in time after rust removal, it needs to be rusted again. The production of the rust remover and antirust agent solves such troubles, and the rust remover and antirust agent can completely avoid secondary rusting after use. [0003] However, the rust remov...
