The invention relates to a high-performance rubber outer windshield for a high-speed rail motor train unit. A production flow of the high-performance rubber outer windshield comprises the following steps: rubber main body preformation, rubber coating, dynamic vulcanization formation, surface processing and paint spraying. By utilizing a coating process, the contact area between the surface of the outer windshield and paint is improved, and the adhesive property between the surface of the outer windshield and the paint is increased. For obtaining the high-performance rubber outer windshield, the application further develops an outer windshield product in which a cloth film is not adopted, and an inorganic cloth film woven by using modified SiC is adopted. The high-performance rubber outer windshield has the beneficial effects that on one hand, the outer windshield is well compounded with a rubber system, so that the strength, oxygen resistance and high temperature resistance of the surface of the outer windshield are improved; and on the other hand, the outer windshield participates in the curing of the paint, so that the adhesion force between the paint and a rubber matrix is remarkably increased.
