Embodiment Construction

[0022] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0023] Such as figure 1 , a PET coating method of the present invention, comprising:

[0024] Step S01, sputtering Ti on the surface of the PET substrate;

[0025] Step S02, coating the PET substrate on which the Ti layer is sputtered.

[0026] Step S01 specifically includes: the vacuum sputtering coating machine vacuumizes the cavity, for example, to a range of 4E-4 to 2.0E-3Pa. Subsequently, Ti was sputtered on the surface of the PET substrate. Preferably, the sputtered Ti layer has a thickness of 20-200 nm.

[0027] Afterwards, the film layer is plated on the PET substrate through the Ti layer. The Ti layer acts as a bonding layer between the film layer and the substrate. Due to the good coverage of Ti, less voids...

Abstract

The invention discloses a PET film coating method and film coated PET and belongs to the technical field of film coating. The PET film coating method comprises the following steps: S01, sputtering Tion the surface of a PET base plate; and S02, carrying out film coating on the PET base plate sputtered with the Ti coating. The film coated PET is prepared through the PET film coating method. According to the PET film coating method, film coating is carried out on the basic surface of a PET sheet; specific coating design is adopted to enable the film to precisely bond with the PET surface, and the light absorption function that the average reflectivity is less than 0.15% is realized at the spectral bands of 400-700 nm.

Description

technical field [0001] The invention belongs to the technical field of coating, and in particular relates to a PET coating method and a coated PET. Background technique [0002] Anti-reflective coatings similar to low reflectivity are generally used on substrates such as glass, which are relatively insufficient in brittleness and ductility, and the most important thing is that they cannot achieve light absorption. The existing coating technology coats the surface of PET, and the PET is seriously wrinkled, the film layer is uneven, and the spectrum does not meet the requirements. [0003] Invention patent application CN201510835077.5 discloses a coating preparation process for electronic equipment casings, and specifically discloses that the process includes the following steps: ion bombardment step: placing a transparent PET sheet that has undergone UV transfer printing on one side in a vacuum coating chamber, Perform ion bombardment on the surface of the PET sheet; coating...
