Problems solved by technology

However, the hydrophobic and oleophobic properties of the above-mentioned anti-fingerprint protective film make it impossible for ordinary solvents to be compatible with the surface of the workpiece during the deplating rework process of the workpiece, which makes the deplating rework process cause certain difficulties
In the prior art, perfluoropolyether methacrylic resin is usually used to deplate the anti-fingerprint protective film, which is costly and complicated in post-treatment process

Embodiment 1

[0019] Embodiment 1: configuration 1L has the stripping solution that volume fraction is the stripping agent of 10%, wherein, the solvent of described stripping solution is water, and described stripping agent is 5% fluorosurfactant by mass fraction , ammonium bifluoride with a mass fraction of 5%, glycerin with a mass fraction of 15% and water with a mass fraction of 75%. At 20° C., the workpiece to be stripped is immersed in the stripping solution for about 120 seconds. After dipping the workpieces are washed and dried.

Embodiment 2

[0020] Embodiment 2: configuration 1L has the stripping solution that volume fraction is 10% stripping agent, wherein, the solvent of described stripping solution is water, and described stripping agent is 10% fluorosurfactant by mass fraction , ammonium bifluoride with a mass fraction of 7%, glycerin with a mass fraction of 10% and water with a mass fraction of 73%. At 20° C., the workpiece to be stripped is immersed in the stripping solution for about 140 seconds. After dipping the workpieces are washed and dried.

Embodiment 3

[0021] Embodiment 3: configuration 1L has the stripping solution that volume fraction is 10% stripping agent, wherein, the solvent of described stripping solution is water, and described stripping agent is 10% fluorosurfactant by mass fraction , ammonium bifluoride with a mass fraction of 7%, glycerin with a mass fraction of 10% and water with a mass fraction of 73%. At 22° C., the workpiece to be stripped was immersed in the stripping solution for about 140 seconds. After dipping the workpieces are washed and dried.

Abstract

The invention provides a deplating agent. A to-be-deplated workpiece with the surface being plated with a fingerprint-proof film can be deplated through the deplating agent, the workpiece is made of glass or silicon, or a silicon dioxide film layer is plated between the workpiece and the fingerprint-proof film, and the deplating agent is prepared from the components in percentage by mass: 5-15% ofa surfactant, 5-8% of ammonium bifluoride, 5-20% of a solvent and 65-75% of water. The invention further provides a deplating method using the deplating agent. According to the deplating agent and the deplating method using the same, the fingerprint-proof film attached to the surface of the workpiece is quickly removed.

Description

technical field [0001] The invention relates to a stripping agent, in particular to a stripping agent for stripping an anti-fingerprint protective film and a stripping method using the stripping agent. Background technique [0002] In the process of coating production, the workpiece is often coated with an anti-fingerprint protective film, such as AF film, on the outermost layer of the coating. The above-mentioned anti-fingerprint protective film can effectively prevent fingerprints, oil, water and dust, and has very high light transmittance. However, the hydrophobic and oleophobic properties of the above-mentioned anti-fingerprint protective film make it difficult for ordinary solvents to be compatible with the surface of the workpiece during the deplating and reworking process of the workpiece, which makes the deplating and reworking process difficult. In the prior art, perfluoropolyether methacrylic resin is usually used to deplate the anti-fingerprint protective film, w...
