Problems solved by technology

[0004] The production of bell annealed (BA) secondary cold-rolled tinplate is difficult and requires high quality control. However, due to its advantages such as good deep drawability, BA secondary cold-rolled tinplate still has a large number of user needs
The low quality of bell-type annealed secondary cold-rolled tin-plated products has always been a problem that plagues on-site production. In addition to the shape and thickness, the main problems of secondary cold-rolled tin-plated products are surface problems, mainly including color difference, longitudinal Defects such as stripes, watermarks, foreign matter pressure, vibration marks, emulsion stripes, "small bright spots" have seriously affected the use of users and hindered the process of market development

Embodiment 1

[0021] In the present embodiment, take triethanolamine 30%, dodecenyl succinic acid 10%, N-oleoyl sarcosine stearylamine 20%, polyacrylamide 15%, octylphenol polyoxyethylene ( 10) 15% ether, 5% ethylenediaminetetraacetic acid, and 5% sodium gluconate. After mixing these raw materials evenly, the wet leveler for secondary cold-rolled tin-plated extremely thin plates of the present invention is obtained. The wet leveling agent is diluted with water to 2% by weight and then leveled, has excellent cleaning performance and anti-rust performance, improves plate shape and surface quality, and meets the requirements of secondary cold rolling.

Embodiment 2

[0023] In the present embodiment, take triethanolamine 30%, dodecenyl succinic acid 5%, N-oleoyl sarcosine stearylamine 10%, polyacrylamide 10%, octylphenol polyoxyethylene ( 10) Ether 25%, ethylenediaminetetraacetic acid 10%, sodium gluconate 10%, after mixing these raw materials evenly, obtain the wet leveling agent for secondary cold-rolled tin-plated extremely thin plate of the present invention. The wet leveling agent is diluted with water to 2.5% by weight and then leveled, has excellent cleaning performance and anti-rust performance, improves plate shape and surface quality, and meets the requirements of secondary cold rolling.

Embodiment 3

[0025] In the present embodiment, take triethanolamine 20%, dodecenyl succinic acid 9%, N-oleoyl sarcosine stearylamine 18%, polyacrylamide 14%, octylphenol polyoxyethylene ( 10) 23% ether, 7% ethylenediaminetetraacetic acid, and 9% sodium gluconate. After mixing these raw materials evenly, the wet leveler for secondary cold-rolled tin-plated extremely thin plate of the present invention is obtained. The wet leveling agent is diluted with water to 3% by weight and then leveled, has excellent cleaning properties and anti-rust properties, improves plate shape and surface quality, and meets the requirements of secondary cold rolling.

Abstract

The invention discloses a wet leveling agent for bell-type annealing secondary cold-rolled tin-plated extremely thin plate. The wet leveling agent is composed of the following components by weight percentage: triethanolamine: 20-30%, dodecenyl Succinic acid: 5-10%, N-oleoyl sarcosine octadecylamine: 10-20%, polyacrylamide: 10-15%, octylphenol polyoxyethylene (10) ether: 15-25%, Ethylenediaminetetraacetic acid: 5-10%, sodium gluconate: 5-10%. The wet leveling agent of the present invention has the advantages of stable performance, good rust resistance and cleaning performance, no strong irritating smell, and no influence on the operating environment.

Description

technical field [0001] The invention relates to a wet leveling agent for bell-type annealing secondary cold-rolled tin-plated extremely thin plates (that is, plates below 0.20mm), and belongs to the protection technical field. Background technique [0002] Cold-rolled electroplated tinplate is mainly used in the packaging industry, usually with tin-iron alloy layer (FeSn2), pure tin layer, tin oxide layer and surface oil layer, with beautiful appearance, high strength, light weight, good formability resistance, and good resistance to organic substances, dilute acids, alkalis and salt corrosion. [0003] At first, the electroplated tinplate was produced only once by cold rolling, but the current development trend of the tinplate is to continuously improve the strength of the tinplate while reducing the quality. In order to adapt to this development trend, the secondary cold-rolled electroplated tinplate is becoming more important. In the packaging industry, the consumption ...
