A method for suppressing corrosion under insulation includes a step of applying a paste containing aerogel particles and a liquid medium to a target surface to form a coating film. A paste for suppressing corrosion under insulation contains aerogel particles and a liquid medium.
Claims12
A method for suppressing the corrosion of a pipe under insulation, comprising a step of applying a paste comprising aerogel particles, a liquid medium, a binder resin, and a fibrous substance to a surface of the pipe to form a corrosion-resistant coating film thereon,
- wherein the binder resin comprises a first binder resin and a second binder resin having a lower solubility to the liquid medium than the first binder resin, and the first binder resin is a cellulose-based resin or an acrylic acid-based resin, and
- wherein the content of the fibrous substance is 5 parts by mass or more and 25 parts by mass or less, with respect to 100 parts by mass of the aerogel particles.
