The present invention relates to a synthetic resin compound paint that has both the functions of a rust preventive paint and a top coat, that is, has a rust preventive effect and can be coated in a thick film. Traditionally, pipes, tanks, buildings, bridges,
When painting iron structures such as ships, first prepare the base surface of the iron part to give it a metallic luster by using Type 1 or Type 2 staining, and then apply oil-based alkyd resin-based rust prevention paint. like JIS
1-2 general-purpose anti-rust paints based on K-5621
Paint so that the film thickness is approximately 35μ to 70μ,
Furthermore, a synthetic resin compound paint based on JIS K-5516, such as an oil-based alkyd resin top coat paint, is applied once or twice to a film thickness of about 25 to 50 microns. That is, the anti-rust paint provides rust prevention, and the top coat paint provides aesthetics and durability such as water resistance and weather resistance. Therefore, when painting with the conventional paint system described above, it is necessary to first carefully prepare the substrate, and then apply two coats of paint, one coat of anti-rust paint and one coat of top coat. In order to increase the properties or to increase the hiding power and improve the aesthetic appearance, it was necessary to increase the number of times each coat was applied. As a result of intensive research, the inventor of the present invention aimed to simplify the preparation of the substrate as much as possible and further reduce the number of coats as much as possible in the above-mentioned coating system. The present invention has been completed by discovering a synthetic resin compound paint that can be coated with three types of stains, and can be applied to a thick film of about 60μ in one coat, and has both the functions of conventional rust-preventing paint and top coat paint. . That is, the present invention provides a synthetic resin composition paint that includes: (A) a phosphate-based or molybdate-based rust-preventing pigment;
0.5 to 5% by weight, (B) at least one unsaturated fatty acid selected from the group consisting of ethyl oleate, methyl linoleate, ethyl linoleate, methyl linolenate, ethyl linoleate, butyl linolenate, and ethyl elaidate. Contains 0.5 to 2% by weight of ester and (C) 0.3 to 1% by weight of a polyamide-based thixotropic agent obtained by reaction of a C 16 to 20 fatty acid with a polyamine, and has a pigment volume concentration (PVC) of 20%.
It provides a synthetic resin compound paint that can be used as a rust preventive and top coat with ~35%. The above component (A) used in the present invention is used to impart a rust-preventing effect to the paint film.It has a rust-preventing effect in a small amount, does not adversely affect the gloss of the top coat, and has low toxicity. It is a non-polluting, rust-preventing pigment.
Phosphate-based antirust pigments include zinc, calcium,
Ortho and condensed phosphates such as magnesium, titanium, and silicon are mentioned, and molybdate-based rust-preventive pigments include zinc molybdate, calcium molybdate, zinc calcium molybdate,
Examples include potassium zinc molybdate, aluminum molybdate, and aluminum phosphomolybdate. These anti-rust pigments should be contained in the range of 0.5 to 5% by weight in the entire paint.If the content is less than 0.5% by weight, the rust-preventing effect will not be exhibited;
If the amount exceeds 1% by weight, the gloss of the coating film will be significantly reduced, which is not preferable. The above-mentioned component (B) used in the present invention is for preventing the occurrence of rust, and penetrating into the generated rust to solidify the rust or prevent the progress of rust. Examples of the ester include at least one unsaturated fatty acid ester selected from the group of ethyl oleate, methyl linoleate, ethyl linoleate, methyl linolenate, ethyl linolenate, butyl linolenate, and ethyl elaidate. These unsaturated fatty acid esters are present in all paints.
It is contained in the range of 0.5 to 2% by weight, and if the content is less than 0.5% by weight, rust prevention cannot be achieved.
On the other hand, if it exceeds 2% by weight, it is not preferable because the drying properties and weather resistance of the coating film decrease. The above component (C) used in the present invention can be used in one application.
This is to prevent problems such as sagging even when a thick film of about 60μ is applied, and examples of such thixotropic agents include polyamide-based thixotropic agents made by reacting C 16 to 20 fatty acids with polyamines, such as Disparon #6900- 20X (Kusumoto Kasei Co., Ltd. product name),
Examples include Talen #7200-20 (trade name of Kyoeisha Yushisha Co., Ltd.). These xixotropic agents are present in 0.3% of the total paint.
The content is in the range of ~1% by weight.
If it is less than 0.3% by weight, problems such as sagging will occur when a thick film is coated in one coat, and if it exceeds 5% by weight, it will reduce the gloss of the coating, which is undesirable. In addition to the above-mentioned components (A) to (C), the paint of the present invention also contains long-oil alkyd resins used in synthetic resin compound paints based on JIS K-5516, or their vinyl, urethane, phenol, epoxy, etc. The base vehicle resin component such as modified resin is an essential component, and furthermore, color pigments such as titanium oxide, Bengara, cyanine blue, yellow lead, carbon black, calcium carbonate, clay, precipitated barium sulfate, etc. Auxiliary agents such as a pigment mineral turpentine, a solvent such as Swasol #310, a drying accelerator such as aluminum alcoholate, a dryer, a pigment dispersant, and an anti-scaling agent can be contained. Furthermore, the paint according to the present invention may contain other pigments such as anti-corrosive pigments, coloring pigments, and extender pigments in addition to the anti-rust pigment (A), but these pigment volume concentrations (PVC) If PVC is contained in the range of 20% to 35%, if the PVC content is less than 20%, the rust prevention ability of the paint film will decrease or a sagging phenomenon will occur, whereas if it exceeds 35% is undesirable because it reduces the gloss of the coating film and its permeability to rusted surfaces. The paint of the present invention can be prepared by uniformly mixing and dispersing the above-mentioned components using a sand mill or the like using a conventional paint manufacturing method, and can be applied by an appropriate method such as a brush, a roller, or an airless spray. The paint of the present invention contains specific amounts of components (A) to (C) as described above, and further contains pigments such that PVC falls within a specific range, making it possible to improve the coating system of conventional synthetic resin compound paints. Man-hours such as substrate preparation and number of times of painting can be significantly reduced. The present invention will be explained below with reference to Examples. Examples 1 to 3 and Comparative Examples 1 to 6 Paints of Examples 1 to 3 and Comparative Examples 2 to 6 were prepared by uniformly mixing and dispersing the components shown in Table 1 using a sand mill. Further, as the paint for Comparative Example 1, a commercially available rust-preventing paint (quick-drying rust-preventing paint K-21: Shinto Paint) and a synthetic resin blend paint (SP Pain Sakura D: Shinto Paint) as a top coat were used. The paint of each of these examples was applied with a brush to a rusted steel plate from which floating rust and the like had been removed with sandpaper, and the performance of the paint film was tested. The results are shown in Table 1.
