Description
Technical field
The present invention relates to technical field of nano material, more particularly to a kind of nano-PVC stabilizing material and preparation method thereof.
Background technology
Nanometer green wood material formula is one and within 100 nanometers, in space, directly sorts atom by change naturally and divide
The project of the new nano material that son is created out.Nanometer new material and the field are rising for modern strength and modern technologies innovation
Point, the discovery of new rule and principle are founded with brand-new theory and give basic science, there is provided new chance, this can become perhaps
The new power of multi-field important reform.Nanometer green wood material formula is tiny due to SAIZU, has much peculiar performance.1988
Baibich etc. has found that magnetoresistive ratio reaches 50 percent for the first time in nanometer Fe/Cr MS, with general ME ratios
Get up to want a big rank, and be negative value, respectively to the same, referred to as GMR.Afterwards also nanometer system, tunnel knot and
Huge ME is found in UV-9rovskite structures, membrana granulosa.The inside UV-9rovskite structures were to find and have in 1993
Have very big ME, be called CMR, find in tunnel knot for TMR.
Nanometer film is divided into membrana granulosa and dense film.Membrana granulosa is that nano-particle sticks together, centre have extremely tiny between
The thin film of gap.Dense film refers to that film layer is fine and close but crystallite dimension is nano level thin film.Can be used for：Gas catalysis（Such as vehicle exhaust
Process）Material；Filter material；High density magnetic recording material；Light-sensitive material；Flat-panel screens material；Superconductor etc..
Nanotechnology need not be put as a kind of emerging science and technology of most market application potential, its potential importance
Doubt, some developed countries all put into substantial amounts of fund and carry out research work.As colonial has set up research in nanotechnology center, Japan
Portion of culture and education section is classified as nanotechnology as one of four big primary study exploration projects of material science.
The synthesis of directional nano array carbon nanotube, is completed by Inst. of Physics, CAS Xie Sishen researcher etc..They
Aperture about 20 nanometer, CNT that length about 100 micron are efficiently prepared using chemical gas-phase method.And thus prepare nanometer
Pipe array, up to 3 millimeters × 3 millimeters, between CNT, spacing is 100 microns to its area.
But, compared with the advanced technology of developed countries, we also have very big gap.The German Ministry of Science and Technology was once
Through making prediction to nanotechnology future market potential：They think that nano structure device market capacity is up to 2000
637500000000 dollars, nano-powder, nano composite ceramic and other nano composite material market capacitys are up to 545,700,000,000 dollars,
Nanofabrication technique market capacity is up to 44,200,000,000 dollars, and the assessment technique market capacity of nano material is up to 27.2 hundred million U.S.s
Unit.And the breach of prediction markets may be in information, communication, environment and medicine and other fields.
On October 19th, 2011, EU Committee passed through the definition to nano material, again this definition was carried out afterwards
Explain.According to the definition of EU Committee, nano material is a kind of powdery being made up of basic granules or lumps are natural or people
Work material, one or more three-dimensional dimensions of this basic granules are between 1 nanometer to 100 nanometers, and this basic granules
Total quantity account for more than 50% in all total number of particles of whole material.
1 nanometer is equal to part per billion meter.On nanoscale, some materials have a lot of specific functions.Nano material
It is used widely in the work and life of people.
The applied research such as nanotechnology fundamental research and new material exploitation is obtained for quickly development, and is passing
The industries such as commons material, medical device, electronic equipment, coating are widely used.In terms of industrialized development, except nanometer
Powder body material tentatively realizes outside large-scale production that in a few countries such as the U.S., Japan, China nano meter biomaterial, nanometer are electric
The products such as sub- device material, nanodoc diagnostic materials are still in developing the stage.Global nanometer new material market in 2010
Up to 22.3 hundred million dollars, annual rate of growth is 14.8% to scale.A few years from now on, as various countries add to nanotechnology applied research input
Greatly, nanometer new material industrialization process will greatly speed up, and market scale will have and high-volume increase.Organic face in nano-powder material
Several products such as material, nano zine oxide, nano silicon oxide have formed certain market scale；The extensive nanometer of application of nanopowder
The materials such as ceramic material, nano-textile material, nanocomposite coatings are also succeeded in developing, and tentatively achieve industrialization production,
Nano-powder granule is just stepping up from experimental research achievements to product industry metaplasia in the application of medical diagnosiss preparation, microelectronic
Produce direction transfer.
