Problems solved by technology

For example, Chinese Patent Announcement No.: CN87101353A, CN152705A, CN1089310A and other patent announcements are all multi-functional rust-removing and anti-rust liquids with better performance, but there are still complex raw materials in ancestral graves. It is necessary to improve the shortcomings such as poor comprehensive performance

Abstract

The invention relates to a multifunctional antirust and derusting solution for metallic surface chemical pre-treatment, in particular to an antirust solution for highly efficient deoiling, derusting,phosphatization and passivation of steel at the normal temperature. The antirust solution comprises the following components(on a basis of the preparation of 250kg of finished products, the rest may be deduced by analogy): 7.35kg of zinc oxide, 105kg of phosphoric acid, 4.7L of nitric acid, 2.0kg of sodium chlorate, 0.15kg of manganese dioxide, 1.155kg of citric acid, and 130kg of water. The production process of the invention has no special requirement, and all components are just added to water serving a solvent in the proportioning in sequence and evenly stirred so as to obtain the finishedproduct. The antirust solution has the advantages of simple compositions, and easy buying and low price of raw materials; and tests prove that the use performance of the antirust solution is good, and the technology is advanced.

Description

1. Technical field: [0001] The invention relates to a multi-functional anti-rust and rust-removing liquid for chemical pretreatment of metal surfaces, in particular to a high-efficiency degreasing, rust-removing, phosphating, and passivation anti-rust liquid for iron and steel at room temperature. 2. Technical background: [0002] Novelty search proves: iron and steel rust removal and anti-rust technology and its product technology can be roughly divided into: rust removal and cleaning liquid, phosphating passivation anti-rust liquid, multi-functional rust and anti-rust liquid, ultra-low temperature multi-functional rust and anti-rust Liquid, paste rust remover and antirust agent, solid antirust agent and so on. The chemical raw materials they use can be divided into 10 categories after analysis and synthesis: main rust removal components of inorganic acids, main rust removal components of organic acids, oxidation catalytic rust removal accelerators, main film-forming rust i...
