In polypropylene toughness-increasing modified research, the most frequently used toughening methods are exactly that flexible polymer is introduced in plastic substrate Thing, when system is subject to external impacts, absorbs a large amount of punching by causing the crazing and shear yielding of flexible polymer surrounding matrix Energy is hit, so as to improve the toughness of matrix.But this method has fatal weakness, although that is, the toughness of polypropylene matrix is improved , but often result in the reduction of tensile strength and hardness；On the other hand, for the Pp System of addition inorganic antiseptic, draw Enter flexible polymer to be easy to clad be formed in inorganic antiseptic particle surface, reduce the antimicrobial efficiency of inorganic antiseptic.Cause This, simply adds flexible polymer in inorganic antiseptic/Pp System, although improve polyacrylic to a certain extent Toughness, but the antimicrobial efficiency with sacrificial inorganic antibacterial is as cost to a great extent.Therefore, ensureing that inorganic antiseptic is excellent While different anti-microbial property, how to improve Mechanical Properties of PP is one of difficult point of antibacterial polypropylene material research.
Many researchers using super long chain macromolecule is introduced in polypropylene matrix, using overlength strand shape in the base Into the framing structure of physical entanglement, when material is subject to external force to act on, in matrix, the skeleton of this entanglement absorbs and transmits impact Can, to play a part of activeness and quietness.For example, using the PE modified polypropylene that molecular weight is high so as to polypropylene melt Melt blending and form linear interpenetrating networks or physical cross-linked network, when material under external force, there is large deformation in network, absorb outer Boundary's energy, plays the effect of activeness and quietness.But ultra-high molecular weight polyethylene molecular weight is very long, mutually tangle each other, even if More than melting temperature, the state of elastomer is also kept not with mobility.
The present invention adopts linear low density polyethylene for carrier, and the alkane and super high molecular weight for adding certain low-molecular-weight gathers Ethylene melt blending generates low viscous ultra-high molecular weight polyethylene master batch；Using nano zine oxide or titanium dioxide as inorganic Then polypropylene, ultra-high molecular weight polyethylene master batch, inorganic antiseptic, graft polypropylene and other auxiliary agents are passed through by antibacterial Double screw extruder melt blending extrusion obtains activeness and quietness antibacterial polypropylene material.For preparing activeness and quietness antibacterial polypropylene The requirement of material, the present invention have the property that：（1）Nano zine oxide or titanium dioxide are selected as inorganic antiseptic；（2）Choosing The ultra-high molecular weight polyethylene with overlength strand is selected as organic filler, and by the use of linear low density polyethylene as carrier Low viscous ultra-high molecular weight polyethylene master batch is generated with ultra-high molecular weight polyethylene melt blending extrusion；（3）Effectively improving On the premise of polypropylene antibacterial activity and mechanical strength, as far as possible using a small amount of inorganic antiseptic and ultra-high molecular weight polyethylene Master batch.
Compared with existing antibacterial polypropylene material, the present invention has the effect that：The polypropylene material that the present invention is prepared Material antibacterial more rapidly, it is more longlasting, safer；Simultaneously present invention uses super long chain macromolecule improves material as filler Mechanical property, widened the range of application of antibacterial polypropylene material.
