Rust-proof paste for treating surface corrosion of metal material

Abstract

The invention discloses rust-proof paste for treating surface corrosion of a metal material. The rust-proof paste consists of the following raw materials in parts: 10-15 parts of sodium hydroxide, 20-25 parts of sodium carbonate, 50-80 parts of nitric acid, 5-10 parts of charcoal powder, 10-12 parts of corncob powder, 12-15 parts of bauxite powder, 5-10 parts of fireproofing mud glue, 12-15 parts of ethylenediamine, 3-5 parts of eriochrome black t, 5-8 parts of thiourea, 2-5 parts of formaldehyde, and 50-80 parts of de-ionized water. The rust-proof paste for treating the surface corrosion of the metal material is paste at the normal temperature, and can be utilized to coat a metal rust place, then the paste is scraped off after several minutes, and the rust-proof purpose can be achieved after the water cleaning. The rust-proof paste is low in production cost, can help to improve the working environment and shorten the process steps, and is easy to operate and master.

Description

technical field [0001] The invention relates to the technical field of rust removing paste, in particular to an antirust paste for treating surface corrosion of metal materials. Background technique [0002] At present, before the ferrous metal is coated, the surface should be pretreated to remove the oil stains, impurities and rust layers on the surface, and the general treatment method is to use a liquid rust remover. And most of them adopt a single treatment method, that is, degreasing, derusting, phosphating, and passivation treatment are carried out separately and in sequence, and are carried out step by step in several tanks (that is, setting up degreasing, derusting pools, passivation pools, Clean water tank), etc., so it occupies a large area, consumes a lot of water, causes serious pollution, complex process operation, high labor intensity, and endangers the health of operators. Contents of the invention [0003] The purpose of the present invention is in order ...
