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

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 in particular relates to a water-based cleaning agent and its preparation method and application. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on some metal surfaces using the principle of electrolysis. The special application of electroforming as electroplating is to use the original mold made in advance according to the required shape as the cathode, use the electroforming material as the anode, put them together in the same metal salt solution as the anode material, and then pass through direct current. Under the action of the original mold, the metal electroforming layer will be gradually deposited on the surface of the original mold. When the required thickness is reached, it will be taken out of the solution, and the electroforming layer will be separated from the original mold to obtain a metal copy corresponding ...
