Problems solved by technology

Since its corrosion rate is faster than the general corrosion that occurs in the outdoor atmosphere, it becomes a big problem in the maintenance and management of plant structures
[0003] In addition, regarding the above-mentioned CUI, since the corrosion and erosion position is under (surrounded by) the insulation material, the moisture that once invaded may easily remain and maintain a wet state for a long time, and the piping is exposed to high temperature due to the operating conditions of the plant, so , can promote the progress of corrosion as an oxidation reaction, and since the plant structures are often installed in seashore areas rich in sea salt particles that can cause corrosion factors, the above-mentioned corrosion is easy because the sea salt particles promote the progress of corrosion, etc. Seriousness has also become a problem

[0178] Add each raw material listed in the main ingredient column of Table 1 to the container in the amount (parts by mass) listed in Table 1, and stir with a high-speed disperser to uniformly disperse it, thereby preparing the main ingredient component.

[0179] However, the details of each component described in Table 1 are shown in Table 2. In addition, the solid content (mass %) of each component in Table 2 is a manufacturer's catalog value.

[0185] Mix 100 parts by mass of the prepared main ingredient and 1.5 parts by mass of KP-390 as a curing accelerator to obtain a coating composition, and use a film coater with a gap of 700 μm to coat the obtained coating composition on SS400 blasting (equivalent to ISO8501-1Sa2 1 / 2) steel plate, so that the dry film thickness becomes 250μm.

[0186] The coating composition coated on the steel plate was dried at 23° C. for 7 days to prepare a test piece (subs...

Abstract

An embodiment of the present invention relates to a heat-resistant coating composition, a heat-resistant coating film, a heat-resistant coating film-attached substrate, or a method for preparing same, said heat-resistant coating composition including a siloxane-based binder (A), an aluminum powder (B), and an anti-corrosive pigment containing a magnesium phosphate-based compound.

Description

technical field [0001] One embodiment of the present invention relates to a heat-resistant coating composition, a heat-resistant coating film, a substrate with a heat-resistant coating film, or a method for producing the same. Background technique [0002] In the piping of plant structures, etc., in order to prevent heat dissipation to and absorption of heat from the outside air and to suppress energy consumption, heat insulating materials are often installed around the piping (steel pipes). However, sometimes rainwater intruding into the gap between the above-mentioned insulation material and steel (for example: carbon steel, low alloy steel) pipe or the moisture condensed at this position forms a water film on the surface of the steel pipe and corrosion under insulation material (CUI: Corrosion Under Insulation) occurs. ). This CUI means that corrosion cells are formed on the steel pipe surface due to the above-mentioned water film, and local corrosion erosion occurs. Si...
