Abstract

The invention relates to a ceramic membrane coating for an interior decorative plate of an urban rail transit vehicle. The ceramic membrane coating is characterized by comprising the following three raw material components in percentage by mass: 60-65 parts of a first component, 28-34% of a second component and the balance being a third component, wherein the first component is color paste, the second component comprises siloxane, and the third component is acid. The conventional ceramic membrane coating is of a double-coating structure comprising a base coating and a surface coating; generally speaking, the base coating has a color, mechanical performances and the like, and the surface coating has a using function, luster and the like. The coating disclosed by the invention is of a single-coating structure and not only has the functionality, but also has the luster and color; nanometer silicon boride has the characteristics of oxidation resistance, heat shock resistance, chemical erosion resistance and the like and particularly has the very high strength and stability under shock; and by using the ceramic membrane coating, the carriage matrix of a locomotive can be protected, the service cycle of the ceramic membrane coating can be prolonged, and the service life of the ceramic membrane coating can be prolonged.
