Technical field

The invention belongs to chemical coating scavenger technical fields, and in particular to a kind of aqueous transfer printing film remover and its preparation Methods and applications.

Background technique

Fingerprint recognition is mainstream individual's identification method of modern smart phone.Sapphire glass has hardness high, corrosion-resistant The advantages that, it is widely used and makees the fingerprint recognition cover board of iPhone and the high-end type of partial domestic.But it is processed in thermal transfer Sapphire glass is easy to produce unqualified phenomenon, the portioned product such as salient point, concave point, pin hole, uneven and not can enter next in journey Walk process.It is again sharp if substandard product surface heat-transferring film cannot be removed since the processing cost of sapphire glass is high With will cause the biggish wasting of resources.

The remover of conventional transfer film is mainly living by macromolecule degradation agent and strength mixed solvent and surface at present Property the composition such as agent.Its typically cost is high, use process operation is relative complex and easily causes wood destruction.Based on sapphire glass Glass itself has high value, and its is with a wide range of applications, therefore develops with inexpensive, easy to operate and removal rate High remover is for promoting the processing of sapphire glass thermal transfer to have great importance.Aqueous transfer printing film remover has environment Security performance, while its corrosion that not will cause substrate, and there is operability simply, therefore develop with efficient demoulding ability And aqueous remover at low cost, have great importance to the transfer film development of sapphire glass.

Summary of the invention

It is an object of the invention to overcome in the prior art, transfer film is at high cost, use process operation is relative complex simultaneously And the features such as easily causing wood destruction.The present invention provides a kind of aqueous transfer printing film remover.Aqueous transfer printing film provided by the invention Remover has demoulding quickly, efficiently (general 5min or so can remove transfer mold)；It is reusable, long service life；It is right It substrate surface the advantages that especially sapphire cover board precision does not influence, has a good application prospect in practical applications.

Another object of the present invention is to provide the preparation methods of above-mentioned aqueous transfer printing film remover.

Another object of the present invention is to provide above-mentioned aqueous transfer printing film removers in removing sapphire cover board or optics glass The application in aqueous transfer printing film on glass.
