Problems solved by technology

[0004] Most of the existing cleaning agents for metal materials are solvent-based or phosphorus-containing water-based cleaning agents. The disadvantages of these cleaning agents are that the cleaning effect is not ideal, and various pollutants such as processing debris and dust particles on the metal surface cannot be effectively removed. , the metal surface after cleaning is prone to black surface layer, which brings troubles to subsequent processing, especially for the processing of precision components; it is also highly corrosive to equipment and increases equipment costs; the cleaning time is long, and it takes 10 to 30 minute cleaning time

preparation example Construction

[0026] The preparation method of the metal material surface cleaning agent of the present invention is to add the oxidizing agent, pH regulator, surfactant, solubilizer, and defoamer in the aforementioned proportions into pure water and heat them to 40 to 60°C and stir to dissolve completely, and then obtain finished product.

[0027] The working principle of the present invention is that the cleaning agent can be completely dissolved in water, and can effectively remove various pollutants accumulated on the surface of metal materials under the action of ultrasound, and can clean the residues on the surface of metal materials during the ultrasonic washing process. Remove solvents and other impurities, and then spray and dry to clean the surface of the metal material. Observed through a magnifying glass, there are no obvious oil stains, dust particles and other pollutants on the surface.

[0028] The metal material surface cleaning agent of the present invention contains a solu...

Embodiment 1

[0030] Embodiment 1: Prepare 1 kilogram of cleaning agent.

[0031] Take by weighing respectively the sodium peroxyphosphate that the weight of preparation cleaning agent is 3%, polyoxyethylene fatty alcohol ether (commercial name: Pingpingjia, structural formula is: RO-(CH2CH2O)n-H) that 10% polymerization degree is 20, 5% triethylamine, 6% n-hexane and 2% polyurea, and the balance is pure water for later use.

[0032] Add hexane, polyoxyethylene fatty alcohol ether, sodium peroxyphosphate, polyurea and triethylamine in the pure water respectively, then heat to 40°C and stir until completely dissolved to obtain the finished cleaning agent. The specific gravity of the cleaning solution is 1.030g / cm 3 , PH value is 12.5.

[0033] When cleaning, step (1): Take the cleaning agent for cleaning, add 10 to 20 times of deionized water to the cleaning agent and put it into the first tank, heat it to 60 to 80°C, put the metal material to be cleaned into the first tank, and carry out ...

Abstract

The invention provides a cleaner for the surface of a metal material, comprising oxidizing agent, a pH regulator, surface active agent, solubilizer, defoaming agent and purified water; wherein, the weight percentage of the oxidizing agent is 0.5 percent to 5 percent, the weight percentage of the pH regulator is 3 percent to 12 percent, the weight percentage of the surface active agent is 5 percent to 15 percent, the weight percentage of the solubilizer is 1 percent to 10 percent, the weight percentage of the defoaming agent is 2 percent to 7 percent and the rest is purified water; the cleaner is an alkaline water-soluble cleaner, has good cleaning effect to pollutants remained on the surface of the metal material, has low corrosion without corrosion equipment, is not easy to damage the surface of the metal material, meets the requirements of environment protection and has reasonable formulation design, simple preparation technique and low cost; and the cleaned waste liquid is convenient to be treated and discharged.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a metal material surface cleaning agent. Background technique [0002] When preparing metal products, cleaning the materials before processing is an important process in the production process. For high-tech products, cleaning the processed materials is a key process. The cleanliness of processed materials is related to the performance, quality, service life and reliability of products, especially high-tech products have the characteristics of high performance, high reliability, high precision, high integration and miniaturization, and are very sensitive to cleanliness , Minor pollution will have a serious impact on the performance, quality, service life and reliability of the product. Therefore, improving the cleanliness of processed materials has become an important topic to improve product performance, quality, service life and reliability. [0003] Metal materials need to be cleaned befo...
