METHOD OF FORMING PROTECTIVE LAYER OF RAILWAY TRANSPORT BODY Russian patent published in 2017 - IPC B61D17/18 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to production of protective coatings, including heat insulation and noise-isolation, for vehicles. Method of formation of protective layer of body includes cleaning of surface, application to vehicle body of priming coating layer, to which noise-attenuating coating is applied. At least one heat-insulation layer is formed by applying heat insulating mastic in liquid state, made of composition containing polymer binder and hollow microspheres, wherein heat insulation layer has heat conductivity of no more than 0.003 W/m °C, density in range of 350–400 kg/m³. Heat insulation layer is formed of process layers, in amount from one to five. Each process layer has thickness of no more than 1,500 mcm and is formed by application of auxiliary layers in amount of no more than five. After application of each auxiliary layer it is dried and layer thickness is controlled.

EFFECT: invention improves technological effectiveness.
