Embodiment

[0240] Hereinafter, the present invention will be specifically described by examples, but the present invention is not limited by these examples. In addition, Examples 1 to 3, 5 to 12, 14 to 19 are examples, Examples 4, 13 are comparative examples.

[0241] Compounds used in the preparation of each membrane formation composition in each membrane formation, etc. are exemplified below.

[0242]

[0243] · Sili-based ultraviolet absorber solution: Add 2, 2 ', 4,4'-tetrahydroxybenzophenone (BASF system) 49.2 g, 3-cyclopproxpropyl trimethoxysilane (believe in Chemical company system) 123.2g, benzyl tetraethyl (pure chemical company) 0.8g, butyl acetate (pure chemical company system) 100g, while stirring while temperatureing to 60 ° C to dissolve, heating to 120 The reaction was reacted for 4 hours, thereby obtaining 4- [2-hydroxy-3- [3- (trimethoxysilyl) propoxy] propoxy] -2, 2 'of the ultraviolet absorber. 4'-trihydroxybenzophenone solid component concentration of 63% by mass of meth...

example 1

[0273] Add a silylating ultraviolet absorber 12.8 g, tetraethoxysilane 15.3g, SiO 2 Particle dispersion 0.7 g, Solmix AP-1 50.6 g, pure water 19.5 g, SR-SEP 1.1G, maleic acid 0.116g, Nonpol PMA-50W0.081G, BYK307 0.060 g, stirred at 50 ° C for 2 hours, added 1% by mass concentration of nitrite solution 0.1 g, resulting in an antibacterial membrane forming coating liquid having ultraviolet absorption capability (0.01% by mass of the silver content in the solid component of the coating liquid 1).

[0274] Then, a high-thermal radiation absorbing green glass (Asahi-branch system, generally known as UVFL) is applied to the gas, in the atmosphere, in the atmosphere It was dried at 200 ° C for 30 minutes to obtain a glass plate 1 with an antibacterial membrane having ultraviolet absorption capacity.

example 2

[0276] The 1% by mass concentration of nitrogen solution was 0.7 g, and the pure water was 19.0 g, except that the same operation as described in Example 1 was obtained, and the coating liquid having ultraviolet absorbent capacity was obtained. 2 (the coating liquid) The silver content in the solid component of 2 is 0.05% by mass). Further, the antibacterial membrane forming coating liquid 1 is formed of an antibacterial film to form a coating liquid 2, except that the same operation as in Example 1 is obtained, and a glass plate 2 having ultraviolet absorbing ability is obtained.

Abstract

The present invention provides a liquid composition capable of producing automotive glass having not only ultraviolet blocking properties but also antibacterial properties, and an antibacterial article using the liquid composition. The liquid composition contains an ultraviolet absorber (a), a binder component (b), an antibacterial active substance (c) and a liquid medium (d), and the ultraviolet absorber (a) contains One or more of compound, triazine compound and benzotriazole compound, the binder component (b) is mainly composed of silicon oxide matrix raw material components, and the antibacterial active substance (c) is selected from silver , copper, zinc, and at least one of hydrolyzable silicon compounds with antibacterial active groups, the antibacterial article (1) has a substrate (2) and ultraviolet rays formed by using the above-mentioned liquid composition on the surface of the substrate (2) Absorption and antibacterial film (3).

Description

Technical field [0001] The present invention relates to liquid compositions and antibacterial items, and more particularly to liquid compositions suitable for forming a film having ultraviolet absorbing capacity and antimicrobial film and an antimicrobial article having ultraviolet absorbing ability using the liquid composition. Background technique [0002] In recent years, the display device with touch panel has taken into account for health. For example, the use frequency of the frame of the mobile device is much higher, and therefore, the possibility of bacteria is high, and excellent antimicrobial is required. In addition, a large number of non-specific people's ticket machine, bank ATM, equipment used in the medical facility, etc. The display device of the touch panel is high due to their use environment, and there is a high possibility of various bacteria. Therefore, Has the same problem. [0003] For example, in Patent Document 1, a method of manufacturing an antibacteria...
