Background
The organic silicon resin has the advantages of high heat resistance, excellent electrical insulation performance, good weather resistance and the like, and has been widely applied in the insulation field. The common organic silicon impregnating resin is solvent impregnating resin which contains a large amount of organic solvent, is discharged into the atmosphere in the production and construction processes, pollutes the environment and threatens the human health. The solvent-free impregnating varnish meets national environmental protection policy and legal regulations, and has low VOC (VOC content is less than 1 percent) emission in the high-temperature baking and curing process.
Traditional rail transit resin is easy to crack and drop under severe working conditions. When the rail transit motor is impregnated with the traditional organic silicon resin, the rail transit motor has larger potential safety hazard due to the problem of cracking of the insulating paint, and the operation cost is greatly increased because the potential hazard is removed by periodically carrying out paint dipping or maintenance. The traditional organic silicon resin has crushing fracture in the cold and hot impact process, and a surface paint film of the insulating wire rod also has a large number of scale-shaped cracks when impacted under the above conditions, so that the impact force of high and low temperature cold and hot is poor.
