本発明のメタクリル系樹脂成形材料は、メタクリル系樹脂ペレットに脂肪酸を外添させたメタクリル系樹脂成形材料であって、脂肪酸の外添量が、メタクリル系樹脂ペレット100質量部に対し0.002質量部以上である。
以下において、メタクリル系樹脂ペレットに脂肪酸を付着させる、または塗布することを「外添」という。一方、メタクリル系樹脂ペレット中に脂肪酸を含有させることを「内添」という。本発明のメタクリル系樹脂成形材料は、メタクリル系樹脂ペレットに対し、脂肪酸を外添させたものである。本発明のメタクリル系樹脂成形材料によれば、高温の金型からの離型性、外観および色調が優れた樹脂成形体を得ることができる。
本発明に従って、メタクリル系樹脂ペレットに脂肪酸を外添させることで、高温の金型からの離型性、外観および色調が優れた樹脂成形体を得ることができるメカニズムは、以下のように考えられる。
本発明のメタクリル系樹脂成形材料に含まれるメタクリル系樹脂ペレットは、メタクリル系樹脂組成物を含有する。本発明におけるメタクリル系樹脂組成物は、少なくともメタクリル系重合体(メタクリル系樹脂と同義である。)を含有する。
メタクリル系重合体は、メタクリル酸メチル由来の繰り返し単位(以下、「メタクリル酸メチル単位」ともいう。)を含有する重合体である。本発明におけるメタクリル系樹脂組成物は、メタクリル系重合体を含有することにより、得られる樹脂成形体の色調が向上するとともに、樹脂成形体の熱分解が抑制され、色調、成形性を良好にすることができる。また、メタクリル系重合体は、メタクリル酸メチル単位を主成分とする重合体であることが好ましい。一態様として、「メタクリル酸メチル単位を主成分とする」とは、一態様として、メタクリル系重合体(100質量%)中のメタクリル酸メチル単位の含有割合が70質量%以上であることをいう。メタクリル系重合体(100質量%)中のメタクリル酸メチル単位の含有割合は、80質量%以上がより好ましく、90質量%以上がさらに好ましい。
これらの(メタ)アクリル酸エステルは、1種を単独で用いてもよく、2種以上を併用してもよい。
本発明におけるメタクリル系樹脂ペレットには、通常、メタクリル系樹脂ペレットに内添される各種の添加剤の1種又は2種以上が、本発明の効果を損なわない範囲で含まれていてもよい。

脂肪酸は、分子内にカルボキシル基を少なくとも1個有する鎖状炭化水素化合物である。分子内にカルボキシル基を少なくとも1個有する鎖状炭化水素化合物とは、カルボキシル基が結合する炭素原子が炭素鎖の構成原子となっている化合物を意味する。分子内にカルボキシル基を少なくとも1個有する鎖状炭化水素化合物中の炭素鎖は、飽和であっても不飽和であってもよく、また、直鎖状であっても分枝鎖状であってもよい。前記脂肪酸の中でも、直鎖状炭化水素化合物が好ましい。
上記の脂肪酸の融点の好ましい上限及び下限は任意に組み合わせることができる。例えば、脂肪酸の融点は、50℃以上100℃以下が好ましく、55℃以上90℃以下がより好ましく、60℃以上80℃以下がさらに好ましい。
炭素数8~22の飽和脂肪酸としては、例えば、カプリル酸(炭素数8)、ペラルゴン酸(炭素数9)、カプリン酸(炭素数10)、ラウリン酸(炭素数12)、ミリスチン酸(炭素数14)、ペンタデシル酸(炭素数15)、パルミチン酸(炭素数16)、マルガリン酸(炭素数17)、ステアリン酸(炭素数18)、アラキジン酸(炭素数20)、ヘンイコシル酸(炭素数21)、ベヘン酸(炭素数22)が挙げられる。
本発明におけるメタクリル系樹脂ペレットに脂肪酸を外添させて、本発明のメタクリル系樹脂成形材料を製造する方法としては、特に制限はない。前記の製造方法としては、例えば、ドライブレンドする方法や、撹拌装置を用いて、本発明におけるメタクリル系樹脂ペレットに脂肪酸を噴霧または粉体を添加して撹拌する方法や、脂肪酸を含有する液中にメタクリル系樹脂ペレットを分散させ、その後、メタクリル系樹脂ペレットの表面の溶剤を除去する方法が挙げられる。
噴霧手段としては、例えば、脂肪酸を噴霧するスプレーノズル等が挙げられる。噴霧手段は、脂肪酸を加熱するためのヒーター等の加熱手段を有していてもよい。
次いで、脂肪酸が噴霧、添着されたメタクリル系樹脂ペレットは、容器の内側壁面に沿って自転および公転するスクリューによって更に均一に撹拌される。これにより、メタクリル系樹脂ペレットに脂肪酸を均一に外添させることができる。
容器内の温度を変化させる方法としては、例えば、容器内に加熱した不活性ガスを流通させる方法、ヒーターで容器内を加熱する方法、容器のジャケットに熱媒などを流通させて温度制御する方法等が挙げられる。
本発明の樹脂成形体は、本発明のメタクリル系樹脂成形材料を成形してなるものである。
本発明の樹脂成形体は、公知の成形方法、例えば、プレス成形、射出成形、ガスアシスト射出成形、溶着成形、押出成形、吹込成形、フィルム成形、中空成形、多層成形、溶融紡糸によって成形されるものであれば、特に限定されない。本発明のメタクリル系樹脂成形材料は、優れた可塑化特性を得られる観点から、プレス成形、押出成形、射出成形またはフィルム成形用メタクリル系樹脂成形材料が好ましく、プレス成形、押出成形または射出成形用メタクリル系樹脂成形材料がより好ましく、押出成形または射出成形用メタクリル系樹脂成形材料がさらに好ましく、射出成形用メタクリル系樹脂成形材料が最も好適である。
