Gaseous-phase antirust material with long-acting antirust effect and preparation method thereof

Abstract

The invention provides a gaseous antirust material with a long-acting antirust effect. The gaseous antirust material comprises the following materials in parts by weight: 2.2-6.5 parts of ammonium benzoate, 15.5-25.5 parts of sodium nitrite, 72.5-81.5 parts of distilled water, 0.2-0.6 part of an emulgator, 5.5-8.5 parts of an enhancer and 3.5-5.5 parts of antirust microcapsules. The invention also provides a preparation method for the gaseous-phase antirust material with the long-acting antirust effect. The gaseous antirust material prepared in the manner of adding a gaseous slow-release material into the microcapsule according to the invention is capable of slowly releasing the stored gaseous slow-release material and has controllability. According to the invention, the enhancer is added in the process of preparing the gaseous antirust material, so that the adhesion of the antirust material on a thin oil film is greatly promoted, the antirust material is difficult to dry, crack, becomes crispy and falls off, the influence that the antirust effect become poor due to outdoor exposure and cold temperature can be reduced and the antirust effect is promoted.

Description

technical field [0001] The invention relates to a gas phase antirust material and a preparation method thereof, in particular to a long-term antirust gas phase antirust material and a preparation method thereof. Background technique [0002] The bead wire is easily corroded by the external environment or medium in the process of manufacturing, storage and use. After the surface is corroded and rusted, the performance and commodity value of the equipment will be greatly damaged, and even its use will be greatly affected. Life expectancy, or cause major accidents, cause great losses to the national economy and national defense construction. Therefore, the protection of the steel wire surface is of great significance to the development level of the machinery manufacturing industry, to safe production, and to the utilization efficiency of natural resources. [0003] Soft film anti-rust is one of the important ways to protect the surface of steel wire. Compared with other types ...

AI Technical Summary

Problems solved by technology

However, due to the fact that the existing soft film antirust oil products tend to focus on certain aspects of performance, the oil film is thin, easy to flow or dry and brittle, and the comprehensive performance is not good, and the antirust effect is poor when the use environment is relatively complicated or harsh.

Chinese patent CN102031189A discloses a soft film antirust oil, which mainly consists of kerosene, machine oil, zinc naphthenate, barium dinonylnaphthalenesulfonate and other antirust agents. The oil film is thin, the strength is low, and the dropping point is low. Easy to lose under the action of light;

[0004] Chinese patent CN201310333257.4 discloses an anti-rust soft film composition and its preparation method. The gas phase corrosion inhibitor in the anti-rust soft film is self-volatile, and the anti-rust film after drying and forming a film can automatically volatilize the anti-rust gas , this kind of anti-rust gas can effectively prevent the corrosion of the steel wire at the damaged part of the anti-rust film (before self-repair) or the missing coating part. It is especially suitable for the inner surface of the inner cavity, pipe, groove, etc. The anti-rust time of the seed film is not long enough; at the same time, the mechanism is that when the anti-rust film is damaged by extrusion, scratching, collision, washing, etc. during use, the wall material of the microcapsule anti-rust agent will also be damaged. At this time, the anti-rust agent in the microcapsules can automatically flow out and form a film, thereby endowing the anti-rust soft film with a self-repairing function, which results in the addition of no damage or less damage, and the anti-rust effect will be compromised
