【０００１】[0001]
本考案は高耐久性紫外線遮断ガラスに関し、更に詳しくは自動車用窓ガラスと して適用可能な高耐久性紫外線遮断ガラスに関する。 The present invention relates to a highly durable ultraviolet blocking glass, and more particularly to a highly durable ultraviolet blocking glass applicable as a window glass for automobiles.
【０００２】[0002]
最近、自動車の内装材に使用されているウール、レザー等の高級天然素材が太 陽光線に照射されて劣化するのを防止したり、室内にいる人の日焼けを防止する ために紫外線を遮断するガラスが、自動車の窓ガラスや店舗のショーウィンドウ に用いられるようになってきている。 Recently, high-quality natural materials such as wool and leather used for interior materials of automobiles are prevented from being deteriorated by being exposed to sunlight, and UV rays are blocked in order to prevent sunburn of people in the room. Glass is being used for automobile windows and shop show windows.
【０００３】 このような紫外線遮断ガラスとしては、ガラス中にＣｅ，Ｖ，Ｆｅ，Ｐｂ，Ｔ ｉなどの紫外線を吸収するイオンを含ませたガラスがある（特開昭６３−３０７ １４２号公報及び特開平３−１８７９４６号公報参照）。As such an ultraviolet blocking glass, there is a glass in which ions such as Ce, V, Fe, Pb, and Ti that absorb ultraviolet rays are contained in the glass (Japanese Patent Laid-Open No. 63-307142 and (See Japanese Patent Laid-Open No. 3-187946).
【０００４】 また、透明な無機物質の紫外線吸収剤をガラス板にコーティングしたものがあ る（特開平１−２０５１７９号公報、特開平３−２２３１１１号公報及び特開平 １−１９３０６号公報参照）。There is also a glass plate coated with a transparent inorganic ultraviolet absorber (see Japanese Patent Laid-Open Nos. 1-205179, 3-223111, and 1-19306).
【０００５】 更に、有機紫外線吸収剤を透明な塗料中に分散させたものを基材の上に塗布し たものがある（特開平３−２６５５４５号公報参照）。Further, there is one in which an organic ultraviolet absorber is dispersed in a transparent coating material and applied on a substrate (see Japanese Patent Laid-Open No. 3-265545).
【０００６】[0006]
上記の有機紫外線吸収剤を塗料中に含有させたものを基材に塗布して、紫外線 吸収性能を付与したものは、紫外線吸収剤が劣化し易く寿命が短いこと、塗布膜 と基材との付着力が小さく実用的強度が不足していること、あるいは表面の耐摩 耗性が良くないことのような耐久性の面での問題点があった。 The one in which the above-mentioned organic UV absorber is contained in the coating material is applied to the base material to impart the UV absorbing property, the UV absorber is easily deteriorated and has a short life. There was a problem in terms of durability such as low adhesion and lack of practical strength, or poor surface abrasion resistance.
【０００７】 本考案の目的は、上記した問題点の解消にあり、可視域の光学特性をほとんど 低下させることなく紫外線透過を効率よく遮断し、かつ自動車用窓ガラスのよう な大きな耐久性が要求される用途に用いて有用な高耐久性紫外線遮断ガラスを提 供することである。The object of the present invention is to solve the above-mentioned problems, and it is required to efficiently block ultraviolet light transmission without substantially deteriorating the optical characteristics in the visible region and to have a large durability like a window glass for an automobile. It is to provide a highly durable ultraviolet blocking glass which is useful for various applications.
【０００８】[0008]
本考案の高耐久性紫外線遮断ガラスは、ガラス板に、シランカップリング剤を 重縮合させたプライマー処理層を被覆し、前記プライマー処理層の上に有機紫外 線吸収剤を含有するＳｉＯ2 の紫外線吸収層を被覆し、前記紫外線吸収層の上に ＳｉＯ2 の保護層を被覆してなることを特徴とするものである。The highly durable UV-blocking glass of the present invention is obtained by coating a glass plate with a primer treatment layer in which a silane coupling agent is polycondensed, and coating the primer treatment layer with an organic UV absorber containing SiO 2 UV rays. An absorption layer is coated, and a protective layer of SiO 2 is coated on the ultraviolet absorption layer.
【０００９】 本考案に係るガラス板は、特にその組成が限定されることがない。たとえば、 ソーダライムシリカ組成のフロートガラス板や、それを加熱曲げ加工したもの、 風冷強化したものは好適に用いられる。The composition of the glass plate according to the present invention is not particularly limited. For example, a float glass plate having a soda lime silica composition, a product obtained by heating and bending it, and a product tempered by air cooling are preferably used.
【００１０】 本考案に係るプライマー処理層は、０．５〜３．０％のシランカップリング剤 を含むアルコール溶液をガラス板に塗布し、１５０〜２５０℃で１０〜６０分間 加熱して形成される。ここで、シランカップリング剤としては、通常知られてい るものであれば特に制限されず、例えば、γ−アミノプロピルトリエトキシシラ ンのようなアミノシランが挙げられる。このプライマー処理層を設けるに先立ち 、ガラス表面は酸処理をするのがプライマー処理層とガラス板との密着性を大き くする上で好ましい。酸処理の方法としては、１０〜３０％の塩酸、硝酸、硫酸 などの酸水溶液にガラスを漬ける方法が用いられる。The primer treatment layer according to the present invention is formed by applying an alcohol solution containing 0.5 to 3.0% of a silane coupling agent to a glass plate and heating at 150 to 250 ° C. for 10 to 60 minutes. It Here, the silane coupling agent is not particularly limited as long as it is commonly known, and examples thereof include aminosilane such as γ-aminopropyltriethoxysilane. Prior to providing this primer treatment layer, it is preferable to treat the glass surface with an acid in order to increase the adhesion between the primer treatment layer and the glass plate. As the acid treatment method, a method of immersing glass in an aqueous acid solution of 10 to 30% hydrochloric acid, nitric acid, sulfuric acid or the like is used.
【００１１】 本考案に係る紫外線吸収層は、コロイダルシリカ等のＳｉＯ2 微粒子および有 機シラン化合物の加水分解重縮合物を主成分とする層に有機紫外線吸収剤が含有 されて構成されている。紫外線吸収層の形成には、ハードコート溶液を調製し、 その溶液をプライマー処理層の上にディップ法、スプレー法、フロー法などの公 知の方法で塗布し、１５０℃〜２５０℃の温度で５分〜３０分間加熱することに より行うことができる。ハードコート溶液としては、コロイダルシリカ、メチル トリメトキシシラン、グリシドキシプロピルトリメトキシシランおよびカルボン 酸を主成分とし、溶媒として水、ブチルアルコール、メチルアルコール、１−メ トキシ−２−プロパノールなどの全部または一部を含む公知のハードコート溶液 が好適に用いられる。また、有機紫外線吸収剤としては、２，４−ジヒドロキシ −ベンゾフエノン、２，２’，４，４’テトラヒドロキシ−ベンゾフエノン（以 下２２’４４’ＴＨＢＰと略す）、２−（２’−ヒドロキシ−５’−メチルフエ ニル）−ベンゾトリアゾール、２−（２’−ヒドロキシ−３’−ｔ−ブチル−５ ’−メチルフエニル）−５−クロロベンゾトリアゾールのうち少なくとも１種の ものが挙げられる。The ultraviolet absorbing layer according to the present invention is composed of a layer containing SiO 2 fine particles such as colloidal silica and a hydrolytic polycondensate of an organic silane compound as a main component and an organic ultraviolet absorbing agent. To form the ultraviolet absorbing layer, a hard coat solution is prepared, and the solution is applied on the primer-treated layer by a known method such as a dipping method, a spray method, or a flow method, and the temperature is from 150 ° C to 250 ° C. It can be performed by heating for 5 minutes to 30 minutes. The hard coat solution is mainly composed of colloidal silica, methyltrimethoxysilane, glycidoxypropyltrimethoxysilane and carboxylic acid, and as a solvent, all of water, butyl alcohol, methyl alcohol, 1-methoxy-2-propanol and the like. Alternatively, a known hard coat solution containing a part thereof is preferably used. The organic UV absorbers include 2,4-dihydroxy-benzophenone, 2,2 ', 4,4' tetrahydroxy-benzophenone (hereinafter abbreviated as 22'44'THBP), 2- (2'-hydroxy-). At least one of 5'-methylphenyl) -benzotriazole and 2- (2'-hydroxy-3'-t-butyl-5'-methylphenyl) -5-chlorobenzotriazole can be mentioned.
【００１２】 ソーダライムシリカ組成のフロートガラスなどの透明ガラス板を用いて、紫外 線遮断性が大きく、かつ、可視光線透過率を用いるガラスとほぼ同じ高耐久性紫 外線遮断ガラスとするには、紫外線吸収剤の重量％をｃとしたとき、２５≦ｃｔ ≦６０の範囲となるようにすることが好ましい。ｃｔが６０を超えると、ガラス 板の色調とそのガラス板を用いて得られる本考案と色調との色差を、色度座標（ ｘ，ｙ）の差Δｘ，Δｙで表したとき、肉眼ではその差が認めにくい値であるΔ ｘ≦０．００５、Δｙ≦０．００５にはならない。ｃｔが２５未満では、紫外線 の遮蔽効果が弱くなり、自動車の内装材の日焼けなどによる劣化を防止しにくい 。To use a transparent glass plate such as a soda lime silica composition float glass to have a high ultraviolet blocking property and to have a highly durable ultraviolet blocking glass that is almost the same as glass using visible light transmittance, When the weight% of the ultraviolet absorber is c, it is preferable that the range is 25 ≦ ct 2 ≦ 60. When ct exceeds 60, when the color difference between the color tone of the glass plate and the present invention obtained by using the glass plate and the color tone is represented by the difference Δx, Δy of the chromaticity coordinates (x, y), the difference is visible to the naked eye. Differences are hard to be recognized, and Δx ≦ 0.005 and Δy ≦ 0.005 are not satisfied. When ct is less than 25, the ultraviolet ray shielding effect is weakened, and it is difficult to prevent deterioration of the interior materials of automobiles due to sunburn.
【００１３】 ｃｔが前記の範囲内であれば、紫外線透過率を２０％以下にすることができる と同時に、可視域の短波長側の透過率が低下し着色が生じることがない。この範 囲は、自動車やショーウィンドウなどの太陽光線があたるところに用いられる紫 外線遮断性能を有する窓ガラスとして有用である。When ct is within the above range, the ultraviolet transmittance can be 20% or less, and at the same time, the transmittance on the short wavelength side in the visible region is lowered and coloring does not occur. This range is useful as a window glass having an ultraviolet ray blocking performance used in places exposed to sunlight such as automobiles and show windows.
【００１４】 また、前記有機紫外線吸収剤の含有率ｃは、通常、１％〜１０％の範囲で用い るのが良く、１〜５％の範囲で用いるのが更に良い。また、紫外線吸収層の厚み ｔは、紫外線吸収層自体にある程度の摩耗強度をもたせるために、ｔ≧５が好ま しい。Further, the content c of the organic ultraviolet absorber is usually preferably in the range of 1% to 10%, and more preferably in the range of 1% to 5%. Further, the thickness t of the ultraviolet absorbing layer is preferably t ≧ 5 so that the ultraviolet absorbing layer itself has some wear strength.
【００１５】 本考案に係る保護層は、ＳｉＯ2 からなる。保護層の厚みは、１００〜３００ ｎｍとするのが好ましい。１００ｎｍ未満では耐摩耗性の実用強度を得るのに必 ずしも十分でない。３００ｎｍを超えると保護層自体にクラックを生じるおそれ がある。なお、必要に応じて、Ａｌ2 Ｏ3 、ＺｒＯ2 、ＴｉＯ2 、ＳｉＯＮ（シ リコンオキシナイトライド）などの透明な酸化物、酸窒化物を保護層に用いるこ とができる。The protective layer according to the present invention is made of SiO 2 . The thickness of the protective layer is preferably 100 to 300 nm. If it is less than 100 nm, it is not necessarily sufficient to obtain a practical wear resistance strength. If it exceeds 300 nm, the protective layer itself may be cracked. If necessary, a transparent oxide or oxynitride such as Al 2 O 3 , ZrO 2 , TiO 2 , or SiON (silicon oxynitride) can be used for the protective layer.

本考案の高耐久性紫外線遮断ガラスは、紫外線のみを効率よく吸収する有機紫 外線吸収剤を含有させた紫外線吸収層と耐摩耗性が優れた無機酸化物からなる保 護層とを、保護層が最外側になるように積層し、かつ紫外線吸収層はガラス板に プライマー層を介して大きな接着強度で接着している。かかる積層構造をとるこ とにより、耐摩耗性、耐酸性、耐候性、剥離強度のいずれも大きい実用的な高耐 久性紫外線遮断ガラスが得られる。 The highly durable UV blocking glass of the present invention comprises a UV absorbing layer containing an organic UV absorbing agent that efficiently absorbs only UV rays, and a protective layer made of an inorganic oxide having excellent wear resistance. Are laminated so that they are on the outermost side, and the ultraviolet absorbing layer is adhered to the glass plate with a large adhesive strength via the primer layer. By taking such a laminated structure, it is possible to obtain a practical, highly durable UV-screening glass having large abrasion resistance, acid resistance, weather resistance and peel strength.

以下に、実施例及び比較例を示し、本考案を更に詳しく説明する。なお、図１ は、本考案の一部縦断面図であって、ガラス基板１の上に、プライマー処理層２ 、紫外線吸収層３、ＳｉＯ2 からなる保護層４が順次積層されている。Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. FIG. 1 is a partial vertical cross-sectional view of the present invention, in which a primer treatment layer 2, an ultraviolet absorbing layer 3, and a protective layer 4 made of SiO 2 are sequentially laminated on a glass substrate 1.
【００１８】 実施例１ 厚みが３．４ｍｍの透明フロートガラス板を１５％の硫酸水溶液に１０分間漬 けた後乾燥し、γ−アミノプロピルトリエトキシシランの２％エチルアルコール 溶液をガラス表面に塗布し、２００℃で３０分加熱して、プライマー処理層を形 成した。このプライマー処理層の上に、コロイダルシリカとメチルメトキシシラ ンとプロピオン酸とが紫外線吸収層のベース形成成分として１−メトキシ−２− プロパノール溶媒に含まれる溶液を調製し、この溶液にＴＨＢＰを、加熱処理に より得られる紫外線吸収層中のＴＨＢＰが２重量％となるように紫外線吸収用塗 布液を調製した。この塗布液をプライマー処理層の上に塗布し、２００℃で２０ 分間加熱して、厚さ１２μｍの紫外線吸収層を設けた。さらに、この紫外線吸収 層の上にＳｉＯ2 をターゲットとして高周波スパッタ法により厚みが１００ｎｍ のＳｉＯ2 保護膜を設け、本考案の高耐久性紫外線遮断ガラスを得た。Example 1 A transparent float glass plate having a thickness of 3.4 mm was immersed in a 15% sulfuric acid aqueous solution for 10 minutes and then dried, and a 2% ethyl alcohol solution of γ-aminopropyltriethoxysilane was applied to the glass surface. The sample was heated at 200 ° C. for 30 minutes to form a primer-treated layer. A solution containing colloidal silica, methyl methoxysilane and propionic acid in a 1-methoxy-2-propanol solvent as a base forming component of the ultraviolet absorbing layer was prepared on the primer-treated layer, and THBP was added to the solution. A UV absorbing coating solution was prepared so that THBP in the UV absorbing layer obtained by the heat treatment was 2% by weight. This coating solution was applied on the primer-treated layer and heated at 200 ° C. for 20 minutes to form an ultraviolet absorbing layer having a thickness of 12 μm. Further, a SiO 2 protective film having a thickness of 100 nm was formed on the UV absorbing layer by a high frequency sputtering method using SiO 2 as a target to obtain a highly durable UV blocking glass of the present invention.
