A high-speed locomotive windshield and a preparation method therefor. Said windshield comprises an anti-reflection film layer (1), chemically toughened glass layers (21, 22), adhesive film layers (3) and an anti-splashing layer (4). The anti-reflection film layer (1) is coated on one side of a first chemically toughened glass layer (21). The adhesive film layer is adhered between the first chemically toughened glass layer (21) and a second chemically toughened glass layer (22). The anti-splashing layer (4) is disposed on the outer side of the second chemical toughened glass layer (22), and the adhesive film layer (3) is adhered therebetween. First electric heating assemblies (5) are also comprised, and the first electric heating assemblies are arranged in the adhesive film layer (3) in contact with the first chemical toughened glass layer (21). The preparation method for the high-speed locomotive windshield is: respectively manufacturing the anti-splashing layer (1), the adhesive film layer (3), the first chemically toughened glass layer (21) coated with the anti-reflection film layer (1) and the second chemical toughened glass layer (22), laminating each of said layers, putting the laminated components into a vacuum bag and vacuumizing, reacting for 1.5h-2.5h at a temperature of 125℃-130℃ temperature and at a pressure of 1Mpa-1.5Mpa, and then removing the vacuum bag. The windshield in the present invention can meet the high-speed and safety operating requirements of locomotives and can prevent frost from affecting the field of vision.
