Problems solved by technology

[0003] At present, the sun protection and rain protection measures for the boxcar wallboard mainly adopt the method of applying paint on the outer layer, but with the prolongation of use time, the paint peels off, and its rain and sun protection effect is obviously affected. If it is not maintained, it will cause corrosion damage to the internal materials , shorten its service life and increase more maintenance costs

Abstract

The invention discloses a wallboard for boxcars, which is a laminar composite material. A metal ceramic composite coating is sprayed on the external surface of an aluminum honeycomb substrate, and a high-polymer coating is arranged on the external surface of the metal ceramic composite coating. Iron powder and ZrO2 powder in the metal ceramic composite powder generate an amorphous phase, thereby enhancing the bonding property with the aluminum cellular board, and enhancing the strength and hardness of the coating. The high-polymer coating is arranged on the external surface of the metal ceramic composite coating by dipping or brushing; and the anticorrosive component and sun protection component contained in the high-polymer coating enhance the corrosion resistance of the coating under the synergistic actions of other components. The added hypophosphorous acid aluminum powder is wrapped as an inorganic phase by various components in the high-polymer paint, thereby performing the synergistic function. The sun protection component is added into the high-polymer coating in a composite wrapping mode to perform the synergistic function. The wallboard can avoid peeling, and has longer service life.

Description

technical field [0001] The invention relates to an accessory for a rail transportation vehicle, in particular to a wall panel for a box car. Background technique [0002] A boxcar is composed of side walls, end walls, floor and roof, and is a railway wagon with sliding doors and ventilation windows on the side walls. It is used to ship valuable and goods that are afraid of the sun and rain. Some install stoves, chimneys, bed boards, etc. in the car, and can transport people and livestock when necessary. As one of the important components of the boxcar, the side wall panel is not only required to have good load-bearing, but also required to have good rainproof, sunscreen, corrosion resistance and other properties due to long-term use. [0003] At present, the sun protection and rain protection measures for the boxcar wallboard mainly adopt the method of applying paint on the outer layer, but with the prolongation of use time, the paint peels off, and its rain and sun protec...
