Description
Technical field
The present invention relates to technical field of polymer materials, and in particular to one kind being based on polyacrylic modified material.The material
At least it is grouped as by following three kinds of groups：Macromolecule matrix, inorganic nano-particle, hyper-branched polymer, can also contain and other groups
Point.The characteristics of modified material, is there is higher intensity and toughness simultaneously, while also having high fluidity.
Background technology
In all plastics, polyacrylic cost is minimum, and density is minimum, and processing and forming is also easiest to, therefore polypropylene is vapour
The most high molecular material of automobile-used amount.While polypropylene material provides a large amount of high-quality low-cost materials for auto industry, automobile
Light-weighted development also also puts forward higher requirements parts with pp material performance.In the premise for not reducing product standard
Lower realize is thinned, and achievees the purpose that automotive light weight technology.But the design that is thinning of auto parts and components is not simply to promote material
Rigidity realize the reduction of product thickness, weight, and should be ensure thin-wall part have good shock resistance,
Under the premise of dimensional stability, improve the rigidity and processing fluidity of material as far as possible so that the molding cycle of product shorten and
Has good shape support effect, to meet the light-weight design requirement of automobile, this just proposes polypropylene material high
Requirement.
People have carried out extensive work and have carried out toughening modifying research to PP.The various thermoplastic elastic bodies of generally use
It is blended with PP, forms the blend of impact strength and excellent in low temperature toughness, such as polypropylene/thermoplastic elastomer (TPE) (PP/POE)
Extensive use is obtained, but the mechanical strength of PP and rigidity have larger reduction and loss.It is widely used various inorganic at present
Filler (calcium carbonate, talcum powder, mica and wollastonite etc.) is filled, reinforcement, to improve the dimensional stability, heat-resisting of material
Property, rigidity, while reducing material cost.Common thermoplastic elastomer (TPE) and inorganic filler is added simultaneously in PP systems, although
Intensity and toughness can be improved simultaneously, but the amplitude that the two improves simultaneously is little, and mobility substantially reduces.
Invention content
In view of the deficiencies of the prior art, technical problem to be solved by the invention is to provide a kind of high fluidity high-strength and high ductilities
PP composite material and preparation method thereof, its main feature is that inorganic nano-particle and hyper-branched polymer is selected to cooperate with activeness and quietness
Polypropylene, while mobility is improved.
To achieve the above object, the present invention uses following technical scheme：
A kind of high flowing polypropylene composite material with high strength and toughness, is made of the raw material of following weight percent meter：
Polypropylene 69-97wt%；
Inorganic nano-filler 1-20wt%；
Hyper-branched polymer 1-30wt%；
Antioxidant 0.1-1wt%.
Preferably,
A kind of high flowing polypropylene composite material with high strength and toughness, is made of the raw material of following weight percent meter：
Polypropylene 84.6.%, inorganic nano-filler 5%, hyper-branched polymer 10%, irgasfos 168 0.4%.
In above-mentioned PP composite material system,
The inorganic nano-filler is acicular wollastonite, the talcum powder of sheet, mica powder or montmorillonite；Or it is received for carbon
Mitron, graphene oxide etc..
Further, the grain size of the inorganic nano-filler is between 10~500nm.
The hyper-branched polymer is dendroid dispersibility toughener.
For the polypropylene under 230 DEG C, the test condition of 2.16kg, the copolymerization that melt index is 30-120g/10min is poly-
Propylene.
The antioxidant includes primary antioxidant and auxiliary anti-oxidant；Wherein, primary antioxidant 3,5- di-t-butyl -4- hydroxyl benzyls
Base diethyl phosphate (3114), four [β-(3,5- di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol esters (1010), thio two
One or more of propionic acid octadecyl ester (DSTP)；The auxiliary anti-oxidant is diphosphorous acid pentaerythrite distearyl alcohol ester
(618) or three (2,4- di-tert-butyl-phenyls) phosphite esters (168).
The preparation method of above-mentioned high flowing polypropylene composite material with high strength and toughness, its step are as follows：
(1) polypropylene, hyper-branched polymer and antioxidant first are weighed by following parts by weight, be uniformly mixed, it is former to obtain mixing
Material, then weighs inorganic nano-particle again；
(2) it after drying above-mentioned mixed raw material, is placed in the main feeding bin of meshing co rotating twin screw extrusion, through feeding spiral shell
Bar is added in the machine barrel of extruder, inorganic nano-particle is added to from melt zone charge door in extruder, extruder screw
A diameter of 35mm, draw ratio L/D are 40, and each zone temperature that main barrel is exported from charge door to head is set as：190℃、200
DEG C, 200 DEG C, 200 DEG C, 200 DEG C, 210 DEG C, 210 DEG C, engine speed be 250 revs/min, through melting extrusion, cooling, granulation, baking
PP composite material is made in dry-cure.
The beneficial effects of the invention are as follows：Hyper-branched polymer has excellent toughening effect, and can significantly improve PP's
Melt flowability is the characteristic brought by its special dendritic structure.There is long-chain-segment flexible in dendritic structure,
Molecule interchain plays the role of a kind of connection, cushioning effect, enable system when being impacted from absorb energy, shock absorbing,
Crazing is reduced because stress develops into the chance of crackle, to improve the impact strength of system；And dendritic structure surface is big
The long flexible chain section of amount is in space three-dimensional extended position, and space three is more readily formed by the interaction of strand in system
Reticular structure is tieed up, impact force of the external force to system is further buffered, to further promote toughening effect.In addition, compared to biography
It unites linear toughener, hyper-branched polymer is in space spherical structure, has smaller hydrodynamic radius, shows significantly to moisten
Slip low melt viscosity characteristic can substantially improve the melt flows of the polyolefine materials such as PP while promoting material impact intensity
Property, there is better dispersion performance to inorganic nano-particle, reach increasing of the inorganic nano-particle to material to further improve
Potent fruit, so this product is especially excellent in inorganic nano enhancing system performance.
