Abstract
In the preparing method, nanoantibiotic powder is prepared by connecting germicide covalency of quaternary ammoium salt or quaternary phosphorus salt polymer on nanopowder through covalent decoration method in utilizing nanopowder with functional perssad of antibiosis, prepared powder is disposed to be antibiotic solution containing 0.01-0.1% nanogermicide and then the colution is added into four sorts of film forming materials for making film with conventional process.
Description
Technical field:
The present invention relates to the preparation method of a kind of nano-antibacterial (being coated with) film.
Technical background:
The preparation method of existing antibiotic (being coated with) film adopts organic antibacterial agent such as organic acid, antibacterial peptide, biological enzyme etc. to combine with mould material such as polyose, protein, Mierocrystalline cellulose and derivatives class, synthetic macromolecule etc., utilizes the differing molecular interphase interaction to form antibiotic (being coated with) film with porous network structure.The problem of this class antibiotic (being coated with) film is, antiseptic-germicide is insecure with combining of mould material, break away from easily, and the easy inactivation of antiseptic-germicide, inefficacy and do not reach antibiotic purpose.
Summary of the invention:
The objective of the invention is: adopt nano-powder with antibacterial group, utilize the big specific surface area and the strong absorption property of nano-powder, the antibacterial group is adhered to and be embedded in the mould material, thereby make mould material have broad-spectrum antimicrobial, efficient, long-acting and stable antibacterial.
The present invention is achieved in that and utilizes the nano-powder with antibacterial group, with Chinese patent application 03117920.7 disclosed covalent modification method, quaternary ammonium salt or quaternary alkylphosphonium salt polymkeric substance antiseptic-germicide is covalently bound to nano-powder and the antiseptic nano powder that obtains, the nano-powder antiseptic-germicide is pressed different needs, be configured to contain the antimicrobial of nano antibacterial agent 0.01～0.1% concentration, joining then can film forming polyose, protein-based, Mierocrystalline cellulose and derivatives class thereof, in the synthetic polymeric kind film material, frequent regulation membrane process system film, or directly material surface routinely coating process film, form antibiotic (being coated with) film.
Described polyose mould material is meant can film forming polyose such as starch, glucomannan, alginates, and itself and antiseptic nano powder are mixed into and contain nano antibacterial agent 0.01～0.1% concentration in the film-forming soln.
Described protein-based mould material is meant can be film forming protein-based as gelatin, zein, whey-protein, and itself and antiseptic nano powder are mixed into and contain nano antibacterial agent 0.01～0.1% concentration in the film-forming soln.
Described Mierocrystalline cellulose and derivatives class mould material thereof are meant can film forming Mierocrystalline cellulose and derivatives class such as carboxymethyl cellulose, cellulose acetate, Natvosol, Microcrystalline Cellulose, and itself and antiseptic nano powder are mixed into and contain nano antibacterial agent 0.01～0.1% concentration in the film-forming soln.
Described synthetic polymeric kind film material is meant can film forming synthetic macromolecule class such as polyvinyl alcohol, sodium polyacrylate, polyvinylpyrrolidone, and itself and antiseptic nano powder are mixed into and contain nano antibacterial agent 0.01～0.1% concentration in the film-forming soln.
The present invention compared with prior art has following advantage:
1. adopt covalently bound quaternary ammonium salt or quaternary alkylphosphonium salt polymkeric substance antiseptic-germicide, have broad spectrum antibacterial.Utilizing nano-powder is antibiotic carrier, and antibiotic effect is lasting, efficient, stable.
The present invention prepare the method for antibiotic (being coated with) film be mould material and antimicrobial powder in varing proportions with the concentration uniform mixing, often regulation membrane process or coating process carry out the film forming processing, technology is simple, does not change original technology, and the performance of antibiotic (being coated with) film each side that forms all obviously improves.
