[Background]

In general, submerged portions of ships and offshore structures are provided with antifouling coatings to prevent corrosion of the ship and a drop in cruising rate due to the attachment of marine organisms such as clamshells, shellfish and seaweeds. The antifouling coating is also applied to structures used in farming fisheries to prevent fatal conditions of fish due to the attachment of marine organisms to the structures.

Antifouling materials are usually contained in antifouling coatings.

Marine life such as oysters, mussels, seaweeds, etc. are easily attached to ships, fishing nets, and other underwater structures, thereby preventing efficient operation in ships, causing fuel waste, and clogging in fishing nets. Problems or shortened service life. In order to prevent the adhesion of living organisms to these underwater structures, the antifouling paint is usually applied to the surface thereof.

Representative antifouling paints conventionally used include matrix antifouling paints in which rosin is blended with vinyl resins, alkyd resins, and the like, which are insoluble in seawater.

However, since the antifouling agent elutes together with rosin in seawater, it is impossible to expect stable antifouling properties for a long time, and since the insoluble resin portion remaining in the coating forms a skeletal structure, especially when applied to ships, the resistance between seawater and the coated surface This increases and has the drawback which causes speed fall etc.

In addition, tributyltin TBT is a kind of organic tin compound (BTs), which is a major component of paint mainly applied to the bottom of ships or marine structures to prevent corrosion of the ship and prevent fish and shells from sticking.

In addition, the organic tin compounds (BTs) include MBT and DBT, which are used as plastic additives in addition to TBT, which have a fatal effect on marine organisms such as fish and shellfish.

TBT, the most toxic of BTs, kills fish and shellfish even at low concentrations, and induces infertility by causing male genitalia in females of gastropods, such as shellfish and conch.

For this reason, use is regulated in the United States, and the UK has set 2 ng / l and Japan 10 ng / l.

In order to solve the above problems, various companies are researching non-toxic antifouling paints.

For example, JP-A-62-57464 and JP-A-62-84168 describe hydrolytic antifouling paints using a copolymer having a metal containing group at the end of the side chain. JP-A-11-35877 and JP-A-2002-012630 describe copolymers comprising metal-containing polymerizable monomers as vehicles and self-polishing paint compositions containing antifouling agents.

JP-A-62-252480, JP-A-63-2995, JP-A-5-78617 and JP-A-5-287203 have reactive curable (crosslinkable) silicone rubbers containing silicone oils, hydroxyl groups An antifouling paint composition using a silicone resin having or a polysiloxane having a silanol group is described.

JP-A-62-156172 describes antifouling paint compositions containing a polymer having polydimethylsiloxane groups as side chains to form a coating having low surface tension properties of the polymer.

In addition, JP-A-2001-72869 describes a copolymer having a polysiloxane structure and a paint composition having a metal salt of a special organic acid group as a side chain to form a coating having an antifouling effect even when no antifouling agent is contained.

However, the metal-containing copolymers described in the above-mentioned JP-A-62-57464, JP-A-62-84168, JP-A-11-35877 and JP-A-2002-012630 to obtain sufficient antifouling effect. The antifouling paint using N is required to contain a large amount of antifouling material.

Antifouling paints using low surface tensions described in JP-A-62-252480, JP-A-63-2995, JP-A-5-78617, JP-A-5-287203 and JP-A-62-156172 It is difficult to maintain low surface tension in seawater and show antifouling effect for a long time, and these paints have a problem of low adhesion to the substrate.

The copolymer used in JP-A-2001-72869 is obtained by reacting a monovalent organic acid residue and a divalent metal oxide on the side chain of a copolymer having a polysiloxane structure and a carboxyl group, but it is not easy to add metal atoms to the carboxyl group. As a result, paints using airborne copolymers tend to be difficult to show self polishing stability and antifouling effects for long periods of time. The paint has a problem of low adhesion to the substrate, and also has a problem that the antifouling effect is lowered when the pigment is added to the coating composition containing the copolymer.

The present invention relates to a catalyst antifouling paint composition having a water purification function to improve the above problems. In the mixture for the preparation of the anti-catalyst antifouling paint, the mixture contains 10 to 20% by weight of tourmaline tourmaline and monazite; 3 to 10% by weight of titanium dioxide; Carbon black graphite 3 to 10% by weight; 0.1 to 1 weight percent silver (Ag +); 30 to 60% by weight of acrylic resins and urethanes; 0.5 to 3% by weight of slip agent; It provides a catalyst antifouling paint composition containing 5 to 35% by weight of a hydrocarbon solvent and a ketone solvent.

The anti-catalyst antifouling paint composition prepared according to the present invention is non-toxic and effectively radiates negative ions and negative ions after coating, and generates electric oxidation energy, thereby purifying water, shielding electromagnetic waves, protecting outer walls of underwater structures, and inhibiting adhesion of underwater microorganisms. It has an environmentally friendly function to reduce energy loss.

The present invention relates to a catalyst antifouling paint composition having a water purification function. In the mixture for the preparation of the anti-catalyst antifouling paint, the mixture contains 10 to 20% by weight of tourmaline tourmaline and monazite; 3 to 10% by weight of titanium dioxide; Carbon black graphite 3 to 10% by weight; 0.1 to 1 weight percent silver (Ag +); 30 to 60% by weight of acrylic resins and urethanes; 0.5 to 3% by weight of slip agent; A catalyst antifouling paint composition comprising 5 to 35% by weight of a hydrocarbon solvent and a ketone solvent, wherein the catalyst antifouling paint composition prepared according to the present invention is non-toxic and effectively radiates far-infrared rays and anions after coating, and generates oxidative electric energy.

The composition, function, and action of the composition in a mixture for preparing a cocatalyst antifouling paint composition will be described in detail.

1. Far Infrared Ray, Anion, Oxidized Electric Energy Radiating Material

1.1.1 Tourmaline, monazite crushed particles and content

In the present invention, the functional cocatalyst antifouling paint composition having a water purification function is a material capable of emitting far infrared rays, and tourmaline and monazite powders are 0.01 to 40 μm, preferably 0.01 to 10 μm. The functional cocatalyst paint tourmaline and monazite content, which is pulverized and used for water and air purification, is 15 to 20% by weight based on the total weight.

According to a preferred embodiment of the present invention, the tourmaline and monazite powders as these far-infrared radiating materials are ground to 0.01 to 40 μm, preferably having an average particle size of about 0.1 to 5 μm, and used for water and air. Functional tourmaline paint tourmaline and monazite content with purifying function is used based on the total weight of 15% by weight.

1.1.2 Tourmaline and monazite functions

Tourmaline monazite of the present invention is a chemical component of (Ce, La, Y, Th) PO4 spontaneous spectroscopy and when there is water in the vicinity of the electrolysis of water (water molecules) hydroxyl ionization To generate negative ions.

Tourmaline and monazite are borosilicates with hexagonal columnar crystals and are natural minerals in the hexagonal system. Tourmaline monazite crystals have the nickname of tourmaline because they have the property of generating electricity. Tourmaline crystals absorb the electrons in the atmosphere (absorption) and divergence (repulsion) repeatedly, and no matter how small the powdering process, each particle continuously generates a weak current of 0.06mA. ) Is instantaneously electrolyzed against water. At this time, water is electrolyzed and molecules (H 2 O) are separated into hydrogen ions (H +) and hydroxyl ions (OH −).

The separated hydrogen ions (H +) are attracted to the negative electrode of the tourmaline particles and are combined with the electrons emitted therefrom to neutralize them, becoming hydrogen gas (H2) and diffusing and evaporating in the atmosphere. That is, water becomes alkali ionization. In addition, hydroxyl ions (OH-) combine with the surrounding water molecules to form a surface active substance called a hydroxyl (H3O2-) anion.

This is commonly defined as anion. That is, H 2 O is separated into H + and OH −, and the separated H + and OH − generate hydronium ions and hydroxyl ions.

H + + H2O-> H3O + (HYDRONIUM ION) OH- + H2O-> H3O2- (HYDROXYL ION)

The hydrogen element is dropped by tourmaline and monazite, and the railing Hydroxyl ions, or sole ions, are opposite to this law, making them unstable in terms of energy. For this reason, Hydroxyl ions exist in an unstable state in water, so they rapidly move to the interface and arrange H-O-H groups toward the inside of the water and H of the O-H groups toward the outside of the water.

As such, the hydroxyl ions are stabilized to act as surfactants. In addition, the tourmaline monazite air purification effect is a physical property of the tourmaline, and no matter how small the grinding process, the tourmaline physical properties and molecular structure does not change, especially heat, friction, pressure and impact Rather, the effect of water purification and air purification will be very high in that the production of anionic surfactants is maximized.

1.2.1 Titanium Dioxide Grinding Particles and Content

On the other hand, the present invention is a functional cocatalyst antifouling paint composition having a water purification function of 5 nm to 20 nm as a titanium dioxide [Anatase] material capable of emitting far infrared rays, preferably in the range of 10 to 15 nm. It is pulverized and used to receive light energy and catalyze the action to generate 3.2 eV of electric oxide energy.

1.2.2 Titanium Dioxide Function

Titanium Dioxide Photocatalysts do not change in certain chemical reactions, they serve to change the reaction rate or initiate the reaction.

Photocatalyst refers to the catalysis of light energy. Photocatalysts include zinc oxide (ZnO) and cadmium selphide (CdS), but titanium dioxide that does not photodecompose itself is the most active.

When light hits titanium dioxide, it produces electrons with negative electricity and holes (micropores) with positive electricity. These electrons and holes have strong reducing and oxidizing power. Applying this reducing and oxidizing power to decompose water yields hydrogen and oxygen. Accumulate this to get heat and electricity when needed.

Photocatalyst refers to special catalysts (Catalyst of Photo-reactions) that accelerate the photoreaction by irradiating light on the surface of the catalyst. As with the general catalyst requirements, the photocatalyst participates directly in the reaction, but should not be consumed by itself, and accelerates the reaction rate through a reaction mechanism path different from the conventional photoreaction.

Photocatalytic reactions that convert light energy into chemical energy using photoreactive powders represented by TiO2 have been studied and studied for their use in the generation of hydrogen (H 2) through water decomposition and organic synthesis reactions. In addition, as environmental issues are rapidly emerging, "photocatalysts as environmentally friendly catalysts" that can use solar light, which is a clean and infinite energy source, have attracted attention. The use of photocatalysts for environmental purification has led to the reduction of CO2, the direct decomposition of NOx and SOx, the removal of odors caused by volatile organic compounds, and the purification of polluted rivers and lakes. Decomposition of NOx and volatile organic compounds is of great interest in terms of practicality.

In general, heterogeneous photocatalytic reactions proceed on the semiconductor surface. In the semiconductor absorbing light energy, electron transition from valence band to conduction band occurs, and the generated holes or electrons in the conduction band move to the adsorption material or surface functional group. To participate in the reaction. In this case, an electric field is formed due to the movement of electrons, thereby forming a space charge region in which a bending of an electron band occurs in the surface portion of the semiconductor.

Holes (h +) or electrons (e-) formed through this process will disappear through one of the following three reactions.

(1) photocatalytic reaction

Aads (adsorbent A) + h + → (Aads) + Bads (adsorbent B) + e- → (Bads)-(Aads) + + (Bads) → product

(2) change of grid

h + + lattice → (lattice) + (lattice) + → lattice reaction product

(3) recombination of holes and electrons

h + + e- → thermal energy

In the above reaction (1), the formation, the hole, and the electron are finally recombined, but the light energy already absorbed is used to supply the activation energy of the reaction. The semiconductor used in the reaction remains unchanged.

In the case of (2) the reaction, the semiconductor used in the reaction causes the semiconductor itself to change as the reaction proceeds. In fact, sulfide-based semiconductors such as CdS easily cause photocorrosion in aqueous solution by irradiation of light.

The reaction of (3) is a case where the generated holes and electrons do not participate in the photocatalytic reaction and recombine directly. Therefore, the bending of the electron band in the space charge layer causes the generated holes and electrons to move in opposite directions, thereby ultimately preventing recombination. As a result, the possibility of participating in the generated holes, electrons, or catalytic reactions increases, which is an important factor in the heterogeneous photocatalytic reaction.

1.3.1 Carbon Black and Graphite Grinding Particles and Content

The present invention is a functional cocatalyst antifouling paint composition having a water purification function, and carbon black and graphite pulverized particle powder are pulverized to a size in the range of 10 to 30 μm, preferably 15 to 20 μm, and used for water and air purification. The functional cocatalyst carbon black and graphite pulverized particle content having a function are used in the range of 3 to 10 wt% based on the total weight of 4 wt% carbon black and 4 wt% graphite.

According to a preferred embodiment of the present invention, carbon black and graphite pulverized particle powders are preferably used in the range of 10 to 30 μm as the far-infrared radiating material, and have a water purification function. The carbon black and the graphite powder content in the composition are based on the total weight of 8% by weight to 4% by weight of carbon black and 4% by weight of graphite.

1.3.2 carbon black and graphite functions

According to the present invention, the functional black catalyst antifouling paint composition having a water purification function is produced by incomplete combustion of natural gas by heating wood at a high temperature while blocking air, and carbon atoms are arranged in a disordered hexagonal shape in carbon and carbon black. It is.

They have excellent adsorptive power and are used as decolorizing deodorant. Called fullerenes in particular, they are shaped like balls. In the C60, for example, 60 carbons are rounded together like a soccer ball. Sixty carbon atoms combine in a hexagonal shape like most graphite, and some have a five-sided shape.

In addition, they not only conduct electricity when redox, but also show superconductivity at low temperatures.

Natural graphite is composed of carbon, and most of the crystals are hexagonal and some are trigonal. Carbon is connected in a hexagon like a benzene ring, and these hexagons form a plate and form a continuous layer.

Carbon atoms have three strong covalent bonds in the plane of electrons, and one remaining electron is bonded to the upper and lower layers.

The height of one layer on the hexagonal plate is 3.40Å and the distance between the nearest carbons in the hexagonal ring is 1.42Å. The distance between the upper and lower layers of the platelets is much larger than the center distance of the two carbon atoms (the radius of the carbon atoms is 0.77Å and the carbon ions are 0.16Å).

For this reason, since the electrons upward on the hexagonal plate can move somewhat freely, graphite has good electrical conductivity.

Due to the good conductivity of graphite, the carbon atoms between the upper and lower platelets have an interaction and overlap with the valence electron band and the conduction band, and become 0.03 eV, and the same number of free electrons and holes are semimetallic. . The resistivity is about 100 times larger in the c-axis direction than in the other directions. There is no forbidden band, and the valence electron band and the conduction band are superimposed by the magnetic field, so they have a very large diamagnetic property, so the covalent bond is good and the oxidative energy is activated. It can block electromagnetic waves in the MHz to GHz region.

Stable to water and oxygen, black ozone turns to AgO in ozone and black sulphide to AgS in sulfur and hydrogen sulfide. It does not react with hydrogen, nitrogen, and carbon dioxide even at high temperatures, but with halogens.
