Abstract
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.
