The present invention relates to a coating composition for preventing corrosion, coloring, and anti-slip surfaces of so-called galvanized steel towers, such as power transmission towers and microwave towers, which are coated with galvanized steel, particularly hot-dip galvanized coatings. Conventionally, galvanizing has been applied as a long-term corrosion protection method for steel materials and steel products, and it is well known that large structures such as power transmission towers and microwave towers are coated with hot-dip galvanizing. It is like that. This corrosion prevention method is far superior to general paint coating methods, but as air and water pollution has progressed recently, zinc has been depleted significantly, and the long-term corrosion prevention effect is no longer as good as before. The current situation is that we cannot expect much. In order to make the long-term corrosion protection inherent in galvanized plating effective, it is necessary to have an organic coating on the galvanized surface to prevent contact with anti-corrosion factors such as water and the atmosphere. As structures have recently become larger in size, there has been a strong demand for colored and aesthetically pleasing structures for reasons of necessity as aviation beacons or from the aesthetic point of view of harmonizing with the environment. For the reasons mentioned above, oil-based paints or synthetic resin-based paints are currently applied to galvanized surfaces. However, this type of paint has the disadvantage that the paint film peels off and separates from the surface of the galvanized layer at an early stage, and is not always satisfactory. Furthermore, as structures become larger, it becomes difficult to repaint for maintenance, so long-term durability and
From the viewpoint of color retention, the use of synthetic resin paints such as tar epoxy resin paints, tar urethane resin paints, unsaturated polyester resin paints, epoxy resin enamels, and polyurethane resin enamels is being considered. However, all of these had poor adhesion. On the other hand, it is common for people to go up and down power transmission towers for maintenance and inspection purposes, but because the coating film obtained from conventional paint compositions is smooth, it is easy to slip when going up and down, which is a big problem. It was hot. The present invention aims to eliminate or improve the drawbacks of conventional paints as described above, and has excellent adhesion to galvanized power transmission towers.
The object is to provide a coating composition with excellent anti-slip properties. That is, the present invention provides: (1) (a) an epoxy resin composition containing at least two or more epoxy groups at the end and at least one or more hydroxyl group at the side chain...100 parts by weight, (b) an oxyacid acid salt and at least one compound selected from metal oxides...1 to 250 parts by weight, and (c) aggregate...10 to 500 parts by weight, and (2) ( a) Epoxy resin composition containing at least two or more epoxy groups at the end and at least one or more hydroxyl group at the side chain...100 parts by weight, (b) Metallic zinc powder and/or calcium leadate
...10 to 200 parts by weight, (c) at least one compound selected from oxyacid salts and metal oxides ...1 to 150 parts by weight, and (d) aggregate ...10 to 500 parts by weight , relates to a coating composition for power transmission towers comprising: The epoxy resin composition used in the present invention consists of a mixture of an epoxy resin containing at least two epoxy groups at the end and at least one hydroxyl group in the molecule, and a crosslinking agent. Examples of the epoxy resin include linear bisphenol epoxy resins, methyl-substituted bisphenol epoxy resins, and side chain bisphenol epoxy resins. Examples of commercially available product names include Epicort (trade name manufactured by Ciel Chemical Co., Ltd.), Epicron (trade name manufactured by Dainippon Ink and Chemicals Co., Ltd.), and Araldite (trade name manufactured by Ciba Geigy Co., Ltd.). This is a typical example. These can be used alone or in combination of two or more to bring out the characteristics of each. As the crosslinking agent of the present invention, any crosslinking agent that has a group that reacts with the epoxy group or hydroxyl group contained in the epoxy resin molecule and is generally used as a crosslinking agent for epoxy resins may be used. For example, aliphatic or aromatic polyamines such as diethylenetriamine, triethylenetetramine, metaxylylenediamine, metaphenylenediamine, heterocyclic diamine, dimethylaminomethylphenol, tris(dimethylaminomethyl)
Secondary or tertiary substances such as phenol and piperidine
Amino compounds such as grade amines, polyamide resins, amine adducts (generally referred to as amine adducts), isocyanate compounds such as tolylene diisocyanate and hexamethylene diisocyanate, as well as phenolic resins, acid anhydrides, melamine resins, urea resins, etc. are mentioned. Since the object of the present invention is a large structure called a power transmission tower, the chemical reaction between the epoxy resin and the crosslinking agent proceeds at room temperature or forced drying, and amino compounds that involve a chemical reaction with epoxy groups are the most effective. preferable. As will be described later, the feature of the present invention is that at least one component selected from oxyacid salts and metal oxides contained in the composition chemically reacts with the galvanized surface and imparts adhesion to the coating film. There is a particular thing. In particular, when phosphate is an essential component and is used in combination with at least one component selected from other oxyacids and metal oxides, phosphoric acid and epoxy resin are bonded together via metal ions. This is preferable because it forms a chelate bond with the hydroxyl group of the compound, thereby providing the effect of imparting strong adhesion. Therefore, when mixing the epoxy resin and crosslinking agent of the present invention, if the crosslinking agent has a property that involves a chemical reaction with the hydroxyl group in the epoxy resin molecule, the amount of crosslinking agent relative to the epoxy resin should be adjusted to 1% of the epoxy resin. 0.9 to equivalent weight
It is preferable to adjust the amount to about 0.5 equivalent so that some of the hydroxyl groups in the epoxy resin molecules remain. Oxylate salts used in the present invention include chromic acid, phosphoric acid (including condensed phosphoric acid), boric acid, molybdic acid, phosphomolybdic acid, silicomolybdic acid, tungstic acid, phosphotungstic acid, silicotungstic acid, etc. It is a salt consisting of an oxygen acid and various metals. For example, strontium chromate, calcium chromate, lead chromate, zinc chromate, zinc chromate, zinc molybdate, calcium molybdate, zinc tungstate, calcium tungstate, magnesium tungstate, zinc phosphate, lead orthophosphate, lead pyrophosphate, Lead metaphosphate, aluminum phosphate, tin orthophosphate,
tin pyrophosphate, tin oxyphosphate, zinc tetraborate,
Zinc metaborate, lead metaborate, lead tetraborate, barium metaborate, etc. can be used. The metal oxides used in the present invention are oxides of chromium, molybdenum, tungsten, manganese, etc. For example, chromium trioxide, molybdenum trioxide, tungsten trioxide, manganese dioxide, etc. can be used. These oxyacid salts and metal oxides described above can be used alone or in a mixture in any proportion. In particular, the phosphate is an essential component,
When used in combination with at least one component selected from other oxyacids or metal oxides other than phosphates, the phosphoric acid produced by hydrolysis will cause epoxy oxidation through the metal ions in the oxyacids or metal oxides. Since it is thought that a chelate compound is formed with the hydroxyl group in the resin, the use of that combination is most preferred. The amounts of the oxyacid salts and metal oxides used in the present invention vary depending on their reactivity to the galvanized surface, corrosion resistance, etc., and vary accordingly, but 100 parts by weight of the epoxy resin Use the following amounts for: That is, when metal zinc powder and/or calcium leadate, which will be described later, are used in combination, the amount is 1 to 150 parts by weight, preferably 5 to 100 parts by weight, based on 100 parts by weight of the epoxy resin composition. When using only at least one compound selected from metal oxides, the amount is 1 to 250 parts by weight, preferably 10 to 120 parts by weight, based on 100 parts by weight of the epoxy resin composition.
Use within the range of parts by weight. In the above range, if the amount of the oxyacid salt or metal oxide is less than 1 part by weight, no chemical conversion film formation effect or chelate formation effect on the galvanized surface can be expected. On the other hand, if the amount of the oxyacid or metal oxide exceeds 150 or 250 parts by weight, the adhesion of the coating film to the galvanized surface tends to be impaired. In the present invention, it is most effective to use phosphate as an essential component in combination with at least one component selected from other oxyacids and metal oxides other than phosphate. As mentioned above, in this case, the preferred mixing ratio of phosphate and other oxyacid salts and metal oxides is 95 to 30% by weight for the former and 5 to 70% by weight for the latter. %. Examples of the aggregate used in the present invention include those commonly called aggregates such as sand, gravel, silica sand, emery, and glass beads, and these may be used alone or in combination of two or more. can. This component imparts appropriate roughness to the surface of the coating layer and enhances the anti-slip effect. The aggregate component is used in an amount of 10 to 500 parts by weight, preferably 50 to 300 parts by weight, based on 100 parts by weight of the epoxy resin composition. In the above range, if the amount used exceeds 500 parts by weight, the surface roughness of the coating film will be too large, and there will be a tendency for foaming when overcoating, and the adhesion of the coating film will decrease. When the amount is less than 1 part by weight, there is no effect of imparting roughness to the surface of the coating film, and there is no anti-slip effect at all. In another embodiment of the present invention, at least one component selected from metal zinc powder and calcium leadate is used, but any component commonly used for paints may be used. The amount of this component added to 100 parts by weight of the epoxy resin composition is 10 to 200 parts by weight, preferably 30 to 150 parts by weight. The effect of the metal zinc powder and calcium leadate of the present invention is to further stabilize and sustain the long-term adhesion of the coating film, and it has a buffering effect between the galvanized surface and the coating film, which has the effect of promoting adhesion. It is considered to be something that gives. In the present invention, the use of calcium leadate alone or in combination with calcium leadate and metal zinc powder has a great effect on maintaining adhesion. When using the two types in combination, the mixing ratio of calcium leadate and metal zinc powder is 80 to 40% by weight for the former and 80 to 40% by weight for the latter.
20-60% by weight is most effective. If the amount of at least one component selected from metal zinc powder and calcium leadate of the present invention is less than 10 parts by weight, there will be no sustained effect on coating adhesion, and if it is more than 200 parts by weight, the adhesion will tend to be impaired. As described above, the present invention comprises an epoxy resin composition, metal zinc powder, at least one component selected from calcium leadate, at least one compound selected from oxyacid salts, and metal oxides, and the above amount of each. By using a composition with a specific ratio, it has strong adhesion to the galvanized coating surface,
Moreover, it is possible to obtain a coating film whose effect lasts for a long period of time, and the aggregate imparts strong adhesion to the surface of the galvanized coating and provides an anti-slip effect. In the present invention, in addition to the above-mentioned essential components, it is also possible to add other resins that are compatible with the above-mentioned composition within a range that does not impair the object of the present invention.
Furthermore, if desired, other anti-rust pigments, extender pigments such as talc and silica, coloring pigments such as iron oxide, carbon black and titanium oxide, asphalt, tar,
Additives such as bituminous substances such as pitch, anti-settling agents, anti-sag agents, surfactants, surface conditioners, coupling agents, chelate compounds, solvents, etc. to further enhance the adhesion of the coating film. I can do it. In addition, when an organic solvent system other than water is used as a solvent in the present invention, at least one kind of alcohol is used to assist in the elution or hydrolysis of metal ions of oxyacid salts and metal oxides in the composition. It is preferable that the composition contains about 3% by weight or less of water based on the system solvent or solvent. The coating composition comprising the above-mentioned components of the present invention is applied to a galvanized surface by a known method such as a brush, spray, roller, spatula, trowel, etc. to obtain a dry film thickness of about 10 to 1000 microns, A coating film having the above effects can be obtained by causing a chemical reaction between the epoxy resin and the crosslinking agent and curing the coating film under conditions necessary for drying the coating film.
Depending on the use and purpose of the steel tower, paints of various colors such as polyurethane resin paint, epoxy resin paint, chlorinated rubber paint, vinyl chloride resin paint, etc. can be applied to a thickness that does not lose the anti-slip effect of the present invention. It is possible to apply an overcoat, or to apply the composition of the present invention on a previously applied epoxy resin-based or polyurethane resin-based primer. The coating film obtained from the coating composition of the present invention exhibits strong durability against long-term exposure, and has stable adhesion over a long period of time without peeling or detaching in a short period of time as in the case of conventional coatings. It has an anti-slip effect. Next, specific effects of the present invention will be shown by examples.
In addition, "part" or "%" in Examples and Comparative Examples means "part by weight" or "% by weight". Example 1 A linear bisphenol type epoxy resin with an epoxy equivalent of 450 to 500 and an active hydrogen equivalent of 150 as a crosslinking agent.
