Problems solved by technology

However, the use of multi-layer coating will increase the thickness, increase the complexity of the process, reduce the yield of the process, and lead to waste of cost
[0007] This shows that above-mentioned existing cured resin coating obviously still has inconvenience and defect in structure and use, and demands urgently further improving
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve

Embodiment 1

[0036] Please refer to FIG. 1 , which shows a schematic cross-sectional structure diagram of a cured resin coating according to a preferred embodiment of the present invention. In FIG. 1 , the resin coating 120 is located on the substrate 110 , and micron particles 130 with higher hardness are added in the resin coating 120 to increase the hardness of the resin coating 120 .

[0037] When the ultraviolet light irradiates the resin coating 120 to harden it, the resin coating 120 will undergo a cross-linking and hardening reaction. Since the cross-linking hardening reaction is fast, and the time is about 1-2 seconds, the resin coating 120 will cause stress concentration due to instantaneous shrinkage, and the resin coating 120 will warp. However, after micron particles 130 are added to the resin coating 120, the micron particles 130 can compensate for the shrinkage of the resin coating 120 during the cross-linking hardening process, reduce the warpage of the resin coating 120, a...

Embodiment 2

[0044] Please refer to FIG. 2 , which shows a schematic cross-sectional structure diagram of a cured resin coating according to another preferred embodiment of the present invention. In FIG. 2, the resin coating 220 is located on the base material 210. In addition to adding the micron particles 230 with higher hardness in the resin coating 220, nanoparticles 240 with higher hardness are added to further increase the hardness. The hardness of the resin coating 220 . The above-mentioned nanoparticles 240 have a particle size range of 5-100 nm, and their materials are preferably inorganic materials, such as silicon oxide, titanium oxide, or aluminum oxide. The materials of the base material 210 , the resin coating 220 and the micron particles 230 are the same as those described in the first embodiment, so they are not repeated here.

[0045] In this embodiment, the micro-particles 230 and the nanoparticles 240 are uniformly distributed in the resin coating 220 . If micron parti...

Abstract

A hardening resin coating consists of resin coating on substrate and complex micro-grain which is dispersed into the resin coating, grain size is 1-20 micron and hard micro-grain is added into resin coating. It can eliminate warping.

Description

technical field [0001] The present invention relates to a hardened coating, and more particularly to a hardened resin coating which can be used in displays. Background technique [0002] Judging from the current development trend, the development of displays is becoming more and more diversified, such as liquid crystal displays, plasma displays, cathode ray tube (CRT) displays, outdoor displays or personal digital assistant (PDA) displays. In order to protect the panel of the display, it is therefore necessary to use a hardened coating with excellent anti-friction properties and high hardness. [0003] The conventional hardening coating is generally formed by coating a thermosetting resin material or an ultraviolet light curing resin material on a transparent substrate. Then, the resin is hardened by cross-linking reaction by heating or irradiating with ultraviolet light, so as to form a hardened resin coating, that is, the aforementioned hardened coating. However, during ...
