When using naphthene-based mineral oil, the rust prevention ability is good in winter or in cold regions, but because the viscosity index is small, the viscosity decreases significantly at high temperatures, and the rust prevention ability decreases in summer, causing trouble. The disadvantage is that it is easier to do. Also,
When used as a rust preventive oil for switching rail points, there is a risk of swelling and deterioration of the covering of electric wires attached to the rail points.
一方、パラフィン基系鉱油を用いた場合には、夏期にお

使用した場合、流動性がなくなって固化するため、防錆
能が失われるとともに、潤滑性も消失し、レールのポイ
ント切替用防錆油としては不適当なものとなる。On the other hand, when paraffin-based mineral oil is used, it has good rust prevention ability in summer, but it solidifies and cracks in the coating at low temperatures, resulting in coating defects, and in winter or in cold regions. There are many problems with rust. Furthermore, when used at low temperatures, it loses its fluidity and solidifies, resulting in a loss of rust prevention ability and lubricity, making it unsuitable as a rust prevention oil for rail point switching.
このように、従来の防錆油組成物は、冬期あるいは夏期
のいずれかの時期に防錆能が著しく低下するため、冬用

した。Therefore, the present inventor has developed a rust-preventing oil composition that has good rust-preventing ability under any temperature conditions, whether it is winter or summer, that is, whether it is low temperature or high temperature, and does not require oil change depending on the season. He conducted extensive research to develop the product. As a result, it has been found that mineral oil with specific properties is used as a base oil and a rust preventive additive is blended with this base oil to have the desired properties.

The kinematic viscosity at 0°C is 1. It ranges from O to 500 cSt, preferably from 2.0 to 300 cSt. Kinematic viscosity is 1. Q
If it is less than cst, the rust prevention ability will be poor, while if it is less than 500cS
If it exceeds t, the viscosity will be too high and it will be difficult to handle. In addition, this mineral oil has an aniline point of 90°C or higher,
The temperature is preferably 95°C or higher, most preferably 100°C or higher. If the aniline point is less than 90° C., the viscosity decreases significantly at high temperatures, leading to a decrease in rust prevention ability in summer and the possibility of inhibiting the coating.

ル性に問題が生ずる。On the other hand, when a paraffin base oil is used, the rust prevention property at low temperatures is poor (Comparative Example 2), and when a naphthene base oil is used, the rust prevention property at high temperatures is reduced. However, problems arise with rubber sealing properties.
叙上の如く、本発明の防錆油組成物は、夏期。 As mentioned above, the rust preventive oil composition of the present invention is suitable for use in summer.
冬期を問わず良好な防錆性ならびにゴムシール性を有し
、各種の防錆油、さらには鉄道のレールポイント切替用
防錆油として有効に利用される。It has good rust prevention properties and rubber sealing properties regardless of the winter season, and is effectively used as a variety of rust prevention oils and even as a rust prevention oil for railway rail point switching.
