The invention has excellent storage stability and impregnation manufacturability, good heat resistance, strong cohesive force and good electrical insulation performance, and is suitable for the impregnation insulation of medium-sized and small-sized mica tapes.
Description
Technical field
The present invention relates to a kind of solvent-free impregnating resin, particularly relate to a kind of solvent-free impregnating resin that is used for vacuum pressure impregnation of high voltage motor.
Background technology
In the prior art, in high-voltage motor is made, generally adopting " many rubber mouldings pressure " technology, promptly is after coil is wrapped up with many rubber powders mica tape, to put into hot-die heating and pressurizing curing molding.Coil is embedded in the electric machine stator iron groove then, handle through varnished insulation again.This insulation system and technology, equipment and frock are simple, but coil die stamping is when taking a lot of work, and production efficiency is low, and coil manufacturing process is many, and the factor that influences mass of coil is also many.
Along with the high-voltage motor improvement of Manufacturing Technology, " few glue is whole to be soaked " technology progressively is used.So-called " few glue is whole to be soaked " technology be exactly coil with dry mica paper tape wrapped after, directly embed in the stator coring groove, with solvent-free impregnating resin one-piece stator is carried out vacuum pressure impregnation then and handle, resin fully is penetrated in the coil covering, form firm integral body through baked and cured again.Solvent-free impregnating resin is the critical material of " few glue whole soaks " technology, must have long, advantage such as high temperature solidifies soon, viscosity is low, cohesive strength is high, electromechanical properties and resistance toheat are good of the usage period of storage.The service requirements that existing solvent-free impregnating resin does not all reach vacuum pressure impregnation of high voltage motor in storage period, usage period, and resistance toheat is not good enough, and cohesive strength is not enough.
Summary of the invention
The object of the invention provides a kind of solvent-free impregnating resin for vacuum pressure impregnation of high voltage motor, and its storage usage period is long, high temperature solidifies soon, viscosity is low, cohesive strength is high, resistance toheat is good.
Technical scheme of the present invention is: a kind of solvent-free impregnating resin for vacuum pressure impregnation of high voltage motor, it comprises unsaturated epoxy ester resin, Resins, epoxy, resol, vinylbenzene, and wherein the weight percent content of each component is: unsaturated epoxy ester resin 10-40%, Resins, epoxy 15-35%, resol 3-8%, vinylbenzene 30-50%.
It also comprises initiator, stopper and curing catalyst, and the weight percent of initiator is 0.1-2.0%, and the weight percent of stopper is 0.01-0.10%, and the weight percent of curing catalyst is 0.2-2.0%.
Initiator is a dicumyl peroxide.
Stopper is a 2.
Curing catalyst is an aluminium acetylacetonate.
The present invention compared with prior art has the following advantages: the present invention has excellent in storage stability and impregnation technology, its good heat resistance, and cohesive force is strong, and electrical insulation properties is good, is applicable to middle glue, dry mica paper tape varnished insulation.
Embodiment
A kind of solvent-free impregnating resin for vacuum pressure impregnation of high voltage motor, it comprises unsaturated epoxy ester resin, Resins, epoxy, resol, vinylbenzene, and wherein the weight percent content of each component is: unsaturated epoxy ester resin 30%, Resins, epoxy 20%, resol 5%, vinylbenzene 44%.
It also comprises initiator, stopper and curing catalyst, and the weight percent of initiator is 0.15%, and the weight percent of stopper is 0.10%, and the weight percent of curing catalyst is 0.75%.
Initiator is a dicumyl peroxide, and its molecular formula is C

5, structural formula is as follows:
Dicumyl peroxide is an initiator, and when room temperature, performance is more stable, in the time of 130-150 ℃, can resolve into the peroxidation radical very soon, causes the unsaturated polyester crosslinking curing.
Stopper is a 2, and its molecular formula is C
6H
2(NO
2)
3OH, structural formula is as follows:
When unsaturated polyester was preserved, 2 can absorb the peroxidation radical, thereby made stable resin, unlikely polymerization gelling.
Curing catalyst is an aluminium acetylacetonate, and its molecular formula is (C
5H
7O
2)
3Al, structural formula is as follows:
Aluminium acetylacetonate is when room temperature, and performance is more stable, in the time of 130-150 ℃, can promote fast epoxy resin curing.
The present invention has excellent stable storage and impregnation technology, good heat resistance, bonding power is strong, electric Good insulation preformance, be applicable to large and medium-sized high-voltage motor vacuum pressure mass-impregnation and other motors, electrical equipment around The varnished insulation of group is processed, and particularly can satisfy " glue is whole less soaks " technology to the high request of resin property.
