Description
Technical field
The present invention relates to enameled wire field of material technology, and in particular to a kind of property surely weather-proof high insulating property wire enamel and
Preparation method.
Background technology
Enameled wire is most representative product in electronic wire, and enameled wire is a principal item of winding wire, including
Core wire and coated in the enamelled coating on the outside of core wire after the annealed softening of bare wire, using multiple japanning, bakes, has machinery
Performance, chemical property, electrical property, four big performance of hot property.Copper-in-aluminum enameled wire and copper cladding aluminium-magnesium enamelled wire are to use copper-clad
Aluminium or aluminium in copper magnesium material make the novel electromagnetic wire of inner wire, and characteristic combines the good electric conductivity of copper between copper aluminium
With the light-weight advantage of aluminium, therefore have on transformer, high frequency winding, miniature motor rotor coil, various electromagnetic wires wide
General application.At present by types of conductors point, enameled wire has copper enameled wire, aluminium enamel-covered wire, copper-in-aluminum enameled wire etc., regardless of paint
Envelope curve all must make insulating layer with wire enamel.
Especially in high-power transformer, due to being usually connected with stronger electric current, and the environment ratio in internal winding
It is relatively severe, there is higher requirement to the performance of the wire enamel of coated wire.The transposed conductor that common self-adhesion paint coats at present
In 100 DEG C or more long-term works, the self-adhesion paint as adhesive between transposed conductor stock will appear softening, cause winding machinery strong
Degree declines；In 120 DEG C or more long-term works, self-adhesion paint can soften completely, and winding mechanical strength is nearly identical to non-self-adhesion and changes
Position conducting wire.Above-mentioned temperature condition does exist in power transformer actual motion, therefore it is required that self-adhesion paint and its coating
Transposed conductor must improve temperature capacity.Heat resistance self-adhesive paint is used in the production process of transposed conductor, can effectively improve transposition
The flexural rigidity of conducting wire under the high temperature conditions, and then improve mechanical strength of the transformer winding in the case where providing high temperature.But it is common
Wire enamel there are heat resistance, wear no resistance, insufficient strength, resistance to thermal level be less than 120 DEG C the problems such as, it is difficult to meet varying environment
Requirement.It needs to be improved the formula of wire enamel with production technology, further increases the performance of enamel-cover paint, reduce its life
Produce cost.
On the other hand, in the prior art, wire enamel wears no resistance, and the service life is low, is easy paint, and it is impossible to meet use to want
It asks.
Invention content
In view of the drawbacks of the prior art, the object of the present invention is to provide a kind of steady weather-proof high insulating property wire enamel of property,
Drying is very fast when the wire enamel uses, good leveling property, there is good tolerance, acid and alkali-resistance environment, performance to stablize high temperature
With lower water absorption rate and good mechanics and insulation performance, dielectric loss knee of curve temperature is higher, and mixes, sinks
Shallow lake, paint solution viscosity index are superior, while its cost of material is relatively low, and preparation process is concise, and application method is efficient and convenient, have higher
Practical value and good application prospect.
The present invention solves technical problem and adopts the following technical scheme that：
The present invention provides a kind of steady weather-proof high insulating property wire enamels of property, include the raw material of following parts by weight：
