添加して作成する。しかし、このガラスを作成する場合
、ガラスの組成から変える必要があり、そのため、大変
手間がかかり、コスト高になる。Generally, UV-cut glass and organic paints containing UV absorbers are used to block UV rays.
Each of them has the following problems: (1) When using ultraviolet-cut composition glass Ultraviolet-cut composition glass is prepared by adding CeO2, FeO, TiO2, etc. to a normal glass composition. However, when creating this glass, it is necessary to change the composition of the glass, which requires a lot of effort and increases costs.

る可能性がある。■ When using an organic paint with added ultraviolet absorber An organic paint with added ultraviolet absorber is a paint made by adding an ultraviolet absorber to an organic resin paint. However, this paint does not have very good adhesion to glass, and there is a possibility that the paint film will peel off or smudge.
また、高温雰囲気で使用すると塗膜が変色する。Additionally, the paint film will change color if used in a high temperature atmosphere.
この発明は、このような事情に鑑みなされたもので、上
記のごとき問題の生じない紫外線カットガラス製品の製
法を提供することを目的とする。The present invention was made in view of the above circumstances, and an object of the present invention is to provide a method for manufacturing ultraviolet ray-blocking glass products that does not cause the above-mentioned problems.
上記目的を達成するため、この発明は、成形直後の高温
のガラス成形品に対して、有機金属化合物を含む塗料を
少なくとも１層塗装する紫外線カットガラス製品の製法
をその要旨とするものである。In order to achieve the above object, the gist of the present invention is a method for producing an ultraviolet-blocking glass product, in which at least one layer of paint containing an organic metal compound is applied to a high-temperature glass molded product immediately after molding.
すなわち、この発明では、（ａ）成形直後のガラス成形

品質（密着性、耐変色性）が良い。That is, in this invention, (a) the glass molded product is simply coated with paint immediately after molding, so there is no need to change the composition of the glass fabric, the alcohol is cheap, and the slow cooling of the glass globe is This can be done at the same time as the baking process, and since the paint contains an organic metal compound, the quality of the paint film (adhesion, color fastness) is good.
次に、これを詳しく説明する。Next, this will be explained in detail.
成形直後のガラス成形品は、生地ガラス温度が３００〜
７００℃であることが好ましい。通常、成形直後のガラ

置によって温度が急激に低下する。しかし、生地ガラス
の温度が３００℃未満になると、生地ガラスの割れにつ
ながるようになるからである。Immediately after molding, the glass molded product has a raw glass temperature of 300~300°C.
Preferably the temperature is 700°C. Normally, the temperature of the raw glass of a glass molded product immediately after molding is 700° C. or lower, and the temperature drops rapidly when left standing. However, if the temperature of the raw glass becomes less than 300°C, the raw glass may break.
成形直後のこの高温のガラス成形品に塗装が行われる。Immediately after molding, this high-temperature glass molded product is painted.
これによって、塗布された塗膜の焼き付けが、高温のガ

みでは充分な焼き付けができず、加温を必要とする場合
も、ガラス成形品の廃熱を有効利用している点で変わり
はないので、この発明の範囲に入る。As a result, the applied coating film is baked using the heat of the high-temperature glass molded product, thereby improving thermal efficiency. However, even if the temperature or amount of heat of the glass molded product is low and it is not possible to bake it sufficiently with that alone and heating is required, there is no difference in that the waste heat of the glass molded product is effectively used. falling within the scope of this invention.

Ｃｅ、Ｆｅ、Ｔｉおよび■としたのは、それらの金属が
他の金属に比べてよく紫外線を吸収するからである。ま
た、それらの有機金属化合物は、混合物の形で使用され
ても同じ効果が得られる。The paint applied to the above-mentioned glass molded product contains an organic metal compound. The metal of the organometallic compound is C
Preferably, they are e, Fe, 'ri and ■. The reason for using the organometallic compound here is that it can easily form a metal oxide film with good adhesion when applied to a high-temperature glass molded product. Furthermore, the reason why the metals of the organometallic compound are Ce, Fe, Ti, and (2) is that these metals absorb ultraviolet rays better than other metals. Furthermore, the same effect can be obtained even when these organometallic compounds are used in the form of a mixture.

を多くすることが好ましい。In addition, by applying at least one layer of these metal oxide films or mixed metal oxide films, the UV-cutting effect is exhibited, and the effect becomes more pronounced by increasing the number of layers or film thickness. . However, if the film thickness is too thick, the adhesion will deteriorate, so 1) 'iJ film thickness is 3
000 Å or less, and it is preferable to increase the number of layers in order to improve the UV-cutting effect.
塗料は、有機金属化合物を適当な有機溶媒に溶解し、必
要とあらば水、酸などを添加して作る。Paints are made by dissolving an organometallic compound in a suitable organic solvent and adding water, acid, etc., if necessary.
塗装方法は、何ら限定はしないが、被塗物が高温なため
、スプレーで行うのが妥当である。The coating method is not limited in any way, but since the object to be coated is at a high temperature, spraying is appropriate.
有機溶媒が可燃性の場合、溶媒への引火防止のために、
塗装は、窒素雰囲気で行うことが望ましい。If the organic solvent is flammable, to prevent the solvent from catching fire,
It is desirable that the coating be performed in a nitrogen atmosphere.
