The invention discloses an oil-resistant rubber material without free-state sulfur, and relates to a rubber material. Adopted matrix rubber is mixed rubber of nitrile rubber (N41) and rubber alloy (N7030), an adopted sulfuration system is sulfur-carrier thiuram (TMTD or TRA) sulfuration agents without elemental sulfur, adopted sulfuration accelerators are sulfenamide (CZ) or thiazoles (DM), adopted anti-aging agents are amine (RD and 4010NA) anti-aging agents, adopted fillers are one or two kinds of CaCO3, talcum powder and spraying carbon black, adopted reinforcing agents are a mixture of N330, N550 and N774, adopted plasticizers are ester plasticizers (DOS), and a binding system is a mixture of novel binding agents (AS-88) and white carbon black (WCB). According to the oil-resistant rubber material, as sulfur carriers are used as the sulfuration agents, the prepared rubber material is good in oil resistance, does not contain the free-state sulfur, and is more environmentally friendly accordingly, and various properties can meet the national oil resistant rubber pipe standard.
