Abstract
The invention provides degreasing-free punching and cleaning oil for an automobile steel plate, and a preparation method thereof. The punching and cleaning oil comprises the following components: refined mineral oil, an extreme pressure antiwear additive, an antirust agent, a film-forming agent, an emulsifier, a dispersant, a surfactant and an antioxidant. The punching and cleaning oil integrates cleaning, punching and rust protection and can remove mechanical impurities form the surface of the steel plate when the steel plate is subjected to on-line cleaning and punching formation, and the antirust life of the cleaned steel plate can reach 3 months; the surface of the formed part is clean, does not have punching residues and does not need to be cleaned; a high lubricating property is achieved, the steel plate can be directly subjected to punching formation after being cleaned and does not need to be coated with oil special for punching formation; the residual oil on the surface of the cleaned and punched material piece does not need a degreasing procedure and can be removed through water washing, so the steel plate forming process is simplified, the use amount of punching oil, cleaning oil and a degreasing agent is reduced, energy conservation and environmental friendliness are achieved, and economic benefit is improved.
Description
technical field [0001] The invention relates to the technical field of a degreasing-free stamping cleaning oil for automobile steel plates, in particular to a degreasing-free stamping cleaning oil for automobile steel plates with excellent cleaning properties, rust resistance and lubricating properties and a preparation method thereof. Background technique [0002] Stamping cleaning oil is mainly used in stamping and cleaning of automobile steel plates. The performance requirements of stamping cleaning oil are: it can be removed by washing, excellent cleaning performance, rust resistance, lubricity and matching performance of subsequent coating. At present, most stamping cleaning oils need to be degreased after use, and cannot take into account the matching performance of cleaning performance and rust resistance, rust resistance and subsequent coating at the same time. Automobile steel sheets are not clean or clean after cleaning, resulting in insufficient lubrication and s...
