Abstract

The invention relates to an aqueous transfer membrane demolding agent as well as a preparation method and application thereof. The aqueous transfer membrane demolding agent consists of the following components in parts by mass: 10-25% of an inorganic strong base, 10-20% of an organic weak base, 8-20% of a main solvent, 5-20% of a cosolvent, 2-5% of a surfactant, 1-15% of a chelating agent and thebalance of water. The aqueous transfer membrane demolding agent provided by the invention has the properties of rapidness and high efficiency, can be repeatedly used for a long time, has no influenceupon a substrate surface, particularly the precision of a sapphire cover plate, and has good application prospects in the precise processing industry.

Description

technical field [0001] The invention belongs to the technical field of chemical paint remover, and in particular relates to a water-based transfer film remover and its preparation method and application. Background technique [0002] Fingerprint recognition is the mainstream personal identification method for modern smartphones. Sapphire glass has the advantages of high hardness and corrosion resistance, and is widely used as the fingerprint identification cover of Apple mobile phones and some domestic high-end models. However, during the thermal transfer process, sapphire glass is prone to unqualified phenomena such as bumps, pits, pinholes, and unevenness, and some products cannot enter the next step. Due to the high processing cost of sapphire glass, if the thermal transfer film on the surface of unqualified products cannot be removed and reused, it will cause a large waste of resources. [0003] At present, the conventional transfer film release agent is mainly compose...
