Description
Technical field
The present invention relates to a kind of epoxy resin that is used for the electronics rotor, relate in particular to a kind of thermal conductivity epoxy impregnation glue, with increase high-temperature electric machine rotor product thermal conductivity, and the method for preparing this kind epoxy impregnation resin.
Background technology
In electric manufacturing, except that the motor global design that holds water, and require corresponding high performance insulating material to guarantee, must possess the certain process means simultaneously and just can be achieved; As: 1) rotating speed is 30; 000-50,000 rev/min high-speed electric expreess locomotive, the rotor winding under running up; Must prevent under strong action of centrifugal force and scatter, and need firmly bonding; 2) to bear torsion bigger for the direct connection gear box of motor shaft, and motor rotation requires intermittently to open and close; 3) during the high rotating speed of motor, rotor tip winding and end banding surface do not allow hole and blind hole, require surface smoothing, otherwise will in operation process, increase the noise of motor; 4) motor temperature rises to more than 150 ℃, and the insulation temperature classification requires in H level (180 ℃) or higher, adopts the process method of traditional insullac dipping, is difficult to reach requirement.
Because the thermal value of automobile current generator is high, and be applied to many dirt, make moist and high vibrations than severe environment, its reliability requirement is high especially.This also requires the solvent impregnated resin of motor to possess excellent heat-resistant aging, globality and physical strength.The high-performance special epoxy-resin systems that internationally famous car electrics manufacturers such as Bosch, Hitachi mainly adopts all belongs to the trickle resin product.Though the high temperature resistance polyester series products has application, as: Britain Sterling 87PR-477TC etc., hot physical strength also can meet the demands, and globality, cohesiveness, protective and resistance to cracking are all not enough greatly, only limit in the miniature high-speed rotor, use.
