Description
Technical field
The present invention relates to technical field of polymer materials, more specifically, belong to a kind of food medical grade high heat-resisting high saturating
Bright antibacterial polypropylene material and preparation method thereof.
Background technology
With developing rapidly for science and technology, people also improve constantly to the daily life quality of oneself.Antibacterial polypropylene
(PP) it is a kind of novel ecological functional material, due to good mechanical performance, anti-microbial property and workability energy, while right
Improve the ecological environment, keep human health significant, therefore be widely used in food transparent wrapper, container, doctor
Treat the fields such as apparatus, household supplies and general industry.However, antibacterial PP belongs to partially crystalline polymer, crystallization rate is relatively
Slowly, larger spherocrystal is easily formed, light is difficult through whole product, therefore, the glossiness and the transparency of product are poor, outward
Sight lacks aesthetic feeling, it is restricted in application field.
After transparent modified, the extremely homogeneous refinement of spherulitic crystal structure, glossiness and the transparency are significantly improved antibacterial PP, and
Crystallization temperature, Vicat softening point, rigidity and other performance are all improved, and compared with common PP, combination property is obtained transparent PP
Improve.Transparent PP material in transparency, glossiness, density, pliability, rigidity, chemical resistance etc. and conventional transparent material, such as
PC, PET, PS, PVC etc. are compared to many excellent properties.The application of current transparent PP material widely, can be used to note
Penetrate, be blow molded, blowing drawing, casting films, extruding, thermoformed articles etc..The raising of these combination properties, enhances the ring of transparent PP product
Border adaptability, and expand and use scope, at home and abroad rapidly developed.
The content of the invention
It is contemplated that there are provided a kind of food medical grade heat-resisting high-transparency antibacterial polypropylene material high, its glossiness
Good, heat-resist, transparency is high, durable antibacterial effect is efficient.
The technical solution adopted in the present invention, i.e., a kind of food medical grade heat-resisting high-transparency antibacterial polypropylene material high, by
Hereinafter raw material by weight percentage is constituted：
Above-described atactic copolymerized polypropene is 5~25g/10min of solution flow rate, Izod notched impact strength
More than 15kJ/m2Acrylic resin.Described HOPP is 15~45g/10min of solution flow rate, and cantilever beam lacks
5~15kJ/m of mouth impact strength2, bending modulus is the acrylic resin of 1500~2000MPa.
The Millad NX8000 forth generation glucitols that described transparent nucleater is selected from Milliken companies of the U.S. is transparent
Nucleator.
Described antibacterial matrices are organic and inorganic antiseptic one or more mixture master batches, and inorganic resists
Microbial inoculum is the mixture of Ag Loaded Zeolite Antimicrobial and nano zine oxide, calcium oxide, magnesia, titanium dioxide etc., organic antibacterial
Agent is Chitosan-phospholipid complex.
Described lubrication dispersing agent be EBS, Tissuemat E, calcium stearate, zinc stearate and silicone powder in any one or
Several combinations.Described antioxidant is Hinered phenols antioxidant, organic phosphites antioxidant and monothioester kind antioxidant
Compound.
On the other hand, above-mentioned food medical grade heat-resisting high-transparency antibacterial polypropylene material high is prepared present invention also offers one kind
The method of material, it is characterised in that comprise the following steps：
(1) component and proportioning as described in claim 1 weigh raw material；
(2) above-mentioned material is put into high-speed mixer and mixing 5~8 minutes, pre-composition is obtained after being well mixed；
(3) melting extrusion in double screw extruder by pre-composition again, while by tie rod, air-cooled, pelletizing after water cooling,
Particle is separated out through vibrosieve, final products are packaged to be after being well mixed.
According to the mechanism of nucleation of nucleator, forth generation Sorbitol Nucleator has the aggregation property of voluntarily physics polymerization,
May be dissolved in melting PP, form homogeneous phase solution.When polymer is cooled down, clarifier first passes through self aggregation and acts on forming threadiness
Network, the network is not only uniformly dispersed, and with great surface area.With further cooling, PP is attached in orientation first
Form layered crystal under raw effect, then other PP segments are along fiber axially arrangement crystallization.Therefore the nucleation that improve PP is close
Degree, makes PP form the spherocrystal of homogeneous refinement, reduces to light scattering and refraction, transparency increase.
The present invention is matched by selecting the addition of suitable resin raw material and various auxiliary agents, has prepared glossiness
The polypropylene articles that good, heat-resist, transparency is high, anti-microbial property is excellent.Compared with prior art, advantages of the present invention exists
In：A) atactic copolymerized polypropene and HOPP are carried out into efficient combination, makes the material of preparation in rigidity, toughness and heat resistance
Aspect reaches balance；B) addition of forth generation transparent nucleater, increases polyacrylic nucleus, and crystallization rate is accelerated, crystallization
Crystal granular, the transparency increases, at the same can also the raising rigidity of final products of larger amplitude, low-temperature flexibility, heat resistance and into
The type cycle；C) adding organic and inorganic antiseptic one or more mixture master batches, to cause that polypropylene material has excellent
Different antibacterial effect.And simple production process, conveniently, raw material economics is easy to get, and product can be widely applied to saturating for machine-shaping
The field such as bright property requirement food containers high and medical equipment.
