Abstract

The present invention discloses a UV-curing-based solvent-free electrostatic spinning apparatus. The apparatus comprises a high voltage power supply, a liquid storage mechanism, a spinning nozzle, an oxygen isolating mechanism, an ultraviolet light source and a collector; the anode of the high voltage power supply is connected with the spinning nozzle; the spinning nozzle is communicated with the liquid storage mechanism for storing spinning precursor solution; the collector is connected with the cathode of the high voltage power supply or directly grounded; the oxygen isolating mechanism comprises a sealing box, the inside of which is anoxic or mionectic; the spinning nozzle and the collector are positioned in the sealing box; the ultraviolet light source is positioned in the sealing box or ultraviolet light emitted by the ultraviolet light source can enters into the sealing box; and the ultraviolet light source can irradiate space between the spinning nozzle and the collector. The apparatus can be used for continuously preparing photo-curing material micro-nano fiber in batches. The apparatus is simple in operation and safe and environment-friendly, environmental pollution caused by organic solvent volatilization can be effectively avoided, and the apparatus is especially suitable for large-scale commercial production of the photo-curing material micro-nano fiber.

Description

Technical field

[0001] The invention relates to a solvent-free electrostatic spinning device based on UV curing. Background technique

[0002] Electrospinning technology is a simple and effective method for preparing micro / nano fibers. Not only can we prepare uniform and continuous one-dimensional fibers, but also micro / nano fibers with various morphology and structural characteristics. However, with the rapid development of nanotechnology, people are paying more and more attention to environmental protection and large-scale production. Traditional electrospinning generally requires the use of a large amount of organic solvents in the preparation of micro / nano fiber precursor solutions, and during electrospinning, more than 80% of the organic solvents are volatilized and difficult to recycle, causing pollution and making the solution electrospinning The industrialization of silk preparation of micro / nano fibers is limited.

[0003] In order to solve the problem of solvent volatil...
