Problems solved by technology

Among synthetic rubbers, silicone rubber has relatively excellent properties. It has a small thermal effect during vulcanization, can maintain elasticity for a long time in a wide temperature range, and also has good electrical insulation, oxygen resistance and aging resistance, and light resistance and aging resistance. properties, mildew resistance and chemical stability, so it has been widely used in the fields of electronics and electricity, but as a polymer material, its thermal conductivity is not very good, so the high temperature resistance of the motor slot wedge made of it is still not good. Very ideal, which greatly limits its application in some high temperature fields

Description

technical field [0001] The invention relates to the technical field of insulating materials, in particular to a high-temperature-resistant insulating material for motor slot wedges. Background technique [0002] Bamboo is a commonly used material for existing motor slot wedges. Because bamboo has the defects of poor heat resistance and flame retardancy, the motor slot wedges made of it have defects of not very ideal heat resistance and flame retardancy. In order to meet the needs of motor slot wedges for motors of various types and insulation levels, people continue to develop various new insulating materials for making motor slot wedges. Synthetic rubber in polymers is an indispensable and important material in insulating materials. Among synthetic rubbers, silicone rubber has relatively excellent properties. It has a small thermal effect during vulcanization, can maintain elasticity for a long time in a wide temperature range, and also has good electrical insulation, oxyge...
