Face forms bacterial plaque, so that coating is lost adhesive force, or even cause coating shedding, influences the defencive function and decorative effect of coating.Separately
On the one hand, the bacterial plaque of coating surface can infect disease, cause high risks to human health.And antimicrobial coating can be to avoid above-mentioned
Situation occurs.
The antimicrobial coating of metal surface is formed by physico-chemical process on surface by adding antibacterial agent in the solution
Antimicrobial coating.Currently, common antibacterial agent mainly has inorganic antiseptic, organic antibacterial agent and natural antibacterial agent three big in coating
Class.But these anti-biotic materials have different problems, such as limited chemical stability, the local inflammation as caused by material composition
The features such as reaction and coating, which lack, controls release dynamics, cytotoxicity, thermal stability is poor.Iodine is one kind of thyroid hormone
Ingredient is most important element needed for all organisms.Iodine has proved to be a kind of wide spectrum, efficiently, quick-acting bactericide, to people
Body is harmless.Iodine has been widely used as a kind of bactericidal disinfectant material, but the antimicrobial coating as metal material surface
Research and application are also fewer.Toshiharu professor Shirai of Japanese Kanazawa university is to Titanium Alloy Screw surface
It carries out anodized generation perforated membrane and is subsequently filled the iodine coating with antibacterial action, there is good antibacterial effect.So
And the process requirement first carries out anodized to metal surface, complex process is expensive.The present invention metal surface into
Row directly covers iodine, and simple process is low in cost, works well.
Summary of the invention
In order to solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of broad-spectrum antiseptic, antibiotic rate it is high
Metal surface antimicrobial coating and preparation method thereof, it is intended to improve the anti-microbial property of metal material.
In order to realize above-mentioned technical purpose, the technical solution of the present invention is as follows:
1) by metal surface be polishing to surface it is smooth after with EtOH Sonicate clean 1-30min, then in HF and HNO3Mixture
Middle progress chemical polishing (HF and HNO3Volume ratio=1:3) 1-20min；
2) a certain amount of iodine substance is weighed, is dissolved in deionized water, configuration concentration is the solution of 500-10000ppm, stirs 1-
30min obtains electrolyte；
3) it using metal as anode, using platinized platinum as cathode, keeps between cathode anode at a distance of 2cm, using above-mentioned solution as electrolyte, water
Bath control constant temperature carries out iodine deposition；
4) obtained sample ultrasonic cleaning post package is saved；
The step 1) metal includes iron, stainless steel, titanium or titanium alloy, aluminium alloy, magnesium alloy, cobalt-base alloys, nickel alloy, tantalum,
Any one in niobium, zirconium-based metallic material；
The step 2 includes povidone iodine, HIO containing iodine compound3、KIO3、KIO4, the soluble iodides such as KI；
The step 3) water-bath controls 5-80 DEG C of constant temperature；
The step 3) deposition current is 20-200mA, time 10-120min；
Further, above-mentioned preparation method is applied to prepare medical apparatus and instruments, medical instrument, implant material, biology in fact
Test vessel, in food preservation sterilizable material.
The study found that content of iodine has a significant impact to the anti-microbial property of sample in coating.The present invention uses above-mentioned technical side
Case is controlled using Biodine as electrolyte by condition, is prepared for one layer of uniform iodine coating in metal surface.
The present invention has the advantages that
(1) preparation technology of coating is simple, and the time is short；
(2) coating uniform and content of iodine height；
(3) good anti-bacterial effect, antibiotic rate can achieve 90% or more.
