Abstract
An antibacterial anti-mildew paint is prepared from the basic paint and the metallic ions and nano inorganic substance, which have killing power to microbes through proportional mixing. Its advantages are high effect and no damage to human body.
Description
What technical field the present invention relates to is a kind of antibiotic fungus-resisting paint and preparation method thereof.
The background technology antibiotic fungus-resisting paint has the bacterial reproduction of reduction and pathophorous probability, removes the function to the trouble of environment disinfected from, can be widely used in various public places and household, office etc.The antibiotic paint that uses generally adopts the functional type additive of the organic anti-bacterial mould inhibitor of synthetic as antibiotic fungus-resisting paint at present, weaken the defective of antibacterial and antimildew function but this class antimildew and antibacterial agent ubiquity is volatile, timeliness weak point, narrow antimicrobial spectrum, bacterium are easy to generate resistance etc., with the harmful defective that waits damage to the environment of volatilization composition, cause antibiotic fungus-resisting paint not apply on a large scale.
Summary of the invention is at above-mentioned defective, the technical problem to be solved in the present invention: the one, how further to improve the environmental-protecting performance of antibiotic fungus-resisting paint; The 2nd, how further to improve the antibiotic of antibiotic fungus-resisting paint and mildew-resistant effect, and propose a kind of antibiotic fungus-resisting paint and preparation method thereof for this reason.
Antibiotic fungus-resisting paint provided by the invention by resin binder and various additive, comprises the antibacterial mildew inhibitor composition, and wherein antibacterial mildew inhibitor is a nano antibacterial mildew preventive, and content is 0.1 of coating gross weight---5%.
Antibiotic fungus-resisting paint provided by the invention, said nano antibacterial mildew preventive comprise the nano-powder that is loaded with heavy metal ion and the inorganic nanometer powder of antibacterial and mouldproof effect are arranged self.
Antibiotic fungus-resisting paint provided by the invention, the nano-powder that wherein is loaded with heavy metal ion are a kind ofly to be loaded with the heavy metal ion nano material in its many meso-hole structures.With the nano material is that matrix makes its heavy metal ion of enclosing antibacterial by absorption or ion-exchange method, as zinc, silver, copper etc.Because heavy metal ion is unstable with combining of nano material, it can play the antibacterial and mouldproof effect at leisure the place outside the molten effusion nano material from nano material.The mechanism one of its antibacterial and mouldproof effect is that the reduction potential of the heavy metal ion of high oxidation state is high because heavy metal ion has higher catalytic capability, is enough to make its surrounding space to produce atomic oxygen, and atomic oxygen has strong oxidizing property and can sterilize.The 2nd, some heavy metal ion can absorb the sulfydryl on the proteolytic enzyme in the microbe consumingly and (SH), combine with it rapidly, make the proteolytic enzyme loss of activity, cause microbial death.After microorganism was killed by metal ion, heavy metal ion was come by free in the microorganism corpse again, contacts with other microorganism again, carried out said process again and again and had persistence.
Antibiotic fungus-resisting paint provided by the invention, the surface that is loaded with the nano-powder of heavy metal ion also is coated with one deck organosilane or organosilicon, to prevent from that the heavy metal ion stripping from overrunning, to reach to make the effect of the nano-powder performance long-term antibacterial mildew-resistant that is loaded with heavy metal ion.
Antibiotic fungus-resisting paint provided by the invention wherein has the inorganic nanometer powder of antibacterial and mouldproof effect that nano zine oxide, nano-zinc borate or nano-titanium oxide etc. are arranged, and wherein the ore deposit of nano-titanium oxide is anatase octahedrite mutually.They are under the effect of ultraviolet ray and oxygen, the valence band electronics is launched into conduction band, electronics and hole have been formed, thereby generate the superoxide anion free radical with being adsorbed on its surperficial oxygen G﹠W effect, these free radicals have light and touch the ability of dividing microorganisms such as separating fungi in the gas, bacterium, mould.
Antibiotic fungus-resisting paint provided by the invention wherein also contains the dry film disinfectant of coating gross weight 0.1-3%.The dry film disinfectant has very high activity, make polymkeric substance charged, so be easy to by electrically opposite usually all kinds of Institute of Micro-biology absorption, thereby the splitting function that suppresses microorganism, make microorganism forfeiture reproductive performance, the film that adds polymer formation has stopped up the respiration channel of microorganism, and microorganism is choked to death rapidly.After dry film disinfectant and the inorganic nano antibacterial material synergy, antibiotic effect is up to more than 99.9%.
The preparation method of antibiotic fungus-resisting paint provided by the invention, be before preparing antibiotic fungus-resisting paint, earlier the color stuffing powder of the nano antibacterial mildew preventive of granularity between the 0.1-100 nanometer in antibiotic fungus-resisting paint to be put into high speed dispersor at normal temperatures with normal process, with 1000---1200 rev/mins rotating speed disperseed 0.5-1 hour, and sterilization material is evenly dispersed between the particle of color stuffing.
Antibiotic fungus-resisting paint provided by the invention, contain nano antibacterial mildew preventive, utilization has the heavy metal ion and the inorganic substance of kill capability to microorganism, their forms with nano material are joined in the antibiotic fungus-resisting paint, because employed nano antibacterial mildew preventive does not have volatility, there is not the possibility of the volatility harmful toxic matter that produces the injury human body.Characteristic because of nano material makes it not only have effective antibacterial and mouldproof effect again, reaches to purify air, and safeguards effects such as HUMAN HEALTH, more makes this effect have persistence.The preparation method of antibiotic fungus-resisting paint provided by the invention is dispersed in nano antibacterial mildew preventive in the antibiotic fungus-resisting paint full and uniformly, further guaranteed nano antibacterial mildew preventive after the antibiotic fungus-resisting paint film forming effectively, play a role all sidedly.The antibacterial and mouldproof effect of antibiotic fungus-resisting paint provided by the invention also can not cause microorganism that it is developed immunity to drugs in addition.
Embodiment embodiment one: with 25 parts of water, 0.3 part dispersion agent, 0.1 wetting agent, 0.2 part defoamer, 35 parts of color stuffings, 1 part of nano-titanium oxide, 3 parts of anion emission powder, in high speed dispersor with high speed dispersion half an hour under 1000 rev/mins the rotating speed, putting into three-roll grinder then grinds 2 times, make its granularity less than 75 μ m, ground slurry is put into dispersion machine, in dispersion machine, add 1.5 parts of film coalescence aid under 500 rev/mins the rotating speed, 24 parts of Emulsion acrylic resins and residue auxiliary agent, continue to stir after 30 minutes and add 0.2 portion of dry film disinfectant again, and accent pH=8.5, regulate viscosity at last to 90Ku, filter through vibratory screening apparatus and be product.
Embodiment two: with 25 parts of water, 0.2 part dispersion agent, part of auxiliary are put into high speed dispersor, add 32 parts of color stuffings, 0.2 part of nanometer is planted silver-colored anti-biotic material, 0.3 part of nano-zinc borate, it at rotating speed high speed dispersion after half an hour under 1100 rev/mins the condition, putting into three-roll grinder grinds 2 times, the slurry that grinding obtains is put into dispersion machine, at the ACRYLIC EMULSION and the residue auxiliary agent that add about 30 parts under 400 rev/mins the rotating speed, stir and add 1 portion of dry film disinfectant after 30 minutes, transfer pH=8, regulate viscosity at last, filter through vibratory screening apparatus and be product.
