供することができる。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasticizer for rubber. [0002] An extract is known as a conventional plasticizer for rubber. Extracts have been used because they have a very high solubility in rubber. [0003] As described above, although the extract has the advantage of high solubility, it has a problem in safety. That is, it has been recognized that the extract has a particularly high carcinogenicity as a problem. The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a plasticizer for rubber which is safe and has excellent performance. [0004] To achieve the above object, the inventors of the present invention have made intensive studies and have found that a rubber plasticizer (a rubber plasticizer) can be obtained by mixing a naphthenic base oil and a naphthenic asphalt. Process oil). The present invention has been made based on this finding. DESCRIPTION OF THE PREFERRED EMBODIMENTS A plasticizer for rubber is produced by mixing a naphthenic base oil and a naphthenic asphalt, which have been subjected to high-pressure / high-temperature hydrorefining, at a specified ratio. The plasticizer for rubber according to the present invention can be produced by mixing a high-pressure / high-temperature hydrorefined naphthenic base oil and a naphthenic asphalt at a specified ratio. Here, as shown in Table 1, the prescribed ratio of mixing is, assuming that the whole is 100% by mass, 37% by mass of naphthenic asphalt with respect to 63% by mass of naphthenic base oil.
And when I got a good result. The physical properties of the rubber plasticizer other than the specified ratio are as shown in Table 1. "A / O MIX." Described in Table 1 is a trademark and indicates the plasticizer for rubber according to the present invention. [Table 1] When a test was conducted on the plasticizer for rubber according to the present invention, it was confirmed that the same solubility as that of the conventional extract was obtained. Furthermore, in terms of safety, from the academic point of view of hydrocarbons, it was found that the plasticizer for rubber has no risk of carcinogenesis, and furthermore, the OSHA standard in the United States and the safety standard of less than 3% of PCA in the EU. It turned out that both were cleared. According to the present invention, it is possible to provide a safe and excellent rubber plasticizer which can replace the conventionally used extract.
