preparation example Construction

[0041] The preparation method of above-mentioned acid environment-friendly cleaning agent is as follows:

[0042] (1) Group A raw materials: add an appropriate amount of water to a stainless steel container, add phosphoric acid in proportion, and stir magnetically for 5 minutes; Stir for 5 minutes; continue to add an appropriate amount of phytic acid to the container, stir magnetically for 5 minutes, continue to add appropriate amount of other organic acids to the container, and stir magnetically for 5-10 minutes.

[0043] (2) Group B raw materials: Add an appropriate amount of water into a stainless steel container, add an oxidizing agent into the container, and stir magnetically for 5-10 minutes until the oxidizing agent is completely dissolved.

[0044] (3) Group C raw materials: Add an appropriate amount of water into a glass beaker, heat to 80-90°C, add an appropriate amount of polymer dispersant, and stir magnetically for 50-60 minutes to fully dissolve the polymer dispe...

Embodiment 1

[0049] Calculated on the basis of 100 parts of cleaning agent, choose 20 parts of phosphoric acid, 5 parts of hydroxyethylidene diphosphonic acid HEDP, 1 part of phytic acid, 5 parts of citric acid, 1 part of tartaric acid, 2 parts of sodium nitrate as the oxidant, and 1 part of phytic acid. The dispersant is 2 parts of polyethylene glycol 2000, 0.5 part of organic corrosion inhibitor thiourea, 2 parts of organic penetrant JFC, and the balance of water.

Abstract

The invention relates to an acidic environment-friendly cleaning agent and a preparation method thereof. The acidic environment-friendly cleaning agent comprises, counted by 100 parts, 10-40 parts ofphosphoric acid, 2-20 parts of 1-hydroxyethylidene 1,1-diphosphonic acid, 0.1-10 parts of phytic acid, 0.5-10 parts of other organic acids, 1-10 parts of an oxidizing agent, 0.2-5 parts of a polymericdispersing agent, 0.1-2 parts of an organic corrosion inhibiting agent, 0.5-2 parts of an organic penetrating agent and the balance of water. The other organic acids can be citric acid, oxalic acid,tartaric acid, formic acid, acetic acid and the like. The oxidizing agent can be sodium nitrate, zinc nitrate, calcium nitrate and the like. The polymeric dispersing agent can be polyvinyl alcohol 1688, polyethylene glycol 2000, polymaleic anhydride and the like. The organic corrosion inhibiting agent can be thiourea, imidazoline oleate, 1H-benzotriazole and the like. The organic penetrating agentcan be JFC, alkylphenol ethoxylates, nonylphenol ethoxylates and the like. The cleaning agent has the function of removing scale and removing rust, no waste gas is generated in the cleaning process,and the technical effects of environment friendliness and increasing of the cleaning quantity can be achieved.

Description

technical field [0001] The invention belongs to the field of cleaning agents, and in particular relates to an acidic environment-friendly cleaning agent and a preparation method thereof. Background technique [0002] During the high-temperature rolling and subsequent cooling process of the steel wire, a layer of oxide skin will be formed on the surface. This dense oxide layer is not easy to clean. If it is not cleaned, the residual oxide skin will be easily damaged in the subsequent drawing or cold heading process. It will cause defects on the surface of the wire rod, and will accelerate the wear of the mold used in the manufacturing process. During the storage and transportation of these steel wire rods, the surface with oxide skin will be in contact with the air again, causing rust on the steel surface. If the rust is not cleaned, it will also affect subsequent processing. Therefore, before subsequent processing, the oxidation of the steel wire rod surface Both skin and r...
