- Comparative Example 6 the amount of the anti-blocking agent B added was increased as compared with Comparative Example 5, but the balance between the blocking resistance of the film and the optical characteristics could not be achieved, and neither was satisfied.
- the comparative example 8 did not contain the antiblocking agent B, since the non-crosslinked acrylic polymer C was used in a large amount, the blocking resistance of the film was good, but the gloss was inferior.
- the comparative example 9 did not contain the non-crosslinked acrylic polymer C, the anti-blocking agent B was used in a large amount, so that the blocking resistance of the film was good, but the haze was high and the optical properties were poor.
- the acrylic resin composition of the present invention has good blocking resistance and optical properties, and in particular, a film obtained by molding the acrylic resin composition has weather resistance and design properties and is less likely to generate strain and gauge bands. Therefore, an acrylic resin film having a good appearance can be obtained.
- the acrylic resin film of the present invention can be effectively used for, for example, interior and exterior applications of buildings, road sign cover films, and particularly outdoor applications where direct sunlight is severe.

Abstract
Description
非架橋アクリル重合体C;メタクリル酸メチルc1 50~100質量%を含有する単量体成分の重合体であり、還元粘度が0.2~2L/gである重合体。
アンチブロッキング剤Bの含有量が0.01~0.5質量部であり、
非架橋アクリル重合体Cの含有量が0.1~5質量部である、[1]に記載のアクリル樹脂組成物。
本発明におけるアクリル重合体Aとしては、例えば、下記のゴム含有重合体A1及びゴム非含有重合体A2から選ばれる少なくとも1種を用いることができる。アクリル重合体Aは、ゴム含有重合体A1及びゴム非含有重合体A2からなってもよい。
上記ゴム含有重合体A1の製造方法について、先ず単量体成分を説明し、次いで重合方法を説明する。
単量体成分aは、単量体の総量100質量%を基準にして、アクリル酸アルキルを30質量%以上含む単量体混合物である。単量体成分aは、一段目の重合の原料となることが好ましい。単量体成分aを原料として重合することによってゴム重合体が製造される。
単量体成分bは最終段目の重合の原料となる単量体混合物であり、ゴム含有重合体A1の成形性、機械的性質に関与する成分である。単量体成分bを単独で重合させた際のTgは、耐熱性、成形性等の点から、好ましくは70℃以上120℃以下である。単量体成分bを原料として重合することによって硬質重合体が製造される。
上述のように、単量体成分aを重合してゴム重合体を製造する工程の前に、単量体成分sを乳化重合する工程を含むことができる。単量体成分sを単独で重合して得られる重合体のTgは70~120℃である。単量体成分sとしては単量体成分bと同じものを挙げることができる。
上述のように、単量体成分aを重合してゴム重合体を製造する工程と、該ゴム重合体の存在下に単量体成分bを重合する工程との間に、単量体成分cをゴム重合体の存在下に乳化重合する工程を含むことができる。
ゴム含有重合体A1の製造法としては、例えば、逐次多段乳化重合法が挙げられる。例えば、3段階で重合する方法として、以下の工程が挙げられる。工程1;ゴム重合体を得るための単量体成分a、水及び界面活性剤を混合して乳化液とした状態で重合容器内に供給して重合する。工程2;単量体成分cを重合容器内に供給して重合する。工程3;更に単量体成分b、水及び界面活性剤を混合して乳化液とした状態で重合容器内に供給して重合する。尚、単量体成分cを重合容器内に供給して重合する工程は、必要に応じて行われる工程である。
本発明のアクリル樹脂組成物はアンチブロッキング剤Bを含有する。アンチブロッキング剤Bは、アクリル樹脂組成物中で粒子として存在し、フィルムに製造された際に表面に凹凸を形成する機能を有する。
本発明のアクリル樹脂組成物は下記非架橋アクリル重合体Cを含有する。
本発明のアクリル樹脂組成物は、必要に応じて、添加剤を含むことができる。添加剤としては、例えば、安定剤、滑剤、加工助剤、可塑剤、耐衝撃助剤、発泡剤、充填剤、着色剤、紫外線吸収剤を挙げることができる。
アクリル樹脂組成物は押出機等によって溶融混練され、アクリル樹脂フィルムに成形されることができる。
本実施形態のアクリル樹脂フィルムは、溶融流延法、Tダイ法、インフレーション法等の溶融押出法、カレンダー法等の公知の方法によって製造することができるが、経済性の点からTダイ法が好ましい。成形時の溶融温度は100~280℃であることが好ましい。
本実施形態のアクリル樹脂フィルムの表面には他の樹脂を積層することができる。例えば、高い表面硬度が必要な場合は、本実施形態のアクリル樹脂フィルムよりも表面硬度が高いアクリル樹脂を本実施形態のアクリル樹脂フィルムの表面に配置することができる。具体的には、鉛筆硬度(JIS K5400に基づく測定)が2H以上のアクリル樹脂を用いることによって、耐成形白化、表面硬度(耐擦傷性)、及び耐熱性を備えたアクリル樹脂積層フィルムを得ることができる。
アクリル樹脂フィルムの引張弾性率は800~1500MPaであることが好ましく、900~1300MPaであることがより好ましい。アクリル樹脂フィルムの引張弾性率が800MPa以上である場合、フィルムの適度な剛性を有することができ取扱性を向上させることができる。アクリル樹脂フィルムの引張弾性率が1500MPa以下であると、フィルムの脆性を抑制することができ、取扱性、二次加工性が向上する。
アクリル樹脂フィルムの厚みは20~150μmであることが好ましく、50~100μmであることがより好ましい。積層成形品に用いる場合は、アクリル樹脂フィルムの厚さが20μm以上である場合、成形品により効果的に耐候性を付与することができる。また、アクリル樹脂フィルムの厚さが50μm以上である場合、成形品の外観において充分な深みが得られる。また、複雑な形状に成形する場合、延伸によって充分な厚みが得られる。アクリル樹脂フィルムの厚さが150μm以下であると、フィルムが適度な剛性を有することができ、フィルムのラミネート性、二次加工性が向上する。また、単位面積あたりの質量の点で、経済的に有利になる。更には、製膜性が安定してフィルムの製造が容易になる。
本実施形態のアクリル樹脂フィルムの少なくとも一方の面の算術平均粗さRaは9~16nmである。Raが9nm以上である場合、フィルム同士の貼りつきを防止でき、フィルム外観を向上させることができる。また、アクリル樹脂フィルムのRaが16nm以下である場合、フィルムの透明性等、光学特性が良好になる。
アクリル樹脂フィルムをJIS K7105に基づいて測定したヘーズは、2%以下であることが好ましく、1.5%以下であることがより好ましい。アクリル樹脂フィルムのヘーズが2%以下の場合、例えば、アクリル樹脂フィルムをクリア塗装の代替として用いた場合、透明性が高いため基材の色調を活かすことができる。また、深み感や高級感が向上する。
また、本実施形態のアクリル樹脂フィルムは、基材に積層することができる。例えば、アクリル樹脂フィルムを透明のまま使用して基材上に積層することにより、アクリル樹脂フィルムをクリアな塗装の代替として用いることができる。そのため、基材の色調を活かすことができる。このように基材の色調を活かす用途においては、アクリル樹脂フィルムは、ポリ塩化ビニルフィルムやポリエステルフィルムに比べ、透明性、深み感や高級感の点で優れている。
