Abstract

The present invention addresses the problem of providing a lubrication treatment method for a metal wire material that is not a combination of acid cleaning/alkaline degreasing and a phosphate/soap treatment, which has a heavy burden on the environment, but instead uses a shotblast and coating-type treatment agent to greatly decrease environmental burden, and adopts a batch scheme to have practical production efficiency, with a lubricating coating being uniformly formed on the metal wire material. The problem is solved by this lubrication treatment method for a metal wire material, which is a method for performing a batch-type lubrication treatment on a coil-shaped metal wire material, the method including: a descale step for performing a shotblast treatment on the coil-shaped metal wire material; and a lubricating coating forming step for coating a lubricating agent on the metal wire material after the descale step, wherein, in the descale step, the coil-shaped metal wire material satisfies L/(d×N)≥1.1, where L is the coil width, d is the wire diameter of the metal wire material, and N is the number of coil windings, and the lubricating agent contains one or more coating base components (A) selected from the group consisting of an inorganic salt and an organic acid salt, and a lubricating component (B).

Abstract

The present invention relates to a method for producing coated can lids from an aluminum strip and is based on the knowledge that flexible, easily deformable coatings having a high wear resistance can be produced by using water-based coats containing a copolymer or a copolymer mixture of at least one aliphatic and acyclic alkene having at least one α,β-unsaturated carboxylic acid in water-dispersed form and a curing system. In a preferred embodiment of the method, the need for applying a primer coating can be entirely avoided when water-soluble compounds of the elements Zr and/or Ti are used as a curing system in the coating.

Abstract

The present invention relates to the use of an aqueous composition for pretreating can body stock, in the course of which an inorganic-organic conversion layer is formed, which, as such, effects outstanding sliding behaviour of the shaped can body stock and in addition offers an outstanding holding primer for subsequent coating. The invention comprises in this case a process in which the can body stock which is deep drawn to form the half-open can cylinder, before further shaping processes, is contacted with an acidic aqueous composition which contains water-soluble inorganic compounds of the elements Zr, Ti, Si, Hf or Ce, water-soluble polymers having carboxyl groups or hydroxyl groups and also a dispersed wax. Both the outer and the inner surfaces of metallic can cylinders can be pretreated in the process according to the invention. In addition, the invention relates to an acidic aqueous composition that is particularly suitable in the pretreatment process, which aqueous composition contains water-soluble polymers selected from condensation products of glycoluril and aldehydes. In addition, a production process for can cylinders comprising the pretreatment according to the invention is described.

Abstract

The invention relates to the use of an acidic aqueous composition for pretreating cans, wherein an inorganic-organic conversion layer is formed in the course of the pretreatment, said conversion layer, as such, offering an excellent adhesive base for the wax which improves the sliding behavior of the formed can sheet metal and for the subsequent coating. The invention contains a wet-chemical pretreatment method in which a can cylinder is first brought into contact with an acidic aqueous composition that contains water-soluble inorganic compounds of the elements Zr, Ti, Si, Hf or Ce and water-soluble polymers comprising carboxyl groups or hydroxyl groups and subsequently with an aqueous dispersion of a wax. In this manner, the sliding and shaping properties required for the other method steps of the can production process are imparted to the can cylinders and an excellent adhesive base for a coating is additionally provided. The invention further relates to an acidic aqueous composition which is particularly suitable for the pretreatment method and which contains water-soluble polymers selected from the condensation products of glycoluril and aldehydes. The invention further relates to a method for producing can cylinders, said method including the pretreatment according to the invention.
