Abstract

(57) [Summary] [Purpose] To provide functional glass with high durability and good appearance. [Structure] A ceramic print 6 is formed on the inside of the outer glass 1 of a laminated glass in which an outer glass 1 and an inner glass 3 are laminated with an interlayer film 2 interposed therebetween, and a functional print 4 is provided on top of the laminated glass. The functional print 4 is made invisible from the outside. It is also possible to form a conductive heat ray reflective film 7 on the intermediate film side of the inner glass plate 3 and to combine this heat ray reflective film 7 and the functional print 4 to function.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a functionally printed glass for automobiles.

0002

[Conventional technology]

Functional printing on parts of automobile windshields, mainly raindrop and humidity sensors Conventionally, when constructing functional prints for (Refer to Japanese Unexamined Patent Publication No. 160635/1983). In this case, the transparency of the glass It had the advantage of being able to form a conductive film while maintaining the same properties.

0003

[Problem that the idea aims to solve]

However, since conventional technology uses a transparent conductive film, the following problems arise: There was an issue. 1. When constructed on the exterior of a vehicle, the durability of the membrane is insufficient. 2. The conductive film must be thin in order to maintain visible light transmittance of 70% or more. It is difficult to lower the membrane resistance value.

0004 The present invention attempts to solve the problems of the prior art.

[0005]

[Means to solve the problem]

This invention was made to solve the above-mentioned problems, and it Laminated glass that is laminated with glass through an interlayer film, in contact with the interlayer film of the outer glass. A ceramic print is formed on the side, and the side in contact with the intermediate film of the ceramic print We provide glass with functional prints, which is characterized in that functional prints are formed on the glass. This is what we provide.

[0006] FIG. 1 is a sectional view showing an example of the present invention. The outside of the car is shown at the top of the diagram. A ceramic print 6 is formed around the inside of the vehicle on the outer glass 1 of the laminated glass, and the A functional print 4 is formed on a part of the ceramic print. middle on its inside An inner glass plate 3 of laminated glass is bonded via a film 2.

[0007] In the present invention, a conductive heat ray reflective film 7 is further provided on the outer side of the inner glass 3 of the laminated glass. If provided, the functions of the heat ray reflective film 7 and the functional print 4 may be mutually inhibited. It is also possible to use the heat ray reflective film 7 as an electrode.

[0008] Functional print 4 and ceramic print 6 are on the lower windshield wiper. -It is installed near the storage area so that it does not become a nuisance when viewed from inside the car. is preferable. Furthermore, the heat ray reflective film 7 is provided over almost the entire surface of the windshield. Preferably.

[0009]

[Effect]

The ceramic print 6 on the outer glass 1 has the function of hiding the functional print 4. have. This eliminates the need for the functional print 4 to be transparent, making it thicker and non-transparent. It becomes possible to use transparent materials.

0010 Functional print 4 is a printed electrode with conductivity, and has electrical capacitance, resistance value, etc. A sensor machine that detects raindrops and condensation on the exterior surface of laminated glass by detecting Perform Noh.

[0011] In addition, by combining the functional print 4 and the heat ray reflective film 7, similar sensors can be used. -Can also perform functions.

0012 In addition, the functional print 4 can also be provided with a heating function for melting ice and snow, if desired. It is also possible to optimize the printed pattern and perform wiring etc.

【Example】

[Example 1] After cutting and chamfering 2mm thick bronze glass and 2mm thick clear glass, ceramic Screen print color ink on the periphery of the bronze glass and dry it to create a ceramic Form a ceramic print and then add silver paste to a portion of the ceramic print. Printed and dried.

[0014] Heat-forming bronze glass as outer glass and clear glass as inner glass. At the same time, the print was fired. Two pieces of glass are laminated with an interlayer film in between and bonded together to form glass. Electrodes were taken out from the silver print.

[0015] The silver print (functional print) on the completed laminated glass is placed between the two extraction electrodes. It constituted a capacitance, which was 500 pF. Place this glass in a low temperature and high humidity environment However, condensation occurred and the capacitance changed to 550 pF. Due to this characteristic, condensation It was also found possible to detect raindrops.

[0016] [Example 2] Heat molding and baking were carried out in the same manner as in Example 1. Then, polish the outside of the inner glass. After polishing and cleaning, a conductive heat ray reflective film consisting of three layers (ZnO(400Å)/Ag(100Å)/ZnO(400Å) Å) ) was deposited.

[0017] Two pieces of glass are laminated and crimped together with the heat-reflecting film on the inside, and silver print, Electrodes were taken out from the heat-reversed membrane.

[0018] The completed laminated glass has a visible light transmittance of 74% and functions as heat reflective glass. had.

[0019] Further, there was no conduction between the heat ray reflective film and the silver printed electrode. two silver prints One of the electrodes was connected to a heat ray reflective film, and there was a capacitance of 1100pF between the two electrodes. . When water droplets were attached to the axial surface of this glass, the value changed to 1160 pF, but inside the car No change was observed even when it was attached to the surface. This characteristic makes it possible to detect raindrops without being affected by dew condensation on the inside of the car. won.

[0020]

[Effect of the idea]

This invention achieves high durability by enclosing functional prints in laminated glass. Visible light transmittance can be improved by holding and configuring on ceramic print. There is no need to increase the resistance, and a low resistance value can be obtained due to the thick film.
