The present invention relates to an underwater paint used for on-site corrosion protection of marine structures, etc. More specifically, the present invention relates to an underwater paint that adheres firmly to the surface of steel materials under adverse corrosive conditions such as seawater or alkali-contaminated water. The present invention relates to an underwater paint that is capable of forming a coating film having properties. As for paints for underwater painting, a lot of research and development has been done and various products have actually been put on the market, but most of them are based on epoxy resins. Epoxy resin-based paints can be used satisfactorily if the coating operation is carried out under freely controllable conditions (i.e., when preliminary operations such as polishing and cleaning of the surface to be coated are complete or close to complete). Although it can demonstrate its original adhesion strength and provide a strong coating film, for example, in water, especially in seawater where there are contaminants such as various salts and other contaminants, the coating may not adhere to the steel surface to be coated. It is difficult to uniformly form a paint film on the steel surface during painting, which not only causes extremely low construction efficiency, but also requires that the reliability of the paint film after construction is sufficiently high. It was impossible. Due to these circumstances, when actually performing painting work under the sea, the coating is applied by a method such as wrapping a plastic net around the object to be painted and rubbing putty-like epoxy resin paint over it. However, there are still questions about the adhesion of the paint to the object to be painted, and there have been many reports of concrete cases where the paint film has lifted or peeled off. Conventional paints for underwater painting can be expected to give some results under conditions where the object to be painted is wet, but as mentioned above, they are extremely insufficient under water, and the paint components may not be absorbed into the water. Nowadays, there is a demand for the use of paints that do not contain organic solvents in order to suppress the elution and dispersion of water and to prevent water pollution as much as possible.However, conventional solvent-free epoxy resin paints for underwater painting have extremely high viscosity and are difficult to work with. The problem is that the pot life (the pot life of the paint after mixing the curing agent) is extremely short. For this reason, it is generally necessary to use a special mixing mixer for paints, and requires a great deal of labor at the construction site, resulting in poor efficiency. The present invention has been made as a result of various studies on underwater curing paints that eliminate the above-mentioned disadvantages, and has resulted in an underwater curing paint that can be easily applied and has a sufficiently reliable coating film after painting. be. That is, the present invention provides a solvent-free paint having a specific gravity of 1.5 to 2.0 and containing 0.5 to 5.0% by weight of a polycarboxylic acid amine salt having 8 to 12 carbon atoms and having a hydrophobic polyoxyalkylene group having 8 to 12 carbon atoms. The present invention relates to an underwater curing paint characterized by being composed of a two-component mixed epoxy/polyamine paint. The epoxy resin used in the present invention is most commonly a liquid bisphenol glycidyl ether type epoxy resin with a molecular weight range of approximately 350 to 420, but other types include low viscosity modified bisphenol A type epoxy resin, bisphenol One type or a mixture of two or more types selected from F-type epoxy resins, aliphatic epoxy resins, etc. may be used. A diluent is used separately for the epoxy resin as described above. Specifically, the diluents used here are reactive ones selected from aliphatic glycidyl ethers and aromatic glycidyl ethers, and non-reactive ones selected from petroleum-based aromatic polymerized oils. , this is 1 type or 2 types as necessary.
It is also possible to use a combination of more than one species. The epoxy resin and diluent described above form the base of a two-component curing paint, but whether or not the blended paint can be cured underwater for underwater painting depends on the type of curing agent rather than the paint base itself. Therefore, it is greatly affected. Polyamines with active hydrogen are usually used as curing agents for epoxy resin paints, but many of these polyamines are water-soluble or partially water-soluble and cannot be used in the situation targeted by the present invention, that is, in water. As a result of elution and diffusion, the coating film may not be cured, or even if it is cured, sufficient strength cannot be expected because there is little amine that contributed to the reaction. Therefore, as a matter of course, it is necessary to be insoluble in water, or at least have a low solubility that does not dissolve out until the curing reaction is completed, and the material must be selected from within such a limited range. However, an element that satisfies the following conditions is also required. 1. The specific gravity of the underwater curing paint is higher than that of water or seawater, specifically 1.5 to 2.0. Underwater curing paints are often used to repair the inner surfaces of water pipes with high flow speeds and marine structures installed in seawater with waves.
If the specific gravity of the paint is about the same or slightly higher than that of water or seawater, even if underwater painting is performed, a phenomenon occurs in which the paint film lifts up from the painted surface due to the water flow and eventually peels off. 2. To lower the surface tension of the paint and give it acidity. The most important thing about underwater curing paints is the "wettability" of the paint to the painted surface, which can be determined by the surface tension of the paint. The environment in which underwater curing paints are used is underwater or seawater, and it is usually impossible to perform pretreatment before painting. Iron hydroxide is formed on the surface of the object to be painted (mostly steel surfaces), and it is alkaline and has a "slimy" state. Because the surface tension of paint is high, it usually does not blend well with the target steel surface. Among the above two conditions, the specific gravity of the underwater curing paint can be adjusted by changing the amount of filler used. Materials used for this purpose include talc, barite, calcium carbonate, calcium silicate, talcum powder, clay, and silica sand, and any one of these may be selected and used as required. Also, substances that lower the surface tension of paint and give it acidity include alkyl, allyl, polyglycol, and ether. Aliphatic amine salt R′R″RNX where R, R′, R″, R: alkyl group, ~12 polycarboxylic acid amine salts are used. This one is 0.5 ~
When used in a weight range of 5.0%, good paintability and adhesion of the coating film can be obtained as shown in the examples below. In this case as well, a surfactant that is insoluble or sparingly soluble in water is used, as a matter of course, for the same reason as in the case of the curing agent. The present invention will be explained in more detail below using Examples. Example 1 Bisphenol A type epoxy resin (GY250,
(manufactured by Ciba Geigy, trade name), non-reactive diluent (SAS-296, manufactured by Nippon Petrochemicals, trade name), talc, red iron, barite, polyoxyalkylene group having 8 to 12 carbon atoms.

The adhesion of the coating film after curing was observed and the results shown in the following table were obtained.

It was observed that paint adhesion was significantly improved. Example 2 In order to repair the underwater immersion part and splash zone of the seawall pile made of steel pipe piles that had already been installed, the underwater curing paints A to D prepared in Example 1 were applied to the steel pipe piles. Prior to the coating operation, rust removal treatment was performed using a power tool, and the coating was applied by hand while wearing work gloves. The pH of the seawater was around 9, probably due to the input of sediment or pollution. As a result of the coating test, A did not adhere to the pile at all, while C and D had good paintability, no paint was observed to flow out due to waves, and both coating adhesion and strength after curing were good. .
