Problems solved by technology

[0004] At present, the domestic water-based anti-rust liquid has the following problems: (1) The anti-rust effect in the typical stock environment is not ideal
Although there are many normal-temperature water-based anti-rust liquids in China, most steel mills generally heat the water-based anti-rust liquid to 50-70°C for immersion in order to improve the anti-rust effect when dipping ferrous metals. Coating, time-consuming and energy-consuming; (4) Higher cost
The anti-rust effect of the existing water-based anti-rust liquid is not ideal, and the manufacturer will recommend increasing the concentration to achieve the desired purpose, which increases the cost of use

Abstract

The invention discloses an environment-friendly water-based antirust liquid formula. The formula includes, by weight, 10-20 parts of phytic acid, 10-15 parts of konjac glucomannan, 3-12 parts of a-D-glucose pentaacetate, 0.5-5.5 parts of carboxymethyl cellulose, 2-5 parts of sodium alginate, 5-15 parts of sebacic acid, 1-5 parts of triethanolamine, 30-80 parts of deionized water and 1-2 parts of antioxidant. An antirust liquid preparing method is simple, the antirust effect is good, good rust prevention can be achieved at low concentration, no toxin exists, the antirust liquid is harmless to the human body and the environment, and the environment-friendly water-based antirust liquid formula can be applied to rust prevention in high-temperature and high-humidity environments for ethyl HT300 cast iron of hot-rolled steel plates and cold-rolled steel plates.

Description

Technical field: [0001] The invention relates to the technical field of metal surface treatment, in particular to an environment-friendly water-based antirust liquid formula. Background technique: [0002] In 2013, China's crude steel output reached 779 million tons, accounting for 48.5% of the global total. However, about 10 million tons of steel are scrapped due to corrosion every year in my country. Therefore, it is extremely important to develop environmentally friendly and efficient steel antirust products. Among many anti-rust products, water-based anti-rust liquid has attracted wide attention due to its non-toxic and environmentally friendly advantages of using solvent water instead of solvent oil. [0003] Water-based antirust agent is made of water as a solvent, adding various water-soluble corrosion inhibitors, chelating agents, film-forming agents, surfactants, stabilizers, defoamers, bactericides, etc., which can inhibit the chemical corrosion of metal products. ...
