A sea anti-soil coating material with low cost, simple preparation, easy popularizing and a process for preparation comprise neem and boiled wood oil, whose volume ration is that neem : boiled wood oil =1: (2-200). The process comprises adding neem in boiled wood oil, evenly stirring, and getting ea anti-soil coating material.
Description
Technical field
The present invention relates to a kind of antifouling paint, especially relate to and a kind ofly being prepared from, be used to prevent that marine organisms are at the marine antifouling coating that adheres to and grow on marine artificial facility surface and preparation method thereof by nimbin and boiled wood oil.
Background technology
The surface of naval vessel, floating terminal, offshore platform, undersea cable, buoy and submarine mine, the marine artificial facilities such as power station cooling duct and net cage for sea farming that border on the sea is usually adhered to by marine fouling organisms such as algae, sponge, hydra, outer anus animal, imperial cyprid, mussels, barnacle and Ascidians, this can increase ship resistance, blocking pipe and netting gear, acceleration metallic corrosion, increase Offshore Units weight etc., and ocean military affairs, sea transport, oceanographic engineering and sea farming are brought about great losses.Solve at present in the method for marine biofouling, safe and reliable, convenient economic, effective means is the brushing marine antifouling coating.General marine antifouling coating is by base-material, stain control agent, color stuffing and solvent composition, wherein color stuffing mainly plays the outward appearance effect of covering and colouration, solvent is generally the volatile organic liquid of dissolving base-material, and its volatilization not only causes topsoil, the health that endangers the workmen simultaneously.Integral part most important in the marine antifouling coating, core is base-material and stain control agent.Base-material has rosin, coal tar pitch, chlorinated rubber and acrylate etc.Stain control agent then is the part to preventing that marine biofouling from playing a crucial role in the antifouling paint, heavy metals such as copper, tin, mercury, lead are the most frequently used stain control agents, particularly fish and shellfish have very strong toxicity equally but the particularly the most frequently used organotin of these stain control agents is to other marine organisms, the severe contamination ocean environment, and they also can enter human body by food chain, threaten human beings'health.Therefore, International Maritime Organizaton has issued that in 1999 the organotin stain control agent uses the draft of final term, and the final time limit of service that regulation contains the organotin antifouling paint is on January 1st, 2008." China Ocean Agenda 21 " that China National Bureau of Oceanography formulates also clearly proposes to develop pollution-free ocean anticorrosion and antifouling technology.Therefore, the environment-friendly type marine antifouling coating that does not contain or only contain a small amount of above-mentioned objectionable impurities (heavy metal stain control agent and organic volatile solvent) becomes the main developing direction of marine antifouling coating.At present people seek the natural product with antifouling activity from biology, and as nontoxic stain control agent, but the common complex structure of these natural product stain control agents is difficult to synthetic, costs an arm and a leg with it, and cost is very high, has hindered large-scale production and application.
Publication number be the application for a patent for invention of CN1216680 disclose a kind of by the coating diphenyl diketone suppress the method that marine organisms grow on marine structure.These compounds can directly be added in the marine structure in manufacturing processed, directly are coated on the buildings, or are applied on the buildings with coating.
Publication number is that the application for a patent for invention of CN1189293 discloses a kind of pyridazinone as marine antifoulant, be dihydropyridazinone and pyridazinone compound are applied on the marine structure or in.These compounds can directly mix marine structure at production period, directly are applied to works or the mode by coating is applied to works.
Publication number is that the application for a patent for invention of CN1299589 discloses a kind of 5-anilide base as biocide and marine antifoulant-chloro alkyl thiazole.
Summary of the invention
The objective of the invention is at existing antifouling paint be difficult to synthetic, cost an arm and a leg, cost is than problems such as height, and marine antifouling coating that a kind of cost is low, preparation is simple and easy, product is easy to promote and preparation method thereof is provided.
Marine antifouling coating of the present invention comprises nimbin and boiled wood oil, and by volume, nimbin: boiled wood oil is 1: (2～200).
The preparation method of marine antifouling coating of the present invention adds nimbin in the boiled wood oil, stirs, and promptly gets marine antifouling coating.
The base-material boiled wood oil that marine antifouling coating of the present invention adopted is a kind of good siccative oil, is processed by traditional technology by the living tung oil that gets from the squeezing of tung oil tree fruit.Boiled wood oil is the special product of China, and permanent use history is arranged, and is widely used in furniture, building, oilcloth, umbrella and lacquer skill.Boiled wood oil is as the high edible vegetable oil of a kind of viscosity, can transfer rarely during use without solvent, better hardness and gloss arranged, anti-water, alkaline-resisting behind the conjunctiva.These characteristics of boiled wood oil show that it can be used as the base-material of marine antifouling coating, and can use solvent, and this has just eliminated the pollution that deleterious organic solvent volatilization is caused.
Compare with existing antifouling paint, the present invention has following outstanding advantage:
1) antifouling property is remarkable, show through experiment detection and the test of real tidal land cloth, and under lower concentration the tool anti-fouling effect.
2) stain control agent is a natural active matter, does not destroy natural, ecological, and does not contain solvent in this antifouling paint, and is free from environmental pollution.
3) only contain nimbin and two components of boiled wood oil owing to marine antifouling coating of the present invention, and confirm that through test nimbin has good compatibility in boiled wood oil, therefore needed preparation technology is simpler.
4) production cost is low, is suitable for scale operation and application, and nimbin and boiled wood oil be scale operation all, can buy on market, and is cheap.
5) can be widely used in naval vessel, floating terminal, offshore platform, undersea cable, buoy and submarine mine, the fields such as power station cooling duct and net cage for sea farming of bordering on the sea.
