Detailed Description of the Invention The present invention is used as a protection material for civil engineering and architectural structures, as a long-term rust prevention material for steel structures such as ships, bridges, and tanks, and as a waterproofing material for rooftops and underground tanks. This is a protective coating composition used as a lining material on surfaces, as a protective material for paint films, and as a lining material for surfaces. Epoxy resin emulsions and ethylene vinyl acetate copolymer emulsions can be mixed in any ratio and a stable emulsion can be obtained, but a curing agent must be added each time it is used, which is difficult to handle. Ethylene-vinyl acetate copolymer emulsions also have the property of forming a film upon evaporation of water and re-emulsifying in warm water.

もの、柔軟性のあるものが得られる。In the present invention, an epoxy curing agent and a crosslinking additive are added to a mixed emulsion, and as water and a reaction inhibitor evaporate, the curing agent and crosslinking additive act to improve water resistance, chemical resistance, and weather resistance. A coating material with excellent flexibility and flexibility can be obtained. In particular, when a hardening agent is blended into a thermosetting resin such as an epoxy resin, the reaction of the base resin begins, the viscosity increases in a short period of time, and it finally becomes a solid. By dissolving it in a solvent rich in lipophilic groups such as an aromatic solvent and dispersing it in an emulsion, the curing reaction is suppressed. Therefore, the curing reaction begins only when the solvent evaporates. Furthermore, when iron or aluminum containing trivalent ions is added as a crosslinking agent to an ethylene vinyl acetate copolymer emulsion, a film that does not re-emulsify is formed. However, it is difficult to mix the crosslinking agent in one solution and store it for a long period of time, but in the present invention, ethylene glycol and
When propylene glycol is added and sufficiently stirred, crosslinking with trivalent metal ions is suppressed by a thin film of ethylene glycol and propylene glycol on the surface of the emulsion particles. When two different thermosetting resins and thermoplastic resins are mixed together with a curing agent and a crosslinking additive in the same liquid, the reaction between the curing agent and the crosslinking additive occurs during the film formation that occurs as water and solvent evaporate. simultaneously proceed to form an excellent protective coating. Furthermore, by blending and combining epoxy resin and ethylene vinyl acetate resin, products with adhesive strength and flexibility can be obtained.

る。The present invention utilizes a lipophilic solvent and a hydrophilic glycol as a reaction repellent and inhibitor in an emulsion,
Moreover, it was discovered that it acts as a reaction control agent. In particular, by selecting a highly lipophilic solvent, the reaction can be stopped for a long period of time in the emulsion. In addition, trivalent ion metals, especially iron oxide used in ferrite, improve the durability of ethylene-vinyl acetate copolymer resins and promote the bonding of resin molecules so that they can withstand alkalis, acids, and solvents.

Moreover, by blending the paint mixture and aggregate, it has good adhesive properties. Creates a strong protective coating. In particular, the addition of ferrite forms a film that is weather resistant for over 10 years.
As time passes, the characteristics of both will be fully demonstrated.
