Abstract

The invention relates to a water-based antirust agent for metals. The water-based antirust agent comprises, by weight, 50 to 70 parts of inositol hexaphosphate, 10 to 20 parts of sodium citrate, 5 to 10 parts of sodium hydrosulphite, 15 to 20 parts of sodium dodecyl benzene sulfonate, 10 to 15 parts of zinc sulfate, 2 to 4 parts of glycerin and 5 to 10 parts of hydrochloric acid, with the balance being water. The invention has the following beneficial effects: the water-based antirust agent is applicable to long-term antirust treatment of steel and a variety of non-ferrous metals, and has substantial derusting effect and low cost.

Description

technical field [0001] The invention belongs to the field of industrial antirust agents, in particular to a water-based metal antirust agent. Background technique [0002] Existing anti-rust agents all contain nitrite, phosphate and other substances, which have pollution problems in emission, and the processing cost is relatively high. Although the anti-rust effect can be achieved in terms of rust removal, it cannot form an anti-rust agent on the metal surface. Rust protective film. Contents of the invention [0003] In view of the above disadvantages, the present invention provides a water-based metal antirust agent, which not only has a remarkable derusting effect, but also forms a layer of antirust protective film on the metal surface to achieve a long-term antirust effect. [0004] The technical solution adopted by the present invention to solve the technical problem is: a water-based metal antirust agent, which consists of the following components in parts by weight:...
