By baking a coating layer of a colored opaque ceramic color composition (frit) in the form of a strip or in various shapes around the window frame of an automobile window glass plate, heating wires around the glass plate inside the car can be heated. The terminals, gaskets, etc. are made so that they cannot be seen from outside the vehicle.
(Refer to Utility Model Publication No. 49-95624). This ceramic color frit coating layer is usually
10~30% heat-resistant colored (usually black) pigment and 70~
Composed of 90% low melting point binder glass.
In its formation, the powder mixture vehicle is kneaded and made into a paste, and then applied to the periphery of a glass plate by screen printing, etc. After the vehicle is dried, the glass plate is softened by strengthening or bending. At the same time as heating to a spot, a coating of ceramic color frit is baked onto the surface of the glass plate. However, in the case of annular products, the mechanical strength of the glass plate after baking is reduced due to the low strength of the ceramic layer fused to the glass surface. The present invention has been made to solve the above-mentioned difficulties, and provides a ceramic color frit composition with almost no decrease in strength. The ceramic color composition according to the present invention consists of a colored heat-resistant pigment powder and a low-melting binder glass powder, and the glass powder has the following composition range.

It is possible to reduce the expansion of the frit by containing it in a proportion of . The reason for limiting the composition of the low melting point binder glass is as follows: PbO is used as a fluxing agent. If it is less than 40%, the glass softening temperature will be high and it will be inappropriate and undesirable under the specified baking conditions.
Moreover, if it exceeds 60%, the coefficient of thermal expansion of the glass becomes too large, making it impossible to obtain the desired strength. It is preferably in the range of 43 to 57 wt%. ZnO: Used as a fluxing agent. If it is less than 0.5%, the effect is small. If it exceeds 9%, crystallization will occur or vitrification will be difficult due to the formation of devitrification during melting. becomes.
It is preferably in the range of 1 to 7 wt%. B 2 O 3 : Used as a fluxing agent. If it is less than 7%, the glass softening point will become too high.
On the other hand, if it is more than 25%, the glass softening point becomes too low and the coefficient of thermal expansion becomes too large, which is not preferable. Preferably 10~
It is 20wt%. SiO 2 : Glass network former,
If it is less than 10%, the glass softening point becomes too low, the chemical durability of the glass decreases, and the coefficient of thermal expansion becomes large, which is not preferable. If it exceeds 50%, the glass softening temperature will become too high. Preferably 13-47%
It is. Al 2 O 3 : Used as a glass melting (devitrification) and crystallization inhibitor. If it is less than 0.5%, the above effect will be weak. If it exceeds 10%, the glass softening temperature will become too high. Preferably 1
~8wt%. R 2 O (Li 2 O, Na 2 O, K 2 O): Although not an essential component, it is used as a low-melting component. However, if it exceeds 5%, the coefficient of thermal expansion becomes too large. It is preferably 3% or less. RO (MgO, BaO, CaO): Used to improve glass meltability. However, if the amount exceeds 5%, the coefficient of thermal expansion increases and the desired low expansion glass cannot be obtained. It is preferably 3% or less. RO 2 (TiO 2 , SnO 2 ): Can be used to improve chemical durability such as water resistance. Even if you introduce more than 3%, the effect will be diminished. Desirably it is 1.5% or less. The coefficient of thermal expansion of the frit is lowered by introducing a low expansion material such as cordierite, zircon, or alumina as a refractory filler. twenty five
If the amount is more than %, the adhesiveness to the glass substrate will decrease. It is preferably 20% or less. As the colored heat-resistant pigment, powders of known black pigments such as MnO 2 , CoO, CdS, and Cr 2 O 3 are used, and are usually contained in an amount of 10 to 30 wt% of the entire composition. After thoroughly mixing these three types of powder, they are kneaded with an appropriate vehicle to form a paste, which is applied to a predetermined location on a glass plate, and after drying, strengthens the glass plate and/or
Or baked during heat treatment for bending. Example (1) Method for preparing ceramic color frit Six types of low melting point binder glasses shown in the attached table are melted by a conventional method, and the melted glass is pulverized. The obtained glass particles are mixed with 20 wt% (additional) of a commercially available black heat-resistant pigment (main components Fe and Mn spinel), and wet-milled by adding an appropriate amount of water in a pot mill. In addition, in the case of sample No. 3, out of the glass powder
Replace 10wt% with zircon powder, and in the case of No. 5
% was replaced with cordierite, and in the case of No. 6, 10 wt% was replaced with zircon powder. Grinding is carried out until the average particle size is 2 μm or less, and the resulting pulverized product is dried.
Prepare a powdered mixture. This powder is mixed with a viscosity-adjusted vehicle (normally ethyl cellulose is added to terpineol to adjust the viscosity) at a ratio of 4:1, and thoroughly kneaded with a kneader to form a paste. (2) Glass Reinforcement Baking Treatment Prepare a plate glass 30 x 30 cm and 5 mm thick, and screen print the ceramic color paste described above on the center of the glass to a size of about 10 cm x 10 cm. The screen was 150mesh, and the thickness of the ceramic color layer after baking was adjusted to 20 to 30μ. After printing, the plate glass is dried in a dryer at about 200℃ for about 10 minutes to bring out the vehicle components. Next, these plate glasses are subjected to air-cooling strengthening treatment using a conventional method. Strengthening is 400mm after heating at 700℃ for 3 minutes.
A method of rapid cooling using H 2 O air pressure was used. Through this strengthening treatment, the applied ceramic color frit is firmly baked onto the surface of the glass plate. (3) Measurement of strength Strength was compared using normal falling ball strength. In the falling ball strength test, a 227 g steel ball was dropped from a height of 50 cm, and if the ball did not break, the height was increased in 10 cm increments, and the height at which the ball broke was taken as the falling ball strength. Note that the data are shown as the average value of each 5 sheets. (4) The results are as shown in the table below: In addition, the table shows the measurement results of the softening point and softening point of the binder glass by DTA, and the coefficient of thermal expansion (50 ~350
°C) is indicated.
