Problems solved by technology

[0004] As a plastic transparent substrate, PC (polycarbonate), PET, PE or PMMA is used, but in general, plastic transparent substrates have low surface hardness, reduced durability, fingerprint resistance, scratch resistance, Problems with low stain resistance, heat resistance, transmittance and haze characteristics
[0005] In order to solve the above-mentioned problems, Korean Patent Application No. 2009-7009932 discloses a polycarbonate laminate having an improved surface hardness by coating polycarbonate with acrylic resin, but the actual situation is that the improved surface hardness is pencil hardness 4H below and still not enough
[0006] In addition, for the case of combining with a touch function such as a smartphone, Protect M Co., Ltd. tries to form a hard coat-self-healing layer-shock diffusion layer-self-cleaning layer-fingerprint prevention Various layers are used as a protective film for mobile phones to improve the surface characteristics of transparent substrates, but there are problems that the process is too complicated and productivity is reduced

Embodiment 1

[0182] [Example 1] Production of Coating Composition Containing Copolymers 1 and 9

[0183] Regarding the synthesis procedure, successive hydrolysis and condensation were performed step by step as follows.

Embodiment 1-a

[0184] [Example 1-a] Catalyst Production

[0185] In order to adjust the basicity, a 10% by weight potassium hydroxide (KOH) aqueous solution was mixed with a 25% by weight tetramethylammonium hydroxide (TMAH) aqueous solution to prepare a catalyst 1a.

Embodiment 1-b

[0186] [Example 1-b] Synthesis of linear silsesquioxane structure

[0187] In a drying flask equipped with a condenser tube and a stirrer, 1 weight part of the catalyst produced in 5 parts by weight of distilled water, 15 parts by weight of tetrahydrofuran, and 1 part by weight of the catalyst produced in the above-mentioned embodiment 1-a was added dropwise, and after stirring at normal temperature for 1 hour, 2-( 20 parts by weight of 3,4-epoxycyclohexyl)ethyltrimethoxysilane, and 15 parts by weight of tetrahydrofuran were added dropwise again, followed by further stirring for 5 hours. Take the mixed solution under stirring, remove the catalyst and impurities by washing twice, and filter it. It can be confirmed by IR analysis that the SI-OH functional group generated at the end group (3200cm -1 ), as a result of measuring the molecular weight, it was confirmed that silsesquioxane having a linear structure such as the chemical formula 4 structure had a molecular weight of 8,000...

Abstract

The present invention relates to a transparent substrate having reinforced surfaces and a method for manufacturing same, and more specifically, to a transparent substrate having reinforced surfaces and a method for manufacturing same, which is capable of significantly improving surface hardness by treating the surfaces with a silsesquioxane complex polymer including, in a single polymer, a silsesquioxane ladder chain and a cage-type silsesquioxane which have a specific structure, and which has improved fingerprint resistance, scratch resistance, pollution resistance, heat resistance, light transmission, and haze characteristics.

Description

technical field [0001] The present invention relates to a surface-enhanced transparent substrate and a manufacturing method thereof. A surface-enhanced transparent substrate having improved surface hardness, fingerprint resistance, scratch resistance, stain resistance, heat resistance, transmittance, and haze characteristics by being treated, and a method for manufacturing the same. Background technique [0002] Transparent substrates are used in various applications. In particular, it is used in various fields of electronic products including smartphones, tablet computers, notebook computers, all-in-one computers (AIO (All-In-One) PC), LCD monitors, TVs, advertising boards, touch panels, etc. The window is covered with a substrate or a protective film, or a transparent substrate is used as a protective sheet for protecting the inside. [0003] A representative example of a transparent substrate is glass, but transparent substrates made of plastics are widely used because ...
