Description

熱線遮蔽中間膜、及びこれを用いた自動車用合わせガラスHeat ray shielding intermediate film and laminated glass for automobiles using the same
 本発明は、遮熱性及び透明性を長期間維持することができる合わせガラス用の熱線遮蔽中間膜に関し、さらに詳しくは、自動車に好適に使用される合わせガラス用の熱線遮蔽中間膜、及び該中間膜を用いた自動車用合わせガラスに関する。
 
The present invention relates to a heat ray shielding intermediate film for laminated glass capable of maintaining heat shielding properties and transparency for a long period of time. More specifically, the present invention relates to a heat ray shielding intermediate film for laminated glass suitably used for automobiles, and the intermediate film. The present invention relates to an automotive laminated glass using a film.
 自動車用の合わせガラスは、一対のガラス板の間に合わせガラス用中間膜を挟み込むことにより製造されており、外部衝撃を受けて破損してもガラスの破片の飛散量が少なく、安全性に優れている。
さらに、自動車用の合わせガラスには、透明性、耐候性、強度、接着力、耐貫通性、衝撃エネルギー吸収性、耐湿性、遮熱性および遮音性等の諸性能に優れている事が要求されている。
 合わせガラスに要求される諸性能の内、遮熱性を高めるためには、一般に熱線と呼ばれる波長780nm以上の赤外線を十分に遮断する事が必要となり、このような熱線を効果的に遮断するために、特許文献1には、六ホウ化物微粒子と、錫ドープ酸化インジウム粒子(ITO粒子)又はアンチモンドープ酸化錫粒子(ATO粒子)などの遮熱粒子を含む合わせガラス用中間膜が、特許文献2には、樹脂との相溶性に優れる有機系熱線遮蔽材料として、フタロシアニン化合物を含有する樹脂からなる熱線遮蔽材が開示されている
Laminated glass for automobiles is manufactured by sandwiching an interlayer film for laminated glass between a pair of glass plates. Even if it is damaged by an external impact, the amount of glass fragments scattered is small and excellent in safety. .
Furthermore, laminated glass for automobiles is required to have excellent performance such as transparency, weather resistance, strength, adhesive strength, penetration resistance, impact energy absorption, moisture resistance, heat insulation and sound insulation. ing.
Of the various performances required for laminated glass, it is necessary to sufficiently block infrared rays having a wavelength of 780 nm or more, which is generally called heat rays, in order to enhance heat shielding properties. In order to effectively block such heat rays. Patent Document 1 discloses an interlayer film for laminated glass containing hexaboride fine particles and heat shielding particles such as tin-doped indium oxide particles (ITO particles) or antimony-doped tin oxide particles (ATO particles). Discloses a heat ray shielding material made of a resin containing a phthalocyanine compound as an organic heat ray shielding material having excellent compatibility with a resin.
 さらに、高エネルギーの光である短波長光が眼にストレスを与え易いことが徐々に知られてきており、この部分の波長をカットして、防眩性を高めることが好ましいといわれている。このような波長を効果的に遮断する為に、例えば、特許文献3には、ネオジム化合物を含有させる技術が、また、特許文献4には、樹脂との相溶性に優れる材料として、ネオジム化合物の代わりにテトラアザポルフィリン化合物を用いて、防眩性を高める技術が開示されている。 Furthermore, it has been gradually known that short-wavelength light, which is high-energy light, is likely to cause stress on the eye, and it is said that it is preferable to increase the antiglare property by cutting the wavelength of this portion. In order to effectively block such a wavelength, for example, Patent Document 3 discloses a technique for containing a neodymium compound, and Patent Document 4 describes a neodymium compound as a material having excellent compatibility with a resin. Instead, a technique for improving the antiglare property using a tetraazaporphyrin compound is disclosed.
 一方、近年では、合わせガラスの遮熱性についての要求が高くなり、ATO、ITOなどの無機系熱線遮熱材料を用いて遮熱性を高めようとすると、該材料の使用量が多くなり、結果として透明性の面で不具合が生じてしまうことがわかった。
 また、本発明者らが検討したところでは、一般的なフタロシアニン系化合物を熱線遮蔽剤として用いた熱線遮蔽中間膜は、長期間の使用により透明性が低下し黄変する傾向にあることがわかったので、高い透明性を維持できないことがわかった。
 
On the other hand, in recent years, there has been an increasing demand for heat shielding properties of laminated glass, and when using an inorganic heat ray heat shielding material such as ATO or ITO to increase the heat shielding properties, the amount of use of the material increases. It has been found that problems occur in terms of transparency.
In addition, as a result of studies by the present inventors, it has been found that a heat ray shielding intermediate film using a general phthalocyanine compound as a heat ray shielding agent has a tendency to decrease in transparency and yellow due to long-term use. Therefore, it was found that high transparency cannot be maintained.

 これによって、遮熱性と透明性に優れ、かつ可視光線透過率が充分に高い合わせガラスを見出した点にある。
Hereinafter, the present invention will be described in detail.
The main feature of the present invention is that a transparent film material made of a thermoplastic resin is used for the intermediate film, and the transparent film material contains a phthalocyanine compound and a tetraazaporphyrin compound.
As a result of investigations by the present inventors, it was found that an intermediate film containing only a general phthalocyanine compound has a tendency to decrease in transparency and yellow due to long-term use. By using such an interlayer film, it has been found that it is possible to maintain high transparency with suppressed yellowing for a long period of time.
In addition, the transparency said by this invention means the thing of the original hue manufactured as an intermediate film.
Furthermore, the visible light transmittance of a laminated glass obtained by providing the interlayer film according to the present invention between two transparent substrates is in the range of 50 to 85%, and the TTS value is 50% or less.
In the present invention, the visible light means a wavelength range of 380 to 780 nm, and the visible light transmittance means a visible light transmittance measured according to JIS R 3212 “Safety Glass Test Method for Automobile”. Further, TTS is an index of heat ray shielding, and means the total solar transmittance as defined in ISO 13837.
Thus, a laminated glass having excellent heat shielding properties and transparency and sufficiently high visible light transmittance is found.
<熱可塑性樹脂>
 本発明に係る中間膜に用いられている熱可塑性樹脂としては、特に限定されるものではなく、従来公知の熱可塑性樹脂を用いることができる。
 例えば、ポリビニルアセタール樹脂、エチレン-酢酸ビニル共重合体樹脂、エチレン-アクリル共重合体樹脂、ポリウレタン樹脂及びポリビニルアルコール樹脂等が挙げられ、これらの熱可塑性樹脂は、単独で用いられても良いし、2種以上が併用されても良い。
 なかでも、優れた透明性、耐候性、強度、接着力、対貫通性、衝撃エネルギー吸収性、耐湿性及び遮熱性等の諸性能のバランスに優れる中間膜が得られることから、可塑化されたポリビニルアセタール系樹脂が最も好ましい。
 上記ポリビニルアセタール系樹脂としては、特に限定されるものではないが、例えば、ポリビニルアルコール(PVA)とアセトアルデヒドを反応させてアセタール化することにより製造できるが、PVAとホルムアルデヒドとを反応させて得られるポリビニルホルマール樹脂、PVAとn-ブチルアルデヒドとを反応させて得られるポリビニルブチラール樹脂(PVB)等も含まれる。
<Thermoplastic resin>
The thermoplastic resin used in the interlayer film according to the present invention is not particularly limited, and conventionally known thermoplastic resins can be used.
Examples include polyvinyl acetal resin, ethylene-vinyl acetate copolymer resin, ethylene-acrylic copolymer resin, polyurethane resin, polyvinyl alcohol resin, and the like, and these thermoplastic resins may be used alone, Two or more kinds may be used in combination.
Above all, it was plasticized because an intermediate film with excellent balance of performance such as excellent transparency, weather resistance, strength, adhesive strength, penetration, impact energy absorption, moisture resistance and heat shielding was obtained. A polyvinyl acetal resin is most preferable.
Although it does not specifically limit as said polyvinyl acetal type-resin, For example, although it can manufacture by making polyvinyl alcohol (PVA) and acetaldehyde react and acetalize, polyvinyl obtained by making PVA react with formaldehyde Formal resins, polyvinyl butyral resin (PVB) obtained by reacting PVA with n-butyraldehyde, and the like are also included.
 上記ポリビニルアセタール系樹脂の合成に用いられるPVAは、特に限定されるものではないが、例えば、ポリ酢酸ビニルをけん化することにより得られる。上記PVAのけん化度は、一般に80~99.8モル%の範囲内であるものが好ましい。
 さらに、特に限定されるものではないが、PVAの平均重合度が200~5000のものが好ましく、より好ましくは500~2,500である。上記重合度が低すぎると、中間膜の強度が弱くなりすぎて、この中間膜を用いて合わせガラスにしたときの耐貫通性や衝撃エネルギー吸収性が不十分となることがあり、上記重合度が高すぎると、得られるポリビニルアセタール系樹脂を中間膜に製膜する際に不具合となることがある。
 上記ポリビニルアセタール系樹脂の合成に用いられるアルデヒドは、特に限定されるものではないが、一般には、炭素数が1~10のアルデヒドが好ましく、より好ましくはプロピオンアルデヒド、n-ブチルアルデヒド又はイソブチルアルデヒドである。なお、これらのアルデヒドは、単独で用いられても良いし、2種以上が併用されても良い。
 上記ポリビニルアセタール系樹脂は、特に限定されるものではないが、水酸基の含有率が15~40モル%の範囲内であることが好ましく、より好ましくは18~35モル%の範囲内である。上記水酸基の含有率が低すぎると、中間膜の接着性が弱くなりすぎることがあり、上記水酸基の含有率が高すぎると、中間膜の柔軟性が低くなり、得られるポリビニルアセタール系樹脂を中間膜に製膜する際に不具合となることがある。

 本発明の合わせガラスの作製方法は、特別なものではなく、通常の合わせガラスの場合と同様の作製方法で良い。すなわち、例えば、二枚の透明基材の間に本発明の中間膜を挟んで真空バッグの中に入れ、この真空バッグ内の圧力が約-65~-100kPaの減圧度となるように減圧吸引しながら温度約70~110℃で予備接着を行った後、さらに、オートクレーブ中で、オートクレーブ内の圧力が約0.98~1.47MPaの減圧度となるように減圧吸引しながら温度約120~150℃で本接着を行うことにより、所望の合わせガラスを得ることができる。
このようにして作製された合わせガラスは、自動車、鉄道車両、航空機、船舶及び建築物等に使用できるが、自動車のフロントガラス、サイドガラス、リアガラス又はルーフガラス等に好適に用いられる。
なお、本発明の合わせガラスの可視光透過率は50~85%の範囲内、好ましくは70~85%の範囲内であることと、TTSの値が50%以下、好ましくは45%以下であることで、遮熱性と透明性により一層優れた合わせガラスとなる。
The method for producing the laminated glass of the present invention is not special and may be the same production method as that for ordinary laminated glass. That is, for example, the interlayer film of the present invention is sandwiched between two transparent substrates and placed in a vacuum bag, and vacuum suction is performed so that the pressure in the vacuum bag is about −65 to −100 kPa. Then, after pre-adhering at a temperature of about 70 to 110 ° C., the pressure in the autoclave is further reduced to about 120 to 110 ° C. while sucking under reduced pressure so that the pressure in the autoclave is about 0.98 to 1.47 MPa. By performing the main bonding at 150 ° C., a desired laminated glass can be obtained.
The laminated glass thus produced can be used for automobiles, railway vehicles, aircraft, ships, buildings, etc., but is preferably used for automobile windshields, side glasses, rear glasses, roof glasses, and the like.
The visible light transmittance of the laminated glass of the present invention is in the range of 50 to 85%, preferably in the range of 70 to 85%, and the TTS value is 50% or less, preferably 45% or less. As a result, the laminated glass is further improved due to its heat shielding properties and transparency.
 以下、実施例により本発明をさらに詳細に説明するが、本発明はこれらに限定されるものではない。 Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.
