Definitions

  • the present invention relates to an anticorrosion paint composition that does not contain tar, and is particularly useful for painting the interior of ships such as ballast tanks.
  • tar epoxy filler has been used as an anticorrosive paint for ships and structures.
  • the paint is excellent in anticorrosion, water resistance, shochu chemical properties, etc., but since it contains tar, only the safety and hygiene problems are conceived due to the benzpyrene, a pain-causing substance contained in tar. In addition, it was difficult to maintain because it was amber, and it became too long in a closed place.
  • the present inventors have conducted intensive studies to solve the above problems, and as a result, by using a specific amount of a hydroxyl group-containing petroleum resin or a specific cracking residual oil instead of tar, the compatibility with the epoxy resin and the amine-based curing agent has been improved.

  • Known ones such as a monoacid-modified epoxy resin may be mentioned, and these may be used alone or in combination of two or more.
  • Examples of the amine curing agent (B) used in the present invention include conventionally known curing agents for epoxy resins, for example, aliphatic acids such as metaxylenediamine, isophoronediamine, diethylenetriamine, triethylenetetramine, and diaminodiphenylmethane.
  • aliphatic acids such as metaxylenediamine, isophoronediamine, diethylenetriamine, triethylenetetramine, and diaminodiphenylmethane.

If the content is less than 1 mol per molecule, the compatibility with the above-mentioned amine-based curing agent is reduced and the coating film performance is adversely affected. On the other hand, if it exceeds 2 mol, the water resistance is undesirably reduced. If the softening point of the hydroxyl group-containing resin is less than 50, the water resistance of the coating film may be reduced, and the component may bleed on the surface of the coating film and the tackiness may remain.

For this reason, it has excellent water resistance, has a low content of the ventilating substance benzopyrene, and has a lighter and browner color than tar.
