Abstract

The invention relates to a ceramic film coating for an indoor decorative curtain wall of an urban rail transit station. The ceramic film coating is prepared from the following raw materials in percentage by mass: 58-62% of a component A, 30-37% of a component B and the balance of a component C, wherein the component A is a mill base; the component B comprises siloxane, an auxiliary and a solvent; and the component C is an acid. The ultraviolet reflectivity of nano-silicon nitride is over 95% and the absorptivity for the infrared band is over 97%. For an appliance, the ceramic forming temperature is low, the dimensional stability is good, the mechanical strength is high, and the chemical corrosion resistance is good, and particularly the coating which has the characteristics of great high-temperature strength, self-lubricating effect and small coefficient of sliding friction can be applied to a ceramic wear-resistant composite plating on the surface of a metal and can play a role of resisting wear and solvent after being applied to a coating.

Description

【Technical field】 [0001] The invention relates to the technical field of decorative walls in traffic places, in particular to a porcelain film paint used for interior decorative curtain walls of urban rail transit stations. 【Background technique】 [0002] China's urban rail transit has entered a golden period of development. At present, most of the coatings used on the decorative curtain walls of subway locomotive stations in my country are fluorocarbon paints, which are organic coatings. Perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid are released during the production process. Ammonium (PFOA) and other substances are not only harmful to the health of construction and users, causing environmental pollution, but also have fire hazards. Because urban subways have the characteristics of large passenger flow and large number of people per unit area, once a fire breaks out, it is very easy to cause mass death and mass injury. Moreover, in the case of fire, the tem...
