preparation example Construction

[0032] The present invention also provides a preparation method of a neutral degreasing and derusting cleaning agent suitable for the production cycle of pre-painting treatment, comprising the following steps: (1) mixing organic acid and water evenly; (2) adding corrosion inhibitor In the mixed solution of step (1), fully stir until the solution is clear and transparent; (3) join the chelate compound in the mixed solution of step (2), fully stir until the solution is clear and transparent; (4) in step ( 3) In the mixed solution, add inorganic salts to adjust the pH to 6.5-7.5; (5) After the mixed solution in step (4) is fully stirred until the solution is clear and transparent, and the temperature of the solution is cooled to below 50°C, add a surfactant , and then stir well to complete the preparation.

[0033] The reference technical indicators of the neutral degreasing and derusting cleaning agent described in the embodiment of the present invention in line with the product...

Embodiment 1

[0041] Prepare 100kg of a cleaning agent for degreasing and rust removal according to the production rhythm of pre-painting treatment. Its raw materials are as follows: inorganic salt KOH 10kg, organic acid citric acid 25kg, chelate phytic acid 8kg, surfactant fatty alcohol Polyoxyethylene ether (n=7) 1kg, surface active sodium stearate 1kg, corrosion inhibitor organic amine ester TPP 1kg, and the balance is water. Weigh each raw material with the above weight, first mix the organic acid and water, fully stir evenly, then add the corrosion inhibitor, fully stir until the solution is clear and transparent, then add the chelate compound, fully stir until the solution is clear and transparent, then add Inorganic salt, adjust pH=6-7, stir well until the solution is clear and transparent, after the temperature of the solution is cooled to below 50°C, finally add the surfactant, and then the above-mentioned suitable for pre-painting treatment production cycle can be obtained. Rust c...

Embodiment 2

[0043] Prepare 100kg of a cleaning agent for degreasing and derusting that meets the production rhythm of pre-painting treatment of the present invention, and its raw material composition is as follows: inorganic salt K 2 CO 3 20kg, organic acid tartaric acid 35kg, chelate HEDP 12kg, surfactant fatty alcohol polyoxyethylene ether (n=7) 3kg, surface active sodium stearate 2kg, corrosion inhibitor organic amine ester TPP 3kg, and the balance is water. Weigh each raw material with the above weight, first mix the organic acid and water, fully stir evenly, then add the corrosion inhibitor, fully stir until the solution is clear and transparent, then add the chelate compound, fully stir until the solution is clear and transparent, then add Inorganic salt, adjust pH=6-7, stir well until the solution is clear and transparent, after the temperature of the solution is cooled to below 50°C, finally add the surfactant, and then the above-mentioned suitable for pre-painting treatment produ...

Abstract

The invention discloses neutral oil and rust removing detergent used for agreeing with the coating pretreatment production takt and a preparation method and relates to the technical field of metal surface oil and rust removing treatment. The neutral oil and rust removing detergent used for agreeing with the coating pretreatment production takt and the preparation method comprise the following components including, by weight percentage, 5-25% of inorganic salt, 20-40% of organic acid, 5-15% of chelate, 1-5% of surface active agent, 0.5-5% of corrosion inhibitor and the balance water. Accordingto the neutral oil and rust removing detergent, the oil and rust removing speed is high, the existing production takt is not influenced, in the coating application, on the premise of not increasing investment of large equipment or not changing the existing production takt, an original degreasing agent is directly replaced by the neutral oil and rust removing detergent, the existing degreasing working procedure is compatible with the rust removing function, the pretreatment appearance of a metal piece and the appearance of paint films are improved greatly, the adhesive force and the corrosion resisting performance of the paint films are improved remarkably, and the whole coating quality is improved.

Description

technical field [0001] The invention relates to the technical field of metal surface degreasing and derusting treatment, in particular to a neutral degreasing and derusting cleaning agent suitable for the production cycle of pre-painting treatment and a preparation method thereof. Background technique [0002] The cleaning of the surface of metal parts is particularly important in the field of pre-painting treatment. In many industries, such as home appliances, automobiles, shipbuilding, machinery, electronics and other industries, before electroplating, powder spraying, anticorrosion or other surface treatment, the workpiece is degreased, degreased, derusted and cleaned of various common oil stains, lubricants, etc. . [0003] In the field of pre-painting treatment, due to the impact of the previous punching and welding process, there will be more or less oxide scales on the surface of metal parts, which will affect the coverage of the subsequent paint film and affect the ...
