The invention relates to a composite front windshield glass for a high-speed locomotive and a preparation method thereof, the composite front windshield glass for the high-speed locomotive comprises an anti-splashing layer, an electric heating assembly, a plurality of ultra-strong chemical glass layers and bonding layers, and at least one bonding layer is a PVB/high-modulus K2O.nS < i > O2-based nano soft fiber/PVB interpenetrating network film. The flame-retardant PVB rubber sheet for the high-speed locomotive overcomes the defect that a PVB rubber sheet for the high-speed locomotive in the prior art cannot resist flame in sudden fire, and avoids the defects that a PVB rubber layer is inflammable, bubbles, poor in impact strength and the like.
本发明是关于一种高速机车用复合式前风挡玻璃及其制备方法,其中,高速机车用复合式前风挡玻璃包括防飞溅层、电热组件、若干个超强化学玻璃层以及粘接层,至少有一个所述粘接层为PVB/高模数K2O·nS iO2基纳米软质纤维/PVB互穿网络胶片。本发明克服了现有技术中高速机车用PVB胶片在突发火情中无法阻燃的弊端,避免了PVB胶层易燃、出泡、抗冲击强度差等缺点。
