Definitions

• the invention relates to a cold washable lubricant composition and a dry lubricant composition and their use for application on a metal strip as corrosion protection, washing and / or forming lubricant.
• Lubricants in metalworking perform various tasks.
• rolling oils or rolling emulsions are used, which are applied to the metal strip in order to influence the friction conditions between roll and strip for an optimum rolling result.
• Rolled oils differ in viscosity and in the presence and concentration of additives to improve lubricity, polar and non-polar additives, depending on the metal and tool.
• Typical additives are high pressure (EP) additives and antiwear additives such as sulfur or phosphorus carriers as well as corrosion inhibitors, e.g. Sulfonates.
• a corrosion inhibitor is applied to the surface of the metal belts to prevent corrosion during storage and transportation. As a result, the adherence of the stacked or rolled up to the coil (tape rolls) metal strips is avoided.
• this corrosion inhibitor is removed by means of a wash oil or an alkaline cleaner and applied, for example, a drawing or stamping oil, which reduces the friction during the forming of the metal strip and thus facilitates the processing and ensures improved forming results or reduces the number of defective forming products.
• the washing, drawing, stamping or other forming oils used in the metalworking plant may be, for example, aqueous emulsions or aqueous synthetic solutions or medium to high viscosity oil formulations.
• aqueous alkaline cleaners are usually used, which preferably consist of a two-component system in automotive body shops: a salt framework (builder) component and a surfactant component. Cleaning is usually carried out by spraying / immersion at typical application temperatures of 50 to 60 ° C.
• a so-called prelube can be applied in the steel or aluminum plant after the rolling to finish the rolling stock.
• Prelubes are compositions that combine the properties of a corrosion protection oil with the lubricity of a drawing oil. Like the anticorrosion agents, prelubes prevent corrosion and sticking during transport and storage of the metal strip coils, but also serve as a drawing lubricant in the press shop. At Prelubes, too, it is very important, especially in the automotive sector, to have excellent compatibility with every single process, from the cold-rolled strip to the body shell. If the prelube in the production chain is compatible with every step of the process (in particular welding, gluing, etc.) up to and including painting, there is a significant reduction in the number and quantity of lubricants used in the press shop (wash oils, drawing, stamping or other forming oils) and allows the work to be performed.
