Embodiment 1

[0196] 9.7 parts by mass of New Solvent A, 2 parts by mass of n-butanol, 6.05 parts by mass of xylene, 0.2 parts by mass of Disperbyk-180 and 0.05 parts by mass of BYK-320 were added to the container, and 30.3 parts by mass of SILRES REN80 and 1 part by mass of DISPARLON 6650 were added parts and 4 parts by mass of LF ボウセイZP-N, and stir with a high-speed disperser to uniformly disperse.

[0197] To the obtained mixture, 36.9 parts by mass of Mica Powder 100mesh was added and stirred, and the temperature of the mixture was raised to 58°C by the heat generated by the stirring.

[0198] Then, 8.3 parts by mass of MIOX 325mesh was added, stirred and uniformly dispersed, cooled to below 30°C, 1.5 parts by mass of D-15 was added, stirred, uniformly dispersed, and filtered through a 60-mesh nylon mesh to prepare a coating composition.

Embodiment 2～14 and comparative example 1～3

[0200] A coating composition was prepared in the same manner as in Example 1, except that the raw materials described in the table were used in the amounts described in Tables 2 to 5. However, the numerical values ​​described in the raw material column of Tables 2 to 5 represent parts by mass.

[0201] In addition, the details of each raw material described in Tables 2 to 5 are shown in Table 1.

[0202] However, the solid content (mass %) of each component in Table 1 is the manufacturer's catalog value.

Abstract

An object of the present invention is to provide a heat-resistant coating composition capable of forming a coating film exhibiting excellent corrosion resistance even under severe corrosive environments such as "under heat insulating material" without heating and drying when forming a coating film. The solution to the problem of the present invention is that the present invention relates to a heat-resistant coating composition, a heat-resistant coating film, a substrate with a heat-resistant coating film, and a method for producing the same, the heat-resistant coating composition containing a silicone-based binder (A), mica (B) and mica-like iron oxide (C).

Description

technical field [0001] The present invention relates to a heat-resistant coating composition, a heat-resistant coating film, a base material with the heat-resistant coating film, and a method for producing the same. Background technique [0002] In piping of a plant structure or the like, in order to prevent heat dissipation to or heat absorption from the outside air and to suppress energy consumption, a heat insulating material is often provided around the piping (steel pipe). However, rainwater that penetrates into the gap between the above-mentioned insulating material and the steel (for example, carbon steel, low-alloy steel) pipe, or the water condensed at the position may form a water film on the surface of the steel pipe and cause corrosion under the insulating material (CUI: Corrosion Under Insulation). ). The CUI means that a corrosion cell is formed on the surface of the steel pipe due to the above-mentioned water film, and localized corrosion corrosion occurs. S...
