Problems solved by technology

[0002] In the cleaning industry, especially in the cleaning of workpieces at room temperature, the parts will be corroded soon after cleaning, especially the water-based room temperature anti-rust spray cleaning agent. After cleaning, the workpieces cannot meet the cleaning quality standards. The workpiece is corroded and has no anti-rust effect, and the workpiece begins to change color after being placed for a period of time after cleaning

Embodiment 1

[0020] A water-based normal temperature anti-rust spray cleaning agent, its raw material composition and weight percentage are respectively:

[0021]

[0022] A preparation method of a water-based normal temperature anti-rust spray cleaning agent, the steps are as follows:

[0023] (1) Add the reaction amount of water into the reaction kettle, add the reaction amount of HEDP-4NA and sodium metasilicate pentahydrate at 25-40°C, keep the reaction for 20 minutes, then add the surfactant H-381 to keep the reaction for 20 minutes Minutes to get solution A;

[0024] (2) Add triethanolamine, monoethanolamine, dibasic acid, and benzotriazole to the reaction kettle until the reaction is complete. During the reaction, keep the temperature of the reaction kettle at 40-60°C and keep stirring for 3 hours until the solution is clear and transparent. Get solution B;

[0025] (3) The above two solutions A and B are mixed and reacted to a transparent liquid, which becomes a normal tempera...

Embodiment 2

[0029] A water-based normal temperature anti-rust spray cleaning agent, its raw materials and weight percentages are respectively:

[0030]

[0031] The preparation method of this embodiment is the same as that of Example 1.

[0032] Application example: the concentration of the first tank according to the ratio of water and normal temperature anti-rust spray cleaning agent 20:1 (add the normal temperature anti-rust spray cleaning agent of Example 2), the normal temperature anti-rust spray cleaning agent of Example 2 and water Put the metal parts to be cleaned (aluminum, copper and assemblies) in the spray cleaning equipment, adjust the spray pressure to 0.3MPa, control the cleaning temperature at 25-30°C, and adjust the running speed of the spray cleaning equipment assembly line , start spray cleaning, so that the effective spray time of metal parts is controlled at 2 minutes, and the second tank is sprayed and rinsed with clean water for 2 minutes, and then dried with hot...

Abstract

The invention relates to a water-based normal-temperature rustproof spray cleaning agent. The cleaning agent comprises the following raw materials in percentages by weight: 20-25% of HEDP-4NA ((1-hydroxyethylidene)bis-phosphonic acid tetrasodium salt), 0.5-5% of sodium metasilicate, 5-8% of triethanolamine, 1-5% of monoethanolamine, 2-3% of binary acid, 3-8% of surfactant H-381, 0.2-1% of benzotriazole, and the balance of water. The cleaning agent disclosed by the invention is simple in application method, and obvious in effect; the cleaning agent can be used in high-pressure spray, ultrasonic and soaking modes, and is less in application amount; and the cleaning agent does not corrode metals, and can be used without heating at normal temperature, therefore, the cleaning agent is simple and safe in application, saves energy and working time, and improves the working efficiency.

Description

technical field [0001] The invention belongs to the field of chemical cleaning and antirust, and relates to an antirust cleaning agent, in particular to a water-based room temperature antirust spray cleaning agent and a preparation method thereof. Background technique [0002] In the cleaning industry, especially in the cleaning of workpieces at room temperature, the parts will be corroded soon after cleaning, especially the water-based room temperature anti-rust spray cleaning agent. After cleaning, the workpieces cannot meet the cleaning quality standards. The workpiece is corroded and has no anti-rust effect, and the workpiece begins to change color after being placed for a period of time after cleaning. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the existing technology, and provide a safe, environmentally friendly, energy-saving, normal temperature anti-rust spray cleaning agent and its preparation method ...
