Description
Technical field
The invention belongs to nano non-woven fabric technical field of material, and in particular to a kind of method of electrostatic spinning prepares nanometer and melted
The method of blown non-woven fabric.
Background technology
Nanometer technology is the study hotspot of current scientific research field, and the preparation of nanofiber is always what numerous scientists were concerned about
Emphasis, wherein electrostatic spinning are confirmed in nearly theoretical research by comparison system in 10 years and experiment.Electrostatic spinning technique into
To prepare the important method of superfine fibre and nanofiber.But the technology has that yield is extremely low, fibre structure is single, it is impossible to very well
Realize that fiber alignment is consistent, it is most of be it is disorderly and unsystematic, it is random strong.It is difficult to reappear.
Microbedding coextrusion technology has had decades, but only local expanded application at present till now, more
It is to be in the laboratory research stage.Microbedding co-extrusion technology refers to two or more polymer being formed by coextrusion tens
Layer or even thousands of layers of alternate multiple composite, individual layer thickness can be as thin as micro/nano level.Microbedding coextrusion technology can make function
In-situ fibrillation of the filler component in polymeric matrix, so as to prepare the alternate multiple composite of high-performance and functionalization.
The excellent properties of different polymer can be got up to prepare work(by microbedding coextrusion technology by alternate multiple mixed binding
Energy composite, when the composite number of plies is enough, individual layer can be as thin as the one-dimensional nano structure suitable with Chain Dimensions, this
Unique microlayer structures are planted by composite functional diversities.For filled-in composite, nano-scale dimension Rotating fields go out
It is two dimension by Simplified Three-dimensional that the distributions of filler particles, which can now be made, is studying and is improving interfacial property（If diffusion is with bonding）In terms of
Can not be using complicated threedimensional model analysis.
Rainbow film is the more microbedding co-extrusion technology application examples of current application amount.Utilize two kinds of different heat of refraction coefficient
Plastic transparent resin（Refraction coefficient difference 0.03）, more than 30 layers are made through MULTILAYER COMPOSITE coextrusion, is uniformly put down on thickness direction
Capable alternating thickness is the 0.015-0.05 mm film for having rainbow effect, and with the difference of viewing angle, color is different.It five
The color effect of variegation bright-coloured is that, according to optical refraction, interference, principle of reflection, have coloured silk when the zone of reflections is in the wave-length coverage of light
Rainbow phenomenon is produced, and the color that rainbow film is reflected is determined by the wavelength of reflected light.So it show it is motley
Gorgeous color.Preparing rainbow film can also be prepared using the method for light coral and the method for multicoating is carved, but both sides
Method manufacture is costly, and the area of manufacture is small, and speed of production is low, is only suitable for anti-counterfeiting mark, and trade mark etc. is used.And reflection multilayer
The compound rainbow film manufacturing expense of plastics is low, and production scale is big, and a unit can produce tens thousand of square metres in one day, is adapted to a wide range of
Application, such as decoration material, printing, packaging in terms of use.Especially effect is fine in candy, fresh flower packaging, and has
There is sizable application prospect.
Before 2005, the technology of preparing of microbedding co-extrusion technology and rainbow film is substantially public by Mearl companies of the U.S., Angerer
Department and Taiwan He companies etc. hold, wherein there is 10 multinomial patents to cover the key point of technology of preparing, the EDI in the nearest U.S. is public
Department, the Yang Weimin of Beijing Chemical Engineering College, the Guo Shaoyun of Sichuan University, blue sky, absolute sincerity company etc. successively release patent type technology solution
Determine puzzlement thin-film barrier, optical, pin hole fault, flaw fracture, stretch-resistance and the problem of electric property.
