Blue film removing agent and demolding method of mobile phone glass workpiece

Abstract

The invention discloses a blue film removing agent, which comprises the following components in percentage by mass: 2-15% of a penetrating agent, 10%-20% of an auxiliary agent; 1%-6% of a corrosion inhibitor; and balance of water. According to the invention, the penetrating agent, the auxiliary agent, the corrosion inhibitor and the water are reasonably compounded, all the components are reasonably screened, the components are simple, the preparation is easy, the method is suitable for industrial production, and the penetrating agent is used for weakening the binding force between a blue film and the surface of glass and has excellent removal capability on the blue film; the auxiliary agent is used for destroying a net structure of organic resin in the blue film, so that the blue film is decomposed into small sheet structures, and hanging is avoided; and the corrosion inhibitor has a corrosion inhibition effect on a glass substrate, so that the surface of the demoulded glass is bright, and adverse effects such as corrosion and scratch are reduced. The invention further provides a demolding method of the mobile phone glass workpiece.

Description

technical field

[0001] The invention relates to the technical field of removers, in particular to a blue film remover used for removing blue films of mobile phone glass shards and a method for demoulding mobile phone glass workpieces. Background technique

[0002] The existing mobile phone glass processing technology, from slitting, profiling, CNC, to polishing, etc., is very easy to cause a certain degree of scratches to the glass in the machine or other operations. These scratched glasses often need to be ground and eliminated in the subsequent process by using a flat grinding process. For severely scratched glass, if it cannot be eliminated by flat grinding, the product can only be scrapped. Therefore, the protection of mobile phone glass during processing is particularly important. At present, the best protection method is to use printing protection ink, that is, blue film, which has a good protection effect and is suitable for mass production.

Examples

Embodiment 1

[0028] A blue film remover comprises the following components in mass fraction: 5% of fatty alcohol polyoxyethylene ether, 5% of ethylenediamine, 10% of sodium carbonate, 2% of sodium borate, and 78% of water.

[0029] Add each component sequentially and mix to form the blue film remover.

[0030] Fully immerse the mobile phone glass covered with the blue film in the 30% dilution of the above remover, soak for 60 seconds at 70°C~75°C, then take out the glass and rinse it with pure water at 30°C~40°C, and rinse it with pure water at 80°C~ Dry at 100°C to obtain a clean mobile phone glass.

Embodiment 2

[0032] A blue film remover comprises the following components in mass fraction: fatty alcohol polyoxyethylene ether sodium sulfate 2%, lauryl amidopropyl betaine 6%, methylamine 10%, tert-butylamine 3%, siloxane 5%, Water 74%.

[0033] Add each component sequentially and mix to form the blue film remover.

[0034] Fully immerse the mobile phone glass covered with the blue film in the 40% dilution of the above remover, soak for 40 seconds at 70°C~75°C, then take out the glass and rinse it with pure water at 30°C~40°C, and rinse it with pure water at 80°C~ Dry at 100°C to obtain a clean mobile phone glass.

Embodiment 3

[0036] A blue film removing agent comprises the following components in mass fraction: 3% polyoxyethylene monooleate of sorbitan, 5% urea, 7% cyclohexylamine, 3% sodium silicate and 82% water.

[0037] Add each component sequentially and mix to form the blue film remover.

[0038] Fully immerse the mobile phone glass covered with the blue film in the 32% dilution of the above remover, soak for 70 seconds at 70°C~75°C, then take out the glass and rinse it with pure water at 30°C~40°C, and rinse it with pure water at 80°C~ Dry at 100°C to obtain a clean mobile phone glass.
