Abstract
The invention relates to a bacteria-resistant coating which is characterized in that the coating material comprises at least one component of 0.01-20wt percent of inorganic bacteria-resistant agent or rare earth salt or rare earth oxide containing Ag-Zn, and the rest is other components. The invention has lasting bacteria resistance performance, wide bacteria resistance application range and provides prior materials with new healthy function and is beneficial to dramatically improving bacteria resistance performance level of traditional products.
Description
Technical field
The present invention relates to Materials science, provide especially a kind of use range wide, cheap, can give the antimicrobial coating of usual production surface with anti-microbial property.
Background technology
Along with The development in society and economy, the chance that people associate in public is more and more, and the probability that infects various germs is also increasing.In recent years, antibiotic notion and product are more and more paid close attention to by everybody.
In the prior art, antimicrobial coating is used comparatively widely, especially in being directed to various places of causing people's cross infection easily (as the surface of article such as the isolation railing of stair, call box, rubbish container and the road in public place or family kitchen articles for use and facility, foodstuffs industry relevant device and vessel, medicine equipment), the use of antimicrobial coating has brought huge value for people's production and life.
But there is following problem demanding prompt solution in existing antimicrobial coating: universality is poor, and is higher to base material requires, the preparation work complexity of coating, and the cost in coating material cost and the operation and maintenance process is higher.People wish to obtain that a kind of use range is wide, cheap, operation and maintenance is easy, good anti-bacterial effect, cost performance height, can give the novel antibacterial coating of usual production surface with anti-microbial property.
Metals such as silver, copper, zinc, titanium are one of human anti-biotic materials of being familiar with the earliest and utilizing.Before more than 4000 years, just with the sterilization of Copper Pot water storage, the soldier of ancient Greek in B.C. 5th century is filled with water directly to drink to ward off disease with silverware and propagates in army in India, and the Ancient Times in China imperial palace also adopts silverware as table ware.Metal ion all has strong or weak sterilizing ability, have according to the ordering of germ resistance size: Hg>Ag>Cd>Cu>Zn>Fe>Ni[is referring to reference 1:Fumiyasu Ishiguro, Takeshi Nishkawa, Ryozo Amano et al, Development of Nickel-ChromiumCoating with Antibacterial Performance, [J] .Materia Japan, 1999,38 (1): 64-66].But consider from the security aspect of metal ion, it is arranged as: Ag>Co>Ni>Al>Zn>Cu=Fe>Mn>Sn>Ba>Mg>Ca[is referring to reference 1 (as mentioned above) and reference 2:Ellis G.P, Luscombc D.K., Progress in MedicabieChemistry, 1994,81,351], most widely used in the present inorganic antibacterial material is Ag system, Cu system and Zn system.
