Abstract

The invention relates to a dehydrated antirust oil composition and application thereof. The problem that in the prior art, sealing antirust performance and dehydrate performance can not be well achieved at the same time is mainly solved. The dehydrate antirust oil composition is prepared from, by weight, 75-95 parts of base oil, 5-15 parts of oil-soluble sulfonic acid calcium salt, 0.5-7 parts of additives and 0.1-3 parts of dehydrating agent. According to the technical scheme, the problems are well solved, and the dehydrated antirust oil composition can be used for industrial production.

Description

technical field [0001] The present invention relates to a dehydrated rust-preventive oil composition and its use. Background technique [0002] In recent years, with the rapid development of my country's auto parts processing industry, after the metal products used for various auto parts are processed and cleaned with aqueous media such as cutting fluids and cleaning agents, a small amount of water or water remains on the surface of the auto parts workpiece. If the medium is coated with anti-rust oil without dehydration function, the water stains on the surface cannot be effectively removed, and it is easy to cause the rust of the workpiece. As a dehydration and antirust oil used in water-soluble cutting fluid processing and water-based cleaning agent post-treatment processes, it has been widely used in the production process of the auto parts industry. [0003] In the prior art, there are many types of dehydration and antirust oils. Document CN1353173A discloses a new type...
