Summary:To provide a process oil for rubber processing and a rubber composition comprising the same that are capable of facilitating rubber compounding processability without a significant increase in the oil input, improving mechanical properties of rubber, and inhibiting an oil decrease phenomenon.SOLUTION: A process oil for rubber processing comprises: a base oil; a liquid olefin copolymer dissolvable in the base oil and prepared by copolymerization of ethylene with an alpha-olefin having 3 to 20 carbon atoms; polyisobutylene; and one or more additives selected from alkylated phosphonium phosphate compounds and butylhydroxybenzene-based compounds. A rubber composition comprising the same is also provided.SELECTED DRAWING: None 【課題】オイル投入量を大幅に増加させることなくゴム配合加工性を向上させることができ、ゴムの機械的物性を向上させることができ、オイル減少現象を抑制することができるゴム加工用プロセスオイル及びこれを含むゴム組成物を提供する。【解決手段】本発明は、ベースオイルと、前記ベースオイルに溶解し、エチレンと炭素数3~20のアルファオレフィンとの共重合によって製造された液状オレフィン共重合体と、ポリイソブチレンと、アルキル化ホスホニウムホスフェート化合物及びブチルヒドロキシベンゼン系化合物の中から選択される1種以上の添加剤と、を含む、ゴム加工用プロセスオイル、並びにこれを含むゴム組成物を提供する。【選択図】なし
