- a laminated glass obtained by cutting an interlayer film for laminated glass unwound from a roll into an appropriate size and sandwiching the interlayer film for laminated glass between at least two glass plates.
- the body is put into a rubber bag and sucked under reduced pressure, pre-pressed while deaerating air remaining between the glass plate and the intermediate film, and then subjected to main pressure bonding by heating and pressurizing in an autoclave, for example (rubber back Method) or a laminated body in which an interlayer film for laminated glass is laminated between at least two glass plates is conveyed to a constant temperature by passing the laminated body through a heating zone while being conveyed using a conveyor.
- Patent Document 1 a method of the present adhesive under high temperature and high pressure in an autoclave (nip roll method) has been performed.
- the present invention provides an interlayer film for laminated glass that does not jump out from between glass plates when a pre-bonding step is performed in the production of laminated glass, and a laminated glass using the interlayer film for laminated glass.

- the present invention is described in detail below.
- the present inventors examined the cause of the phenomenon that the interlayer film for laminated glass jumps out between the two glass plates at the time of pre-bonding. As a result, it was found that the interlayer film for laminated glass contracted and expanded when heated during pre-bonding. That is, in the production of an interlayer film for laminated glass, a resin film obtained by extruding a raw resin composition from an extruder is wound using a roll. Moreover, when embossing is performed on the surface of the interlayer film for laminated glass, the film is passed between the embossing rolls while applying temperature. Through such a process, the stress is accumulated in the interlayer film for laminated glass because it is fixed while being pulled in the flow direction.
- the interlayer film for laminated glass is heated to about 50 to 80 ° C. and becomes soft.
- the softened interlayer film for laminated glass is subjected to a force to shrink in the flow direction and a force to expand in the width direction due to the accumulated stress. It was thought that the phenomenon of jumping out between two glass plates occurred.

In addition, it can confirm by the winding direction of the roll-shaped body of this intermediate film for laminated glasses. This is because the roll-shaped body of the interlayer film for laminated glass is wound up in the flow direction of the film during the production of the interlayer film for laminated glass. This is because the flow direction of the membrane is the same.

なお、合わせガラス用中間膜の流れ方向は、例えば、以下の方法によって確認することができる。即ち、合わせガラス用中間膜を140℃の恒温槽に30分保管した後、フィルムの平行方向と垂直方向の収縮率が大きいほうが流れ方向であることにより確認することができる。他にも、該合わせガラス用中間膜のロール状体の巻取り方向によって確認することができる。これは、合わせガラス用中間膜のロール状体は、合わせガラス用中間膜製造時の膜の流れ方向に巻き取られることから、ロール状体の巻取方向と、合わせガラス用中間膜製造時の膜の流れ方向とが同一であることによる。
図1(a)では、まずロール状体2から、合わせガラス用中間膜1を引き出す。このとき、引き出した方向が合わせガラス用中間膜の流れ方向であり、該流れ方向に対して直交する同一平面状の方向が幅方向である。
引き出した合わせガラス用中間膜は、流れ方向に20cmの位置で切断して、20cm×膜幅(通常は100cm)の試験用サンプル3を得る(図1(b))。試験用サンプル3は、20℃、30%RHの条件下で平面状に置いて、24時間養生させた後に測定に供することが好ましい。
養生後に、20℃、30%RH条件下、試験用サンプル3上に少なくとも3点以上の標線を記入する。図1(b)においては、試験用サンプル3上の3カ所に十字状の標線41、42、43を記入した。各々の標線は、十字状の線が各々合わせガラス用中間膜の流れ方向及び幅方向に15cmの長さで記入する。図1(b)においては、標線41は試験用サンプル3の流れ方向及び幅方向の中央部に記入し、標線42、43は、試験用サンプル3の流れ方向の中央部、幅方向の端部付近に記入した。ただし、標線42、43は、その線の端が試験用サンプル3の幅方向の端部から10cm程度離れるように記入した。
標線を記入した試験用サンプル3を80℃の温水中に10分間浸漬する(図1(c))。温水浸漬後の試験用サンプルは、直ちに20℃以下の水に10分間以上浸漬して冷却することが好ましい(図1(d))。
冷却後の試験用サンプル3を取り出し、表面の水分を軽く拭いた後、標線41、42、43の流れ方向及び幅方向の長さを測定する。測定は、試験用サンプル3を取り出した後、5分以内に行うことが好ましい(図1(e))。
合わせガラス用中間膜の幅方向の膨張率及び流れ方向の収縮率は、下記式(1)及び(2)により算出することができ、少なくとも2カ所の標線で測定して得た値の平均をとって幅方向の膨張率及び流れ方向の収縮率とする。
上記熱可塑性樹脂として、例えば、ポリフッ化ビニリデン、ポリテトラフルオロエチレン、フッ化ビニリデン-六フッ化プロピレン共重合体、ポリ三フッ化エチレン、アクリロニトリル-ブタジエン-スチレン共重合体、ポリエステル、ポリエーテル、ポリアミド、ポリカーボネート、ポリアクリレート、ポリメタクリレート、ポリ塩化ビニル、ポリエチレン、ポリプロピレン、ポリスチレン、ポリビニルアセタール、エチレン-酢酸ビニル共重合体等が挙げられる。なかでも、上記幅方向の膨張率及び流れ方向の収縮率を満たす合わせガラス用中間膜を製造しやすいことから、ポリビニルアセタールが好適である。
上記可塑剤としては、合わせガラス用中間膜に一般的に用いられる可塑剤であれば特に限定されず、例えば、一塩基性有機酸エステル、多塩基性有機酸エステル等の有機可塑剤や、有機リン酸化合物、有機亜リン酸化合物等のリン酸可塑剤等が挙げられる。
上記有機可塑剤として、例えば、トリエチレングリコール-ジ-2-エチルヘキサノエート、トリエチレングリコール-ジ-2-エチルブチレート、トリエチレングリコール-ジ-n-ヘプタノエート、テトラエチレングリコール-ジ-2-エチルヘキサノエート、テトラエチレングリコール-ジ-2-エチルブチレート、テトラエチレングリコール-ジ-n-ヘプタノエート、ジエチレングリコール-ジ-2-エチルヘキサノエート、ジエチレングリコール-ジ-2-エチルブチレート、ジエチレングリコール-ジ-n-ヘプタノエート等が挙げられる。なかでも、トリエチレングリコール-ジ-2-エチルヘキサノエート、トリエチレングリコール-ジ-2-エチルブチレート、又は、トリエチレングリコール-ジ-n-ヘプタノエートを含むことが好ましく、トリエチレングリコール-ジ-2-エチルヘキサノエートを含むことがより好ましい。
上記接着力調整剤としては、例えば、アルカリ金属塩又はアルカリ土類金属塩が好適に用いられる。上記接着力調整剤として、例えば、カリウム、ナトリウム、マグネシウム等の塩が挙げられる。
上記塩を構成する酸としては、例えば、オクチル酸、ヘキシル酸、2-エチル酪酸、酪酸、酢酸、蟻酸等のカルボン酸の有機酸、又は、塩酸、硝酸等の無機酸が挙げられる。
本発明の合わせガラス用中間膜が多層構造である場合には、2層以上の樹脂層として、第1の樹脂層と第2の樹脂層とを有し、かつ、第1の樹脂層と第2の樹脂層とが異なる性質を有することにより、1層だけでは実現が困難であった種々の性能を有する合わせガラス用中間膜を提供することができる。
以下、該遮音中間膜について、より具体的に説明する。
上記遮音層は、ポリビニルアセタールXと可塑剤とを含有することが好ましい。
上記ポリビニルアセタールXは、ポリビニルアルコールをアルデヒドによりアセタール化することにより調製することができる。上記ポリビニルアセタールXは、ポリビニルアルコールのアセタール化物であることが好ましい。上記ポリビニルアルコールは、通常、ポリ酢酸ビニルをけん化することにより得られる。
上記ポリビニルアルコールの重合度の好ましい下限は200、好ましい上限は5000である。上記ポリビニルアルコールの重合度を200以上とすることにより、得られる遮音中間膜の耐貫通性を向上させることができ、5000以下とすることにより、遮音層の成形性を確保することができる。上記ポリビニルアルコールの重合度のより好ましい下限は500、より好ましい上限は4000である。
上記炭素数が4~6のアルデヒドとしては、直鎖状のアルデヒドであってもよいし、分枝状のアルデヒドであってもよく、例えば、n-ブチルアルデヒド、n-バレルアルデヒド等が挙げられる。
上記ポリビニルアセタールXの水酸基量は、水酸基が結合しているエチレン基量を、主鎖の全エチレン基量で除算して求めたモル分率を百分率(モル%)で表した値である。上記水酸基が結合しているエチレン基量は、例えば、JIS K6728「ポリビニルブチラール試験方法」に準拠した方法により、上記ポリビニルアセタールXの水酸基が結合しているエチレン基量を測定することにより求めることができる。
上記保護層は、例えば、ポリビニルアセタールYと可塑剤とを含有することが好ましく、ポリビニルアセタールXより水酸基量が大きいポリビニルアセタールYと可塑剤とを含有することがより好ましい。
上記ポリビニルアルコールは、通常、ポリ酢酸ビニルをけん化することにより得られる。また、上記ポリビニルアルコールの重合度の好ましい下限は200、好ましい上限は5000である。上記ポリビニルアルコールの重合度を200以上とすることにより、合わせガラス用中間膜の耐貫通性を向上させることができ、5000以下とすることにより、保護層の成形性を確保することができる。上記ポリビニルアルコールの重合度のより好ましい下限は500、より好ましい上限は4000である。
上記炭素数が3~4のアルデヒドとしては、直鎖状のアルデヒドであってもよいし、分枝状のアルデヒドであってもよく、例えば、n-ブチルアルデヒド等が挙げられる。
また、合わせガラスの遮音性がより一層向上することから、上記遮音層におけるポリビニルアセタールX100質量部に対する、可塑剤の含有量(以下、含有量Xともいう。)は、上記保護層におけるポリビニルアセタールY100質量部に対する、可塑剤の含有量(以下、含有量Yともいう。)より多いことが好ましく、5質量部以上多いことがより好ましく、15質量部以上多いことが更に好ましく、20質量部以上多いことが特に好ましい。含有量X及び含有量Yを調整することにより、上記遮音層のガラス転移温度が低くなる。結果として、合わせガラスの遮音性がより一層向上する。
上記保護層の厚みのより好ましい下限は300μm、より好ましい上限は700μmである。
具体的には、押出機の金型から吐出された樹脂膜が巻取まで通過する各ロールのスピード差が15%以下となるように調整する。また、金型から吐出された樹脂膜が最初に通るロールを、金型よりも下、かつ、金型よりも流れ方向に対して前にあるように設置する。更に、押出機からの押出量を500~800kg/h、最初に通るロールのスピードを5~10m/分に調整する。これらの押出し条件の制御を行うことにより、上記幅方向の膨張率及び流れ方向の収縮率を満たす合わせガラス用中間膜を得ることができる。
上記ガラス板は、一般に使用されている透明板ガラスを使用することができる。例えば、フロート板ガラス、磨き板ガラス、型板ガラス、網入りガラス、線入り板ガラス、着色された板ガラス、熱線吸収ガラス、熱線反射ガラス、グリーンガラス等の無機ガラスが挙げられる。また、ガラスの表面に紫外線遮蔽コート層が形成された紫外線遮蔽ガラスも用いることができる。更に、ポリエチレンテレフタレート、ポリカーボネート、ポリアクリレート等の有機プラスチックス板を用いることもできる。
上記ガラス板として、2種類以上のガラス板を用いてもよい。例えば、透明フロート板ガラスと、グリーンガラスのような着色されたガラス板との間に、本発明の合わせガラス用中間膜を積層した合わせガラスが挙げられる。また、上記ガラス板として、2種以上の厚さの異なるガラス板を用いてもよい。
ポリビニルブチラール樹脂(水酸基の含有率30モル%、アセチル化度1モル%、ブチラール化度69モル%、平均重合度1700)100重量部に対し、可塑剤としてトリエチレングリコール-ジ-2-エチルヘキサノエート(3GO)40重量部と、紫外線遮蔽剤として2-(2’-ヒドロキシ-3’-t-ブチル-5-メチルフェニル)-5-クロロベンゾトリアゾール(BASF社製、「Tinuvin326」)0.5重量部と、酸化防止剤として2,6-ジ-t-ブチル-p-クレゾール(BHT)0.5重量部とを添加し、ミキシングロールで充分に混練し、樹脂組成物を得た。
得られた樹脂組成物を押出機により押出して、幅100cm、厚み770μmの単層の合わせガラス用中間膜を得て、ロール状に巻き取った。この際、リップ金型としてリップの間隙が1.0mmのものを用い、リップ金型から吐出された樹脂膜が巻取まで通過する各ロールのスピード差を15%以下となるように調整し、リップ金型から吐出された樹脂膜が最初に通るロールを、金型よりも下、かつ、金型よりも流れ方向に対して前にあるように設置し、押出機からの押出量を700kg/h、最初に通るロールのスピードを7m/分に調整した。
押出し条件、リップ金型から吐き出された樹脂膜が巻取りまで通過する各ロールのスピード差、最初に通るロールのスピードを変更した以外は、実施例1と同様にして合わせガラス用中間膜を得た。
(保護層用樹脂組成物の調製)
ポリビニルブチラール樹脂(水酸基の含有率30モル%、アセチル化度1モル%、ブチラール化度69モル%、平均重合度1700)100重量部に対し、可塑剤としてトリエチレングリコール-ジ-2-エチルヘキサノエート(3GO)40重量部と、紫外線遮蔽剤として2-(2’-ヒドロキシ-3’-t-ブチル-5-メチルフェニル)-5-クロロベンゾトリアゾール(BASF社製、「Tinuvin326」)0.5重量部と、酸化防止剤として2,6-ジ-t-ブチル-p-クレゾール(BHT)0.5重量部とを添加し、ミキシングロールで充分に混練し、保護層樹脂組成物を得た。
ポリビニルブチラール樹脂(水酸基の含有率23モル%、アセチル化度12モル%、ブチラール化度65モル%、平均重合度2300)100重量部に対し、可塑剤としてトリエチレングリコール-ジ-2-エチルヘキサノエート(3GO)60重量部を添加し、ミキシングロールで充分に混練し、遮音層用樹脂組成物を得た。
遮音層用樹脂組成物及び保護層用樹脂組成物を共押出することにより、厚さ方向に保護層(厚さ355μm)、遮音層(厚さ100μm)、保護層(厚さ356μm)の順に積層された三層構造の合わせガラス用中間膜を得て、ロール状に巻き取った。この際、リップ金型としてリップの間隙が1.0mmのものを用い、リップ金型から吐出された樹脂膜が巻取まで通過する各ロールのスピード差を15%以下となるように調整し、リップ金型から吐出された樹脂膜が最初に通るロールを、金型よりも下、かつ、金型よりも流れ方向に対して前にあるように設置し、押出機からの押出量を700kg/h、最初に通るロールのスピードを7m/分に調整した。
合わせガラス用中間膜の構造を保護層(厚さ350μm)、遮音層(厚さ100μm)、保護層(厚さ350μm)の順に積層された三層構造に変更し、押出し条件、リップ金型から吐き出された樹脂膜が巻取りまで通過する各ロールのスピード差、最初に通るロールのスピードを変更した以外は、実施例6と同様にして合わせガラス用中間膜を得た。
実施例及び比較例で得られた合わせガラス用中間膜について、以下の方法により評価を行った。
結果を表1に示した。
図1に記載した方法に基づいて、80℃温水浸漬後の合わせガラス用中間膜の膨張率、収縮率を測定した。即ち、ロール状体から、合わせガラス用中間膜を引き出し、流れ方向に20cmの位置で切断して、20cm×100cmの試験用サンプルを得た。得られた試験用サンプルを、20℃、30%RH以下の条件下で平面状に置いて、24時間養生させた。なお、合わせガラス用中間膜を80℃の温水に浸漬する際は、浸漬時に皺が発生しないように注意しながら、水槽の底に沈めた。
次いで、試験用サンプル上の3カ所(流れ方向の中央部、幅方向の各端部から10cm離れた部分)に、長さ15cmの十字状の標線を記入した。
標線を記入した試験用サンプルを80℃の温水中に10分間浸漬し、次いで20℃以下の水に10分間以上浸漬して冷却した。冷却後の試験用サンプルを取り出し、直ちに表面の水分を軽く拭き、5分以内に各標線の流れ方向及び幅方向の長さを測定した。
合わせガラス用中間膜の幅方向の膨張率及び流れ方向の収縮率は、上記式(1)及び(2)により算出し、3カ所の標線での測定値の平均をとって幅方向の膨張率及び流れ方向の収縮率とした。
