Description
本発明はプラスチック及び高分子フィルム表面等に用いられる防曇剤組成物、及びその防曇剤組成物が塗布された合成樹脂に関する。 The present invention relates to an antifogging agent composition used for plastic and polymer film surfaces and the like, and a synthetic resin coated with the antifogging agent composition.
プラスチック、高分子フィルム等の表面は水滴の凝集或いは付着によって曇り易く、その本来の透明性が著しく損われ、或いは表面反射のむらを生じる。これらの曇りはその使用目的に応じて、種々の障害を引き起こす。例えばゴーグルの曇りは、使用上不便であり、運転上非常に危険性を伴う。またショーウインドウの曇りは、その本来の陳列効果を果さない。 Surfaces of plastics, polymer films, and the like are easily clouded by aggregation or adhesion of water droplets, and their original transparency is significantly impaired, or uneven surface reflection occurs. These hazes cause various obstacles depending on the purpose of use. For example, fogging of goggles is inconvenient to use and is extremely dangerous for driving. In addition, the cloudiness of the show window does not achieve its original display effect.
この様な曇りを防ぐ目的で従来から種々の防曇剤が提案されている。例えばソーダ石鹸、アルキルスルホン酸塩、ポリオキシアルキレンアルキルエーテル、ポリビニルアルコール、アルブミン分解物、ロート油、サポニン等の湿潤性の防曇剤は、表面に湿潤性の膜を形成させ、表面の自由エネルギーを大きくすることにより、水で一様に濡らし光の乱反射を防止するものである。又、ケイ素樹脂、ワックス、パインタール、アスファルト等を主剤とする撥水性の防曇剤が提案されている。これはガラス表面に凝集した水滴を速やかに表面から流去しようとするものである。 Conventionally, various antifogging agents have been proposed for the purpose of preventing such fogging. For example, wetting antifogging agents such as soda soap, alkyl sulfonates, polyoxyalkylene alkyl ethers, polyvinyl alcohol, albumin degradation products, funnel oil, saponins, etc., form a wettable film on the surface and free energy on the surface. By increasing the thickness, water is uniformly wetted to prevent irregular reflection of light. In addition, a water-repellent antifogging agent mainly composed of silicon resin, wax, pine tar, asphalt or the like has been proposed. This is intended to promptly remove water droplets aggregated on the glass surface from the surface.
湿潤性の防曇剤においても色々な問題点が未解決である。すなわち、一般に界面活性剤の湿潤性被膜は凝集水分によりアクリル樹脂板などの表面から流去し易く効果持続性の点でやはり問題がある。また、塗布した場合にいずれも湿潤性の塗布被膜が不透明不均一になるために、防曇剤自体によってアクリル樹脂板等の透視性が損なわれ、仕上り性がよくないといった欠点がある。更には、浸透した防曇剤により経時的に樹脂に割れが生じ、白化現象を起こし、見た目を損なうという事も起こり得るし、急激な気温変化により防曇剤が抽出、固化し、表面上に異物として存在する場合がある。更には、拭き取りに労力を要し、拭きムラによる白化現象が起き易い。 Various problems are still unsolved in wet antifogging agents. That is, in general, a wettable film of a surfactant has a problem in that it is easy to flow away from the surface of an acrylic resin plate or the like due to agglomerated moisture and the effect is sustained. In addition, since the wet coating film becomes opaque and non-uniform when applied, the antifogging agent itself impairs the transparency of the acrylic resin plate and the like, resulting in poor finish. Furthermore, the resin may crack over time due to the permeated anti-fogging agent, causing whitening phenomenon, and the appearance may be impaired, and the anti-fogging agent is extracted and solidified due to a sudden change in temperature. It may exist as a foreign object. Furthermore, wiping requires labor, and whitening due to uneven wiping easily occurs.
このような問題を解決しうる防曇剤の例として、特許文献１には、ポリビニルアルコールとシラン化合物を主成分とする防曇剤が提案されている。しかしながら、防曇効果の持続性が十分ではなく、更なる改善が望まれている。
