Problems solved by technology

However, currently on the market, nitrite is mostly used as an anti-rust agent to prepare water-based stamping fluid. This type of anti-rust agent contains carcinogens. Direct contact with the human body is likely to cause skin cancer, and some anti-rust agents are likely to remain on the metal surface to form white spots. Anti-rust effect is poor

Embodiment 1

[0032] A metal water-based stamping fluid, its composition is (take 1000Kg water-based stamping fluid as an example):

[0033]

[0034]

[0035] A method for preparing metal water-based stamping fluid, the steps are as follows:

[0036] ⑴ Add metered distilled water into the reaction kettle, add lubricating extreme pressure agent and stir for 15 minutes;

[0037] (2) Add polyamide and triethanolamine in turn to the reaction kettle, and stir for 15 minutes;

[0038] (3) When the liquid phase in the reaction kettle is uniform and transparent, add benzotriazole, stir for 10 minutes, then add hydroxypropyl methylcellulose, stir for 30 minutes until the cellulose is completely dissolved;

[0039] (4) Finally, add triazine fungicides and three-dimensional siloxane defoamers, stir for 10 minutes, and stop stirring.

Embodiment 2

[0041] A metal water-based stamping fluid, its composition is (taking 1000Kg water-based rust inhibitor as an example):

[0042]

[0043] The steps of its preparation method are the same as in Example 1.

[0044] Mechanism of action of the present invention:

[0045] The first is to add lubricating extreme pressure agent and polyamide into the water to form the body of the stamping fluid. The added triethanolamine provides a stable pH value and plays a synergistic anti-rust effect with polyamide; benzotriazole synergistically prevents rust with anti-rust agent In addition to the effect of rust, it also protects copper against corrosion. Triazine fungicides prevent stamping fluid from corrupting and inhibit the growth of bacteria; hydroxypropyl methylcellulose assists in film formation and increases The thickening, lubricating and dispersing functions enable the stamping fluid to remain evenly on the metal surface, and the stamping effect can be optimized through the above ...

Abstract

The invention relates to metal water-based stamping liquid and a preparation method of the metal water-based stamping liquid. The metal water-based stamping liquid comprises the components by weight: 3-5% of lubricating extreme pressure agent, 2-4% of polyamide, 3-4% of triethanolamine, 0.1-0.2% of triazole fungicide, 0.1-0.5% of benzotriazole, 0.2-0.4% of hydroxypropyl methylcellulose, 0.05-0.1% of three-dimensional siloxane defoaming agent and the balance of distilled water. The preparation method comprises the main steps of: firstly, adding the distilled water, and then, orderly adding the lubricating extreme pressure agent, polyamide, triethanolamine, triazole fungicide, benzotriazole, hydroxypropyl methylcellulose and three-dimensional siloxane defoaming agent to mix. The action mechanism provided by the invention is simple and scientific; punch forming and anti-dusting effects of the metal achieve the optimal state by synergistic effect of the components; the water-based stamping liquid contains the triazole fungicide, so that decaying of the stamping liquid in storing and working processes can be effectively prevented; and the hydroxypropyl methylcellulose can assist film forming, and the fluid friction resistance is reduced, so that the water-based stamping liquid better protects the metal in the metal stamping and molding processes, and the anti-dusting time is more effectively increased after a workpiece is processed.

Description

technical field [0001] The invention belongs to the field of metal stamping, in particular to a metal water-based stamping fluid and a preparation method thereof. Background technique [0002] Water-based stamping fluid is a compound composed of water-based lubricating extreme pressure agent, water-based anti-rust agent and other components. It is mainly used in punch drawing, punching, punching, bending, etc. And other processes, good lubricating performance, especially good cooling performance, good permeability, long anti-rust time between processes, less environmental pollution, safe production, is the current development direction of stamping fluids. However, currently on the market, nitrite is mostly used as an anti-rust agent to prepare water-based stamping fluid. This type of anti-rust agent contains carcinogens. Direct contact with the human body is likely to cause skin cancer, and some anti-rust agents are likely to remain on the metal surface to form white spots. ...
