Description
Technical field
The present invention relates to the preparation method of biological antifouling drag reduction coating, the antifouling drag reduction coating of this biology; And the antifouling drag reduction processing method on surface; More specifically; The preparation method who relates to a kind of antifouling drag reduction composite coating of nontoxic biological that contains luminescent powder, the antifouling drag reduction composite coating of nontoxic biological that this kind contains luminescent powder, and the antifouling drag reduction composite coating of the nontoxic biological that adopts this to contain luminescent powder carries out the method that the antifouling drag reduction of substrate surface is handled.
Background technology
Under water, on the basal surface of various matrixes, adhere to and growth, the breeding of various organic life entities (for example microorganism, sea lettuce, barnacle or the like) all bring many drawbacks, and this phenomenon is referred to as biodeterioration.For example the biodeterioration in the marine environment can cause that the naval vessels energy consumption increases, the speed of a ship or plane reduces, efficient reduces, and the increasing the weight of or the like of various corrosion.No matter from civilian, commercial or military, the marine anti-pollution problem all is important topics of ocean engineering.Industry is a huge obstacle to marime fouling as far as Yu Haiyang, so the various countries scholar all is devoted to study and can realizes effectively antifouling coating.On the basis of nonpolluting coating, the technology through the drag reduction coating can better realize raising the efficiency, practices thrift earth resource and improve problem of environmental pollution.
To the requirement of present marine anti-pollution and drag reduction aspect, present drag reduction means mainly comprise the low-surface-energy super-hydrophobic coat of imitative lotus leaf, the flexible coating of imitative dolphin, and the polymeric coating layer of imitative mucus or the like.Yet the prerequisite of these drag reduction coatings applications Yu Haiyang systems is to need good anti-fouling effect.And antifouling to marine organisms, present main countermeasure comprises chemical preservation method, physics anti-fouling method and biological anti-fouling method.Wherein chemical method comprises the nonpolluting coating that adopts contact-type, lysotype and polishing type certainly, wherein the most effectively from tributyl tin (TBT) coating of polishing type, yet because it has very big harm to the environment aspect, is forbidden by international legislation at present.Thereby derived various other chemistry (poisoning) anti-fouling methods, for example replace and contain tin coating or the like with the compound of the compound of copper, zinc.Yet all kinds of chemical methodes always produce harmful effect to environment, and it is extremely important therefore studying nontoxic and effective wide spectrum antifouling.For this reason, the various countries scholar hopes through low-surface-energy material to make attachment under flow action, be rinsed on the one hand from the material angle; On the one hand from physical angle, carry out antifoulingly through modes such as electrolysis or radiation, or the physical characteristic through changing material surface such as roughness, surface topography, hydrophobicity, zeta current potential etc. carry out antifouling; Last aspect is from biological angle, thereby purify various biological metabolites or enzyme suppress biodeterioration.At present, physical method still rests on laboratory stage, and lacks relevant theoretical direction.Though and biological method such as enzymatic isolation method have more antifouling potentiality, it still lacks the experimental evidence of application facet.Therefore, nontoxic and effective antifouling means of wide spectrum wait research and development on the desirable meaning.
Drag reduction aspect under water, main countermeasure comprises submissive wall drag reduction, hydrophobic surface drag reduction at present, rib drag reduction, retinue wave surface drag reduction etc.Yet most drag reduction technology or be limited by the traditional processing means, or only limit to the service condition of low flow velocity and fluid channel, all can't obtain the wide industrial application.Therefore, processing technology is simple, and with low cost and effective drag reduction means wait research and development.
