The present invention relates to a heat-resistant rust-preventing composition containing petrolatum as a main component and useful as a rust-preventing material for metal structures in high-temperature corrosive environments. Conventionally, in this type of rust-preventing composition, due to the temperature characteristics of petrolatum, the composition is not likely to flow down metal structures used in high-temperature corrosive environments, such as piping that transports high-temperature fluids such as steam piping. I couldn't use it because it was stored away. In addition, even in pipelines and other piping used outdoors, the temperature of the surface of the steel pipe becomes quite high when exposed to direct sunlight such as in the summer, causing the composition to soften or, in extreme cases, to drip. This caused problems in terms of rust prevention performance and appearance. The present invention has been made in view of the above circumstances, and at the same time effectively prevents metal structures used in high-temperature corrosive environments from becoming soft or eventually sagging even in such environments. It is an object of the present invention to provide a rust preventive composition that has heat resistance and does not fall off. According to the present invention, petrolatum as a main component, an inorganic filler, and a fluidization of the composition under a high temperature atmosphere.
It contains a thickener to prevent run-off and at least one of petrolatum oxide metal salt or sulfonic acid metal salt as a rust preventive agent to further improve the rust prevention effect. The composition is characterized by its thixotropic effect, which shows fluidity when an external force is applied, but does not flow in a static state, so that the composition does not flow or flow down even at high temperatures. The specific blending range of the present invention is 100 parts by weight of petrolatum, 40 to 160 parts by weight of inorganic filler, 1 to 50 parts by weight of thickener, and further added petrolatum oxide metal salt or petrolatum oxide. An appropriate amount of at least one of the sulfonic acid metal salts is added. Petrolatum used in the present invention is not particularly limited, but includes dark green, green, red,
Amber, light amber, etc. (JIS K 2237) are suitable. Examples of inorganic fillers include inert silica, clay, calcium carbonate, talc, silicic acid, asbestos, diatomaceous earth, graphite, and glass fiber. Suitable thickeners include inorganic thickeners such as ultrafine silica, ultrafine precipitated calcium carbonate, and bentonite, as well as metal soaps such as zinc stearate and aluminum stearate, organic bentonite, and polyethylene oxide. Organic thickeners such as the following can also be used. The amount of petrolatum oxide metal salt and sulfonic acid metal salt, which are rust preventive materials, depends on the application, the required rust preventive performance, etc., but is usually about 5 parts by weight. In the present invention, the blending ratio of the inorganic filler is set to 40 to 160 parts by weight to 100 parts by weight of petrolatum because if it is less than 40 parts by weight, the viscosity of the composition will be low and the heat resistance will be low; This is because if the amount exceeds 50%, the adhesiveness of the composition will be lost and the adhesion to the metal surface to be rust-prevented will deteriorate, resulting in a decrease in the rust-preventing effect. The reason why the proportion of the thickener is 1 to 50 parts by weight is because if it is less than 1 part by weight, it will not be possible to impart sufficient thickening effect and thixotropy to the composition, and the composition will not be stable under high temperature atmosphere. On the other hand, if the amount exceeds 50 parts by weight, the adhesion between the composition and the metal surface deteriorates and the antirust effect decreases, as in the case of inorganic fillers. Next, the antirust performance and heat resistance of Examples of the present invention were investigated by softening the composition, and the results will be explained in comparison with conventional antirust compositions containing petrolatum as a main component. First, for 100 parts by weight of the main ingredient petrolatum,
Talc, ultrafine silica, petrolatum oxide Ca
Blending salts, sulfonic acid Ba salts, etc. in various proportions,
A polyester nonwoven fabric was impregnated with the obtained compositions of Examples and Comparative Examples to prepare tapes with a thickness of 1.1 mm. Next, this tape was wrapped twice around a cold rolled steel plate (JIS G 3141), 1.0 x 50 x 100 mm.
It was left for 30 days at 90°C and a humidity of 95% or higher. The results were as shown in the table below. Note that the reference examples in this table show the case where the cold-rolled steel plate was not treated with the rust-preventing composition.

[Table] According to the above table, as a matter of course, rust generation was observed in the reference example which was not treated with the antirust composition. Furthermore, in Comparative Examples 1 to 5, which did not meet the conditions of the present invention, dripping of the composition and generation of rust were observed. In contrast, embodiments 1 to 1 of the present invention
It was found that in all cases No. 3, not only did rust occur, but the composition also did not run down. As described above, according to the present invention, in addition to petrolatum as a main component, an inorganic filler, a thickener that prevents the composition from flowing or flowing down in a high-temperature atmosphere, and petrolatum oxide that improves the rust prevention effect are added. Because it contains at least one of metal salts and sulfonic acid metal salts in an appropriate range, it not only has good adhesion to metal structures and high rust prevention performance, but also has good heat resistance and can be used in high-temperature corrosive environments. It is possible to provide an excellent heat-resistant rust-preventing composition that does not soften or drip even when exposed to heat.
