Embodiment 1

[0075] A preparation method of an anti-fingerprint agent, comprising:

[0076] Step 1: In a 5-liter high-pressure reactor equipped with a mechanical stirrer, under a nitrogen atmosphere, add 2000 mL of acetonitrile and 3310 g of compound B1 while stirring 83g of sodium dithionite and 21g of sodium bicarbonate were replaced with ethylene three times, then ethylene was introduced, heated to a temperature of 50°C, and reacted for 10 hours. 19FNMR followed the reaction. After the reaction, most of the solvent was evaporated under reduced pressure, and 2000 mL of water was added to the reaction system at a lower temperature, and the filtrate was obtained by filtration. The filtrate was extracted three times with 2000 mL of ethyl acetate, and the organic phase was extracted with 2000 mL of saturated sodium sulfite aqueous solution and 2000 mL of water respectively. Each wash once, after distilling off the extraction solvent, the water pump vacuum distillation obtains 1366g compound...

Embodiment 2

[0084] A preparation method of an anti-fingerprint agent, comprising:

[0085] Step 1: In a 5-liter high-pressure reactor equipped with a mechanical stirrer, under a nitrogen atmosphere, add 2500 mL of ethanol and 1235 g of compound B2 while stirring and 36g of benzoyl peroxide (BPO), replaced by ethylene three times, then passed through ethylene, heated to a temperature of 100°C, and reacted for 5h. After the reaction was completed, the filtrate was cooled and filtered to obtain the solvent. First, the solvent was removed by distillation under reduced pressure, and 1500 mL of dichloromethane was added. The organic phase was washed once with 2000 mL of saturated sodium sulfite aqueous solution, and then twice with 2000 mL of tap water. After the solvent was removed by distillation under reduced pressure, 1016 g of compound C2 was obtained. , whose structural formula is:

[0086] Step 2: 2000mL of ethylene glycol, 98.6g of magnesium chips, 1.0g of elemental iodine, heat and...

Embodiment 3

[0093] A preparation method of an anti-fingerprint agent, comprising:

[0094] Step 1: In a 5-liter high-pressure reactor equipped with a mechanical stirrer, under a nitrogen atmosphere, add 2000 mL of chloroform and 1650 g of compound B3 while stirring and 61g of benzoyl peroxide, replaced by ethylene three times, then passed into ethylene, heated to a temperature of 150°C, and reacted for 1h, using 19 F NMR followed the reaction. After the reaction, most of the solvent was evaporated under reduced pressure, and 2000mL of water was added to the reaction system at a lower temperature, and the filtrate was obtained by filtration. Each wash once, after distilling off the extraction solvent, the oil pump decompression distillation obtains 1450g compound C3, and its structural formula is:

[0095] Step 2: Fully stir and dissolve 2000mL ethylene glycol, 1500mL isopropyl ether and 545g potassium tert-butoxide, add toluene until there is no water in the system, then cool down to ...

Abstract

The invention provides an anti-fingerprint agent, comprising compound A and an organic solvent, the structural formula of compound A is: wherein R is methyl, ethyl, propyl or isopropyl, n is a positive integer of 3-20, Compound A has low surface energy and high stability, and is environmentally friendly. The anti-fingerprint agent can be coated on the surface of display devices and optical components to improve the surface's oleophobicity, hydrophobicity and anti-fingerprint effect, while improving the performance of display devices and optical components. The durability of the anti-fingerprint effect on the surface of the optical component, and the invention also provides a preparation method of the anti-fingerprint agent.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to an anti-fingerprint agent and its preparation method and application. Background technique [0002] In recent years, the touch panels of electronic products are easily contaminated by fingerprints, skin oils, sweat and cosmetics when used in a bare state. Therefore, in order to improve the appearance and recognition, there are more and more requirements for the technology that fingerprints are not easy to adhere to the display surface or the technology for easy removal of dirt. The surface is not easy to cause damage and has good wear resistance, so it is often necessary to spray an anti-fingerprint agent on the surface of the touch screen. [0003] The main component of the commonly used anti-fingerprint agent is a perfluoropolymer compound with a special functional group, which has a series of physical and chemical properties such as excellent thermal stability, hydr...
