Abstract

The invention discloses paint for a train body surface of a high speed train, which is prepared by preparing a matrix resin by mixing elastic polyester with high hydroxyl value and hydroxylated acrylic resin, using rutile type titanium dioxide as a pigment, using silicon-aluminum base ceramic cenosphere as a filler and using a nanometer ATO and a nanometer SiO2 as modified materials; preparing a component A by the processes of grinding, stirring, mixing, packaging and the like in the presence of an auxiliary and a solvent; and using HDI tripolymer N-3390 as a component B; and mixing the component A and the component B. The paint has the advantages of high adhesive force, high hardness, sand rock impact resistance, heat insulation, energy-saving, corrosion resistance, temperature change resistance, high weather resistance, easy cleaning, decorativeness, strong security and long service life, and is suitable for protective paint of the train body surface of the high speed train.

Description

[0001] Field of invention [0002] The invention relates to the technical field of metal surface coatings, in particular to a surface coating for high-speed train car bodies. Background technique [0003] As we all know, the development of the transportation industry reflects the degree of a country's modernization and progress, and occupies an important position in the national economy. In recent years, with the vigorous development of the transportation industry around the world, especially the rapid development of rail transportation has attracted worldwide attention. With the continuous improvement of the speed of high-speed trains and the popularization of intercity high-speed trains, it is bound to bring a series of technological revolutions to the development of high-speed trains. With the change of high-speed train body materials, such as the use of carbon steel to lightweight aluminum alloy or other aviation materials, the protective coating used on its surface will ...
