Abstract
Description
本発明は、塗料組成物及びフィルムに関する。 The present invention relates to coating compositions and films.
プラスチック基材の表面は比較的柔軟であり、その表面硬度が低いために取り扱う際に傷がつきやすい傾向にある。その傷を防ぐため、基材表面にハードコート膜を設けて表面硬度を高める方法が広く用いられている。また、ガラスのような比較的高硬度の基材においても、機能性の付与の観点で塗装処理が行われている。いずれにおいても、紫外線や電子線を用いて硬化させて塗膜を形成させる方法が主流であり、実施の際には特別な設備導入が必要なことから、限定的な環境下で製造される。一方、より汎用的な設備としては、例えばオーブンのような加熱設備があり、高いエネルギーが必要であるものの、汎用性が高いため、熱硬化によるコーティングの開発検討が進められている。 The surface of the plastic base material is relatively flexible, and its low surface hardness tends to cause scratches during handling. In order to prevent the scratches, a method of increasing the surface hardness by providing a hard coat film on the surface of the base material is widely used. Further, even a relatively high hardness base material such as glass is subjected to a coating treatment from the viewpoint of imparting functionality. In either case, the method of forming a coating film by curing using ultraviolet rays or electron beams is the mainstream, and since it is necessary to introduce special equipment at the time of implementation, it is manufactured in a limited environment. On the other hand, as a more general-purpose equipment, for example, there is a heating equipment such as an oven, which requires high energy, but is highly versatile, so development studies of a coating by thermosetting are underway.
熱硬化型による高硬度塗膜の作製方法としては、例えばポリイソシアネートにアルコキシシランを導入した特許文献1、2の方法が知られている。特許文献1では、ポリイソシアネートにアミノシランカップリング剤を反応させて得られた組成物に、特殊なアルミニウム触媒を添加し、ポリアクリルポリオールと混合して熱をかけることで耐引掻性の高い硬化性樹脂組成物を製造している。特許文献2では、ポリイソシアネートの一部にアミノシランカップリング剤を反応させ、ポリアクリルポリオールと混合することで硬化性樹脂組成物を作製しており、高い耐引掻き性を達成している。 As a method for producing a high-hardness coating film by a thermosetting type, for example, the methods of Patent Documents 1 and 2 in which alkoxysilane is introduced into polyisocyanate are known. In Patent Document 1, a special aluminum catalyst is added to a composition obtained by reacting a polyisocyanate with an aminosilane coupling agent, mixed with a polyacrylic polyol, and heat is applied to cure the composition with high scratch resistance. Manufactures sex resin compositions. In Patent Document 2, a curable resin composition is produced by reacting a part of polyisocyanate with an aminosilane coupling agent and mixing it with a polyacrylic polyol, achieving high scratch resistance.
特許文献1及び2に記載の硬化性樹脂組成物を得る上では高熱をかける条件が必須のため、加熱設備が必要となる。しかしながら、近年、塗装工程における更なる省エネルギー化が求められており、硬化性樹脂組成物を得る上でエネルギー効率の良い塗装方法が望まれてきている。 In order to obtain the curable resin compositions described in Patent Documents 1 and 2, conditions for applying high heat are indispensable, so a heating facility is required. However, in recent years, further energy saving in the coating process has been required, and an energy-efficient coating method has been desired in order to obtain a curable resin composition.
