Problems solved by technology

[0003] In order to ensure the deplating effect of the electroplating layer, it is necessary to select a suitable deplating solution, but the deplating solution contains some substances with strong adsorption to glass (such as potassium ferricyanide, etc.), ordinary cleaning agents (alkaline cleaning agents, etc.) ) are difficult to wash off these substances, resulting in dirty products
At present, the existing cleaning agents cannot clean the residual dirt after deplating, and cannot meet the yield requirements
At the same time, the traditional alkaline cleaning agent needs to be carried out at high temperature, and the corrosive gas is easy to volatilize, which will affect the environment and operators

Embodiment approach

[0054] As a preferred embodiment, the cleaning agent comprises the following components by mass percentage: 5-8% of salicylic acid or its derivatives, 12-14% of sulfamic acid or its derivatives, 6-10% of an oxidizing agent, 0.5-1% of complexing agent, 1-3% of penetrant and the balance of water.

[0055] As a further preferred embodiment, the cleaning agent includes the following components by mass percentage: 5-6% of salicylic acid or its derivatives, 12-13% of sulfamic acid or its derivatives, 6-8% of an oxidant, Mixture 0.5-0.8%, penetrant 2-3% and balance water.

[0056] By further optimizing the concentration ratio of each component, the cleaning and decontamination effect is better.

[0057] In a preferred embodiment, the oxidizing agent is a persulfate, preferably ammonium persulfate.

[0058] In a preferred embodiment, the complexing agent is an aminocarboxylate, including sodium nitrilotriacetate (NTA), ethylenediaminetetraacetate (disodium or tetrasodium EDTA) or di...

Abstract

The invention discloses a cleaning agent for cleaning dirt after stripping an electroplated layer of glass, a cleaning method and an electronic product, and relates to the technical field of glass cleaning. The cleaning agent for cleaning the dirt after stripping the electroplated layer of the glass is prepared from the following components in percentage by mass: 4 to 8% of salicylic acid or a derivative thereof, 10 to 15% of amino sulfonic acid or a derivative thereof, 5 to 10% of oxidant, 0.5 to 1% of complexing agent, 1 to 3% of penetrant, and the balance of water. The cleaning method is that the glass is cleaned by the cleaning agent after the electroplated layer is stripped. The cleaning agent can solve the technical problem of the existing cleaning agent that residual dirt cannot bethoroughly cleaned after a product is subjected to stripping, and the yield requirement cannot be met. The cleaning agent has the advantages that the residual dirt on the glass can be effectively cleaned off after the electroplated layer is stripped by a stripping solution; after the cleaning agent is used for cleaning, the appearance of the glass is clean, the residual dirt is avoided, and the yield is high.

Description

technical field [0001] The invention relates to the technical field of glass cleaning, in particular, to a cleaning agent, a cleaning method and an electronic product for cleaning the dirt after the glass is stripped and electroplated. Background technique [0002] With the progress of society, 2D, 2.5D or 3D glass has been applied to various electronic products, and electroplating Logo on glass has also become a fashion, and the requirements for stripping and cleaning are also getting higher and higher. For example, the logo electroplating process for cover glass includes: electroplating (such as a composite film layer of silicon, titanium and chromium) - silk screen printing ink - stripping - cleaning - inspection, that is, a layer of electroplating is first coated on the glass, and then the pattern is screen printed. Selectively remove a part (remove the electroplating layer of the excess part of the logo), thereby giving the coating layer a patterning effect to form the ...
