Description
Technical field
The present invention relates to a kind of nontoxic inorganic anti-rust, the manufacture method and the overlay thereof of anti-fouling ship bottom paint, this coating as carrier, is suitable for preventing getting rusty and preventing benthic adhering to of boats and ships, subbottom structure thing etc. with modified water glass.
Background technology
In the past as preventing that epibiota is attached to the method for boats and ships, subbottom structure thing etc. and the part of contact with sea water, what adopt is to add the big inorganic and organic toxic agent of toxicity and make it the method for slow stripping in the seawater in antifouling paint, but, therefore can't accomplish according to season, tsunami (stream) and the suitable antifouling effect of change of water quality performance owing to the dissolution rate that can not regulate as the toxic agent of antifouling effective constituent.
Under normal conditions, the toxic agent of a threshold quantity can only be contained in the antifouling paint, therefore approximately primary coating will be carried out in per 2 years; and because the stripping of toxic agent; can cause very serious pollution to seawater, therefore serious to the public hazards in marine site, aspect the global environment protection also be a bigger problem.A kind of anticorrosion nontoxicity ship-bottom paint is disclosed in English Patent GB02284822 (nineteen ninety-five), in European patent EP 0881269 (1998), disclose can make at normal temperatures paint solidification, can be used for preventing hull or the contaminated antifouling paint of subbottom structure thing, in the open WO9727751 (1997) of Japanese Patent, the material that is used for the anti-organic pollution of sealing as the antifouling paint use of fishing net and hull bottom is disclosed in addition.
Yet these are not complete inanimate matter coating, are the suitable mixtures of organic system and inorganic system.
In addition, as water glass is the solidifying agent of coating, known have phosphoric acid and as phosphatic polyphosphoric acid silicon, titanium phosphate with as the calcium oxide of metal oxide, aluminum oxide etc., and glass fibre, carbon fiber have been proposed as its strengthening agent, in addition a lot of relevant technology have also been proposed, but wherein all do not solve the essence defective of water glass class coating, promptly lack water tolerance and flexible problem.
In addition, proposed by solving the scheme of antirust antifouling problem with contact nobody with special functional the filming of inorganic silicic acid salt formation.
Recently, world's public hazards prevent that international body from just preventing that the marine site public hazards from having proposed to forbid the scheme of toxic antifouling paint, and have taked legal measure, but effective nontoxicity antifouling paint also do not occur so far.
