Description
Technical field
The invention discloses a kind of flame retardant type wire enamel, belong to technical field of coatings.
Background technology
With the raising of economy and living standards of the people, wire enamel is all increasing rapidly in military and people's livelihood field demand
It is long.The wire enamel on plain conductor surface forms insulating protective layer after high temperature bakees in wire surface, due to the technique system
Simplicity is made, insulation thickness is moderate, advantageous etc. in terms of shaping, is had a wide range of applications in fields such as electrician, electronics, electric appliances.Make
For a kind of excellent coating of electrical insulation capability, wire enamel is essential material in electrical equipment, its quality direct relation
To the economic and technical norms and service life of electrical equipment.Since electrical equipment and electrical is towards small, high-power trend development, and line
Circle can produce big heat in operation, therefore the temperature classification requirement to insulating materials is higher and higher, and nuclear power and universe
The development of space technology proposes winding wire harsher high temperature resistant requirement, meanwhile, the mechanization of winding and high speed process
It is required that winding wire has good surface property.Enameled wire is made of bare conductor and the insulation paint film two parts being coated on outside it,
By applying coil is coiled into after line dip-coating binding resin is bonded together each circle conducting wire again.Quality, the technique of wire enamel performance
The stabilization of the size of nargin and quality or not it can all directly affect the performance of enameled wire.In production of enamel wire process and motor
Can be produced in electric operation various complicated mechanical stresses such as rub, bend, stretching, compressing, impact stress, so paint
Film should have elasticity and pliability.In addition, paint film will also be amenable to thermal shocking and heat, electricity, mechanical stress under stress state
Synergy.Therefore, the stability after its film forming also becomes focus of attention.In addition, enameled wire is widely used in
In household electrical appliance, its security and people's daily life are closely bound up.Although fire incident occurs for many household electrical appliance
Completely as caused by enameled wire, but the material that household electrical appliances manufacturer uses it proposes non-ignitable or fire retardant requirement including enameled wire
The surface insulation processing mode of plain conductor generally has wrapped film, wrapped mica tape and surface coating insulated paint etc..
Therefore, it is the shortcomings that how improving traditional wire enamel fire resistance and bad film forming stability, comprehensive to obtain higher
The wire enamel of performance is closed, is that it is promoted and applies, meets industrial production demand urgent problem to be solved.
The content of the invention
The present invention solves the technical problem of:It is bad for traditional wire enamel fire resistance and film forming stability
A kind of shortcoming, there is provided flame retardant type wire enamel.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is:
