In the various fields such as product and packaging.
But, PP plastics exist many not enough: predominantly black brittleness, poor dimensional stability, loss of properties on aging, and become
Type shrinkage factor is big, easy firing, simultaneously because its nonpolar feature, to such an extent as to be difficult to enter with other polar polymers, inorganic filler
Row is the most compatible, thus limits application and the development of PP.
In order to overcome the defect of PP, improve its impact strength, thermostability, ageing-resistant and creep resistance, it is necessary to pass through thing
PP is modified processing by reason or chemical method.In prior art, mainly changed by filling enhancing modified, blending and modifying and grafting
Property.Wherein apply wider for filling enhancing modified method, mainly by adding other polymer, inorganic filler and compatilizer,
Reach to improve the purpose of material property.
Publication No. CN 105419103 A discloses a kind of aging resistance and strengthens the preparation method of PP plastics, uses blended changing
Property, modified carbon dioxide, PP, styrene, age resister, zinc stearate are carried out mixing by the method, then at 190-270 DEG C
Carry out extruding pelletization, i.e. obtain the MODIFIED PP master batch of a kind of ageing resistace and excellent strength.Notification number is that CN1141335 C is public
Open the enhancing of a kind of rigid particles, the preparation method of toughness reinforcing polypropylene material, used inorganic particulate to be filled with, make performance obtain
To strengthening, first the method use rubber coated rigid particles, such as wollastonite, Pulvis Talci, glass microballoon, Muscovitum or short glass fiber etc.,
Then mix with PP, maleic anhydride graft PP, antioxidant, then use double-screw extruding pelletizing, i.e. obtain rigidity reinforced,
Toughness reinforcing PP material.Publication No. CN 101074306 A discloses the MODIFIED PP of a kind of inorganic core shell structure, and the method is the most certainly
SiO2/CaCO3 nuclear shell structure nano compound ion processed, is subsequently adding PP, coupling agent carries out mixing granulator, obtains a kind of enhancing and increases
Tough PP material.
Inorganic fill particle adds to can improve its toughness in MODIFIED PP, also can improve material shock resistance and heat change
While shape temperature, do not reduce its hot strength and rigidity.And nano inorganic material is from rising so far, because it has surface and boundary
Face effect: the ratio of nanocrystal grain surface atom number and total atom number diminish with particle diameter and after being increased dramatically caused in nature
Change；Small-size effect: when nanoparticle size and optical wavelength, the de Broglie wavelength of conduction electronics and the phase of superconducting state
The dry physical features size such as length, transmission depth quite or less time, its periodic boundary is destroyed so that its sound, light,
Electricity, magnetic, the excellent performance such as thermodynamics；Quantum size effect: when the size of particle reaches nanometer scale, near fermi level
Electron energy level is split into discrete energy levels by continuous state；Macro quanta tunnel effect: microcosmic particle has and runs through the ability of potential barrier and claim
For tunnel-effect, the intensity of magnetization of nanoparticle etc. also has tunnel-effect, and they can produce through the potential barrier of macroscopic system
Change, this macro quanta tunnel effect being referred to as nanoparticle.Gradually it is applied to every field, in terms of modifying plastics also
Extensively application.Nanoparticle should carry out the process of suitable surface during carrying out polymer-filled, reduces the surface of particle
Can, and increase in plasticizing process the interfacial interaction between particle and polymer, it is finally reached nanoparticle homodisperse
Effect.
Graphene oxide (graphene oxide GO) is powdered graphite product after chemical oxidation and stripping, oxidation
Graphene is single atomic layer, can expand to some tens of pm at any time on lateral dimension, and its surface oxygen functional group increases
And make character active.
