Synthesizing type soft film anti-rust oil and preparation method

Abstract

The invention relates to the field of preservation and anti-corrosion of ferrous metal and copper alloy, in particular to synthesizing type soft film anti-rust oil and a preparation method. The synthesizing type soft film anti-rust oil contains the following raw materials in percent by weight: 72-75% of kerosene, 8-10% of mechanical oil No. 32, 5-6% of zinc naphthenate, 3-4% of barium dinonyl napthalene sulphonate, 1-2% of dodecenyl succinic acid, 3-4% of sodium alkylsulfonate, 1.5-2% of dibutyl phthalate, 0.2% of benzotriazole and 0.2% of 2, 6-di-tert-butyl-p-cresol. The anti-rust oil provided by the invention has an extremely obvious effect in inventory antirust and has an extremely good anti-rust effect on cast iron and copper, the anticorrosion preservation time of workpieces reaches more than two years, more importantly, the anti-rust oil is difficult to change color or oxidize in the sealed preservation process, and the sealed preservation is simple and convenient, namely the anti-rust oil preserved in a sealing way is wiped off by cotton yarns stained with a little kerosene or gasoline, so that the appearance of the workpieces is not influenced and excellent comprehensive performance is achieved; and the anti-rust oil has favorable universality.

Description

technical field [0001] The invention relates to the field of sealing and anticorrosion of ferrous metals and copper alloys, in particular to a comprehensive soft film antirust oil and a preparation method thereof. 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 ...

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
