Problems solved by technology

The common disadvantages of this kind of dehydration antirust oil are: 1. The dehydration speed is slow. For example, the steel components with water attached to the surface are soaked in this kind of dehydration antirust oil, and the time to remove the water film takes 10 to 45 minutes; 2. 1. The anti-rust period is short. After the general steel parts are treated with this kind of dehydration anti-rust oil, the anti-rust period is only one month; 3. The dehydration speed and the anti-rust period cannot be taken into account. is short, and the variety with long anti-rust period has a slow dehydration rate.

Abstract

A dewatering antirust oil is prepared from mineral oil (85-93 mass%), antirust additive (4-8), dewatering additive (1-5), antioxidizing agent (0.5-2) and other additives (0.1-0.5). Iron and steel objects after treated have their surface adhered with antirust oil film. Its advantages include high dewatering speed (2-5 min) and long antirusting period (1-2 years).

Description

1. Technical field: [0001] The invention belongs to the technical field of metal surface treatment, in particular to metal surface dehydration antirust oil and its preparation technology. 2. Background technology: [0002] The currently commercially available metal dehydration antirust oil is usually compounded by mineral oil, dehydration additives, antirust additives, etc., wherein the mineral oil is usually kerosene with a mass fraction of about 90%, and the antirust additive is usually barium petroleum sulfonate , its mass fraction is 2 to 3%, and the mass fraction of other additives is 7 to 8%. The common disadvantages of this kind of dehydration antirust oil are: 1. The dehydration speed is slow. For example, the steel components with water attached to the surface are soaked in this kind of dehydration antirust oil, and the time to remove the water film takes 10 to 45 minutes; 2. 1. The anti-rust period is short. After the general steel parts are treated with this kind...
