Description
Technical field
The present invention relates to a kind of antimicrobial macromolecule material, especially relate to a kind of antibacterial polypropylene resin and preparation method thereof.
Background technology
Polypropylene PP is as one of five large general-purpose plastics, density is little, production cost is low, comprehensive mechanical property is good, nontoxic, corrosion-resistant, be easy to processing and the advantages such as recovery, be widely used in various places, such as fields such as household electrical appliance, inner and outer decorative parts of automobile, body-building apparatus, office appliance, daily necessities, toy and sanitary ware.The polypropylene preparation is exposed in bacterium mould space, and its surface can grow a large amount of bacteriums, and people's health in serious harm.Progress and Economic development along with science and technology, people are to the raising of healthy and environmental consciousness, recognize gradually, polypropylene itself does not possess anti-microbial effect, therefore exploitation has the Novel polypropylene material of the function of antibacterial, can kill within a certain period of time mould, the bacterium of product surface or restrain its breeding, avoid passing through between person to person, thing and thing, people and the thing mould, the bacterial cross-infection of polypropylene material material products, reduce transmission of disease.Environmental protection cause and people healthy there is very important realistic meaning.The at present common employing of antibacterial polypropylene material of preparation is directly added antibiotic raw material in polypropylene product, but this makes polypropylene articles variable color in preparation process easily, inorganic antiseptic disperses inhomogeneous in acrylic resin, agglomeration often occurs, has affected the mechanical property of goods.
At present, about polyacrylic development and application mainly be with the antiseptic-germicide physical blending in polypropylene PP resin.As: 1, publication number is that (application number is CN102336958A: patent of invention 201110172759.4), disclosed " a kind of flame-retardant antibacterial transparent polypropylene material and preparation method thereof " adopts the method for fire retardant and the composite use of antiseptic-germicide so that the polypropylene material of preparation has fire-retardant and anti-microbial effect simultaneously, the density of being fuming during the product burning is very low, and the while is not easy to change, cost is low; 2, publication number is the patent of invention of CN102140199A (application number is 201010103183.1), disclosed " a kind of preparation method of Novel polypropylene antibacterial matrices " is distributed to the nanometer silver powder in the solvent of nonpolar or low-pole, then adds polypropylene chip and makes its dissolving.By the desolventizing of thermal backflow technology, pulverize after the drying, prepare polypropylene antibacterial master batch by Screw Extrusion at last.3, publication number is the patent of invention of CN102424709A (application number is 201110381914.3), disclosed " a kind of antibacterial polypropylene material and preparation method thereof " is disclosed to mix polypropylene, white oil, antiseptic-germicide, lubricant, oxidation inhibitor, join and melt extrude granulation in the twin screw extruder, the anti-biotic material of preparation contains antiseptic-germicide, good anti-bacterial effect is antibiotic lasting and mechanical property is excellent.4, (application number: patent of invention 201110434148.2), " a kind of high antibiotic polypropylene composite material and preparation method thereof " disclose a kind of passing through first to nano-TiO to publication number CN102558676A
2Particle carries out the dopen Nano TiO that doping treatment obtains
2Particle, the modification TiO that obtains through coupling agent treatment again
2Particle is further with modified Nano TiO
2Particle and polypropylene fusion are extruded and are made high antibiotic polypropylene composite material.5, (application number is: patent of invention 201010151580.6), " nanometer antibacterial polypropylene pipe material and preparation method thereof " announced a kind of nano-antibacterial Pp Speciality For Water Pipes and preparation method thereof to publication number CN101818834A.1～15% of polypropylene weight added the nano-class antibacterial masterbatch in the acrylic resin mix with stirrer, carry out the melting heating, obtain the mixture of the acrylic plastering of nano-antibacterial master batch, for the preparation of the nano-antibacterial internal layer; Then make the acrylic plastering and the common plastics that contain nano-antibacterial carry out synchronous co-extrusion, make the tubing that comprises acrylic plastering skin and nano-antibacterial internal layer, at last typing cooling.
Employing is with antiseptic-germicide and polyvinyl resin physical mixed, and the problem that this method exists is: antiseptic-germicide is easily lost, and does not have long acting antibiotic.
