Definitions

  • the present invention has been made to solve the above-described problems, and has an object to provide a safe coating film removing agent having excellent coating film removing performance.
  • a safe coating film removing agent having excellent coating film removing performance.
  • it is possible to remove only the top coating film formed by applying a room temperature drying paint on the base coating film without removing the base coating film formed by applying the reaction curable coating material. It aims at providing the coating-film removal agent which can be performed.
  • the above-mentioned problem is at least one inorganic fine particle selected from the group consisting of activated carbon fine particles, metal oxide fine particles and metal salt fine particles, and / or at least one organic material selected from the group consisting of cereal powder and starch.
  • This problem can be solved by providing a coating film removing agent comprising a dispersion liquid containing the above fine particles and a dispersion medium mainly composed of alcohol having 2 to 3 carbon atoms.
  • the coating film removing agent contains the inorganic fine particles and the dispersion medium.
  • the inorganic fine particles are at least one kind of inorganic fine particles selected from the group consisting of zeolite, talc, activated carbon, calcium carbonate, silica alumina, silica, calcium hydroxide, zinc oxide, titanium oxide, and barium carbonate. More preferably.
  • the true density of the inorganic fine particles is also preferably 1.5 to 3 g / cm 3 . It is also preferable that the inorganic fine particles have an average particle size of 0.1 to 100 ⁇ m.
  • a preferred embodiment of the present invention is a coating film removing sheet obtained by impregnating a sheet base material with the coating film removing agent. At this time, it is preferable that a dispersion medium evaporation preventing layer is provided on one side of the sheet base material.
  • the coating film removal sheet is preferably provided with a dispersion medium evaporation preventing layer on one side of the sheet base material.
  • a dispersion medium evaporation preventing layer By providing the dispersion medium evaporation preventing layer, the evaporation of the dispersion medium in the coating film removing agent is suppressed, and the decrease in the coating film removing performance is suppressed during the standing time.
  • the dispersion medium evaporation preventing layer is provided on the surface of the sheet substrate opposite to the surface to be attached to the coating film to be removed.
  • the dispersion medium evaporation preventing layer is not particularly limited as long as it is made of a material that is difficult for the dispersion medium to permeate. Usually, a resin film, metal foil, paper or the like is used.
  • Example 3 In Example 1, as the zeolite particles, proton type mordenite powder was used instead of proton type Y zeolite powder, and the blending amounts of zeolite particles and 2-propanol were changed to 10 g and 15.6 g (20 mL), respectively. A coating film removing agent was prepared in the same manner as in Example 1 except that the coating film removal performance was evaluated.
  • proton type mordenite powder H-mordenite “HS-690” manufactured by Wako Pure Chemical Industries, Ltd. was used as proton type mordenite powder.
  • Example 7 In Example 1, calcium carbonate powder was used instead of proton type Y zeolite powder as inorganic fine particles, and the blending amounts of calcium carbonate powder and 2-propanol were changed to 40 g and 78.1 g (100 mL), respectively. Except for the above, a coating film removing agent was prepared in the same manner as in Example 1, and the coating film removing performance was evaluated. The obtained results are shown in Table 1.
  • Example 20 In Example 1, the coating film removing performance was evaluated in the same manner as in Example 1 except that the standing time was changed to 5 minutes, 30 minutes, and 60 minutes instead of 10 minutes. When the standing time was 5 minutes, the remaining of the top coat film was slightly observed. On the other hand, when the standing time was set to 30 minutes and 60 minutes, as in the case of 10 minutes, the top coat film could be removed cleanly, and damage to the base coat film was not recognized.
