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 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, its store usage period long, hot setting is fast, viscosity is low, and cohesive strength height, resistance toheat are 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 polyester resin, Resins, epoxy, tung oil acid anhydride, vinylbenzene, and wherein the weight percent content of each component is: unsaturated polyester resin 40-65%, Resins, epoxy 10-25%, tung oil acid anhydride 10-25%, vinylbenzene 12-35%.
It also comprises initiator, stopper and initiation promotor, and the weight percent of initiator is 0.1-2.0%, and the weight percent of stopper is 0.1-1.0%, and the weight percent that causes promotor is 0.05-0.50%.
Initiator is a dicumyl peroxide.
Stopper is a Resorcinol.
Initiation promotor is cobalt naphthenate.
Unsaturated polyester resin is the m-phthalic acid unsaturated polyester resin.
The present invention compared with prior art has the following advantages: the present invention has excellent in storage stability and impregnation technology, and its good heat resistance, cohesive force is strong, electrical insulation properties 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 polyester resin, Resins, epoxy, tung oil acid anhydride, vinylbenzene, and wherein the weight percent content of each component is: unsaturated polyester resin 50%, Resins, epoxy 12%, tung oil acid anhydride 12%, vinylbenzene 25%.
It also comprises initiator, stopper and initiation promotor, and the weight percent of initiator is 0.15%, and the weight percent of stopper is 0.55%, and the weight percent that causes promotor is 0.3%.
Initiator is a dicumyl peroxide, and its molecular formula is C

4(OH)
2, molecular structural formula is as follows:
Adopt Resorcinol as stopper, when unsaturated polyester is preserved, can absorb the peroxidation radical, thereby make stable resin, unlikely polymerization gelling.
Initiation promotor is cobalt naphthenate, and its molecular formula is [C
6H
9O
2(CH
