Multi-effect and quick-drying punching forming oil and preparation method thereof

Abstract

The invention discloses multi-effect and quick-drying punching forming oil. The forming oil comprises the following components by weight percent: 1-10% of conductive corrosion inhibitor, 1-15% of total-synthesis volatile interface lubricant, and the balance of solvent oil added to 100%, wherein the total-synthesis volatile interface lubricant material comprises oleic acid, dodecanoic acid, and bis-propane; the weight percent of the oleic acid to the dodecanoic acid to the bis-propane is 100 to 10 to 20. The multi-effect and quick-drying punching forming oil prepared by the method has the characteristics of being fast to volatilize, free of cleaning, and free of color aberration at surface of a work-piece; assembly line work can be achieved; the work-piece can directly enter the next procedure; the anti-rust and anti-corrosion ingredients can provide anti-rust protection on a black metal work-piece for over 15 days, and provide anti-corrosion protection on non-ferrous metal for over 30 days. The anti-rust and anti-corrosion ingredients have conductive characteristics, do not need to be removed in subsequent procedures and can be directly welded; a salt spray test of a 5# carbon steel standard element is over 4 hours; the corrosion test of a copper sheet is 1A level; the PB value is greater than 128 N. The multi-effect and quick-drying punching forming oil can be applied to punching and forming of black metal sheets which are less than 1mm, and non-ferrous metal sheets which are less than 2mm.

Description

technical field [0001] The invention relates to a lubricant used in the punching and shearing forming process of metal sheets, in particular to a multi-effect quick-drying punching and shearing forming oil and a preparation method thereof. Background technique [0002] Stamping punching shearing is a processing technology commonly used in sheet metal processing. In the process of sheet metal punching shearing forming, the punching shear oil used has two types: volatile and non-volatile. The volatile punching shear oil can volatilize quickly, so it is Belongs to the disposable type. Although the traditional punching and shearing oil can quickly volatilize and achieve the purpose of no-cleaning, but because its lubricating performance and anti-rust performance cannot meet the requirements, it is likely to cause excessive wear of punches and molds. If the lubricating oil components If it is too high, although it satisfies the lubricating performance and antirust performance, i...

Problems solved by technology

Although the traditional punching and shearing oil can quickly volatilize and achieve the purpose of no-cleaning, but because its lubricating performance and anti-rust performance cannot meet the requirements, it is likely to cause excessive wear of punches and molds. If the lubricating oil components If it is too high, although it satisfies the lubricating performance and antirust performance, it is easy to absorb on the surface of the plate to form grease, which is not conducive to cleaning. It needs to be cleaned with a special cleaning agent, which increases the cost of use, and the cleaning effect is directly related to It affects the use of the workpiece in the next process, which in turn increases the operating procedures and steps, affecting the processing efficiency

After long-term storage, the traditional punching and shearing forming oil is likely to separate out, which will affect the quality and use effect of punching and shearing forming oil

[0003] Therefore, a new type of punching and shearing oil is needed, which can solve the technical problems of lubrication, rust prevention, corrosion prevention and no-cleaning between processes
