Description

A kind of oil water removal based anti-rusting agent and preparation method thereof

Technical field

The present invention relates to metal treatment field, be specifically related to a kind of oil water removal based anti-rusting agent and preparation method thereof.

Background technology

Metal works, in the process of process for processing and transport, is easy to get rusty, and once get rusty, and produces detrimentally affect by the outward appearance of finished product and performance, and the serious steel that even can cause of corrosion are scrapped.Iron and steel gets rusty and to bring about great losses to national economy, therefore needs to use rust-preventive agent to protect metal.The mode of action of rust-preventive agent prevents metal generation corrosion by forming thin film in metallic surface.Conventional rust-preventive agent major part is oiliness, and it uses a large amount of organic solvent in the process of production, use, and to environment, therefore the research of water-based antirust has great importance.

Traditional water-base metal antirusting agent great majority all contain nitrite, and it has the advantages such as inexpensive, respond well and easy to use, easy removal, but can change into carcinogens due to nitrite, and it uses and discharge and is subjected to strict restriction.At present, the research of novel environment friendly water-based antirust starts to be paid close attention to widely, becomes a kind of developing trend.
