Description
technical field [0001] The invention relates to the technical field of insulating plastic materials, in particular to a composite insulating plastic material and a preparation method thereof. Background technique [0002] Insulating materials are non-conductive materials under the allowable voltage, but they are not absolutely non-conductive materials. Under the action of a certain applied electric field strength, processes such as conduction, polarization, loss, breakdown, etc. will also occur, and aging will occur after long-term use . Its resistivity is very high, usually in the range of 1010 ~ 1022Ω·m. As in an electric motor, the insulation around the conductors isolates the turns from each other and from the grounded stator core to ensure safe operation of the motor. [0003] The existing insulating plastic materials have low heat resistance and moisture resistance, low strength, poor insulation effect, poor stability, complicated processing technology, insufficient ...
