Problems solved by technology

However, after the reflow test of the existing ink layer and ink hard coating, the color difference value changes are greater than 1, which cannot pass the anti-reflow test
[0005] In addition, the ink layer and the ink hard coat layer need to be produced in two separate coating processes, which not only increases the complexity of the fingerprint identification device process, but also leads to increased process costs and decreased production capacity.

Embodiment Construction

[0042] In one embodiment of the present invention, the resin hardener of the coating film is suitable for the production of the ink coating film of the fingerprint reader. In some examples, the resin hardener of the coating film includes silicone resin, silicone coupling agent resin and organic solvent. For example, based on the total weight percentage of the resin hardener being 100wt%, the content of the silicone resin is 0.1wt% to 99.8wt%, the content of the silicone coupling agent resin is 0.1wt% to 99.8wt%, and the content of the organic solvent The content is 0.1wt% to 99.8wt%.

[0043] The silicone resin can be, for example, silicone modified resin or silicone oil. Silicone resin is a polymer between organic and inorganic. In some instances, silicone resins have the formula [-R 2 SiO-] n , wherein R is an alkane, acrylic, epoxy or aromatic group. The material of silicone resin is composed of inorganic silicon-oxygen bond skeleton (...-Si-O-Si-O-Si-O-...) and branch...

Abstract

The invention relates to a resin hardening agent of a coating film, an ink coating film composition and an ink coating film manufacturing method. According to the present invention, the resin hardening agent of the coating film comprises 0.1-99.8 wt% of a silicon oxygen resin, 0.1-99.8 wt% of a silicon oxygen coupling agent resin, and 0.1-99.8 wt% of an organic solvent; with the resin hardening agent, the coating film can have advantages of high hardness, wear resistance and temperature resistance, and the chromatic aberration value of the coating film after the reflow soldering is less than 1; the dielectric constant of the ink coating film can be adjusted, such that the application in the capacitive fingerprint identification device is easily achieved; and the ink coating film production can be completed only requiring the single-channel film plating process, such that the ink coating film production process is simple and easy to perform, the production cost can be reduced, and the production capacity can be improved.

Description

technical field [0001] The invention relates to a surface coating technology, and in particular to a resin hardener for a coating, an ink coating composition and a method for manufacturing an ink coating. Background technique [0002] With the increasing popularity of portable electronic products, it has become one of the development trends to install fingerprint recognition devices on portable electronic products. At present, a common fingerprint recognition device is a capacitive fingerprint reader. A capacitive fingerprint reader usually includes a fingerprint reader and an ink layer, wherein the ink layer is coated on the fingerprint reader. However, most of the existing ink layers cannot meet the anti-wear requirements. [0003] In order to meet the anti-wear requirements, most of the ink layers are coated with a hard coating of ink at present. The ink hard coat can fix the ink layer and protect the ink layer and fingerprint reader. The ink hard coat is generally ba...
