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 effecti

Example Embodiment

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

[0027] The working principle of the present invention is that the cleaning agent can be completely dissolved in water, can effectively remove various pollutants remaining on the surface of the metal material under the action of ultrasound, and can clean the residue on the surface of the metal material during the ultrasonic washing process Removal of chemicals and other impurities, and then spraying and drying to make the surface of the metal material clean. Observed through a magnifying glass, there is 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 solubilizer, and its struc...

Example Embodiment

[0030] Example 1: Prepare 1 kg of cleaning agent.

[0031] Weigh 3% sodium peroxyphosphate and 10% polyoxyethylene fatty alcohol ether with a degree of polymerization of 20 (commercial name: Ping Pingjia, structural formula: RO-(CH2CH2O)nH), 5% 5% triethylamine, 6% n-hexane and 2% polyurea, the remainder is pure water for use.

[0032] Add hexane, polyoxyethylene fatty alcohol ether, sodium peroxyphosphate, polyurea and triethylamine in the aforementioned proportions to pure water, and 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 a cleaning agent for cleaning, add 10 to 20 times deionized water to the cleaning agent and put it in the first tank, heat it to 60 to 80°C, and put the metal material to be cleaned in the first tank. Ultrasound, the ultrasonic frequency is controlled at 18KHz to 80KHz, and the ultrasonic t...

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...
