Above-mentioned film-forming resin is the vinyl resin that the molecular formula directly bought from the market meets above-mentioned general formula (I), is vinyl resin commonly used in the paint field, need not to specify.
Above-mentioned shell-crosslinked silicone oil microcapsule are the low-energy liquid microcapsule, adopt following method preparation: select for use situ aggregation method in oil-in-water system, to carry out, the concrete preparation process of microcapsule is routine techniques preparation in the industry, and roughly step is following:
(1) with sorbitan fatty acid ester (Span) and two kinds of surfactant compounds of polysorbate (Tween) as emulsifying agent; With each component emulsifying agent, water, silicone oil (core) etc. of preparation silicone oil emulsion at 70 ℃ of following high-speed stirring emulsification pretreatments; And the consumption that passes through WOR example and emulsifying agent is regulated the silicone oil emulsion particle grain size; Obtain silicone oil content and be 10%~20%, sorbitan fatty acid ester content is 2%~6%, polysorbate content is 2%~6%, all the other are the oil-in-water of water (O/W) type silicone oil emulsion, above-mentioned each component concentration is a mass percent;
(2) with the silicone oil emulsion of step (1) gained and the monomeric aqueous solution of water-soluble polymer; Wherein the quality proportioning between monomer and the water is 5%~10% in the monomeric aqueous solution of water-soluble polymer; Monomer is a kind of in the monomer of polymkeric substance such as SEPIGEL 305, ROHM, HPMA; And then in said mixture, add linking agent, addition be water in the monomeric aqueous solution of above-mentioned water-soluble polymer quality 0.1%~1%, utilizing the method for in-situ polymerization is 40 ℃~80 ℃ in temperature of reaction; Time is the shell (wall material) that generates a cross-linked polymer under 4~8 hours conditions at silicone oil emulsion particulate surface in situ; This shell coats the silicone oil emulsion particle wherein, through the thickness of monomeric concentration adjustment shell, and the degree of crosslinking of the concentration adjustment shell through linking agent; Gained suspension-s obtains the silicone oil microcapsule with YLENE, absolute ethyl alcohol and distilled water wash, filtration; Quality proportioning between the monomeric aqueous solution of above-mentioned silicone oil emulsion and water-soluble polymer is 1: 1~5.
Above-mentioned steps 1~2 is all carried out under normal pressure.
In the above-mentioned shell-crosslinked silicone oil microcapsule original position polymerization, the core of shell-crosslinked silicone oil microcapsule is that the silicone oil in the shell-crosslinked silicone oil microcapsule is one or more in methyl-silicone oil, hydroxy silicon oil, amido silicon oil, the alkoxyl group silicone oil.
The wall material of above-mentioned shell-crosslinked silicone oil microcapsule be shell be can be in water wherein a kind of such as swollen SEPIGEL 305, ROHM, HPMA; Linking agent is meant the linking agent of above-mentioned SEPIGEL 305, ROHM, HPMA, is preferably diene class linking agents such as methylene-bisacrylamide, like N,N methylene bis acrylamide.
Through the shell-crosslinked silicone oil microcapsule that above two steps obtain, the degree of crosslinking of its particle size, wall thickness, shell is all controlled, can regulate the rate of release of silicone oil in seawater through above three factors and the content of microcapsule in coating.
Above-mentioned softening agent is phthalic ester [like DOP (DOP), Witcizer 300 (DBP)], fatty group dibasic acid [like Octyl adipate (DOA), dioctyl sebacate (DOS)], SULPHOSUCCINIC ACID ESTER [like Tritolyl Phosphate (TCP), phosphate toluene diphenyl ester (CDP)], epoxy compounds (as: epoxidised soybean oil, epoxyoleic acid butyl ester), Reoplex (as: hexanodioic acid Ucar 35 polyester), benzene polyacid ester (as: 1; 2,4-triisooctyl trimellitate), a kind of in chloro-plasticizer (as: clorafin, pentachloro-methyl stearate), alkyl sulfonic ester, polyol ester etc.
Above-mentioned skimmer adopts modified dimethyl polysiloxane class (like epoxy group(ing) modified dimethyl polysiloxane, polyether-modified YSR 3286 BYK300 etc.) or polyethers (like PPE type polyether antifoam agent) or higher alcohols (like DP592 etc.) skimmer.
Above-mentioned color stuffing is selected one or more in process white, white titanium pigment, light calcium carbonate, iron oxide red, zinc oxide, sepiolite, aluminium triphosphate, the carbon black for use.
Above-mentioned solvent is selected at least a in methylethylketone, acetone, pimelinketone, Virahol, propyl carbinol, methyl acetate, ETHYLE ACETATE, butylacetate, the YLENE for use.
Microcapsule content is controlled between 7.0~18.0%, is lower than the decline that this content can cause this coating antifouling property, is higher than this content and then causes unnecessary waste of material, and cost increases, and is unfavorable for applying of this technology.The interpolation of color stuffing gives antifouling paint enough mechanical propertys, prevents that coating from producing phenomenons such as ftractureing, come off, and being added with of various auxiliary agents is beneficial to antifouling paint and forms uniform and stable dispersion system.
Environment-friendly marine antifouling coating provided by the invention compared with prior art, has the following advantages:
1, the present invention is stain control agent with the low-energy liquid; And it is carried out micro encapsulation handle the microcapsule (shell-crosslinked silicone oil microcapsule) that obtained wrapping up low-energy liquid; Itself and film-forming resin, softening agent, skimmer, color stuffing and solvent are constituted low-energy liquid slow release type antifouling paint jointly; Utilize low-energy liquid to suppress biodeterioration, thereby reach the purpose of anti-biological pollution, and do not contain elements such as any tin, copper ocean environment existence harm from the slow release of microcapsule; Therefore, has advantage nontoxic, that timeliness is long; And because this coating can reach good anti-marine biofouling effect under lower concentration; Use the antifouling paint that contains a large amount of Red copper oxide to compare with tradition; Therefore use cost greatly reduces, and can overcome existing anti-soil technology weak effect, toxicity is big, cost is high shortcoming preferably;
2, the effect of the anti-marine biofouling of this antifouling paint is remarkable, can effectively prevent adhering to of marine lifes such as barnacle, algae, shellfish in 12 months;
3, this antifouling paint can be through the preparation and the convenient control of the addition in coating thereof of microcapsule in the rate of release of middle low-energy liquid;
4, the preparation technology of this antifouling paint is simple, and easy handling uses conventional equipment fully, is suitable for large-scale application.
