Abstract
The invention discloses a preparation method of special chitosan-base nano silver for antibacterial paints, belonging to the technical field of antimicrobial agent preparation. The shrimp shells are used as the raw material to prepare chitin, and the chitin is subjected to deacetylation reaction to obtain the chitosan; by using the polyhydroxy characteristic of the chitosan, the chitosan is added in the process of preparing nano silver from silver nitrate and hydrazine hydrate by precipitation, and the precipitated nano silver particles and hydroxyls on the chitosan surface generate chemical bonds and physical adsorption, so that the nano silver particles are uniformly distributed on the chitosan surface, thereby avoiding the van der waals force interaction among nanoparticles, and further solving the problem of high aggregation tendency of the nano silver; and the nano-silver-carried chitosan matrix has favorable compatibility and dispersity, thereby solving the problem of insufficient nano silver dispersion uniformity in the traditional antibacterial paint. Thus, the method has broad market prospects.
Description
Technical field
The invention discloses the preparation method of the special chitosan-based nanometer silver of a kind of antibiotic paint, belong to antibacterial technology of preparing neck
Territory.
Background technology
China's rapid economic development in recent years, city-building in all parts of the country is also into a brand-new developmental stage, and this indicates
Building industry more significantly as the status of pillar industry in national economy.Associated building coating industry is in height too
The period that speed increases.Adding up according to relevant departments, Architectural Paint in China output value proportion in whole coatings industry reaches
More than 40%.Along with mankind's attention to self health status, the living environment that we are together morning and night the most increasingly receives publicity.
One investigation of living environment microbes contamination shows: the antibacterial sum in rural area is 138.94cfu/cm2, cities and towns are
72.10cfu/cm2.The pollution that in visible living environment, microorganism causes is very important.Antibiotic paint can directly be painted on
On various materials, receiving much concern because it is easy to use, exploitation has the direction that the coating of antibacterial functions is coatings industry development
One of.
Chitosan is a kind of alkalescence high-molecular biologic polysaccharide material, is a kind of functional reproducible biomaterial, by first
Shell element is prepared by deacetylation, has good biocompatibility and degradability, and its Chemical Physics stable performance is nontoxic
Harmless odorless, has good affinity with organism, also has health-care effect to human body.Owing to chitosan molecule having ammonia
Base, hydroxy functional group, can occur multiple chemical reaction (such as: can be formed with titanium oxide divide with nano-silver ionic generation complex reaction
Hydrogen bond etc. between son).
Antibiotic paint mainly possesses following several effect: 1, reduce cross infection probability, further the biography occurred frequently to burst
The control effect caught an illness: exceed a lot than general private place, if obtaining not with pathogenic bacteria density public place on body of wall in air
Control to effective, cause cross infection easily.Use antibiotic paint, can effectively purify air in institute, be substantially reduced intersection sense
Dye probability.2, purification air is help: just finishing or newly-built public place inevitably to introduce some band pollution elements
Finishing material and office equipment, not only self environmental protection of diatom ooze antibiotic paint, TVOC, the first dispelling in air can be help simultaneously
An aromatic plant metioned in ancient books, benzene, at the shortest time internal diabetes depollution, really realizing completion can come into operation.Antibiotic paint mainly adds in coating
Enter various antibacterial, thus be made for antibiotic paint.At present, coating antibacterial mainly has natural antibacterial agent, organic antibacterial agent
With inorganic antiseptic three major types.Antibiotic paint on market is many directly to add nanometer silver and/or titanium dioxide, to reach antibacterial
Effect.But nanometer silver is not sufficiently stable in coating, is susceptible to reunite, and dispersion is uniform and relatively costly not.And nanometer two
Titanium oxide needs just can effectively sterilize by ultraviolet light, does not have universality, and market prospect is poor.
Summary of the invention
The technical problem that present invention mainly solves: many directly to add nanometer silver to reach for antibiotic paint in the market
Antibacterial effect, but nanometer silver is not sufficiently stable in coating, is susceptible to reunite, and the uniform not defect of dispersion, it is provided that one
Kind prepare chitin with Crusta Penaeus seu Panulirus for raw material, then carry out deacetylation and prepare chitosan, utilize the polyhydroxy characteristic of chitosan,
During silver nitrate and hydrazine hydrate precipitation prepare nanometer silver, add chitosan, make nano silver particles and the chitosan table of precipitation
Face hydroxyl produces chemical bond and physical absorption, make nano silver particles be arranged in chitosan surface uniformly, it is to avoid nanoparticle
Between the interaction of Van der Waals force, thus solve the defect that nanometer silver is susceptible to reunite, and the shell of loading nano silvery gather
Glycosyl body has excellent compatibility and dispersibility, solves again the uniform not problem of nanometer silver dispersion in tradition antibiotic paint,
Have broad application prospects.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:

Enter in Soxhlet extraction device, add its volume 3～5 times of dehydrated alcohol extract backflow 6～8h isolated filtering residues at 70～80 DEG C,
Gained filtering residue is proceeded in fermentation tank, adds filtering residue gross mass 3～the neutral protease of 5% and the isopyknic distilled water of filtering residue,
Enzymolysis 6～9h under room temperature；
(2) treating that enzymolysis terminates, enzymatic hydrolysate is moved into beaker, adding 1～2L concentration in beaker is 0.2mol/L hydrochloric acid solution,
It is placed on shaking table vibration steeped overnight, removes mineral salt impurity, obtain filtering residue after filtration and put into oven drying, obtaining carapace
Element；
(3) chitin obtained above is immersed its volume 10～15 times of mass concentrations are 30～40% in sodium hydroxide solution
Mixed liquor, proceeds to mixed liquor in the there-necked flask with reflux, is heated to 75～85 DEG C, is incubated back flow reaction 12
～20h, reactant liquor horizontal centrifuge is centrifuged 10～15min with 4000～5000r/min rotating speeds, isolated precipitates, and puts
Enter baking oven at 40～50 DEG C, be dried 3～5h, obtain chitosan, standby；
(4) concentration is 0.2mol/L silver nitrate solution and equal-volume dehydrated alcohol mixes to obtain base fluid, then by hydrazine hydrate and anhydrous
Ethanol is that 1:1 mixes to obtain dropping liquid by solid-to-liquid ratio, adds in base fluid for 2:1 by dropping liquid the most by volume, puts into Under Ultrasonic Vibration
Swing instrument and react 50～60min with 200～300W oscillation of powers, obtain black suspension；
(5) in above-mentioned black suspension, add its gross mass 5～10% standby chitosan, with magnetic stirrer with 300～
Proceed to, in 4～6 DEG C of ice-water baths, staticly settle overnight, finally filter to obtain filtering residue, put after 400r/min rotating speed stirring mixing 1～2h
Enter after baking oven is dried 2～3h at 40～50 DEG C and i.e. obtain chitosan-based nanometer silver.
The application process of the present invention is: the chitosan-based nanometer silver that the present invention is prepared by addition be 2～4% add be coated with
In material, after mix homogeneously, make antibiotic paint, can directly brush on various base materials, play antibacterial and bactericidal action.After testing,
The antibiotic paint using the present invention to prepare has potent bactericidal action (to the microorganism such as escherichia coli, gold-coloured staphylococci
Sterilizing rate reaches 99.9%, and bactericidal effect not light and the impact of water), self-cleaning performance is the most prominent, this novel using
After coating application indoor wall 12～18h, indoor harmful gas can be made to decompose 60～80%, after 48h, harmful gas is all decomposed.
