Description
Technical Field
The invention relates to a manufacturing process of a high-transmittance touch film, and belongs to the technical field of printing processes.
Background
In the field of intelligent control, the combination of a plastic cover plate and a touch function is comprehensively applied to the field of household appliances. The current touch control membrane adopts a screen printing process. Since the ink needs to be protected from oxidation or corrosion after printing. Especially your product in the washing machine and kitchen. The product salt spray test must meet 168H. The conventional approach is to use a single-sided tape over the ink to protect against this experimental requirement.
The common single-sided adhesive tape contains weak acid, and slow corrosion phenomenon can occur after the adhesive tape is contacted with ink for a long time. Secondly, the single-sided tape reduces the transmittance of the entire product. Therefore, the conventional process using single-sided adhesive cannot meet the requirement of products with high transmittance.
Disclosure of Invention
The invention provides a manufacturing process of a high-transmittance touch film, which is used for overcoming the defect that the transmittance of a product is reduced by using a single-sided adhesive in the prior art.
In order to solve the technical problems, the invention provides the following technical scheme:
the invention discloses a manufacturing process of a high-transmittance touch film, which comprises the following steps:
1) after the material is aged, printing transparent conductive ink is used as a key electrode, and 80-degree frictioning is used during printing of the transparent conductive ink, so that the printing uniformity of the ink is ensured;
2) printing high-transmittance insulating ink twice, wherein the thickness of the printed film is controlled to be 8-12 microns;
3) the double-sided adhesive tape is changed into OCA optical adhesive tape without adhesive marks.
Furthermore, the glue scraping frequency is two, and the phenomenon of sand hole or blockage can be prevented.
Furthermore, the thickness of the printing film ensures the quality, plays a role of a protective layer for a later destructive test, replaces the function of single-sided adhesive, and improves the transmittance of the product.
The invention has the following beneficial effects: according to the invention, the high-transmittance insulating ink is printed on the touch film, a single-sided tape laminating process is omitted, a set of working procedures and raw materials are saved, the cost is reduced through comprehensive evaluation, the use of PET single-sided adhesive high-molecular polymers is reduced, the environment is protected, manual laminating is omitted, and the production efficiency is improved.
Detailed Description
The preferred embodiments described herein are merely illustrative and explanatory of the invention and are not restrictive thereof.
Example 1
A manufacturing process of a high-transmittance touch film comprises the following steps:
1) after the material is aged, printing transparent conductive ink is used as a key electrode, and 80-degree frictioning is used during printing of the transparent conductive ink, so that the printing uniformity of the ink is ensured;
2) printing high-transmittance insulating ink twice, wherein the thickness of the printed film is controlled to be 8-12 microns;
3) the double-sided adhesive tape is changed into OCA optical adhesive tape without adhesive marks.
The scraping times are two, and the phenomenon of sand hole or blockage can be prevented.
The thickness of the printing film ensures the quality, plays a role of a protective layer for a later destructive test, replaces the function of single-sided adhesive, and improves the transmittance of the product.
For a conventional process of a product with high requirement on transmittance, the area needs to be left out when printing insulation, and the reliability test requirement of the product can be met after a single-sided adhesive tape is attached. Particularly in the salt spray experiment, if silver paste and electrode materials are not protected, the function is lost after the salt spray time. The high-transmittance insulating ink manufactured and used by the novel process has no influence on transmittance, other ink layers can be well protected from being damaged, and all reliability test requirements can be met. Secondly, in order to prevent bad phenomena such as sand holes and the like in the screen printing process. High-transparency insulation needs to be printed twice, the thickness of a printed film needs to be controlled to be 6-8u, two different screen printing plates are used, the double-sided adhesive is changed into OCA optical adhesive, the permeability of a product is improved, the window transmittance of the product manufactured by the process is attractive after the touch film and the plastic cover plate are combined, and no adhesive mark or air bubble exists.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
