Description
Technical field
The invention discloses a kind of compound lamination coating, belong to technical field of coatings.
Background technology
Silicon steel sheet is the important component of machine field, and lamination coating is then the predominating insulation of silicon steel sheet, silicon steel
The performance of piece paint directly affects the application of silicon steel sheet.In recent years, as people's environmental consciousness is further lifted, water-soluble silicon steel disc
Paint the focus to study and applying.
Lamination coating is a kind of insulating materials for high voltage motor stator iron core, and it decides the performance of stator core.
It is increasing to the demand of large-size machine with the continuous development of electric utility, pass of the lamination coating as motor electrical insulation system
One of key material, to its performance requirement also more and more higher.Traditional lamination coating product be all using organic reagent as solvent, it is organic
Solvent is volatile in the production and use process, jeopardizes the health of producers and causes environmental pollution.
Silicon steel sheet occupies critical role in magnetic material, is mainly used as the iron core of electric rotating machine, it is necessary in silicon steel sheet
Surface coats dielectric film, increases eddy-current loss to prevent from short circuit occurs between core lamination stack, improves its electromagnetic performance.Lamination coating
Just it is being increasingly subject to praise highly energetically as a kind of insulated paint for improving material property.With the continuous increase of motor single-machine capacity and electricity
The raising of the temperature classification of mechanical, electrical device, higher and higher requirement is proposed insulation stator iron core silicon steel sheet.Ordinary circumstance
Under, it is easily caused when electric motor starting or when breaking down that temperature is too high, iron core is short-circuit.In addition, in some special application scenarios, apply
Layer needs to be heat-treated by 600 DEG C of techniques, insulating coating could be used as to use.But under 600 DEG C of high temperature, in organic coating
The most of volatilization of having degraded of resin, loses good adhesive force and insulating capacity.Common high-temperaure coating is in high temperature（It is more than
300℃）It can be to some extent carbonized in environment and cause the decay of coating performance, especially " heat is shaken "（From specified high temperature wink
Between be reduced to repeating for normal temperature, it is general to require to be more than 10 times）When coating can ftracture, come off, it is difficult to meet actual demand.And
Ceramic type coating（Silicates coating）Although high temperature resistant（Resistance to more than 1000 DEG C of high temperature）, but wanting for " heat being shaken " can not be adapted to
Ask.Inorganic and half inorganic coating is all used in motor stator core silicon steel sheet insulating technical elements at present, and with people's environmental protection
The enhancing of consciousness, the safety that organic solvent caused by traditional lamination coating containing organic substance volatilizees and brought are asked with pollution
Topic also gradually shows.Nontoxic, of low pollution substitute turns into the direction that researcher finds.Therefore, develop a kind of advanced in performance
And the lamination coating of environmental protection, it is particularly significant.
