Wet leveling agent for bell-type annealing secondary cold-rolled tin-plated extremely thin sheet

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 ...

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
