At present; The preparation method of nano fibrous membrane mainly utilizes the tow of electrostatic spinning apparatus ejection nanoscale; Through changing the emission direction of nanometer tow, finally drop on the fibrofelt of the bundles of nanofibers formation non-weaving cloth shape on the receiving system, i.e. nano fibrous membrane.But; Owing to the method that adopts electrostatic spinning to prepare nano fibrous membrane mainly is applicable to the high polymer that can carry out the solution spinning, this just makes this method of using on material chosen, have significant limitation, the nano fibrous membrane poor mechanical property for preparing with electrospinning process in addition when preparing nanofiber; Be difficult for using separately; But again owing to is made up of continuous fiber through the nano fibrous membrane of electrospinning process preparation, and its thickness is difficult to control, if it is attached to the enterprising enforcement usefulness of base material lining; The uniformity of tunica fibrosa and with the adhesive of base material lining on have very big defective again; Influence result of use, prepare nano fibrous membrane with electrospinning process simultaneously and also be difficult to realize industrialization, caused the limitation of nano fibrous membrane on application of this method preparation thus.The report that at present electrostatic spinning technique is prepared nano fibrous membrane has had a lot, does not also appear in the newspapers in the method that the enterprising capable face coat of base material lining prepares nano fibrous membrane but will process slurries through the nanofiber that multicomponent blend phase separation method prepares.
Summary of the invention
To above-mentioned existing problems, the objective of the invention is to be to provide a kind of application novel three-dimensional nano-fiber composite film material and preparation method thereof widely, to achieve these goals, technical solution of the present invention is:
A kind of three-dimensional manometer composite fiber membrane, said three-dimensional manometer composite fiber membrane is made up of base material lining and superficial film, and superficial film is the thermoplastic polymer nano fibrous membrane that forms through at the surperficial blade coating of the enterprising row of base material lining,
Described base material lining is a kind of in woven fabric or knit fabric or the nonwoven.
A kind of preparation method of three-dimensional manometer composite fiber membrane, preparation method carry out according to the following steps:
A at room temperature obtained the nanofiber emulsion through mulser in 6-10 minute with 10000 rev/mins rotating speed emulsification with thermoplastic polymer nanofiber and solvent in the ratio of mass ratio 0.5-2: 98-99.5;
B with nanofiber emulsion prepared in the A step on base material lining surface the technology through blade coating carry out face coat at normal temperatures; Obtain the three-dimensional manometer composite fiber membrane after to be dried, wherein the coating thickness of nanofiber emulsion on the base material lining is the 1-3 millimeter.
Solvent in the said steps A is deionized water and isopropyl alcohol or formic acid or wherein a kind of mixture of acetate.
Thermoplastic polymer nanofiber in the said steps A is a kind of in the copolymer p VA-co-PE nanofiber of polyethylene terephtalate nanofiber or polycaprolactam PA6 nanofiber or polypropylene PP nanofiber or polylactic acid PLA or polyethylene glycol PVA and polythene PE.
Owing to adopted above technical scheme, the present invention has the following advantages:
The preparation method of three-dimensional manometer composite fiber membrane of the present invention; The nanofiber that adopts is the thermoplastic polymer nanofiber; Its reason is that this thermoplastic polymer nanofiber can prepare through the co-mixing system phase disengagement method; This method has the technology characteristic of simple, is easy to realize the suitability for industrialized production of nanofiber; The solvent of selecting can so that this thermoplasticity nanofiber can be evenly also stable the effect of mulser under be scattered in the middle of this solvent; With this thermoplasticity nanofiber in the solvent of correspondence with utilizing mulser to process slurries; Can make form evenly also stable be scattered in solvent of nanofiber with short fiber; When this makes in next step technology and with above-mentioned slurries the base material lining to be carried out face coat; The thermoplastic polymer nanofiber that is dispersed in the solvent on the one hand can well-proportionedly be distributed on the base material lining; On the other hand because nanofiber is to be present in the middle of the slurries with the short fiber form; It is inner after face coat, to be easy to penetrate into the base material lining with solvent, and nano fibrous membrane and base material lining after to be dried like this just have adhesive more closely, have solved nano fibrous membrane because its poor mechanical property is difficult to the difficult problem of independent use.The three-dimensional manometer tunica fibrosa of preparing by preparation method of the present invention have thickness evenly, good dispersion, mechanical property is good, specific area is big advantage, can be widely used in a plurality of fields such as cleaning material, biological medicine, sensor, radiation proof.Preparation method's technology of the present invention is simple, is easy to realize suitability for industrialized production.
