Description
Technical field
The present invention relates to a kind of solvent-free electrostatic spinning apparatus based on UV solidification.
Background technology
Electrostatic spinning technique is as a kind of method simply effectively preparing micro/nano-fibre.Not only can prepare uniformly continous one dimension fibre, and prepare the micro/nano-fibre of various pattern and architectural feature, but developing rapidly along with nanometer technology, and people more and more pay attention to environmental protection and large-scale production.Conventional electrostatic spinning generally needs to use a large amount of organic solvent in the precursor solution preparing micro/nano-fibre, and when electrostatic spinning, have the organic solvent volatilization more than 80% and be difficult to reclaim, thus pollute, the industrialization making solution electrostatic spinning prepare micro/nano-fibre is restricted.
In order to solve solvent evaporates problem, no-solvent electrically is spun into as one of current study hotspot.The key of solvent-free electrostatic spinning is that spinning precursor solution can as the main body participation fibroblast of spinning fibre, and need to solidify fast while electrospinning.Chinese scholars has been done some and has been explored in solvent-free electrostatic spinning, at present, having of having reported utilizes the fast wet of a-cyanoacrylate (main components of medical adhesive, 502 glue) curing, and electrospinning becomes micro nanometer fiber (PolymerChemistry4:5696 (2013)); Chinese patent (patent publication No.: CN104532367A) discloses a kind of method that solvent-free electrostatic spinning prepares polyurethane micro nanometer fiber, mainly through heating collector, realizes solvent-free electrostatic spinning with the method for heat cure; Chinese patent (patent publication No.: CN104213207A) discloses a kind of packaged type air pressure gun melt heating electrostatic spinning apparatus, this device is convenient to assembling, be easy to operation, mobile electrostatic spinning can be realized prepare its micro nanometer fiber by the polymer lower to fusing point.
Photo-curing material (UV curing materials) is the special macromolecular material of a class, the prepolymer of its liquid state adds light trigger, after absorbing high-intensity ultraviolet light (UV), produce living radical or CATION, thus initiated polymerization, crosslinked and graft reaction, can be solid-state by liquid conversion within a certain period of time.Can be used as the presoma of solvent-free electrospinning in theory, but, report about the solvent-free electrostatic spinning technique of ultraviolet light is very rare, Chinese patent (patent publication No.: CN101021017A) discloses the method for no-solvent electrically spinning process for preparing micron and nanometer fiber, mainly under the initiation of ultraviolet light irradiation and initator, the precursor liquid containing activity double key functional group is made to be solidified into micro nanometer fiber, but it needs with reactive diluent used in combination according to certain ratio, precursor liquid is prepared cumbersome, and the fiber of preparation is generally shorter and irregular, solidification not exclusively, length maximum is 1 centimetre.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of solvent-free electrostatic spinning apparatus based on UV solidification is provided, this device can be used for continuous batch and prepares photo-curing material micro nanometer fiber, this device is simple to operate, effectively prevent organic solvent to volatilize the environmental pollution caused, safety and environmental protection, the large-scale commercial applications being particularly useful for photo-curing material micro nanometer fiber is produced.
To achieve these goals, technical scheme provided by the invention is as follows:
A kind of solvent-free electrostatic spinning apparatus based on UV solidification, comprise high voltage source, liquid storage mechanism, spinning nozzle, oxygen barrier mechanism, ultraviolet source and collector, described high-voltage power cathode connects spinning nozzle, spinning nozzle is communicated with the liquid storage mechanism of storage spinning precursor liquid, described collector connects high voltage source negative pole or direct ground connection, described oxygen barrier mechanism comprises the seal box of inner anaerobic or few oxygen, described spinning nozzle and collector are positioned at seal box, ultraviolet source is positioned at seal box or its ultraviolet light launched can inject seal box, ultraviolet source can irradiate spinning nozzle and collect interelectrode space.
Inventor sums up through great many of experiments and finds, method of electrostatic spinning prepares the solidification of UV curing materials micro nanometer fiber not exclusively, the general shorter and irregular reason of fiber is: electrostatic spinning is as a kind of method preparing micro nanometer fiber, use it for and prepare photo-curing material micro nanometer fiber, the large feature of specific area of its obtained micro nanometer fiber, this fibre morphology increases the contact area of prepolymer and oxygen, it is made to contact more abundant with the oxygen in air, be exaggerated the effect of UV curing materials oxygen inhibition phenomenon in the curing process, hinder the polymerizing curable of prepolymer, thus cause obtained photo-curing material micro nanometer fiber solidification not exclusively, fiber is generally shorter and irregular, have impact on large-scale production and the application prospect of fiber.
In order to address this problem, this device is provided with oxygen barrier mechanism, oxygen barrier mechanism need be first opened when this device uses, the content of oxygen in minimizing seal box oxygen in seal box all got rid of or try one's best, solvent-free spinning precursor liquid is injected liquid storage mechanism, and then open ultraviolet source and high voltage source, under the environment of isolation oxygen, carry out electrostatic spinning.In spinning process, pre-polymer solution is under action of high voltage, jet is formed from spinneret ejection, light trigger in jet absorbs the energy of ultraviolet light and produces living radical, living radical causes prepolymer polymerization reaction take place, with the splitting of fiber in the process that jet falls, finally on collector, form polymer micro-nanometer fiber, thus realize solvent-free electrostatic spinning.This device has built the spinning environment of anaerobic or few oxygen by oxygen barrier mechanism, effectively prevent the oxygen inhibition phenomenon at electrostatic spinning, thus the regular and continuous print photo-curing material micro nanometer fiber of obtained completion of cure, form in a large number, the precursor liquid used in spinning process is made up of the prepolymer of light trigger and photo-curing material, not containing other organic solvents, effectively prevent organic solvent to volatilize the environmental pollution caused, safety and environmental protection, the large-scale commercial applications being applicable to photo-curing material micro nanometer fiber is produced.
Further, the seal box of described oxygen barrier mechanism is vacuum desiccator, and described vacuum desiccator connects vavuum pump.
