Technical field

The invention belongs to chemical coating scavenger technical fields, and in particular to a kind of preparation method of excessive glue scavenger and answer With.

Background technique

In optical design, cemented doublet is often used to reduce lens set number, reduces assembly difficulty.Eyeglass is in gluing procedures In, adhesive must be slightly excessive to ensure not occur bubble between eyeglass.Eyeglass side can be spilt into after extra adhesive bonding Face even lens surface, influences the assembly of eyeglass, it is necessary to try to remove.Traditional excessive glue scavenger generallys use volatile organic Solvent and cosolvent and surfactant composition, although effect is preferable, because wherein comprising volatile organic solvent etc. Ingredient, there are pollution environment；The escape of its volatile solvent can also make traditional excessive glue scavenger that can have service life simultaneously Short problem.Therefore, it is good to develop a kind of removal effect, novel adhesive remover environmental-friendly and with long service life has important section Learn meaning and application value.

Summary of the invention

It is an object of the invention to the defect for overcoming the pollution of excessive glue scavenger in the prior art environment, service life short and not Foot, provides a kind of excessive glue scavenger.Excessive glue scavenger environmental pollution provided by the invention is small, long service life, except glue is quick, high Effect, does not damage optical glass surface precision, especially suitable for the removing of mobile phone camera glass excessive glue, has good answer Use prospect.

Another object of the present invention is to provide the preparation methods of above-mentioned excessive glue scavenger.

Another object of the present invention is to provide above-mentioned excessive glue scavenger in scavenger in removing crown class, flint class optics glass Application in the excessive glue of the materials glass such as glass, sapphire glass.

For achieving the above object, the present invention adopts the following technical scheme:

A kind of excessive glue scavenger, is grouped as by the group of following mass fraction:

The main solvent is one or both of N-Methyl pyrrolidone or tetrahydrofuran；

The cosolvent is one or both of glycol monoethyl ether or propylene glycol monomethyl ether.

The present invention selects the cooperation of the components such as alkaline agent and solvent to realize the removing of excessive glue.The study found that using alkaline agent and The swelling of glue can be achieved in the cooperation of solvent: solvent dissolves excessive glue, then alkaline agent and excessive glue interact so that solvent penetration enter it is excessive The removing of excessive glue is realized so that excessive glue is swollen in the inside of glue.But the cooperation between the type of alkaline agent, alkaline agent and solvent Effect will have a huge impact effect, efficiency and the damage of substrate etc. except glue.If the solvent dissolution selected is too By force, alkaline agent alkalinity is too strong, and alkaline agent reacts rapidly with excessive glue, is conducive to solvent penetration and enters the inside of excessive glue, and then promotes excessive glue Swelling, realizes the fast eliminating of excessive glue, but its that there are reaction speeds is too fast, excessively fierce, cause the glue without removing also molten It is swollen, or even the risk of damage substrate；Dissolution such as solvent is too weak, alkaline agent alkalinity it is too weak, then be unfavorable for solvent penetration into The inside for entering excessive glue can not achieve the preferable swelling and removing of excessive glue.

The present invention has obtained long service life by the screening to alkaline agent and solvent, and by the coordinated of each component, Except glue speed is fast, to the formula that substrate especially optical glass surface precision is not damaged, the principle is as follows: the present invention selects special Fixed main solvent and cosolvent cooperation, it is more appropriate to the dissolution of excessive glue, then matched using organic alkali and organic weak base It closes, and makes it that there is more suitable reaction speed with excessive glue by the dosage of both control, then in surfactant Under cooperation, main solvent penetrates into the inside of excessive glue, so that excessive glue is swollen, and then removes；Through testing, excessive glue removing provided by the invention Agent is reusable, long service life, and rapidly and efficiently except glue, general 5min or so can remove extra excessive glue；In addition, the spy Fixed main solvent and cosolvent be not volatile, and environmental pollution is small.

Preferably, the excessive glue scavenger, is grouped as by the group of following mass fraction:

It is further preferable that the excessive glue scavenger is grouped as by the group of following mass fraction:

Preferably, the organic alkali is one or more of sodium methoxide, potassium methoxide, sodium ethoxide or potassium ethoxide.

It is further preferable that the organic alkali is sodium methoxide.

Preferably, the organic weak base is monoethanolamine, diethanol amine, triethanolamine, triethylamine or hydroxyethyl ethylenediamine One or more.

It is further preferable that the organic weak base is monoethanolamine.

Preferably, the surfactant is fatty alcohol polyoxyethylene ether, nonylphenol polyoxyethylene ether or fatty alcohol polyoxy The phosphatic one or more of vinethene.

Preferably, the main solvent is N-Methyl pyrrolidone.

Preferably, the cosolvent is glycol monoethyl ether.

The preparation method of above-mentioned excessive glue scavenger includes the following steps: for organic alkali to be added in cosolvent and dissolve, then according to Secondary addition main solvent, organic weak base and surfactant stir up to the excessive glue scavenger.

Above-mentioned excessive glue scavenger is in the excessive glue of removing crown class optical glass, flint class optical glass or sapphire glass Using also within the scope of the present invention.

The application method of excessive glue scavenger provided by the invention is as follows: using at normal temperature.By substrate (such as light wait remove glue Learn camera lens) it is immersed in excessive glue adhesive remover, after excessive glue is removed, substrate is transferred in deionized water, cleaning is adhered to light The adhesive remover for learning camera lens surface, is then dried, dry, spare.Excessive glue adhesive remover may continue to for handling next group substrate.

Compared with prior art, the invention has the following beneficial effects:

Excessive glue scavenger provided by the invention is free of volatile organic solvent, and environmental pollution is small, long service life, except glue speed Degree rapidly and efficiently, does not damage optical glass surface precision, especially suitable for the removing of mobile phone camera glass excessive glue, has Good application prospect.
