-1- 24947 / Vk / mvl

Short designation: Final composition for painting ships.

The invention relates to sealing compositions for painting ships. Paint compositions based on an oil or alkyd resin are used as a support for paint with an anti-corrosive effect. Recently, paints having a drying character have been developed by evaporating solvent containing chlorinated rubber or denatured vinyl resin as a support and have been widely used to replace the paint containing oil or alkyd resin as a support. Paints with a dirt-repellent effect are applied to a paint with an anti-corrosive effect and they generally contain a polymer of the same system as used in the paint with an anti-corrosive effect.

On the other hand, cross-linked polymer paints such as an epoxy resin and a tar-based epoxy resin from coal or a paint containing a denatured coal tar-based vinyl resin as a support have become important because these paints have been used for a long time. have an anti-corrosive effect for a longer period of time. Furthermore, turpentine resin has been added to a paint with a dirt-repellent effect based on an oil or alkyd resin, chlorinated rubber or denatured vinyl resin as a carrier in order to dissolve the dirt-repellants present in the paint and use has been made of dissolving the soil release agent from the paint layer associated with the hydrolysis and water solubility of turpentine resin.

However, such a paint has disadvantages because insoluble layers (generally referred to as a skeletal layer) are gradually formed on the surface of a ship's bottom as it sails, causing the surface of the hull bottom to become rough and the dirt-repellent or anti-fouling effect is significantly reduced.

In order to overcome such a drawback, various studies have been carried out, the result of which has been a significant improvement with respect to the dirt-repellent paint as currently used. Mostly used are copolymers of vinyl group-containing monomers which are generally referred to as acrylic resins.

This means that they essentially consist of at least one kind of copolymers of acrylic acid or methacrylic acid or various kinds of alkyl ester, hydroxy alkyl ester and amide thereof, styrene, vinyl toluene, itaconic acid, maleic

Although denatured vinyl resin and other resins compatible with these copolymers are partially added depending on the conditions, a paint containing such acrylic materials has been obtained primarily as a support, as well as copper oxide, organic tin-containing compounds and sulfur-containing compounds as soil repellents. used singly or in combination, which paints have become known under the designation "Long Life A / F", as a dirt-repellent paint which can maintain this effect for a long period of time.

Furthermore, copolymers of at least one kind of various acrylic esters or methacrylic esters and esters of methacrylic acid or acrylic acid and organotin compounds or organolead compounds such as "organo-metal copolymers" have been found to have a soil-repellent effect in that the bound organometallic compounds are separated from the polymers by hydrolysis. of the paint-containing coating and are removed from the surface of the hull by the flow of the seawater after the dissociation of the organo-metal compounds, allowing living organism to be excluded from the hull or removed from the surface of the hull, so that single organometallic compounds have been used in practice or in combination with various kinds of known dirt repellents. These are generally referred to as self-abrasive A / F type.

As a result of the continued investigation of the intended behavior under such conditions, an anti-corrosive paint and soil-resistant paint generally has a rather different polymer or resin as a carrier and therefore usually different types of paint are applied in layers.

This means that first an anti-corrosive paint containing coal tar, denatured vinyl resin, epoxy resin, epoxy resin coal tar or epoxy urethane resin coal tar is applied as a carrier and then the above-mentioned "Long Life A / F" or self-abrasive type. type A / F, which is applied directly to the anti-corrosive paint or first coating indicated as "primer" or sealing coating based on chlorinated rubber, denatured vinyl resin or denatured vinyl chloride coal tar as a support applied to an anti-corrosive paint which epoxy resin, epoxy resin coal tar or epoxy urethane resin coal tar contains as the carrier and then "Long Life A / F" or the self-abrasive type A / F.

Even when different types of paints based on f352352 * * -3- 24947 / Vk / mvl resin are applied in layers, as long as a dirt repellent paint is applied to the anti-corrosive paint, as mentioned above, no drying problems arise , bonding and the like of the applied film.

Nevertheless, there are problems with the systems currently used and these can be solved by the developments according to the invention. These problems are related to the fact that the hull comes into contact with an anchor or anchor chain, a buoy or the quay, objects floating at sea and the like, which damages the hull and in order to repair such damaged parts. applied an anti-corrosive paint as a coating. Such an anti-corrosive paint is applied to the dirt-repellent paint in the vicinity of such damaged areas. Furthermore, depending on the type of the dirt-repellent paint, it is preferable, depending on the circumstances, that a first coating is applied over the entire surface of the old dirt-repellent paint that remains on the surface of the bottom of the hull as binder and after that the dirt-repellent paint is applied to it.

In such a case, when the known anti-20 corrosive paint or coating is applied to "Long Life A / F" containing acrylic resin as the main component of the support or self-abrasive type A / F, when only the surface is dried while the layers of "Long Life A / F" or self-abrasive type A / F solvents below absorb, soften, significantly delay drying and solidification of the layers below and therefore drying and solidification will take two or three days Although drying and solidification of the respective single-use paint takes only a few hours, cracking occurs as a surface coating.

Furthermore, when an anti-corrosive paint such as tar epoxy paint and even tar epoxy paint whose cross-linking reaction has ended, the old A / F layer applied below and still containing solvents will remain under soft conditions, which is usually leads to the removal of layers of the paint film while sailing the ship.

These problems have been solved by using a sealing composition according to the invention and this sealing composition for painting ships is characterized in that it

24947 / Vk / ravl acrylic resin containing a glass transition point of 10 ° C or less in an amount of 10 to 70% by weight. With such a composition, the drawbacks associated with the known anti-corrosive paint and first coating can be eliminated, thereby successfully obtaining a "Long Life A / F" 5 containing acrylic resin as a carrier or self-abrasive type A / F .

While it is not yet clear why the sealing compositions of the invention present no problems when applied to an old "A / F" paint layer, it appears that when they contain similar acrylic resins as in the A '/ F paint layer and that acrylic resin has a glass transition temperature of 10 ° C or less, even when solvents are present in the compositions that temporarily penetrate the bottom layer of the old A / F paint layer, the solvents are partitioned between the old A / F paint layer and the composition according to the present invention in a well-balanced relationship, so that the difference between the old A / F paint layer present as the undercoat and the composition according to the invention when the solvent evaporates, i.e. the drying and therefore the drying and solidification of the paint film as a whole can be normalized. When the sealing composition of the invention is applied to an old A / F paint film and normally dried and solidified, no problems arise and insufficient adhesion even when A / F paint or tar epoxy paint is only applied on the barrier composition of the present invention.

It is important that acrylic resin is used in accordance with the present invention having a glass transition point of 10 ° C or less. When an acrylic resin is used with a glass transition temperature above 10 ° C, the effects of the present invention are reduced. Even a first coating containing only acrylic resin as a support not only gives insufficient performance but is also worse in terms of other properties depending on the conditions. The use of an acrylic resin with a glass transition point of 10 ° C or less in an amount of up to 70% by weight, based on the support, which is the main point of the present invention, as such gives an effect, with which the composition of a suitable combination can be obtained. Even when an acrylic resin is used with the lowest glass transition temperature, the favorable ft R (i 9 "<5 9 -5- 24947 / Vk / mvl effect cannot be obtained if it is not present in the support in an amount of at least 10 wt% Acrylic resin may be present in the support in a lower amount when the glass transition point is lower.

Acrylic monomers to provide the acrylic resin having a glass transition temperature of 10 ° G or less used in accordance with the present invention include the alkyl ester such as methyl ester, ethyl ester, propyl ester, butyl ester, hexyl ester, t-butyl ester, 2-ethylhexyl ester, octyl ester, lauryl ester and stearyl ester ; hydroxyalkyl ester such as hydroxy-10 ethyl ester and hydroxypropyl ester aminoalkyl ester such as dimethylaminoethyl and diethylaminoethyl, alkoxyalkyl ester such as methoxyethyl ester and ethoxyethyl ester of acrylic acid or methacrylic acid, acrylamide, methacrylamide, acrylonitrile, methacrylonitrile, cyclohexyl tyl ethyl ester, benzyl ester, benzyl ester, benzyl ester containing esters such as tributyl lead and triphenyl lead of acrylic acid or methacrylic acid and the like. In addition, the vinyl group-containing monomers copolymerizable with these acrylic monomers include styrene, vinyl styrene, vinyl toluene, maleic acid, fumaric acid, itaconic acid, vinyl acetate, vinyl chloride, and the like. Polymers with a glass transition temperature of 10 ° C or less obtained by polymerizing or copolymerizing at least one of these monomers at an appropriate ratio can provide the activity of the invention.

As mentioned above, the main factor of the composition according to the invention is the glass transition temperature. Polymers or copolymers with too high molecular weight have drawbacks in the application of paint. Polymers and copolymers with a molecular weight of 200,000 or less can be suitably used.

The polymers used in a solvent evaporation film-forming in a conventional manner to provide an anti-corrosive paint or first coat as a support can be used as a suitable resin or polymer in an amount of 90 to 30 wt. .%, added to the acrylic resin having the glass transition temperature of 10 ° C or less, which is used in an amount of 10 to 70% by weight as a carrier in the composition of the present invention. For example, chlorinated polyolefin such as chlorinated rubber, cyclized rubber, chlorinated polyethylene and chlorinated polypropylene, "denatured vinyl chloride resin" obtained from vinyl chloride 8502352 -6- 24947 / Vk / mvl and at least one type of vinyl chloride containing monomer such as vinyl chloride and vinyl acetate, vinyl chloride and vinyl isomethyl ether vinyl chloride and vinyl isobutyl ether and vinyl chloride, vinyl acetate and maleic acid; petroleum resins, coumarone resin, coal tar, coal tar containing pitch and other various types of plasticizer, optionally singly or in combination, are used.

In the preparation of the composition of the invention it is effective to use substances commonly used in the paint such as pigment fillers such as calcium carbonate, talc and barite, anti-rust pigments such as zinc phosphate, aluminum phosphate, zinc chromate and red lead aluminum powders, coloring pigments, stabilizers, pigment wetting agents, dispersants, leveling agents and flow improving agents, depending on the circumstances.

The invention will be further elucidated by means of the following examples, in which the parts relate to weight.

Example I

Return to a flask equipped with a reflux condenser, stirrer and thermometer with 250 g of butyl acrylate and 150 g of xylene. The contents of the flask were heated to a temperature of 90-100 ° C and then 2 g of benzoyl peroxide was added. After the reaction mixture was kept at this temperature for 4 hours, another 1 g of benzoyl peroxide was added. Benzoyl peroxide was added 2 more times in 1 g every two hours after completion of the reaction. After that, the contents of the flask were cooled and then 100 g of xylene added to obtain a 50% polymer solution. The glass transition point of the obtained polymer was -45 ° C.

Example II

150 g of xylene were placed in a flask equipped with a reflux condenser, stirrer and thermometer. A mixed solution consisting of 175 g of butyl acrylate, 50 g of butyl methacrylate, 25 g of styrene and 1 part of benzoyl peroxide was added dropwise to the contents of the flask over 2 hours while keeping the temperature at 90 to 100 ° C and then 1 g of benzoyl peroxide 3 added times at 2 hour intervals to terminate the polymerization reaction. The contents of the flask were then cooled and 100 g of xylene added to obtain a 50% polymer solution. The glass transition point of the obtained polymer was -20 ° C.

S 5 ö 2 3 5 2 -7- 24947 / Vk / mvl

Example III

150 g of xylene were placed in a flask fitted with the same equipment as in Example II. A mixed solution consisting of 190 g of ethyl acrylate, 50 g of ethyl methacrylate, 10 g of 2-hydroxyethyl-5 methacrylate together with 1 g of benzoyl peroxide was added dropwise to the flask for 2 hours keeping the temperature at 90 to 100 ° C and then 1 g of benzoyl peroxide added 3 times at 2 hour intervals to terminate the polymerization.

The contents of the flask were then cooled and 100 g of xylene added to obtain a 50% polymer solution. The glass transition point of the obtained polymer was -2 ° C.

Example IV

Final compositions which can be used as paint for the hull of a ship with blend ratios as shown with blends 1-7 listed in Table A were prepared from 50% polymer solutions obtained through Examples I to III, a resin solution which is marketed under the trade name VIOMET 300 (50% solution of a copolymer of methyl methacrylate and tributyltin methacrylate prepared by Μ & T Co., Ltd. with a glass transition point of 0 ° C) and VIOMET 303J (50% solution of a copolymer of methyl methacrylate, octyl acrylate and tributyltin methacrylate prepared by Μ & T Co., Ltd. with a glass transition point of 8 ° C}.

Thereafter, the sealing compositions based on the above-mentioned mixtures 1-7 were applied in a film with a dry thickness of about 50 µm thick on a dirt-repellent paint containing acrylic resin as the main carrier, applied to an iron plate on which an anti-rust paint was first applied and the drying state and surface condition of the applied film were examined.

The results are shown in Table B. In addition, Table B showed that the barrier compositions of the present invention were superior to the conventional first coat as shown in the comparative examples. Furthermore, although a soil repellant paint was applied to the dried barrier compositions, the undercoat formed from the soil repellant paint did not soften. Furthermore, it was found that even when a coal tar epoxy paint was applied to these barrier compositions, they softened to a lesser extent than in the comparative examples.

From the data of Tables A and B, it appears that the use of the sealing compositions applicable to the hull of a ship of the present invention containing acrylic resin having a glass transition temperature of 10 ° C or less in an amount of 10 to 70 wt. %, results in an excellent applied coating and drying state for the applied film.

This shows that according to the invention a sealing composition has been obtained which can be used for painting the hull of ships. Such a paint includes an anti-corrosive paint 10 which inhibits corrosion and a dirt-repellent paint. The combined use of an anti-corrosive paint and a soil repellant paint has presented problems and these have now been overcome by choosing a composition containing at least one of the polymers based on monomers. expressed by the general formula mentioned below or a vinyl group to give an acrylic resin having a glass transition point of 10 ° C or less, which acrylic resin is used in an amount of 10 to 70% by weight in the barrier composition, which formula corresponds to f '20 ch 2 = c-coor 2 where hydrogen is or a methyl group, R 2 is hydrogen or alkyl, hydroxyalkyl, aminoalkyl, alkoxyalkyl, organic tin or organic lead group having 1 to 20 carbon atoms.
