摘要

本研究中探討紫外光可硬化聚胺酯丙烯酸樹脂應用於玻璃基材之防護膜，使玻璃基材能於受撞擊破裂時也不會飛散開。經由比較不同二異氰酸酯、聚合多元醇以及不同設計結構了解各項變因如胺酯連結密度與交聯密度對樹脂熱性質、光學性質與機械性質的影響。
為了達到較佳的玻璃防護效果，樹脂必須擁有絕佳的玻璃黏著力與強韌的機械性質。可利用丙烯酸系矽氧烷化合物3-(甲基丙烯酰氧)丙基三甲氧基矽烷 (3-Methacryloxypropyltrimethoxysilane, MSMA )透過溶膠-凝膠法對玻璃進行改質，使其表面帶有具反應性之壓克力官能基，如此即可於光聚合反應中與聚胺酯丙烯酸樹脂進行形成化學鍵結增強黏著力。對於機械性質的補強有兩種方式，其一為利用高韌性聚胺酯混摻聚胺酯丙烯酸樹脂，使其聚合後形成半網狀互穿高分子結構，得到增韌效果。另一種方法為利用改變平均聚合軟鏈段分子量的形式調整交聯密度與胺酯連結密度，進而合成更加強韌的樹脂。IBp051kDUA樹脂在所合成之樹脂中展現出最好防護效果，能以200μm之厚度在耐撞擊測試中達到最佳測試等級，且塗佈於玻璃上之平均可見光穿透度接近90%。

In this study, a series of UV-curable urethane acrylate resin, applied as blast resistant film on the glass substrate were developed. This blast resistant film was designed to be able to stick the glass debris when the glass is broken. We could find the influences of structures with different urethane linkage and crosslink density on thermal, optical, and mechanical properties of urethane acrylate.
In order to reach better protective effect, the resin must have outstanding adhesion strength to glass and mechanical property. To improve the interaction between resin and glass, the 3-Methacryloxypropyltrimethoxysilane (MSMA) was used to modify glass surface through sol-gel process to form the chemical bonds with the urethane acrylate resins during the UV-curing process. Tensile property of urethane acrylate resin can be improved by blending high toughness PU to form semi-IPNs structure. In other way, we can design and synthesis the resin which has proper density of urethane linkage and crosslink point by changing average molecular weight of urethane acrylate monomer. IBp051kDUA exhibit the best protective effect in the blast-resistance test, and IBp051kDUA-coated glass has about 90% visible light transmittance.
