Technical field

The present invention relates to a kind of strip agent, carry out the strip agent of strip more particularly to a kind of pair of anti-fingerprint protective film and make With the strip method of the strip agent.

Background technique

Workpiece often plates one layer of anti-fingerprint protective film in the outermost layer of plated film, such as AF film during plated film produces.On Stating anti-fingerprint protective film can effective anti-fingerprint, grease proofing, waterproof and dust protection and very high light transmittance.However, above-mentioned Anti-fingerprint protective film is hydrophobic and the characteristic of oleophobic, makes usual vehicle in the strip heavy industry processing procedure of workpiece can not be with workpiece surface parent With so that strip heavy industry is caused certain difficulty.In the prior art usually using perfluoropolyether methacrylic resin to anti-fingerprint Protective film carries out strip, at high cost, and aftertreatment technology is complicated.

Summary of the invention

In consideration of it, effectively carrying out the strip agent of strip and moving back using the strip agent to fingerprint proof membrane it is necessary to provide a kind of Electroplating method.

A kind of strip agent, fingerprint proof membrane can be coated with to surface carries out strip to strip workpiece, and the workpiece is glass It is coated with silica coating between glass material, siliceous material or workpiece and fingerprint proof membrane, quality point is contained in the strip agent The solvent that ammonium acid fluoride that surfactant, the mass fraction that number is 5%-15% are 5%-8%, mass fraction are 5%-20% And mass fraction is the water of 65%-75%.

A kind of strip method using the strip agent comprising will be impregnated in strip workpiece with the strip agent In strip solution；The workpiece is washed and dried after dipping.

Above-mentioned strip agent can efficiently and quickly remove the fingerprint proof membrane being attached to strip workpiece surface, improve workpiece Strip and heavy industry efficiency.

Detailed description of the invention

Fig. 1 is that workpiece uses the appearance photo deck watch before and after the different strip agent progress strip in embodiment 1-5.

Fig. 2 is the variation table for the water droplet contact angle that workpiece is carried out using the different strip agent in embodiment 1-5 before and after strip.

Specific embodiment

Contain in the strip agent of an of the invention better embodiment: selected from for the one or more combination of surfactant, Ammonium acid fluoride, solvent and water.

The surfactant is fluorosurfactant, can be selected from one of FC-4430, FC-430, FSN-100 Or it is several.Mass fraction of the surfactant in the strip agent can be 5%-15%.The surfactant is used In the wetability and permeability that improve the strip agent.

Mass fraction of the ammonium acid fluoride in the strip agent can be 5%-8%.The ammonium acid fluoride is moved back described It plates and is used as corrosion reagent in agent, to corrode to the nature of glass, siliceous or silica material.

The solvent can be selected from one of ethylene glycol, glycerol or several.Matter of the solvent in the strip agent Measuring score can be 5%-20%.The solvent is used to improve the solubility of the surfactant of the strip agent.

Mass fraction of the water in the strip agent can be 65%-75%.

In the present embodiment, the strip agent be suitable for surface be coated with fingerprint proof membrane to strip workpiece.The fingerprint proof membrane For perfluoropolyether film plating layer, the workpiece is to be coated with two between vitreous material, siliceous material or workpiece and fingerprint proof membrane Membranous layer of silicon oxide.Fluorine element surface-active in the strip agent can be permeated and be soaked to the fingerprint proof membrane, to make Ammonium acid fluoride in strip agent infiltrates into the surface of workpiece or the silica surface of workpiece and to workpiece surface or described Silica surface carries out corrosion dissolution, and then the fingerprint proof membrane is removed workpiece and realizes the strip to fingerprint proof membrane.

A kind of strip method using above-mentioned strip agent comprising following steps:

It will be impregnated in the strip solution for the strip agent for being 10% with volume fraction to strip workpiece, be 20 in temperature It is impregnated -180 seconds 120 seconds at DEG C -25 DEG C；

The workpiece is washed and dried after dipping.

It is described further below in conjunction with specific embodiment.
