Problems solved by technology

[0006] The main purpose of the present invention is to provide a surface coating with both hydrophobic and oleophobic effects. When the surface coating is coated on the surface of a traditional touch panel, it can overcome the fact that the traditional touch panel is prone to residual pollutants during operation. In addition, it can also solve the problem that traditional touch panels are prone to glare under strong light.

Embodiment 1

[0035] The manufacturing process of a preferred embodiment of the present invention: first, this surface coating is directly coated on an outer cover plate, and the material of this outer cover plate is PMMA; Or earlier this surface coating is with alcohols, ketones, ether Dilute organic solvents such as benzene or benzene, wherein the alcohol organic solvent can be isopropanol (Isopropanol) or ethanol (Ethanol), and the degree of dilution can be 1000 times, that is, the concentration of the surface coating is controlled to 0.1% by volume percent concentration. Dilution is to mix the surface coating with the organic solvent and uniformly stir the mixed solution. Stirring can be done by means such as mechanical blade stirring, stirring bar rotation, up and down vibration or roller rolling. When the mixed solution reaches stable high uniformity and high dispersion, the mixed solution is then applied to the outer cover, and the coating method can be spray coating (Spray coating),...

Embodiment 2

[0037] The surface test is carried out on the outer cover plate coated with the surface coating with both hydrophobicity and oleophobicity of the present invention. The surface test includes surface energy test, water droplet size test, oil droplet size test and fingerprint press test of glossiness. The result looks like this:

[0038] (1) Surface energy test:

[0039] Surface energy test is carried out with Dyne Test Pen (also known as corona test pen), and the surface energy of the outer cover plate coated with the hydrophobic and oleophobic surface coating of the present invention is less than 30dynes / cm ; And the surface energy of a general glass substrate is 47dynes / cm, so the outer cover plate coated with the surface coating of the present invention has a lower surface energy.

[0040] (2) Droplet size test:

[0041] Prepare 20 pieces of outer cover plates (experimental group) and uncoated outer cover plates (control group) that are 5cm × 5cm and coated with the surfac...

Embodiment 3

[0057] Carry out the weather resistance test of the glossiness to the outer cover plate that is coated with the surface coating of hydrophobicity and oleophobicity of the present invention concurrently, weather resistance test comprises high temperature test (high temperature test), low temperature test (low temperature test), high humidity test (high temperature test). humidity test) and thermal shock test, the results are as follows:

[0058] (1) High temperature test:

[0059] Prepare 20 outer cover plates with a size of 5cm×5cm and coated with the surface coating with both hydrophobicity and oleophobicity of the present invention. The outer cover plates are first tested with a gloss meter, and then tested at 80°C After 200 hours of high-temperature treatment in the environment, and then tested with a gloss meter, the results of the gloss (GU) are listed as follows:

Abstract

The invention relates to a surface coating with both hydrophobicity and oleophobic property and a touch control panel coated by the surface coating. The surface coating comprises nano particles of chemical structures shown as formula (I): R1 may be halogen, hydrogen, alkyl, alkoxy, hydroxyl, alkenyl, alkyne, acyl, acryl, carboxyl, alkoxycarbonyl or aromatic oxycarbonyl, R2 may be a fluorine-containing group. The touch control panel comprises a conductive layer or an outer cover plate coated by the surface coating with both hydrophobicity and oleophobic property. When the surface coating is coated on the outer cover plate or the conductive layer of the touch control panel, the touch control panel is easy to clean, can resist greasy dirt, can prevent fingerprint generation, and has excellent anti-glare properties by virtue of the excellent hydrophobicity and oleophobic property of the surface coating.

Description

technical field [0001] The invention relates to a surface coating and a touch panel coated with the surface coating, in particular to a hydrophobic and oleophobic surface coating and a touch panel using the surface coating. Background technique [0002] Compared with traditional input devices, touch panels allow users to directly use their fingers to perform various commands on electronic devices in an intuitive manner, thereby providing excellent human-computer interaction performance, and at the same time have fast operation speed and high precision. and small size advantages. Therefore, touch panels have gradually replaced input devices such as keyboards and mice, and are widely used in consumer electronic products such as personal computers, mobile communication devices, portable media players or e-books. Currently, most touch panels on the market use two types of sensing technologies: resistive and capacitive. [0003] In the case of a resistive touch panel, its struc...
