Description

Environment-friendly polyurea composition antifouling anticorrosive paint
Technical Field
The invention relates to the technical field of coatings, in particular to an environment-friendly polyurea composition antifouling and anticorrosive coating.
Background
The antifouling paint for ships or offshore structures is added with an antifouling component arsenic or mercury to prevent marine organisms from attaching. However, since arsenic or mercury causes marine pollution, cuprous oxide Cu is used2O as an alternative antifouling agent, cuprous oxide Cu2Dissolving O in seawater, and adding CuCl2In the form of a film having antifouling properties, if CuCl is present2Further oxidized and Cu forms are present, which causes a problem that the antifouling property cannot be obtained. In addition, tributyltin oxide is used as an alternative antifouling agent, and although tributyltin oxide has excellent antifouling performance, it is toxic to all living organisms in the ocean and causes serious marine pollution if only a small amount of Tin is present, so that tributyltin oxide is a limiting compound, and research and development of (Tin-free) antifouling paint without Tin component is continuously conducted.
International publication No. WO2003/037932 discloses an antifouling paint composition comprising a metal-containing copolymer, 4, 5-dichloro-2-N-octyl-4-isothiazoline-3-silver and a metal pyrithione compound.
Korean laid-open publication No. 2007-0071552 discloses a copolymer binder for an antifouling paint, which is intended to provide a Self-polishing non-Tin (seif Polishingcopolymer Tin-free) antifouling paint composition for preventing marine organisms from adhering by minimizing the surface energy of a coating film, and comprises a metal ester monomer, a silicon-based methyl acrylate monomer, an acrylic or vinyl unsaturated monomer, and a vinyl polysiloxane, and an antifouling paint composition comprising the same.
International publication No. WO2007/074658 discloses a high-solid antifouling coating composition comprising a carboxyl group-containing copolymer having a structural unit derived from an unsaturated compound monomer which is copolymerizable with a carboxylic acid monomer and an antifouling agent, a polyvalent metal compound being reactive with the carboxyl group-containing copolymer, a polyvalent metal compound and an antifouling agent, and a method for forming a coating film on the surface of a high-solid antifouling coating composition, an antifouling coating film, a substrate to which the coating film is attached, an antifouling substrate, and a high-solid multi-liquid antifouling coating composition. The above-mentioned prior art is a technology for replacing an organotin-containing antifouling paint, and is characterized by not containing a seawater fouling component, but has problems that the desired antifouling performance cannot be obtained, the loss rate of a coating film is increased by seawater, and the running performance of a ship is adversely affected. Further, there is a problem that the inclusion of seawater pollution components cannot be completely eliminated.
The alternative paint to the organotin-containing antifouling paint must have at least the same antifouling performance as the known antifouling paint containing tributyltin oxide or cuprous oxide and favorably affect the general performance of ships. Meanwhile, the alternative coating has good ecological environmental protection property. In the case where the surface free energy is low and the contact angle is large, marine organisms may not adhere to the surface of the ship or the adhesion may be impaired, and in the case where moisture hardly adheres, the already adhered marine organisms may easily fall. On the other hand, if the surface illuminance of the coating film is small or the friction coefficient is small, the fuel consumption of the ship can be reduced. Therefore, it is necessary to develop alternative paints to organotin-containing antifouling paints based on this viewpoint.
Disclosure of Invention
In order to solve the problems, the invention provides an environment-friendly polyurea composition antifouling and anticorrosive paint which can prevent marine organisms from attaching to ships or marine structures, reduce fuel consumption, prevent harmful substances from being discharged to the sea and is environment-friendly.
In order to solve the technical problems, the invention adopts the following technical scheme:
an environment-friendly polyurea composition antifouling and anticorrosive paint comprises a prepolymer solution and a resin solution, wherein the prepolymer solution and the resin solution are mixed in a ratio of 1: 1 and then used; the prepolymer solution is prepared by 100 weight percent of methylene diisocyanate, and the methylene diisocyanate contains 7 to 13 percent of NCO; the resin solution comprises 43 to 49 weight percent of polyoxypropylene diamine, 7 to 10 weight percent of polyether triamine with the molecular weight of 5000, 14 to 19 weight percent of polydiphenylamine, 7 to 19 weight percent of silane compound, 1 to 8 weight percent of modified fluororesin, 5 to 8 weight percent of modified resin filler, 1 to 3 weight percent of binder and 1 to 3 weight percent of pigment,
[ chemical formula 1]
Figure BDA0002327401880000031
Wherein the preparation method of the silane compound comprises the following steps:
s1, forming Si-O repeating units
The formation of the Si — O repeat units can be achieved in a variety of ways. For example, the Si-O repeating unit may be formed of an organic silicon such as a hydroxyl-modified silicon, an amino-modified silicon, an epoxy-modified silicon, a vinyl-modified silicon or a carboxyl-modified silicon; the Si — O repeating units may be prepared from a silicate such as lithium silicate, calcium silicate, sodium silicate or potassium silicate. Si-O repeating units can be formed by inducing a sol-gel reaction by adding a metal hydroxide such as KOH or Al2 (OH)3 to the colloidal silica. The Si-O repeating unit may be formed by various methods, and the present invention is not limited to a particular method. However, depending on the method of forming the repeating unit, the reaction in the next step for introducing the functional group may be different. For example, in the case where the Si — O repeating unit is prepared from organically modified silicon and has an amine group, polyisocyanate may be added for the formation of a urea bond. Also, if the Si — O repeating unit is prepared from a metal silicate, it is not necessary to separately perform a metal addition reaction;
if Si-O repeating units are formed, the bonds formed from the Si-O repeating units can be identified. The bond formed from the Si — O repeating unit may be a bond such as a urea bond or a urethane bond, but the present invention is not limited thereto. For example, a urea linkage may be formed by adding a polyisocyanate and a polyamine, and a urethane linkage may be formed by adding an alcohol and an isocyanate. In addition, various bonds can be derived according to the physical properties required for the coating film. For example, various forms of bonds may be derived to improve the function of preventing marine organism adhesion. Also, epoxy or acrylic bonds may be derived for improved adhesion to marine or marine structures.
S2, determining key structure
If the bond structure to be formed is determined, the functional group attached to the repeating unit can be determined. The functional group to be attached to the repeating unit may have various forms, but it is particularly necessary to attach a functional group which can express hydrophobicity and a functional group which can moderate hardness. The functional group for exhibiting hydrophobicity includes octyl, butyl, and phenyl groups, and the functional group capable of alleviating hardness includes a vinyl group and an ether group. In particular, the ether group can reduce the bending strength of the silicone resin, increase the flexibility of the resin, and thus can increase the self-movement of the surface of the formed coating film. The Si — O repeating unit forms a silicone structure as a whole, and the silicone structure has a low friction coefficient, but has a disadvantage of being difficult to apply to a curved surface due to high bending strength due to high hardness, and the vinyl group and the ether group can supplement the disadvantage of the silicone structure;
although a compound having a hydrophobic group and a group for moderating hardness may be added alone, a compound having such a property may be preferably added. Examples of the compound having both hydrophobicity and hardness relaxation property include a silane compound, and specifically, tetramethoxysilane, tetraethoxysilane, methyltrimethoxysilane, vinyltrimethoxysilane, acryloxypropyltrimethoxysilane, diphenyldimethoxysilane, butyltrimethoxysilane, n-octyltriethoxysilane, butyltriethoxysilane, octyltriethoxysilane, isobutyltrimethoxysilane, phenyltrimethoxysilane, diphenyldimethoxysilane, isobutyltriethoxysilane, octyltrimethoxysilane, dipropyltrimethoxysilane, butyltriethoxysilane, ethertrimethoxysilane, ethertriethoxysilane, diethanedimethoxysilane, or diethanediethoxysilane. In order to prepare the antifouling paint composition of the present invention, for example, tetramethoxysilane having hydrophobicity and vinyltrimethoxysilane having hardness moderation may be added in predetermined amounts to attach functional groups of Si — O repeating units. Alternatively, various forms of alkoxysilanes or organosilanes may be attached as functional groups to the Si — O repeat units. Such a silane compound can be attached to the Si — O repeating unit by an addition reaction or a silane coupling reaction.
S3, determination of functional groups
From step S2, a functional group can be determined, and if the functional group is determined, whether to add or what metal compound to add can be determined.
S4, adding a metal compound
The metal compound may be added for the purpose of improving antifouling property, or may be added for the purpose of preventing corrosion of the surface of the marine structure or the ship. For example. A metal compound such as cuprous oxide, zinc sulfide, zinc pyrophosphate, or copper tripolyphosphate may be added to improve the antifouling property, and a metal such as zinc, aluminum, potassium, lithium, calcium, sodium, or copper may be added to prevent corrosion. The metal may be attached directly to the Si — O repeating structure or as a functional group of the Si — O repeating unit in a form of being bonded to an organic compound. For example, aluminum can be bonded to the Si — O repeating units in a form substituted with Si phase by substitution reaction, and zinc or sodium can be bonded to the Si — O repeating units in a form bonded to an organic substance such as ethanol. The marine organic antifouling agent can be used alone for improving antifouling performance. For example, organic antifouling agents such as amine-organoboron or pyridine-triphenylboron can be attached to the Si-O repeating units or added separately.
S5, adding a curing agent
The curing agent may be, for example, a resin such as an epoxy resin, an acrylic resin or a polyester resin, a curing catalyst and a dispersant.
Preferably, the modified resin filler is a nano silicate.
Preferably, the binder is one of β - (3, 4-epoxycyclohexyl) ethyltrimethoxysilane, gamma-propyltrimethoxysilane and gamma-methacryloxypropyltrimethoxysilane.
Compared with the prior art, the invention has the following beneficial effects:
1. the marine organism-free energy-saving building block has low free energy and low friction coefficient, can prevent marine organisms from attaching to ships or marine structures, reduces fuel consumption, does not discharge harmful substances to the sea, and is green and environment-friendly.
2. The invention has excellent wear resistance and mechanical physical property, can prolong the recoating time caused by the abrasion of a coating film, and can save the cost for maintenance.
