本発明の(メタ)アクリル樹脂組成物に含有される化合物(X)は、炭化水素、脂肪酸、脂肪族アルコール、脂肪酸エステル、脂肪酸アミド、及び金属石鹸からなる群から選択される少なくとも1種以上の化合物である。 <Compound (X)>
Compound (X) contained in the (meth) acrylic resin composition of the present invention is at least one selected from the group consisting of hydrocarbons, fatty acids, aliphatic alcohols, fatty acid esters, fatty acid amides, and metal soaps. A compound.
(メタ)アクリル樹脂組成物の耐熱性が高いと熱融着にかかわる問題が生じにくいため好ましい。耐熱性の指標としては、例えば、ビカット軟化温度(JIS K7206またはISO 306(B50)で規定される)が挙げられる。 <Heat resistance of acrylic sheet>
It is preferable that the (meth) acrylic resin composition has high heat resistance because problems relating to heat fusion hardly occur. Examples of the heat resistance index include Vicat softening temperature (defined by JIS K7206 or ISO 306 (B50)).
90℃より低いと熱融着にかかわる問題が生じやすい。120℃より高いと、(メタ)アクリル樹脂組成物が脆くなる傾向があり、工具による加工の際、欠けやひび割れなどの外観品質の低下が生じやすい。 The Vicat softening temperature of the (meth) acrylic resin composition used in this embodiment is preferably in the range of 90 to 120 ° C., more preferably in the range of 95 to 115 ° C., still more preferably in the range of 100 to 115 ° C., and 101 to A range of 110 ° C. is more preferable.
When the temperature is lower than 90 ° C., problems relating to heat fusion are likely to occur. When the temperature is higher than 120 ° C., the (meth) acrylic resin composition tends to be brittle, and the appearance quality such as chipping and cracking tends to be deteriorated during processing with a tool.
(メタ)アクリル樹脂組成物は、(メタ)アクリル樹脂を重合した後、該樹脂を加熱溶融して化合物(X)を混練する溶融混練法によって製造してもよい。また(メタ)アクリル樹脂を重合する工程において重合性単量体と化合物(X)とを混合した後重合して製造してもよい。また重合工程において化合物(X)を加えた後、同一種または異種の化合物(X)をさらに溶融混練法によって加えて製造してもよい。 <Manufacture of (meth) acrylic resin composition>

Moreover, you may superpose | polymerize and manufacture after mixing a polymerizable monomer and compound (X) in the process of superposing | polymerizing a (meth) acrylic resin. Further, after adding the compound (X) in the polymerization step, the same or different compound (X) may be further added by a melt-kneading method.
以下、本実施形態のアクリルシートの特性、及びアクリルシートに適した(メタ)アクリル樹脂組成物の物性を示す。本実施形態のアクリルシートは、端面を切削加工したときのJIS B 0601(2001)の条件で測定した算術平均粗さRaが0.1~2.4μmの範囲であることが好ましい。 [Acrylic sheet embodiment]
Hereinafter, the properties of the acrylic sheet of the present embodiment and the physical properties of the (meth) acrylic resin composition suitable for the acrylic sheet are shown. In the acrylic sheet of the present embodiment, the arithmetic average roughness Ra measured under the conditions of JIS B 0601 (2001) when the end face is cut is preferably in the range of 0.1 to 2.4 μm.
本発明のアクリルシートは通常の成形方法で製造することができる。例えばセルキャスト法、射出成形法、押出成形法を採用でき、なかでも連続的に成形できる押出成形法が生産性の点で好ましい。 <Manufacture of acrylic sheet>
The acrylic sheet of the present invention can be produced by a normal molding method. For example, a cell casting method, an injection molding method, and an extrusion molding method can be adopted, and an extrusion molding method capable of continuous molding is particularly preferable in terms of productivity.
本実施形態のアクリルシートの厚さは0.5~20mmの範囲が好ましい。0.5mmより薄い場合、アクリルシートが割れやすくなり、取り扱い性が劣る場合がある。20mmより厚い場合、アクリルシートの加工において、工具とアクリルシートとの摩擦熱がアクリルシート内部に蓄積されやすくなるため、特に穴あけ加工において高温になりやすく、(メタ)アクリル樹脂の工具への融着及びアクリルシートの外観品質の低下の抑制が困難となる傾向がある。 <Thickness of acrylic sheet>
The thickness of the acrylic sheet of this embodiment is preferably in the range of 0.5 to 20 mm. When it is thinner than 0.5 mm, the acrylic sheet is likely to break, and the handleability may be inferior. When it is thicker than 20 mm, the frictional heat between the tool and the acrylic sheet tends to accumulate inside the acrylic sheet during the processing of the acrylic sheet, so it tends to become a high temperature, especially during drilling, and the (meth) acrylic resin is fused to the tool. And there exists a tendency for suppression of the fall of the external appearance quality of an acrylic sheet to become difficult.
本実施形態のアクリルシートはその表面が平滑であってもよいし、凹凸形状が成形されていてもよい。凹凸形状が成形される面は一方の面のみであってもよいし、両方の面であってもよい。凹凸形状としては、例えばレンチキュラーレンズや半球状レンズ、角錐状レンズなどが挙げられる。 <Shape of acrylic sheet>
The acrylic sheet of this embodiment may have a smooth surface or may have an uneven shape. Only one surface may be sufficient as the surface where an uneven | corrugated shape is shape | molded, and both surfaces may be sufficient as it. Examples of the concavo-convex shape include a lenticular lens, a hemispherical lens, and a pyramidal lens.

The measurement was performed at 10 locations for every 1 m in the extrusion flow direction. The difference between the maximum and minimum measured values was evaluated as thickness unevenness.
