Rust preventive oil and preparation method thereof

Abstract

The invention relates to the field of ferrous metal and copper alloy sealing storage and corrosion prevention, and particularly relates to rust preventive oil and a preparation method thereof. The rust preventive oil consists of the following raw materials in parts by weight: 62-65 parts of kerosene, 5-6 parts of zinc naphthenate, 2-3 parts of triethoxyvinylsilane, 2-3 parts of dodecenylsuccinic acid, 3-5 parts of diethylene glycol monoethyl ether, 0.2 part of Vaseline and 0.2 part of 2,6 butylated hydroxytoluene. The rust preventive oil plays an outstanding rust preventing role in storage and has an excellent rust preventing effect on cast iron, copper and the like; a workpiece can be stored for over two years in sealing by corrosion prevention; more importantly, the rust preventive oil neither discolors easily nor oxidizes easily; in addition, sealing removal is simple and convenient, the sealed rust preventive oil can be wiped away just by means of wetting spun cotton with a little kerosene or gasoline, and the appearance of the workpiece is not affected; the rust preventive oil is excellent in comprehensive properties and strong in universality.

Description

technical field [0001] The invention relates to the field of anti-corrosion, in particular to an anti-rust oil and a preparation method. Background technique [0002] In the metal processing industry, since the workpiece has to go through multiple processes from the blank to the finished product, it must be stored in the warehouse because it is reserved or cannot be processed in the next process in a short period of time. During the inventory process, the metal will be lost Because the surrounding environment is more or less corroded, the corrosion will affect its own characteristics and hinder its subsequent processing or use. The loss caused by metal corrosion is huge every year, and the significance of protection is particularly important. [0003] For long-term anti-rust in stock, the common practice now is to coat the surface of the workpiece with anti-rust oil before stocking. The soft-film anti-rust oils currently on the market mainly contain one or two kinds of cor...

Problems solved by technology

[0003] For long-term anti-rust in stock, the common practice now is to coat the surface of the workpiece with anti-rust oil before stocking. The soft film anti-rust oil sold in the market is mainly It is composed of one or two kinds of corrosion inhibitors, film-forming agents and additives. The composition is relatively simple. It has excellent performance in one or a few specific aspects, but its overall performance is not good, such as in corrosion resistance, resistance Salt spray corrosion performance, water and sweat replacement performance, oil film drying time after oiling, coating film thickness, and oil film removal cannot be fully considered

[0004]Because of China's vast territory and different climate types, the corrosion environment of metals is varied. Even the corrosion environment in the same area also has different changes. When metals are required When storing anti-rust, it is necessary to carefully select the anti-rust oil used according to different corrosion environments and different corrosion seasons, which is time-consuming and laborious, and the versatility of the anti-rust oil is very poor
