Abstract

The invention discloses a metal surface high-efficiency deoiling / derusting agent which is prepared from the following raw materials: 18-20 parts of phosphoric acid, 8-12 parts of hydrochloric acid, 5-8 parts of acetic acid, 3-5 parts of boric acid, 2-3 parts of ferric hydroxide, 2-4 parts of ammonium oxalate, 3-5 parts of diethyl ethanedioate, 4-6 parts of sodium acetate, 3-5 parts of potassium iodide, 2-3 parts of phenol, 4-5 parts of sodium lactate, 1-3 parts of citric acid, 3-6 parts of resorcinol, 4-5 parts of p-hydroxyanisole, 3-4 parts of sodium carbonate, 5-6 parts of ethylenediamine tetra(methylenephosphonic acid), 1-2 parts of ammonium bicarbonate and 25-30 parts of pure water. The metal surface high-efficiency deoiling / derusting agent can remove oil and rust at high speed at normal temperature, can prevent the metal base from being corroded, can inhibit acid mist, and has the excellent synergetic effect.

Description

Technical field [0001] The invention relates to the technical field of an oil and rust remover for metal surface treatment, in particular to an efficient oil and rust remover for metal surfaces. Background technique [0002] In the past, the degreasing and derusting of metal surfaces were carried out in sections: first degreasing in lye, and then derusting in acid. Recently, oil removal and rust removal can be carried out in one step or at the same time. The key point is the combination and use performance of each formula raw material, and the oil removal and rust removal technology has been widely used in related industries. However, these existing technologies still have such shortcomings in the selection and preparation of raw material formulations, especially in terms of anti-corrosion, operation, etc., there are more or less defects and shortcomings. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortcomings of the prior art ...
