Abstract
This invention discloses an insulation anti-corona multi-function film with talc super-fine particles as the primary material including the following components in terms of weight percentage: talc 50-100%, Al2O 0-50%, ZrO2 0-50%, SiC4 0-50%, WoC4 0-50%, and size of particles of the components is below 6000 mesh and the film is formed by spraying them onto a matrix with a supersonic flame spray system, in which, the flow of oxygen is 40-47L/min and flow of gas fuel is 34-44L/min. This invention provides a method for preparing the films.
Description
Technical field
The present invention relates to a kind of method for preparing the isolated coronaproof film, being specifically related to a kind of is the isolated coronaproof film and preparation method thereof of primary raw material preparation with the mica.
Background technology
Because mica has higher dielectric strength and bigger resistance, lower dielectric loss and arc resistant, anti-corona and not firing, the dielectric behavior that waterproof etc. are good, and quality is hard, the mechanical strength height, good elasticity and flexibility are arranged, the rapid variation of high temperature resistant and temperature, and have acidproof, the physical and chemical performance that alkali etc. are good and under the condition of high temperature, can keep above-mentioned good physical and chemical performance, thereby it is widely used in electronics as a kind of very important insulating material, motor, telecommunication, electrical equipment, aviation, traffic, instrument, metallurgical, building materials, industrial departments such as light industry, and national defence and sophisticated industry field.
In the prior art, the application of mica mainly contains three kinds of forms: 1. powder, and powder is normally used for preparing the mica coating, when the preparation coating, need to add organic substance as film forming agent, yet, organic introducing can make the performance of mica coating, particularly thermal stability be subjected to very big influence; 2. mica splitting, because the restriction of thickness, mica splitting is difficult to be applied to the film field; 3. mica tape and mica paper, though mica paper and mica tape can be accomplished the thickness less than 0.1mm, they separate with the matrix that needs are isolated, this has had a strong impact on their application.Therefore, though mica has numerous premium properties,, limited the application of mica coating because masking technique is backward relatively.
Summary of the invention
The object of the invention provides a kind of isolated coronaproof multifunction thin film and preparation method thereof, to overcome the above-mentioned defective of prior art, enlarges the range of application of mica.
For achieving the above object, the technical solution used in the present invention is: a kind of isolated coronaproof multifunction thin film is that primary raw material is made by the mica ultra-fine grain, and by weight percentage, it contains following component,
Mica 50～1 00%,
Aluminium oxide: 0～50%,
Zirconia: 0～50%,
Carborundum: 0～50%,
Tungsten carbide: 0～50%,
The granular size of above-mentioned solid constituent sprays on the matrix by the HVAF system and to form below 6000 orders.
The preparation method of above-mentioned isolated coronaproof multifunction thin film is, each component is mixed, and is ground to the following size of 6000 orders, and described each component is, by weight percentage, comprise,
Mica 50～100%,
Aluminium oxide: 0～50%,
Zirconia: 0～50%,
Carborundum: 0～50%,
Tungsten carbide: 0～50%,
Adopt supersonic flame spraying method to prepare film, in the described supersonic flame spraying method, the flow of oxygen is 40～47 liters/minute; The flow of gaseous fuel is 34～44 liters/minute.
Wherein, described gaseous fuel is selected from hydrogen, acetylene or propane.
Advantages such as supersonic flame spraying method is the new technology of field of thermal spray, and the high-speed flame air-flow that forms by oxygen and fuel gas quickens ejection with the raw material particle, forms coated film on matrix, and it has particle flying speed height, and coating quality is good.On " Arms Material scientific and engineering " magazine the 25th volume the 3rd phase 63-66 page or leaf, in " HVAF is theoretical to make progress with Study on Technology " literary composition, to the HVAF technology and should be used as introduction, it is mainly used in the coated with hard alloy coat.Application in the mica film preparation is an innovation part of the present invention.Wherein, the granularity of control of the flow velocity of gas and particle plays a key effect for the performance of the film that forms.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. the invention provides a kind of method for preparing the anticorona film of insulation fire prevention, by this method, can on matrix, directly form the anticorona inorganic thin film of insulation fire prevention; Because film is directly to form on matrix, so the film thickness that forms can be less than 0.1mm, this has solved the insoluble film thickness problem of general employing winding process.
2. because film of the present invention is a straight forming, so to the size of matrix, shape does not have special requirement, and is simple to operate, do not need subsequent technique yet; The film breakdown voltage height that the present invention obtains, when insulation thickness was 0.1mm, the puncture voltage of pure mica can reach 10kV; Because the used material of the present invention is the material that does not fire, so prepared film of the present invention has anti-fire action.
3. the present invention does not need to adopt organic substance, and the inorganic thin film of acquisition has thermal stability preferably.
