The present invention relates to a novel water-dispersible coating composition for metal corrosion protection. More specifically, the present invention relates to a water-dispersed anticorrosion coating composition containing a water dispersion of a specific chelate-reactive epoxy resin and an active organic curing agent. A paint composition that has excellent adhesion and corrosion resistance to not only rust-free copper plates and derusted steel plates, but also rusted steel plates or poorly prepared steel plates, galvanized steel plates, aluminum, stainless steel, etc. It is related to. Conventional water-dispersed epoxy resin paints have significantly inferior adhesion and especially corrosion resistance compared to solvent-based epoxy resin paints, and cannot be used as metal protection paints for rust prevention purposes, and are mainly used as mastic paints for building materials. is the main use. The purpose of the present invention is to provide a resin composition for a water-dispersed epoxy resin paint that has excellent adhesion to metals and corrosion resistance, and the present inventors have made extensive efforts for this purpose. As a result of research, we have arrived at the present invention. That is, the coating composition of the present invention contains (A) one or more P-OH bonds selected from orthophosphoric acid, metaphosphoric acid, pyrophosphoric acid, phosphorous acid, polyphosphoric acid, phosphonic acid, and phosphinic acid as an essential component. (B) an aqueous dispersion of a resin that can be cured with an epoxy resin curing agent obtained by heat-treating at least one phosphorus acid, ester or salt thereof, and an epoxy resin in a proportion that leaves epoxy groups; It is characterized by containing an active organic curing agent for epoxy resin. The precondensate, which is an essential component of the composition of the present invention, is a mixture of an epoxy resin and a phosphoric acid, a hydroxyl group-containing phosphate ester, or a salt thereof in the presence of a solvent or in a proportion that leaves the epoxy group. Obtained by heat treatment in its absence. The heating temperature is not particularly limited, but it is preferably 50 to 130°C in order to prevent decomposition of the epoxy resin and to complete the reaction in an appropriate time. The epoxy resin used here has the formula

[Table] Example 5 28 parts of sodium pyrophosphate was mixed with 100 parts of bisphenol A diglycidyl ether (epoxy equivalent = 380) and reacted at 80°C for 5 hours to obtain a precondensate [ ] (epoxy equivalent =755). An epoxy emulsion was obtained in the same manner as in Example 1 using 100 parts of the precondensate, and 15 parts of polyamide (amine value = 340) was added as an epoxy resin curing agent, and coating film performance was evaluated in the same manner as in Example 1. Examined. The results are shown in Table 2. Example 6 5 parts of phosphorous acid was mixed with 100 parts of bisphenol F diglycidyl ether (epoxy equivalent = 480) and reacted at 80°C for 5 hours to obtain a precondensate [ ] (epoxy equivalent = 755) . An epoxy emulsion was obtained in the same manner as in Example 1 using 100 parts of the precondensate [], and a modified aromatic amine Adeka hardener EH-541S (amine value =
280 (trade name, manufactured by Asahi Denka Kogyo Co., Ltd.) was added, and the coating film performance was examined in the same manner as in Example 1. The results are shown in Table 2. Example 7 Add adeca glycilol to 100 parts of bisphenol A diglycidyl ether (epoxy equivalent = 380)
Mix 2 parts of polyphosphoric acid with 20 parts of ED-501 (epoxy equivalent = 300, product name manufactured by Asahi Denka Kogyo Co., Ltd.) and heat at 80°C x 5
The reaction was carried out for a period of time to obtain a precondensate (epoxy equivalent = 850). An epoxy emulsion was obtained in the same manner as in Example 1 using 100 parts of the precondensate, and 15 parts of polyamide (amine value = 340) was added as an epoxy resin curing agent, and coating film performance was evaluated in the same manner as in Example 1. Examined. The results are shown in Table 2. Example 8 100 parts of bisphenol F diglycidyl ether (epoxy equivalent = 480) and adeca glycilol
Mix 3 parts of phosphonic acid with 20 parts of ED-501 (epoxy equivalent = 300, trade name manufactured by Asahi Denka Kogyo Co., Ltd.) and heat at 80°C x 5
The reaction was carried out for a period of time to obtain a precondensate (epoxy equivalent = 770). An epoxy emulsion was obtained in the same manner as in Example 1 using 100 parts of the precondensate, 17 parts of polyamide (amine value = 340) was added as an epoxy resin curing agent, and coating film performance was evaluated in the same manner as in Example 1. Examined. The results are shown in Table 2. Example 9 3 parts of phosphinic acid was mixed with 100 parts of bisphenol A diglycidyl ether (epoxy equivalent = 380) and reacted at 80°C for 5 hours to form a precondensate []
was obtained (epoxy equivalent = 710). An epoxy emulsion was obtained in the same manner as in Example 1 using 100 parts of the precondensate, 18 parts of polyamide (amine value = 340) was added as an epoxy resin curing agent, and coating film performance was evaluated in the same manner as in Example 1. Examined. The results are shown in Table 2. Comparative Example 5 475 parts of bisphenol A diglycidyl ether (epoxy equivalent = 475) was mixed with 28 parts of orthophosphoric acid and 250 parts of methyl ethyl ketone, and the mixture was reacted at 70°C for 20 hours until the oxirane group content became 0 to form a precondensate. [] was obtained (acid value 40 mg, KOH/g). An emulsion was obtained in the same manner as in Example 1 using 100 parts of the precondensate.
5 parts of triethylenetriamine was added to each part, and the coating film performance was examined in the same manner as in Example 1. The results are shown in Table 2. Comparative Example 6 100 parts of bisphenol A diglycidyl ether (epoxy equivalent = 380) was mixed with 3 parts of 1-hydroxyethane-1,1-diphosphoric acid and reacted at 80°C for 5 hours to form a precondensate [XI] was obtained (epoxy equivalent = 502). An epoxy emulsion was obtained in the same manner as in Example 1 using 100 parts of precondensate [XI], 23 parts of polyamide (amine value = 340) was added as an epoxy resin curing agent, and coating film performance was evaluated in the same manner as in Example 1. I looked into it. The results are shown in Table 2. Comparative Example 7 100 parts of bisphenol A diglycidyl ether (epoxy equivalent = 380) and 20 parts of dibasic potassium phosphate
The two parts were mixed and reacted with stirring at 100°C for 5 hours to obtain a precondensate [XII]. An epoxy emulsion was obtained in the same manner as in Example 1 using 100 parts of precondensate [XII], 3 parts of polyamide (amine value = 340) was added as an epoxy resin curing agent, and a coating film was formed in the same manner as in Example 1. I created it, but 1
It did not harden even after being left at room temperature for a week.
