Gas-phase rust-preventing aerosol and preparation process thereof

Abstract

The invention discloses a gas-phase rust-preventing aerosol and a preparation process thereof. The formula of the gas-phase rust-preventing aerosol comprises the following components in parts by mass: 0.5-1.5 parts of caprylic acid tributylamine, 1-3 parts of benzotriazole tributylamine, 2.5-3.5 parts of oleic acid, 1-3 parts of laurinol, 0.2-0.8 part of amino silicon oil, 2.5-3.5 parts of methyl oleate, 0.2-0.8 part of sodium petroleum sulfonate, 0.2-0.8 part of barium petroleum sulfonate, 0.5-1.5 parts of capric acid tributylamine, 51.5-61.5 parts of 20# machine oil and 27-33 parts of liquefied petroleum gas. The process comprises the following steps: mixing and stirring the raw materials; filling the obtained liquid into a spray can; inserting a capillary valve; filling the liquefied petroleum gas; performing leak detection, and blowing-dry; and boxing, and warehousing. The invention has the characteristics of small aerosol particle diameter and high aerosol particle uniformity DR, and can effectively enhance the corrosion inhibition effect of a metal component.

Description

technical field [0001] The invention belongs to the technical field of metal rust prevention, and in particular relates to a gas-phase antirust aerosol and a preparation process thereof. Background technique [0002] With the development of economic globalization, most assembly manufacturers need to purchase components produced all over the world for assembly. During shipping, the harsh marine climate environment will cause metal parts to be slowly corroded during long-term shipping. The current commonly used method is to spray a layer of anti-rust oil on its outer surface to protect it from corrosion by the outside air. However, the effective mist particles sprayed by the existing gas-phase antirust agents are relatively large, generally a better diameter is 30-50um, and some even reach 80-100um, and its uniformity DR is greater than 0.65. The mist particles are large and the uniformity DR is low. After use, the metal surface of the parts cannot be completely covered, and ...

Problems solved by technology

However, the effective mist particles sprayed by the existing gas-phase antirust agents are relatively large. Generally, the preferred diameter is 30-50um, and some even reach 80-100um, and its uniformity DR is greater than 0.65. The mist particles are large and the uniformity DR is low. After use, the metal surface of the parts cannot be completely covered, and it cannot reach the fine seams of some parts or assemblies with complex structures and small pores, which makes the use effect poor; The diameter of the mist particles is large, and when it is used to prevent rust on the inner wall metal walls of some closed and narrow spaces, the mist particles cannot be effectively suspended, even if the suspension time is short, so the corrosion inhibition effect is not good, and the service life of the components is affected; so at present Most of the aerosols can not fully meet the needs of manufacturers, so it is necessary to improve
