Problems solved by technology

In the case of inorganic coating by vacuum deposition, there are limitations in the substrates that can be coated due to the high ignition point (coating materials are temperature sensitive - tempered glass, plastic, etc.), and due to inorganic or metal coating, the material Discoloration of the surface itself, resulting in reduced optical performance
[0006] Korean Patent Application No. 10-2002-0066286 (Applicant: WIDE ENTECH Co., Ltd. Vacuum Deposition System Using Nanotechnology with Antibacterial Effect) relates to a technology for developing and applying a vacuum deposition system using nanotechnology with antibacterial effect, In this application, it is attempted to use plant materials (Erythrina, elm, plum, etc.) to achieve antibacterial effect, but there are problems of insufficient antibacterial function, difficulty in maintaining sustainability, and functionalities such as waterproof / oil repellency and anti-slip property cannot be realized The problem
[0007] U.S. Publication No. US2011 / 0025933 (applicant: VIZIO INC, TV with antimicrobial coating, TELEVISION WITH ANTIMICROBIAL COATING) discloses a coating agent containing an antimicrobial agent on the outer surface of the TV to inhibit the growth of microorganisms However, this application also has the problem of not being able to realize functions such as waterproof / oil repellency and slip resistance.
[0008] Japanese Patent Application No. 2007-322624 (Applicant: ZNO LAB, Antibacterial material and method for producing the same) discloses an antibacterial material and method for producing the same, which is characterized in that, by vacuum deposition , sputtering and other methods to form a zinc oxide film on a glass substrate or plastic that can be used as a touch panel or a mobile phone surface. However, this application also has the problem of not being able to achieve functions such as waterproof / oil repellency and skid resistance, and There is a problem of optical performance degradation due to metal thin films

preparation example Construction

[0036] According to the second aspect of the present invention, there is provided a method for preparing a dry antibacterial coating agent for vacuum deposition, including the following steps: a) preparing a mixture containing a fluorine-based polymer, a functional organic or inorganic silane compound, and an antibacterial substance; And b) subjecting the mixture to a polycondensation reaction.

[0037] According to a third aspect of the present invention, there is provided a method for preparing a dry antibacterial coating agent for vacuum deposition, including the following steps: i) preparing a mixture containing a fluorine-based polymer and a functional organic or inorganic silane compound; ii) combining The mixture undergoes a polycondensation reaction; and iii) the antibacterial substance is poured into and dispersed into the product of the polycondensation reaction to mix.

[0038] The method and equipment used to prepare the mixture are not particularly limited, and convent...

Embodiment 1

[0050] 15 g of chitosan as an antibacterial substance was added to 50 g of perfluoropolyether as a fluorine-based polymer. Among them, 50g of aminopropyltriethoxysilane as a functional organic or inorganic silane compound was added, and the polycondensation reaction was carried out under an inert argon atmosphere at a temperature of about 150°C, and then the reaction product was stabilized at room temperature for 24 hours. Thus, a dry antibacterial coating agent is prepared.

Embodiment 2

[0052] A dry antibacterial coating agent was prepared in the same manner as in Example 1, except that 8 g of paeoniflorol as an antibacterial substance was further added.

Abstract

The present invention relates to a functional coating agent having antimicrobial activity and water-repellency / oil-repellency at the same time, a method for preparing the same, and a coating method using the same. Specifically, the present invention relates to a method for preparing a coating agent which provides antimicrobial activity to a water-repellent / oil-repellent nanocoating in order for smart devices, etc., such as touch-type displays, to be used hygienically, and a coating method using vacuum deposition equipment.

Description

Technical field [0001] The present invention relates to a functional coating agent that realizes antibacterial properties and water / oil repellency at the same time, a preparation method of the coating agent, and a coating method using the coating agent, in particular, to a method for touch The use of smart devices such as type displays is hygienic, and the preparation of coating agents that impart antibacterial properties for waterproof / oil-repellent nano-coating and coating methods using vacuum deposition equipment. Background technique [0002] With the rapid increase in the use of smart devices with touch-sensitive displays (smartphones, tablets, smart watches, etc.), the severity of health problems has increased, and the attention to antibacterial has also increased. However, the anti-fingerprint coating currently used does not have an antibacterial function. Therefore, there is an urgent need to develop a technology that can impart an antibacterial function to a touch screen...
