In general, an antifouling paint composition is intended to prevent adhesion and growth of marine organisms causing pollution to bottom shell plates and marine structures that are immersed in seawater. When these marine organisms are attached to the bottom shell, the frictional resistance between the surface of the coating and the seawater increases during operation of the ship, which can greatly increase the fuel cost, which accounts for a large part of the operating expense.
Conventionally, antifouling coating compositions using marine polystyrene (CDP) and self-polishing copolymer (SPC) prepared by mixing copper oxide with various synthetic resins and rosin as binders have been used Has come.
However, the organotin compounds eluted by the seawater during the hydrolysis of the binder contained in the marine antifouling paint composition were identified as harmful substances.

<Self Lubricity Branch Antifouling paint Description of composition>
A general marine antifouling paint composition is applied to prevent marine life from adhering to the bottom shell. The antifouling coating composition having self-lubricating property of the present invention is used for marine use. In order to improve or maintain the antifouling performance and abrasion resistance, a lubricant in a solid state which lowers the surface tension between the surface of the coating film and seawater is added to the antifouling paint composition, There is a characteristic that it has lubricity.
Here, the coating film means that a thin layer of the antifouling painted on the bottom shell is dried, solidified, and deposited to form a continuous film. That is, the coating film is one in which the solvent, which is one of the compositions of the antifouling paint, is evaporated, and the remaining components are each formed with a coating by inherent characteristics.
Further, the lubricant of the present invention lowers the frictional resistance between the surface of the coating film and seawater, thereby restraining or minimizing the adherence and growth of various marine organisms on the bottom plate, thereby improving the antifouling performance and abrasion resistance, It plays a role.
The antifouling paint composition having self-lubricating property of the present invention will be described in detail. The antifouling paint composition having self-lubricating property includes a binder, a lubricant, an antifouling agent and a solvent, and may further contain additives.
The binder helps to lower the surface tension of the coating when the binder dissolves in seawater as the hydrolysis progresses. It also improves the crack resistance, weatherability, and heat resistance of the formed coating film, thereby stably maintaining the antifouling performance in the seawater. .
Here, the binder preferably includes 10 to 30 parts by weight. This is because when the binder is contained in an amount of less than 10 parts by weight, durability and abrasion resistance of a coating film for realizing a proper antifouling performance are lowered.
In addition, when the binder is contained in an amount exceeding 30 parts by weight, the rate of abrasion is too high to cause excessive hydrolysis of the coating film, resulting in a decay of the coating film or deterioration of physical properties, and the amount of the antifouling agent to be compounded is insufficient depending on the amount of the binder It is difficult to maintain long-term antifouling performance.
The binder may be any one of acrylic resin and vinyl resin, or a combination thereof.
Here, the binder may be provided with a resin having a self-abrading or magnetic pattern and may be provided with an acrylic resin having a linear structure, when the binder is finely abraded by the hydrolysis reaction upon contact with seawater.
Specifically, the acrylic resin may be formed of any one or a combination of copper acrylate resin, zinc acrylate resin and silyl acrylate resin, It does not.
As described above, the lubricant is an important antifouling coating composition which lowers the frictional resistance between the surface of the coating film and seawater, and preferably contains 1 to 20 parts by weight. If the lubricant is contained in an amount of less than 1 part by weight, the lubricating effect of the coating film surface can not be exhibited. If the lubricant is contained in an amount exceeding 20 parts by weight, the surface energy of the coating film is sufficiently lowered, It is because it occurs.
Here, the lubricant may be provided by any one of molybdenum disulfide, boron nitride, graphite, Graphene, carbon nanotube, and tungsten oxide, but is not limited thereto .
Further, the lubricant is preferably provided as a solid lubricant. This is because the solid state lubricant is always present on the surface of the coating to a certain level, and the frictional resistance between the seawater and the surface of the coating can be reduced, which is very effective in preventing adhesion and growth of various marine life on the bottom shell .
The antifouling agent includes both organic and inorganic compound forms, and preferably contains 0.1 to 70 parts by weight of the antifouling agent. If the antifouling agent is contained in an amount less than 0.1 part by weight, it is difficult to obtain an effective antifouling performance. If the antifouling agent is contained in an amount exceeding 70 parts by weight, the water resistance and abrasion resistance of the coating film are lowered.
The antifouling agent preferably includes at least one of an organic antifouling agent and an inorganic antifouling agent, which comprises 0.1 to 20 parts by weight of an organic antifouling agent and 5 to 50 parts by weight of an antifouling agent.
The organic antifouling agent may be any one selected from the group consisting of a thiazolone group, a thiocarbamate group, a pyrithione group, a polyurea group, and a pyridine group .
On the other hand, the antifouling agent may be prepared by a copper compound including copper thiocyanide or copper halide, but is not limited thereto.
The solvent may be prepared from various solvents used in the antifouling paint composition, and more specifically, it is preferably one selected from among aliphatic hydrocarbons, aromatic hydrocarbons, ketones, esters and ethers Do.
In addition, the solvent preferably contains 1 to 50 parts by weight, depending on the physical properties of the antifouling paint. This is because when the solvent is contained in an amount less than 1 part by weight, the workability to be coated on the bottom shell is deteriorated, and the performance on site is deteriorated. When the solvent is contained in an amount exceeding 50 parts by weight, the physical properties of the coating film, .
The antifouling paint composition having self-lubricating properties of the present invention may further contain additives as required, and may be provided with at least one of zinc oxide, a thickener, a plasticizer, a defoaming agent and a pigment, The following is an explanation.
First, zinc oxide is a compound of oxygen and zinc. It is a light white powder and is also called zincification and zinc bag. It exists in nature as a red iron oxide and can be obtained through combustion, heating, and the like. Such zinc oxide not only improves the strength of the coating film but also controls the speed (performance) of wear and also plays a role of coloring.
Also, the thickener may be provided by any one of clay, bentonite and amide wax, or a combination thereof, and serves to prevent flow and settling of the antifouling paint.
The plasticizer can be provided with chlorinated paraffin and plays a role of improving the flexibility of the coating film, preventing aging, and improving durability.
In addition, the antifoaming agent acts to improve the performance by suppressing bubble generation in the coating film during the coating operation.
Additionally, the pigment may be provided by any one or combination of titanium white, red iron oxide, red pigment and talc.
Such an additive preferably comprises 1 to 20 parts by weight.
For example, when the plasticizer is used as an additive for the antifouling paint composition of the present invention, the plasticizer preferably comprises 1 to 20 parts by weight. This is because when the plasticizer is contained in an amount exceeding 20 parts by weight, a part of the surface of the coating film is exposed in a state not mixed with the coating film, thereby deteriorating physical properties of the coating film.
As described above, the antifouling paint composition having self-lubricating properties of the present invention may further contain various kinds of additives as needed in order to improve the physical properties of the coating film and obtain a desired effect. Such additives are not limited to the kinds of the above-mentioned additives But it is not limited to the above-described components depending on the kind of the additive.

( Antifouling performance exam)
A sealant coating (sealant coat) 100 (占 퐉) was coated on a PVC sheet having a size of 300 占 퐉 (dry film thickness) and 300 占 100 占 2 (mm) in the antifouling paint compositions of the examples and comparative examples shown in Table 1 The test specimens were prepared by curing and drying at room temperature for one week.
Thus prepared test specimens were immersed 1 m below sea level using a raft-shaped test apparatus (Pontoon) installed on the East Coast of Busan, Korea. The fouling performance was evaluated according to the evaluation criteria shown in Table 2 below by observing the degree of contamination of the coating film due to the attachment of marine organisms for a total of 18 months periodically every two months after immersion and the results are shown in Table 3 below .
As can be seen from the results of the antifouling performance test shown in Table 3, the antifouling paint compositions of Examples 1 to 6 were excellent in antifouling performance up to 10 months before, and even after prolonged time of 10 months or longer, To C-grade, it can be confirmed that the long-term antifouling property is excellent. This is because the antifouling paint composition of the present invention has a self-lubricating property through a solid-state lubricant, thereby delaying attachment of marine life to the bottom shell.
Specifically, the difference in antifouling performance between the antifouling paint compositions of Examples 1 to 6 and the antifouling paint compositions of Comparative Examples 1 to 3 will be described below.
First, the antifouling paint compositions of Examples 1 to 6 are provided with a lubricant such as molybdenum disulfide, boron nitride, and graphene in a solid state and do not move in the coating film, so that wear is generated on the surface of the coating film.
On the other hand, the antifouling paint compositions of Comparative Examples 1 to 3 were prepared as a lubricant such as liquid grease, mineral vegetable oil, and emulsified oil, and were released to the outside by diffusion in the coating film.
Therefore, the lubricant contained in the antifouling paint compositions of Examples 1 to 6 is always present on the surface of the coating film at a constant level, so that the frictional resistance between the surface of the coating film and the sea water can be reduced and the antifouling performance is excellent.
On the other hand, the lubricant contained in the antifouling paint compositions of Comparative Examples 1 to 3 was abruptly lowered with time, and the self lubricating function on the surface of the coating film was lost, so that the degree of contamination of the bottom shell was increased.
In addition, the antifouling paint composition of Example 2 showed better long-term antifouling performance than the antifouling paint composition of Example 1, and when the same lubricant was included, the antifouling paint composition of Example 2 contained the antifouling paint of Example 1 This is because the content (parts by weight) of the lubricant is higher than that of the composition.
For this reason, the antifouling paint compositions of Examples 4 and 6 are also superior in antifouling performance to the antifouling paint compositions of Examples 3 and 5, respectively.
In addition, it can be confirmed that the antifouling paint compositions of Examples 2 and 6 have the best antifouling performance as a whole. Accordingly, the antifouling paint composition having self-lubricating properties according to the embodiment of the present invention preferably contains 15 parts by weight of molybdenum disulfide or 15 parts by weight of graphene as a lubricant.
(Wear performance (speed) test)
The antifouling paint compositions of the examples and comparative examples shown in Table 1 were continuously coated at a constant interval on a circular PVC plate having a diameter of 600 (mm) on the basis of a dry film thickness of 300 탆, cured and dried at room temperature for one week, .
The test piece thus prepared was connected to a motor at the center of a rectangular tank having a size of 2000 mm in height and 1500 mm in height and mounted on a motor. The speed of the motor 600 (rpm) ) Was rotated at a speed of 600 (Rpm), which is equal to the speed of 25 (knots) of a ship. The wear rate (performance) was evaluated by using a laser displacement meter, The results are shown in Table 4 below.
As can be seen from the results of the wear rate (performance) test of Table 4, the antifouling paint compositions of Examples 1 to 6 contain a lubricant such as molybdenum disulfide, boron nitride and graphene prepared in a solid state, For example, a lubricant such as a lubricant, a lubricant, a mineral oil, a mineral oil, a mineral oil, a mineral oil, Since the antifouling performance can be maintained, the average wear rate is low.
Therefore, the antifouling paint compositions of Examples 1 to 6 can maintain the same thickness of the coating film for a long time because the average wear rate is low, and thus the long-term antifouling performance and storage stability are excellent.
As described above, according to the present invention, a lubricant in a solid state is contained in the antifouling paint composition to have self-lubricating property, so that frictional resistance between the surface of the coating film and seawater can be remarkably reduced.
In addition, since it has a low frictional resistance between seawater and the coating, it minimizes adherence and growth of various marine life on the bottom shell, thus saving fuel cost for ship operation.
Since the antifouling paint composition contains a solid lubricant and the average wear rate is low, it is possible to maintain the thickness of the same coating film for a long time, so that the antifouling performance can be maintained for a long time, and the long-term antifouling performance and storage stability are excellent.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. And the scope of the present invention should be understood as the scope of the following claims and their equivalents.
