Description
Technical field
The present invention relates to a kind of preparation methods of high tenacity heat-resisting mica tape by force, belong to electrical insulating material technology of preparing neck
Domain.
Background technique
Modern large-scale and medium-sized high-pressure electrical machinery technology development, proposes higher and higher want to the insulation performance of motor
It asks.Motor operating temperature, rated power, capacitance and volume all dramatically increase, and insulation system is subjected to higher electric stress, machine
Tool stress, thermal stress and environmental stress, motor working environment is further severe, preferably insulate this requires insulating materials has,
Heat-resisting, excellent wear-resisting property and enough intensity.
Mica tape, also known as fire-resistant isinglass belt are a kind of high performance mica insulation products.Mainly by mica paper, reinforcing material
Material, adhesive and other additives composition are passed through by adhesive bond mica paper, plastic film or alkali-free glass cloth reinforcement
The dribbling shape refractory insulating material that processes are process such as bake and bank up with earth, wind and cut, be often used as motor and cable insulation and
Flame retardant coating.It can be divided by purposes: motor mica tape, cable mica tape.It is divided by structure: double-sides belt, one-side band, three-in-one
Band, double film strips, monofilm band etc..It can be divided into again by mica: synthetic mica tape, gold mica tape, muscovite band.Because of its excellent resistance to height
Warm nature energy, flame resistance energy and proof voltage energy, are usually used in fire-resistant wire and cable.Mica tape is motor, especially large-scale, high
Medium-voltage Motor, wind-driven generator, the most key insulating materials irreplaceable in large-size variable-frequency variable-speed motor.

Powder, breakdown voltage are smaller, dielectric loss is higher, lead to that motor feels hot is big, loss of properties on aging, poor flame retardant properties, it is difficult to be applied to
The flame-resistant insulation of motor.
The power when comprehensive performance of existing mica tape is also possible that but generally existing thermal coefficient is relatively low, temperature is more than 100 DEG C
The disadvantages of learning performance poor (such as: bending strength at 100 DEG C only has 20~30MPa).In addition, using prior art production
Mica tape is filled with the gap between mica sheet due to a large amount of infiltrations of adhesive in mica paper, leads to the ventilative of low resin mica tape
Degree decline.In VPI treatment process, the rapid osmotic of impregnating resin is influenced, is occurred inside the insulation system for being easy to cause VPI to handle
Air gap and hair are empty, will generate shelf depreciation in motor operation course, directly affect the reliability and service life of motor.
Therefore, developing a kind of mica tape for being able to solve above-mentioned performance issue is highly desirable.
