Abstract

The invention discloses a high insulating anticorrosive paint, which is designed for solving the technical problem that the comprehensive indexes of temperature resistance, flame resistance, heat insulation, adhesive force, density and the like of the conventional insulating patient are difficult to meet the harsh requirements of the high-speed train field. The paint comprises the following components in percentage by mass: 50 to 70 percent of epoxy modified organic silicon resin, 10 to 20 percent of hollow microspheres, 10 to 15 percent of composite flame retardant, 5 to 15 percent of hydrotalcite, 3 to 8 percent of titanium dioxide and 1 to 3 percent of auxiliary agent. The paint is prepared according to the proportion and requirements. The paint has the advantages that: the preparation process is simple, reasonable and easy to implement; the paint has good heat resistance, heat insulation, anticorrosive performance and heat preservation performance; and the paint is particularly suitable to be applied on high-speed trains and various aviation aircrafts with high comprehensive performance requirements.

Description

Technical field: [0001] The invention relates to a thermal insulation coating, in particular to a high thermal insulation anticorrosion coating. The coating is mainly used for heat insulation and anticorrosion of high-speed trains, and can also be used for heat insulation and anticorrosion of automobile engines, heat insulation and anticorrosion of high-temperature transportation pipelines in iron and steel enterprises, and heat insulation and anticorrosion of steel structure workshops. Background technique: [0002] With the development of high-speed railways, the running speed of trains is constantly increasing, and the power of train power plants is constantly increasing, resulting in continuous increase in the thermal load in the operating cabin, and the maximum temperature can reach 500°C. If no thermal protection is given, the engine and various The normal work of various accessories and auxiliary equipment, especially the current high-speed trains use various advanced...
