Abstract
This invention is a polymer/montmorillonite-garlicin nanometer antibiosis composite. Its raw materials and weight amount is that polymer 100, montmorillonite-garlicin 0.1-10, disperse medium 0-400, cross linking agent, accelerator 0-1. The polymer is composed by silicone rubber gum which is chosen from methylsilicone, pyro-methylsilicone and additive type methylsilicone, polyurethane which is chosen from PE, PVC and PP, or the polymer of two compounds. The functional intercalator of montmorillonite-garlicin is garlicin.

Description
Technical field
The invention provides a kind of polymer-montmorillonoid-gallicin nano-antibacterial composite material and preparation method thereof, class montmorillonite filled one base polymer/montmorillonite-gallicin nano-antibacterial composite material that forms in the polymeric matrix that specially refers to the garlicin intercalation modifying and preparation method thereof.
Background technology
Contain unique garlicin in the garlic, garlicin all has various bacteria, fungi, virus to be killed and restraining effect, be called as " natural broad-spectrum plant bactericide ", and garlicin has noresidue, is difficult for producing resistance, do not have and cause change, teratogenesis, carinogenicity, cost is low, wide material sources and edible safety, has a wide range of applications at aspects such as human health care and medical treatment.
Garlicin (Alliiridum) is the general name of main bioactive ingredients in the garlic extract.The Chemical Composition of garlicin is set up jointly by more than 20 kind of volatility Containing Sulfur such as curing propylene, diallyl disulfide, three sulfuration dipropyl alkene, methyl propylene sulfide, methyl curing propylene.The cytolemma that disulfide in the garlicin and trithioether can see through germ enters in the tenuigenin, and the oxydasis that will contain sulfydryl is a cystine linkage, thereby suppresses cell fission, destroys the eubolism of germ and cancer cells.Studies show that in a large number that abroad garlicin has very strong restraining effect to many Gram-positives such as shigella flexneri, pasteurellosis bacillus, Corynebacterium diphtheriae, Staphylococcus albus, Bacillus proteus, Pseudomonas aeruginosa and negative bacteria and fungi such as Candida albicans.The structural formula of garlicin main component is:
Diallyl Thiosulfonate (allitridi) allicin (allicin) 4,5,9-trithiadodeca-1,6,11-triene 9-oxide (ajoene)
The fungi infestation of garlicin treatment diabetes urinary tract also has good result in addition, it is reported that total effective rate reaches more than 90%.Bulbus Allii extract can reduce fungi to oxygen absorption, slows down thalli growth, suppresses the synthetic of fat, protein and nucleic acid, and destroys membrane structure etc.The antimycotic mechanism of garlicin also may be to make protein inactivation by the oxidation to sulfydryl, with compound that contains sulfydryl such as halfcystine etc. competition takes place and suppresses; The effect of noncompetitive some enzyme of inhibition etc.
Polynite belongs to 2:1 type layered silicate, each unit cell is by carrying the layer of aluminum oxygen octahedra in the middle of two silicon-oxy tetrahedrons secretly, connect by public Sauerstoffatom between the two, this tetrahedron and octahedral close-packed structure make it have the crystal arrangement of high-sequential, and interfloor distance is approximately about 1nm.Interlayer is the Na of hydration

With 0.1～10 part of polynite, be dissolved in 2～500mL aqueous solution high-speed stirring dispersion treatment 20min～2 hours; 0.1～20 part of garlicin is added under 20～75 ℃ in the polynite colloidal solution that dispersion treatment is crossed, react 0.5h～5h down, obtain flocks at 20～75 ℃; With this sedimentation and filtration, washing; 60 ℃ of following vacuum-drying 24h, the solid of gained is functional montmorillonite-gallicin antibiotic complex after pulverizing;
Under 20～60 ℃, be scattered in 0～400 dispersion medium above-mentioned functions montmorillonite-gallicin antibiotic complex for 0.1～10 part, add 100 parts of polymkeric substance, ultra-sonic dispersion 0.5min～10min, make its thorough mixing, add 0～10 part of linking agent, 0～1 part of promotor is coated on the mould, places at least for 20～60 ℃ and promptly gets polymer-montmorillonoid-gallicin nano-antibacterial composite material in 0.2～24 hour;
Or with 0.1～10 part of above-mentioned functions montmorillonite-gallicin antibiotic complex and 100 parts of polymkeric substance thorough mixing, with twin screw extruder melt extrusion is vulcanized again, add 0～3 part of linking agent, moulding promptly gets polymer-montmorillonoid-gallicin nano-antibacterial composite material.
