Background

Electrostatic spinning is one of the simplest and most efficient methods for preparing polymer nanofibers at present, and is widely concerned at home and abroad due to the advantages of simple device, wide raw material source, low cost and the like. The principle of the electrostatic spinning technology is very simple, the conductive metal needle point of the injector filled with the polymer concentrated solution or the melt is connected with the positive pole of the high-voltage generator, and a grounded metal flat plate is used as a receiving device. High voltage static electricity is added on the needle point, the suspended charged liquid drop is stretched to form a Taylor cone under the action of electric field force (the Taylor cone is that the solution is in a liquid storage tube, the liquid drop suspended at a tube opening is formed under the action of the adhesive force of the solution and the tube wall, the viscosity and the surface tension of the solution, the surface of the liquid drop is full of charges under the action of the electric field force, the Coulomb force between the charges is opposite to the surface tension of the liquid drop, the liquid drop is gradually elongated along with the increase of the electric field force, and when the value of the applied electric field force is equal to the surface tension of the liquid drop, the liquid drop forms a cone with the apex angle of 49.3 degrees and. When the electric field force can overcome the surface tension of the polymer liquid drop, the surface of the polymer liquid drop starts to form a jet trickle, the solvent is evaporated or solidified in the jetting process of the trickle, and finally, the solidified micro-nano fiber is obtained on the collecting plate.

In the whole electrostatic spinning process, the heating of the polymer is an important step, and in the prior art, when the high-voltage electrostatic melt spinning is realized, a terminal of high voltage electricity is mostly connected with a nozzle end, and then an electric heating wire is wound on a charging barrel to heat the charging barrel. And because the voltage of the high-tension electricity of nozzle end connection is about 5 ~ 50KV usually, and the voltage that the heating wire is connected is 220V usually, this kind of arrangement mode can make the heating wire on the feed cylinder very near apart from the high pressure of nozzle end, causes these two kinds of voltages to interfere with each other very easily, and then makes the components and parts on the spinning equipment puncture very easily, reduces the life of its device. Meanwhile, in the heating process by the electric heating wire, the heat transfer loss is high, so that the heating efficiency is not high.
