Embodiment Construction

[0019] The present invention will be described in further detail below.

[0020] An anti-fingerprint film, comprising a plastic substrate 1 and a perfluoropolyether or organic silicon polymer film 2 deposited on the surface of the plastic substrate, the substrate 1 is a PET sheet, a PC sheet or a PMMA sheet, and the The perfluoropolyether polymer is ethylene or tetrafluoroethylene, and the thickness of the film 2 is 5-30nm.

[0021] A preparation method for an anti-fingerprint film, comprising the steps of:

[0022] First, select a plastic sheet as the substrate, and use isopropanol as a solvent to ultrasonically clean the substrate for 10 minutes.

[0023] Then put the base material into the vacuum evaporation coating machine and carry out high vacuum pumping until the vacuum degree is lower than 100Pa.

[0024] Afterwards, use an infrared heating substrate baking device to bake the substrate, set the temperature at 50-60°C, in order to shorten the pumping time and complete...

Abstract

The invention discloses an anti-fingerprint film, comprising a plastic cement base material and perfluoropolyether or an organosilicon polymer film, wherein the perfluoropolyether or the organosilicon polymer film is deposited on the surface of the plastic cement base material; the thickness of the film is 5-30nm; and the invention also discloses a preparation method of the anti-fingerprint film. The surface of the base material of the invention is deposited with the perfluoropolyether or the organosilicon polymer film; the contact angle of water and oil stain on the film is increased, thus being difficult to be paved smoothly; the anti-fingerprint film has the advantages of hydrophobicity, oleophobicity, low sliding angle, wear resistance and ageing resistance; the anti-fingerprint performance of the surface of a product is improved; the phenomenon of easy-sticking with fingerprint smudginess of the traditional product is changed; and the attractive appearance of the product can be guaranteed all the time in the use process.

Description

technical field [0001] The invention relates to an antifouling film, in particular to an antifingerprint film and a preparation method thereof. Background technique [0002] At present, many product surfaces that are in frequent contact with the skin are easily stained with fingerprints and other dirt during use, and such dirt is difficult to wipe off, so that the bright appearance of the product during use is greatly reduced. In order to make the appearance surface of these products have excellent physical properties, organic matter is generally used for treatment, so that oil stains, fingerprints, etc. are easier to spread on the surface. Contents of the invention [0003] The purpose of the present invention is to provide an anti-fingerprint film that can keep the appearance of the product clean and make fingerprints and other dirt easy to wipe clean. [0004] The technical solution adopted by the present invention to solve the technical problem is: an anti-fingerprint...
