Copper alloy antirust agent

Abstract

The invention discloses a copper alloy anti-rusting agent which comprises a rust remover, a passivator, a surfactant, a degreaser and pure water, wherein, the weight percentage of the rust remover is 10 percent to 20 percent, the passivator is 5 percent to 15 percent, the surfactant is 1 percent to 10 percent and the degreaser is 1 percent to 5 percent, and the rest is pure water. The copper alloy anti-rusting agent is a water-soluble cleaning agent, has good dust-removing effect to the surface of copper alloy, little corrosion, high-efficiency degreasing performance and anti-rust function after cleaning, keeps an antioxidant surface for a long time, meets the requirements of environment protection and has the advantages of reasonably-designed formula, simple preparation technology and lower cost.

Description

technical field [0001] The invention relates to a rust remover, in particular to a copper alloy rust preventer. Background technique [0002] Ferrous metals refer to iron, manganese, chromium and their alloys. Such as steel, pig iron, ferroalloy, cast iron, etc. Both steel and pig iron are alloys based on iron with carbon as the main additive element, collectively referred to as iron-carbon alloys. Ferrous metals are widely used in metallurgical iron and steel industry, machinery and equipment manufacturing, shipbuilding, national defense industry, petroleum machinery industry, aircraft, automobile, motorcycle manufacturing, textile, hardware, mold, instrument, medical equipment industry, chrome plating of various steel workpieces It can be seen in many industries such as galvanizing and deep processing. In order to further improve the quality of ferrous metal and ensure its good appearance in use, it is necessary to carry out rust and anticorrosion treatment on it. Howe...

Problems solved by technology

However, the appearance of ferrous metal workpieces processed by derusting often has pockmarks, that is, irregular surface defects; in addition, the surface is prone to scarring, because the material of the steel is uneven and there are many impurities. After derusting, the impurities are exposed on the outside, scarred

The workpiece after derusting is easy to scratch, and burrs will appear on the surface of the workpiece after derusting, and the contact between the workpiece and the workpiece will scratch the surface, and deep scratches will reduce the strength of the workpiece
