AI Technical Summary

Problems solved by technology

At present, the ink on the market is difficult to achieve a balance between protection and deinking. In mass production, the rejection rate is high and the deinking speed is slow, which will consume a lot of production time and manpower, and reduce production capacity and benefits.

Embodiment 1

[0043] In this embodiment, a kind of ink is provided, and described ink comprises the following components by weight:

[0044]

[0045]

[0046] The o-cresol novolac epoxy acrylate prepolymer, polyurethane resin, polyurethane acrylate prepolymer, epoxy resin, and solvent are weighed and fed. After stirring evenly, add 510 polymerization inhibitor, DETX, IRGACURE 369, titanium dioxide, barium sulfate, talcum powder, melamine, use a three-roller grinder to grind to a fineness of less than 10 microns, and then add leveling agent and anti-corrosion agent while stirring. After the oil agent and matting powder are uniformly dispersed, the ink can be obtained.

Embodiment 2

[0048] In this embodiment, a kind of ink is provided, and described ink comprises the following components by weight:

Abstract

The invention provides ink, a preparation method and application thereof. The ink comprises the following components in parts by weight: 40-60 parts of an o-cresol epoxy acrylic resin prepolymer, 10-20 parts of a polyurethane acrylate prepolymer, 4-8 parts of a polyurethane resin, 5-10 parts of an epoxy resin, 0.01-0.1 part of a polymerization inhibitor, 3-6 parts of a photopolymerization initiator, 1-2 parts of melamine and 10-15 parts of a solvent. According to the invention, the ink is high in wetting capacity, shrinkage cavities cannot be generated in a dirty base material, strong-corrosion-resistant acid soaking can be resisted, the deinking time is short, no residue is left, and deinking is easy to form fragments and is not easy to hang.

Description

technical field [0001] The invention belongs to the technical field of cover glass, and relates to an ink and a preparation method and application thereof, in particular to a protective ink for 3D cover glass and a preparation method thereof. Background technique [0002] The current cover glass processing technology can produce different graphics requirements through etching. Use hydrogen fluoride, nitric acid or frosting solution on one side of the glass to corrode a part of the glass, and then carve graphics with different textures, which can be patterned or frosted. and other visual effects. However, it is necessary to cover the non-etched surface or the part that does not need to be etched with a protective film to avoid accidental etching and damage to the appearance. The most commonly used method is the way of printing protective ink, which is suitable for mass production. At present, the ink on the market is difficult to achieve a balance between protection and dei...
