Description
Technical field
The present invention relates to a kind of film-forming methods, and in particular to a kind of novel Inverter fed motor PI film manufacturing method.
Background technique
Polyimides (PI) refers to a kind of polymer material on main chain containing imide ring, is to have been carried out industry at present
The special high molecular material changed, has superior physical mechanical comprehensive performance, and excellent electrical and chemical stability is widely answered
For high-technology field.And Kapton is one of wherein earliest commodity while being the maximum one kind of dosage.This
Kind novel fire resistant organic polymer thin film is the current best film class insulating materials of performance and most expensive film material in the world
One of material, referred to as " gold film ".It is increasingly heavier that the excellent performance of Kapton plays it in numerous areas
The effect wanted.Kapton is together with carbon fiber, aramid fiber, it is considered to be restricts China's Development of Hi-Tech industry at present
Three big bottleneck key high molecular materials.
The disadvantages of polyimides (PI) is organic polymer, and corona resistance is not high limits it in high-voltage generator, high pressure
The application of the variable-frequency motor that motor, pulsewidth modulation are powered etc..Nano aluminium oxide is added in polymer as filler, is improving
While Polymeric dielectric performance, the thermal conductivity of material can be improved, thus is had a wide range of applications in insulating materials field, is aoxidized
The type and structure of object are to influence the key factor of material corona-resistance property, and structure nano-scale alumina electric property appropriate is good, leads
Hot coefficient is high, is doped in PI, can improve the corona-resistance property and dielectric properties of PI.
Currently, domestic Kapton is there is poor product quality, comprehensive performance is unstable, product fining degree not
Enough, the disadvantages of less varieties, its application is affected.The present invention provides a kind of manufacturing method of the Kapton of Inverter fed motor,
The Kapton produced has the characteristic of Inverter fed motor, can be applicable to multiple industries such as electrical, high-speed rail.
Summary of the invention
It is an object of that present invention to provide a kind of novel Inverter fed motor PI film manufacturing methods.
For a kind of novel Inverter fed motor PI film manufacturing method, the technical solution used in the present invention are as follows: a kind of novel resistance to
Corona PI film manufacturing method.Its specific manufacturing method is to take the method for solution mixing by required filler and diamines, dianhydride
It reacts resulting polyamic acid to be sufficiently mixed, polyamic acid after mixing is uniformly then coated on flat sheet using film applicator
On, then the polyimides carried out needed for imidization generates is put it into high temperature oven.Product is finally taken out to cool down into the water
It will can be prepared by required material after the Kapton removing on plate after half an hour.Preferably, used filler
For nano alumina particles.
Preferably, using the method for manufacture polyamic acid as diaminodiphenyl ether is first dissolved in dimethyl acetamide
In, it is then slow added into pyromellitic acid anhydride, the body when diaminodiphenyl ether is equal with pyromellitic acid anhydride molal quantity
It is that viscosity can quickly increase, stops that pyromellitic acid anhydride is added at this time.
Preferably, used solution mixing method, which refers to, first dissolves in dimethylacetamide solution for nano alumina particles
In, it is uniformly mixed, then it is mixed evenly with polyamic acid solution, vacuumizing bubble removing can be prepared by containing receiving
The polyamic acid solution of rice aluminium oxide.
Preferably, used flat sheet can be armorplate glass, film thickness can be 20 microns.
Preferably, the temperature that generation polyamic acid carries out imidization in high temperature oven starts to can be 80 DEG C of heat preservations
1H, then 100 DEG C, 150 DEG C, 200 DEG C, 250 DEG C, 300 DEG C respectively keep the temperature 30 minutes.
Possessed advantage is compared with prior art:
1: the present invention is dissolved in nano alumina particles in polyamic acid using solution mixing method, then carries out imidization again
Polyimides is produced, production method is simple, and nano particle is well dispersed in polyimides.
2: polyimides produced by the invention has the characteristic of Inverter fed motor, can be applicable to some special fields, such as high-speed rail
Equal fields.
Specific embodiment
Example description is carried out below in conjunction with method of the invention, the technical solution in present example is described,
Obviously, the example is only a part of example of the present invention, instead of all the embodiments.Based on the implementation in the present invention
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
Protection scope of the present invention.
Example 1: weighing 25g diaminodiphenyl ether, is dissolved in 200g dimethylacetamide solution, slowly adds while stirring
Enter in 31.6g pyromellitic acid anhydride, stirring is until solution viscosity becomes larger and rod climbing phenomenon occurs.Weigh 100g nano aluminium oxide
Grain, is dissolved in 150g dimethylacetamide solution, is after mixing evenly mixed it with polyamic acid solution, and 3H is stirred, and is taken out
Bubble is removed in vacuo.Aforesaid liquid is taken out and is uniformly coated in it on armorplate glass using automatic film applicator, applies film thickness
The armorplate glass for being covered with polyamic acid solution, is then put into high temperature oven by 20 microns of degree, controls heating and heat preservation speed, makes
It carries out imidization, and temperature regulation starts to can be 80 DEG C of heat preservation 1H, and then 100 DEG C, 150 DEG C, 200 DEG C, 250 DEG C, 300 DEG C each
Heat preservation 30 minutes.Finally equal oven temperatures, which reduce, takes out plate, cools down 30 minutes into the water, then polyimides above is thin
Film peels off the Kapton that can be prepared by having Inverter fed motor.
