Description
Technical field
The invention belongs to composite conducting fiber and preparation field thereof, particularly a kind of polylactic acid/sliver composite conductive fiber and preparation method thereof.
Background technology
As a kind of high-tech, high value added product, conductive fiber had both had the very excellent electric property of conductive compositions, had both again the pliable and tough machinability of textile fabric, and since it comes out, marketing development has the history of more than 50 year.Conductive fiber is except excellent textile performance, also there is excellent electric conductivity can be used for eliminating electrostatic, electromagnetic wave absorption, and there is unique status in the antistatic field of chemical fibre product, therefore it not only can be used for the antistatic explosion-proof clothing of the industry such as petrochemical industry, military project, but also can be used for the dust-free sterile clothes preparing microelectronics, medicine, food, communication, precision instrument, biotechnology field.
The preparation method of conductive fiber has many kinds, and along with deepening continuously of research, according to final performance and the preparation technology of obtained fiber, people have progressively eliminated some preparation methods fallen behind.At present, the method being prepared into conductive fiber mainly contains three kinds; One is make fiber surface form the coat of metal at the textile surface physics such as fiber or chemical method; two is chemically form semiconductor lamella at fiber surface; three is that electrically conductive particles is mixed in spinning melt, is made the conductive fiber of skin-core structure or island structure by composite spinning.
Surface metalation is one of the important channel realizing material especially flexible nonmetal material (fiber, fabric, film) functionalization.The metallized fabrics that chemical silver plating method obtains, its capability of electromagnetic shielding is good, except antioxidant anticorrosive ability is strong, also has antibacterial and deodouring, anlistatig function.In today that environmental consciousness strengthens day by day, it more and more demonstrates huge market potential, although thus enjoy the favor of people. and silver-colored fiber has a lot of advantages, and it also exists some problems at present on Synthesis and applications.First, in the preparation method of silver-colored fiber, because use metal salt solution in a large number, there is serious liquid waste processing problem, easily cause environmental pollution in chemical plating.Although coating, vacuum plating method and sputtering method avoid the liquid waste processing problem of chemical plating, itself complex process, operation inconvenience.Moreover coating can not form good metal coating very well, and adhesion is weak.Vacuum plating method also also exists metal level and is combined loosely with base material, easily comes off.And the general feel of fabric that above method obtains is very poor, mostly all can not clean, there is environmental pollution etc. in production.
Summary of the invention
For the deficiencies in the prior art, the present invention will provide a kind of method preparing polylactic acid/sliver composite conductive fiber.The method is simple to operate, nontoxic pollution-free, and fiber is combined with silver layer closely, difficult drop-off.
Technical scheme of the present invention is: polyvinyl alcohol is plastified modified and polylactic acid blend, after melt spinning, polyvinyl alcohol dissolution is fallen to obtain polylactic acid porous fiber, then adopt Ultraviolet irradiation method that silver nitrate is reduced in the surface and hole of polylactic acid porous fiber, obtain polylactic acid/sliver composite conductive fiber.Its step is as follows:
(1) plasticization and modification of polyvinyl alcohol: polyvinyl alcohol, polyalcohol, flow improver additive are put in high-speed mixer, the mass ratio of polyvinyl alcohol, polyalcohol, flow improver additive is 70-90:10-25:2-10, mixes under the condition of 50 DEG C-70 DEG C; Then use double screw extruder or single screw extrusion machine, 150 DEG C-190 DEG C melt blending granulations, obtain plasticised polyvinyl alcohol section;
(2) spinning of blended fiber: plasticised polyvinyl alcohol section step (1) obtained is put in conventional melt spinning machine with polylactic acid slice and carried out spinning, described plasticised polyvinyl alcohol section is 5-35:95-65 with the mass ratio of polylactic acid slice, spinning temperature 190 DEG C-220 DEG C, spinning speed is 200m/min-1000 m/min, the polyving alcohol/polylactic acid blended fiber that to obtain take polyvinyl alcohol as island, PLA is sea;
(3) the molten of polyvinyl alcohol removes: the polyving alcohol/polylactic acid blended fiber that step (2) is made is placed in 40 DEG C-90 DEG C water 20-60 minute, obtains polylactic acid porous fiber;
(4) Ultraviolet irradiation method prepares polylactic acid/sliver composite conductive fiber: concentration inserted by polylactic acid porous fiber is soak in the liquor argenti nitratis ophthalmicus of 40-200g/L after 5-50 minute to take out, ultraviolet high-pressure mercury lamps is adopted to irradiate it, under power 250W-20KW, irradiation 1-10 minute, obtains polylactic acid/sliver composite conductive fiber.
