Problems solved by technology

[0009] However, when using the resin-coated tin-plated steel sheet of Patent Document 1, when the double processing process of elastic force and shrinkage after forming the tank body is used, resin peeling on the upper part of the tank body or adhesive film during the processing of the tank body may occur during the forming process. The problem of insufficient processing adhesion

Embodiment

[0094] Hereinafter, the present invention will be specifically described through Examples 1-12 and Comparative Examples 1-3.

[0095] 〔Production of tin-plated steel sheet〕

[0096]Use the low-carbon cold-rolled steel sheet shown in the "plate thickness" column of Table 1, after electrolytic degreasing in alkaline aqueous solution-washing and sulfuric acid pickling-washing, use the acidic tin plating ferrostan method to make a plated steel plate under the conditions shown in Table 1. Melt treatment is performed after the tin layer.

[0097] Next, smear the silane coupling agent on the top of the tin plating layer and let it dry to prepare the silane coupling agent smear layer with the Si adhesion amount shown in the examples and comparative examples in Table 1.

[0098] 〔Production of resin-coated metal sheets〕

[0099] As shown in Examples 1 to 12 and Comparative Examples 1 to 3, according to the conditions listed in the table, a transparent non-stretchable adhesive film of...

Abstract

Provided is a method for manufacturing a resin-coated metal sheet having excellent film working adhesiveness even at the time of rigorous forming working. The method for manufacturing a resin-coated metal sheet includes the steps of: forming a tin-plating layer on at least one surface of a metal sheet; applying a silane coupling agent to the tin-plating layer by coating; forming a resin layer on the silane coupling agent coating layer; and melting a resin surface of the resin layer on a side where the resin surface is in contact with the silane coupling agent by heating the metal sheet. The method also includes a step of heating at least an interface region between the tin-plating layer and the silane coupling agent coating layer, the silane coupling agent coating layer, and an interface region between the silane coupling agent coating layer and the resin layer at a temperature which falls within a range from a temperature 10°C below a melting point of a resin to a temperature 100°C above the melting point of the resin.

Description

technical field [0001] The present invention relates to a method of manufacturing a resin-coated metal sheet having excellent process adhesion. Background technique [0002] In recent years, the use of strict processing processes such as forming of resin-coated steel sheets, elastic processing after forming, shrinking after forming, and double processing of elastic and shrinking after forming to manufacture cans or The can body and the bottom of the tank are integrally formed with an iron can with a screw-on top cover. [0003] In order to avoid problems such as peeling or cracking of the resin coated on these cans during the strict molding process and after the molding process, the adhesive performance of the resin used for the steel plate is very important. [0004] Therefore, these tank materials are made of tin-plated steel plates with a layer of butyrate coating on the surface with excellent processing adhesion, such as steel plates that have been treated with butyrate...
