Abstract
The invention discloses an antifouling paint. Non-metallic materials are added to the antifouling paint, so as to achieve a good antifouling effect. The non-metallic materials related to in the invention are nano carbon powder, a nano carbon tube, graphite powder and silicon powder. The final concentration ranges of these materials are 0.1-5.0% (W/V).
Description
Technical field
The invention belongs to biological technical field, be specifically related to a kind of antifouling paint, this antifouling paint is coated in shell and other body structure surfaces, stops harmful dirt organism to adhere to and grow to be immersed in water structure in seawater especially.
Background technology
Marine organisms bring the phenomenon of harm marine biofouling to aspects such as the performance of works and energy consumptions in the ocean engineering structure surface growth then.Not only to using the continental rise device of a large amount of seawater, and to the strand device, and more common be any object to permanent or Long contact time seawater, as hull and aquaculture rope, net cage and net, be all a significant problem.In fact, marine organisms as Crustaceans such as algae, shellfishes, adhere to and grow on the surface of exposure, this damaged normal Function and make device or object deteriorated.Particularly, for example, they can stop up the entrance that seawater enters valve, thereby reduce the water absorption capacity of the continental rise device that uses seawater, or they can reduce hull speed and increase the consumption of its fuel owing to adhering to described hull.
Scientist MIT found that some Nanosurface structure can effectively hinder typical stained microbial growth in 2012.Because the surface of nano particle can be very high, easily to be combined with other atoms, the bonding that nano particle and coating formation are stronger has increased compactness and the anti-ion permeability of coating.Usually the surface reduction electromotive force of nano material is high, produce atomic oxygen around very easily making it, in also can strong adsorption bacterial body endoenzyme protein molecular-SH ,-groups such as COOH and reaction with it, synthetic and the energy derive that has stoped protein, play germicidal action, thereby strengthen the antifouling ability of coating.Being used in combination also of nano material and non-nano material may produce better anti-fouling effect.
In world wide, the novel antifouling technology emerges in an endless stream at present.The final relatively type of environmental protection might be placed hope on the bionic surface micro nano structure.The performance of surface micronano structure depends on micro nano structure itself and prepares the material of this surface micronano structure (biopolymer, metal, nonmetal etc.).The technological layer that present people reach is also distant apart from the bionic surface micro nano structure.Such as the shark skin that certain natural anti-fouling effect is arranged possesses tens square metres of even areas of tens square metres, this surface has been covered with natural micro-nano surface structure.The surface also has a lot of problems if this surface nano-structure is used for ocean engineering structure, and such as not wear-resisting, not scratch resistance is put on the skin etc.If use metallic substance or other mechanically resistant materials to prepare and the similar surface nano-structure of shark skin, might solve simultaneously the problems such as antifouling and wear-resistant.Non-metallic material have higher bio-compatibility than metallic substance (especially heavy metal material) usually, and the occurrence degree that utilizes non-metallic material to suppress biodeterioration has vast potential for future development.
Summary of the invention
The object of the invention is to expand the technology of non-metallic material in biodeterioration inhibition field and use, a kind of novel antifouling paint is provided.
Antifouling paint of the present invention is added with the non-metallic material with protectiveness in its matrix, described non-metallic material are one or more in nano-carbon powder, CNT (carbon nano-tube), Graphite Powder 99, silica flour.
The interpolation concentration of described non-metallic material in matrix is 0.1-5.0% (W/V).
Described nano-carbon powder is the decolorizing carbon powder of median size 30 nanometers.
Described CNT (carbon nano-tube) is the hydroxylation double-wall carbon nano-tube, external diameter 2-4 nanometer.
Described Graphite Powder 99 particle diameter is less than 20 microns.
Described silica flour particle diameter is the 200-400 order.
The matrix of antifouling paint of the present invention can be a kind of in common antifouling varnish, rust-inhibiting paint or other priming paint, when non-metallic material are mixed in matrix, mixes extremely important.Need strong stirring, reach the purpose that mixes.Churning time is different according to different concentration, and high density is mixed and needed strong stirring, lower concentration to mix that stirring relaxes but churning time is long.Churning time is generally at 30 minutes to 3 hours.Coating after stirring is by spraying or smear the surface for the object construction thing.
The invention has the beneficial effects as follows, add the non-metallic material with protectiveness in the matrix of antifouling paint, reach the effect that checks or postpone the stained generation of engineering structure surface biological.These Material Additions after mixing, can form certain micro-nano surface structure in stromal surface in the matrix.Specific surface micronano structure and two the antifouling important factors of character formation that form the material of these surface tissues itself.By the interaction of above-mentioned two factors and the fouling organism young, perhaps and the interaction between early stage stained microorganism, finally reduce adhering to or growing of Macro-fouling Organisms (as barnacle and the oyster) young.Several non-metallic material market purchase price that the present invention relates to is cheaper or moderate, and not having obviously increases cost to the preparation of antifouling paint.in addition, the ability that studies show that non-metallic material initiation transgenation is generally obvious lowly next than metallic substance, thereby possess better Environmental Safety and (see two pieces of reference: (1) NanoPCR Observation:Different levels of DNA replication fidelity in nanoparticles-enhanced polymerase chain reactions. Cenchao Shen, Wenjuan Yang, Qiaoli Ji, Hisaji Maki, Anjie Dong, Zhizhou Zhang*, Nanotechnology, 20 (2009) 455103, (2) A potential useful method for calculating relative safety index of nanoparticles.
