Description
Technical field
The present invention relates to a kind of preparation method of antibiotic antistatic coating.
Background technology
The common traditional coating in market is natural resin or synthetic resins is base-material, then add various pigment, various filler, the machined manufacture of auxiliary agent solvent form.Some resin wear no resistance and in environment for use, there is friction in some, use and usually cause paint film to wear and tear, and lose function; On the other hand, because macromolecular material mostly is Ins. ulative material, in dry environment, usually can produce electrostatic, bring larger harm, even dangerous; Again because environment hygrothermal environment etc. can cause the enzyme flora of paint film raw.
Summary of the invention
The object of this invention is to provide a kind of antibacterial and coating that is anti-electrostatic of having concurrently, polyaniline nano fiber and the carbon nanotube of external sheath silver has been prepared by spray method, and using it as the conductive component of coating, obtain the coating composition with excellent antibacterial and antistatic performance.
The object of the invention is to be achieved through the following technical solutions:
A preparation method for antibiotic antistatic coating, is characterized in that adopting following method preparation:
A) preparation of silver-colored carbon nanotube is carried: in the silver nitrate solution of 0.001mol/L, add aqueous sodium hydroxide solution, weak ammonia is instilled after stirring, after dissolving to be precipitated, obtain silver ammino solution, the silver ammino solution obtained evenly is sprayed to the surface of carbon nanotube powder in the mode of spraying, after the complete wetting of carbon nanotube powder surface, adopts the mode of identical spraying to be sprayed to carbon nano tube surface in the acetaldehyde measured rapidly, leave standstill 1 minute, obtain the carbon nanotube of outside surface load silver;
B) preparation of silver-colored polyaniline nano fiber is carried: in the silver nitrate solution of 0.001mol/L, add aqueous sodium hydroxide solution, weak ammonia is instilled after stirring, after dissolving to be precipitated, obtain silver ammino solution, the silver ammino solution obtained evenly is sprayed to the surface of the polyaniline nano fiber that diameter is 60-80nm in the mode of spraying, after the surperficial complete wetting of polyaniline nano fiber powder, the mode of identical spraying is adopted to be sprayed to polyaniline nano fiber surface in the acetaldehyde measured rapidly, leave standstill 1 minute, obtain the polyaniline nano fiber of outside surface load silver;
C) preparation of coating: year silver-colored polyaniline nano fiber 20 weight part, solvent 70 weight part that carry silver-colored carbon nanotube 20 weight part, step b) acquisition of getting Emulsion acrylic resin 40 weight part, step a) acquisition, mix and blend 30 minutes, then add dispersion agent 3 weight part, flow agent 3 weight part and defoamer 2 weight part, abundant stirring 30 minutes, obtains antibiotic antistatic coating.
The process of described step a) and spraying load silver b) is carried out at 40 DEG C.
The stir speed (S.S.) of described step c) is 400 revs/min.
beneficial effect of the present invention
Polyaniline nano fiber has good electroconductibility and stability, and the polyaniline of nanofibrous structures, compared with the polyaniline of other structure, has higher electric conductivity; Carbon nanotube has good mechanical property and electric property simultaneously.Coating of the present invention employs the polyaniline nano fiber of area load silver, the carbon nanotube of mating surface load silver simultaneously, not only increase the electroconductibility of coating, make coating have good germ resistance and rub resistance simultaneously, adopt the mode load silver of special spraying, make silver almost load on the surface of polyaniline nano fiber and carbon nanotube, while increase germ resistance and electroconductibility, greatly reduce preparation cost.
