Problems solved by technology

[0005] In view of this, the technical problem to be solved in the present invention is to provide an alkaline non-scratch deplating solution and a deplating method. After deplating, the product surface has high transparency and will not cause problems such as rough product surface and new scratches.
[0008] In the deplating solution provided by the invention, the main agent is a single medium system based on ammonia water (replacing inorganic alkali, inorganic salt and organic solvent), the use process is less harmful to the operator, and the waste water produced is easy to handle, which solves the problems in the prior art. The chemical reaction of organic solvent is fast, easy to volatilize, and the technical problem of poor penetration of faded ink

Embodiment 1～4

[0031] In terms of mass percentage, the ratio of the deplating agent is as follows: industrial ammonia 25%, diethylene glycol dibutyl ether 25%, benzyl alcohol 10%, butyrolactone 8%, triethylene glycol 2.5%, JFC 12%, the balance It is water; the deplating temperature is 95℃, and the deplating time is 2min. The parts were stripped to observe whether the stripping effect had any influence, and whether there was damage, bluing and fogging on the surface of the product. The results are shown in Table 1.

[0032] Wherein, the stripped parts in Examples 1-2 are glass sheets sprayed with AR protection oil on the surface; the stripped parts in Examples 3-4 are glass sheets with AR protection oil screen-printed on the surface.

[0034]

Embodiment 5～8

[0036] In terms of mass percentage, the ratio of the stripping agent is as follows: industrial ammonia 25%, diethylene glycol dibutyl ether 22%, benzyl alcohol 8%, butyrolactone 6%, triethylene glycol 2.0%, JFC 10%, the balance It is water; the deplating temperature is 95℃, and the deplating time is 3min. The parts were stripped to observe whether the stripping effect had any influence, whether there was any damage to the surface of the product, bluish and foggy. The results are shown in Table 2.

[0037] Among them, the stripped parts in Examples 5-6 are glass sheets sprayed with AR protection oil on the surface; the stripped parts in Examples 7-8 are glass sheets with AR protection oil silk-screened on the surface.

Embodiment 9～12

[0041] In terms of mass percentage, the ratio of the stripping agent is as follows: industrial ammonia 30%, diethylene glycol dibutyl ether 20%, benzyl alcohol 5%, butyrolactone 4%, triethylene glycol 2.0%, JFC 8%, the balance It is water; the deplating temperature is 95℃, and the deplating time is 4min. The parts are stripped to observe whether the stripping effect has any influence, whether there is damage to the product surface, bluish and foggy, and the results are shown in Table 3.

[0042] Among them, the stripped parts in Examples 9-10 are glass sheets sprayed with AR protection oil on the surface; the stripped parts in Examples 11-12 are glass sheets with AR protection oil screen printed on the surface.

Abstract

The invention provides an alkaline non-scratch deplating solution, which in mass percentage comprises: ammonia water 25%-30%; diethylene glycol dibutyl ether 20%-25%; benzyl alcohol 5%-10%; Butyrolactone 4% to 8%; triethylene glycol 2% to 2.5%; JFC 8% to 12%; the balance of water. The above-mentioned stripping solution provided by the present invention can strip the ink on the product without adding new scratches to the product during the stripping process, without regrinding. , reduce the company's rework cost, improve the secondary yield, and at the same time, the stripping time is short, and the stripping yield is high, which can effectively protect the product's appearance transparency and roughness. The de-plating solution is an environmentally friendly agent, does not cause damage to the human body and the environment, has little environmental pollution, and has high industrial application value.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an alkaline non-scratch stripping solution and a stripping method. Background technique [0002] Deplating solution is a reagent that removes the ink on the surface of the product, while protecting the transparency, unevenness and roughness of the product surface without causing scratches. [0003] The existing deplating solution is a strong alkaline agent, which will burn the human body and pollute the environment. After deplating, the surface of the product is rough, the appearance transparency is lost, and there is a bluish and foggy appearance, and the product is newly scratched, and it needs to go through the mill to return the ink. . [0004] At present, the yield rate of 3D glass products rework and stripping is low, and they are basically stripped with strong alkaline agents. After stripping, the surface of the product is scratched, and it needs to go through t...
