Embodiment 1

[0020]

[0021] Mix the raw materials in the above weight ratio directly, heat to 80°C with a heating tube, mechanically stir until barium petroleum sulfonate, benzotriazole tributylamine, lead naphthenate, and vaseline are completely dissolved in diesel oil, and collect to obtain anti-corrosion Rust pulls deep oil.

[0022] In the production, the steel parts with a bending thickness of 3mm and the material of Q235 were used with this anti-rust deep drawing oil. There was no crack or obvious scratch in the bending part, and the product was naturally placed in the production workshop for 10 days without rust.

[0023] Contrast: When the same steel piece is bent with engine oil as lubricating oil, there is no crack and no obvious abrasion at the bent part, but the product rusts after being placed naturally in the production workshop for 2 days.

Embodiment 2

[0025]

[0026] Mix the raw materials in the above weight ratio directly, heat to 90°C with a heating tube, mechanically stir until barium petroleum sulfonate, benzotriazole tributylamine, lead naphthenate, and vaseline are completely dissolved in diesel oil, and collect to obtain anti-corrosion Rust pulls deep oil.

[0027] In production, 200 pieces of steel parts with a thickness of 0.5mm and a material of 18 (deep drawing of small parts) were used for this anti-rust deep drawing oil. There was no crack at the bottom of the drawn part and no scratches at the drawn part. The product No rust was found in the production workshop after 10 days of natural storage.

[0028] Contrast: Using machine oil as lubricating oil to deep draw the same steel parts, 5 out of 200 pieces cracked, and the products rusted after 2 days of natural storage in the production workshop.

Embodiment 3

[0030]

[0031] Mix the raw materials in the above weight ratio directly, heat to 90°C with a heating tube, mechanically stir until barium petroleum sulfonate, benzotriazole tributylamine, lead naphthenate, and vaseline are completely dissolved in diesel oil, and collect to obtain anti-corrosion Rust pulls deep oil.

[0032] During production, 200 steel pieces (large pieces) with a thickness of 0.3mm and 08F material were drawn with this anti-rust deep drawing oil. No cracks and scratches appeared on the drawn parts, and no bulges appeared on the bottom of the drawn parts. The product has been placed in the production workshop for 10 days without any rust.

[0033] Contrast: When the same steel piece is drawn with engine oil as lubricating oil, 7 out of 200 pieces have bulges at the bottom of the drawn piece, and the product rusts after being placed naturally in the production workshop for 2 days.

Abstract

The invention belongs to the fields of hardware product lubrication and anti-rust technologies, and discloses anti-rust drawing oil and a preparation method thereof. The drawing oil consists of the following components in percentage by weight: 7 percent of barium petroleum sulfonate, 1 percent of benzotriazole tri-n-butylamine, 1-2 percent of lead naphthenate, 15-25 percent of vaseline and 65-76 percent of diesel oil. The drawing oil can meet the requirement of lubrication during stamping (such as drawing or bending), and can also meet the anti-rust requirement between the steps; the anti-rust period of a stamped workpiece is over seven days; and rust protection between the steps is not required additionally. The preparation method comprises the steps of: directly mixing the raw materials; heating through a heating tube; mechanically stirring; and collecting. The preparation method has the advantages of easiness, convenience, environmental friendliness, low cost and easiness in implementation.

Description

technical field [0001] The invention belongs to the technical field of lubrication and antirust of hardware products, relates to a chemical oil, in particular to an antirust drawing oil used for the lubrication of hardware products during deep drawing and bending and antirust between processes and a preparation method thereof. technical background [0002] When stamping metal products (such as deep drawing, bending, etc.), it is necessary to apply drawing oil on the workpiece and mold to play a lubricating role to prevent wear of the mold and workpiece, and prevent defects such as pull-through of the workpiece. Ordinary deep drawing oil has no anti-rust effect, and the workpiece is easy to rust in hot and humid weather. Most hardware products need to be electroplated. Even if the rust is removed after rusting, spots will be left on the surface of the workpiece, which not only affects the appearance, but also affects the antirust performance of the workpiece after electroplat...
