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 coating method and a coated PET, which belong to the technical field of coating. The method includes: step S01, sputtering Ti on the surface of the PET substrate; step S02, coating the PET substrate on which the Ti layer is sputtered. The coated PET is prepared based on the above method. The present invention coats the basic surface of the PET flakes, adopts a specific film layer design, makes it bonded precisely with the PET surface, and achieves light absorption with an average reflectance of less than 0.15% in the 400nm-700nm spectrum band.

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...
