Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome that the water-based metal cleaning agent in the prior art can only remove oil stains, but cannot remove residual release agent and change the wettability of the metal surface to be plated, thus requiring multiple cleanings Defects on the metal surface to be plated, thereby providing a water-based metal cleaning agent that can realize the removal of oil stains and residual release agents on the metal surface to be plated by one cleaning, and improve the hydrophilicity of the metal surface to be plated, and Its preparation method and application

Embodiment 1

[0032] This embodiment provides a water-based cleaning agent, including 1.5g AEO-9, fatty acid methyl ester ethoxylate sulfonate (FMES) 8g, polyoxyethylene alkylphenol ether 1g, and anhydrous sodium metasilicate 10g, 2g sodium hydroxide and 977.5g deionized water, put 977.5ml deionized water into the container, heat to 40℃, add 1.5g AEO-9 into the container and stir for 10min, then add 8g FMES into the container After stirring and stirring for 15 minutes, 1 g of polyoxyethylene alkyl phenol ether, 10 g of anhydrous sodium metasilicate and 2 g of sodium hydroxide were added in sequence. After stirring for 10 minutes, a water-based metal cleaning agent was obtained.

Embodiment 2

[0034] This embodiment provides a water-based cleaning agent, including 15g AEO-9, 1g FMES, 3g polyoxyethylene alkylphenol ether, 7g anhydrous sodium metasilicate, 15g sodium hydroxide and 959g deionized water. Put 959ml of ionized water into the container, heat it to 90℃, add 15g AEO-9 into the container and stir for 20min, then add 1g FMES into the container and stir, after stirring for 10min, add 3g polyoxyethylene alkyl phenol ether successively. 7g of sodium metasilicate water and 15g of sodium hydroxide were stirred for 15 minutes to obtain water-based metal cleaning agent.

Embodiment 3

[0036] This embodiment provides a water-based cleaning agent, including 4g AEO-9, 3g FMES, 4g polyoxyethylene alkylphenol ether, 3g anhydrous sodium metasilicate, 9g sodium hydroxide and 977g deionized water. Put 977ml of ionized water into the container, heat it to 50℃, add 4g AEO-9 into the container and stir for 12min, then add 3g FMES into the container and stir, after stirring for 13min, add 4g polyoxyethylene alkylphenol ether successively, 3g of anhydrous sodium metasilicate and 9g of sodium hydroxide were stirred for 12 minutes to obtain a water-based metal cleaning agent.

Abstract

The invention belongs to the technical field of cleaning agents, and particularly relates to a water-based cleaning agent and a preparation method and application thereof. The water-based cleaning agent is prepared from a surfactant, a pH regulating agent, water and auxiliary agents, and the auxiliary agents comprise anhydrous sodium metasilicate and polyoxyethylene alkylation ether; and the water-based cleaning agent is particularly prepared from, by the total mass of the water-based cleaning agent, 0.25%-2.3% of the surfactant, 0.1%-0.4% of polyoxyethylene alkylation ether, 0.3%-1% of anhydrous sodium metasilicate and 0.2%-1.5% of the pH regulating agent. The preparation method of the water-based cleaning agent comprises the steps that the surfactant, the auxiliary agents and the pH regulating agent are added into heated water and stirred to be completely dissolved. According to the water-based cleaning agent, the purpose of removing oil stains and a release agent on the surface of to-be-plated metal can be achieved through one-step cleaning, and meanwhile the hydrophilia of the surface of the to-be-plated metal can be improved.

Description

Technical field [0001] The invention belongs to the technical field of cleaning agents, and specifically relates to a water-based cleaning agent and a preparation method and application thereof. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. Electroforming is a special application of electroplating. It uses the original mold made in the required shape as the cathode, and the electroforming material is used as the anode. They are put into the same metal salt solution as the anode material, and then direct current is applied. Under the action of, the metal electroformed layer will gradually deposit on the surface of the original mold. When it reaches the required thickness, it will be taken out from the solution, and the electroformed layer will be separated from the original mold to obtain a metal copy corresponding to the shape of the original mold....
